BACKGROUND OF THE INVENTION
Huntington's disease (HD) is an autosomal dominant inherited neurodegenerative disorder that is characterized by progressive motor dysfunction, emotional disturbances, dementia, and weight loss. There currently is no treatment for delaying the onset of the disease or for slowing the progression of HD. Management of HD is focused on symptom reduction, and the only drug approved by the FDA is tetrabenazine, which is indicated to suppress involuntary movements (chorea) but does not slow the disease progression. The disease is caused by an elongated CAG trinucleotide repeat expansion located within exon 1 of the IT-15 gene encoding huntingtin, a 350-kDa protein of unknown function. The CAG repeat is translated into a polyglutamine (polyQ) stretch. In HD patients, huntingtin is expressed with 38-180 glutamine residues, whereas in healthy individuals the protein is synthesized with 8-37 glutamine residues. The accumulation of ubiquitinated polyQ-containing huntingtin aggregates in neuronal inclusions causes the death of affected neurons and has emerged as a pathologic hallmark of HD. Inhibiting polyQ aggregation has exhibited some efficacy in vivo in both Drosophila and mouse models of HD, which suggests that inhibition of neuronal polyQ aggregation might be therapeutic in HD patients.
Sirtuins comprise a family of protein deacetylase enzymes that have been shown to impact longevity in a number of eukaryotic species. The role for sirtuins as therapeutic targets in age-dependent neurodegenerative disorders has recently emerged, primarily as a result of their functions as regulators of metabolism and subsequent effects on longevity. SIRT2, one of the seven human sirtuins so far identified, belongs to the class III histone deacetylases (HDAC), which couple hydrolysis of acetyllysine residues with NAD hydrolysis. Known substrates of SIRT2 include α-tubulin, FOXO1, FOXO3a, P523, and histones 3 and 4. (See, e.g., Taylor, D. M.; Maxwell, M. M.; Luthi-Carter, R.; Kazantsev, A. G. Biological and potential therapeutic roles of sirtuin deacetylases. Cell Mol. Life Sci. 2008, 65, 24, 4000 4018; and North, B. J.; Marshall, B. L.; Borra, M. T.; Denu, J. M.; Verdin, E. The human Sir2 ortholog, SIRT2, is an NAD+-dependent tubulin deacetylase. Mol. Cell 2003, 11, 2, 437 444.) SIRT2 level is sharply increased during neurodevelopment, remains strikingly high in mature brain, and accumulates in the aged CNS. Chemical inhibition of SIRT2 changes protein inclusion body characteristics and increases neuronal survival in animal models of Parkinson's disease. It also achieves neuroprotection in cellular and invertebrate models of HD and leads to increased acetylation of its substrate α-tubulin, a major component of microtubules, subsequently leading to neuroprotective transcriptional modulation of metabolic pathways and to reduction of polyQ inclusions in HD primary neurons by decreasing sterol biosynthesis.
