[0001] Sequence Listing This application has been filed with a Sequence Listing in electronic format. The Sequence Listing is provided under the filename BIOL0393WOSEQ_ST25.txt, created on November 3, 2021, and is 32 KB in size. The information in the electronic format of this Sequence Listing is incorporated herein by reference in its entirety.
[0002] Compounds, methods, and pharmaceutical compositions are provided for reducing the amount or activity of angiotensinogen RNA in a cell or a subject, and in certain examples, for reducing the amount of angiotensinogen (AGT) in a cell or a subject. Such compounds and pharmaceutical compositions are useful for ameliorating at least one symptom or characteristic of a RAAS pathway-related disease or disorder. Such diseases and disorders include hypertension, hypertensive emergency (i.e., malignant hypertension), resistant hypertension, kidney disease (e.g., chronic kidney disease, polycystic kidney disease), pre-eclampsia, Marfan syndrome, stroke, heart disease (e.g., myocardial infarction, heart failure, congestive heart failure, valvular heart disease), vascular aneurysm, abdominal aneurysm, peripheral arterial disease, organ damage, pulmonary arterial hypertension, obesity, metabolic syndrome, NASH, NAFLD, and other RAAS-related diseases, disorders, and / or conditions, or symptoms thereof. [Background technology]
[0003] Angiotensinogen (AGT), also known as SERPINA8 or ANHU, is a member of the serpin family and a component of the renin-angiotensin-aldosterone system (RAAS). It is primarily produced in the liver and released into the circulation, where renin converts it to angiotensin I. Angiotensin I is then converted to angiotensin II by angiotensin-converting enzyme (ACE). Angiotensin II is a peptide hormone that can cause vasoconstriction and increase blood pressure. Angiotensin II also stimulates the secretion of the hormone aldosterone from the adrenal cortex. Aldosterone increases sodium and water reabsorption in the kidney, increasing fluid volume in the body and increasing blood pressure. Stimulation or overactivity of the RAAS pathway can lead to high blood pressure. Chronic high blood pressure is known as hypertension. High blood pressure in hypertensive subjects requires the heart to work harder to circulate blood through the blood vessels.
[0004] Hypertension remains a leading cause of death and disability worldwide due to cardiovascular disease and stroke. Despite extensive research and the availability of multiple effective treatments, hypertension remains a significant public health challenge in the United States (Sigmund et al., Hypertension 2020, 75:902-917). Currently approved treatments for hypertension have limitations, and a significant proportion of all hypertensive patients do not achieve adequate blood pressure control. For example, drugs such as ACE inhibitors and angiotensin receptor blockers (ARBs), which target parts of the renin-angiotensin system (RAS) pathway, have limited ability to inhibit the RAAS pathway (Nobakht et al., Nat Rev Nephrol, 2011, 7:356-359). Furthermore, certain antihypertensive medications, such as ACE inhibitors, are contraindicated in hypertensive patients with renal disease because they may impair renal function.
[0005] Therefore, there is a need to find alternative therapies to inhibit the RAAS pathway and treat hypertension. Accordingly, it is an object of the present invention to provide compounds, methods, and pharmaceutical compositions for treating such diseases. Summary of the Invention

[0264] 1. Certain sugar moieties In certain embodiments, the modified sugar moiety is a non-bicyclic modified sugar moiety. In certain embodiments, the modified sugar moiety is a bicyclic or tricyclic sugar moiety. In certain embodiments, the modified sugar moiety is a sugar surrogate. Such sugar surrogates may contain one or more substitutions corresponding to other types of modified sugar moieties.
[0265] In certain embodiments, the modified sugar moiety is a non-bicyclic modified sugar moiety comprising a furanosyl ring bearing one or more substituents, none of which bridges two atoms of the furanosyl ring to form a bicyclic structure. Such non-bridging substituents may be located at any position on the furanosyl, including, but not limited to, substituents at the 2', 4', and / or 5' positions. In certain embodiments, one or more of the non-bridging substituents on the non-bicyclic modified sugar moiety is branched. Examples of suitable 2'-substituents on non-bicyclic modified sugar moieties include, but are not limited to, 2'-F, 2'-OCH3 ("OMe" or "O-methyl"), and 2'-O(CH2)2OCH3 ("MOE" or "O-methoxyethyl"). In certain embodiments, the 2'-substituent is halo, allyl, amino, azido, SH, CN, OCN, CF3, OCF3, O-C1-C 10 Alkoxy, O-C1-C 10 Substituted alkoxy, O-C-C 10 Alkyl, O-C1-C 10 Substituted alkyl, S-alkyl, N(R m )-alkyl, O-alkenyl, S-alkenyl, N(R m )-alkenyl, O-alkynyl, S-alkynyl, N(R m)-alkynyl, O-alkylenyl-O-alkyl, alkynyl, alkaryl, aralkyl, O-alkaryl, O-aralkyl, O(CH2)2SCH3, O(CH2)2ON(R m )(R n ), or OCH2C(=O)-N(R m )(R n ) and each R m and R n are independently H, an amino protecting group, or a substituted or unsubstituted C-C 10 The 2'-substituents are alkyl, and are described in Cook et al., US Pat. No. 6,531,584, Cook et al., US Pat. No. 5,859,221, and Cook et al., US Pat. No. 6,005,087. Certain embodiments of these 2'-substituents can be further substituted with one or more substituents independently selected from hydroxyl, amino, alkoxy, carboxy, benzyl, phenyl, nitro(NO), thiol, thioalkoxy, thioalkyl, halogen, alkyl, aryl, alkenyl, and alkynyl. Examples of suitable 4'-substituents for non-bicyclic modified sugar moieties include, but are not limited to, alkoxy (e.g., methoxy), alkyl, and those described in Manoharan et al., WO 2015 / 106128. Examples of suitable 5'-substituents for non-bicyclic modified sugar moieties include 5'-methyl (R or S), 5'-vinyl, and 5'-methoxy. In certain embodiments, non-bicyclic modified sugar moieties include two or more non-bridging sugar substituents, e.g., 2'-F-5'-methyl sugar moieties, as well as modified sugar moieties and modified nucleosides described in Migawa et al., WO2008 / 101157 and Rajeev et al., US2013 / 0203836.

