[0005] It should be understood that the above summary and the embodiments for carrying out the invention described below are merely illustrative and descriptive, and do not limit the embodiments claimed. The section headings used herein are for illustrative purposes only and should not be construed as limiting the subject matter described.

[0006] All documents or portions of documents cited in this application (including, but not limited to, patents, patent applications, articles, books, papers, GenBank, NCBI, and other sequence reference records) are expressly incorporated herein by reference with respect to the document portions discussed herein and the entirety of this application as of the filing date.

[0007] It should be understood that the sequences shown in each sequence number included herein, even when shown in relation to a modified compound, are independent of any modification to the sugar moiety, nucleoside bond, or nucleic acid base. Therefore, the compounds defined by sequence numbers may independently contain one or more modifications to the sugar moiety, nucleoside bond, or nucleic acid base. The oligomeric compounds referred to by compound numbers or reference numbers indicate a combination of nucleic acid base sequence, chemical modification, and motif.

[0008] In this specification, the use of the singular form includes the plural form unless otherwise specifically indicated. For example, the articles “a” and “an” are used to refer to one or more than one (i.e., at least one) grammatical object of the article. For example, “an + element” means one or more elements, e.g., multiple elements. In this specification, the use of “or” means “and / or” unless otherwise indicated. Furthermore, the use of the term “including,” as well as forms such as “includes” and “included,” is not limiting and is used synonymously with the phrase “including, but not limited to, these.”

Exemplary nucleotide and amino acid sequences of LRRK2 can be found, for example, in nucleotides 5002-149290 of GenBank accession numbers NM_198578.4 (incorporated herein as SEQ ID NO: 1) and NG_011709.2 (incorporated herein as SEQ ID NO: 2). Additional examples of LRRK2 sequences are readily available through publicly available databases, e.g., GenBank, UniProt, and OMIM. Further information on LRRK2 can be found, for example, at www.ncbi.nlm.nih.gov / gene / ?term=LRRK2. As used herein, LRRK2 also refers to variations of the LRRK2 gene (including variants shown in SNP databases). Numerous sequence variations within the LRRK2 gene have been identified and can be found, for example, in NCBI dbSNP and UniProt (see, for example, www.ncbi.nlm.nih.gov / snp / ?term=LRRK2). "LRRK2 mRNA" refers to the mRNA encoding the LRRK2 protein. LRRK2 may be referred to in either uppercase or lowercase.

[0011] An "LRRK2-specific inhibitor" refers to any drug that can specifically inhibit the expression or activity of LRRK2 RNA and / or LRRK2 protein at the molecular level. For example, LRRK2-specific inhibitors include nucleic acids (including oligonucleotide compounds), peptides, antibodies, small molecules, and other drugs that can inhibit the expression of LRRK2 RNA and / or LRRK2 protein.

[0012] "2'-O-methoxyethyl" or "2'-MOE" refers to the modification 2'-O(CH2)2-OCH3. 2'-O-methoxyethyl modified sugars are modified sugars that have 2'-O(CH2)2-OCH3 instead of the 2'-OH group on the ribosyl ring.

[0013] The "5' start site" refers to the nucleotide in the target nucleic acid or target region that aligns with the 3' nucleoside of the antisense oligonucleotide.

[0014] The "3' termination site" refers to the nucleotide in the target nucleic acid or target region that aligns with the furthest 5' nucleoside of the antisense oligonucleotide.

[0015] "Approximately" means a value within ±10%. For example, if it says "a compound that achieved an LRRK2 inhibition rate of approximately 70%", it implies that the LRRK2 level was inhibited within the range of 60% to 80%. When "approximately" precedes a series of numbers or ranges, it should be understood that "approximately" can modify each of those numbers or ranges.

[0016] "Administering" or "administering" refers to a route through which the compounds or compositions provided in this disclosure are introduced into an organism to exert their intended function. Examples of usable administration routes include, but are not limited to, intrathecal (IT) administration, intraventricular (ICV) administration, parenteral administration, such as subcutaneous, intravenous, intramuscular, intra-arterial, intraperitoneal, or intracranial administration, such as intrathecal or intraventricular administration.

Complementary nucleic acid bases are limited to the pairs adenine (A) and thymine (T), adenine (A) and uracil (U), and cytosine (C) and guanine (G), as described herein, unless otherwise specified. 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. In contrast, "perfectly complementary" or "100% complementary," in the case of oligonucleotides, means that the oligonucleotide has nucleic acid base matches at each nucleoside, with no nucleic acid base mismatches whatsoever.

