[0001] Sequence List This application is filed together with an electronic sequence listing. The sequence listing is provided as a 29kb file named BIOL0320USL2SEQ_ST25.txt, created on August 30, 2018. The electronic information of the sequence listing is incorporated herein by reference in its entirety.
[0002] This embodiment provides compounds and methods for targeting cells expressing the GLP-1 receptor. [Background technology]
[0003] The GLP-1 receptor is a class 2 G protein-coupled receptor that binds to adenylyl cyclase via a stimulating G protein receptor. Intestinal nutritional stimulation releases glucagon-like peptide-1 into circulation. Circulating GLP-1 binds to GLP-1 receptors on β-islet cells of the pancreas. This activates the GLP-1 receptor, inducing a signaling event that leads to insulin exocytosis from the β-islet cells. The binding of GLP-1 and the GLP-1 receptor causes the receptor to translocate into the cytoplasm and ultimately be sorted into lysosomes (Non-Patent Literature 1).

Therefore, for example, an MOE nucleoside and an unmodified DNA nucleoside are "differentially modified," even if the DNA nucleoside is unmodified. Similarly, DNA and RNA are "differentially modified," even if both are naturally occurring unmodified nucleosides. Nucleosides that are identical except for containing different nucleic acid bases are not differentially modified. For example, a nucleoside containing a 2'-OMe modified sugar and an unmodified adenine nucleic acid base is not differentially modified, as is a nucleoside containing a 2'-OMe modified sugar and an unmodified thymine nucleic acid base.

[0068] The term "selective" in relation to an effect means that the effect on one cell is greater than that on another cell by any given quantitative range or multiplier. For example, a compound containing a GLP-1 receptor conjugate ligand moiety that is "selective" to cells expressing the GLP-1 receptor, or a compound that "selectively" targets cells expressing the GLP-1 receptor, will target GLP-1 receptor-expressing cells to a greater degree than a compound that does not contain the GLP-1 receptor conjugate ligand moiety. As another example, a compound containing a GLP-1 receptor conjugate ligand moiety that is "selective" to cells expressing the GLP-1 receptor, or a compound that "selectively" targets cells expressing the GLP-1 receptor, will target GLP-1 receptor-expressing cells to a greater degree than cells that do not express the GLP-1 receptor or express it at relatively low levels. It should be understood that the term "selective" does not require absolute all-or-nothing selectivity.
[0069] In relation to a compound, "single-stranded" means that the compound has only one oligonucleotide. "Self-complementary" means that the oligonucleotide hybridizes with itself, at least partially. A compound consisting of one oligonucleotide, where the oligonucleotide is self-complementary, is a single-stranded compound. A single-stranded compound can bind to a complementary compound to form a double-stranded compound.