Cell-based high-throughput and in silico screening identified small-molecule sulfobenzoic acid derived inhibitors of polyQ aggregation and SIRT2 (FIG. 1). C2-8 inhibited polyQ aggregation in brain slices from R6/2 HD transgenic mice at sub-micromolar concentrations, reversed the effects of neurodegeneration in a fruit fly model of HD, crossed the blood brain barrier following oral administration, inhibited huntingtin (htt) aggregation in vivo in the striatum by 25-30% in R6/2 mice, effectively suppressed aggregation in a cell-based model with an EC50=50 nM, significantly reduced striatal neuron loss in R6/2 mice and improved their clinical phenotype, markedly reduced htt aggregation by 50% in the 140 CAG knock-in model of HD, which is much more analogous to human HD, and was not toxic in acute and chronic tolerability studies. (See, e.g., Chopra, V.; Fox, J. H.; Lieberman, G.; Dorsey, K.; Matson, W.; Waldmeier, P.; Housman, D. E.; Kazantsev, A.; Young, A. B.; Hersch, S. A small-molecule therapeutic lead for Huntington's disease: preclinical pharmacology and efficacy of C2-8 in the R6/2 transgenic mouse. Proc. Natl. Acad. Sci. USA 2007, 104, 42, 16685-16689.) AK-1 was neuroprotective in C. elegans and Drosophila HD models and inhibited polyQ aggregation in primary rat striatal neurons expressing the mutant huntingtin fragment delivered by a lentivirus and selectively inhibited SIRT2 at low micromolar concentrations (IC50=12.5 μM). (See, e.g., Taylor, D. M.; Balabadra, U.; Xiang, Z.; Woodman, B.; Meade, S.; Amore, A.; Maxwell, M. M.; Reeves, S.; Bates, G. P.; Luthi-Carter, R.; Lowden, P. A.; Kazantsev, A. G. A brain-permeable small molecule reduces neuronal cholesterol by inhibiting activity of sirtuin 2 deacetylase. ACS Chem. Biol. 2011, 6, 6, 540-546.) In silico screening of a ChemBridge diverse library identified AK-7, the first brain-permeable selective SIRT2 inhibitor (IC50=15.5 μM) that reduces cholesterol in neuronal models and protects an in vitro model of HD. (Id.)
Notwithstanding the excellent pharmacologic properties of such sulfobenzoic acid derivatives, further lead optimization of the scaffold is required for CNS drug development to achieve increased potency and metabolic stability, en route to preclinical efficacy testing in HD. For instance, C2-8, AK-1, and AK-7 are characterized by the low aqueous solubility, high clogP, and low plasma and microsomal metabolic stability. As a result, there remains an on-going need for medicinal chemistry modification to, for instance: (1) enhance potency and favorable pharmacokinetic properties; (2) enhance the water solubility (lower the log P) and lower the molecular weight; (3) probe chemical space to define a structure activity relationship (SAR).

As used herein, “aryl” refers to an aromatic monocyclic hydrocarbon ring system or a polycyclic ring system in which two or more aromatic hydrocarbon rings are fused (i.e., having a bond in common with) together or at least one aromatic monocyclic hydrocarbon ring is fused to one or more cycloalkyl and/or cycloheteroalkyl rings. An aryl group can have 6 to 24 carbon atoms in its ring system (e.g., C6-20 aryl group), which can include multiple fused rings. In some embodiments, a polycyclic aryl group can have 8 to 24 carbon atoms. Any suitable ring position of the aryl group can be covalently linked to the defined chemical structure. Examples of aryl groups having only aromatic carbocyclic ring(s) include phenyl, 1-naphthyl (bicyclic), 2-naphthyl (bicyclic), anthracenyl (tricyclic), phenanthrenyl (tricyclic), pentacenyl (pentacyclic), and like groups. Examples of polycyclic ring systems in which at least one aromatic carbocyclic ring is fused to one or more cycloalkyl and/or cycloheteroalkyl rings include, among others, benzo derivatives of cyclopentane (i.e., an indanyl group, which is a 5,6-bicyclic cycloalkyl/aromatic ring system), cyclohexane (i.e., a tetrahydronaphthyl group, which is a 6,6-bicyclic cycloalkyl/aromatic ring system), imidazoline (i.e., a benzimidazolinyl group, which is a 5,6-bicyclic cycloheteroalkyl/aromatic ring system), and pyran (i.e., a chromenyl group, which is a 6,6-bicyclic cycloheteroalkyl/aromatic ring system). Other examples of aryl groups include benzodioxanyl, benzodioxolyl, chromanyl, indolinyl groups, and the like. In some embodiments, aryl groups can be substituted as described herein. In some embodiments, an aryl group can have one or more halogen substituents, and can be referred to as a “haloaryl” group. Perhaloaryl groups, i.e., aryl groups where all of the hydrogen atoms are replaced with halogen atoms (e.g., —C6F5), are included within the definition of “haloaryl.” In certain embodiments, an aryl group is substituted with another aryl group and can be referred to as a biaryl group. Each of the aryl groups in the biaryl group can be substituted as disclosed herein.
