[0022] I. Definitions

[0023] The abbreviations used herein have their conventional meaning within the chemical and biological arts. The chemical structures and formulae set forth herein are constructed according to the standard rules of chemical valency known in the chemical arts. [0024] Where substituent groups are specified by their conventional chemical formulae, written from left to right, they equally encompass the chemically identical substituents that would result from writing the structure from right to left, e.g., -CH₂0- is equivalent to -OCH₂-. [0025] The term "alkyl," by itself or as part of another substituent, means, unless otherwise stated, a straight (i.e., unbranched) or branched carbon chain (or carbon), or combination thereof, which may be fully saturated, mono- or polyunsaturated and can include di- and multivalent radicals, having the number of carbon atoms designated (i.e., Ci-Cio means one to ten carbons). Alkyl is not cyclized. Examples of saturated hydrocarbon radicals include, but are not limited to, groups such as methyl, ethyl, n-propyl, isopropyl, n-butyl, t-butyl, isobutyl, sec-butyl, homologs and isomers of, for example, n-pentyl, n-hexyl, n-heptyl, n-octyl, and the like. An unsaturated alkyl group is one having one or more double bonds or triple bonds (e.g. alkene, alkyne).

Examples of unsaturated alkyl groups include, but are not limited to, vinyl, 2-propenyl, crotyl, 2- isopentenyl, 2-(butadienyl), 2,4-pentadienyl, 3-(l,4-pentadienyl), ethynyl, 1- and 3-propynyl, 3- butynyl, and the higher homologs and isomers. An alkoxy is an alkyl attached to the remainder of the molecule via an oxygen linker (-0-). An alkyl moiety may be an alkenyl moiety. An alkyl moiety may be an alkynyl moiety. An alkyl moiety may be fully saturated.

[0026] The term "alkylene," by itself or as part of another substituent, means, unless otherwise stated, a divalent radical derived from an alkyl, as exemplified, but not limited by,

-CH₂CH₂CH₂CH₂-. Typically, an alkyl (or alkylene) group will have from 1 to 24 carbon atoms, with those groups having 10 or fewer carbon atoms being preferred in the present invention. A "lower alkyl" or "lower alkylene" is a shorter chain alkyl or alkylene group, generally having eight or fewer carbon atoms. The term "alkenylene," by itself or as part of another substituent, means, unless otherwise stated, a divalent radical derived from an alkene.

[0027] The term "heteroalkyl," by itself or in combination with another term, means, unless otherwise stated, a stable straight or branched chain, or combinations thereof, including at least one carbon atom and at least one heteroatom (e.g., O, N, P, Si, or S), and wherein the nitrogen and sulfur atoms may optionally be oxidized, and the nitrogen heteroatom may optionally be quaternized. The heteroatom(s) (e.g., O, N, P, S, B, As, or Si) may be placed at any interior position of the heteroalkyl group or at the position at which the alkyl group is attached to the remainder of the molecule. Heteroalkyl is an uncyclized chain. Examples include, but are not limited to: -CH₂-CH₂-0-CH₃, -CH₂-CH₂- H-CH₃, -CH₂-CH₂-N(CH₃)-CH₃, -CH₂-S-CH₂-CH₃, - CH₂-CH₂, -S(0)-CH₃, -CH₂-CH₂-S(0)₂-CH₃, -CH=CH-0-CH₃, -Si(CH₃)₃, -CH₂-CH=N-OCH₃, - CH=CH-N(CH₃)-CH₃, -0-CH₃, -0-CH₂-CH₃, and -CN. Up to two or three heteroatoms may be consecutive, such as, for example, -CH₂- H-OCH₃ and -CH₂-0-Si(CH₃)₃. A heteroalkyl moiety may include one heteroatom (e.g., O, N, S, Si, or P). A heteroalkyl moiety may include two optionally different heteroatoms (e.g., O, N, S, Si, or P). A heteroalkyl moiety may include three optionally different heteroatoms (e.g., O, N, S, Si, or P). A heteroalkyl moiety may include four optionally different heteroatoms (e.g., O, N, S, Si, or P). A heteroalkyl moiety may include five optionally different heteroatoms (e.g., O, N, S, Si, or P). A heteroalkyl moiety may include up to

8 optionally different heteroatoms (e.g., O, N, S, Si, or P).

[0028] Similarly, the term "heteroalkylene," by itself or as part of another substituent, means, unless otherwise stated, a divalent radical derived from heteroalkyl, as exemplified, but not limited by, -CH₂-CH₂-S-CH₂-CH₂- and -CH₂-S-CH₂-CH₂- H-CH₂-. For heteroalkylene groups, heteroatoms can also occupy either or both of the chain termini (e.g., alkyleneoxy, alkylenedioxy, alkyleneamino, alkylenediamino, and the like). Still further, for alkylene and heteroalkylene linking groups, no orientation of the linking group is implied by the direction in which the formula of the linking group is written. For example, the formula -C(0)₂R'- represents both - C(0)₂R'- and -R'C(0)₂-. As described above, heteroalkyl groups, as used herein, include those groups that are attached to the remainder of the molecule through a heteroatom, such as -C(0)R, -C(0) R', - R'R", -OR, -SR, and/or -S0₂R. Where "heteroalkyl" is recited, followed by recitations of specific heteroalkyl groups, such as -NR'R" or the like, it will be understood that the terms heteroalkyl and -NR'R" are not redundant or mutually exclusive. Rather, the specific heteroalkyl groups are recited to add clarity. Thus, the term "heteroalkyl" should not be interpreted herein as excluding specific heteroalkyl groups, such as -NR'R" or the like.

[0029] The terms "cycloalkyl" and "heterocycloalkyl," by themselves or in combination with other terms, mean, unless otherwise stated, non-aromatic cyclic versions of "alkyl" and

"heteroalkyl," respectively, wherein the carbons making up the ring or rings do not necessarily need to be bonded to a hydrogen due to all carbon valencies participating in bonds with non- hydrogen atoms. Additionally, for heterocycloalkyl, a heteroatom can occupy the position at which the heterocycle is attached to the remainder of the molecule. Examples of cycloalkyl include, but are not limited to, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, 1-cyclohexenyl, 3-cyclohexenyl, cycloheptyl, 3-hydroxy-cyclobut-3-enyl-l,2, dione, lH-l,2,4-triazolyl-5(4H)- one, 4H-l,2,4-triazolyl, and the like. Examples of heterocycloalkyl include, but are not limited to, l-(l,2,5,6-tetrahydropyridyl), 1-piperidinyl, 2-piperidinyl, 3-piperidinyl, 4-morpholinyl, 3- morpholinyl, tetrahydrofuran-2-yl, tetrahydrofuran-3-yl, tetrahydrothien-2-yl, tetrahydrothien-3 - yl, 1-piperazinyl, 2-piperazinyl, and the like. A "cycloalkyl ene" and a "heterocycloalkyl ene," alone or as part of another substituent, means a divalent radical derived from a cycloalkyl and heterocycloalkyl, respectively. A heterocycloalkyl moiety may include one ring heteroatom (e.g., O, N, S, Si, or P). A heterocycloalkyl moiety may include two optionally different ring heteroatoms (e.g., O, N, S, Si, or P). A heterocycloalkyl moiety may include three optionally different ring heteroatoms (e.g., O, N, S, Si, or P). A heterocycloalkyl moiety may include four optionally different ring heteroatoms (e.g., O, N, S, Si, or P). A heterocycloalkyl moiety may include five optionally different ring heteroatoms (e.g., O, N, S, Si, or P). A heterocycloalkyl moiety may include up to 8 optionally different ring heteroatoms (e.g., O, N, S, Si, or P).

[0030] The terms "halo" or "halogen," by themselves or as part of another substituent, mean, unless otherwise stated, a fluorine, chlorine, bromine, or iodine atom. Additionally, terms such as "haloalkyl" are meant to include monohaloalkyl and polyhaloalkyl. For example, the term "halo(Ci-C₄)alkyl" includes, but is not limited to, fluoromethyl, difluoromethyl, trifluoromethyl, 2,2,2-trifluoroethyl, 4-chlorobutyl, 3-bromopropyl, and the like.

[0031] The term "acyl" means, unless otherwise stated, -C(0)R where R is a substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, or substituted or unsubstituted heteroaryl.

[0032] The term "aryl" means, unless otherwise stated, a polyunsaturated, aromatic, hydrocarbon substituent, which can be a single ring or multiple rings (preferably from 1 to 3 rings) that are fused together (i.e., a fused ring aryl) or linked covalently. A fused ring aryl refers to multiple rings fused together wherein at least one of the fused rings is an aryl ring. The term "heteroaryl" refers to aryl groups (or rings) that contain at least one heteroatom such as N, O, or S, wherein the nitrogen and sulfur atoms are optionally oxidized, and the nitrogen atom(s) are optionally quaternized. Thus, the term "heteroaryl" includes fused ring heteroaryl groups (i.e., multiple rings fused together wherein at least one of the fused rings is a heteroaromatic ring). A 5,6-fused ring heteroarylene refers to two rings fused together, wherein one ring has 5 members and the other ring has 6 members, and wherein at least one ring is a heteroaryl ring. Likewise, a 6,6-fused ring heteroarylene refers to two rings fused together, wherein one ring has 6 members and the other ring has 6 members, and wherein at least one ring is a heteroaryl ring. And a 6,5- fused ring heteroarylene refers to two rings fused together, wherein one ring has 6 members and the other ring has 5 members, and wherein at least one ring is a heteroaryl ring. A heteroaryl group can be attached to the remainder of the molecule through a carbon or heteroatom. Non- limiting examples of aryl and heteroaryl groups include phenyl, 1-naphthyl, 2-naphthyl, 4- biphenyl, 1 -pyrrol yl, 2-pyrrolyl, 3 -pyrrol yl, 3-pyrazolyl, 2-imidazolyl, 4-imidazolyl, pyrazinyl, 2- oxazolyl, 4-oxazolyl, 2-phenyl-4-oxazolyl, 5-oxazolyl, 3-isoxazolyl, 4-isoxazolyl, 5-isoxazolyl, 2-thiazolyl, 4-thiazolyl, 5-thiazolyl, 2-furyl, 3-furyl, 2-thienyl, 3-thienyl, 2-pyridyl, 3-pyridyl, 4- pyridyl, 2-pyrimidyl, 4-pyrimidyl, 5-benzothiazolyl, purinyl, 2-benzimidazolyl, 5-indolyl, 1- isoquinolyl, 5-isoquinolyl, 2-quinoxalinyl, 5-quinoxalinyl, 3-quinolyl, and 6-quinolyl.