[0021] "Composition" or "pharmaceutical composition" means a mixture of substances suitable for administration to an individual. For example, a composition may contain one or more compounds or salts thereof and a sterile aqueous solution.

[0025] "Identity," in the case of oligonucleotides, means that one or more nucleic acid base sequences within the oligonucleotide or region of that oligonucleotide or region match one or more nucleic acid base sequences within the other oligonucleotide or nucleic acid. Identity between an oligonucleotide and another oligonucleotide or nucleic acid does not require that every nucleic acid base be identical; it may contain one or more different nucleic acid bases. In contrast, "completely identical" or "100% identity," in the case of oligonucleotides, means that the oligonucleotide has the same nucleic acid bases at each corresponding position over its length as the other oligonucleotide or nucleic acid.

[0026] "Individual" refers to a human or non-human animal selected for treatment or therapy.

[0027] "Inhibiting expression or activity" means, with respect to a target nucleic acid or target protein, reducing or blocking the expression or activity of the target compared to the expression or activity in the untreated or control sample, and does not necessarily mean a complete elimination of expression or activity.

[0065] The "targeting portion" refers to a conjugate group that increases the affinity for a given target, such as a molecule, cell or cell type, compartment, such as a compartment of a cell or organ, tissue, organ or region, compared to a compound in which such portion does not exist.

[0066] "Terminal group" refers to the chemical group or atomic group covalently bonded to the end of an oligonucleotide.

[0067] "Therapeutic dose" or "effective dose" means the amount of a compound, pharmaceutical agent, or composition that produces a therapeutic effect on an individual. "Therapeutic dose" or "effective dose" is the amount of a compound sufficient to achieve the stated purpose (e.g., the effect of administering the compound, the effect of treating, preventing, or improving a disease, or the effect of alleviating one or more symptoms of a disease or condition) compared to the absence of the compound. An example of a "therapeutic dose" or "effective dose" is an amount sufficient to contribute to the treatment, prevention, improvement, or alleviation of the symptom(s) of a disease. "Alleviation" of a symptom(s) (and grammatically equivalent phrases) means reducing the severity or frequency of the symptom(s), or eliminating the symptom(s). The “preventive effective dose” of a drug is the amount of the drug administered to a subject that, when administered, produces the intended preventive effect, such as preventing or delaying the onset (or recurrence) of a disorder, disease, condition, or state, or reducing the likelihood of the onset (or recurrence) of a disorder, disease, condition, or state, or its symptoms. The term “therapeutic effective dose,” as used herein, refers to the amount of a therapeutic agent sufficient to produce a therapeutic effect in an individual, such as treating, preventing, or improving a disease, disorder, or its symptoms, as described above. For example, a therapeutic effective dose may show an increase or decrease of at least 5%, 10%, 15%, 20%, 25%, 40%, 50%, 60%, 75%, 80%, 90%, or at least 100% for a given parameter. Therapeutic effectiveness can also be expressed as an increase or decrease of “~ times.” For example, a therapeutic effective dose may show an effect of at least 1.2 times, 1.5 times, 2 times, 5 times, or more than 5 times compared to the control.

[0068] The terms “treating” or “treatment” refer to any sign of success in the therapy or improvement of an injury, disease, condition, or state, which may include any objective or subjective parameter, such as reduction, remission, decrease in symptoms, or increased patient tolerance to the injury, condition, or state, a slower rate of deterioration or decline, a decrease in the degree of debilitation at the end of deterioration, or an improvement in the patient’s physical or mental condition. Treatment or improvement of symptoms may be based on objective or subjective parameters, including the results of a physical examination. The terms “treating” and their inflections may include the prevention of injury, condition, state, or disease. In embodiments, treating is prevention. In embodiments, treating does not include prevention.

[0069] As used herein (and as is well understood in the art), “to treat” or “treatment” broadly includes any approach to obtain a beneficial or desired outcome (including clinical outcomes) in the condition in question. Beneficial or desired clinical outcomes include, but are not limited to, relief or improvement of one or more symptoms or conditions, whether partial or complete, and whether detectable or undetectable; a reduction in the severity of the disease; stabilization of the disease state (i.e., prevention of exacerbation); prevention of disease transmission or spread; delay or slowing of disease progression; improvement or relief of the disease state; reduction of disease relapses; and remission. In other words, as used herein, “treatment” includes curing, improving, or preventing the disease. Treatment may prevent the onset of the disease, inhibit the spread of the disease, reduce the symptoms of the disease, completely or partially eliminate the underlying cause of the disease, shorten the duration of the disease, or a combination of these events.