As used herein, “heteroaryl” refers to an aromatic monocyclic ring system containing at least one ring heteroatom selected from oxygen (O), nitrogen (N), sulfur (S), silicon (Si), and selenium (Se) or a polycyclic ring system where at least one of the rings present in the ring system is aromatic and contains at least one ring heteroatom. Polycyclic heteroaryl groups include those having two or more heteroaryl rings fused together, as well as those having at least one monocyclic heteroaryl ring fused to one or more aromatic carbocyclic rings, non-aromatic carbocyclic rings, and/or non-aromatic cycloheteroalkyl rings. A heteroaryl group, as a whole, can have, for example, 5 to 24 ring atoms and contain 1-5 ring heteroatoms (i.e., 5-20 membered heteroaryl group). The heteroaryl group can be attached to the defined chemical structure at any heteroatom or carbon atom that results in a stable structure. Generally, heteroaryl rings do not contain O—O, S—S, or S—O bonds. However, one or more N or S atoms in a heteroaryl group can be oxidized (e.g., pyridine N-oxide, thiophene S-oxide, thiophene S,S-dioxide). Examples of heteroaryl groups include, for example, the 5- or 6-membered monocyclic and 5-6 bicyclic ring systems shown below.

Generally, a chemical group (e.g., —Ar—) is understood to be divalent by the inclusion of the two bonds before and after the group.
    
    


At various places in the present specification, substituents are disclosed in groups or in ranges. It is specifically intended that the description include each and every individual subcombination of the members of such groups and ranges. For example, the term “C1-6 alkyl” is specifically intended to individually disclose C1, C2, C3, C4, C5, C6, C1-C6, C1-C5, C1-C4, C1-C3, C1-C2, C2-C6, C2-C5, C2-C4, C2-C3, C3-C6, C3-C5, C3-C4, C4-C6, C4-C5, and C5-C6 alkyl. By way of other examples, an integer in the range of 0 to 40 is specifically intended to individually disclose 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, and 40, and an integer in the range of 1 to 20 is specifically intended to individually disclose 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20.

Compounds described herein can contain an asymmetric atom (also referred as a chiral center) and some of the compounds can contain two or more asymmetric atoms or centers, which can thus give rise to optical isomers (enantiomers) and diastereomers (geometric isomers). The present teachings include such optical isomers and diastereomers, including their respective resolved enantiomerically or diastereomerically pure isomers (e.g., (+) or (−) stereoisomer) and their racemic mixtures, as well as other mixtures of the enantiomers and diastereomers. In some embodiments, optical isomers can be obtained in enantiomerically enriched or pure form by standard procedures known to those skilled in the art, which include, for example, chiral separation, diastereomeric salt formation, kinetic resolution, and asymmetric synthesis. The present teachings also encompass cis- and trans-isomers of compounds containing alkenyl moieties (e.g., alkenes, azo, and imines). It also should be understood that the compounds of the present teachings encompass all possible regioisomers in pure form and mixtures thereof. In some embodiments, the preparation of the present compounds can include separating such isomers using standard separation procedures known to those skilled in the art, for example, by using one or more of column chromatography, thin-layer chromatography, simulated moving-bed chromatography, and high-performance liquid chromatography. However, mixtures of regioisomers can be used similarly to the uses of each individual regioisomer of the present teachings as described herein and/or known by a skilled artisan.
