2. Description of Related Art
In eukaryotic cells, nuclear DNA associates with histones to form a compact complex called chromatin. The histones constitute a family of basic proteins which are generally highly conserved across eukaryotic species. The core histones, termed H2A, H2B, H3, and H4, associate to form a protein core. DNA winds around this protein core, with the basic amino acids of the histones interacting with the negatively charged phosphate groups of the DNA. Approximately 146 base pairs of DNA wrap around a histone core to make up a nucleosome particle, the repeating structural motif of chromatin.
Csordas, Biochem. J., 286: 23-38 (1990) teaches that histones are subject to posttranslational acetylation of the N-terminal lysine residues, a reaction that is catalyzed by histone acetyl transferase (HAT1). Acetylation neutralizes the positive charge of the lysine side chain, and is thought to impact chromatin structure. Indeed, Taunton et al., Science, 272: 408-411 (1996), teaches that access of transcription factors to chromatin templates is enhanced by histone hyperacetylation. Taunton et al. further teaches that an enrichment in underacetylated histone H4 has been found in transcriptionally silent regions of the genome.
Histone acetylation is a reversible modification, with deacetylation being catalyzed by a family of enzymes termed histone deacetylases (HDACs). The molecular cloning of gene sequences encoding proteins with HDAC activity has established the existence of a set of discrete HDAC enzyme isoforms. Grozinger et al., Proc. Natl. Acad. Sci. USA, 96:4868-4873 (1999), teaches that HDACs may be divided into two classes, the first represented by yeast Rpd3-like proteins, and the second represented by yeast Hd1-like proteins. Grozinger et al. also teaches that the human HDAC-1, HDAC-2, and HDAC-3 proteins are members of the first class of HDACs, and discloses new proteins, named HDAC-4, HDAC-5, and HDAC-6, which are members of the second class of HDACs. Kao et al., Gene & Development 14:55-66 (2000), discloses an additional member of this second class, called HDAC-7. More recently, Hu, E. et al. J. Bio. Chem. 275:15254-13264 (2000) disclosed another member of the first class of histone deacetylases, HDAC-8. Zhou et al., Proc. Natl. Acad. Sci. U.S.A., 98: 10572-10577 (2001) teaches the cloning and characterization of a new histone deacetylase, HDAC-9. Kao et al., J. Biol. Chem., 277:187-93 (2002) teaches the isolation and characterization of mammalian HDAC10, a novel histone deacetylase. Gao et al, J. Biol. Chem. (In press) teaches the cloning and functional characterization of HDAC11, a novel member of the human histone deacetylase family. Shore, Proc. Natl. Acad. Sci. U.S.A. 97: 14030-2 (2000) discloses another class of deacetylase activity, the Sir2 protein family. It has been unclear what roles these individual HDAC enzymes play.
Studies utilizing known HDAC inhibitors have established a link between acetylation and gene expression. Numerous studies have examined the relationship between HDAC and gene expression. Taunton et al., Science 272:408-411 (1996), discloses a human HDAC that is related to a yeast transcriptional regulator. Cress et al., J. Cell. Phys. 184:1-16 (2000), discloses that, in the context of human cancer, the role of HDAC is as a corepressor of transcription. Ng et al., TIBS 25: March (2000), discloses HDAC as a pervasive feature of transcriptional repressor systems. Magnaghi-Jaulin et al., Prog. Cell Cycle Res. 4:41-47 (2000), discloses HDAC as a transcriptional co-regulator important for cell cycle progression.
Richon et al., Proc. Natl. Acad. Sci. USA, 95: 3003-3007 (1998), discloses that HDAC activity is inhibited by trichostatin A (TSA), a natural product isolated from Streptomyces hygroscopicus, which has been shown to inhibit histone deacetylase activity and arrest cell cycle progression in cells in the G1 and G2 phases (Yoshida et al., J. Biol. Chem. 265: 17174-17179, 1990; Yoshida et al., Exp. Cell Res. 177: 122-131, 1988), and by a synthetic compound, suberoylanilide hydroxamic acid (SAHA). Yoshida and Beppu, Exper. Cell Res., 177: 122-131 (1988), teaches that TSA causes arrest of rat fibroblasts at the G1 and G2 phases of the cell cycle, implicating HDAC in cell cycle regulation. Indeed, Finnin et al., Nature, 401: 188-193 (1999), teaches that TSA and SAHA inhibit cell growth, induce terminal differentiation, and prevent the formation of tumors in mice. Suzuki et al., U.S. Pat. No. 6,174,905, EP 0847992 and JP 258863/96, disclose benzamide derivatives that induce cell differentiation and inhibit HDAC. Delorme et al., WO 01/38322 and WO 2001/070675, disclose additional compounds that serve as HDAC inhibitors. Other inhibitors of histone deacetylase activity, including trapoxin, depudecin, FR901228 (Fujisawa Pharmaceuticals), and butyrate, have been found to similarly inhibit cell cycle progression in cells (Taunton et al., Science 272: 408-411, 1996; Kijima et al., J. Biol. Chem. 268(30):22429-22435, 1993; Kwon et al., Proc. Natl. Acad. Sci. USA 95(7):3356-61, 1998).
Research in the past decade has uncovered a new classification of inherited neurodegenerative diseases, the polyglutamine (polyQ) expansion diseases. In each, the underlying mutation is an expansion of a CAG trinucleotide repeat that encodes polyQ in the respective disease protein. All are progressive, ultimately fatal disorders that typically begin in adulthood and progress over 10 to 30 years. The clinical features and pattern of neuronal degeneration differ among the diseases, yet increasing evidence suggests that polyQ diseases share important pathogenic features. In particular, abnormal protein conformations promoted by polyQ expansion seem to be central to pathogenesis. This class of PolyQ expansion neurodegenerative disease are Huntington's Disease (HD), Dentatorubralpallidoluysian atrophy (DRPLA), spinal and bulbar muscular atrophy (SBMA), and five spinocerebellar ataxias (SCA1, SCA2, SCA3/MJD (Machado-Joseph Disease), SCA6 and SCA7).
It is known that certain HDAC inhibitors, for example SAHA, CBHA and pryoxiamide can cross the blood brain barrier at sufficient amounts to significantly inhibit HDAC activity causing the accumulation of acetylated histones in the brain (WO 03/032921). This discovery therefore provides for the use of HDAC inhibitors for inhibiting HDAC in the brain, for the treatment of polyglutamine (polyQ) expansion diseases.