[0268] In certain embodiments, 2'-substituted non-bicyclic modified nucleosides comprise a sugar moiety comprising a non-bridging 2'-substituent selected from F, OCH3, and OCH2CH2OCH3.
[0269] In certain embodiments, modified furanosyl sugar moieties and nucleosides incorporating such modified furanosyl sugar moieties are further defined by their isomeric configuration. For example, the 2'-deoxyfuranosyl sugar moiety may have seven isomeric configurations other than the naturally occurring β-D-deoxyribosyl configuration. Such modified sugar moieties are described, for example, in WO2019 / 157531, which is incorporated herein by reference. Compared to the 2'-deoxyfuranosyl sugar moiety, the 2'-modified sugar moiety has an additional stereocenter at the 2'-position; therefore, such sugar moieties have a total of 16 possible isomeric configurations. The 2'-modified sugar moieties described herein are in the β-D-ribosyl isomeric configuration unless otherwise specified.
[0270] Certain modified sugar moieties include a substituent bridging two atoms of the furanosyl ring to form a second ring, resulting in a bicyclic sugar moiety.

In this specification, the general description of bicyclic nucleosides includes both isomeric configurations. When the position of a specific bicyclic nucleoside (e.g., LNA or cEt) is identified in exemplary embodiments herein, they are in the β-D configuration unless otherwise specified.
[0276] In certain embodiments, the modified sugar moiety comprises one or more non-bridging sugar substituents and one or more bridging sugar substituents (eg, 5'-substituted and 4'-2'-bridging sugars).

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, the modified sugar moiety also includes bridging and / or non-bridging substituents as described herein. For example, certain sugar surrogates include a 4'-sulfur atom and a substitution at the 2' position (see, e.g., Bhat et al., US 7,875,733 and Bhat et al., US 7,939,677) and / or a substitution at the 5' position.

[0293] 3. Certain modified internucleoside linkages In certain embodiments, the nucleosides of modified oligonucleotides may be linked together using any internucleoside linkage. Two major classes of internucleoside linking groups are defined by the presence or absence of a phosphorus atom. Representative phosphorus-containing internucleoside linkages include, but are not limited to, phosphodiesters, including phosphodiester linkages ("P(O2)=O") (also referred to as unmodified or native linkages), phosphotriesters, methylphosphonates, phosphoramidates, phosphorothioates ("P(O2)=S"), and phosphorodithioates ("HS-P=S"). Representative non-phosphorus-containing internucleoside linkage groups include, but are not limited to, methylenemethylimino (-CH-N(CH)-O-CH-), thiodiester, thionocarbamate (-OC(=O)(NH)-S-), siloxane (-O-SiH-O-), and N,N'-dimethylhydrazine (-CH-N(CH)-N(CH)-). Modified internucleoside linkages can be used to alter, typically increase, the nuclease resistance of oligonucleotides compared to natural phosphodiester internucleoside linkages. In certain embodiments, internucleoside linkages having a chiral atom can be prepared as a racemic mixture or as separate enantiomers. Methods for preparing phosphorus-containing and non-phosphorus-containing internucleoside linkages are well known to those skilled in the art.
[0294] Representative internucleoside linkages having a chiral center include, but are not limited to, alkylphosphonates and phosphorothioates. Modified oligonucleotides containing internucleoside linkages having a chiral center can be prepared as a population of modified oligonucleotides containing stereorandom internucleoside linkages or as a population of modified oligonucleotides containing phosphorothioate internucleoside linkages in a specific stereochemical configuration. In certain embodiments, the population of modified oligonucleotides contains phosphorothioate internucleoside linkages, and all phosphorothioate internucleoside linkages are stereorandom. Such modified oligonucleotides can be produced using synthetic methods that result in random selection of the stereochemical configuration of each phosphorothioate internucleoside linkage. Nevertheless, as will be appreciated by those skilled in the art, each individual phosphorothioate in each individual oligonucleotide molecule has a defined stereochemical configuration. In certain embodiments, the population of modified oligonucleotides is enriched for modified oligonucleotides containing one or more specific phosphorothioate internucleoside linkages in a specific, independently selected stereochemical configuration. In certain embodiments, a particular arrangement of phosphorothioate internucleoside linkages is present in at least 65% of the molecules in the population. In certain embodiments, a particular arrangement of phosphorothioate internucleoside linkages is present in at least 70% of the molecules in the population. In certain embodiments, a particular arrangement of phosphorothioate internucleoside linkages is present in at least 80% of the molecules in the population. In certain embodiments, a particular arrangement of phosphorothioate internucleoside linkages is present in at least 90% of the molecules in the population. In certain embodiments, a particular arrangement of phosphorothioate internucleoside linkages is present in at least 99% of the molecules in the population.Such chirally enriched populations of modified oligonucleotides can be produced using synthetic methods known in the art, such as those described in Oka et al., JACS 125, 8307 (2003), Wan et al., Nuc. Acid. Res. 42, 13456 (2014), and WO 2017 / 015555. In certain embodiments, the population of modified oligonucleotides is enriched for modified oligonucleotides having at least one of the indicated phosphorothioates in the (Sp) configuration. In certain embodiments, the population of modified oligonucleotides is enriched for modified oligonucleotides having at least one phosphorothioate in the (Rp) configuration. In certain embodiments, the modified oligonucleotides containing (Rp) and / or (Sp) phosphorothioates each comprise one or more of the following formulae, where "B" represents a nucleobase:
[0295] [ka]
[0296] Unless otherwise specified, the chiral internucleoside linkages of the modified oligonucleotides described herein can be stereorandom or can be in a specific stereochemical configuration.
[0297] Neutral internucleoside linkages include, but are not limited to, phosphotriester, methylphosphonate, MMI (3'-CH2-N(CH3)-O-5'), amide-3 (3'-CH2-C(=O)-N(H)-5'), amide-4 (3'-CH2-N(H)-C(=O)-5'), formacetal (3'-O-CH2-O-5'), methoxypropyl (MOP), and thioformacetal (3'-S-CH2-O-5'). Additional neutral internucleoside linkages include nonionic linkages, including siloxanes (dialkylsiloxanes), carboxylate esters, carboxamides, sulfides, sulfonate esters, and amides (see, e.g., Carbohydrate Modifications in Antisense Research, YS Sanghvi and PD Cook, Eds., ACS Symposium Series 580, Chapters 3 and 4, 40-65). Additional neutral internucleoside linkages include nonionic linkages containing mixed N, O, S, and CH constituent moieties.