Substituents for each of the above noted aryl and heteroaryl ring systems are selected from the group of acceptable substituents described below. An "arylene" and a "heteroarylene," alone or as part of another substituent, mean a divalent radical derived from an aryl and heteroaryl, respectively. Non-limiting examples of aryl and heteroaryl groups include pyridinyl,

pyrimidinyl, thiophenyl, thienyl, furanyl, indolyl, benzoxadiazolyl, benzodioxolyl,

benzodioxanyl, thianaphthanyl, pyrrolopyridinyl, indazolyl, quinolinyl, quinoxalinyl,

The examples above may be substituted or unsubstituted and divalent radicals of each heteroaryl example above are non-limiting examples of heteroaryl ene. A heteroaryl moiety may include one ring heteroatom (e.g., O, N, or S). A heteroaryl moiety may include two optionally different ring heteroatoms (e.g., O, N, or S). A heteroaryl moiety may include three optionally different ring heteroatoms (e.g., O, N, or S). A heteroaryl moiety may include four optionally different ring heteroatoms (e.g., O, N, or S). A heteroaryl moiety may include five optionally different ring heteroatoms (e.g., O, N, or S). An aryl moiety may have a single ring. An aryl moiety may have two optionally different rings. An aryl moiety may have three optionally different rings. An aryl moiety may have four optionally different rings. A heteroaryl moiety may have one ring. A heteroaryl moiety may have two optionally different rings. A heteroaryl moiety may have three optionally different rings. A heteroaryl moiety may have four optionally different rings. A heteroaryl moiety may have five optionally different rings.

[0033] A fused ring heterocyloalkyl-aryl is an aryl fused to a heterocycloalkyl. A fused ring heterocycloalkyl -heteroaryl is a heteroaryl fused to a heterocycloalkyl. A fused ring

heterocycloalkyl-cycloalkyl is a heterocycloalkyl fused to a cycloalkyl. A fused ring

heterocycloalkyl-heterocycloalkyl is a heterocycloalkyl fused to another heterocycloalkyl. Fused ring heterocycloalkyl-aryl, fused ring heterocycloalkyl-heteroaryl, fused ring heterocycloalkyl- cycloalkyl, or fused ring heterocycloalkyl-heterocycloalkyl may each independently be unsubstituted or substituted with one or more of the substituents described herein. [0034] The term "oxo," as used herein, means an oxygen that is double bonded ("=0") to a carbon atom.

[0035] The term "alkylsulfonyl," as used herein, means a moiety having the formula -S(0₂)-R', where R' is a substituted or unsubstituted alkyl group as defined above. R may have a specified number of carbons (e.g., "C₁-C₄ alkylsulfonyl"). [0036] Each of the above terms (e.g., "alkyl," "heteroalkyl,", "cycloalkyl", "heterocycloalkyl",

"aryl," and "heteroaryl") includes both substituted and unsubstituted forms of the indicated radical.

[0037] Substituents for the alkyl and heteroalkyl radicals (including those groups often referred to as alkylene, alkenyl, heteroalkylene, heteroalkenyl, alkynyl, cycloalkyl, heterocycloalkyl, cycloalkenyl, and heterocycloalkenyl) can be one or more of a variety of groups selected from, but not limited to, -OR', =0, = R', =N-OR, - R'R", -SR, -halogen, -SiRR'R", -OC(0)R, - C(0)R, -C0₂R, -CO R'R", -OC(0) R'R", - R"C(0)R, - R'-C(0) R"R", - R"C(0)₂R, -NR- C( R'R")= R"', -S(0)R, -S(0)₂R, -S(0)₂N(R)('R"- RS0₂R), -CN, and -N0₂ in a number ranging from zero to (2m'+l), where m' is the total number of carbon atoms in such radical. R, R", R", and R"" each preferably independently refer to hydrogen, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl (e.g., aryl substituted with 1-3 halogens), substituted or unsubstituted alkyl, alkoxy, or thioalkoxy groups, or arylalkyl groups. When a compound of the invention includes more than one R group, for example, each of the R groups is independently selected as are each R, R", R", and R"" group when more than one of these groups is present. When R and R" are attached to the same nitrogen atom, they can be combined with the nitrogen atom to form a 4-, 5-, 6-, or 7-membered ring. For example, -NR'R" includes, but is not limited to, 1-pyrrolidinyl and 4-morpholinyl. From the above discussion of substituents, one of skill in the art will understand that the term "alkyl" is meant to include groups including carbon atoms bound to groups other than hydrogen groups, such as haloalkyl (e.g., -CF₃ and -CH₂CF₃) and acyl (e.g., -C(0)CH₃, -C(0)CF₃, -C(0)CH₂OCH₃, and the like).

[0038] Similar to the substituents described for the alkyl radical, substituents for the aryl and heteroaryl groups are varied and are selected from, for example: -OR, -NR'R", -SR, -halogen, - SiRR'R", -OC(0)R, -C(0)R, -C0₂R, -CONR'R", -OC(0)NR'R", -NR"C(0)R, -NR'-

C(0)NR"R", NR"C(0)₂R, NRC(NR'R")=NR"', S(0)R, -S(0)₂R, -S(0)₂N(R')(R", -NRS0₂R), - CN, -N0₂, -R, -N₃, -CH(Ph)₂, fluoro(Ci-C₄)alkoxy, and fluoro(Ci-C₄)alkyl, in a number ranging from zero to the total number of open valences on the aromatic ring system; and where R, R", R", and R"" are preferably independently selected from hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, and substituted or

unsubstituted heteroaryl. When a compound of the invention includes more than one R group, for example, each of the R groups is independently selected as are each R, R", R", and R"" groups when more than one of these groups is present. [0039] Where a moiety is substituted with an R substituent, the group may be referred to as "R- substituted." Where a moiety is R- substituted, the moiety is substituted with at least one R substituent and each R substituent is optionally different. For example, where a moiety herein is R^1A-substituted or unsubstituted alkyl, a plurality of R^1A substituents may be attached to the alkyl moiety wherein each R^1A substituent is optionally different. Where an R-substituted moiety is substituted with a plurality R substituents, each of the R-substituents may be differentiated herein using a prime symbol (') such as R, R", etc. For example, where a moiety is R^1A-substituted or unsubstituted alkyl, and the moiety is substituted with a plurality of R^1A substituents, the plurality of R^1A substituents may be differentiated as R^1A|, R^1A", R^1A|", etc. In some embodiments, the plurality of R substituents is 3. In some embodiments, the plurality of R substituents is 2.

[0040] In embodiments, a compound as described herein may include multiple instances of R¹, R², and/or other substituents and variables. In such embodiments, each variable may optional be different and be appropriately labeled to distinguish each group for greater clarity. For example, where each R^6A is different, they may be referred to, for example, as R^{6A Λ}, R^{6A 2}, R^{6A 3}, or R^{6A 4}, respectively, wherein the definition of R^6A is assumed by R^6A R^{6A 2}, R^{6A 3}, and/or R^{6A 4}. The variables used within a definition of R¹, R², and/or other variables that appear at multiple instances and are different may similarly be appropriately labeled to distinguish each group for greater clarity.

[0041] Two or more substituents may optionally be joined to form aryl, heteroaryl, cycloalkyl, or heterocycloalkyl groups. Such so-called ring-forming substituents are typically, though not necessarily, found attached to a cyclic base structure. In one embodiment, the ring-forming substituents are attached to adjacent members of the base structure. For example, two ring- forming substituents attached to adjacent members of a cyclic base structure create a fused ring structure. In embodiments, the ring-forming substituents are attached to a single member of the base structure. For example, two ring-forming substituents attached to a single member of a cyclic base structure create a spirocyclic structure. In yet another embodiment, the ring-forming substituents are attached to non-adjacent members of the base structure.

[0042] Two of the substituents on adjacent atoms of the aryl or heteroaryl ring may optionally form a ring of the formula -T-C(0)-(CRR')_q-U-, wherein T and U are independently - R-, -0-, -CRR-, or a single bond, and q is an integer of from 0 to 3. Alternatively, two of the substituents on adjacent atoms of the aryl or heteroaryl ring may optionally be replaced with a substituent of the formula -A-(CH₂)_r-B-, wherein A and B are independently -CRR-, -0-, - R-, -S-, -S(O) -, -S(0)₂-, -S(0)₂NR'-, or a single bond, and r is an integer of from 1 to 4. One of the single bonds of the new ring so formed may optionally be replaced with a double bond. Alternatively, two of the substituents on adjacent atoms of the aryl or heteroaryl ring may optionally be replaced with a substituent of the formula -(CRR')_S-X'- (C"R"R"')_d-, where variables s and d are independently integers of from 0 to 3, and X' is -0-, - R'-, -S-, -S(O)-, -S(0)₂-, or -S(0)₂ R'-. The substituents

R, R, R", and R" are preferably independently selected from hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, and substituted or unsubstituted heteroaryl.

[0050] The term "pharmaceutically acceptable salts" is meant to include salts of the active compounds that are prepared with relatively nontoxic acids or bases, depending on the particular substituents found on the compounds described herein. When compounds of the present invention contain relatively acidic functionalities, base addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired base, either neat or in a suitable inert solvent. Examples of pharmaceutically acceptable base addition salts include sodium, potassium, calcium, ammonium, organic amino, or magnesium salt, or a similar salt. When compounds of the present invention contain relatively basic functionalities, acid addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired acid, either neat or in a suitable inert solvent. Examples of pharmaceutically acceptable acid addition salts include those derived from inorganic acids like hydrochloric, hydrobromic, nitric, carbonic, monohydrogencarbonic, phosphoric,

monohydrogenphosphoric, dihydrogenphosphoric, sulfuric, monohydrogensulfuric, hydriodic, or phosphorous acids and the like, as well as the salts derived from relatively nontoxic organic acids like acetic, propionic, isobutyric, maleic, malonic, benzoic, succinic, suberic, fumaric, lactic, mandelic, phthalic, benzenesulfonic, p-tolyl sulfonic, citric, tartaric, methanesulfonic, and the like. Also included are salts of amino acids such as arginate and the like, and salts of organic acids like glucuronic or galactunoric acids and the like (see, e.g., Berge et al, Journal of

Pharmaceutical Science 66: 1-19 (1977)). Certain specific compounds of the present invention contain both basic and acidic functionalities that allow the compounds to be converted into either base or acid addition salts. Other pharmaceutically acceptable carriers known to those of skill in the art are suitable for the present invention. Salts tend to be more soluble in aqueous or other protonic solvents that are the corresponding free base forms. In other cases, the preparation may be a lyophilized powder in 1 mM-50 mM histidine, 0.1%-2% sucrose, 2%-7% mannitol at a pH range of 4.5 to 5.5, that is combined with buffer prior to use.