The art provides data that HDAC inhibitors are promising novel therapeutics for polyglutamine expansion diseases. Other data support a therapeutic benefit of HDAC inhibitors for Huntington's disease. Sadri-Vakili and Cha (Nature Clinical Practice Neurology, 2006, 2(6):330-338), and references cited therein, for example, review the current state of knowledge regarding the status of histones in Huntington's Disease and teach that recent studies have shown a therapeutic role for hisone deacetylase inhibitors in a number of Huntington's Disease models. In vivo, HDAC inhibitors arrest ongoing progressive neuronal degeneration induced by polygluatmine repeat expansion, and they reduce lethality in two Drosophila models of polyglutamine disease (Steffan et al., 2001, Nature 413: 739-743). Similar findings were observed with sodium butyrate and TSA (Zhao et al., 2005, J. Expt. Biol., 208:697-705). Gardian et al. (2005, J. Biol. Chem., 280:556-563) showed that phenylbutyrate is capable of improving survival and attenuating brain atrophy in the N171-82Q transgenic mouse model of Huntington's Disease. In the R6/2 model of Huntington's Disease, sodium butyrate extended survival, improved motor deficits and delayed neuropathological sequelae (Ferrante et al., 2003, J. Neurosci., 23:9418-9427). In that same model, suberoylanilide hydroxamic acid (SAHA) was also active in improving the motor impairment (Hockly, 2003, Proc. Natl. Acad. Sci. USA, 100:2041-0246). Ying et al. (2005, J. Biol. Chem., 281:12580-12586) showed that sodium butyrate improved life span and motor deficits in a mouse model for DRPLA. Bates et al. (2006, The Journal of Neuroscience, 26(10):2830-2838) reported that in Caenorhabditis elegans expressing a human huntingtin fragment with an expanded polyglutamine tract (Htn-Q150), knockdown of C. elegans hda-3 suppressed Htn-Q150 toxicity. Neuronal expression of hda-3 restored Htn-Q150 toxicity and suggested that C. elegans HDAC3 acts within neurons to promote degeneration in response to Htn-Q 150.
These findings suggest that inhibition of HDAC activity represents a novel approach for intervening in cell cycle regulation and that HDAC inhibitors have great therapeutic potential in the treatment of polyglutamine (polyQ) expansion diseases, such as Huntington's Disease. It would be highly desirable to have novel inhibitors of histone deacetylase.

In a preferred embodiment, the disease is Huntington's Disease.
In preferred embodiments, the individual is a mammal, preferably a primate, more preferably a human.
For purposes of the present invention, the following definitions will be used (unless expressly stated otherwise).
The terms “treating”, “treatment”, or the like, as used herein covers the treatment of a disease-state in an animal and includes at least one of: (i) preventing the disease-state from occurring, in particular, when such animal is predisposed to the disease-state but has not yet developed symptoms of having it; (ii) inhibiting the disease-state, i.e., partially or completely arresting its development; (iii) relieving the disease-state, i.e., causing regression of symptoms of the disease-state, or ameliorating a symptom of the disease; and (iv) reversal or regression of the disease-state, preferably eliminating or curing of the disease. In a preferred embodiment the terms “treating”, “treatment”, or the like, covers the treatment of a disease-state in an animal and includes at least one of (ii), (iii) and (iv) above. In a preferred embodiment of the present invention the animal is a mammal, preferably a primate, more preferably a human. As is known in the art, adjustments for systemic versus localized delivery, age, body weight, general health, sex, diet, time of administration, drug interaction and the severity of the condition may be necessary, and will be ascertainable with routine experimentation by one of ordinary skill in the art.
As used herein, the terms “histone deacetylase” and “HDAC” are intended to refer to any one of a family of enzymes that remove acetyl groups from a protein, such as for example, the e-amino groups of lysine residues at the N-terminus of a histone. Unless otherwise indicated by context, the term “histone” is meant to refer to any histone protein, including H1, H2A, H2B, H3, H4, and H5, from any species. Preferred histone deacetylases include class I and class II enzymes. Other preferred histone deacetylases include class III enzymes. Preferably the histone deacetylase is a human HDAC, including, but not limited to, HDAC-1, HDAC-2, HDAC-3, HDAC-4, HDAC-5, HDAC-6, HDAC-7, HDAC-8, HDAC-9, HDAC-10 and HDAC-11. In some other preferred embodiments, the histone deacetylase is derived from a protozoal or fungal source.
The terms “histone deacetylase inhibitor” and “inhibitor of histone deacetylase” are intended to mean a compound having a structure as defined herein, which is capable of interacting with a histone deacetylase and inhibiting its enzymatic activity.
The term “inhibiting histone deacetylase enzymatic activity” is intended to mean reducing the ability of a histone deacetylase to remove an acetyl group from a protein, such as a histone. The concentration of inhibitor which reduces the activity of a histone deacetylase to 50% of that of the uninhibited enzyme is determined as the IC50 value. In some preferred embodiments, such reduction of histone deacetylase activity is at least 50%, more preferably at least about 75%, and still more preferably at least about 905. In other preferred embodiments, histone deacetylase activity is reduced by at least 95% and more preferably by at least 99%.
Preferably, such inhibition is specific, i.e., the histone deacetylase inhibitor reduces the ability of a histone deacetylase to remove an acetyl group from a protein, such as a histone, at a concentration that is lower than the concentration of the inhibitor that is required to produce another, unrelated biological effect. Preferably, the concentration of the inhibitor required for histone deacetylase inhibitory activity is at least 2-fold lower, more preferably at least 5-fold lower, even more preferably at least 10-fold lower, and most preferably at least 20-fold lower than the concentration required to produce an unrelated biological effect.
For simplicity, chemical moieties are defined and referred to throughout primarily as univalent chemical moieties (e.g., alkyl, aryl, etc.). Nevertheless, such terms are also used to convey corresponding multivalent moieties under the appropriate structural circumstances clear to those skilled in the art. For example, while an “alkyl” moiety generally refers to a monovalent radical (e.g. CH3—CH2—), in certain circumstances a bivalent linking moiety can be “alkyl,” in which case those skilled in the art will understand the alkyl to be a divalent radical (e.g., —CH2—CH2—), which is equivalent to the term “alkylene.” (Similarly, in circumstances in which a divalent moiety is required and is stated as being “aryl,” those skilled in the art will understand that the term “aryl” refers to the corresponding divalent moiety, arylene). All atoms are understood to have their normal number of valences for bond formation (i.e., 4 for carbon, 3 for N, 2 for O, and 2, 4, or 6 for S, depending on the oxidation state of the S). On occasion a moiety may be defined, for example, as (A)a-B—, wherein a is 0 or 1. In such instances, when a is 0 the moiety is B— and when a is 1 the moiety is A-B—.