In certain embodiments, modified oligonucleotides comprise one or more modified nucleosides containing modified nucleobases. In certain embodiments, modified oligonucleotides comprise one or more modified internucleoside linkages. In such embodiments, the modified, unmodified, and differently modified sugar moieties, nucleobases, and / or internucleoside linkages of modified oligonucleotides define a pattern or motif. In certain embodiments, the sugar moiety, nucleobase, and internucleoside linkage patterns are each independent of one another. Thus, modified oligonucleotides can be described by their sugar motif, nucleobase motif, and / or internucleoside linkage motif (as used herein, nucleobase motif describes modifications to nucleobases that are independent of the sequence of the nucleobases).
[0299] 1.

[0300] In certain embodiments, the modified oligonucleotides have a gapmer motif defined by two external regions or "wings" and a central or internal region or "gap." The three regions of the gapmer motif (the 5'-wing, the gap, and the 3'-wing) form a contiguous sequence of nucleosides, with at least a portion of the sugar moieties of each nucleoside in the wing being different 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'-most nucleoside of the 5'-wing and the 5'-most nucleoside of the 3'-wing) are different from the sugar moieties of the adjacent gap nucleosides, thus defining the boundary between the wing and the gap (i.e., the wing / gap junction). In certain embodiments, the sugar moieties within the gap are the same as each other. In certain embodiments, the gap contains one or more nucleosides having sugar moieties that are different 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 gapmers). In certain embodiments, the sugar motif of the 5'-wing is different from the sugar motif of the 3'-wing (asymmetric sugar gapmers).

In certain embodiments, at least one nucleoside of the gapmer gap comprises a modified sugar moiety. In certain embodiments, at least one nucleoside of the gapmer gap comprises a 2'-OMe sugar moiety.
[0303] In certain embodiments, the gapmer is a deoxygapmer. In certain embodiments, nucleosides on the gap side of each wing / gap junction comprise a 2'-deoxyribosyl sugar moiety, and nucleosides on the wing side of each wing / gap junction comprise a modified sugar moiety. In certain embodiments, at least six nucleosides of the gap of the gapmer comprise a 2'-β-D-deoxyribosyl sugar moiety. In certain embodiments, each nucleoside of the gap comprises a 2'-deoxyribosyl sugar moiety. In certain embodiments, each nucleoside of each wing of the gapmer comprises a modified sugar moiety. In certain embodiments, one nucleoside of the gap comprises a modified sugar moiety, and each remaining nucleoside of the gap comprises a 2'-deoxyribosyl sugar moiety.
[0304] In certain embodiments, a modified oligonucleotide comprises or consists of a portion having a fully modified sugar motif. In such embodiments, each nucleoside of the fully modified portion of the modified oligonucleotide comprises a modified sugar moiety. In certain embodiments, each nucleoside throughout the modified oligonucleotide comprises a modified sugar moiety. In certain embodiments, a modified oligonucleotide comprises or consists of a portion having a fully modified sugar motif, and each nucleoside within the fully modified portion comprises the same modified sugar moiety, referred to herein as a uniformly modified sugar motif. In certain embodiments, a fully modified oligonucleotide is a uniformly modified oligonucleotide. In certain embodiments, each nucleoside of a uniformly modified oligonucleotide comprises the same 2'-modification.
[0305] As used herein, the lengths (number of nucleosides) of the three regions of a gapmer may be provided using the notation [number of nucleosides in the 5'-wing] - [number of nucleosides in the gap] - [number of nucleosides in the 3'-wing]. Thus, a 5-10-5 gapmer consists of five linked nucleosides in each wing and ten linked nucleosides in the gap. When such nomenclature is followed by a specific modification, the modification is in each sugar moiety of each wing, and the gap nucleosides are composed of a 2'-β-D-deoxyribosyl sugar moiety. Thus, a 5-10-5 MOE gapmer consists of five linked 2'-MOE nucleosides in the 5'-wing, ten linked 2'-β-D-deoxynucleosides in the gap, and five linked 2'-MOE nucleosides in the 3'-wing. A 3-10-3 cEt gapmer consists of three linked cEt nucleosides in the 5'-wing, ten linked 2'-β-D-deoxynucleosides in the gap, and three linked cEt nucleosides in the 3'-wing. A 5-8-5 gapmer consists of five linked nucleosides with modified sugar moieties in the 5'-wing, eight linked 2'-deoxynucleosides in the gap, and five linked nucleosides with modified sugar moieties in the 3'-wing. A mixed-wing gapmer has at least two different modified sugars in the 5' and / or 3' wings. A 5-8-5 or 5-8-4 mixed-wing gapmer has at least two different modified sugar moieties in the 5' and / or 3' wings.

In certain such embodiments, the sugar moiety of the nucleoside is a 2'-deoxyribosyl sugar moiety. In certain embodiments, the modified nucleobase is selected from 2-thiopyrimidine and 5-propynepyrimidine.
[0311] 3. Certain internucleoside linkage motifs In certain embodiments, an oligonucleotide comprises modified and / or unmodified internucleoside linkages arranged in a defined pattern or motif along the oligonucleotide or portion thereof. In certain embodiments, each internucleoside linkage group is a phosphodiester internucleoside linkage (P(O2)=O). In certain embodiments, each internucleoside linkage group of a modified oligonucleotide is a phosphorothioate internucleoside linkage (P(O2)=S). In certain embodiments, each internucleoside linkage of a modified oligonucleotide is independently selected from a phosphorothioate internucleoside linkage and a phosphodiester internucleoside linkage.