Syntheses of 3-sulfonamide benzoate derivatives began from the commercially available benzoic acid or 3-methoxybenzoic acid (1-2) using procedures described in the literature (Scheme 1). (See, e.g., Nie, Z.; Perretta, C.; Lu, J.; Su, Y.; Margosiak, S.; Gajiwala, K. S.; Cortez, J.; Nikulin, V.; Yager, K. M.; Appelt, K.; Chu, S. Structure-based design, synthesis, and study of potent inhibitors of beta-ketoacyl-acyl carrier protein synthase III as potential antimicrobial agents. J. Med. Chem. 2005, 48, 5, 1596-1609; and Wrobel, J.; Green, D.; Jetter, J.; Kao, W.; Rogers, J.; Perez, M. C.; Hardenburg, J.; Deecher, D. C.; Lopez, F. J.; Arey, B. J.; Shen, E. S. Synthesis of (bis)sulfonic acid, (bis)benzamides as follicle-stimulating hormone (FSH) antagonists. Bioorg. Med. Chem. 2002, 1, 3, 639-656.) The synthetic route started by sulfonylation of benzoic acid analogs to produce 3 and 4, which were coupled with primary or secondary anilines (for 5-20) or with azepane (for 21 and 22) in pyridine to generate the corresponding sulfonamide derivatives. The carboxylic acid was then coupled with aniline or other heterocyclic rings using N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (EDCI) and 4-(dimethylamino)pyridine (DMAP) to generate the final compounds (23-152). DMAP was removed in the last step of the 23-42 syntheses to overcome polymerization that has been observed. The commercially available aminothioanisole derivatives (153 and 154) were used to synthesize the corresponding sulfoxides (155 and 156) using self-catalyzed selective oxidation, and sulfones (157 and 158) using sodium tungstate and an excess of hydrogen peroxide (Scheme 2). (See, e.g., Beller, M.; Shi, F.; Tse, M. K.; Kaiser, H. M. Self-catalyzed oxidation of sulfides with hydrogen peroxide: A green and practical process for the synthesis of sulfoxides. Adv. Synth. Cata. 2007, 349, 16, 2425-2430; and Biava, M.; Porretta, G. C.; Poce, G.; Supino, S.; Forli, S.; Rovini, M.; Cappelli, A.; Manetti, F.; Botta, M.; Sautebin, L.; Rossi, A.; Pergola, C.; Ghelardini, C.; Vivoli, E.; Makovec, F.; Anzellotti, P.; Patrignani, P.; Anzini, M. Cyclooxygenase-2 inhibitors. 1,5-diarylpyrrol-3-acetic esters with enhanced inhibitory activity toward cyclooxygenase-2 and improved cyclooxygenase-2/cyclooxygenase-1 selectivity. J. Med. Chem. 2007, 50, 22, 5403-5411.








The N-methyl-4-(methylthio)aniline (161) and 5-chloro-N-methylpyridin-2-amine (162) were synthesized from the corresponding commercially available demethylated derivatives (159 and 160, respectively) using the Chan-Lam selective monomethylation procedure, which involves copper(II)-promoted coupling of anilines and methylboronic acid (Scheme 3). (See, e.g., Gonzalez, I.; Mosquera, J.; Guerrero, C.; Rodriguez, R.; Cruces, J. Selective monomethylation of anilines by Cu(OAc)2-promoted cross-coupling with MeB(OH)2. Org. Lett. 2009, 11, 8, 1677-1680.) Subsequently, 161 was oxidized to the sulfoxide (163) and sulfone (164) intermediates as described above.
The sulfonamide moiety was replaced by sulfone, sulfoxide, or thioether moieties as described in Scheme 4. Commercially available 3-mercaptobenzoic acid and 3-benzyl bromide derivatives were coupled to yield 3-(benzylthio)benzoic acid derivatives (165-167), which were subjected to oxidation with excess H2O2 in acetic acid to generate the corresponding sulfone (168-170), or with one equivalent of H2O2 to form the sulfoxide intermediates (184 and 185). Subsequently, the sulfone, sulfoxide, and thioether derivatives were coupled with aniline, pyridine, or pyridazine amines using EDCI and DMAP to form the final compounds (171-183, 186-189).