In certain such embodiments, the compounds described herein include oligonucleotides having binding subunit lengths in the range defined by 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, or 80 or any two of the above values.In some embodiments, the binding subunit is a nucleotide, nucleoside, or nucleic acid base.
[0197] In certain embodiments, the compound may further include additional features or elements, such as a conjugate group attached to the oligonucleotide. In certain embodiments, such a compound is an antisense compound. In certain embodiments, such a compound is an oligomeric compound. In embodiments in which the conjugate group includes a nucleoside (i.e., a nucleoside that binds the conjugate group to the oligonucleotide), the nucleoside of the conjugate group is not counted in the length of the oligonucleotide.
[0198] In certain embodiments, compounds may be shortened or truncated. For example, a single subunit may be deleted from the 5' end (5' truncation) or alternatively from the 3' end (3' truncation). Shortened or truncated compounds targeting nucleic acids may have two subunits deleted from the 5' end of the compound, or alternatively, two subunits deleted from the 3' end. Alternatively, the deleted nucleoside may be dispersed throughout the compound.
[0199] If a single additional subunit is present in the extended compound, the additional subunit may be located at the 5' or 3' end of the compound. If two or more additional subunits are present, the added subunits may be adjacent to each other, for example, two subunits may be added to the 5' end of the compound (5' addition) or alternatively to the 3' end (3' addition). Alternatively, the added subunits may be dispersed throughout the compound.
[0200] It is possible to increase or decrease the length of compounds such as oligonucleotides and / or introduce mismatched bases without eliminating their activity (Woolf et al. (Proc.Natl.Acad.Sci.USA 89:7305-7309,1992; Gautschi et al. J.Natl.Cancer Inst.93:463-471,March 2001; Maher and Dolnick Nuc.Acid.Res.16:3341-3358,1988). However, seemingly small changes in oligonucleotide sequence, chemical structure, and motifs can result in one or more significant differences in many properties required for clinical development (Seth et al. J.Med.Chem.2009,52,10; Egli et al. J.Am.Chem.Soc.2011,133,16642).
[0201] In certain embodiments, the compounds described herein are interfering RNA compounds (RNAi), including double-stranded RNA compounds (also referred to as short interfering RNA or siRNA) and single-stranded RNAi compounds (or ssRNA). Such compounds function at least partially via the RISC pathway to degrade and / or blockade target nucleic acids (hence, microRNA / microRNA mimetic compounds). As used herein, the term siRNA is equivalent to other terms used to describe nucleic acid molecules that can mediate sequence-specific RNAi, such as short interfering RNA (siRNA), double-stranded RNA (dsRNA), microRNA (miRNA), short hairpin RNA (shRNA), short interfering oligonucleotides, short interfering nucleic acids, short interfering modified oligonucleotides, chemically modified siRNA, post-transcriptional gene silencing RNA (ptgsRNA), etc. Furthermore, as used herein, the term "RNAi" is equivalent to other terms used to describe sequence-specific RNA interference, such as post-transcriptional gene silencing, translation inhibition, or epigenetics.
[0202] In certain embodiments, the first strand of the compound is a siRNA guide strand and the second strand of the compound is a siRNA passenger strand. In certain embodiments, the second strand of the compound is complementary to the first strand. In certain embodiments, each strand of the compound is 16, 17, 18, 19, 20, 21, 22 or 23 linked nucleosides in length. In certain embodiments, the first or second strand of the compound can include a conjugate group.
[0203] In certain embodiments, the compounds described herein include modified oligonucleotides. Certain modified oligonucleotides have one or more asymmetric centers and thus give rise to enantiomers, diastereomers and other stereoisomeric forms, the stereoisomeric forms of which can be defined as (R) or (S) from the perspective of absolute stereochemistry, e.g., α or β with respect to sugar anomers or (D) or (L) with respect to amino acids, etc. The modified oligonucleotides provided herein include all such possible isomers in their racemic and optically pure forms, unless otherwise specified. Similarly, all cis- and trans-isomers as well as tautomers are included.
[0204] The compounds described herein include variations in which one or more atoms are replaced with non-radioactive or radioactive isotopes of the indicated element. For example, compounds herein that include hydrogen atoms include all possible deuterium substitutions of each 1 H hydrogen atom. Isotope substitutions included by the compounds herein include, but are not limited to, 1 in place of 2 H or 3 H, 12 in place of 13 C or 14 C, 14 in place of 15 N, 16 in place of 17 O or 18 O and 32 in place of 33 S, 34 S, 35 S or 36S is one example. In certain embodiments, non-radioactive isotope substitution can impart new properties to compounds that are beneficial for use as therapeutic or research tools. In certain embodiments, radioactive isotope substitution can produce compounds suitable for research or diagnostic purposes, such as imaging assays.
[0205] Specific mechanism In certain embodiments, the compounds described herein include or consist of modified oligonucleotides. In certain embodiments, the compounds described herein are antisense compounds. In certain embodiments, the compounds include oligomeric compounds. In certain embodiments, the compounds described herein are capable of hybridizing to a target nucleic acid to yield at least one antisense activity. In certain embodiments, the compounds described herein selectively affect one or more target nucleic acids. Such compounds include nucleic acid sequences that hybridize to one or more target nucleic acids to yield one or more desired antisense activities, and do not hybridize to one or more non-target nucleic acids, or do not hybridize to one or more non-target nucleic acids in a manner that yields undesirable significant antisense activity.
[0206] In certain antisense activities, hybridization of the compounds described herein to target nucleic acids results in the recruitment of proteins that cleave the target nucleic acid. For example, certain compounds described herein result in RNase H-mediated cleavage of the target nucleic acid. RNase H is a cellular endonuclease that cleaves the RNA strand of an RNA:DNA double helix. The DNA in such an RNA:DNA double helix does not need to be unmodified DNA. In certain embodiments, the compounds described herein are sufficiently "DNA-like" to induce RNase H activity. Furthermore, in certain embodiments, one or more non-DNA-like nucleosides in the gapmer gap are tolerable.
[0207] In certain antisense activities, the compounds or parts of the compounds described herein are loaded into an RNA-induced silencing complex (RISC), ultimately leading to the cleavage of the target nucleic acid. For example, certain compounds described herein lead to the cleavage of the target nucleic acid by Argonaute. The compounds loaded into the RISC are RNAi compounds. RNAi compounds may be double-stranded (siRNA) or single-stranded (ssRNA).
[0208] In certain embodiments, hybridization of the compounds described herein to a target nucleic acid does not result in the recruitment of proteins that cleave the target nucleic acid. In certain such embodiments, hybridization of the compounds to a target nucleic acid results in a change in the splicing of the target nucleic acid. In certain embodiments, hybridization of the compounds to a target nucleic acid results in the inhibition of binding interactions between the target nucleic acid and proteins or other nucleic acids. In certain such embodiments, hybridization of the compounds to a target nucleic acid results in a change in the translation of the target nucleic acid.
[0209] Antisense activity can be observed directly or indirectly. In certain embodiments, observation or detection of antisense activity includes observing or detecting changes in the amount of target nucleic acid or protein encoded by such target nucleic acid, changes in the ratio of splice variants of nucleic acid or protein, and / or phenotypic changes in cells or animals.
[0210] Target nucleic acid, target region, and nucleotide sequence In certain embodiments, the compounds described herein comprise or consist of an oligonucleotide comprising a region complementary to a target nucleic acid. In certain embodiments, the target nucleic acid is an endogenous RNA molecule. In certain embodiments, the target nucleic acid is a non-coding RNA. In certain embodiments, the target nucleic acid encodes a protein. In certain such embodiments, the target nucleic acid is selected from mRNA and pre-mRNA comprising introns, exons, and untranslated regions. In certain embodiments, the target RNA is mRNA. In certain embodiments, the target nucleic acid is pre-mRNA. In certain such embodiments, the target region is entirely within an intron. In certain embodiments, the target region spans an intron / exon junction. In certain embodiments, the target region is at least 50% within an intron. In certain embodiments, the target nucleic acid is present within a cell expressing the GLP-1 receptor. In certain embodiments, the GLP-1 receptor-expressing cells are pancreatic cells such as β-islet cells.
[0211] Hybridization In some embodiments, hybridization occurs between the compounds disclosed herein and a target nucleic acid. The most common mechanism of hybridization involves hydrogen bonding between complementary nucleobases of nucleic acid molecules (e.g., Watson-Crick, Hoogsteen or reverse Hoogsteen type hydrogen bonds).
[0212] Hybridization can occur under variable conditions. Hybridization conditions are sequence-dependent and are determined by the nature and composition of the nucleic acid molecules being hybridized.
[0213] Methods for determining whether a sequence specifically hybridizes to a target nucleic acid are well known in the art. In certain embodiments, the compounds provided herein are capable of specifically hybridizing to a target nucleic acid.
[0214] Complementarity An oligonucleotide is described as complementary to another nucleic acid if the nucleic acid base sequence of such oligonucleotide or one or more regions thereof matches the nucleic acid base sequence of another oligonucleotide or nucleic acid or one or more regions thereof when these two nucleic acid base sequences are aligned in opposite directions. Unless otherwise specified, the nucleic acid base matches or complementary nucleic acid bases described herein are limited to the following pairs: adenine (A) and thymine (T), adenine (A) and uracil (U), cytosine (C) and guanine (G), and 5-methylcytosine (mC) and guanine (G). Complementary oligonucleotides and / or nucleic acids do not need to have nucleic acid base complementarity at each nucleoside and may contain one or more nucleic acid base mismatches. An oligonucleotide is fully complementary or 100% complementary if such oligonucleotide has nucleic acid base matches at each nucleoside without any nucleic acid base mismatches.
[0215] In certain embodiments, the compounds described herein include or consist of modified oligonucleotides. In certain embodiments, the compounds described herein are antisense compounds. In certain embodiments, the compounds include oligomeric compounds. Non-complementary nucleic acid bases between the compound and the target nucleic acid may be tolerable if they remain in a state where they can specifically hybridize to the target nucleic acid. Furthermore, since the compound can hybridize across one or more segments of the target nucleic acid, intervening or adjacent segments do not participate in the hybridization event (e.g., loop structures, mismatches, or hairpin structures).
[0216] In certain embodiments, the compounds or specific portions thereof provided herein are complementary to the target nucleic acid, target region, target segment, or specific portion thereof by at least 70%, 80%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100%, or up to these percentages. In certain embodiments, the compounds or specific portions thereof provided herein are complementary to the target nucleic acid, target region, target segment, or specific portion thereof by 70%-75%, 75%-80%, 80%-85%, 85%-90%, 90%-95%, 95%-100%, or any number within these ranges. The percentage of complementarity of the compound with the target nucleic acid can be determined using common methods.
[0217] For example, a compound in which 18 of its 20 nucleic acid bases are complementary to the target region and therefore specifically hybridizes will exhibit 90 percent complementarity. In this example, the remaining non-complementary nucleic acid bases can cluster or be scattered among the complementary nucleic acid bases and do not need to be consecutive with each other or with complementary nucleic acid bases. Thus, a compound with an 18-nucleotide length having four non-complementary nucleic acid bases adjacent to two regions that are perfectly complementary to the target nucleic acid will have 77.8% overall complementarity with the target nucleic acid. The percentage complementarity of a compound with a region of the target nucleic acid can be systematically determined using the BLAST (Basic Local Alignment Search Tool) and PowerBLAST programs (Altschul et al., J.Mol.Biol., 1990, 215, 403 410; Zhang and Madden, Genome Res., 1997, 7, 649 656), which are known in the art. Homology percentages, sequence identity percentages, or complementarity percentages can be determined, for example, using the default settings of the Gap program (Wisconsin Sequence Analysis Package, Version 8 for Unix, Genetics Computer Group, University Research Park, Madison Wis.) which employs the Smith and Waterman algorithm (Adv.Appl.Math., 1981, 2, 482 489).
[0218] In certain embodiments, the compounds or specific portions thereof described herein are fully complementary (i.e., 100% complementary) to the target nucleic acid or specific portion thereof. For example, a compound may be fully complementary to the target nucleic acid or its target region, target segment, or target sequence. As used herein, “fully complementary” means that each nucleic acid base of the compound is complementary to the corresponding nucleic acid base of the target nucleic acid. For example, a 20-nucleotide compound is fully complementary to a 400-nucleotide-length target sequence, insofar as there is a 20-nucleotide portion of the target nucleic acid that is fully complementary to the compound. “Fully complementary” can also be used in reference to specific portions of a first and / or second nucleic acid. For example, a 20-nucleotide portion of a 30-nucleotide compound may be “fully complementary” to a 400-nucleotide-length target sequence. The 20-nucleotide portion of a 30-nucleotide compound is fully complementary to the target sequence if the target sequence has a corresponding 20-nucleotide portion where each nucleic acid base is complementary to the 20-nucleotide portion of the compound. At the same time, the entire 30-nucleotide compound may or may not be perfectly complementary to the target sequence, depending on whether the remaining 10 nucleotides of the compound are complementary to the target sequence.
[0219] In certain embodiments, the compounds described herein contain one or more nucleic acid bases that are mismatched with respect to a target nucleic acid. In certain such embodiments, antisense activity against the target is reduced by such mismatch, but activity against non-targets is reduced more significantly. Thus, in certain such embodiments, the selectivity of the compound is improved. In certain embodiments, the mismatch is specifically located within oligonucleotides having a gapmer motif. In certain such embodiments, the mismatch is located at positions 1, 2, 3, 4, 5, 6, 7, or 8 from the 5' end of the gap region. In certain such embodiments, the mismatch is located at positions 9, 8, 7, 6, 5, 4, 3, 2, or 1 from the 3' end of the gap region. In certain such embodiments, the mismatch is located at positions 1, 2, 3, or 4 from the 5' end of the wing region. In certain such embodiments, the mismatch is located at positions 4, 3, 2, or 1 from the 3' end of the wing region. In certain embodiments, the mismatch is specifically located within oligonucleotides that do not have a gapmer motif. In certain such embodiments, the mismatch is located at position 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 from the 5' end of the oligonucleotide. In certain such embodiments, the mismatch is located at position 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 from the 3' end of the oligonucleotide.
[0220] The localization of non-complementary nucleic acid bases may be at the 5' or 3' end of the compound. Alternatively, one or more non-complementary nucleic acid bases may be located internally within the compound. If two or more non-complementary nucleic acid bases are present, they may be contiguous (i.e., bonded) or discontinuous. In one embodiment, the non-complementary nucleic acid bases are localized within the wing segment of a gapmer oligonucleotide.
[0221] In certain embodiments, the compounds described herein, having a nucleic acid base length of 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20, or a maximum of 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20, contain four or fewer, three or fewer, two or fewer, or one or fewer non-complementary nucleic acid bases with respect to the target nucleic acid, e.g., the target nucleic acid or a defined portion thereof.
[0222] In certain embodiments, the compounds described herein, having a nucleic acid base length of 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30 nucleic acid base lengths, or up to 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30 nucleic acid base lengths, contain six or fewer, five or fewer, four or fewer, three or fewer, two or fewer, or one or fewer non-complementary nucleic acid bases with respect to the target nucleic acid, e.g., the target nucleic acid or a defined portion thereof.
[0223] In certain embodiments, the compounds described herein may be complementary to a portion of the target nucleic acid. As used herein, “a portion” refers to a defined number of consecutive (i.e., bound) nucleic acid bases within a region or segment of the target nucleic acid. “A portion” may also refer to a defined number of consecutive nucleic acid bases of a compound. In certain embodiments, the compound is complementary to a portion of at least eight nucleic acid bases of the target segment. In certain embodiments, the compound is complementary to a portion of at least nine nucleic acid bases of the target segment. In certain embodiments, the compound is complementary to a portion of at least ten nucleic acid bases of the target segment. In certain embodiments, the compound is complementary to a portion of at least eleven nucleic acid bases of the target segment. In certain embodiments, the compound is complementary to a portion of at least twelve nucleic acid bases of the target segment.

[0239] In certain embodiments, the bicyclic sugar moiety and the nucleoside incorporating such a bicyclic sugar moiety are further defined by their isomer configuration. For example, the LNA nucleoside (as described herein) may have an α-L configuration or a β-D configuration. [ka] α-L-methyleneoxy(4'-CH2-O-2') or α-L-LNA bicyclic nucleosides have been incorporated into oligonucleotides exhibiting antisense activity (Frieden et al., Nucleic Acids Research, 2003, 21, 6365-6372). In this specification, a general description of a bicyclic nucleoside includes both isomer configurations. In the exemplary embodiments herein, when the position of a particular bicyclic nucleoside (e.g., LNA or cEt) is specified, they are in the β-D configuration unless otherwise specified.
[0240] In certain embodiments, the modified sugar moiety comprises one or more non-crosslinked sugar substituents and one or more crosslinked sugar substituents (e.g., 5'-substituted and 4'-2' crosslinked sugars).
[0241] In certain embodiments, the modified sugar moiety is a sugar substitute. In certain such embodiments, the oxygen atom of the sugar moiety is replaced with, for example, a sulfur, carbon, or nitrogen atom. In certain such embodiments, such a modified sugar moiety also includes the crosslinked and / or non-crosslinked substituents described herein. For example, certain sugar substitutes include substitutions of the 4'-sulfur atom and the 2'-position (see, for example, U.S. Patent No. 7,875,733 and U.S. Patent No. 7,939,677 of Bhat et al.) and / or the 5' position.
[0242] In certain embodiments, the sugar substitute comprises a ring having more than five atoms.