[0314] C. A certain total length The length of the oligonucleotide can be increased or decreased without eliminating activity. For example, Woolf et al. (Proc. Natl. Acad. Sci. USA 89:7305-7309, 1992) tested a series of oligonucleotides ranging from 13 to 25 nucleobases in length for their ability to induce cleavage of target nucleic acids in an oocyte injection model. 25 nucleobase-long oligonucleotides with 8 or 11 mismatched bases near the end of the oligonucleotide were able to induce specific cleavage of target nucleic acids, albeit to a lesser extent than oligonucleotides without mismatches. Similarly, target-specific cleavage was achieved using 13 nucleobase oligonucleotides, including those with one or three mismatches.
[0315] In certain embodiments, oligonucleotides (including modified oligonucleotides) can have any of a variety of length ranges. In certain embodiments, an oligonucleotide consists of X to Y linked nucleosides, where X represents the minimum number of nucleosides in the range and Y represents the maximum number of nucleosides in the range. In certain such embodiments, X and Y are each independently selected from 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, and 50, provided that X is less than or equal to Y. For example, in certain embodiments, the oligonucleotides may be 12-13, 12-14, 12-15, 12-16, 12-17, 12-18, 12-19, 12-20, 12-21, 12-22, 12-23, 12-24, 12-25, 12-26, 12-27, 12-28, 12-29, 12-30, 13-14, 13-15, 13-16, 13-17, 13-18, 13-19, 13-20, 13-21, 13-22, 13-23, 13-24, 13-25, 13-26, 13-27, 13-28, 13-29, 13-30, 14-15, 14-16, 14-17, 14-18, 14-19, 14-20, 14-21, 14-22, 14-23, 14-24, 14-25, 14-26, 14-27, 14-28, 14-29, 14-30 0, 15-16, 15-17, 15-18, 15-19, 15-20, 15-21, 15-22, 15-23, 15-24, 15-25, 15-26, 15-27, 15-28, 15-29, 15-30, 16-17, 16-18, 16-19, 16-20, 16-21, 16-22, 16-23, 16-24, 16-25, 16-26, 16-27, 16-28, 16 ~29, 16~30, 17~18, 17~19, 17~20, 17~21, 17~22, 17~23, 17~24, 17~25, 17~26, 17~27, 17~28, 17~29, 17~30, 18~19, 18~20, 18~21, 18~22, 18~23, 18~24, 18~25, 18~26, 18~27, 18~28, 18~29, 18~30, 19~20,19-21, 19-22, 19-23, 19-24, 19-25, 19-26, 19-29, 19-28, 19-29, 19-30, 20-21, 20-22, 20-23, 20-24, 20-25, 20-26, 20-27, 20-28, 20-29, 20-30, 21-22, 21-23, 21-24, 21-25, 21-26, 21-27, 21-28, 21-29, 21-30, 22-23, 22-24, 22-25, 22-26, 22-27, 2 Consisting of 2 to 28, 22 to 29, 22 to 30, 23 to 24, 23 to 25, 23 to 26, 23 to 27, 23 to 28, 23 to 29, 23 to 30, 24 to 25, 24 to 26, 24 to 27, 24 to 28, 24 to 29, 24 to 30, 25 to 26, 25 to 27, 25 to 28, 25 to 29, 25 to 30, 26 to 27, 26 to 28, 26 to 29, 26 to 30, 27 to 28, 27 to 29, 27 to 30, 28 to 29, 28 to 30, or 29 to 30 linked nucleosides.
[0316] D. Certain Modified Oligonucleotides In certain embodiments, the above-described modifications (sugar, nucleobase, internucleoside linkage) are incorporated into modified oligonucleotides. In certain embodiments, modified oligonucleotides are characterized by their modification motif and overall length. In certain embodiments, such parameters are each independent of one another. Thus, unless otherwise indicated, each internucleoside linkage of an oligonucleotide having a gapmer sugar motif can be modified or unmodified, and the sugar modification may or may not follow the gapmer modification pattern. For example, the internucleoside linkages within the wing regions of a sugar gapmer can be the same or different from one another and the same or different from the internucleoside linkages in the gap region of the sugar motif. Similarly, such sugar gapmer oligonucleotides can contain one or more modified nucleobases regardless of the gapmer pattern of sugar modification. Unless otherwise indicated, any modification is independent of the nucleobase sequence.
[0317] E. Certain populations of modified oligonucleotides A population of modified oligonucleotides, in which all modified oligonucleotides in the population have the same molecular formula, can be a stereorandom population or a chirally enriched population. All chiral centers of all modified oligonucleotides in the stereorandom population are stereorandom. In a chirally enriched population, at least one specific chiral center is not stereorandom among the modified oligonucleotides in the population.

[0324] 2. Conjugate Linker The conjugate moiety is linked to the oligonucleotide via a conjugate linker.In certain oligomeric compounds, the conjugate linker is a single chemical bond (i.e., the conjugate moiety is directly linked to the oligonucleotide via a single bond).In certain oligomeric compounds, the conjugate moiety is linked to the oligonucleotide via a more complex conjugate linker, which comprises one or more conjugate linker moieties, which are the subunits that make up the conjugate linker.In certain embodiments, the conjugate linker comprises a chain structure such as a hydrocarbyl chain, or an oligomer of repeating units such as ethylene glycol, nucleoside, or amino acid units.
[0325] In certain embodiments, the conjugate linker comprises one or more groups selected from alkyl, amino, oxo, amido, disulfide, polyethylene glycol, ether, thioether, and hydroxylamino. In certain such embodiments, the conjugate linker comprises a group selected from alkyl, amino, oxo, amido, and ether groups.