[0051] Thus, the compounds of the present invention may exist as salts, such as with pharmaceutically acceptable acids. The present invention includes such salts. Examples of such salts include hydrochlorides, hydrobromides, sulfates, methanesulfonates, nitrates, maleates, acetates, citrates, fumarates, tartrates (e.g., (+)-tartrates, (-)-tartrates, or mixtures thereof including racemic mixtures), succinates, benzoates, and salts with amino acids such as glutamic acid. These salts may be prepared by methods known to those skilled in the art.

[0052] The neutral forms of the compounds are preferably regenerated by contacting the salt with a base or acid and isolating the parent compound in the conventional manner. The parent form of the compound differs from the various salt forms in certain physical properties, such as solubility in polar solvents. [0053] Provided herein are agents (e.g. compounds, drugs, therapeutic agents) that may be in a prodrug form. Prodrugs of the compounds described herein are those compounds that readily undergo chemical changes under select physiological conditions to provide the final agents (e.g. compounds, drugs, therapeutic agents). Additionally, prodrugs can be converted to agents (e.g. compounds, drugs, therapeutic agents) by chemical or biochemical methods in an ex vivo environment. Prodrugs described herein include compounds that readily undergo chemical changes under select physiological conditions to provide agents (e.g. compounds, drugs, therapeutic agents) to a biological system (e.g. in a subject, in a cell, in the extracellular space near a cell). [0054] Certain compounds of the present invention can exist in unsolvated forms as well as solvated forms, including hydrated forms. In general, the solvated forms are equivalent to unsolvated forms and are encompassed within the scope of the present invention. Certain compounds of the present invention may exist in multiple crystalline or amorphous forms. In general, all physical forms are equivalent for the uses contemplated by the present invention and are intended to be within the scope of the present invention.

[0055] As used herein, the term "salt" refers to acid or base salts of the compounds used in the methods of the present invention. Illustrative examples of acceptable salts are mineral acid (hydrochloric acid, hydrobromic acid, phosphoric acid, and the like) salts, organic acid (acetic acid, propionic acid, glutamic acid, citric acid and the like) salts, quaternary ammonium (methyl iodide, ethyl iodide, and the like) salts.

[0056] Certain compounds of the present invention possess asymmetric carbon atoms (optical or chiral centers) or double bonds; the enantiomers, racemates, diastereomers, tautomers, geometric isomers, stereoisometric forms that may be defined, in terms of absolute

stereochemistry, as (R)-or (S)- or, as (D)- or (L)- for amino acids, and individual isomers are encompassed within the scope of the present invention. The compounds of the present invention do not include those which are known in art to be too unstable to synthesize and/or isolate. The present invention is meant 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 resolved using conventional techniques. When the compounds described herein contain olefinic bonds or other centers of geometric asymmetry, and unless specified otherwise, it is intended that the compounds include both E and Z geometric isomers.

[0057] As used herein, the term "isomers" refers to compounds having the same number and kind of atoms, and hence the same molecular weight, but differing in respect to the structural arrangement or configuration of the atoms. [0058] The term "tautomer," as used herein, refers to one of two or more structural isomers which exist in equilibrium and which are readily converted from one isomeric form to another.

[0059] It will be apparent to one skilled in the art that certain compounds of this invention may exist in tautomeric forms, all such tautomeric forms of the compounds being within the scope of the invention.

[0060] Unless otherwise stated, structures depicted herein are also meant to include all stereochemical forms of the structure; i.e., the R and S configurations for each asymmetric center. Therefore, single stereochemical isomers as well as enantiomeric and diastereomeric mixtures of the present compounds are within the scope of the invention. [0061] Unless otherwise stated, structures depicted herein are also meant to include compounds which differ only in the presence of one or more isotopically enriched atoms. For example, compounds having the present structures except for the replacement of a hydrogen by a deuterium or tritium, or the replacement of a carbon by ¹³C- or ¹⁴C-enriched carbon are within the scope of this invention. [0062] The compounds of the present invention may also contain unnatural proportions of atomic isotopes at one or more of the atoms that constitute such compounds. For example, the compounds may be radiolabeled with radioactive isotopes, such as for example tritium (³H), iodine-125 (¹²⁵I), or carbon-14 (¹⁴C). All isotopic variations of the compounds of the present invention, whether radioactive or not, are encompassed within the scope of the present invention. [0063] The symbol "JW" denotes the point of attachment of a chemical moiety to the remainder of a molecule or chemical formula.

[0064] The terms "treating", or "treatment" refers to any indicia of success in the therapy or amelioration of an injury, disease, pathology or condition, including any objective or subjective parameter such as abatement; remission; diminishing of symptoms or making the injury, pathology or condition more tolerable to the patient; slowing in the rate of degeneration or decline; making the final point of degeneration less debilitating; improving a patient's physical or mental well-being. The treatment or amelioration of symptoms can be based on objective or subjective parameters; including the results of a physical examination, neuropsychiatric exams, and/or a psychiatric evaluation. The term "treating" and conjugations thereof, may include prevention of an injury, pathology, condition, or disease. In embodiments, treating is preventing. In embodiments, treating does not include preventing.

[0065] An "effective amount" is an amount sufficient for a compound to accomplish a stated purpose relative to the absence of the compound (e.g. achieve the effect for which it is administered, treat a disease, reduce enzyme activity, increase enzyme activity, reduce a signaling pathway, or reduce one or more symptoms of a disease or condition). An example of an "therapeutically effective amount" is an amount sufficient to contribute to the treatment, prevention, or reduction of a symptom or symptoms of a disease, which could also be referred to as a "therapeutically effective amount." A "reduction" of a symptom or symptoms (and grammatical equivalents of this phrase) means decreasing of the severity or frequency of the symptom(s), or elimination of the symptom(s). The exact amounts will depend on the purpose of the treatment, and will be ascertainable by one skilled in the art using known techniques (see, e.g., Lieberman, Pharmaceutical Dosage Forms (vols. 1-3, 1992); Lloyd, The Art, Science and Technology of Pharmaceutical Compounding (1999); Pickar, Dosage Calculations (1999); and Remington: The Science and Practice of Pharmacy, 20th Edition, 2003, Gennaro, Ed.,

Lippincott, Williams & Wilkins).

[0066] The term "associated" or "associated with" in the context of a substance or substance activity or function associated with a disease (e.g. infectious disease, hyperproliferative disease, cancer) means that the disease is caused by (in whole or in part), or a symptom of the disease is caused by (in whole or in part) the substance or substance activity or function. As used herein, what is described as being associated with a disease, if a causative agent, could be a target for treatment of the disease. For example, a disease associated with infection may be treated with an agent (e.g. compound as described herein) effective as an antibiotic. [0067] As used herein, the term "cancer" refers to all types of cancer, neoplasm, or malignant tumors found in mammals, including leukemia, carcinomas and sarcomas. Exemplary cancers include cancer of the brain, breast, cervix, colon, head & neck, liver, kidney, lung, non-small cell lung, melanoma, mesothelioma, ovary, sarcoma, stomach, uterus and Medulloblastoma.

Additional examples include, metastatic bone cancer, Hodgkin's Disease, Non-Hodgkin's Lymphoma, multiple myeloma, neuroblastoma, ovarian cancer, rhabdomyosarcoma, primary thrombocytosis, primary macroglobulinemia, primary brain tumors, cancer, malignant pancreatic insulanoma, malignant carcinoid, urinary bladder cancer, premalignant skin lesions, testicular cancer, lymphomas, thyroid cancer, neuroblastoma, esophageal cancer, genitourinary tract cancer, malignant hypercalcemia, endometrial cancer, adrenal cortical cancer, neoplasms of the endocrine and exocrine pancreas, and prostate cancer.

[0068] The term "leukemia" refers broadly to progressive, malignant diseases of the blood- forming organs and is generally characterized by a distorted proliferation and development of leukocytes and their precursors in the blood and bone marrow. Leukemia is generally clinically classified on the basis of (1) the duration and character of the disease-acute or chronic; (2) the type of cell involved; myeloid (myelogenous), lymphoid (lymphogenous), or monocytic; and (3) the increase or non-increase in the number abnormal cells in the blood-leukemic or aleukemic

(subleukemic). Exemplary leukemias that may be treated with a compound or method provided herein include, for example, acute nonlymphocytic leukemia, chronic lymphocytic leukemia, acute granulocytic leukemia, chronic granulocytic leukemia, acute promyelocytic leukemia, adult

T-cell leukemia, aleukemic leukemia, a leukocythemic leukemia, basophylic leukemia, blast cell leukemia, bovine leukemia, chronic myelocytic leukemia, leukemia cutis, embryonal leukemia, eosinophilic leukemia, Gross' leukemia, hairy-cell leukemia, hemoblastic leukemia,

promyelocytic leukemia, Rieder cell leukemia, Schilling's leukemia, stem cell leukemia, subleukemic leukemia, or undifferentiated cell leukemia.

[0069] The term "lymphoma" refers broadly to a group of blood cell tumors that develop from cells of the immune system found in lymph, i.e. lymphocytes (e.g. natural killer cells (NK cells), T cells, and B cells). Lymphoma is typically classified into Hodgkin's lymphomas (HL) and the non-Hodgkin lymphomas (NHL) or based on whether it develops in B-lymphocytes (B-cells) or T-lymphocytes (T-cells). Exemplary lymphomas (Hodgkin's lymphomas and non- Hodgkin's lymphomas) that may be treated with a compound or method provided herein include, for example, nodular-sclerosis classical Hodgkin lymphoma, mixed cellularity classical Hodgkin lymphoma, lymphocyte-rich classical Hodgkin lymphoma, lymphocyte-depleted classical Hodgkin lymphoma, aggressive NHL, transformed NHL, indolent NHL, relapsed NHL, refractory NHL, low grade non-Hodgkin's Lymphoma, follicular lymphoma, large cell lymphoma, B-cell lymphoma, T-cell lymphoma, Mantle cell lymphoma, Burkitt's lymphoma, NK cell lymphoma, diffuse large B-cell lymphoma, and acute lymphoblastic lymphoma.

[0070] "Control" or "control experiment" is used in accordance with its plain ordinary meaning and refers to an experiment in which the subjects or reagents of the experiment are treated as in a parallel experiment except for omission of a procedure, reagent, or variable of the experiment. In some instances, the control is used as a standard of comparison in evaluating experimental effects. In some embodiments, a control is the measurement of the activity of a protein in the absence of a compound as described herein (including embodiments and examples). [0071] The terms "DNA" and "RNA" refer to deoxyribonucleic acid and ribonucleic acid, respectively.