Nucleosides containing such modified tetrahydropyrans include, but are not limited to, hexitol nucleic acid ("HNA"), anitol nucleic acid ("ANA"), mannitol nucleic acid ("MNA") (see, e.g., Leumann, CJ. Bioorg. & Med. Chem. 2002, 10, 841-854), fluoroHNA: [ka] (See “F-HNA,” for example, U.S. Patent No. 8,088,904 by Swayze et al.; U.S. Patent No. 8,440,803 by Swayze et al.; U.S. Patent No. 9,005,906 by Swayze et al. F-HNA may also be referred to as F-THP or 3'-fluorotetrahydropyran), and formula: [ka] (In the formula, independently of each of the modified THP nucleosides, Bx is the nucleic acid base portion; T3 and T4 are, independently, internucleoside binding groups that bind a modified THP nucleoside to the remainder of the oligonucleotide, or one of T3 and T4 is an internucleoside binding group that binds a modified THP nucleoside to the remainder of the oligonucleotide, and the other of T3 and T4 is H, a hydroxyl protecting group, a binding conjugate group, or a 5' or 3'-terminal group; q1, q2, q3, q4, q5, q6, and q7 are each independently H, C1-C6 alkyl, substituted C1-C6 alkyl, C2-C6 alkenyl, substituted C2-C6 alkenyl, C2-C6 alkynyl, or substituted C2-C6 alkynyl; Each of R1 and R2 is independently selected from hydrogen, halogen, substituted or unsubstituted alkoxy, NJ1J2, SJ1, N3, OC(=X)J1, OC(=X)NJ1J2, NJ3C(=X)NJ1J2, and CN, where X is O, S, or NJ1, and each of J1, J2, and J3 is independently H or C1-C6 alkyl. Examples include nucleosides containing additionally modified THP compounds having [specific properties].
[0243] In certain embodiments, modified THP nucleosides are provided in which q1, q2, q3, q4, q5, q6, and q7 are each H. In certain embodiments, at least one of q1, q2, q3, q4, q5, q6, and q7 is not H. In certain embodiments, at least one of q1, q2, q3, q4, q5, q6, and q7 is methyl.

In certain embodiments, R1 is F and R2 is H, in certain embodiments, R1 is methoxy and R2 is H, and in certain embodiments, R1 is methoxyethoxy and R2 is H.
[0244] In certain embodiments, the sugar substitute comprises a ring having six or more atoms and two or more heteroatoms. For example, its use in nucleosides and oligonucleotides containing a morpholino sugar moiety has been reported (see, e.g., Braasch et al., Biochemistry, 2002, 41, 4503-4510 and U.S. Patent Nos. 5,698,685; 5,166,315; 5,185,444; and 5,034,506 by Summerton et al.). The term "morpholino" as used herein refers to the following structure: [ka] This refers to a sugar substitute having [the specified properties]. In certain embodiments, morpholino can be modified, for example, by adding or altering substituents from the morpholino structure. Such sugar substitutes are referred to herein as "modified morpholino".

Examples of nucleosides and oligonucleotides containing such acyclic sugar substitutes include, but are not limited to, peptide nucleic acids ("PNA"), acyclic butyl nucleic acids (see, e.g., Kumar et al., Org. Biomol. Chem., 2013, 11, 5853-5865), and nucleosides and oligonucleotides described in Manoharan et al.'s International Publication No. 2011 / 133876.
[0246] Numerous other bicyclic and tricyclic sugar and sugar substitute ring systems that can be used in modified nucleosides are known in the art.
[0247] Modified nucleic acid bases Modifications or substitutions of nucleic acid bases (or bases) are structurally distinct from naturally occurring or synthetically unmodified nucleic acid bases, but functionally interchangeable with them. Both naturally occurring and modified nucleic acid bases can participate in hydrogen bonding. Such nucleic acid base modifications can confer nuclease stability, binding affinity, or some other beneficial biological property to antisense compounds.

[0255] In certain embodiments, the nucleosides of modified oligonucleotides may be linked to one another using any internucleoside bond. Two main classes of internucleoside bond groups are defined by the presence or absence of a phosphorus atom. Representative phosphorus-containing internucleoside bonds include, but are not limited to, phosphates (also called unmodified or naturally occurring bonds), phosphotriesters, methylphosphonates, phosphoramidates, and phosphorothioates ("P=S") and phosphorodithioates ("HS-P=S") containing phosphodiester bonds ("P=O").

Compared to naturally occurring phosphate bonds, modified nucleoside interbonding groups can be used to alter and generally increase the nuclease resistance of oligonucleotides. In certain embodiments, nucleoside interbonding groups having chiral atoms can be prepared as racemic mixtures or as separate enantiomers. Representative chiral nucleoside interbonding groups include, but are not limited to, alkylphosphonates and phosphorothioates.

In certain embodiments, it is desirable that the number and position of phosphorothioate nucleoside bonds and the number and position of phosphodiester nucleoside bonds be arranged to maintain nuclease resistance.

[0262] 4. Specific motifs In certain embodiments, the compounds described herein include oligonucleotides. Oligonucleotides may have motifs, such as unmodified and / or modified sugar moieties, nucleic acid bases, and / or nucleoside bond patterns. In certain embodiments, a modified oligonucleotide comprises one or more modified nucleosides containing modified sugars. In certain embodiments, a modified oligonucleotide comprises one or more modified nucleosides containing modified nucleic acid bases. In certain embodiments, a modified oligonucleotide comprises one or more modified nucleoside bonds. In such embodiments, the modifications, unmodified and differentially modified sugar moieties, nucleic acid bases, and / or nucleoside bonds of the modified oligonucleotide define the pattern or motif. In certain embodiments, the sugar moieties, nucleic acid bases, and nucleoside bond patterns are independent of each other. Thus, a modified oligonucleotide can be described by its sugar motif, nucleic acid base motif, and / or nucleoside bond motif (as used herein, the nucleic acid base motif describes a modification of the nucleic acid base independent of the sequence of the nucleic acid base).
[0263] 1. Specific sugar motifs In certain embodiments, the compounds described herein include oligonucleotides. In certain embodiments, the oligonucleotide includes one or more types of modified sugars and / or unmodified sugar moieties arranged along the oligonucleotide or its region in a defined pattern or sugar motif. In certain examples, such sugar motifs include, but are not limited to, any of the sugar modifications considered herein.
[0264] In certain embodiments, the modified oligonucleotide comprises or consists of a region having a gapmer motif comprising two external regions or "wings" and a central or internal region or "gap". The three regions of the gapmer motif (5'-wing, gap, and 3'-wing) form a continuous sequence of nucleosides, and at least a portion of the sugar moieties of each nucleoside in the wings differs from at least a portion of the sugar moieties of the nucleosides in the gap. Specifically, at least the sugar moieties of the nucleosides in each wing closest to the gap (the 3'-side nucleoside of the 5'-wing and the 5'-side nucleoside of the 3'-wing) differ from the sugar moieties of the adjacent gap nucleosides, thus defining a boundary between the wings and the gap (i.e., a wing / gap junction). In certain embodiments, the sugar moieties within the gap are identical to each other. In certain embodiments, the gap comprises one or more nucleosides having sugar moieties that differ from the sugar moieties of one or more other nucleosides in the gap. In certain embodiments, the sugar motifs of the two wings are identical to each other (symmetric gapmer). In certain embodiments, the sugar motif of the 5'-wing is different from the sugar motif of the 3'-wing (asymmetric gapmer).
[0265] In certain embodiments, the gapmer wing contains 1 to 5 nucleosides. In certain embodiments, the gapmer wing contains 2 to 5 nucleosides. In certain embodiments, the gapmer wing contains 3 to 5 nucleosides. In certain embodiments, all nucleosides of the gapmer are modified nucleosides.

In certain embodiments, the gap of the gapmer contains 8 to 10 nucleosides. In certain embodiments, the gap of the gapmer contains 10 nucleosides. In certain embodiments, each nucleoside in the gap of the gapmer is an unmodified 2'-deoxynucleoside.
[0267] In certain embodiments, the gapmer is a deoxygapmer. In such embodiments, the nucleoside on the gap side of each wing / gap junction is an unmodified 2'-deoxynucleoside, and the nucleoside on the wing side of each wing / gap junction is a modified nucleoside. In certain such embodiments, each nucleoside of the gap is an unmodified 2'-deoxynucleoside. In certain such embodiments, each nucleoside of each wing is a modified nucleoside.
[0268] In certain embodiments, the modified oligonucleotide has a fully modified sugar motif, and each nucleoside of the modified oligonucleotide contains a modified sugar moiety. In certain embodiments, the modified oligonucleotide includes or comprises a region having a fully modified sugar motif, and each nucleoside of the region contains a modified sugar moiety. In certain embodiments, the modified oligonucleotide includes or comprises a region having a fully modified sugar motif, and each nucleoside within the fully modified region contains the same modified sugar moiety, which is referred to herein as a homogeneous modified sugar motif. In certain embodiments, the fully modified oligonucleotide is a homogeneous modified oligonucleotide. In certain embodiments, each nucleoside of the homogeneous modification contains the same 2'-modification.
[0269] 2. Specific nucleic acid base motifs In certain embodiments, the compounds described herein include oligonucleotides. In certain embodiments, the oligonucleotide includes modified and / or unmodified nucleic acid bases arranged along the oligonucleotide or its region in a defined pattern or motif.

In certain embodiments, the modified nucleic acid base is selected from 2-thiopyrimidine and 5-propympyrimidine.
[0272] 3. Specific nucleoside bond motifs In certain embodiments, the compounds described herein include oligonucleotides. In certain embodiments, the oligonucleotide includes modified and / or unmodified nucleoside bonds arranged along the oligonucleotide or its region in a defined pattern or motif. In certain embodiments, essentially each nucleoside bond is a phosphate nucleoside bond (P=O). In certain embodiments, each nucleoside bond of the modified oligonucleotide is a phosphorothioate (P=S). In certain embodiments, each nucleoside bond of the modified oligonucleotide is independently selected from phosphorothioate and phosphate nucleoside bonds. In certain embodiments, the sugar motif of the modified oligonucleotide is a gapmer, and all nucleoside bonds within the gap are modified. In certain such embodiments, some or all of the nucleoside bonds in the wing are unmodified phosphate bonds. In certain embodiments, the terminal nucleoside bonds are modified.
[0273] 5. Specific modified oligonucleotides In certain embodiments, the compounds described herein include modified oligonucleotides. In certain embodiments, the above modifications (sugars, nucleic acid bases, nucleoside bonds) are incorporated into the modified oligonucleotide. In certain embodiments, the modified oligonucleotide is characterized by its modifications, motif, and full length. In certain embodiments, such parameters are independent of each other. Thus, unless otherwise indicated, each nucleoside bond of an oligonucleotide having a gapmer sugar motif may be modified or unmodified and may or may not follow the gapmer modification pattern of the sugar modification. For example, nucleoside bonds within the wing region of a sugar gapmer may be identical or different from those within the gap region of the sugar motif. Similarly, such a gapmer oligonucleotide may contain one or more modified nucleic acid bases independent of the gapmer pattern of the sugar modification. Furthermore, in certain examples, the oligonucleotide is described by its full length or range and by the length or length range of two or more regions (e.g., regions of nucleosides having a particular sugar modification), in which case it may be possible to select a number of ranges that result in oligonucleotides having full length not included in a particular range. In such cases, both elements must be satisfied. For example, in a particular embodiment, the modified oligonucleotide consists of 15 to 20 bound nucleosides and has a sugar motif consisting of three regions A, B, and C, where region A consists of 2 to 6 bound nucleosides having a specific sugar motif, region B consists of 6 to 10 bound nucleosides having a specific sugar motif, and region C consists of 2 to 6 bound nucleosides having a specific sugar motif. Such embodiments do not include modified oligonucleotides where A and C each consist of 6 bound nucleosides and B consists of 10 bound nucleosides (although these numbers of nucleosides are possible within the requirements for A, B, and C). This is because the total length of such an oligonucleotide is 22, which exceeds the upper limit (20) of the total length of modified oligonucleotides.In this specification, if an oligonucleotide is described with respect to one or more parameters, those parameters are not limited. Therefore, a modified oligonucleotide described only as having a gapmer sugar motif without further description may have any length, nucleoside-binding motif, and nucleic acid base motif. Unless otherwise indicated, all modifications are independent of the nucleic acid base sequence.
[0274] Specific conjugated compounds In certain embodiments, the compounds described herein comprise or consist of an oligonucleotide (modified or unmodified) and optionally one or more conjugate groups and / or terminal groups. A conjugate group comprises one or more conjugate moieties and a conjugate linker that binds the conjugate moieties to an oligonucleotide. The conjugate group may be attached to either or both ends and / or any internal position of the oligonucleotide. In certain embodiments, the conjugate group is attached to the 2' position of the nucleoside of the modified oligonucleotide. In certain embodiments, a conjugate group attached to either or both ends of the oligonucleotide is a terminal group. In certain such embodiments, the conjugate group or terminal group is attached to the 3' and / or 5' ends of the oligonucleotide. In certain such embodiments, the conjugate group (or terminal group) is attached to the 3' end of the oligonucleotide.