In certain embodiments, the conjugate linker comprises a group 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 linking group.
[0326] In certain embodiments, the conjugate linker, including the conjugate linkers described above, is a bifunctional linking moiety, e.g., one known in the art to be useful for attaching a conjugate group to a parent compound, such as an oligonucleotide, provided herein. Generally, a bifunctional linking moiety contains at least two functional groups. One of the functional groups is selected to bind to a specific site on the parent compound, and the other is selected to bind to a conjugate group. Examples of functional groups used in bifunctional linking moieties include, but are not limited to, electrophilic groups for reacting with nucleophilic groups and nucleophilic groups for reacting with electrophilic groups. In certain embodiments, the bifunctional linking moiety contains one or more groups selected from amino, hydroxyl, carboxylic acid, thiol, alkyl, alkenyl, and alkynyl.
[0327] Examples of conjugate linkers include, but are not limited to, pyrrolidine, 8-amino-3,6-dioxaoctanoic acid (ADO), succinimidyl 4-(N-maleimidomethyl)cyclohexane-1-carboxylate (SMCC), and 6-aminohexanoic acid (AHEX or AHA). Other conjugate linkers include substituted or unsubstituted C1-C 10 Alkyl, substituted or unsubstituted C2-C 10 Alkenyl, or substituted or unsubstituted C-C 10 Alkynyl is included, and a non-limiting list of preferred substituents includes, but is not limited to, hydroxyl, amino, alkoxy, carboxy, benzyl, phenyl, nitro, thiol, thioalkoxy, halogen, alkyl, aryl, alkenyl, and alkynyl.
[0328] In certain embodiments, a conjugate linker comprises 1 to 10 linker nucleosides. In certain embodiments, a conjugate linker comprises 2 to 5 linker nucleosides. In certain embodiments, a conjugate linker comprises exactly 3 linker nucleosides. In certain embodiments, a conjugate linker comprises a TCA motif. In certain embodiments, such linker nucleosides are modified nucleosides. In certain embodiments, such linker nucleosides comprise a modified sugar moiety. In certain embodiments, a linker nucleoside is unmodified. In certain embodiments, a linker nucleoside comprises an optionally protected heterocyclic base selected from a purine, a substituted purine, a pyrimidine, or a substituted pyrimidine. 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. It is generally desirable for the linker nucleosides to be cleaved from the oligomeric compound after reaching the target tissue. Therefore, the linker nucleosides are typically linked to each other and to the remainder of the oligomeric compound via a cleavable bond. In certain embodiments, such a cleavable bond is a phosphodiester bond.
[0329] As used herein, linker nucleosides are not considered part of an oligonucleotide. Thus, in embodiments where an oligomeric compound comprises an oligonucleotide consisting of a specific number or range of linked nucleosides and / or a specific percentage of complementarity with a reference nucleic acid, and the oligomeric compound also comprises a conjugate group comprising a conjugate linker containing linker nucleosides, these linker nucleosides are not counted in the length of the oligonucleotide and are not used in determining the percent complementarity of the oligonucleotide to the reference nucleic acid. For example, an oligomeric compound may comprise (1) a modified oligonucleotide consisting of 8 to 30 nucleosides and (2) a conjugate group comprising 1 to 10 linker nucleosides contiguous with the nucleosides of the modified oligonucleotide. The total number of contiguous linked nucleosides in such an oligomeric compound exceeds 30. Alternatively, an oligomeric compound may comprise a modified oligonucleotide consisting of 8 to 30 nucleosides and no conjugate group. The total number of consecutive linked nucleosides in such oligomeric compounds is 30 or less. Unless otherwise specified, the conjugate linker contains 10 or less linker nucleosides. In certain embodiments, the conjugate linker contains 5 or less linker nucleosides. In certain embodiments, the conjugate linker contains 3 or less linker nucleosides. In certain embodiments, the conjugate linker contains 2 or less linker nucleosides. In certain embodiments, the conjugate linker contains 1 or less linker nucleoside.
[0330] In certain embodiments, it is desirable that the conjugate group be cleaved from the oligonucleotide.For example, in certain situations, oligomeric compounds containing certain conjugate moieties are more likely to be taken up by certain cell types, and after the oligomeric compound is taken up, it is desirable that the conjugate group be cleaved to release the unconjugated or parent oligonucleotide.Therefore, certain conjugate linkers can contain one or more cleavable moieties.In certain embodiments, the cleavable moiety is a cleavable bond.In certain embodiments, the cleavable moiety is an atomic group that includes at least one cleavable bond.In certain embodiments, the cleavable moiety includes an atomic group that has one, two, three, four, or more than four cleavable bonds.In certain embodiments, the cleavable moiety is selectively cleaved inside a cell or intracellular compartment, such as a lysosome.In certain embodiments, the cleavable moiety is selectively cleaved by an endogenous enzyme, such as a nuclease.
[0331] In certain embodiments, the cleavable bond is selected from among amide, ester, ether, one or both esters of phosphodiester, phosphate ester, carbamate, or disulfide. In certain embodiments, the cleavable bond is one or both esters of phosphodiester. In certain embodiments, the cleavable moiety comprises a phosphate or phosphodiester. In certain embodiments, the cleavable moiety is a phosphate or phosphodiester bond between the oligonucleotide and the conjugate moiety or conjugate group.
[0332] 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 linked to each other and / or to the remainder of the oligomeric compound by a cleavable bond. In certain embodiments, such cleavable bonds are unmodified phosphodiester bonds. In certain embodiments, the cleavable moiety is a 2'-deoxyribonucleoside linked to either the 3'- or 5'-terminal nucleoside of the oligonucleotide by a phosphodiester internucleoside bond and covalently linked to the remainder of the conjugate linker or conjugate moiety by a phosphate or phosphorothioate internucleoside bond. In certain such embodiments, the cleavable moiety is 2'-deoxyadenosine.
[0333] 3.Cell targeting part In certain embodiments, the conjugate group comprises a cell targeting moiety. In certain embodiments, the conjugate group has the general formula:
[0334] [ka]
[0335] In the formula, n is 1 to about 3, m is 0 when n is 1, m is 1 when n is 2 or more, j is 1 or 0, and k is 1 or 0.
[0336] In certain embodiments, n is 1, j is 1, and k is 0. In certain embodiments, n is 1, j is 0, and k is 1. In certain embodiments, n is 1, j is 1, and k is 1. In certain embodiments, n is 1, j is 1, and k is 1. In certain embodiments, n is 2, j is 1, and k is 0. In certain embodiments, n is 2, j is 0, and k is 1.

In certain embodiments, the cell-targeting moiety comprises two tethered ligands covalently bonded to the branching group. In certain embodiments, the cell-targeting moiety comprises three tethered ligands covalently bonded to the branching group.