[0070] As used herein, “to treat” and “treatment” include prophylactic treatment. Treatment involves administering to a subject a therapeutically effective dose of the compounds described herein. This administration step may consist of a single dose or include a series of doses. The duration of treatment depends on various factors, such as the severity of the condition, the patient’s age, the concentration of the compound, the activity of the composition used in treatment, or a combination thereof. It will also be apparent that the effective dose of the drug used for treatment or prevention may increase or decrease over a particular treatment or prophylactic regimen. In some cases, chronic administration may be required. For example, the composition is administered to a subject in an amount and duration sufficient to treat the patient. “To treat” means to administer a compound or pharmaceutical composition to an animal in order to modify or improve a disease, disorder or condition in that animal.

[0071] Certain compounds in this disclosure have an asymmetric carbon atom (optical or chiral center) or a double bond, and the scope of this disclosure includes enantiomers, racemic compounds, diastereomers, tautomers, geometric isomers, stereoisomer forms that may be defined in terms of absolute stereochemistry, such as (R) or (S) or (D) or (L) forms for amino acids, and individual isomers. The compounds in this disclosure do not include compounds that are known in the art to be unstable and unsynthesizable and / or unisolated. This disclosure is intended to include compounds in racemic and optically pure forms. Optically active (R) and (S) or (D) and (L) isomers may be prepared using chiral synthons or chiral reagents, or divided using conventional techniques. When a compound described herein contains an olefin bond or other geometrically asymmetric center, and unless otherwise specified, the compound is intended to include both E and Z geometric isomers.

[0072] As used herein, the term "isomer" refers to a compound having the same number and types of atoms, i.e., the same molecular weight, but differing in the structural arrangement or composition of its atoms.

[0073] As used herein, the term "tautomer" refers to one of two or more structural isomers that exist in equilibrium and are readily convertible from one isomeric form to the other.

[0074] It will be apparent to those skilled in the art that certain compounds of this disclosure may exist in tautomeristic forms, and that any such tautomeristic forms of such compounds fall within the scope of this disclosure.

[0075] Unless otherwise indicated, the structures described herein are intended to include all stereochemical forms (i.e., R and S configurations for each chiral center). Accordingly, single stereochemical isomers of the compounds of the present invention, as well as enantiomer mixtures and diastereomer mixtures, are within the scope of this disclosure.

[0076] As used herein, “chiral-enriched population” means a group of molecules having the same molecular formula, where, if a particular chiral center is stereorandom, the number or percentage of molecules in the population containing a particular stereochemical configuration at that particular chiral center is greater than the number or percentage of molecules in the population that are likely to contain the same particular stereochemical configuration at the same particular chiral center. A group of molecules in a chiral-enriched population, each having multiple chiral centers, may contain one or more stereorandom chiral centers. In certain embodiments, the molecule is a modified oligonucleotide. In certain embodiments, the molecule is a compound containing a modified oligonucleotide.

[0077] Unless otherwise indicated, the structures described herein are also intended to include compounds that differ only in the presence of one or more isotopically enriched atoms. For example, hydrogen may be replaced with deuterium or tritium, or carbon may be replaced with 13 C concentrated carbon or 14 Compounds having the structure of the present invention, except that they are replaced with 13C-enriched carbon, are within the scope of this disclosure.

[0078] As used herein, “stereorandom chiral center” means a chiral center having a random stereochemical configuration with respect to a group of molecules with the same molecular formula. For example, in a group of molecules containing stereorandom chiral centers, the number of molecules having stereorandom chiral centers in (S) configuration may be the same as, but not necessarily the same as, the number of molecules having stereorandom chiral centers in (R) configuration. The stereochemical configuration of a chiral center is considered random when it is the result of a synthetic method not designed to control its stereochemical configuration. In certain embodiments, a stereorandom chiral center is a stereorandom phosphorothioate nucleoside bond.