[0360] Conjugate Linker In certain embodiments, the conjugate linker binds the GLP-1 receptor ligand conjugate moiety to the oligonucleotide. In certain compounds, the GLP-1 receptor ligand conjugate moiety is attached to the oligonucleotide via the conjugate linker by a single bond. In certain embodiments, the conjugate linker includes a chain structure such as a hydrocarbyl chain or an oligomer of repeating units such as ethylene glycol, a nucleoside, or an amino acid unit.
[0361] In certain embodiments, the conjugate linker comprises one or more groups selected from alkyl, amino, oxo, amide, disulfide, polyethylene glycol, ether, thioether, and hydroxylamino. In certain such embodiments, the conjugate linker comprises groups selected from alkyl, amino, oxo, amide, and ether groups. In certain embodiments, the conjugate linker comprises groups selected from alkyl and amide groups. In certain embodiments, the conjugate linker comprises groups selected from alkyl and ether groups. In certain embodiments, the conjugate linker comprises at least one phosphorus moiety. In certain embodiments, the conjugate linker comprises at least one phosphate group. In certain embodiments, the conjugate linker comprises at least one neutral bonding group.
[0362] In certain embodiments, conjugate linkers, for example, the conjugate linkers described herein, are known to be useful for attaching conjugate groups to difunctional bonding moieties, such as parent compounds, such as oligonucleotides provided herein. Generally, a difunctional bonding moiety comprises at least two functional groups. One functional group is selected to bond to a specific site of the compound, and the other is selected to bond to a conjugate group. Examples of functional groups used in a difunctional bonding moiety include, but are not limited to, electrophiles for reacting with nucleophiles and nucleophiles for reacting with electrophiles. In certain embodiments, the difunctional bonding moiety comprises one or more groups selected from amino, hydroxyl, carboxylic acid, thiol, alkyl, alkenyl, and alkynyl groups.
[0363] Examples of conjugate linkers include, but are not limited to, pyrrolidine, 8-amino-3,6-dioxaoctanoic acid (ADO), succinimidyl 4-(N-meleiimidomethyl)cyclohexane-1-carboxylate (SMCC), and 6-aminohexanoic acid (AHEX or AHA). Other conjugate linkers include, but are not limited to, substituted or unsubstituted C1-C11. 10 Alkyl, substituted, or unsubstituted C2-C 10 Alkenyl or substituted or unsubstituted C2-C 10 Examples of alkynyl substituents include, but are not limited to, hydroxyl, amino, alkoxy, carboxy, benzyl, phenyl, nitro, thiol, thioalkoxy, halogen, alkyl, aryl, alkenyl, and alkynyl substituents.
[0364] In certain embodiments, the conjugate linker contains 1 to 10 linker-nucleosides. In certain embodiments, such linker-nucleosides are modified nucleosides. In certain embodiments, such linker-nucleosides contain a modified sugar moiety. In certain embodiments, the linker-nucleosides are unmodified. In certain embodiments, the linker-nucleosides optionally contain a protected heterocyclic base selected from purines, substituted purines, pyrimidines, or substituted pyrimidines. In certain embodiments, the cleavable moiety is a nucleoside selected from uracil, thymine, cytosine, 4-N-benzoylcytosine, 5-methylcytosine, 4-N-benzoyl-5-methylcytosine, adenine, 6-N-benzoyladenine, guanine, and 2-N-isobutyrylguanine. Generally, it is desirable that the linker-nucleosides be cleaved from the compound after reaching the target tissue. Therefore, linker-nucleosides are generally bonded to each other via cleavable bonds and to the rest of the compound. In certain embodiments, such cleavable bonds are phosphodiester bonds.
[0365] In this specification, linker nucleosides are not considered part of oligonucleotides. Therefore, in embodiments where a compound comprises a specific number or range of linked nucleosides and / or an oligonucleotide with a specific percentage complementarity to a reference nucleic acid, and the compound also comprises a conjugate group containing a conjugate linker with linker nucleosides, the linker nucleosides are not counted toward the length of the oligonucleotide and are not used to determine the percentage complementarity of the oligonucleotide to the reference nucleic acid. For example, a compound may comprise (1) a modified oligonucleotide consisting of 8 to 30 nucleosides and (2) a conjugate group containing 1 to 10 linker nucleosides consecutive to the nucleosides of the modified oligonucleotide. The total number of consecutive linked nucleosides in such a compound may exceed 30. Alternatively, a compound may comprise a modified oligonucleotide consisting of 8 to 30 nucleosides and not include a conjugate group. The total number of consecutive linked nucleosides in such a compound may be 30 or less. Unless otherwise indicated, a conjugate linker contains 10 or fewer linker-nucleosides. In certain embodiments, a conjugate linker contains 5 or fewer linker-nucleosides. In certain embodiments, a conjugate linker contains 3 or fewer linker-nucleosides. In certain embodiments, a conjugate linker contains 2 or fewer linker-nucleosides. In certain embodiments, a conjugate linker contains 1 or fewer linker-nucleosides.
[0366] In certain embodiments, it is desirable that the conjugate group be cleaved from the oligonucleotide. For example, in certain circumstances, a compound containing a particular conjugate moiety is better absorbed by a particular cell type, but when the compound is absorbed, it is desirable that the conjugate group be cleaved to deconjugate or release the parent oligonucleotide. Therefore, a particular conjugate may generally contain one or more cleavable moieties within the conjugate linker. In certain embodiments, the cleavable moiety is a cleavable bond. In certain embodiments, the cleavable moiety is an atomic group containing at least one cleavable bond. In certain embodiments, the cleavable moiety contains an atomic group having one, two, three, four, or five or more cleavable bonds. In certain embodiments, the cleavable moiety is selectively cleaved within an intracellular cell or an intracellular compartment such as a lysosome. In certain embodiments, the cleavable moiety is selectively cleaved by an endogenous enzyme such as a nuclease.
[0367] In certain embodiments, the cleavable bond is selected from amides, esters, ethers, one or both phosphodiesters, phosphate esters, carbamates, or disulfides. In certain embodiments, the cleavable bond is one or both esters of a phosphodiester. In certain embodiments, the cleavable moiety comprises a phosphate or a phosphodiester. In certain embodiments, the cleavable moiety is a phosphate bond between an oligonucleotide and a conjugate moiety or conjugate group.
[0368] In certain embodiments, the cleavable moiety comprises or consists of one or more linker-nucleosides. In certain such embodiments, one or more linker-nucleosides are bonded to each other and / or to the rest of the compound via cleavable bonds. In certain embodiments, such cleavable bonds are unmodified phosphodiester bonds. In certain embodiments, the cleavable moiety is a 2'-deoxynucleoside attached to either the 3' or 5'-terminal nucleoside of the oligonucleotide by phosphate-nucleoside bonds and covalently bonded to the conjugated linker or the rest of the conjugated moiety by phosphate or phosphorothioate bonds. In certain such embodiments, the cleavable moiety is 2'-deoxyadenosine.