[0072] Where a method disclosed herein refers to "amplifying" a nucleic acid, the term

"amplifying" refers to a process in which the nucleic acid is exposed to at least one round of extension, replication, or transcription in order to increase (e.g., exponentially increase) the number of copies (including complimentary copies) of the nucleic acid. The process can be iterative including multiple rounds of extension, replication, or transcription. Various nucleic acid amplification techniques are known in the art, such as PCR amplification or rolling circle amplification. [0073] A "primer" as used herein refers to a nucleic acid that is capable of hybridizing to a complimentary nucleic acid sequence in order to facilitate enzymatic extension, replication or transcription.

[0074] The words "complementary" or "complementarity" refer to the ability of a nucleic acid in a polynucleotide to form a base pair with another nucleic acid in a second polynucleotide. For example, the sequence 3'-A-G-T-C-5' is complementary to the sequence 3'-G-A-C-T-5' .

Complementarity may be partial, in which only some of the nucleic acids match according to base pairing, or complete, where all the nucleic acids match according to base pairing.

[0075] The terms "identical" or percent "identity," in the context of two or more nucleic acids, refer to two or more sequences or subsequences that are the same or have a specified percentage of nucleotides that are the same (i.e., about 60% identity, preferably 65%, 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or higher identity over a specified region, when compared and aligned for maximum correspondence over a comparison window or designated region) as measured using a BLAST or BLAST 2.0 sequence comparison algorithms with default parameters described below, or by manual alignment and visual inspection. See e.g., the NCBI web site at ncbi.nlm.nih.gov/BLAST. Such sequences are then said to be "substantially identical." This definition also refers to, or may be applied to, the compliment of a test sequence. The definition also includes sequences that have deletions and/or additions, as well as those that have substitutions. As described below, the preferred algorithms can account for gaps and the like. Preferably, identity exists over a region that is at least about 25 amino acids or nucleotides in length, or more preferably over a region that is 50-100 amino acids or nucleotides in length.

[0076] A variety of methods of specific DNA and RNA measurements that use nucleic acid hybridization techniques are known to those of skill in the art {see, Sambrook, Id.). Some methods involve electrophoretic separation {e.g., Southern blot for detecting DNA, and Northern blot for detecting RNA), but measurement of DNA and RNA can also be carried out in the absence of electrophoretic separation (e.g., quantitative PCR, dot blot, or array).

[0077] The sensitivity of the hybridization assays may be enhanced through use of a nucleic acid amplification system that multiplies the target nucleic acid being detected. Amplification can also be used for direct detection techniques. Examples of such systems include the polymerase chain reaction (PCR) system and the ligase chain reaction (LCR) system. Other methods include the nucleic acid sequence based amplification (NASBA, Cangene, Mississauga, Ontario) and Q Beta Replicase systems. These systems can be used to directly identify mutants where the PCR or LCR primers are designed to be extended or ligated only when a selected sequence is present. Alternatively, the selected sequences can be generally amplified using, for example, nonspecific PCR primers and the amplified target region later probed for a specific sequence indicative of a mutation. It is understood that various detection probes, including Taqman® and molecular beacon probes can be used to monitor amplification reaction products in real time. [0078] The terms "spliceosome" or "spliceosomal" are used according to their common and ordinary meaning and refer to the component or complex in a cell involved in removal of introns from transcribed pre-mRNA. A spliceosome may include a complex of small nuclear RNA (snRNA) and protein subunits.

[0079] The term "splicing" is used according to its common and ordinary meaning and refer to a process in a cell involved in removal of introns from transcribed pre-mRNA. During the splicing, the removal of introns and joining of exons from nascent pre-mRNA occur

simultaneously or sequentially. Splicing plays an important role in human biology and its relevance in developing and proliferation of cancer cells.

[0080] As defined herein, the term "inhibition", "inhibit", "inhibiting" and the like in reference to a protein-inhibitor interaction means negatively affecting (e.g., decreasing) the activity or function of the protein relative to the activity or function of the protein in the absence of the inhibitor. In some embodiments, inhibition refers to reduction of a disease or symptoms of disease. In some embodiments, inhibition refers to a reduction in the activity of a particular protein or nucleic acid target. In some embodiment, inhibition of the invention refers to an inhibition upon a splicing process in a cell, preferably in a cancer cell, using an inhibitor (e.g., antagonist, antibodies, RNAi molecules or small molecules). Thus, inhibition includes, at least in part, partially or totally blocking stimulation, decreasing, preventing, or delaying activation, or inactivating, desensitizing, or down-regulating signal transduction or enzymatic activity or the amount of a protein or protein complex (e.g. spliceosome). [0081] A "test compound" as used herein refers to an experimental compound as described herein that can be used in a screening process to identify activity, non-activity, or other modulation of a particularized biological target or pathway.

[0082] The term "modulation", "modulate", or "modulator" are used in accordance with their plain ordinary meaning and refer to the act of changing or varying one or more properties.

"Modulator" refers to a composition that increases or decreases the level of a target molecule or the function of a target molecule or the physical state of the target of the molecule. "Modulation" refers to the process of changing or varying one or more properties. For example, as applied to the effects of a modulator on a biological target, to modulate means to change by increasing or decreasing a property or function of the biological target or the amount of the biological target.

[0083] "Contacting" is used in accordance with its plain ordinary meaning and refers to the process of allowing at least two distinct species (e.g. chemical compounds including

biomolecules or cells) to become sufficiently proximal to react, interact or physically touch. It should be appreciated; however, the resulting reaction product can be produced directly from a reaction between the added reagents or from an intermediate from one or more of the added reagents which can be produced in the reaction mixture.

[0084] The term "contacting" may include allowing two species to react, interact, or physically touch, wherein the two species may be a compound as described herein and a protein or enzyme. In some embodiments contacting includes allowing a compound described herein to interact with a protein or enzyme that is involved in a signaling pathway.

[0085] As used herein, "biomolecule" is used in its customary sense and refers to a molecule found in nature or derivatives thereof, including macromolecules such as proteins, carbohydrates, lipids, and nucleic acids, as well as small molecules such as primary metabolites, secondary metabolites, and natural products. A biomolecule may be present as a moiety attached to the remainder of a compound. A biomolecule includes but is not limited to nucleic acids (e.g. DNA and RNA), peptide nucleic acids, sugars, peptides, proteins, antibodies, lipids, small molecule affinity ligands e.g. inhibitors, biotin and haptens.

[0086] As used herein, "carbohydrate" is used in its customary sense and refers to a molecule found in nature or derivatives thereof, which comprises carbon (C), hydrogen (H) and oxygen (O) atoms and typically containing polyhydroxy aldehydes, ketones, alcohols, acids, simple derivatives thereof and polymeric forms from monomeric units (monosaccharides). A

monosaccharide is used in its customary sense and refers to a basic building block of

carbohydrates or disaccharide containing two units of the monosaccharides. The monosaccharide can have either linear form or cyclic (ring) form and contains at least three carbons, at least four carbons, at least five carbons, or at least six carbons. The monosaccharide as used in the invention can have a 5 to 7 membered, or preferably, 6-membered ring structure. In addition, the monosaccharide may be chemically modified, for example, by removing or adding hydrogen, oxo, halogen, -OH, - H₂, -COOH, -CO H₂, substituted or unsubstituted alkyl (e.g., Ci-C₈, Ci- C₆, C₁-C4, or Ci-C₂), substituted or unsubstituted heteroalkyl (e.g., 2 to 8 membered, 2 to 6 membered, 4 to 6 membered, 2 to 3 membered, or 4 to 5 membered), substituted or unsubstituted cycloalkyl (e.g., C₃-C₈, C₃-C₆, C₄-C₆, or C₅-C₆), substituted or unsubstituted heterocycloalkyl (e.g., 3 to 8 membered, 3 to 6 membered, 4 to 6 membered, 4 to 5 membered, or 5 to 6 membered), substituted or unsubstituted aryl (e.g., C₆-Ci₂, C₆-Cio, or phenyl), or substituted or unsubstituted heteroaryl (e.g., 5 to 12 membered, 5 to 10 membered, 5 to 9 membered, or 5 to 6 membered).

[0087] "Pharmaceutically acceptable excipient" and "pharmaceutically acceptable carrier" refer to a substance that aids the administration of an active agent to and absorption by a subject and can be included in the compositions of the present invention without causing a significant adverse toxicological effect on the patient. Non-limiting examples of pharmaceutically acceptable excipients include water, NaCl, normal saline solutions, lactated Ringer's, normal sucrose, normal glucose, binders, fillers, disintegrants, lubricants, coatings, sweeteners, flavors, salt solutions (such as Ringer's solution), alcohols, oils, gelatins, carbohydrates such as lactose, amylose or starch, fatty acid esters, hydroxymethycellulose, polyvinyl pyrrolidine, and colors, and the like. Such preparations can be sterilized and, if desired, mixed with auxiliary agents such as lubricants, preservatives, stabilizers, wetting agents, emulsifiers, salts for influencing osmotic pressure, buffers, coloring, and/or aromatic substances and the like that do not deleteriously react with the compounds of the invention. One of skill in the art will recognize that other

pharmaceutical excipients are useful in the present invention. [0088] The term "preparation" is intended to include the formulation of the active compound with encapsulating material as a carrier providing a capsule in which the active component with or without other carriers, is surrounded by a carrier, which is thus in association with it.

Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid dosage forms suitable for oral administration. [0089] As used herein, the term "administering" means oral administration, administration as a suppository, topical contact, intravenous, parenteral, intraperitoneal, intramuscular, intralesional, intrathecal, intranasal or subcutaneous administration, or the implantation of a slow-release device, e.g., a mini-osmotic pump, to a subject. Administration is by any route, including parenteral and transmucosal (e.g., buccal, sublingual, palatal, gingival, nasal, vaginal, rectal, or transdermal). Parenteral administration includes, e.g., intravenous, intramuscular, intra-arteriole, intradermal, subcutaneous, intraperitoneal, intraventricular, and intracranial. Other modes of delivery include, but are not limited to, the use of liposomal formulations, intravenous infusion, transdermal patches, etc. [0090] By "co-administer" it is meant that a composition described herein is administered at the same time, just prior to, or just after the administration of one or more additional therapies. The compound of the invention can be administered alone or can be co-administered to the patient. Co-administration is meant to include simultaneous or sequential administration of the compound individually or in combination (more than one compound or agent). Thus, the preparations can also be combined, when desired, with other active substances (e.g. to reduce metabolic degradation).