In certain such embodiments, the oligomeric compound comprises a stabilized 5'-phosphate. Stabilized 5'-phosphates include, but are not limited to, 5'-phosphonates, including, but not limited to, 5'-vinylphosphonates. In certain embodiments, the terminal group comprises one or more abasic nucleosides and / or reverse nucleosides. In certain embodiments, the terminal group comprises one or more 2'-linked nucleosides. In certain such embodiments, the 2'-linked nucleosides are abasic nucleosides.
[0339] III. Oligomeric Duplexes In certain embodiments, the oligomeric compounds described herein comprise an oligonucleotide having a nucleobase sequence complementary to that of a target nucleic acid. In certain embodiments, the oligomeric compound pairs with a second oligomeric compound to form an oligomeric duplex. Such an oligomeric duplex comprises a first oligomeric compound having a portion complementary to the target nucleic acid and a second oligomeric compound having a portion complementary to the first oligomeric compound. In certain embodiments, the first oligomeric compound of the oligomeric duplex comprises or consists of (1) a modified or unmodified oligonucleotide and optionally a conjugate group, and (2) a second modified or unmodified oligonucleotide and optionally a conjugate group. One or both oligomeric compounds of the oligomeric duplex may comprise a conjugate group. The oligonucleotides of each oligomeric compound of the oligomeric duplex may comprise non-complementary overhanging nucleosides.
[0340] IV. Antisense Activity In certain embodiments, oligomeric compounds and oligomeric duplexes can hybridize to a target nucleic acid to confer at least one antisense activity. Such oligomeric compounds and oligomeric duplexes are antisense compounds. In certain embodiments, antisense compounds have antisense activity if they reduce the amount or activity of the target nucleic acid by 25% or more in a standard cell assay. In certain embodiments, antisense compounds selectively act on one or more target nucleic acids. Such antisense compounds comprise a nucleobase sequence that hybridizes to one or more target nucleic acids to confer one or more desired antisense activities, but does not hybridize to one or more non-target nucleic acids or does not hybridize to one or more non-target nucleic acids in a manner that results in significant undesired antisense activity.
[0341] In certain antisense activities, hybridization of an antisense compound to a target nucleic acid results in the recruitment of a protein that cleaves the target nucleic acid. For example, certain antisense compounds 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 duplex. The DNA in such an RNA:DNA duplex need not be unmodified DNA. In certain embodiments, antisense compounds are described herein as being "DNA-like" enough to induce RNase H activity. In certain embodiments, one or more non-DNA-like nucleosides within the gap of a gapmer are tolerated.
[0342] In certain antisense activity, antisense compound or antisense compound part is incorporated into RNA-induced silencing complex (RISC), and finally leads to the cleavage of target nucleic acid.For example, certain antisense compound leads to the cleavage of target nucleic acid by Argonaute.The antisense compound that is incorporated into RISC is RNAi compound.RNAi compound can be double-stranded (siRNA) or single-stranded (ssRNA).
[0343] In certain embodiments, the hybridization of an antisense compound to a target nucleic acid does not result in the recruitment of a protein that cleaves the target nucleic acid.In certain embodiments, the hybridization of an antisense compound to a target nucleic acid results in a change in the splicing of the target nucleic acid.In certain embodiments, the hybridization of an antisense compound to a target nucleic acid results in the inhibition of the binding interaction between the target nucleic acid and a protein or other nucleic acid.In certain embodiments, the hybridization of an antisense compound to a target nucleic acid results in a change in the translation of the target nucleic acid.
[0344] Antisense activity can be observed directly or indirectly, hi certain embodiments, observing or detecting antisense activity involves observing or detecting a change in the amount of a target nucleic acid or a protein encoded by such a target nucleic acid, a change in the ratio of splice variants of the nucleic acid or protein, and / or a change in the phenotype of a cell or subject.
[0345] V. Certain Target Nucleic Acids In certain embodiments, the oligomeric compound comprises or consists of an oligonucleotide comprising a portion complementary to the target nucleic acid. In certain embodiments, the target nucleic acid is an endogenous RNA molecule. In certain embodiments, the target nucleic acid encodes a protein. In certain such embodiments, the target nucleic acid is selected from mature mRNA and pre-mRNA, which comprise introns, exons, and untranslated regions. In certain embodiments, the target nucleic acid is a mature mRNA. In certain embodiments, the target nucleic acid is a pre-mRNA. In certain 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.
[0346] A. Complementarity / Mismatch with Target Nucleic Acid It is possible to introduce mismatched bases without losing activity. For example, Gautschi et al. (J. Natl. Cancer Inst. 93:463-471, March 2001) demonstrated the ability of an oligonucleotide with 100% complementarity to bcl-2 mRNA and three mismatches to bcl-xL mRNA to reduce the expression of both bcl-2 and bcl-xL in vitro and in vivo. Furthermore, this oligonucleotide also exhibited potent antitumor activity in vivo. Maher and Dolnick (Nuc. Acid. Res. 16:3341-3358, 1988) tested a series of tandem 14 nucleobase oligonucleotides, as well as 28 and 42 nucleobase oligonucleotides composed of two or three sequences of the tandem oligonucleotide, for their ability to terminate the translation of human DHFR in a rabbit reticulocyte assay. Each of the three 14 nucleobase oligonucleotides alone was able to inhibit translation, albeit to a more modest degree than the 28 or 42 nucleobase oligonucleotides.
[0347] In certain embodiments, the oligonucleotide is complementary to the target nucleic acid over the entire length of the oligonucleotide.In certain embodiments, the oligonucleotide is 99%, 95%, 90%, 85%, or 80% complementary to the target nucleic acid.In certain embodiments, the oligonucleotide is at least 80% complementary to the target nucleic acid over the entire length of the oligonucleotide, and comprises a portion that is 100% or completely complementary to the target nucleic acid.In certain embodiments, the completely complementary portion is 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, or 24 nucleobases in length.
[0348] In certain embodiments, the oligonucleotide comprises one or more mismatched nucleobases with respect to the target nucleic acid. In certain embodiments, the antisense activity against the target is reduced by such mismatches, while the activity against non-targets is reduced to a greater extent. Thus, in certain embodiments, the selectivity of the oligonucleotide is improved. In certain embodiments, the mismatch is specifically located within the oligonucleotide having a gapmer motif. In certain embodiments, the mismatch is located at position 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or 11 from the 5' end of the gap region. In certain embodiments, the mismatch is located at position 1, 2, 3, 4, 5, or 6 from the 5' end of the 5' wing region or the 3' wing region.