The phenolic analogs (35, 57, 58, 71, 85, 152) were generated from their parent anisole compounds (29, 55, 59, 70, 84, 151, respectively) using one molarity of boron tribromide (BBr3) in DCM as described in the literature. Reduction of the acetyl group of 103, 104, and 107 was performed using sodium borohydride (NaBH4) in anhydrous methanol to generate the secondary alcohol derivatives 126, 127, and 128, respectively. (See, e.g., Watts, P.; Wiles, C.; Haswell, S. J. Clean and selective oxidation of aromatic alcohols using silica-supported Jones' reagent in a pressure-driven flow reactor. Tetrahedron Lett. 2006, 47, 30, 5261-5264.)




To evaluate the potency and selectivity of the synthesized compounds robust, sensitive, and quantitative, biochemical sirtuin deacetylation assays were employed. (SIRT2 then SIRT1 and SIRT3 for selectivity). Sirtuin activity was assessed using the Fluor-de-Lys assay with recombinant active enzymes SIRT1, SIRT2, and the catalytically active fragment of SIRT3, as described in the literature. (See, Outeiro, T. F.; Kontopoulos, E.; Altmann, S. M.; Kufareva, I.; Strathearn, K. E.; Amore, A. M.; Volk, C. B.; Maxwell, M. M.; Rochet, J. C.; McLean, P. J.; Young, A. B.; Abagyan, R.; Feany, M. B.; Hyman, B. T.; Kazantsev, A. G. Sirtuin 2 inhibitors rescue alpha-synuclein-mediated toxicity in models of Parkinson's disease. Science 2007, 317, 5837, 516-519.) Compounds were tested at a single 10 μM dose in the primary SIRT2 assay and counter-screened in SIRT1 and SIRT3 assays as described. AK-1 was included as the reference compound with each assay. Hits demonstrating SIRT2 inhibition activity equal to or better than AK-1 in the SIRT2 assay were selected for dose-response studies, which were performed with five doses in the primary SIRT2 assay in at least two independent experiments, including a direct side-by-side comparison of SIRT2 inhibition by AK-1. Those compounds also were subjected to SIRT1 and SIRT3 assays to determine sirtuin selectivity. The dose-response assays identified 47, 64, 90, 102, 106, 115, and 126 as significantly more potent SIRT2 inhibitors than AK-1, while a number of analogs, 51, 52, 59, 61, 71, 103, 109, 117, and 174 had either equal or just slightly better potency.
High potency and selectivity in in vitro biochemical assays do not ensure compound cell permeability and bioactivity. To that end, a confirmatory test of SIRT2 inhibition activity was performed in live cells. This scaffold showed a high degree of selectivity; most of the compounds were totally inactive in SIRT1 and SIRT3 inhibitory assays. Compounds 43, 56, 106, and 115 showed minimal SIRT1 inhibition, while 41, 106, and 58 displayed minimal SIRT3 inhibition. The only compound that significantly inhibited SIRT1 was 31, a 2-thiazole derivative that was totally inactive as a SIRT2 and SIRT3 inhibitor but inhibited SIRT1 by 65% at 10 μM.
To assess SIRT2 inhibition activity in cells, an increase in α-tubulin K40 acetylation (α-tubulin is a substrate for SIRT2) in neuronal N2a and in wild type and HD ST141 cell lines was measured. In this bioactivity test, extracts from compound-treated cells were resolved on SDS-PAGE and subjected to Western analysis using primary antibodies specific to K40 acetylated α-tubulin. Trichostatin A (TSA), a potent HDAC inhibitor, was used as a positive control. To normalize the levels of acetylated α-tubulin we used total α-tubulin and GADPH proteins, detected by Western reactive antibodies specific to total α-tubulin and GADPH. All compounds that showed confirmed SIRT2 inhibitory activities were selected for cell-based acetylation assays. Sixteen compounds were tested, and all of them, except 115, increased α-tubulin K40 acetylation in the two cell lines in a dose-dependent manner. Analog 115 did not show any significant increase in α-tubulin acetylation in either cell line. FIGS. 2A-B show the bioactivity of 61 and 64 in N2a cells at three tested concentrations (10, 25, and 50 μM). Toxicity of the compounds was monitored in both cell lines, and most of them were non-toxic up to 50 μM in a 6 h treatment. Compound 90 was toxic at 50 μM in N2a cells and partially toxic at 25 μM, but no toxicity was observed in WT st14a cells up to an 18 h treatment.