For simplicity, reference to a “Cn-Cm,” heterocyclyl or “Cn-Cm,” heteroaryl means a heterocyclyl or heteroaryl having from “n” to “m” annular atoms, where “n” and “m” are integers. Thus, for example, a C8-C6-heterocyclyl is a 5- or 6-membered ring having at least one heteroatom, and includes pyrrolidinyl (C5) and piperidinyl (C6); C6-heteroaryl includes, for example, pyridyl and pyrimidyl.

A “halohydrocarbyl” is a hydrocarbyl moiety in which from one to all hydrogens have been replaced with one or more halo.
The term “halogen” or “halo” is intended to mean chlorine, bromine, fluorine, or iodine. As herein employed, the term “acyl” refers to an alkylcarbonyl or arylcarbonyl substituent. The term “acylamino” refers to an amide group attached at the nitrogen atom (i.e., R—CO—NH—). The term “carbamoyl” refers to an amide group attached at the carbonyl carbon atom (i.e., NH2—CO—). The nitrogen atom of an acylamino or carbamoyl substituent is additionally optionally substituted. The term “sulfonamido” refers to a sulfonamide substituent attached by either the sulfur or the nitrogen atom. The term “amino” is meant to include NH2, alkylamino, arylamino, and cyclic amino groups. The term “ureido” as employed herein refers to a substituted or unsubstituted urea moiety.
The term “radical” is intended to mean a chemical moiety comprising one or more unpaired electrons.
Where optional substituents are chosen from “one or more” groups it is to be understood that this definition includes all substituents being chosen from one of the specified groups or the substituents being chosen from two or more of the specified groups.
In addition, substituents on cyclic moieties (i.e., cycloalkyl, heterocyclyl, aryl, heteroaryl) include 5-6 membered mono- and 9-14 membered bi-cyclic moieties fused to the parent cyclic moiety to form a bi- or tri-cyclic fused ring system.

An “unsubstituted” moiety (e.g., unsubstituted cycloalkyl, unsubstituted heteroaryl, etc.) means that moiety as defined above that does not have an optional substituent. Thus, for example, “unsubstituted aryl” does not include phenyl substituted with a halo.
The term “protecting group” is intended to mean a group used in synthesis to temporarily mask the characteristic chemistry of a functional group because it interferes with another reaction. A good protecting group should be easy to put on, easy to remove and in high yielding reactions, and inert to the conditions of the reaction required. A protecting group or protective group is introduced into a molecule by chemical modification of a functional group in order to obtain chemoselectivity in a subsequent chemical reaction. One skilled in the art will recognize that during any of the processes for preparation of the compounds in the present invention, it may be necessary and/or desirable to protect sensitive or reactive groups on any of the molecules concerned. This may be achieved by means of conventional protecting groups, such as but not limited to Bn— (or —CH2Ph), —CHPh2, alloc (or CH2═CH—CH2—O—C(O)—), BOC—, -Cbz (or Z—), —F-moc, —C(O)—CF3, N-Phthalimide, 1-Adoc-, TBDMS-, TBDPS-, TMS-, TIPS-, IPDMS-, —SiR3, SEM-, t-Bu-, Tr-, THP- and Allyl-. These protecting groups may be removed at a convenient stage using methods known from the art.
The term “therapeutically effective amount” as that term is used herein refers to an amount which elicits the desired therapeutic effect. The therapeutic effect is dependent upon the disease being treated and the results desired. As such, the therapeutic effect can be a decrease in the severity of symptoms associated with the disease and/or inhibition (partial or complete) of progression of the disease. Further, the therapeutic effect can be inhibition of HDAC in the brain. The amount needed to elicit the therapeutic response can be determined based on the age, health, size and sex of the patient. Optimal amounts can also be determined based on monitoring of the patient's response to treatment. Administration may be by any route, including, without limitation, parenteral, oral, sublingual, transdermal, topical, intranasal, intratracheal, or intrarectal. In certain particularly preferred embodiments, compounds of the invention are administered intravenously in a hospital setting. In certain other preferred embodiments, administration may preferably be by the oral route.

The invention also comprises all tautomeric forms of the compounds disclosed herein.
The present invention also includes prodrugs of compounds of the invention. The term “prodrug” is intended to represent covalently bonded carriers, which are capable of releasing the active ingredient when the prodrug is administered to a mammalian subject. Release of the active ingredient occurs in vivo. Prodrugs can be prepared by techniques known to one skilled in the art. These techniques generally modify appropriate functional groups in a given compound. These modified functional groups however regenerate original functional groups by routine manipulation or in vivo. Prodrugs of compounds of the invention include compounds wherein a hydroxy, amino, carboxylic, or a similar group is modified. Examples of prodrugs include, but are not limited to esters (e.g., acetate, formate, and benzoate derivatives), carbamates (e.g., N,N-dimethylaminocarbonyl) of hydroxy or amino functional groups in compounds of Formula (I)), amides (e.g., trifluoroacetylamino, acetylamino, and the like), and the like.
The compounds of the invention may be administered as is or as a prodrug, for example in the form of an in vivo hydrolyzable ester or in vivo hydrolyzable amide. An in vivo hydrolyzable ester of a compound of the invention containing carboxy or hydroxy group is, for example, a pharmaceutically acceptable ester which is hydrolyzed in the human or animal body to produce the parent acid or alcohol. Suitable pharmaceutically acceptable esters for carboxy include C1-6-alkoxymethyl esters (e.g., methoxymethyl), C1-6-alkanoyloxymethyl esters (e.g., for example pivaloyloxymethyl), phthalidyl esters, C3-8-cycloalkoxycarbonyloxyC1-6-alkyl esters (e.g., 1-cyclohexylcarbonyloxyethyl); 1,3-dioxolen-2-onylmethyl esters (e.g., 5-methyl-1,3-dioxolen-2-onylmethyl; and C1-6-alkoxycarbonyloxyethyl esters (e.g., 1-methoxycarbonyloxyethyl) and may be formed at any appropriate carboxy group in the compounds of this invention.