Thus, nucleic acid sequences provided herein, including, but not limited to, those included in the sequence list, are intended to encompass nucleic acids, including, but not limited to, any combination of natural or modified RNA and / or DNA, including nucleic acids having such modified nucleic acid bases. As further examples, and without limitation, the oligomeric compounds having the nucleic acid base sequence "ATCGATCG" include any oligomeric compounds having such a nucleic acid base sequence, whether modified or unmodified, and these oligomeric compounds include, but are not limited to, compounds containing RNA bases such as those having the sequence "AUCGAUCG", compounds containing several DNA bases and several RNA bases such as "AUCGATCG", and oligomeric compounds having other modified nucleic acid bases such as "ATmCGAUCG" (where mC represents a cytosine base with a methyl group at position 5).
[0423] The compounds described herein include (R) or (S), such as α or β in the case of sugar anomers or (D) or (L) in the case of amino acids. The compounds provided herein include all such possible isomers, including their racemic and optically pure forms, unless otherwise specified. Similarly, all cis- and trans-isomers as well as tautomers are included. The compounds described herein include chirally pure or enriched mixtures and racemic mixtures. For example, oligonucleotides having multiple phosphorothioate internucleoside linkages include such compounds where the chirality of the phosphorothioate internucleoside linkages is regulated or random.
[0424] Unless otherwise indicated, any compound containing an oligomeric compound described herein includes its pharmaceutically acceptable salts.
[0425] The compounds described herein include variations in which one or more atoms are replaced with non-radioactive or radioactive isotopes of the indicated element. For example, compounds herein containing a hydrogen atom include all possible deuterium substitutions of each 1 H hydrogen atom. Isotope substitutions included by the compounds herein include, but are not limited to, 1 in place of 2 H or 3 H, 12 in place of 13 C or 14 C, 14 in place of 15 N, 16 in place of 17 O or 18 O and 32 in place of 33 S, 34 S, 35 S or 36 S.
Examples
[0426] Example 1: Preparation of MALAT1-targeting antisense oligonucleotide (ASO) conjugated with GLP-1 peptide. A method for preparing a conjugated modified oligonucleotide containing GLP-1 conjugated at the 5' position via a 3-mercaptopropionate linker.
[0427] Unless otherwise stated, all reagents and solutions used in the synthesis of oligomeric compounds are purchased from commercial sources. Standard phosphoramidite construction blocks and solid supports are used for incorporating nucleoside residues, for example, those containing T, A, G, and mC residues. A 0.1 M solution of phosphoramidite in anhydrous acetonitrile was used for 2'-deoxyribonucleosides, cEt BNA nucleosides, and suitably protected 6-aminohexanols. [ka] 5'-Hexylamino-modified oligonucleotide (ISIS 786434) (nucleic acid sequence: TCAGCATTCTAATAGCAGC (SEQ ID NO: 38)) was synthesized and purified using a standard solid-phase oligonucleotide procedure. The 5' end of the modified oligonucleotide contains a hexamethylene linker and a terminal amine. Compound 1 (3-(2-pyridyldithiopropionic acid N-hydroxysuccinimide ester) was obtained from Chem-Impex (cat#11566). Approximately 6 μmol of the modified oligonucleotide was dissolved in 125 μL sodium phosphate buffer, pH 8, and 12 μmol of compound 1 was dissolved in DMF. The solution of compound 1 was added dropwise to the modified oligonucleotide solution and the reaction was allowed to proceed at room temperature. The reaction was completed after 2-3 hours, and product 2 was HPLC on Source 30Q resin using buffer A 100 mM NH4OAc / 30%ACN / H2O and buffer B 100 mM NH4OAc / 30%ACN / H2O + 1.5M The product was purified using NaBr and desalted by HPLC on a reverse-phase column. The product fraction was concentrated and stored at -20°C.
[0428] Compound 2 was used as a starting material for the reaction with the GLP-1 peptide HisAibGluGlyThrPheThrSerAspValSerSerTyrLeuGluGluGlnAlaAlaLysGluPheIleAlaTrpLeuValLysGlyGlyProSerSerAlaProProProSerCys-NH2 (SEQ ID NO: 22), which was synthesized by standard solid-phase peptide synthesis. Aib is 2-aminoisobutyric acid. Compound 2 was dissolved in degassed water, and 0.1 M NaHCO3 was added to adjust the pH to approximately 8.0. The GLP-1 peptide was dissolved in 50 / 50 0.1 M NaHCO3 (pH 8):DMF (dimethylformamide). The peptide solution was added to compound 2 in small amounts (30% of the total volume each time) at 5-minute intervals. After approximately 1 hour, the reaction mixture was diluted with water (5 times the volume of the reaction solution, V / V), and the product was purified by HPLC on a Source 30Q resin using buffer A 100mM NH4OAc / 30%ACN / H2O and buffer B 100mM NH4OAc / 30%ACN / H2O + 1.5M NaBr. The product fraction was desalted by HPLC on a reversed-phase column to obtain ISIS 816385.
[0429] Example 2: Preparation of MALAT1-targeting antisense oligonucleotides (ASOs) conjugated with GLP-1 peptide. A method for preparing a conjugated oligonucleotide containing GLP-1 conjugated at the 5' position to a C-terminal penicillamine via a 3-mercaptopropionate linker. [ka] Compound 2 was synthesized as in Example 1 and used as a starting material for a reaction with the GLP-1 peptide: HisAibGluGlyThrPheThrSerAspValSerSerTyrLeuGluGluGlnAlaAlaLysGluPheIleAlaTrpLeuValLysGlyGlyProSerSerAlaProProProSerPen-NH2 (SEQ ID NO: 23), which was synthesized by standard solid-phase peptide synthesis. Aib is 2-aminoisobutyric acid and Pen is penicillamine. Compound 2 was dissolved in degassed water and 0.1 M NaHCO3 was added to adjust the pH to approximately 8.0. The GLP-1 peptide was dissolved in degassed water. The solution of Compound 2 and the peptide solution were mixed by gentle vortexing and the pH was checked. 0.1 M NaHCO3 was added to adjust the pH to approximately 7.5. After about 2 hours, additional peptide was added and NaHCO3 was added to adjust the pH upwards. The reaction was carried out at 4°C for approximately 65 hours, and the product was purified by HPLC as described in Example 1.
[0430] Example 3: Preparation of FOXO1-targeting antisense oligonucleotides (ASOs) conjugated with GLP-1 peptide. A method for preparing a conjugated modified oligonucleotide containing GLP-1 conjugated at the 5' position via a 3-mercaptopropionate linker.
[0431] ION 913193, a 5'-GLP-1 peptide conjugate ASO targeting FOXO1, was prepared starting from a 5'-hexylamino modified oligonucleotide (ION 913192) (nucleic acid sequence: TCATCTTCTTAAAATACCC (SEQ ID NO: 59)) having chemical modifications: Tdo mCdo Ado Tks mCks Tds Tds mCds Tds Tds Ads Ads Ads Aks Tes Aks mCes mCks mCk (k=cEt; d=2'-deoxy; e=2'-MOE; mC=5-methylcytosine; o=phosphodiester; and s=phosphorothioate), following the procedure of Example 1.
[0432] A control 5'-GLP-1 peptide conjugate ASO having a nucleic acid sequence mismatched to ION 913195 and FOXO1 was prepared starting from a 5'-hexylamino modified oligonucleotide (ION 913194) (nucleic acid sequence: TCAGGCCAATACGCCGTCA (SEQ ID NO: 60)) having chemical modifications: Tdo mCdo Ado Gks Gks mCks mCds Ads Ads Tds Ads mCds Gds mCds mCds Gds Tks mCks Ak (k=cEt;d=2'-deoxy;e=2'-MOE;mC=5-methylcytosine;o=phosphodiester;and s=phosphorothioate), following the procedure of Example 1.
[0433] Example 4: Preparation of insulin-targeting antisense oligonucleotides (ASOs) conjugated with GLP-1 peptide A method for preparing a conjugated oligonucleotide containing GLP-1 conjugated at the 5' position via a mercaptopropionate linker.
[0434] ION 919553, an insulin-targeting 5'-GLP-1 peptide conjugate ASO, was prepared starting from a 5'-hexylamino modified oligonucleotide (ION 919553) (nucleic acid sequence: TCAGCCAAGGTCTGAAGGTCACC (SEQ ID NO: 61)) having chemical modifications: Tdo mCdo Ado Ges mCes mCes Aes Aes Gds Gds Tds mCds Tds Gds Ads Ads Gds Gds Tes mCes Aes mCes mCe (k=cEt;d=2'-deoxy;e=2'-MOE;mC=5-methylcytosine;o=phosphodiester;and s=phosphorothioate) and following the procedure of Example 1.
[0435] Example 5: Preparation of MALAT1-targeting antisense oligonucleotide (ASO) conjugated with GLP-1 peptide ION 951976 (nucleic acid sequence: GCTGCTATTAGAATGC (SEQ ID NO: 62)) having chemical modifications: Ges mCeo Tdo Gdo mCdo Tdo Ado Tdo Tdo Tdo Ado Ado Gdo Ado Ado Tds Ges mCe (d=2'-deoxy; e=2'-MOE; mC=5-methylcytosine; o=phosphodiester; and s=phosphorothioate) was synthesized and purified using a standard solid-phase oligonucleotide procedure. ISIS 816385 described in Example 1 was hybridized with ION 951976 to produce a double helix of two oligonucleotides.
[0436] Example 6: In vivo targeting of pancreatic β-islet cells using GLP-1 peptide conjugate ASO Research 1 To determine whether GLP-1 peptide conjugation to ASO increases ASO delivery to the pancreas, male C57BL / 6 mice fed solid diet received intravenous injections of either 3-10-3 cEt ASO (ISIS 556089) (nucleotide sequence: GCATTCTAATAGCAGC) (SEQ ID NO: 63), which targets mouse MALAT1, or GLP-1 conjugated MALAT1 ASO (ISIS 816385) as described in Example 1, at concentrations of 1.8, 0.6, or 0.2 μmol / kg. Tissue samples were collected 72 hours after the final injection to evaluate compound delivery and efficacy.
[0437] MALAT1 expression was detected using the QuantiGene ViewRNA tissue assay (Affymetrix, cat.No.QVT0011). Species-specific MALAT1 probes were purchased from Affymetrix (cat.No.VB-11110-01 / mouse; VF1-13963 / monkey). Briefly, mouse tissue was fixed in 10% neutral buffered formalin, embedded in paraffin, and cut into 4 mm sections. After deparaffinization, the tissue slides were boiled in Affymetrix pretreatment solution for 10-30 minutes, and then treated with protease at 40°C for 10-40 minutes depending on the tissue. The MALAT1 RNA probe was used at a 1:40 dilution and incubated with the sample at 40°C for 120 minutes. After washing, the MALAT1 RNA / probe complex was hybridized with the preamplifier, amplifier, and AP oligonucleotide at 40°C for 25, 15, and 15 minutes, respectively. After washing in PBS to remove free AP oligonucleotides, the slides were incubated with Fast Red substrate at room temperature for 30 minutes. Tissue images were obtained using an Aperio scanner. Hung et al., 2013 Nuc Acid Ther. 369-78.
[0438] In-situ hybridization analysis showed that GLP-1 peptide conjugation reduced MALAT1 staining in β-islet cells but not in pancreatic acinar cells. ASO staining of pancreatic sections showed that GLP-1 conjugate improved efficacy by increasing ASO delivery to tissue. Mice treated with GLP-1 conjugated MALAT1 ASO (ISIS 816385) showed reduced MALAT1 expression in pancreatic β-islet cells, but not in mice treated with unconjugated MALAT1 ASO (ISIS 556089). Mice treated with various doses of ISIS 816385 showed reduced MALAT1 expression in pancreatic β-islet cells. Mice treated with GLP-1 conjugated MALAT1 ASO (ISIS 816385) showed ASO accumulation in pancreatic β-islet cells, but mice treated with unconjugated MALAT1 ASO (ISIS 556089) did not. GLP-1 conjugated MALAT1 ASO (ISIS 816385) accumulated in a dose-dependent manner in pancreatic β-islet cells of treated mice.
[0439] Research 2 To determine the dose-response relationship between GLP-1 conjugated MALAT1 ASO (ISIS 816385) described in Example 1 and pancreatic MALAT1 expression, male C57BL / 6 mice fed solid feed received a single intravenous injection of either ISIS 816385 or unconjugated MALAT1 ASO (ISIS 556089) at concentrations of 0.2, 0.06, and 0.02 μmol / kg.
[0440] MALAT1 expression was detected using the QuantiGene ViewRNA tissue assay described above.
[0441] In-situ hybridization analysis showed that GLP-1 peptide conjugation reduced MALAT1 staining in pancreatic β-islet cells at doses of 0.2 μmol / kg and 0.06 μmol / kg. No observable effect of ISIS 816385 or ISIS 556089 in the liver was observed at either dose.
[0442] Example 7: Antisense inhibition of MALAT1 and FOXO1 using GLP-1 peptide conjugate antisense oligonucleotides in HEK293 cells overexpressing the human GLP-1 receptor. Antisense oligonucleotides designed to target MALAT1 and FOXO1 were conjugated to a glucagon-like peptide-1 receptor peptide agonist (GLP-1 peptide), and their effects on human target gene expression were tested using the HEK293 cell line (hGLP1R-HEK), which exhibits stable constitutive expression of the human GLP-1 receptor.
[0443] hGLP1R-HEK cell lines were generated by expressing hGLP1R in Flp-IN(trademark)293 cells. Cultured hGLP1R-HEK cells were seeded at a density of 30,000 cells / well in 96-well plates and conditioned for approximately 24 hours with physiological saline, 100 nM, or 10 μM of the following: MALAT1-targeting non-conjugate parent antisense oligonucleotide ISIS 556089 or FOXO1-targeting ISIS 776102 (nucleic acid sequence: TCTTCTTAAAATACCC) (SEQ ID NO: 64), or the corresponding GLP-1 peptide-conjugate antisense oligonucleotide (MALAT1-targeting ISIS 816385 or FOXO1-targeting ION 913193). After the processing period, cells were harvested, mRNA was isolated, and measured using a nanadrop UV-Vis spectrophotometer to adjust for total RNA content. MALAT1 or FOXO1 mRNA levels were measured by quantitative real-time PCR and normalized to the mRNA level of the housekeeping gene (RPLP0) in the same sample. Human MALAT1 mRNA levels were measured using gene expression assay HS00273907, and FOXO1 mRNA levels were measured using assay Hs01054576 (Applied Biosystems). The mRNA level of the housekeeping gene RPLP0 was measured using a primer-probe set with the forward sequence CCATTCTATCATCAACGGGTACAA (SEQ ID NO: 66) and the reverse sequence AGCAAGTGGGAAGGTGTAATCC (SEQ ID NO: 67).
[0444] The data are shown as percentage inhibition of MALAT1 or FOXO1 mRNA compared to untreated control cells. White symbols represent treatment with parental antisense oligonucleotides, while black symbols represent treatment with antisense nucleotides conjugated to the GLP-1 peptide. As shown in Figure 1, in the hGLP1R-HEK cell line, antisense oligonucleotides conjugated to the GLP-1 peptide inhibited MALAT1 or FOXO1 mRNA more potently than parental antisense oligonucleotides.
[0445] Example 8: Dose-dependent antisense inhibition of MALAT1 after treatment with unconjugated parent or GLP-1 peptide conjugated antisense oligonucleotides in wild-type and HEK293 cells overexpressing human GPR40 or GLP-1 receptor. The MALAT1 antisense oligonucleotide from Example 7 was further tested at various concentrations in wild-type, hGPR40, and hGLP1R-HEK cells.
[0446] Cultured hGLP1R-HEK, wild-type HEK293 (WT HEK293), or cells expressing the hGPR40 receptor were seeded at a density of 30,000 cells / well in 96-well plates and treated with 0.001, 0.003, 0.01, 0.03, 0.1, 0.3, 1, 3, 10, or 30 μM antisense oligonucleotides for approximately 24 hours (concentrations are shown in Figure 2). After the treatment period, cells were harvested, mRNA was isolated, and MALAT1 mRNA levels were measured by quantitative real-time PCR using the primer-probe set described herein (Example 7). Data are shown as MALAT1 mRNA levels normalized to the housekeeping gene (RPLP0). White symbols represent treatment with a parent antisense oligonucleotide (ISIS 556089) that targets MALAT1, while black symbols represent treatment with the same antisense nucleotide (ISIS 816385) conjugated to a GLP-1 peptide.
[0447] The half-number inhibitory concentrations (IC50) of each oligonucleotide are shown in the table below.
[0448] [Table 1]
[0449] When conjugated to a GLP-1 peptide agonist, antisense oligonucleotides inhibited MALAT1 gene expression 40-fold more potently in the hGLP1R-HEK cell line (Figure 2A), but did not inhibit it in the same way in WT HEK293 (Figure 2B) or hGPR40-HEK cell line (Figure 2C).
[0450] Example 9: Antisense inhibition of MALAT1 and FOXO1 in mouse primary islets of Langerhans after treatment with unconjugated parent or GLP-1 peptide-conjugated antisense oligonucleotides. Antisense oligonucleotides targeting MALAT1 and FOXO1 were further tested in the mouse primary islets of Langerhans for their ability to reduce gene expression.