[0091] The compositions disclosed herein can be delivered by transdermally, by a topical route, formulated as applicator sticks, solutions, suspensions, emulsions, gels, creams, ointments, pastes, jellies, paints, powders, and aerosols. Oral preparations include tablets, pills, powder, dragees, capsules, liquids, lozenges, cachets, gels, syrups, slurries, suspensions, etc., suitable for ingestion by the patient. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispersible granules. Liquid form preparations include solutions, suspensions, and emulsions, for example, water or water/propylene glycol solutions. The compositions of the present invention may additionally include components to provide sustained release and/or comfort. Such components include high molecular weight, anionic mucomimetic polymers, gelling polysaccharides and finely-divided drug carrier substrates. These components are discussed in greater detail in U.S. Pat. Nos. 4,911,920; 5,403,841; 5,212, 162; and 4,861,760. The entire contents of these patents are incorporated herein by reference in their entirety for all purposes. The compositions disclosed herein can also be delivered as microspheres for slow release in the body. For example, microspheres can be administered via intradermal injection of drug-containing microspheres, which slowly release subcutaneously (see Rao, J. Biomater Sci. Polym. Ed. 7:623-645, 1995; as biodegradable and injectable gel formulations (see, e.g., Gao Pharm. Res. 12:857-863, 1995); or, as microspheres for oral administration (see, e.g., Eyles, J. Pharm. Pharmacol. 49:669-674, 1997). In another embodiment, the formulations of the compositions of the present invention can be delivered by the use of liposomes which fuse with the cellular membrane or are endocytosed, i.e., by employing receptor ligands attached to the liposome, that bind to surface membrane protein receptors of the cell resulting in endocytosis.

By using liposomes, particularly where the liposome surface carries receptor ligands specific for target cells, or are otherwise preferentially directed to a specific organ, one can focus the delivery of the compositions of the present invention into the target cells in vivo. (See, e.g., Al- Muhammed, J Microencapsul. 13 :293-306, 1996; Chonn, Curr. Opin. Biotechnol. 6:698-708,

1995; Ostro, Am. J. Hosp. Pharm. 46: 1576-1587, 1989). The compositions can also be delivered as nanoparticles.

[0092] Pharmaceutical compositions may include compositions wherein the active ingredient (e.g. compounds described herein, including embodiments or examples) is contained in a therapeutically effective amount, i.e., in an amount effective to achieve its intended purpose. The actual amount effective for a particular application will depend, inter alia, on the condition being treated. When administered in methods to treat a disease, such compositions will contain an amount of active ingredient effective to achieve the desired result, e.g., modulating the activity of a target molecule, and/or reducing, eliminating, or slowing the progression of disease symptoms.

[0093] The dosage and frequency (single or multiple doses) administered to a mammal can vary depending upon a variety of factors, for example, whether the mammal suffers from another disease, and its route of administration; size, age, sex, health, body weight, body mass index, and diet of the recipient; nature and extent of symptoms of the disease being treated, kind of concurrent treatment, complications from the disease being treated or other health-related problems. Other therapeutic regimens or agents can be used in conjunction with the methods and compounds of Applicants' invention. Adjustment and manipulation of established dosages (e.g., frequency and duration) are well within the ability of those skilled in the art.

[0094] For any compound described herein, the therapeutically effective amount can be initially determined from cell culture assays. Target concentrations will be those concentrations of active compound(s) that are capable of achieving the methods described herein, as measured using the methods described herein or known in the art.

[0095] As is well known in the art, therapeutically effective amounts for use in humans can also be determined from animal models. For example, a dose for humans can be formulated to achieve a concentration that has been found to be effective in animals. The dosage in humans can be adjusted by monitoring compounds effectiveness and adjusting the dosage upwards or downwards, as described above. Adjusting the dose to achieve maximal efficacy in humans based on the methods described above and other methods is well within the capabilities of the ordinarily skilled artisan. [0096] Dosages may be varied depending upon the requirements of the patient and the compound being employed. The dose administered to a patient, in the context of the present invention should be sufficient to effect a beneficial therapeutic response in the patient over time. The size of the dose also will be determined by the existence, nature, and extent of any adverse side-effects. Determination of the proper dosage for a particular situation is within the skill of the practitioner. Generally, treatment is initiated with smaller dosages which are less than the optimum dose of the compound. Thereafter, the dosage is increased by small increments until the optimum effect under circumstances is reached. Dosage amounts and intervals can be adjusted individually to provide levels of the administered compound effective for the particular clinical indication being treated. This will provide a therapeutic regimen that is commensurate with the severity of the individual's disease state.

[0097] An "agonist," as used herein, refers to a compound capable of detectably increasing the expression or activity of a given protein or receptor. The agonist can increase expression or activity 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100% or more in comparison to a control in the absence of the agonist. In embodiments, expression or activity is 1.5-fold, 2-fold, 3-fold, 4-fold, 5-fold, 10-fold or more higher than the expression or activity in the absence of the agonist.

[0098] The term "antagonist" refers to a substance capable of detectably lowering expression or activity of a given protein. The antagonist can inhibit expression or activity 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100% or less in comparison to a control in the absence of the antagonist. In embodiments, the inhibition is 1.5-fold, 2-fold, 3-fold, 4-fold, 5-fold, 10-fold, or more than the expression or activity in the absence of the antagonist.

[0099] The term "nucleic acid" refers to deoxyribonucleotides or ribonucleotides and polymers thereof in either single-, double- or multiple-stranded form, or complements thereof. The term "polynucleotide" refers to a linear sequence of nucleotides. The term "nucleotide" typically refers to a single unit of a polynucleotide, i.e., a monomer. Nucleotides can be ribonucleotides, deoxyribonucleotides, or modified versions thereof. Examples of polynucleotides contemplated herein include single and double stranded DNA, single and double stranded RNA (including siRNA), and hybrid molecules having mixtures of single and double stranded DNA and RNA. Nucleic acids can be linear or branched. For example, nucleic acids can be a linear chain of nucleotides or the nucleic acids can be branched, e.g., such that the nucleic acids comprise one or more arms or branches of nucleotides. Optionally, the branched nucleic acids are repetitively branched to form higher ordered structures such as dendrimers and the like.

[0100] Nucleic acids, including nucleic acids with a phosphothioate backbone can include one or more reactive moieties. As used herein, the term reactive moiety includes any group capable of reacting with another molecule, e.g., a nucleic acid or polypeptide through covalent, non- covalent or other interactions. By way of example, the nucleic acid can include an amino acid reactive moiety that reacts with an amio acid on a protein or polypeptide through a covalent, non- covalent or other interaction. [0101] The terms also encompass nucleic acids containing known nucleotide analogs or modified backbone residues or linkages, which are synthetic, naturally occurring, and non- naturally occurring, which have similar binding properties as the reference nucleic acid, and which are metabolized in a manner similar to the reference nucleotides. Examples of such analogs include, without limitation, phosphodiester derivatives including, e.g., phosphoramidate, phosphorodiamidate, phosphorothioate (also known as phosphothioate), phosphorodithioate, phosphonocarboxylic acids, phosphonocarboxylates, phosphonoacetic acid, phosphonoformic acid, methyl phosphonate, boron phosphonate, or O-methylphosphoroamidite linkages (see

Eckstein, OLIGONUCLEOTIDES AND ANALOGUES: A PRACTICAL APPROACH, Oxford University Press); and peptide nucleic acid backbones and linkages. Other analog nucleic acids include those with positive backbones; non-ionic backbones, modified sugars, and non-ribose backbones (e.g. phosphorodiamidate morpholino oligos or locked nucleic acids (LNA)), including those described in U.S. Patent Nos. 5,235,033 and 5,034,506, and Chapters 6 and 7, ASC Symposium Series 580, Carbohydrate Modifications in Antisense Research, Sanghui & Cook, eds. Nucleic acids containing one or more carbocyclic sugars are also included within one definition of nucleic acids. Modifications of the ribose-phosphate backbone may be done for a variety of reasons, e.g., to increase the stability and half-life of such molecules in physiological

environments or as probes on a biochip. Mixtures of naturally occurring nucleic acids and analogs can be made; alternatively, mixtures of different nucleic acid analogs, and mixtures of naturally occurring nucleic acids and analogs may be made. In embodiments, the internucleotide linkages in DNA are phosphodiester, phosphodiester derivatives, or a combination of both.

[0102] A "labeled nucleic acid or oligonucleotide" is one that is bound, either covalently, through a linker or a chemical bond, or noncovalently, through ionic, van der Waals,

electrostatic, or hydrogen bonds to a label such that the presence of the nucleic acid may be detected by detecting the presence of the detectable label bound to the nucleic acid. Alternatively, a method using high affinity interactions may achieve the same results where one of a pair of binding partners binds to the other, e.g., biotin, streptavidin. In embodiments, the

phosphorothioate nucleic acid or phosphorothioate polymer includes a detectable label, as disclosed herein and generally known in the art. [0103] The word "expression" or "expressed" as used herein in reference to a gene means the transcriptional and/or translational product of that gene. The level of expression of a DNA molecule in a cell may be determined on the basis of either the amount of corresponding mRNA that is present within the cell or the amount of protein encoded by that DNA produced by the cell. The level of expression of non-coding nucleic acid molecules (e.g., siRNA) may be detected by standard PCR or Northern blot methods well known in the art. See, Sambrook et al., 1989 Molecular Cloning: A Laboratory Manual, 18.1-18.88.

[0104] The term "recombinant" when used with reference, e.g., to a cell, or nucleic acid, protein, or vector, indicates that the cell, nucleic acid, protein or vector, has been modified by the introduction of a heterologous nucleic acid or protein or the alteration of a native nucleic acid or protein, or that the cell is derived from a cell so modified. Thus, for example, recombinant cells express genes that are not found within the native (non-recombinant) form of the cell or express native genes that are otherwise abnormally expressed, under expressed or not expressed at all. Transgenic cells and plants are those that express a heterologous gene or coding sequence, typically as a result of recombinant methods.

[0105] The terms "a" or "an," as used in herein means one or more. In addition, the phrase "substituted with a[n]," as used herein, means the specified group may be substituted with one or more of any or all of the named substituents. For example, where a group, such as an alkyl or heteroaryl group, is "substituted with an unsubstituted Ci-C₂o alkyl, or unsubstituted 2 to 20 membered heteroalkyl," the group may contain one or more unsubstituted Ci-C₂₀ alkyls, and/or one or more unsubstituted 2 to 20 membered heteroalkyls.