An in vivo hydrolyzable ester of a compound of the invention containing a hydroxy group includes inorganic esters such as phosphate esters and α-acyloxyalkyl ethers and related compounds which as a result of the in vivo hydrolysis of the ester breakdown to give the parent hydroxy group. Examples of α-acyloxyalkyl ethers include acetoxymethoxy and 2,2-dimethylpropionyloxy-methoxy. A selection of in vivo hydrolyzable ester forming groups for hydroxy include alkanoyl, benzoyl, phenylacetyl and substituted benzoyl and phenylacetyl, alkoxycarbonyl (to give alkyl carbonate esters), dialkylcarbamoyl and N—(N,N-dialkylaminoethyl)-N-alkylcarbamoyl (to give carbamates), N,N-dialkylaminoacetyl and carboxyacetyl. Examples of substituents on benzoyl include morpholino and piperazino linked from a ring nitrogen atom via a methylene group to the 3- or 4-position of the benzoyl ring. A suitable value for an in vivo hydrolyzable amide of a compound of the invention containing a carboxy group is, for example, a N—C1-6-alkyl or N,N-di-C1-6-alkyl amide such as N-methyl, N-ethyl, N-propyl, N,N-dimethyl, N-ethyl-N-methyl or N,N-diethyl amide.
For simplicity, and unless stated otherwise, a moiety is written in the direction corresponding to the order given in Formula (I). For example, if moiety J is —C0-6alkyl-aryl-C2-6heteroalkyl-, it is meant that the —C0-6alkyl-portion is attached to Q and the —C2-6heteroalkyl-portion is attached to L.

Compositions
In a second aspect, the invention provides compositions comprising an inhibitor of histone deacetylase according to the invention and a pharmaceutically acceptable carrier, excipient, or diluent. Compounds of the invention may be formulated by any method known in the art and may be prepared for administration by any route, including, without limitation, parenteral, oral, sublingual, transdermal, topical, intranasal, intratracheal, or intrarectal. In certain preferred embodiments, compounds of the invention are administered intravenously in a hospital setting. In certain other preferred embodiments, administration may preferably be by the oral route. The compositions may be in any form, including but not limited to, liquid solutions or suspensions; for oral administration, formulations may be in the form of tablets or capsules; and for intranasal formulations, in the form of powders, nasal drops or aerosols. The compositions of the invention may be administered systemically or locally.
The characteristics of the carrier will depend on the route of administration. As used herein, the term “pharmaceutically acceptable” means a non-toxic material that is compatible with a biological system such as a cell, cell culture, tissue, or organism, and that does not interfere with the effectiveness of the biological activity of the active ingredient(s). Thus, compositions according to the invention may contain, in addition to the inhibitor, diluents, fillers, salts, buffers, stabilizers, solubilizers, or other materials well known in the art. The preparation of pharmaceutically acceptable formulations is described in, e.g., Remington's Pharmaceutical Sciences, 18th Edition, ed. A. Gennaro, Mack Publishing Co., Easton, Pa., 1990.
As used herein, the term “pharmaceutically acceptable salts” is intended to mean salts that retain the desired biological activity of the above-identified compounds and exhibit minimal or no undesired toxicological effects. Examples of such salts include, but are not limited to acid addition salts formed with inorganic acids (for example, hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid, nitric acid, and the like), and salts formed with organic acids such as acetic acid, oxalic acid, tartaric acid, succinic acid, malic acid, ascorbic acid, benzoic acid, tannic acid, pamoic acid, alginic acid, polyglutamic acid, naphthalenesulfonic acid, naphthalenedisulfonic acid, and polygalacturonic acid. The compounds can also be administered as pharmaceutically acceptable quaternary salts known by those skilled in the art, which specifically include the quaternary ammonium salt of the formula —NR+Z—, wherein R is hydrogen, alkyl, or benzyl, and Z is a counterion, including chloride, bromide, iodide, —O-alkyl, toluenesulfonate, methylsulfonate, sulfonate, phosphate, or carboxylate (such as benzoate, succinate, acetate, glycolate, maleate, malate, citrate, tartrate, ascorbate, benzoate, cinnamoate, mandeloate, benzyloate, and diphenylacetate). As used herein, the term “salt” is also meant to encompass complexes, such as with an alkaline metal or an alkaline earth metal.
The active compound is included in the pharmaceutically acceptable carrier or diluent in an amount sufficient to deliver an inhibition effective amount without causing serious toxic effects. The effective dosage range of the pharmaceutically acceptable derivatives can be calculated based on the weight of the parent compound to be delivered. If the derivative exhibits activity in itself, the effective dosage can be estimated as above using the weight of the derivative, or by other means known to those skilled in the art.
In certain preferred embodiments of the second aspect of the invention, the composition further comprises an antisense oligonucleotide that inhibits the expression of a histone deacetylase gene. The combined use of a nucleic acid level inhibitor (e.g., antisense oligonucleotide) and a protein level inhibitor (i e, inhibitor of histone deacetylase enzyme activity) results in an improved inhibitory effect, thereby reducing the amounts of the inhibitors required to obtain a given inhibitory effect as compared to the amounts necessary when either is used individually. The antisense oligonucleotide according to this aspect of the invention is complementary to regions of RNA or double-stranded DNA that encode one or more of, for example, HDAC-1, HDAC-2, HDAC-3, HDAC-4, HDAC-5, HDAC-6, HDAC-7, HDAC-8, HDAC-9, HDAC-10 and HDAC-11 (see e.g., GenBank Accession Number U50079 for HDAC-1, GenBank Accession Number U31814 for HDAC-2, and GenBank Accession Number U75697 for HDAC-3).
Inhibition of Histone Deacetylase
In a third aspect, the present invention provides a method of inhibiting histone deacetylase, comprising contacting the histone deacetylase with an inhibition effective amount of an inhibitor of histone deacetylase of the present invention.
In another embodiment of the third aspect, the invention provides a method of inhibiting histone deacetylase in a cell, comprising contacting the cell in which inhibition of histone deacetylase is desired with an inhibition effective amount of an inhibitor of histone deacetylase, or composition thereof, according to the present invention.
Because compounds of the invention inhibit histone deacetylase, they are useful research tools for in vitro study histone deacetylases and their role in biological processes.
Measurement of the enzymatic activity of a histone deacetylase can be achieved using known methodologies. For Example, Yoshida et al., J. Biol. Chem., 265: 17174-17179 (1990), describes the assessment of histone deacetylase enzymatic activity by the detection of acetylated histones in trichostatin A treated cells. Taunton et al., Science, 272: 408-411 (1996), similarly describes methods to measure histone deacetylase enzymatic activity using endogenous and recombinant HDAC-1.