Because of low aqueous solubility (high lipophilicity) and metabolic instability, the initial stage of structural modification involved water solubility enhancement that would potentially improve the ADMET properties. Lipinski's Rule of Five and Veber's rules were adopted for the synthesis criteria, limiting the range for molecular weight to ≦500, calculated octanol-water partition coefficient (ClogP) to ≦5, the number of hydrogen bond donors (OH's and NH's) and hydrogen bond acceptors (N's and O's) to ≦10, the number of rotatable bonds ≦10, the polar surface area <90 Å2. The ideal Clog P value for BBB penetration is 2≦log P≦4; therefore, most of the compounds that were synthesized were in that range. The syntheses are straightforward, mostly only 3-5 steps. Syntheses of such analogs were not conducted at random; an initial structural hypothesis was proposed, which drove the synthetic effort. The synthesized compounds were tested for enhancement of solubility and activity, and the hypotheses were refined and adjusted according to the evolving results.
The following structural modification strategies were applied to the C2-8 and AK-1 scaffolds to improve their solubility: (1) the A, B, and C phenyl rings (FIG. 1) of C2-8 and AK-1 were replaced with five- and six-membered heterocyclic ring(s), e.g., pyridine, pyrimidine, pyridazine, thiazole, oxazole, isoxazole, and oxadiazole rings—to increase aqueous solubility in drug design. Heterocyclic rings were found to be tolerated on ring A of C2-8 but not on ring C, as described, below; (2) hydrophobic groups: halogens of C2-8 and AK-1 were replaced with more polar and hydrophilic groups, such as hydroxyl, methoxyl, amino, cyano, carboxyl, acetyl, methylsulfoxide, methylsulfone, and acetamide groups. Four hydrophilic groups were found to increase or at least maintain the SIRT2 inhibitory activities: the cyano, sulfoxide, sulfone, and acetyl groups, specifically on ring A of C2-8; (3) the sulfonamide was replaced with sulfone, sulfoxide, and sulfide, and phenylamide planarity was disrupted by introduction of a methylene group between them. Replacing the N—CH3 group with a CH2 moiety was tolerated and a good strategy to overcome the metabolic instability by demethylation, as described below; (4) the active derivatives from the above-mentioned strategies were combined into one compound. The structures of the new compounds are summarized along with their SIRT2 inhibitory activities at 10 μM in Table 1 and Table 2, below.
An understanding of the SAR of the sulfobenzoic acid derivatives is not only useful for the synthesis of more active analogs, but also for selecting optimal approaches for increasing solubility without significant loss in activity. With respect to certain non-limiting embodiments of this invention, FIG. 3 summarizes several SAR conclusions from the SIRT2 inhibition assays. Although C2-8 and AK-1 both contain a 3-sulfonyl benzoate scaffold, the SAR shows that their analogs have a few structurally distinct features, which differentiate the two scaffolds.
On the basis of the SIRT2 inhibitory activities of analogs synthesized here and those tested in previous screening studies, a SAR of the C2-8 scaffold can be summarized as follows: (1) R1 on ring A of C2-8 should be at the para position; however, small groups (e.g., F) at the ortho position are tolerated; (2) R1 should be electron withdrawing, but both hydrophobic and hydrophilic substituents are tolerated; (3) Six-membered heterocyclic rings in place of benzene ring A are tolerated, but not five-membered heterocyclic rings; (4) The sulfonamide nitrogen must be methylated but the N-methyl group is not essential for activity. Sulfide is more potent than sulfoxide and sulfone in the order described in FIG. 3; (5) R3 is optimal at the para position; pyridinyl modification of ring C is tolerated; (6) R3 should be electron withdrawing, and both hydrophobic and hydrophilic substituents are tolerated; (7) There is no apparent trend for R2 on ring B; H, F, Cl, Br, CH3, OCH3 groups are tolerated at this position.