[0451] Pancreatic islets were isolated by collagenase digestion of the pancreas collected from blood-extracted 12-15 week old female C57BL / 6Crl mice. The islets were maintained in tissue culture until use. The islets were separated into single cells by shaking in a medium containing a low extracellular calcium concentration. 10-20 intact or isolated islets were seeded in plastic petri dishes and treated with 10 μM antisense oligonucleotides for approximately 24 hours. After the treatment period, the cells were harvested, RNA was isolated, and adjusted for total RNA content by RIBOGREEN®. MALAT1 or FOXO1 mRNA levels were measured by quantitative real-time PCR. Mouse Malat1 mRNA levels were measured using Applied Biosystems' gene expression assay Mm01227912_s1, while mouse FOXO1 mRNA levels were measured using a primer-probe set with the forward sequence CAGTCACATACGGCCAATCC (SEQ ID NO: 68), the reverse sequence CGTAACTTGATTTGCTGTCCTGAA (SEQ ID NO: 69), and the probe sequence TGAGCCCTTTGCCCCAGATGCCTAT (SEQ ID NO: 70). All data were normalized to the mRNA levels of the housekeeping gene (RPLP0) in the same sample, measured using a primer-probe set with the forward sequence GAGGAATCAGATGAGGATATGGGA (SEQ ID NO: 71), the reverse sequence AAGCAGGCTGACTTGGTTGC (SEQ ID NO: 72), and the probe sequence TCGGTCTCTTCGACTAATCCCGCCAA (SEQ ID NO: 73).
[0452] Figure 3 shows data for the levels of MALAT1 or FOXO1 mRNA against the housekeeping gene (RPLP0). Star symbols represent no treatment for MALAT1 (ISIS 816385) or FOXO1 (ISIS 919193), white circles represent treatment with parental unconjugated antisense oligonucleotides (ISIS 556089 targeting MALAT1 or ISIS 776102 targeting FOXO1), white squares represent treatment with a scrambled FOXO1 antisense oligonucleotide sequence conjugated to a GLP1 peptide (ION 913195), while black symbols represent treatment with an antisense oligonucleotide conjugated to a GLP1 peptide.
[0453] Example 10: Antisense inhibition of FOXO1 and reduction of Foxo1 protein in mouse primary islets of Langerhans after treatment with unconjugated parent and GLP-1 peptide-conjugated antisense oligonucleotides. We tested antisense oligonucleotides targeting FOXO1 for their ability to reduce protein levels in the mouse primary islets of Langerhans.
[0454] Pancreatic islets were isolated by collagenase digestion of the pancreas collected from euthanized 12-15 week old female B6.Cg-Lepob / J mice and maintained in tissue culture until use. 150 intact islets were placed in plastic petri dishes and treated with 1 μM antisense oligonucleotide for 3 hours every 24 hours, and harvested after approximately 24, 48, or 96 total treatment times, respectively. After the treatment period, the islets were harvested, and half of the islets were used to measure FOXO1 mRNA levels as described herein (Example 9). Half of the islets were homogenized in M-PER protein extraction reagent (Thermo Scientific) containing a protease inhibitor cocktail (Complete Mini and phosphoSTOP, Roche Diagnostics). The protein content of the lysates was quantified using BCA assay reagent (Pierce). FoxO1 protein was detected by Western blot analysis using the primary antibody C29H4 (Cell Signalling, #2880) against FoxO1. α-tubulin was measured using Sigma's primary antibody (#T6074) as a control of the sample loaded onto the gel. For the anti-FoxO1 antibody, the secondary antibody was HRP-conjugate polyclonal goat anti-rabbit P0448 (DAKO), and for the anti-α-tubulin antibody, the secondary antibody was HRP-conjugate polyclonal goat anti-mouse P0447 (DAKO). Enhanced chemiluminescence reagent (Pierce) was used for detection.
[0455] Inhibition of FOXO1 mRNA is shown as FOXO1 mRNA against housekeeping genes, expressed as a percentage of untreated cells in the table below. This shows a slight decrease in mRNA with unconjugated antisense oligonucleotide (ISIS 776102) and a decrease of over 70% with GLP-1 conjugated antisense oligonucleotide (ION 913193).
[0456] [Table 2]
[0457] Western blotting showed a decrease in FoxO1 protein levels measured in pancreases treated with vehicle or antisense oligonucleotides for 96 hours. Protein levels were quantified by measuring the intensity of bands on the gel, normalized to the intensity of α-tubulin, and expressed as a percentage of vehicle-treated islets. FoxO1 protein levels were set to 100% in vehicle-treated islets. In contrast, FoxO1 protein levels were 5% in GLP-1-FOXO1 ASO-treated islets.
[0458] Example 11: Incorporation of antisense oligonucleotides into in situ islets of Langerhans in the pancreas after administration of unconjugated parent or GLP-1 peptide-conjugated antisense oligonucleotides targeting MALAT1 to C57BL / 6Crl mice. Unconjugated parent and GLP-1 peptide-conjugated antisense oligonucleotides targeting MALAT1 were further tested in vivo to evaluate the uptake of antisense oligonucleotides into pancreatic islets after intravenous or subcutaneous administration of the treated material.
[0459] Female C57BL / 6Crl mice were assigned to five treatment groups. Two groups received either a vehicle (saline) or 2 μmol / kg GLP-1 conjugate antisense oligonucleotide (ISIS 816385) via tail vein injection. Three groups received either saline, 2 μmol / kg unconjugate parental antisense oligonucleotide (ISIS 556089), or 2 μmol / kg GLP-1 conjugate antisense oligonucleotide (ISIS 816385) via subcutaneous administration twice weekly for two weeks. All animals were sacrificed approximately 72 hours after the final dose, and the pancreas was collected for ex vivo analysis by immunohistochemical examination of antisense oligonucleotide uptake.
[0460] All tissues were fixed in 10% neutral buffered formalin at room temperature for 32 hours. After fixation, samples were dehydrated using a standard series of ethanols followed by xylene and embedded in paraffin. Tissue sections were cut to a thickness of 4 μm, placed on superfrost® Plus slides, and baked in a drying oven at 60°C for 1 hour. Immunohistochemical testing for antisense oligonucleotide detection was performed in a Ventana Discovery XT immunohistochemistry machine (Ventana Medical System, Inc.) according to manufacturer recommendations, with all reagents being Ventana products (Roche Diagnostics, Basel, Switzerland). Protease 1 was used as the enzyme antigen retrieved, and the incubation was 8 minutes. After adding an antibody blocker for 4 minutes to reduce background, rabbit anti-ASO 2.5 was added at 37°C for 1 hour (dilution 1:5000, Ionis Pharmaceuticals). For secondary detection, OmiMap anti-rabbit HRP was incubated for 16 minutes, followed by color detection using the DISCOVERY ChromoMap DAB kit (RUO). The slides were counterstained with hematoxylin for 4 minutes, and then blued for 4 minutes. The stained slides were analyzed under a standard bright-field microscope.
[0461] Antisense oligonucleotides were detected in the pancreatic islets of Langerhans of animals treated with ISIS 816385, either subcutaneously or intravenously. Oligonucleotides were not detected in the islets of Langerhans of animals subcutaneously treated with ISIS 556089.
[0462] Example 12: Antisense inhibition of MALAT1 in the in situ islets of Langerhans in the pancreas after administration of unconjugated parent or GLP-1 peptide-conjugated antisense oligonucleotide in C57BL / 6Crl mice. Unconjugated parent and GLP-1 peptide-conjugated antisense oligonucleotides against MALAT1 were further tested in vivo to evaluate antisense inhibition of MALAT1 in the pancreas after intravenous or subcutaneous administration of the treatment.
[0463] Female C57BL / 6Crl mice were assigned to five treatment groups as described herein (Example 11). Animals were sacrificed approximately 72 hours after the final dose, and the pancreas was harvested for ex vivo analysis of MALAT1 expression by in situ hybridization.
[0464] Tissue was prepared as described herein (Example 11). In-situ mRNA amplification and labeling processes were performed on the Ventana Discovery ULTRA, Automated ISH platform (Ventana Medical System, Inc.) using the RNAscope® VS assay based on Advanced Cell Diagnostics (ACD). A custom-ordered probe was obtained from ACD for the detection of MALAT1 mRNA, and various parameters were tested to optimize a novel RNAscope method for ISH. The signal was amplified using multiple steps, followed by probe labeling and detection using the RNAscope® 2.5 VS Reagent Kit-RED. Stained slides were analyzed under a standard bright-field microscope.
[0465] MALAT1 expression was decreased in the pancreatic islets of Langerhans of animals treated subcutaneously or intravenously with GLP-1 peptide-conjugated antisense oligonucleotide (ISIS 816385), but not in exocrine tissues. MALAT1 expression was not decreased in animals subcutaneously treated with unconjugated parental antisense oligonucleotide (ISIS 556089).
[0466] Example 13: Uptake of antisense oligonucleotides into the liver 72 hours after administration of unconjugated parent or GLP-1 peptide-conjugated antisense oligonucleotides targeting MALAT1 to C57BL / 6Crl mice. Unconjugated parent and GLP-1 peptide-conjugated antisense oligonucleotides to MALAT1 were further tested in vivo to evaluate the hepatic uptake of antisense oligonucleotides via either intravenous or subcutaneous administration.
[0467] The animals were assigned to the treatment as described herein (Example 11). All animals were sacrificed approximately 72 hours after the final dose, and the pancreas was recovered for ex vivo analysis by immunohistochemical examination of antisense oligonucleotide uptake.
[0468] Tissue was prepared and immunohistochemical analysis was performed as described herein (Example 12).
[0469] Antisense oligonucleotides were detected in hepatic parenchymal cells and Kupffer cells of the livers of animals treated with both ISIS 816385 and ISIS 556089, administered either subcutaneously or intravenously as shown.
[0470] Example 14: Antisense inhibition of MALAT1 in the liver after administration of unconjugated parent or GLP-1 peptide-conjugated antisense oligonucleotide in C57BL / 6Crl mice Unconjugated parent (ISIS 556089) and GLP-1 peptide-conjugated antisense oligonucleotides against MALAT1 were further tested in vivo to evaluate antisense inhibition of MALAT1 in the liver via intravenous and subcutaneous administration routes.
[0471] Female C57BL / 6Crl mice were assigned to five treatment groups as described herein (Example 13). All animals were sacrificed approximately 72 hours after the end of treatment, and the livers were collected for ex vivo analysis of MALAT1 expression by in situ hybridization.
[0472] Tissue was prepared and in situ hybridization was performed as described herein (Example 12).
[0473] Hepatic MALAT1 expression was reduced in hepatic parenchymal cells of animals treated with ISIS 816385 to a higher degree than in hepatic parenchymal cells of animals treated with ISIS 556089 via subcutaneous administration. Hepatic MALAT1 was also reduced compared to vehicle controls in animals administered ISIS 816385 intravenously.
[0474] Example 15: Dose-dependent antisense inhibition of MALAT1 in isolated islets of Langerhans and liver 72 hours after administration of a single dose of unconjugated parental and GLP-1 peptide-conjugated antisense oligonucleotides in C57BL / 6Crl mice. Unconjugated parent molecules and GLP-1 peptide-conjugated antisense oligonucleotides were further tested in vivo to evaluate the efficacy of MALAT1 antisense inhibition in isolated pancreatic islets of Langerhans in the liver 72 hours after a single subcutaneous administration.
[0475] Female C57BL / 6Crl mice were assigned to eight treatment groups, receiving a single subcutaneous injection of either vehicle, 0.01 μmol / kg, 0.03 μmol / kg, 0.1 μmol / kg, or 1 μmol / kg ISIS 816385, while the other three treatment groups received 0.01 μmol / kg, 0.1 μmol / kg, or 1 μmol / kg ISIS 556089. All animals were sacrificed 72 hours after the final dose. For mRNA analysis, liver samples were collected and pancreatic islets isolated as described herein (Example 9). MALAT1 mRNA levels were quantified as described herein (Example 9) and expressed as a percentage of vehicle-treated animals (control).
[0476] No significant antisense inhibition of MALAT1 was observed in the liver or in the islets of Langerhans from animals treated with the parent antisense oligonucleotide (ISIS 556089) in any of the treatment groups. GLP-1 peptide-conjugated antisense oligonucleotides dose-dependently inhibited MALAT1 mRNA levels at an estimated ED50 of 0.07 μmol / kg.
[0477] Example 16: Dose-dependent antisense inhibition of FOXO1 in isolated islets of Langerhans and liver 72 hours after administration of a single dose of unconjugated parental and GLP-1 peptide-conjugated antisense oligonucleotides in C57BL / 6Crl mice. Unconjugated parent molecules and GLP-1 peptide-conjugated antisense oligonucleotides were further tested in vivo to evaluate the efficacy of FOXO1 antisense inhibition in isolated pancreatic islets of Langerhans in the liver 72 hours after single-dose subcutaneous administration.
[0478] Female C57BL / 6Crl mice were assigned to seven treatment groups, receiving a single subcutaneous injection of either vehicle, 0.01 μmol / kg, 0.03 μmol / kg, 0.1 μmol / kg, or 1 μmol / kg ION 913193, while two treatment groups received either 0.01 μmol / kg or 1 μmol / kg ISIS 776102. All animals were sacrificed 72 hours after the final dose. For mRNA analysis, liver samples were collected and pancreatic islets isolated as described herein (Example 9). FOXO1 mRNA levels were quantified as described herein (Example 9) and expressed as a percentage of vehicle-treated animals (control).
[0479] No significant antisense inhibition of FOXO1 in the liver or islets of Langerhans was observed in any of the treatment groups treated with the parent antisense oligonucleotide (ISIS 776102). GLP-1 peptide-conjugated antisense oligonucleotides dose-dependently inhibited FOXO1 mRNA levels at an estimated ED50 of 0.04 μmol / kg.
[0480] Example 17: Antisense inhibition of FOXO1 in isolated islets of Langerhans and liver 6 weeks after repeated administration of unconjugated parent or GLP-1 peptide-conjugated antisense oligonucleotides to ob / ob mice. Unconjugated parent and GLP-1 peptide-conjugated antisense oligonucleotides were further tested in vivo to evaluate the efficacy of FOXO1 antisense inhibition in isolated pancreatic islets of Langerhans in the liver 6 weeks after treatment.
[0481] Male ob / ob mice (B6.V-Lepob / OlaHsd, Harlan) were assigned to five treatment groups and received either vehicle, 0.1 μmol / kg ISIS 776102, 0.1 μmol / kg ION 913195, 0.03 μmol / kg ION 913193, or 1 μmol / kg ION 913193. All animals were treated once a week for 6 weeks. Approximately 120 hours after the final dose, all animals were sacrificed, and liver samples were collected for mRNA analysis as described herein (Example 9), and pancreatic islets were isolated. FOXO1 mRNA levels were quantified as described herein (Example 9), and mRNA levels were normalized to the housekeeping gene (RPLP0) in each sample.
[0482] Significant antisense inhibition of FOXO1 was not observed in the liver or in the islets of Langerhans treated with either the parent antisense oligonucleotide (ISIS 776102) or a scrambled FOXO1 antisense oligonucleotide sequence conjugated with GLP-1 peptide in any of the treatment groups (ION 913195). Animals treated with GLP-1 peptide-conjugated antisense oligonucleotide (ION 913193) showed reduced FOXO1 mRNA levels in isolated islets of Langerhans at both dose levels tested (a 42% mean decrease in FOXO1 mRNA at 0.03 μmol / kg and a 72% mean decrease in FOXO1 mRNA at 0.1 μmol / kg), demonstrating that GLP-1 peptide conjugation enhances antisense inhibition in pancreatic islets of Langerhans in vivo.
[0483] Example 18: Decrease in FoxO1 protein levels in islets of Langerhans isolated from ob / ob mice treated for 6 weeks with unconjugated parent or GLP-1 peptide-conjugated antisense oligonucleotides. Unconjugated parental and GLP-1 peptide-conjugated antisense oligonucleotides were further tested for their ability to reduce FoxO1 protein levels in mouse pancreatic islets of Langerhans isolated from ob / ob mice treated for 6 weeks.
[0484] Male ob / ob mice were assigned to five treatment groups as described herein (Example 17). Approximately 120 hours after the final dose, all animals were sacrificed and the pancreatic islets were isolated as described herein (Example 10) for FoxO1 protein analysis. Random samples were selected from each treatment group and loaded onto each gel so that at least one sample from each treatment group was analyzed on the same gel. FoxO1 protein levels were measured by quantifying the intensity and normalized to α-tubulin levels in the same sample. All samples in each gel were expressed as a percentage of the levels measured in the pancreatic islets of animals receiving ION 913195.
[0485] Foxo1 protein levels in animals treated with ION 913193 decreased by 57% and 81% compared to ION 913195 when treated with 0.03 μmol / kg and 0.1 μmol / kg, respectively, and decreased by 64% and 36% compared to animals treated with 0.1 μmol / kg ISIS 776102.