In some preferred embodiments, the histone deacetylase inhibitor interacts with and reduces the activity of all histone deacetylases in a cell. In some other preferred embodiments according to this aspect of the invention, the histone deacetylase inhibitor interacts with and reduces the activity of fewer than all histone deacetylases in the cell. In certain preferred embodiments, the inhibitor interacts with and reduces the activity of one histone deacetylase (e.g., HDAC-1), but does not interact with or reduce the activities of other histone deacetylases (e.g., HDAC-2, HDAC-3, HDAC-4, HDAC-5, HDAC-6, HDAC-7, HDAC-8, HDAC-9, HDAC-10 and HDAC-11).
The term “inhibition effective amount” is meant to denote a dosage sufficient to cause inhibition of histone deacetylase activity in a cell, which cell can be in a multicellular organism. The multicellular organism can be a plant or an animal, preferably a mammal, more preferably a human. If in a multicellular organism, the method according to this aspect of the invention comprises administering to the organism a compound or composition according to the present invention. Administration may be by any route, including, without limitation, parenteral, oral, sublingual, transdermal, topical, intranasal, intratracheal, or intrarectal. In certain particularly preferred embodiments, compounds of the invention are administered intravenously in a hospital setting. In certain other preferred embodiments, administration may preferably be by the oral route.
In certain preferred embodiments of the third aspect of the invention, the method further comprises contacting a histone deacetylase enzyme or a cell expressing histone deacetylase activity with an antisense oligonucleotide that inhibits the expression of a histone deacetylase gene. The combined use of a nucleic acid level inhibitor (e.g., antisense oligonucleotide) and a protein level inhibitor (i e, inhibitor of histone deacetylase enzyme activity) results in an improved inhibitory effect, thereby reducing the amounts of the inhibitors required to obtain a given inhibitory effect as compared to the amounts necessary when either is used individually. The antisense oligonucleotides according to this aspect of the invention are complementary to regions of RNA or double-stranded DNA that encode, for example, HDAC-1, HDAC-2, HDAC-3, HDAC-4, HDAC-5, HDAC-6, HDAC-7, HDAC-8, HDAC-9, HDAC-10 and HDAC-11 (see e.g., GenBank Accession Number U50079 for HDAC-1, GenBank Accession Number U31814 for HDAC-2, and GenBank Accession Number U75697 for HDAC-3).
For purposes of the invention, the term “oligonucleotide” includes polymers of two or more deoxyribonucleosides, ribonucleosides, or 2′-substituted ribonucleoside residues, or any combination thereof. Preferably, such oligonucleotides have from about 6 to about 100 nucleoside residues, more preferably from about 8 to about 50 nucleoside residues, and most preferably from about 12 to about 30 nucleoside residues. The nucleoside residues may be coupled to each other by any of the numerous known internucleoside linkages. Such internucleoside linkages include without limitation phosphorothioate, phosphorodithioate, alkylphosphonate, alkylphosphonothioate, phosphotriester, phosphoramidate, siloxane, carbonate, carboxymethylester, acetamidate, carbamate, thioether, bridged phosphoramidate, bridged methylene phosphonate, bridged phosphorothioate and sulfone internucleoside linkages. In certain preferred embodiments, these internucleoside linkages may be phosphodiester, phosphotriester, phosphorothioate, or phosphoramidate linkages, or combinations thereof. The term oligonucleotide also encompasses such polymers having chemically modified bases or sugars and/or having additional substituents, including without limitation lipophilic groups, intercalating agents, diamines and adamantane.
For purposes of the invention the term “2′-substituted ribonucleoside” includes ribonucleosides in which the hydroxyl group at the 2′ position of the pentose moiety is substituted to produce a 2′-O-substituted ribonucleoside. Preferably, such substitution is with a lower alkyl group containing 1-6 saturated or unsaturated carbon atoms, or with an aryl or allyl group having 2-6 carbon atoms, wherein such alkyl, aryl or allyl group may be unsubstituted or may be substituted, e.g., with halo, hydroxy, trifluoromethyl, cyano, nitro, acyl, acyloxy, alkoxy, carboxyl, carbalkoxyl, or amino groups. The term “2′-substituted ribonucleoside” also includes ribonucleosides in which the 2′-hydroxyl group is replaced with an amino group or with a halo group, preferably fluoro.
Particularly preferred antisense oligonucleotides utilized in this aspect of the invention include chimeric oligonucleotides and hybrid oligonucleotides.
For purposes of the invention, a “chimeric oligonucleotide” refers to an oligonucleotide having more than one type of internucleoside linkage. One preferred example of such a chimeric oligonucleotide is a chimeric oligonucleotide comprising a phosphorothioate, phosphodiester or phosphorodithioate region, preferably comprising from about 2 to about 12 nucleotides, and an alkylphosphonate or alkylphosphonothioate region (see e.g., Pederson et al. U.S. Pat. Nos. 5,635,377 and 5,366,878). Preferably, such chimeric oligonucleotides contain at least three consecutive internucleoside linkages selected from phosphodiester and phosphorothioate linkages, or combinations thereof.
For purposes of the invention, a “hybrid oligonucleotide” refers to an oligonucleotide having more than one type of nucleoside. One preferred example of such a hybrid oligonucleotide comprises a ribonucleotide or 2′-substituted ribonucleotide region, preferably comprising from about 2 to about 12 2′-substituted nucleotides, and a deoxyribonucleotide region. Preferably, such a hybrid oligonucleotide contains at least three consecutive deoxyribonucleosides and also contains ribonucleosides, 2′-substituted ribonucleosides, preferably 2′-O-substituted ribonucleosides, or combinations thereof (see e.g., Metelev and Agrawal, U.S. Pat. No. 5,652,355).
The exact nucleotide sequence and chemical structure of an antisense oligonucleotide utilized in the invention can be varied, so long as the oligonucleotide retains its ability to inhibit expression of the gene of interest. This is readily determined by testing whether the particular antisense oligonucleotide is active. Useful assays for this purpose include quantitating the mRNA encoding a product of the gene, a Western blotting analysis assay for the product of the gene, an activity assay for an enzymatically active gene product, or a soft agar growth assay, or a reporter gene construct assay, or an in vivo tumor growth assay, all of which are known in the art, or are as described in detail in this specification or in, for example, Ramchandani et al.