[0216] Modification and motifs of internucleoside bonds The 3'→5' phosphodiester bond is a natural nucleoside bond in RNA and DNA. In certain embodiments, the compounds described herein have one or more modified nucleoside bonds, i.e., unnatural nucleoside bonds. Certain unnatural nucleoside bonds may confer desirable properties, such as enhanced cellular uptake, increased affinity for target nucleic acids, and improved stability in the presence of nucleases. Representative phosphorus-containing modified nucleoside bonds include, but are not limited to, phosphotriesters, alkylphosphonates (e.g., methylphosphonates), phosphoramidates, and phosphorothioates ("P=S") and phosphorodithioates ("HS-P=S"). Representative non-phosphorus-containing internucleoside bonds include, but are not limited to, methylenemethylimino (-CH2-N(CH3)-O-CH2), thiodiesters, thionocarbamates (-OC(=O)(NH)-S-), siloxanes (-O-SiH2-O-), and N,N'-dimethylhydrazine (-CH2-N((CH3)-N((CH3)-). Methods for preparing phosphorus-containing and non-phosphorus-containing internucleoside bonds are well known to those skilled in the art. Examples of neutral internucleoside bonds include phosphotriesters, methylphosphonates, and MMI(3'-CH2-N(C Examples of neutral internucleoside bonds include, but are not limited to, H3)-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, and thioformacetal(3'-S-CH2-O-5'). Further examples of neutral internucleoside bonds include nonionic bonds, such as siloxanes (dialkylsiloxanes), carboxylic acid esters, carboxamides, sulfides, sulfonic acid esters, and amides (see, for example, Carbohydrate Modifications in Antisense Research; YSSanghvi and PDCook, Eds., ACS Symposium Series 580; Chapters 3 and 4, 40-65).Further examples of neutral nucleoside bonds include nonionic bonds containing mixed N, O, S, and CH2 component parts.

[0217] In certain embodiments, the compounds provided in this disclosure include at least one modified nucleoside bond. The modified nucleoside bond may be located at any of the oligonucleotide positions. In double-stranded compounds, the modified nucleoside bond may be located within the sense oligonucleotide, the antisense oligonucleotide, or both of the oligonucleotides of the double-stranded compound.

[0218] In certain embodiments, the nucleoside-to-nucleoside modification may occur on all nucleosides of the oligonucleotide. In certain embodiments, the nucleoside-to-nucleoside modification may occur in an alternating pattern along the oligonucleotide. In certain embodiments, each nucleoside-to-nucleoside bond is essentially a phosphate nucleoside bond (P=O). In certain embodiments, each nucleoside-to-nucleoside bond in the modified oligonucleotide is a phosphorothioate (P=S). In certain embodiments, each nucleoside-to-nucleoside bond in the modified oligonucleotide is independently selected from phosphorothioate and phosphate nucleoside bonds. In certain embodiments, the pattern of nucleoside-to-nucleoside modification is the same in each oligonucleotide of the double-stranded compound. In certain embodiments, the pattern of nucleoside-to-nucleoside modification is different in each oligonucleotide of the double-stranded compound. In certain embodiments, the double-stranded compound contains 6 to 8 modified nucleoside bonds. In certain embodiments, the 6 to 8 modified nucleoside bonds are phosphorothioate nucleoside bonds or alkylphosphonate nucleoside bonds. In certain embodiments, the sense oligonucleotide contains at least two modified nucleoside bonds at either or both of its 5' and 3' ends. In certain such embodiments, the modified nucleoside bonds are phosphorothioate nucleoside bonds or alkylphosphonate nucleoside bonds. In certain embodiments, the antisense oligonucleotide contains at least two modified nucleoside bonds at either or both of its 5' and 3' ends. In certain such embodiments, the modified nucleoside bonds are phosphorothioate nucleoside bonds or alkylphosphonate nucleoside bonds.

[0219] In certain embodiments, the double-stranded compound includes an overhang region. In certain embodiments, the double-stranded compound includes a phosphorothioate or alkylphosphonate nucleoside linkage modification in its overhang region. In certain embodiments, the double-stranded compound includes a phosphorothioate nucleotide linkage or alkylphosphonate nucleotide linkage that links its overhang nucleotide to the adjacent paired nucleotide. For example, there may be at least two phosphorothioate nucleoside links between three terminal nucleosides, two of which are overhang nucleosides, and the third is the adjacent paired nucleoside. These three terminal nucleosides may be at the 3' end of the antisense oligonucleotide, the 3' end of the sense oligonucleotide, the 5' end of the antisense oligonucleotide, or the 5' end of the antisense oligonucleotide.