[0106] Descriptions of compounds of the present invention are limited by principles of chemical bonding known to those skilled in the art. Accordingly, where a group may be substituted by one or more of a number of substituents, such substitutions are selected so as to comply with principles of chemical bonding and to give compounds which are not inherently unstable and/or would be known to one of ordinary skill in the art as likely to be unstable under ambient conditions, such as aqueous, neutral, and several known physiological conditions. For example, a heterocycloalkyl or heteroaryl is attached to the remainder of the molecule via a ring heteroatom in compliance with principles of chemical bonding known to those skilled in the art thereby avoiding inherently unstable compounds.

[0218] In embodiments, the compound is a compound described herein (e.g., in an aspect, embodiment, example, table, figure, scheme, appendix, or claim).

[0219] III. Pharmaceutical Compositions

[0220] Also provided herein are pharmaceutical formulations. In embodiments, the pharmaceutical formulation includes a compound (e.g. Formulae (I), (II), (IIA), (IIB), (IIA-1), (IIA-2), (IIB-1), (IIB-2), (III), (IIIA), (IIIB), (IIIA-1), (IIIA-2), (IIIB-1) and (IIIB-2)) described above (including all embodiments thereof) and a pharmaceutically acceptable excipient.

[0221] The pharmaceutical composition may contain a dosage of the compound in a therapeutically effective amount.

[0222] 1. Formulations [0223] The pharmaceutical composition may be prepared and administered in a wide variety of dosage formulations. Compounds described herein (e.g., having a structure of Formula (I), (II), (IIA), (IIB), (IIA-1), (IIA-2), (IIB-1), (IIB-2), (III), (IIIA), (IIIB), (IIIA-1), (IIIA-2), (IIIB-1), or (IIIB-2)) may be administered orally, rectally, or by injection (e.g. intravenously,

intramuscularly, intracutaneously, subcutaneously, intraduodenally, or intraperitoneally).

[0224] For preparing pharmaceutical compositions from compounds described herein (e.g., having a structure of Formula (I), (II), (IIA), (IIB), (IIA-1), (IIA-2), (IIB-1), (IIB-2), (III), (IIIA), (IIIB), (IIIA-1), (IIIA-2), (IIIB-1), or (IIIB-2)), pharmaceutically acceptable carriers can be either solid or liquid. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispersible granules. A solid carrier may be one or more substance that may also act as diluents, flavoring agents, binders, preservatives, tablet disintegrating agents, or an encapsulating material.

[0225] In powders, the carrier may be a finely divided solid in a mixture with the finely divided active component. In tablets, the active component may be mixed with the carrier having the necessary binding properties in suitable proportions and compacted in the shape and size desired.

[0226] The powders and tablets preferably contain from 5% to 70% of the active compound. Suitable carriers are magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, a low melting wax, cocoa butter, and the like. The term "preparation" is intended to include the formulation of the active compound with encapsulating material as a carrier providing a capsule in which the active component with or without other carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid dosage forms suitable for oral administration. [0227] For preparing suppositories, a low melting wax, such as a mixture of fatty acid glycerides or cocoa butter, is first melted and the active component is dispersed homogeneously therein, as by stirring. The molten homogeneous mixture is then poured into convenient sized molds, allowed to cool, and thereby to solidify.

[0228] Liquid form preparations include solutions, suspensions, and emulsions, for example, water or water/propylene glycol solutions. For parenteral injection, liquid preparations can be formulated in solution in aqueous polyethylene glycol solution.

[0229] Aqueous solutions suitable for oral use can be prepared by dissolving the active component in water and adding suitable colorants, flavors, stabilizers, and thickening agents as desired. Aqueous suspensions suitable for oral use can be made by dispersing the finely divided active component in water with viscous material, such as natural or synthetic gums, resins, methylcellulose, sodium carboxymethylcellulose, and other well-known suspending agents.

[0230] Also included are solid form preparations that are intended to be converted, shortly before use, to liquid form preparations for oral administration. Such liquid forms include solutions, suspensions, and emulsions. These preparations may contain, in addition to the active component, colorants, flavors, stabilizers, buffers, artificial and natural sweeteners, dispersants, thickeners, solubilizing agents, and the like.

[0231] The pharmaceutical preparation is preferably in unit dosage form. In such form the preparation is subdivided into unit doses containing appropriate quantities of the active component. The unit dosage form can be a packaged preparation, the package containing discrete quantities of preparation, such as packeted tablets, capsules, and powders in vials or ampoules. Also, the unit dosage form can be a capsule, tablet, cachet, or lozenge itself, or it can be the appropriate number of any of these in packaged form. [0232] The quantity of active component in a unit dose preparation may be varied or adjusted from 0.1 mg to 10000 mg according to the particular application and the potency of the active component. The composition can, if desired, also contain other compatible therapeutic agents.

[0233] Some compounds may have limited solubility in water and therefore may require a surfactant or other appropriate co-solvent in the composition. Such co-solvents include:

Polysorbate 20, 60, and 80; Pluronic F-68, F-84, and P-103; cyclodextrin; and polyoxyl 35 castor oil. Such co-solvents are typically employed at a level between about 0.01 % and about 2% by weight. Viscosity greater than that of simple aqueous solutions may be desirable to decrease variability in dispensing the formulations, to decrease physical separation of components of a suspension or emulsion of formulation, and/or otherwise to improve the formulation. Such viscosity building agents include, for example, polyvinyl alcohol, polyvinyl pyrrolidone, methyl cellulose, hydroxy propyl methylcellulose, hydroxyethyl cellulose, carboxymethyl cellulose, hydroxy propyl cellulose, chondroitin sulfate and salts thereof, hyaluronic acid and salts thereof, and combinations of the foregoing. Such agents are typically employed at a level between about 0.01% and about 2% by weight. [0234] The pharmaceutical compositions may additionally include components to provide sustained release and/or comfort. Such components include high molecular weight, anionic mucomimetic polymers, gelling polysaccharides, and finely-divided drug carrier substrates. These components are discussed in greater detail in U.S. Pat. Nos. 4,911,920; 5,403,841; 5,212,162; and 4,861,760. The entire contents of these patents are incorporated herein by reference in their entirety for all purposes.

[0235] The pharmaceutic composition may be intended for intravenous use. The

pharmaceutically acceptable excipient can include buffers to adjust the pH to a desirable range for intravenous use. Many buffers including salts of inorganic acids such as phosphate, borate, and sulfate are known.

[0236] 2. Effective Dosages

[0237] The pharmaceutical composition may include compositions wherein the active ingredient is contained in a therapeutically effective amount, i.e., in an amount effective to achieve its intended purpose. The actual amount effective for a particular application will depend, inter alia, on the condition being treated. For example, when administered in methods to treat leukemia (e.g., chronic lymphocytic leukemia), such compositions will contain amounts of active ingredients effective to achieve the desired result (e.g. increasing the extent of cancer cell death in the patient). [0238] The dosage and frequency (single or multiple doses) of compounds administered can vary depending upon a variety of factors, including route of administration; size, age, sex, health, body weight, body mass index, and diet of the recipient; nature and extent of symptoms of the disease being treated; presence of other diseases or other health-related problems; kind of concurrent treatment; and complications from any disease or treatment regimen. Other therapeutic regimens or agents can be used in conjunction with the methods and compounds disclosed herein.

[0239] Dosages may be varied depending upon the requirements of the subject and the compound being employed. The dose administered to a subject, in the context of the

pharmaceutical compositions presented herein, should be sufficient to effect a beneficial therapeutic response in the subject over time. The size of the dose also will be determined by the existence, nature, and extent of any adverse side effects. Generally, treatment is initiated with smaller dosages, which are less than the optimum dose of the compound. Thereafter, the dosage is increased by small increments until the optimum effect under circumstances is reached.

[0240] Dosage amounts and intervals can be adjusted individually to provide levels of the administered compounds effective for the particular clinical indication being treated. This will provide a therapeutic regimen that is commensurate with the severity of the individual's disease state. [0241] Utilizing the teachings provided herein, an effective prophylactic or therapeutic treatment regimen can be planned that does not cause substantial toxicity and yet is entirely effective to treat the clinical symptoms demonstrated by the particular patient. This planning should involve the careful choice of active compound by considering factors such as compound potency, relative bioavailability, patient body weight, presence and severity of adverse side effects, preferred mode of administration, and the toxicity profile of the selected agent.

[0242] 3. Toxicity

[0243] The ratio between toxicity and therapeutic effect for a particular compound is its therapeutic index and can be expressed as the ratio between LD₅₀ (the amount of compound lethal in 50% of the population) and ED₅₀ (the amount of compound effective in 50% of the population). Compounds that exhibit high therapeutic indices are preferred. Therapeutic index data obtained from cell culture assays and/or animal studies can be used in formulating a range of dosages for use in humans. The dosage of such compounds preferably lies within a range of plasma concentrations that include the ED₅₀ with little or no toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized. See, e.g. Fingl et al, In: THE PHARMACOLOGICAL BASIS OF THERAPEUTICS, Ch. l, p.l, 1975. The exact formulation, route of administration, and dosage can be chosen by the individual physician in view of the patient's condition and the particular method in which the compound is used. [0244] When parenteral application is needed or desired, particularly suitable admixtures for the compounds included in the pharmaceutical composition may be injectable, sterile solutions, oily or aqueous solutions, as well as suspensions, emulsions, or implants, including suppositories. In particular, carriers for parenteral administration include aqueous solutions of dextrose, saline, pure water, ethanol, glycerol, propylene glycol, peanut oil, sesame oil, polyoxyethylene-block polymers, and the like. Ampoules are convenient unit dosages. Pharmaceutical admixtures suitable for use in the pharmaceutical compositions presented herein may include those described, for example, in Pharmaceutical Sciences (19th Ed., Mack Pub. Co., Easton, PA) and WO 96/05309, the teachings of both of which are hereby incorporated by reference.

[0270] VI. Examples

[0271] Example 1 - A Carbohydrate-Derived Splice Modulator

[0272] Abstract Small molecule splice modulators have recently been recognized for their clinical potential for diverse cancers. This combined with their use as tools to study the importance of splice-regulated events and their association with disease continues to fuel the discovery of new splice modulators. One of the key challenges found in the current class of materials arises from their instability, where rapid metabolic degradation can lead to off-target responses. We now describe the preparation of bench-stable splice modulators by adapting carbohydrate motifs as a central scaffold to provide rapid access to potent splice modulators.