In certain embodiments, the conjugate linker comprises at least one phosphate group. In certain embodiments, the conjugate linker comprises at least one neutral linking group.
[0359] In certain embodiments, the conjugate linker, including the conjugate linkers described above, is a bifunctional linking moiety, e.g., one known in the art to be useful for attaching a conjugate group to a parent compound, such as an oligonucleotide, provided herein. Generally, a bifunctional linking moiety contains at least two functional groups. One of the functional groups is selected to bind to a specific site on the parent compound, and the other is selected to bind to a conjugate group. Examples of functional groups used in bifunctional linking moieties include, but are not limited to, electrophilic groups for reacting with nucleophilic groups and nucleophilic groups for reacting with electrophilic groups. In certain embodiments, the bifunctional linking moiety contains one or more groups selected from amino, hydroxyl, carboxylic acid, thiol, alkyl, alkenyl, and alkynyl.
[0360] Examples of conjugate linkers include, but are not limited to, pyrrolidine, 8-amino-3,6-dioxaoctanoic acid (ADO), succinimidyl 4-(N-maleimidomethyl)cyclohexane-1-carboxylate (SMCC), and 6-aminohexanoic acid (AHEX or AHA). Other conjugate linkers include substituted or unsubstituted C1-C 10 Alkyl, substituted or unsubstituted C2-C 10 Alkenyl, or substituted or unsubstituted C-C 10 Alkynyl is included, and a non-limiting list of preferred substituents includes, but is not limited to, hydroxyl, amino, alkoxy, carboxy, benzyl, phenyl, nitro, thiol, thioalkoxy, halogen, alkyl, aryl, alkenyl, and alkynyl.
[0361] In certain embodiments, the conjugate linker comprises 1 to 10 linker nucleosides. In certain embodiments, such linker nucleosides are modified nucleosides. In certain embodiments, such linker nucleosides comprise modified sugar moieties. In certain embodiments, the linker nucleosides are unmodified. In certain embodiments, the linker nucleosides comprise an optionally protected heterocyclic base selected from a purine, a substituted purine, a pyrimidine, or a substituted pyrimidine. 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. Typically, it is desirable for the linker nucleoside to be cleaved from the compound after reaching the target tissue. Thus, the linker nucleosides are typically linked to each other and to the remainder of the compound via cleavable bonds. In certain embodiments, such cleavable bonds are phosphodiester bonds.
[0362] As used herein, linker nucleosides are not considered part of the oligonucleotide. Thus, in embodiments where a compound includes an oligonucleotide consisting of a specific number or range of linked nucleosides and / or a specific percentage of complementarity with a reference nucleic acid, and the compound also includes a conjugate group containing a conjugate linker that includes linker nucleosides, those linker nucleosides are not counted in the length of the oligonucleotide and are not used in determining the percent complementarity of the oligonucleotide to the reference nucleic acid. For example, a compound may include (1) a modified oligonucleotide consisting of 8 to 30 nucleosides and (2) a conjugate group containing 1 to 10 linker nucleosides contiguous with a nucleoside of the modified oligonucleotide. The total number of contiguous linked nucleosides in such a compound is greater than 30. Alternatively, a compound may include a modified oligonucleotide consisting of 8 to 30 nucleosides and no conjugate group. The total number of contiguous linked nucleosides in such a compound is 30 or less. Unless otherwise specified, a conjugate linker comprises 10 or fewer linker nucleosides. In certain embodiments, a conjugate linker comprises 5 or fewer linker nucleosides. In certain embodiments, a conjugate linker comprises 3 or fewer linker nucleosides. In certain embodiments, a conjugate linker comprises 2 or fewer linker nucleosides. In certain embodiments, a conjugate linker comprises 1 or fewer linker nucleosides.
[0363] In certain embodiments, it is desirable that the conjugate group be cleaved from the oligonucleotide.For example, in certain situations, a compound containing a specific conjugate moiety is better taken up by a specific cell type, and once the compound is taken up, it is desirable that the conjugate group be cleaved to release the unconjugated oligonucleotide or parent oligonucleotide.Therefore, certain conjugate linkers can contain one or more cleavable moieties.In certain embodiments, the cleavable moiety is a cleavable bond.In certain embodiments, the cleavable moiety is an atomic group that includes at least one cleavable bond.In certain embodiments, the cleavable moiety includes an atomic group that has one, two, three, four, or more than four cleavable bonds.In certain embodiments, the cleavable moiety is selectively cleaved inside a cell or intracellular compartment, such as a lysosome.In certain embodiments, the cleavable moiety is selectively cleaved by an endogenous enzyme, such as a nuclease.
[0364] In certain embodiments, the cleavable bond is selected from among amide, ester, ether, one or both esters of phosphodiester, phosphate ester, carbamate, or disulfide. In certain embodiments, the cleavable bond is one or both esters of phosphodiester. In certain embodiments, the cleavable moiety comprises a phosphate or phosphodiester. In certain embodiments, the cleavable moiety is a phosphate bond between the oligonucleotide and the conjugate moiety or conjugate group.
[0365] 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 linked to each other and / or to the remainder of the compound by a cleavable bond. In certain embodiments, such cleavable bonds are unmodified phosphodiester bonds. In certain embodiments, the cleavable moiety is a 2'-deoxynucleoside linked to either the 3'-terminal nucleoside or the 5'-terminal nucleoside of the oligonucleotide by a phosphate internucleoside bond and covalently linked to the remainder of the conjugate linker or conjugate moiety by a phosphate or phosphorothioate bond. In certain such embodiments, the cleavable moiety is 2'-deoxyadenosine.

[0397] VII. Certain Pharmaceutical Compositions In certain embodiments, provided herein are pharmaceutical compositions comprising one or more oligomeric compounds. In certain embodiments, each of the one or more oligomeric compounds consists of a modified oligonucleotide. In certain embodiments, the pharmaceutical composition includes a pharmaceutically acceptable diluent or carrier. In certain embodiments, the pharmaceutical composition comprises or consists of a saline solution and one or more oligomeric compounds.

In certain embodiments, pharmaceutical compositions comprising oligomeric compounds comprising one or more oligonucleotides can provide (directly or indirectly) biologically active metabolites or residues thereof when administered to a subject, including a human. Thus, for example, the present disclosure also covers pharmaceutically acceptable salts of oligomeric compounds, prodrugs, pharmaceutically acceptable salts of such prodrugs, and other biological equivalents. Suitable pharmaceutically acceptable salts include, but are not limited to, sodium and potassium salts. In certain embodiments, the prodrugs contain one or more conjugate groups attached to the oligonucleotide, which are cleaved by endogenous nucleases in the body.

Certain such cosolvent systems include, for example, benzyl alcohol, a nonpolar surfactant, a water-miscible organic polymer, and an aqueous phase. In certain embodiments, such cosolvent systems are used for hydrophobic compounds. A non-limiting example of such a cosolvent system is the VPD cosolvent system, which is a solution of 3% w / v benzyl alcohol, 8% w / v of the nonpolar surfactant Polysorbate 80™, and 65% w / v polyethylene glycol 300 in absolute ethanol. The proportions of such cosolvent systems can be varied considerably without significantly altering their solubility and toxicity characteristics. Furthermore, the identity of the cosolvent components may be varied; for example, other surfactants may be substituted for Polysorbate 80™, the fraction size of the polyethylene glycol may be changed, other biocompatible polymers may replace polyethylene glycol, e.g., polyvinylpyrrolidone, and other sugars or polysaccharides may replace dextrose.