Antisense oligonucleotides utilized in the invention may conveniently be synthesized on a suitable solid support using well known chemical approaches, including H-phosphonate chemistry, phosphoramidite chemistry, or a combination of H-phosphonate chemistry and phosphoramidite chemistry (i.e., H-phosphonate chemistry for some cycles and phosphoramidite chemistry for other cycles). Suitable solid supports include any of the standard solid supports used for solid phase oligonucleotide synthesis, such as controlled-pore glass (CPG) (see, e.g., Pon, R. T. (1993) Methods in Molec.

No. 6,541,661, WO 01/70675, WO 2004/035525 and WO 2005/030705.
The following examples are intended to further illustrate certain preferred embodiments of the invention, and are not intended to limit the scope of the invention.
The following protocol is used to assay the compounds of the invention. In the assay, the buffer used is 25 mM HEPES, pH 8.0, 137 mM NaCl, 2.7 mM KCl, 1 mM MgCl2 and the substrate is Boc-Lys(Ac)-AMC in a 50 mM stock solution in DMSO. The enzyme stock solution is 4.08 μg/mL in buffer.
The compounds are pre-incubated (2 μl in DMSO diluted to 13 μl in buffer for transfer to assay plate) with enzyme (20 μl of 4.08 mg/ml) for 10 minutes at room temperature (35 μl pre-incubation volume). The mixture is pre-incubated for 5 minutes at room temperature. The reaction is started by bringing the temperature to 37° C. and adding 16 μl substrate. Total reaction volume is 50 μl. The reaction is stopped after 20 minutes by addition of 50 μl developer, prepared as directed by Biomol (Fluor-de-Lys developer, Cat. # KI-105). A plate is incubated in the dark for 10 minutes at room temperature before reading (λEx=360 nm, λEm=470 nm, Cutoff filter at 435 nm).
All compounds exemplified have an IC50 value less than or equal to 10 μM against one or more of HDAC-1, HDAC-2, HDAC-3, HDAC-4, HDAC-5, HDAC-6, HDAC-7, HDAC-8, HDAC-9, HDAC-10 and HDAC-11. Tables 8, 9 and 10 show selected examples. In the Tables 8, 9 and 10, A≦0.05 μM; 0.05 μM≦B≦0.1 μM; 0.1 μM<C≦1 μM; and 1 μM<D≦10 μM.
Primary neocortical cultures are established through the dissection of the neocortex from E17 embryos harvested from time-pregnant Balb/C mice. Following dissection, the neocortical tissue specimens undergo digestion by incubation at 37° C. for 10 minutes in dissection medium (1×HBSS/10 mM HEPES/1 mM Sodium Pyruvate) supplemented with (0.25%) Trypsin and (0.1%) DNase I. Digested tissue is washed and resuspended in plating medium (NeuroBasal/10% HS/0.5 mM L-Glutamine (Invitrogen Corporation)) for trituration. Additional plating medium is added, and the contents are passed over a 70 um cell-strainer. The cell-density is quantified using a hemacytometer, and dilutions are made to allow for the plating of 50000 cells/well/100 uL in 96-well PDL-coated plates. Plates are incubated for 4-5 hours in 37° C./5% CO2-incubator, after which time the entire volume is exchanged to feeding medium (NeuroBasal/2% B-27 Serum-free supplement/0.5 mM L-Glutamine/1% Penicillin-Streptomycin (Invitrogen Corporation)). The cultures undergo two 50% fresh feeding medium exchanges at 3 days in vitro (DIV3), and again at DIV7.
Compounds for testing are resuspended in dimethyl sulphoxide (DMSO), and further diluted in DMSO for a ten-point dose-response curve, with appropriate controls. Each master plate is assayed in triplicate. 3.5 uL/well of the master dilution plate is transferred to a 96-well round-bottom daughter plate, to which 175 uL/well of warmed feeding medium is added and thoroughly mixed. Three DIV9 culture plates are leveled to 50 uL/well, onto which each has overlaid 50 uL/well of the diluted daughter plate. The plates are returned to the 37° C./5% CO2-incubator for 16-18 hours.
The next step of the assay involves the exposure of a HDAC colorimetric substrate, comprising an acetylated lysine side chain, to the compound-treated neuronal cultures. Based on the ability of the compound to inhibit HDAC activity in the neuronal cultures, the substrate is deacetylated by HDACs, and subsequently sensitized. A 7.5 mM BOC-Lys(Ac)-AMC (Bachem Bioscience, Inc.) substrate solution is prepared by making a 1:1 dilution of 15 mM BOC-Lys(Ac)-AMC with HDAC Assay Buffer (25 mM Tris-Cl/137 mM NaCl/2.7 mM KCl/1 mM MgCl2). Compound-incubated culture plates are again leveled to 50 uL/well and 2 uL/well of 7.5 mM BOC-Lys (Ac)-AMC substrate is added and thoroughly mixed. Plates are returned to the 37° C./5% CO2-incubator for 1 hour.
The final addition to the culture plates entails treatment with a Fluor de Lys™-based developer (BIOMOL Research Laboratories, Inc.) to produce a fluorophore, which is analyzed using a spectrophotometer. The developer solution (1× Fluor de Lys™/1% NP-40/1 uM TSA in HDAC Buffer Solution) is prepared, and 50 uL/well is added to each of the wells of the culture plates. Trichostatin A is typically added as an “inhibitor stop” for class I and II HDACs. The plates are returned to the 37° C./5% CO2-incubator for 10-15 minutes, after which time, they are removed and set in the dark at room temperature for 5-10 minutes. The plates are read, and the results used to determine the percent HDAC activity of each compound compared to DMSO controls, and subsequently, used to calculate the corresponding IC50 values.
Pre-weighed liver and striatal specimens are transferred from −80° C. to wet-ice to be processed for tissue-homogenization. For the liver specimens, a 20-fold excess of chilled 1×XT LDS (Bio-Rad Laboratories, Inc.) sample buffer is added over the weight of each individual liver sample, and a 10-fold excess over the weight of the striatal samples. After adding 1.0 mm Zirconia-Silica beads (BioSpec Products, Inc.) to each sample, the tubes are loaded into the Mini-Beadbeater™ (BioSpec Products, Inc.), the liver samples are homogenized for 4 minutes, and the striatal samples for 3 minutes.
Rescued homogenates are then heated at 95° C. for 10-15 minutes, vortexed briefly, and centrifuged at 13200 rpm for 4 minutes. Samples are diluted 1:10, and 20×XT Reducing agent (Bio-Rad Laboratories, Inc.) is added in preparation for loading.