[0273] Introduction [0274] In 2007, two Japanese teams revealed the importance of targeting the SF3b unit of the spliceosome for anti -tumor therapy [1,2]. These breakthroughs not only forwarded the spliceosome as an important target for cancer [2], but also identified two key families of polyketide spliceosome modulators (FIG. 1), including FD-895 (la)[2], pladienolide B (lb)[3] and herboxidiene (lc) [4]. Since these discoveries, the development of splicing assays has been instrumental in the advance of next generation splice modulators. The success of these discoveries was further marked by the translation of an analog of pladienolide D, E7101, into phase I clinical trials[5]. However, many of these natural products are subject to low stability and/or poor pharmacological properties[6]. To this end, our laboratory has been a part of a growing medicinal chemistry effort to identify next generation splice modulators with improved pharmacological properties.

[0275] An attractive proposal suggested a method of analog development through the use of a consensus motif [7]. Pursuing this approach, their team has advanced the sudemycins [8] and a pladienolide-herboxidiene hybrid [9] as next generation leads. This, along with efforts at the Eisai Co. Ltd [10], H3 Biomedicine [11], Pfizer [12], Ghosh- Jurica laboratories [13], Koide laboratory [14], and our laboratories [15], have provided a strong foundation for achieving analogs with improved pharmacological properties. We now report on an advanced new class of splice modulators that are more potent, stable and rapidly accessible analogs.

[0276] In addition to carbohydrates being ubiquitous biological scaffolds, they are also derived from the natural chiral pool, making them ideal scaffolds for medicinal chemical optimization [16]. To expand on this hypothesis, we designed and prepared carbohydrate-derived compound, i.e. an analog of FD-895 whose core was derived from D-glucose.

[0277] Results

[0278] Our design began with FD-895 (la) due to the fact that earlier medicinal chemistry efforts in our laboratory provided derivatives with improved pharmacological properties [6a]. From these studies, we determined that manipulation of the stereochemistry at the C16-C19 diad (FIG. 1) provided an effective means to improve activity. From these data, we targeted a side chain that contained the exact terminus (FIG. 1), epoxide (FIG. 1), and diene groups (FIG. 1) as one of our more active analogs of FD-895 [6a]. Here, we incorporated already known SAR data to improve activity by selecting an improved C16-C19 stereodiad (shown in 2, FIG. 1).

[0279] Clues obtained from the solution structure analysis of FD-895 (la). While structural information on the eukaryotic spliceosome has recently been published [18], representation of the binding of a splice modulator with SF3b has yet to be established. We began by exploring the solution structure of the macrolide core of FD-895 (la). Using multiple solvents (CDC1₃ and C₆D₆) for data acquisition, we identified a series of NOE interactions that, along with coupling constant data, allowed assignment of the solution structure of the macrolide core (FIG. 2A). [0280] Design of a carbohydrate core motif. Using this structure and analyzing its spacefilling model, we began to search for motifs that accurately represented the macrolide core. Our goal was to find a structural unit that offered an improved synthetic entry and diverse means of tailoring, while also addressing previous pharmacological issues (stability and solubility). We began by inspecting the overlap between the small herboxidiene (lc) and large FD-895 (la) cores. While a clear overlay existed, it was evident that space occupied by the C4-C7 unit within la may not be a requirement for activity. We realized that simple monosaccharides such as D- glucose or D-galactose could provide a strong overlap with these cores. After evaluating several structures, we turned our attention to explore a-methyl-2,3,4-trimethoxy-D-glucopyranoside (3) as a core mimetic [19]. [0281] Structurally, glycoside 2 offered a functional map that lay between the core sizes of la and lc (FIGS. 2A-2E). As illustrated in FIGS. 2D-2E, the C2, C3, and C4 methoxy groups in 2 provided an improved fit to la relative to herboxadiene (FIGS. 2B-2C). Specifically, the C2 methoxy group of 2 filled the space taken by the C24 methyl group in la. Likewise, the C3 methoxy of 2 was able to partially fill the space of the C29-C30 acetate, a region that was already shown to tolerate functional modifications [20]. With this support, we turned our attention to the synthesis and biological evaluation analog 2.

[0282] Synthetic plan. Our plan focused on using a late-stage Julia-Kocienski olefination to couple a side chain derived from FD-895 to the monosaccharide core (see Scheme A). Here, we envisioned that we could leverage the extensive efforts from our own laboratory for development of pladienolide/FD-895 side chain [6a, 15b] as a means to probe the structure-activity

relationships (SARs) of side chain incorporating analogs. We therefore set out towards preparation of core component 8 (Scheme 1) and side chain component 16 (Scheme 2).

[0283] Synthesis of a carbohydrate core component 8. Synthesis of 8 was accomplished in 5 steps from 3, a monosaccharide derivative that in turn was prepared in 3 steps (54% yield) from a-methyl-D-glucopyranoside [19]. We began by oxidizing to aldehyde 4. Advantageously, we were able to reduce chromatographic purification efforts by using a combination of an IBX oxidation followed by solvent-dependent filtration through a pad of Si0₂. The addition of MeLi to crude 4 occurred with minimal by-product formation providing alcohol 5 in 82% yield from 3.

[0284] Repetition of the IBX oxidation procedure provided ketone 6, which could be rapidly purified by passage through a Si0₂ plug. While small samples of 6 were purified for

characterization, the crude product was readily subjected to a Horner-Wadsworth-Emmons olefination to afford ester 7. We were able to convert 5 to 7 in two steps and 80% yield with a single purification. Finally, ester 7 was reduced with DIBAL-H to afford core unit 8, which could be stored for months at -20 °C without decomposition. Overall, this process provides access to 8 in 66% in 5 steps from 3 (36% in 8 steps from a-methyl-D-glucopyranoside).

[0285] Synthesis of the side chain component 16. The synthesis of the side chain component began with allylic alcohol 9, an intermediate that was prepared at >10 g scale for the synthesis of FD-895 (la) [6a]. Allylic oxidation with Mn0₂ provided aldehyde 10, which was purified through a Si0₂ plug and directly submitted to a Crimmins aldol condensation with auxiliary 11, to afford adduct 12 in 87% yield over two steps. NMR analyses on the crude product indicated that this reaction occurred without detectable formation of other isomeric products.

[0286] With 12 in hand, the carbinol was protected as TBS ether 13, and the auxiliary was removed by NaBH₄ reduction. Optimization studies indicated that a 5 : 1 ratio of THF:CH₃OH provided a reproducibly high yield of 14. Completion of this component was accomplished by a two-step installation of the 1 -phenyl -lH-tetrazol- 5 -yl (PT) sulfone. While Mitsunobu conditions were effective at producing sulfone 15 in 82% yield at gram scales, oxidation often provided significant quantities of the corresponding sulfoxides (incomplete oxidation by-products).

Typically, samples of these sulfoxides were collected after chromatographic purification and resubmitted to the oxidation conditions to afford a combined yield of 89% of component 16. To date, we have completed the synthesis of gram quantities of 16 in 6 steps and 58% overall yield from 9 and 12 steps and 21% overall yield from auxiliary 11.

Scheme 3. Component assembly

[0287] Component assembly and completion of the synthesis of 2. With components 8 and 16 in hand, the component coupling began by oxidizing allylic alcohol 8 to the corresponding aldehyde 19. Purification via dry column vacuum chromatography using Geduran 60 silica gel was sufficient to afford pure 19 for coupling. After initial screening, we found the optimum yield (68%)) of 18 was obtained when applying 1.05 eq. NaHMDS to 1.0 eq. of sulfone 8 and following this by addition of 1.1 eq. of aldehyde 19. The yield of this reaction also included recovery of 8% of sulfone 16 and 11% of the chromatographically separable cz^'s-isomer of 18 (structure not shown). With samples of pure 18 at hand, deprotection with TBAF afforded alcohol 19.

[0288] Next, we turned to the stereoselective VO(acac)₂ catalyzed epoxidation of allylic alcohols²¹ to install the C12-C13 epoxide. As shown in FIG. 3A, treatment of 19 with 4.5 eq. of tBuOOH and 3 eq. of VO(acac)₂ at -20 °C for 6 h provided the desired stereoisomer with -4: 1 diastereoselectivity. While this was the major product, over warming or not starting the reaction at -78 °C resulted in epoxidation at C8-C9. This product was not stable as the CI 1 carbinol was capable of attacking the C8 center of the epoxide forming the corresponding furan analog (structure not shown). While additional optimization efforts will be required, the current conditions returned 2 in 52% yield with only traces of the undesired C8-C9 epoxidation (5-10% yield).

[0289] Validation of the structural assignment of 2. While the mechanism of the

VO(acac)₂/tBuOOH epoxidation suggests delivery of the correct stereochemical outcome, we wanted to gain further confirmation that the product was indeed 2. We began by exploring other epoxidation conditions to prepare samples of the other isomer. Treatment of 19 with 1.2 eq. of m- CPBA at -78 °C in NaHC0₃ buffered CH₂C1₂ followed by slow warming to room temperature afforded a -1 : 1 mixture of both epoxides (FIG. 3B) in 62% yield. After chromatographic purification, we were able to obtain samples of both isomers. [0290] Comparative NMR analyses on the epoxides from VO(acac)₂/tBuOOH and w-CPBA provided a solution (FIG. 3C). Using 2D NMR data set (see Supporting Information), we were able to fully assign the proton assignments in this product. First, we identified that the chemical shift and coupling patterns of the epoxide protons at C12-C13 provided the closest match to the configuration of the corresponding C16-C19 isomer le (FIG. 4), with comparable chemical shifts and coupling constants.

[0291] Stability and solubility of 2. Early studies indicate that 2 was more soluble and stable in aqueous buffers than FD-895 (la). Using capillary NMR and solvent ¹³C-satellites (QSCS) as a means of quantitation [22], we found that 2 was soluble up to 95±5 mM D₂0/DMSO-i¾ (10: 1) at 23 °C, while FD-895 (la) was limited to 15±5 mM under the same conditions. Additionally, we used NMR monitoring to show that while la had a half-life of -70 h in D₂0/DMSO-<f₆ (10: 1) at 37 °C [6a], carbohydrate-analog 2 showed no signs of decomposition even after 744 h (1 month) under the same conditions. While detailed partitioning, permeability, and metabolic stability analyses are ongoing, this initial evidence suggests that 2 offers the potential to improve pharmacological properties of this class of splice modulator. [0292] Epoxide 2 displays potent activity in primary CLL-B cells in contrast to its precursor alkene 19. We then screened the activity of 19 and 2 in primary CLL-B cells obtained from two CLL patients, that displayed potent in vitro cytotoxic activity (FIGS. 7A-7B) measured in form of specific induced apoptosis (% SIA) of la (IC₅₀ value of 54.1±7.5 nM) and lb (IC₅₀ value of 84.4±1.2 nM). Interestingly, these studies indicated that alkene 19 did not display any activity (IC₅₀ value >50 μΜ in both sets of cells). Epoxide 2, on the other hand, was active (IC₅₀ value of 153.0±11.8 nM) with ~3-fold loss of activity when compared to FD-895 (la).