[0406] Under certain conditions, certain compounds disclosed herein function as acids. Such compounds may be depicted or described in a protonated (free acid) form or an ionized (salt) form associated with a cation, and aqueous solutions of such compounds exist in equilibrium between these forms. For example, the phosphate linkage of an oligonucleotide in aqueous solution exists in equilibrium between the free acid, anionic, and salt forms. Unless otherwise indicated, the compounds disclosed herein are intended to include all such forms. Furthermore, certain oligonucleotides have several such linkages, each of which is in equilibrium. Thus, an oligonucleotide in solution exists as a collection of forms, all in equilibrium at multiple positions. The term "oligonucleotide" is intended to encompass all such forms. Illustrated structures necessarily depict a single form. Nevertheless, unless otherwise indicated, such depictions are intended to encompass corresponding forms as well. Herein, structures depicting the free acid form of a compound followed by the term "or a salt thereof" explicitly encompass all such forms, which may be fully or partially protonated, deprotonated, or associated with a cation. In certain instances, one or more specific cations are identified.
[0407] In certain embodiments, the modified oligonucleotide or oligomeric compound is in an aqueous solution containing sodium. In certain embodiments, the modified oligonucleotide or oligomeric compound is in an aqueous solution containing potassium. In certain embodiments, the modified oligonucleotide or oligomeric compound is in PBS. In certain embodiments, the modified oligonucleotide or oligomeric compound is in water. In certain such embodiments, the pH of the solution is adjusted with NaOH and / or HCl to achieve the desired pH.
[0408] Certain doses are described herein. The dose may be in the form of a dosage unit. For clarity, the dose (or dosage unit) of a modified oligonucleotide or oligomeric compound in milligrams refers to the mass of the free acid form of the modified oligonucleotide or oligomeric compound. As described above, in aqueous solution, the free acid is in equilibrium with the anionic and salt forms. However, for the purpose of calculating the dose, the modified oligonucleotide or oligomeric compound is assumed to exist as a solvent-free, sodium acetate-free, anhydrous, free acid. For example, when a modified oligonucleotide or oligomeric compound is in a solution containing sodium (e.g., saline), the modified oligonucleotide or oligomeric compound may be partially or completely deprotonated and associated with Na+ ions. However, the mass of the protons is still counted in the weight of the dose, and the mass of the Na+ ions is not counted in the weight of the dose. If the oligomeric compound contains a conjugate group, the mass of the conjugate group is included in the calculation of the dose of such an oligomeric compound. If the conjugate group also bears an acid, the conjugate group is also assumed to be fully protonated for the purposes of calculating dosage.

[0454] Non-Limiting Disclosure and Incorporation by Reference Each of the literature and patent publications cited herein is incorporated by reference in its entirety.
[0455] While certain compounds, compositions, and methods described herein are specifically described according to certain embodiments, the following examples are merely illustrative of the compounds described herein and are not intended to be limiting thereof. Each of the references, GenBank accession numbers, etc. listed in this application is incorporated herein by reference in its entirety.
[0456] Although the sequence listing accompanying this application identifies each sequence as either "RNA" or "DNA," as appropriate, in practice, these sequences can be modified with any combination of chemical modifications. Those of skill in the art will readily understand that the designation as "RNA" or "DNA" to describe modified oligonucleotides is, in certain instances, arbitrary. For example, an oligonucleotide containing a nucleoside containing a 2'-OH sugar moiety and a thymine base can be described as a DNA with a modified sugar moiety (2'-OH instead of the single 2'-H of DNA) or as an RNA with a modified base (thymine (methylated uracil) instead of the uracil of RNA). Thus, the nucleic acid sequences provided herein, including but not limited to those in the sequence listing, are intended to encompass nucleic acids comprising any combination of natural or modified RNA and / or DNA, including, but not limited to, such nucleic acids with modified nucleobases. By way of further example and without limitation, an oligomeric compound having the nucleobase sequence "ATCGATCG," whether modified or unmodified, can be used in combination with such compounds containing RNA bases, such as, but not limited to, those having the sequence "AUCGAUCG," as well as those having some DNA bases and some RNA bases, such as "AUCGATCG." m and oligomeric compounds having other modified nucleobases such as "AACGAUCG", m C denotes a cytosine base containing a methyl group at the 5-position.
[0457] Certain compounds (e.g., modified oligonucleotides) described herein possess one or more asymmetric centers and thus give rise to enantiomers, diastereomers, and other stereoisomeric configurations that can be defined in terms of absolute stereochemistry as (R) or (S), as α or β, such as sugar anomers, or as (D) or (L), such as amino acids. Compounds provided herein depicted or described as having a particular stereoisomeric configuration include only the compound shown. Compounds provided herein depicted or described with undefined stereochemistry include all such possible isomers (including their stereorandom and optically pure forms) unless otherwise specified. Similarly, all cis and trans isomers and tautomeric forms of the compounds herein are included unless otherwise indicated. Oligomeric compounds described herein include chirally pure or enriched mixtures, as well as racemic mixtures. For example, oligomeric compounds having a plurality of phosphorothioate internucleoside linkages include such compounds in which the chirality of the phosphorothioate internucleoside linkages is controlled or random. Unless otherwise indicated, the compounds described herein are intended to include the corresponding salt forms.
[0458] 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 hydrogen atoms include: 1 Isotopic substitutions encompassed by the compounds herein include all possible deuterium substitutions for each H hydrogen atom. 1 Instead of H 2 H or 3 H, 12 Instead of C 13 C or 14 C. 14 Instead of N 15 N, 16 Instead of O 17 O or 18 O, and 32 Instead of S 33 S,34 S, 35 S, or 36 Examples include, but are not limited to, S. In certain embodiments, non-radioactive isotope substitution may impart new properties to oligomeric compounds that are beneficial for use as therapeutic or research tools. In certain embodiments, radioactive isotope substitution may make the compounds suitable for research or diagnostic purposes, such as imaging. [Example]