15 uL of each diluted sample is loaded in CRITERION™ 4-12% Bis-Tris gels (Bio-Rad Laboratories, Inc.) and run at 150V (constant) in a 1×XT MES buffer system (Bio-Rad Laboratories, Inc.) until the dye-front reaches the bottom.
Immobilon-FL PVDF-membranes (Millipore Corporation) are briefly activated in Methanol, hydrated in diH2O, and then equilibrated in chilled 1× Tris-Glycine transfer buffer (Bio-Rad Laboratories, Inc.) supplemented with 10% Methanol until the transfer-sandwiches are ready to be assembled. Gels are removed from the cartridges and equilibrated for 15 minutes in chilled transfer buffer. Transfer-sandwiches are assembled, loaded into the CRITERION™ Blotter System, and transferred for 40 minutes at 100V (constant).
PVDF-membranes are removed, rinsed briefly in diH2O, and then blocked for 1 hour in 1:1 dilution (in PBS) of Odyssey Blocking Buffer solution (LI-COR Bioscience, Inc.).
Primary antibody solution is prepared as follows: Into 40 mL of 1:1 diluted Odyssey Blocking Buffer is added 4 uL of anti-Actin (AC-15) antibody (Sigma-Aldrich Co.), 8 uL of anti-Acetylated H2A antibody (Millipore Corporation) and 20 uL of anti-Acetylated H4 antibody (Millipore Corporation). PVDF membranes are incubated in primary antibody solution overnight at 4° C.
Membranes are washed 4×5 minutes in TBS-T (Sigma-Aldrich Co.). Secondary antibody solution is prepared as follows: Into 40 mL of TBS-T solution, supplemented with 0.02% SDS (Sigma-Aldrich Co.), is added 4 uL of goat anti-rabbit IRDye800 antibody (Rockland, Inc.) and 4 uL of goat anti-mouse AlexaFluor 680 antibody (Invitrogen Corporation). PVDF membranes are incubated in secondary antibody solution, protected from light, for 1 h at room temperature. Membranes are washed 4×5 minutes in TBS-T, followed by 2×2 minute washes in PBS solution.
PVDF membranes are scanned using LI-COR/Odyssey Infrared Imaging System. Induced acetylation of Histone 2A or Histone 4 is calculated for each sample by dividing the integrated intensity of the designated acetylated histone band by the integrated intensity of the actin band from the same sample, correcting for loading variability. The individually normalized sample values from each treatment group, assayed in triplicate, are then averaged and plotted as a relative Histone 2A or Histone 4 acetylation level.
Normal human astrocyte cultures (Lonza, Inc.) are passaged using standard passaging techniques. Pelleted cells are resuspended in Astrocyte Growth Medium (Astrocyte Basal Medium/3% FBS/1% L-Glutamine/0.1% Ascorbic acid/0.1% rhEGF/0.25% Insulin/0.1% Gentamycin Sulfate-Amphotericin; (Lonza, Inc.)). The cell density is quantified using a hemacytometer, and dilutions are made to allow for the plating of 10000 cells/well/100 uL into 96-well flat-bottomed TC-treated plates. The cultures plates are incubated at 37° C./5% CO2 overnight.
Compounds for testing are resuspended in dimethyl sulphoxide (DMSO), and further diluted in DMSO for a ten-point dose-response curve, with appropriate controls. Each master plate is assayed in triplicate. 3.5 uL/well of the master dilution plate is transferred to a 96-well round-bottom daughter plate, to which 175 uL/well of warmed Astrocyte Growth Medium is added and thoroughly mixed. Three culture plates are leveled to 50 uL/well, onto which each has overlaid 50 uL/well of the diluted daughter plate. The plates are returned to the 37° C./5% CO2-incubator for 16-18 hours.
The next step of the assay involves the exposure of a HDAC colorimetric substrate, comprising an acetylated lysine side chain, to the compound-treated human astrocyte cultures. Based on the ability of the compound to inhibit HDAC activity in the human astrocyte cultures, the substrate is deacetylated by HDACs, and subsequently sensitized. A 7.5 mM BOC-Lys(Ac)-AMC (Bachem Bioscience, Inc.) substrate solution is prepared by making a 1:1 dilution of 15 mM BOC-Lys(Ac)-AMC with HDAC Assay Buffer (25 mM Tris-Cl/137 mM NaCl/2.7 mM KCl/1 mM MgCl2). Compound-incubated culture plates are again leveled to 50 uL/well and 2 uL/well of 7.5 mM BOC-Lys (Ac)-AMC substrate is added and thoroughly mixed. Plates are returned to the 37° C./5% CO2-incubator for 1 hour.
The final addition to the culture plates entails treatment with a Fluor de Lys™-based developer (BIOMOL Research Laboratories, Inc.) to produce a fluorophore, which is analyzed using a spectrophotometer. The developer solution (1× Fluor de Lys™/1% NP-40/1 uM TSA in HDAC Buffer Solution) is prepared, and 50 uL/well is added to each of the wells of the culture plates. Trichostatin A is typically added as an “inhibitor stop” for class I and II HDACs. The plates are returned to the 37° C./5% CO2-incubator for 10-15 minutes, after which time, they are removed and set in the dark at room temperature for 5-10 minutes. The plates are read, and the results are used to determine the percent HDAC activity of each compound compared to DMSO controls, and subsequently, used to calculate the corresponding IC50 values.
The activity (IC50 μM) of selected compounds in the above-mentioned neuronal cell based assay are shown in Tables 8, 9 and 10. In the Tables 8, 9 and 10, W≦1 μM; 1<X≦5 μM; 5<Y≦15 μM; and 15<Z.
The present invention discloses methods and pharmaceutical compositions for treating polyglutamine (polyQ) expansion diseases. In certain preferred embodiments, the disease is selected from the group consisting of Huntington's Disease (HD), Dentatorubralpallidoluysian atrophy (DRPLA), spinal and bulbar muscular atrophy (SBMA), and five spinocerebellar ataxias (SCA1, SCA2, SCA3/MJD (Machado-Joseph Disease), SCA6 and SCA7).