[0293] Compound 2 modulates splicing. We then turned to RT-PCR analysis to determine if the activity of 2 also included a comparable splice response as la and lb in CLL-B cells. Using unspliced RNU6A and unmodulated GAPDH (top, FIG. 5) as controls, we were able to obtain complementary splice modulation in all six genes selected from our prior studies to provide a diversity of intron retention (IR) response.¹⁵³ This included comparable modification of IR in DNAJBI, ARF4, PRPF4, RIOK3, SF3A1, and U2AF2 (FIG. 4 and FIG. 8) from primary CLL-B cells. In contrast, alkene precursor 19 was inactive for all six genes (FIG. 5), indicating that the epoxide in 2 is essential for activity.

[0294] Additionally, we were able to confirm that compound 2 also induced alternate splicing (AS) events. As shown in FIG. 6, treatment of CLL-B cells with la, lb and 2 resulted in a decrease in the long (anti-apoptotic) form and increased the expression of short (pro-apoptotic) form oiMCLL Similarly, BCL-X demonstrates comparable AS events (FIG. 6). This indicates that cell death induced by la, lb and 2 is not exclusively derived through AS of MCL1 but may also include other players. This fact is further supported by RNAseq analyses [15a], which implicates the involvement of other pathways. Efforts are now underway to explore the roles of IR and AS events as well as to identify structural motifs that enrich specific events.

[0295] Experimental Section [0296] A. General experimental methods.

[0297] Chemical reagents were purchased from Acros, Fluka, Sigma-Aldrich, or TCI.

Deuterated MR solvents were purchased from Cambridge Isotope Laboratories. All reactions were conducted with rigorously dried anhydrous solvents that were obtained by passing through a solvent column composed of activated Al alumina. Anhydrous N,N-dimethylformamide was obtained by passage over activated molecular sieves and a subsequent NaOCN column to remove traces of dimethylamine. Triethylamine (Et₃N) was dried over Na and freshly distilled. Ethyl-

N,N-diisopropylamine (EtN/^'Pr₂) was distilled from ninhydrin, then from potassium hydroxide.

Anhydrous CH₃CN was obtained by distillation from CaH₂. All reactions were performed under positive pressure of Ar in oven-dried glassware sealed with septa, with stirring from a Teflon coated stir bars using an IKAMAG RCT-basic mechanical stirrer (IKA GmbH). Solutions were heated using either a sand or silicon oil bath. Analytical Thin Layer Chromatography (TLC) was performed on Silica Gel 60 F254 precoated glass plates (EM Sciences). Preparative TLC (pTLC) was conducted on Silica Gel 60 plates (EM Sciences). Visualization was achieved with UV light and/or an appropriate stain (I₂ on Si0₂, KMn0₄, bromocresol green, dinitrophenylhydrazine, ninhydrin, and eerie ammonium molybdate). Flash chromatography was carried out Geduran Silica Gel 60 (40-63 mesh) from EM Biosciences. Yields and characterization data correspond to isolated, chromatographically and spectroscopically homogeneous materials. ¹H MR spectra were recorded on Varian Mercury 300, Varian Mercury 400 spectrometers, Varian Mercury Plus 400, a JEOL ECA500, or a Varian VX500 spectrometer. A majority of the ¹³C MR spectra were recorded at 125 MHz on a Varian VX500 spectrometer equipped with an Xsens Cold probe. The remaining spectra were either collected at 125 MHz on a JEOL ECA 500, 100 MHz on a Varian Mercury 400 or 100 MHz on a Varian Mercury Plus 400 spectrometer. Chemical shifts for 1H NMR and ¹³C NMR analyses were referenced to the reported values of Gottlieb,¹ using the signal from the residual solvent for 1H spectra, or to the ¹³C signal from the deuterated solvent. Chemical shift δ values for 1H and ¹³C spectra are reported in parts per million (ppm) relative to these referenced values, and multiplicities are abbreviated as s = singlet, d = doublet, t = triplet, q = quartet, m = multiplet, br = broad. All ¹³C NMR spectra were recorded with complete proton decoupling. FID files were processed using MestraNova 6.0.2. (MestreLab Research).

Electrospray (ESI) mass spectrometric analyses were performed using a ThermoFinnigan LCQ Deca spectrometer, and high-resolution analyses were conducted using a ThermoFinnigan MAT900XL mass spectrometer with electron impact (EI) ionization. A Thermo Scientific LTQ Orbitrap XL mass spectrometer was used for high-resolution electrospray ionization mass spectrometry analysis (HR-ESI-MS). FTIR spectra were obtained on a Nicolet magna 550 series II spectrometer as thin films on either KBr or NaCl discs, and peaks are reported in wavenumbers (cm^"1). Optical rotations [a]_D were measured using a Perkin-Elmer Model 241 polarimeter with the specified solvent and concentration and are quoted in units of deg cm² g^"1. Spectral data were collected for all new compounds.

[0298] B. Synthesis of core chain component 8.

[0299] Component 8 was prepared in 8 steps in 36% overall yield from a-methyl-D- glucopyranoside (SI) as shown in Scheme 1 (above) and Scheme SI (below). Preparation of 6- trityl-a-methyl-a-D-glucopyranoside S2 was achieved by modification of methods developed by Crich, as described below. The following section provides a complete description of the synthetic procedures and spectroscopic properties of intermediated S2-S3, 3-8 and 19. [0300] Scheme SI depicts the synthesis of core component 8. Preparation of 8 required three chromatographic purifications as the crude products of S2, 3, 4, and 6 could be used without additional purification. Flash chromatography was required to purify intermediates S3, 5, and 7.

The final materials were stored. Aldehyde 19 was prepared immediately before the component coupling process as described in Scheme 3 and Scheme S3 following.

Blood samples were taken from two CLL patients after written informed consent for blood sample collection and confirmation of diagnosis for CLL diseases, The PBMCs were separated from heparinized venous blood by density gradient centrifugation using Ficoll-Hypaque media (GE Healthcare). The samples with >95% positivity for leukemic B cells was confirmed by staining for CD5 and CD 19 followed by assessment using flow cytometry. CLL-B cells were maintained in RPMI 1640 medium supplemented with 10% FBS, 2 mM L-glutamine, and 100 U/mL of penicillin and 100 μg/mL of streptomycin at 37 °C in an atmosphere containing 5% C0₂. [0339] In vitro cytotoxicity analyses. The CLL-B cells (3 x 10⁵ cells) were treated for 48 h with 10, 100, 300, and 1000 nM of la, lb, 2 or 19 at 37 °C in an atmosphere containing 5% C0₂. Fludarabine (F-ara-A) dosed at 10 μΜ was used as a control. The cells were centrifuged and labeled with CD19/CD5/DiOC6 and subjected to flow cytometry. The data was analyzed using FlowJo software. In order to discriminate the compound specific-induced apoptosis versus background spontaneous cell death from in vitro culture conditions, we calculated the percentage of specific induced apoptosis (% SIA) using the following formula: % SIA = [(compound induced apoptosis - media only spontaneous apoptosis) / (100 - media only spontaneous apoptosis)] x 100. The dose-response curves were plotted to determine IC₅₀ values using the GraphPad Prism version 6.0c software. [0340] Reverse transcriptase PCR (RT-PCR) analyses: CLL-B (5 10⁶ cells/well) were treated with a given dose of compound from a DMSO stock solution over 4 h. RNA isolation and cDNA preparation, PCR reaction was performed in 20

of reaction volume as described previously. PCR conditions give by incubation at 94 °C for 3 min; 35 cycles of 94 °C for 30 s, 55-60 °C (annealing temperature: 55 °C for GAPDH, 53.6 °C for RNU6A, 58 °C ior DNAJBl, 54 °C for SF3A1, 55 °C for PRPF4, 55 °C for ARF4, and 55 °C for U2AF2) for 30 s, and 72 °C for 1 min; followed by 72 °C for 5 min. PCR products were separated on a 2% agarose gel and stained with ethidium bromide. Details of the primers used for RT-PCR are provided in Table 1.

[0341] Quantitative reverse transcription-PCR (qRT-PCR): cDNA was prepared using identical methods as used for RT-PCR analysis. The amount of unspliced RNA for different genes was determined using Power SYBR Green PCR master mix (Applied Biosystems) by qRT-

PCR using specific primers designed for detection of the intron of each gene (Table 2). The qPCR was performed using 5 pM of each primer on 20 ng of the obtained cDNA. PCR conditions were as follows: one cycle of 50 °C for 2 min (UDG Incubation), one cycle of 95 °C for 10 min (UDG Inactivation), followed by 95 °C for 15 sec; 60 °C for 30 s for 40 cycles and adding a step for dissociation using a 7900 HT Fast Real Time PCR System (Applied

Biosystems). Unspliced RNA levels were calculated using 2-AACT method. GAPDH was used as a control for normalization.

Protons and carbons at 18 and 20 were assigned by H, C HMBC data. b Protons and carbons at 19 and 21 were assigned by 1H,¹³C HMBC data. However, they could not be unambiguously established due to the close proximity of C2 and C4. b The assignment of the protons and carbons at 25 was further confirmed by the fact that the chemical shifts of protons and carbons at 18, 19, 20 and 21 were comparable to that in precursors such as allylic alcohol 8.

Conclusion [0344] We describe herein the preparation of a carbohydrate-derived spliceosome inhibitor 2 in a total of 22 steps, including 12 longest linear steps from common building blocks (auxiliary 11, D-glucose and propionaldehyde). Complete in vitro and in vivo pharmacological analyses can be conducted, and this improved stability along with its improved solubility in aqueous buffers suggests an important advance in optimization of splice modulators.

[0345] Overall, this development offers several medicinal chemical benefits. First, it demonstrates that the pyran or macrolide core commonly associated with the known spliceosome inhibitors can be replaced with materials directly available from monosaccharides in the chiral pool. Second, it provides a means to prepare highly stable materials that lack rapid degradation and/or metabolic instability. Third, the use of a carbohydrate motif offers ready access to explore the SAR contained within the core unit (macrolide of la-lb or pyran in lc, FIG. 1). Here, one can envision application of the described route to provide derivatives with expanded functionality at the anomeric CI center, stereoisomers at C1-C4 positions, as well as explore the use of deoxygenated materials and alternative ethers at C1-C4. While to date there has been no structural information on the complex of any established splice modulator with the Sf3b component of the spliceosome, the subsequent integration of a rational design could deliver a carbohydrate-derived splice modulator with enhanced binding and reduced pharmacological risk.