[0220] In certain embodiments, the modified oligonucleotide contains one or more nucleoside bonds having a chiral center. Typical chiral nucleoside bonds include, but are not limited to, alkylphosphonates and phosphorothioates. Modified oligonucleotides containing nucleoside bonds having a chiral center can be prepared in a specific stereochemical configuration as a group of modified oligonucleotides containing stereorandom nucleoside bonds or as a group of modified oligonucleotides containing phosphorothioate bonds. In certain embodiments, the group of modified oligonucleotides contains phosphorothioate nucleoside bonds, all of which are stereorandom. Such modified oligonucleotides can be produced using a synthetic method that randomly selects the stereochemical configuration of each phosphorothioate bond. As will be well understood by those skilled in the art, each individual phosphorothioate of 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 nucleoside bonds in a specific, independently selected stereochemical configuration. In certain embodiments, the specific configuration of the particular phosphorothioate bond is present in at least 65% of the molecules in the population. In certain embodiments, the specific configuration of the particular phosphorothioate bond is present in at least 70% of the molecules in the population. In certain embodiments, the specific configuration of the particular phosphorothioate bond is present in at least 80% of the molecules in the population. In certain embodiments, the specific configuration of the particular phosphorothioate bond is present in at least 90% of the molecules in the population. In certain embodiments, the specific configuration of the particular phosphorothioate bond is present in at least 99% of the molecules in the population. Such enriched populations of modified oligonucleotides can be produced using synthetic methods known in the art, for example, the methods described in Oka et al., JACS 125, 8307 (2003), Wan et al. Nuc. Acid. Res. 42, 13456 (2014), and WO2017 / 015555.In certain embodiments, the population of modified oligonucleotides is enriched with respect to modified oligonucleotides having at least one phosphorothioate in the (Sp) conformation. In certain embodiments, the population of modified oligonucleotides is enriched with respect to modified oligonucleotides having at least one phosphorothioate in the (Rp) conformation.

[0228] The conjugate group may be linked to the oligonucleotide via a conjugate linker. In certain embodiments, the conjugate linker includes a chain structure, such as a hydrocarbyl chain, or an oligomer of repeating units or a combination of such repeating units.

In certain embodiments, the conjugate linker comprises 1 to 10 linker-nucleosides. In certain embodiments, such linker-nucleosides may be modified or unmodified nucleosides. It is typically desirable that the linker-nucleosides be cleaved from the compound once the compound reaches the target tissue. Thus, the linker-nucleosides in the present invention can be linked to each other and to the remainder of the compound via cleavable bonds. In the present invention, linker-nucleosides are not considered to be part of their oligonucleotides. Therefore, in embodiments in which a compound comprises an oligonucleotide consisting of a predetermined number or range of linked nucleosides and / or an oligonucleotide having a predetermined complementarity percentage to a reference nucleic acid, and in embodiments in which the compound also comprises a conjugate group including a conjugate linker containing a linker nucleoside, these linker nucleosides are not counted in relation to the length of the oligonucleotide and are not used when determining the complementarity percentage of the oligonucleotide with respect to the reference nucleic acid.

In certain embodiments, the target nucleic acid is non-coding. In certain such embodiments, the target nucleic acid is selected from mRNA and premRNA (including intron, exon, and untranslated regions). In certain embodiments, the target RNA is mRNA. In certain embodiments, the target nucleic acid is premRNA. In certain such embodiments, the target region is entirely within an exon. In certain such embodiments, the target region is entirely within an intron. In certain embodiments, the target region extends to an intron junction / exon junction. In certain embodiments, at least 50% of the target region is within an intron.

[0265] In certain embodiments, the compounds disclosed herein hybridize with LRRK2 nucleic acids. The most common hybridization mechanism involves hydrogen bonding between complementary nucleic acid bases of those nucleic acid molecules. Hybridization can occur under a variety of conditions. Hybridization conditions are sequence-dependent and are determined by the properties and composition of the nucleic acid molecules hybridizing. Methods for determining whether a sequence specifically hybridizes with a target nucleic acid are well known in the art. In certain embodiments, the compounds provided herein specifically hybridize with LRRK2 nucleic acids.