The suitability of a compound for treatment of a polyglutamine (polyQ) expansion diseases can be assessed in any of a number of animal models. For example, mice transgenic for an expanded polyglutamine repeat mutant of ataxin-1 develop ataxia typical of spinocerebellar ataxia type 1 (SCA-I) are known (Burright et al., 1995, Cell 82: 937-948; Lorenzetti et al., 2000, Hum. MoI. Genet. 9: 779-785; Watase, 2002, Neuron 34: 905-919), and can be used to determine the efficacy of a given compound in the treatment or prevention of neurodegenerative disease. Additional animal models, for example, for Huntington's disease (see, e.g., Mangiarini et al., 1996, Cell 87: 493-506, Lin et al., 2001, Hum. MoI. Genet. 10: 137-144), can be used to evaluate the efficacy of the compounds of the present invention in a similar manner.
Animal models are not limited to mammalian models. For example, Drosophila strains provide accepted models for a number of neurodegenerative disorders.
The Drosophila Huntington's Disease assay used to screen compounds of the present invention followed that of WO 2007/002497, which is hereby incorporated by reference in its entirety.
Drosohila melanogaster Fly Production:
Briefly, parental (model and driver) lines are maintained in sufficient quantities to provide virgins and males for assay crosses as well as perpetuating the lines. Disease model flies are maintained with the disease genes “silent”, functionally linked to a UAS enhancer element. The “driver” lines contain a GAL4 element under the control of a tissue-specific promoter. These are crossed together to generate the assay flies which have tissue-specific (i.e. CNS) expression of the disease gene(s).
Weekly assay crosses are set up with sufficient virgins and males to generate enough assay embryos for sorting. Approximately 50,000 males and 75,000 virgins are crossed in population cages. Embryos are collected for an eight hour window two days later. The embryos are then sorted onto 16 mm assay vials containing regular fly media and allowed to develop. Flies containing both the GAL4 driver element and the disease gene(s) are detected by the presence of GFP, a fluorescing protein. Approximately 10 assay flies eclose per vial, the optimal number for the behavioral assay. Once the flies eclose, they are transferred onto assay vials containing liquid Drosophila food. Similarly, control crosses are set up with virgins of the driver and males from a non-disease UAS line. Throughout fly production and the assay days, all flies are maintained at constant temperature and humidity, with preset light cycle, optimized for the particular lines and crosses.
Quality control (QC) for the parental lines is carried out weekly by collecting a sample of random male flies from each line. Single-fly PCR is carried out to ascertain the presence of the GAL4 or UAS element. If greater than 5% of the individuals lack the appropriate element, the assay cross is aborted. A second form of QC is also carried out to ensure that the GAL4 element is able to drive expression of a transgene. A sample of individual “driver” virgins is crossed to UAS-GFP males. Their progeny are visually checked for GFP expression in the appropriate tissues. Lack of GFP in greater than 4% of the crosses results in the assay being aborted.
Compound Handling and Dosing:
Test compounds are weighed out and dissolved in DMSO at stock concentrations 100× what is desired in the assay and arrayed into 96-well master plates, including wells for DMSO-only controls and the positive control(s). A single well is reserved for a colored dye used to ensure proper orientation of compounds during drug dispensing and fly transfer. Replicate daughter plates for each day of the assay are stamped out. The plates are bar coded and stored at −20 C until used for the assay.
For a particular assay day, the plates are thawed and a robotic liquid handler is used to dilute the test compound into the liquid fly food and dispense the mixture into the assay vials. For Huntington Disease (HD) models, eight replicates per single treatment (one compound, one concentration) are dispensed. Fresh test compound treated media is made daily during an assay.
Automated Behavioral Assay:
On the day the assay flies eclose (emerge from larvae; assay Day 0) they are transferred to the test compound treated vials. On assay Day 1, the flies are transferred onto clean test compound treated vials one hour before assay time. They are then placed in the assay machine to acclimate to the appropriate climate conditions.
The assay machine is an environmentally-enclosed and controlled robot that can maintain user-set temperature and humidity. The machine can hold up to sixteen 96-vial racks in four quadrants, for a total of 1536 vials. There are four camera stations, which hold four vials each and a CCD camera for movie capture. A robotic arm carries a gripper which picks up four vials at a time, places them in a designated camera station, taps the vials to stimulate fly climbing behavior, then moves onto the next rack to pick up four vials into the next camera station, etc. For HD assays, each vial is recorded four times for 7.5 seconds, the recording starting after the vials are tapped.
After the assay run, the racks of flies are returned to the warm rooms at the designated temperature and humidity. This process is repeated for all days of the assay (10 for HD assays).
The movies are then “tracked”; using a number of parameters given in the TrackingServer custom application, movement of the flies in each movie is converted into a tracking file. Each tracking file is then processed by the scoring server, converting the movement of the flies into a number of measurements for each movie for each individual vial for a particular trial day. The measurements for each movie are outputted as a .CSV file.
Analysis and Hit Determination:
Examples of metrics are included below:
The particular spectrum of metrics to detect improvement in behavior of a treated disease fly vs. an untreated disease fly differs from disease model to disease model. Metrics are chosen based on the dynamic range of i) the difference between untreated disease and positive control and ii) the difference between untreated disease and non-disease. For the Huntington's disease screening model, speed is the best metric. Summary metrics for performance are used to determine effect sizes of treatments vs. control. The summary metrics used for the HD model are “early speed”, the average speed for days 1-7 and “late speed”, the average speed for days 8-10. These day ranges were chosen based on the shape of the speed curves and the t-statistic for all different day ranges. Toxicity for a compound treatment is determined by fly loss throughout the assay.
The effect sizes for the performance metrics are calculated for the different treatments by dividing the value for the metric by the pooled standard deviation for the assay. Certain systematic variations in the data can be modeled and integrated into the analysis. For example, a linear statistical model for rack position or drug dispense order can be applied to correct the effect sizes. A final assessment of assay and data quality is done by the experimenters.
For test compound treatments, a multiple repeat strategy is used to define compound hits. Statistical power is set to decrease the number of false positives and to increase the number of true positives. A threshold of effect size is set for each of three assays per treatment. A treatment below threshold for the first or second pass is not run in a third pass without convincing rationale. For current screening with the HD model, the effect size threshold for a hit after three passes is >0.4 early speed (effect size) or >0.6 late speed (effect size). Strong hits are defined are effect sizes of >0.8 early speed and >1.2 late speed. Effect size is defined as the difference between DMSO-carrier control and test compound divided by the pooled standard deviation in the whole assay (preferred test compounds have early effect size>0.4 or late effect size>0.6; more preferred test compounds have early effect size>0.6 or late effect size>1.2). TSA was used as a HDAC positive control.
Compounds according to the present invention are able to cross the blood brain barrier in treated mice and inhibit a histone deacetylase in a cell thereacross, thereby increasing histone acetylation in the brain.