The 5' end of the modified oligonucleotide contains a hexamethylene linker and a terminal amine. BCN-NHS ester (Mol. Wt 291.11 g / mol, 7441R,8S,9s)-bicyclo(6.1.0)nonano-4-in-9-ylmethyl N-succinimidyl carbonate) was obtained from Aldrich. Approximately 1 g of the modified oligonucleotide was dissolved in 5 mL of sodium tetraborate buffer, pH 8.5. 13.4 mg of the BCN-NHS ester was dissolved in 10 mL of DMSO and added to ASO solution, and stirred at room temperature for 4 hours. The reaction mixture was diluted in 1 M NaCl solution and desalted by HPLC on a reverse-phase column.

The peptide solution was added to the ASO solution and stirred at room temperature for 18 hours. Precipitation was observed after 18 hours, and an additional 1 mL of DMF was added. The reaction was continued for a further 5 hours. The product was purified by HPLC on a SAX column using buffer A 100 mM NH4OAc / 30%ACN / H2O and buffer B 1.5 M NaBr / NH4OAc / 30%ACN / H2O, and desalted by HPLC on a reversed-phase column. The product fraction was collected and lyophilized to obtain the expected conjugated ASO, ION 1071996. [ka]
[0490] Example 21: Antisense inhibition of MALAT1 in mouse primary islets of Langerhans after treatment with non-conjugated parent or GLP-1 peptide-conjugated ASO having various linkers. To determine whether the chemical structure of GLP-1 peptide conjugation to ASO affects ASO delivery into the pancreas, male C57BL / 6 mice received intravenous injections of either ISIS 556089 (parent unconjugated ASO), ISIS 816385 (GLP-1 conjugated ASO with disulfide linker and 5'TCA linker), ION 962963 (GLP-1 conjugated ASO with disulfide linker and no 5' nucleotide spacer) or ION 1071996 (GLP-1 conjugated ASO conjugated via click linker) once weekly at a dose of 0.6 μmol / kg / week for three weeks. Tissue was collected 72 hours after the final injection to evaluate compound delivery and efficacy.
[0491] MALAT1 expression was detected as in Example 6. In-situ hybridization analysis showed that MALAT1 expression in β-islet cells was reduced in mice treated with GLP-1 conjugated ASOs (ISIS 816385, ION 962963, and ION 1071996) compared to saline controls, but not in mice treated with unconjugated parental ASOs (ISIS 556089).
[0492] Example 22: Dose-dependent reduction of MALAT-1 expression in LVX-GLP1R cells HEK cells stably expressing FLAG-tagged GLP1R were generated by infecting them with a lentivirus containing FLAG-tagged GLP1R, produced by transfection of 293T cells using pLVX-IRES-Puro (Clontech Laboratories Inc., Mountainview, CA) containing a FLAG-GLP1R insert. Infected cells were selected with puromycin (2 μg / ml), and receptor expression was then analyzed by Western blotting and immunofluorescence. Cultured GLP1R cells were seeded at a density of 10,000 cells / well and treated with 0.3, 1, 3, 9, 27, 82, 247, 741, 2,222, 6,667, and 20,000 nM modified oligonucleotides for approximately 24 hours.