A SAR for the AK-1 scaffold also has been studied and can be summarized as follows: (1) AK-1 derivatives have optimum activities when R1 is at the meta position, not para, which is favored for C2-8 analogs; (2) R1 should have electron-withdrawing or weakly electron-donating properties; (3) Similar to C2-8, both hydrophobic and hydrophilic substituents are tolerated at R1; (4) Five- and six-membered heterocyclic rings in place of benzene ring A were inactive; (5) Hexamethyleneimine (seven-membered ring) is better than smaller cyclic ring amines. AK-1 analogs that contain a 4-methylpiperidine group were more potent than those containing a piperidine group. These results suggest that ring C may be involved in a hydrophobic interaction in a binding pocket; (6) There is no apparent trend for R2 on ring B; H, F, Cl, Br, CH3 groups are tolerated at this position, and OCH3 gave opposite results.
In vitro ADME studies were carried out at Apredica, Inc. (Watertown, Mass.). The solubility of 51 and 59 in PBS was moderately increased by two- and four-fold, respectively, compared to AK-1. The plasma protein binding for both compounds is high; 99.8% for 51 and 99.1% for 59. Microsomal stability is still low; neither compound was stable in mouse and human microsomes after 60 minutes (0% remaining for 51 and 16% for 59). The efflux ratio is 0.7 and 1.7 for 51 and 59 respectively, which suggests that they are not substrates for P-glycoprotein or other active transporters.
In an attempt to better understand the microsome instability of these compounds, 51 and 59 were submitted for metabolite identification studies at Apredica, Inc. The N-demethylated metabolite of 51 was detected, which we had already tested (26) and found to be inactive in the SIRT2 assay. This rapid metabolism of 51 to an inactive metabolite explains why this compound appears to have low concentration in blood and in brain homogenate. Other active compounds became inactive when the N-methyl group was removed. In an attempt to overcome this metabolic inactivation, the sulfonamide moiety was replaced with sulfone, sulfoxide, and thioether analogs as shown in Scheme 4 and Table 3. The replacement of the N—CH3 group with CH2 (171-180) was tolerated in 174, 175, and 176 compared to the parent analog (64, 59, and 71, respectively). Other sulfone derivatives were less potent than the corresponding sulfonamide analogs.
The major metabolite from 59 is the corresponding sulfone (61; the sulfoxide is oxidized to sulfone). Unlike the loss in activity when the N—CH3 group is demethylated, oxidation of the sulfoxide to the sulfone produces a more potent compound in both the SIRT2 and cell-based tubulin deacetylation assays. One of the most potent compounds in that series, however, is the corresponding nitrile (64), which avoids potential sulfur oxidation because there is no sulfoxide group. Compound 71, with a cyanopyridine analog is also more potent than 59; 174, with a cyano in place of the sulfoxide and a CH2 group in place of the N—CH3 group also is more potent than 59.
The other significant result from the metabolism identification study was that no amide hydrolysis products were detected in microsomal incubations and limited hydrolysis was detected in plasma (half-lives >2 h). This supports the stability of the amide linkage. Detailed ADME studies results with 51 and 59 and the experimental procedures are provided, below.
As mentioned earlier, one of the few hydrophilic functional groups used to enhance solubility that was found to be active in SIRT2 inhibition is the acetyl group. However, it is well known that it is susceptible to reduction to the corresponding secondary alcohol by aldo-keto reductases. To test if the secondary alcohol derivatives maintain SIRT2 inhibitory activity, the acetyl analogs 103, 104, and 107 were reduced to their corresponding alcohols 126, 127, and 128. Compound 126 maintained inhibitory activity (45%) with SIRT2, comparable to 103 (40%)
As demonstrated, starting with C2-8 and AK-1 as lead compounds, structural alteration enhanced water solubility and metabolic stability. Synthesis of 187 representative, non-limiting compounds allowed formulation of a SAR for these two classes of compounds. No sulfonamide is necessary; sulfide, sulfoxide, and sulfone can substitute. Substituents on the aromatic ring include cyano, acetyl, 1-hydroxyethyl, methylthio.