[0266] Examples of nucleotide sequences encoding LRRK2 include, but are not limited to, GenBank accession number NM_198578.4 (incorporated herein as SEQ ID NO: 1) and nucleotides 5002-149290 of NG_011709.2 (incorporated herein as SEQ ID NO: 2).

[0267] Complementarity Oligonucleotides provided in this disclosure may have defined percentages of complementarity to specific nucleic acids, target regions, oligonucleotides, or parts thereof. Non-complementary nucleic acid bases may be permitted, provided that the oligonucleotide remains capable of specifically hybridizing to the nucleic acid, oligonucleotide, or part thereof. In certain embodiments, an oligonucleotide or a given part thereof provided in this disclosure is at least 70%, 80%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% complementary to a target nucleic acid, target region, oligonucleotide, or a given part thereof. In certain embodiments, an oligonucleotide or a specified portion thereof provided in this disclosure is complementary to a target nucleic acid, target region, oligonucleotide or a specified portion thereof by 70%-75%, 75%-80%, 80%-85%, 85%-90%, 90%-95%, 95%-100%, or any number in between these ranges. The complementarity percentage between an oligonucleotide and a target nucleic acid, target region, oligonucleotide or a specified portion thereof can be determined by a conventional method. For example, an oligonucleotide that specifically hybridizes because 18-20 nucleic acid bases of that oligonucleotide are complementary to the target region will have a complementarity percentage of 90. In this example, the remaining non-complementary nucleic acid bases may be clustered with complementary nucleic acid bases or scattered among complementary nucleic acid bases, and do not need to be consecutive with each other or with complementary nucleic acid bases. Therefore, an oligonucleotide with a nucleic acid base length of 18 and four non-complementary nucleic acid bases flanked by two regions that are perfectly complementary to the target nucleic acid will have an overall complementarity of 77.8% with respect to the target nucleic acid. The complementarity percentage of an oligonucleotide with respect to the target nucleic acid, target region, oligonucleotide, or a predetermined region of the oligonucleotide can be determined by a standard method using the BLAST program (Basic Local Alignment Search Tool), which is known in the art.In certain embodiments, an oligonucleotide or a given portion thereof described herein is fully complementary (i.e., 100% complementary) to a target nucleic acid, a target region, an oligonucleotide, or a given portion thereof. For example, an oligonucleotide may be fully complementary to a target nucleic acid, a target region, an oligonucleotide, or a given portion thereof. As used herein, “fully complementary” means that each nucleic acid base of the oligonucleotide is complementary to the corresponding nucleic acid base of the target nucleic acid, a target region, an oligonucleotide, or a given portion thereof. For example, a 20-nucleotide oligonucleotide is fully complementary to a 400-nucleotide-length target sequence, as long as there are 20 corresponding nucleic acid base portions of the target nucleic acid that are fully complementary to the compound. “Fully complementary” can also be used with respect to a given portion of the first and / or second nucleic acid. For example, a 20-nucleotide portion of a 30-nucleotide oligonucleotide may be “fully complementary” to a 20-nucleotide region of a 400-nucleotide-length target sequence. The 20-nucleotide portion of the 30-nucleotide compound is perfectly complementary to its target sequence if the target sequence has a corresponding 20-nucleotide portion and each nucleotide 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 its target sequence, depending on whether the remaining 10 nucleotides of the compound are also complementary to its target sequence.

[0268] In certain embodiments, the oligonucleotides described herein contain one or more mismatched nucleic acid bases with respect to a target nucleic acid, a target region, an oligonucleotide, or a predetermined portion thereof.

[0270] identity Oligonucleotides provided herein may have defined identity percentages with respect to specific nucleic acids, target regions, oligonucleotides, or predetermined portions thereof. For use herein, oligonucleotides are identical to sequences disclosed herein if they have the same nucleic acid base-pairing ability. For example, a DNA containing thymidine instead of uracil in the disclosed RNA sequence will be considered identical to the RNA sequence because both uracil and thymidine pair with adenine. Shortened and extended forms of the compounds described herein, as well as compounds having bases that are not identical to the compounds provided herein, are also envisioned. These non-identical bases may be adjacent to each other or scattered throughout the compound. The identity percentage of an oligonucleotide is calculated according to the number of bases that have identical base-pairing properties with respect to the sequence being compared. In certain embodiments, an oligonucleotide or a portion thereof described herein is 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% identical to one or more nucleic acids, oligonucleotides or portions thereof disclosed herein, or at least 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% identical.