The peptide solution was slowly added to the ASO solution and stirred at room temperature for 30 minutes. The reaction was monitored by LC-MS and stirring was continued for a further 1 hour. The main fraction was found to be the expected product. The product was diluted with water and kept at 4°C until purified by HPLC on a strong anion exchange column (buffer A = 100 mM ammonium acetate in 30% aqueous acetonitrile solution; buffer B: 1.5 M NaBr in A, 0-60% B in 28 column volume). The fractions containing full-length ASO were pooled together, diluted to a 10% concentration of acetonitrile, and desalted by HPLC on a reverse-phase column (buffer A = 0.1 M sodium chloride, B = water, C = 50% acetonitrile in water). The fractions were pooled together, evaporated, and the expected product was obtained, as confirmed by LC-MS.

A 5'-hexylamino modified oligonucleotide (ISIS 786434) targeting MALAT1 was synthesized on a NittoPhase® HL solid support (115 mg, 47 umol) using an AKTA Oligopilot® synthesizer. A 0.1 M solution of thiol modifier C6 SS amidite (Glen research 10-1936-02, 0.25 g in 3.2525 mL of dry ACN) and N-(4-monomethoxytrityl (MMT))-6-amino-1-hexanol amidite (0.177 g in 3 mL of dry ACN) were conjugated to a solid support supporting Ion 925727 using a standard solid-phase oligonucleotide procedure. The 5'-MMT-protected oligonucleotide was cleaved, precipitated, and purified as previously described herein. The MMT-protected oligonucleotide was dissolved in 50 mL of water and 50 mL of 3 M sodium acetate solution (pH 5.0) and heated at 45°C for 60 minutes. The reaction mixture was cooled from 45°C to 22°C, and the pH was raised to 5.92 by adding 10% v / v 2.0 M buffered sodium acetate solution (pH 7.2). The reaction was thought to stop upon completion of sodium acetate addition. The product was purified by HPLC on a source 30Q resin using buffer A 100 mM NH4OAc / 30%ACN / H2O and buffer B 100 mM NH4OAc / 30%ACN / H2O + 1.5 M NaBr. The pure fraction was desalted on a reverse-phase column by HPLC to obtain the MMT-deprotected oligonucleotide.
[0505] Next, the deprotected oligonucleotide was reacted with 3 eq. of (1R,8S,9s)-bicyclo[6.1.0]nona-4-in-9-ylmethyl N-succinimidyl carbonate (744867 Aldrich) in 1:2 DMSO-sodium tetraborate buffer pH 8.5 at room temperature to obtain 5'-BCN-C6 MALAT1 ASO.

[0507] Example 29: Antisense inhibition of MALAT1 in isolated islets of Langerhans in C57BL / 6Crl mice 72 hours after administration of a single dose of GLP-1 peptide-conjugated antisense oligonucleotides with various linkers. To determine whether the chemistry of GLP-1 peptide conjugation to ASO affects ASO delivery into the pancreas, female C57BL / 6Crl mice received a single subcutaneous injection of 0.01 μmol / kg vehicle (physiological saline), ISIS 816385 (GLP-1 conjugated ASO with a disulfide linker), ION 1071996 (GLP-1 conjugated ASO conjugated via a click linker), ION 1086699 (GLP-1 conjugated ASO conjugated via a maleimide linker), ION 1123118 (GLP-1 conjugated ASO conjugated via a maleimide acid linker), or ION 1123478 (GLP-1 conjugated ASO conjugated via a disulfide-click linker). Islets were isolated 72 hours after subcutaneous administration to evaluate compound delivery and efficacy.
[0508] MALAT1 expression was measured as in Example 9 and expressed as a percentage of the vehicle-treated animals (control), and compared with expression in islets from mice treated with ISIS 816395. qPCR quantification showed that MALAT1 expression in β-islet cells was significantly further reduced in mice treated with GLP-1 conjugated ASO ION 1086699, ION 1123118, and ION 1123478 compared to ISIS 816385, and similarly reduced in mice treated with ION 1071996.

[0510] Example 30: Dose-response antisense inhibition of MALAT1 in isolated islets of Langerhans 72 hours after administration of a single dose of GLP-1 conjugated antisense oligonucleotides with various linkers to C57BL / 6Crl mice. To determine whether the chemistry of GLP-1 peptide conjugation to ASO affects ASO delivery into the pancreas, female C57BL / 6Crl mice (n=6) received single subcutaneous injections of ION 1086699 (GLP-1 conjugated MALAT-1 ASO conjugated via maleimide linker), ION 1123118 (GLP-1 conjugated MALAT-1 ASO conjugated via maleimide acid linker), or ION 1134165 (GLP-1 conjugated MALAT-1 ASO conjugated via disulfide linker) at concentrations of 0.03, 0.01, 0.001, or 0.0003 μmol / kg. A group of mice (n=6) was subcutaneously injected with 0.01 μmol / kg of ISIS 816385 (GLP-1 conjugated MALAT-1 ASO conjugated via a disulfide linker, as described in Example 1). Another group of mice (n=6) was subcutaneously injected with PBS, which served as a control group for comparison with the other groups. Islets were isolated 72 hours after subcutaneous administration to evaluate the delivery and potency of the compound. Percentage inhibition of MALAT1 mRNA levels was quantified as described herein (Example 9) and averaged for each treatment group against PBS-treated animals (control). 0% inhibition reflects no inhibition of MALAT1 mRNA. ND means that no mice were administered the indicated dose.
[0511] [Table 6]
[0512] The results indicate that GLP-1 conjugated MALAT-1 ASO conjugated via a maleimide acid linker showed a higher dose-response inhibition of MALAT-1 mRNA in pancreatic islet cells compared to GLP-1 conjugated MALAT-1 ASO conjugated via a maleimide or disulfide linker.
[0513] Example 31: Effect of linker on food intake in C57BL / 6Crl mice treated with GLP-1 conjugate antisense oligonucleotides Eight mice were administered a single subcutaneous injection of ION 816385 (GLP-1 conjugated MALAT-1 ASO conjugated via a disulfide linker) or ION 1123118 (GLP-1 conjugated MALAT-1 ASO conjugated via a maleimide acid linker) at concentrations of 0.01, 0.03, or 0.1 μmol / kg, as shown in the table below, and their food intake was monitored for 24 hours. Food intake was monitored as a control for eight mice administered subcutaneous injection of PBS. The maleimide acid linker increased the therapeutic window associated with GLP1-induced food intake decline compared to the disulfide linker.