More specifically, seven new analogs were found to be much more potent SIRT2 inhibitors than AK-1 with high selectivity over SIRT1 and SIRT3. Nine new analogs were as potent or slightly more potent than AK-1 with high SIRT1 and SIRT3 selectivity. These compounds were subjected to a secondary screen for SIRT2 inhibition in live cells, which measured an increase in α-tubulin K40 acetylation (α-tubulin is a substrate for SIRT2) in neuronal N2a and in wild type and HD ST141 cell lines. Fifteen compounds increased α-tubulin K40 acetylation in both cell lines in a dose-dependent manner, and most of them were non-toxic in both cell lines up to 50 μM in a 6 h treatment.
Methods of the present invention can also, as would be understood by those skilled in the art, be extended to or include methods using or in conjunction with a pharmaceutical composition comprising an inhibitor compound of the sort described herein in a physiologically or otherwise suitable formulation. In some embodiments, the present invention includes one or more such inhibitors, as outlined above or discussed more fully below, formulated into compositions together with one or more physiologically tolerable or acceptable diluents, carriers, adjuvants or vehicles that are collectively referred to herein as carriers. Compositions suitable for such contact or administration can comprise physiologically acceptable sterile aqueous or non-aqueous solutions, dispersions, suspensions or emulsions. The resulting compositions can be, in conjunction with the various methods described herein, for administration or contact with a human/animal sirtuin enzyme expressed or otherwise present therein. Whether or not in conjunction with a pharmaceutical composition, “contacting” means that a sirtuin enzyme and one or more inhibitor compounds are brought together for purpose of binding and/or complexing such an inhibitor compound to the enzyme. Amounts of a compound effective to affect or otherwise inhibit a sirtuin enzyme may be determined empirically, and making such determinations is within the skill in the art. Inhibition, affecting or otherwise modulating sirtuin enzyme activity includes both reduction and/or mitigation, such results as can be confirmed through an increase in substrate acetylation.
It is understood by those skilled in the art that dosage amount will vary with the activity of a particular inhibitor compound, disease state, route of administration, duration of treatment and like factors well-known in the medical and pharmaceutical arts. In general, a suitable dose will be an amount which is the lowest dose effective to produce a therapeutic or prophylactic effect. If desired, an effective dose of such a compound, pharmaceutically acceptable salt thereof or related composition may be administered in two or more sub-doses, administered separately over an appropriate period of time.
Methods of preparing pharmaceutical formulations or compositions include the step of bringing an inhibitor compound into association with a carrier and, optionally, one or more additional adjuvants or ingredients. For example, standard pharmaceutical formulation techniques can be employed, such as those described in Remington's Pharmaceutical Sciences, Mac Publishing Company, Easton, Pa.
Regardless of composition or formulation, those skilled in the art will recognize various avenues for medicament administration, together with corresponding factors and parameters to be considered in rendering such a medicament suitable for administration. Accordingly, with respect to one or more non-limiting embodiments, the present invention provides for use of one or more sirtuin inhibitor compounds for the manufacture of a medicament for therapeutic use in the treatment of Huntington's disease or the prevention thereof.

Multiplicities are indicated by s (singlet), d (doublet), t (triplet), q (quartet), p (pentet), h (heptet), m (multiplet), and br (broad). The HREIMS experiments were conducted on a 6200-TOF LCMS (Agilent, Santa Clara, Calif.) equipped with a multimode source (mixed source that can ionize the samples alternatively by ESI or APCI). Electrospray mass spectra (ESMS) were obtained using an LCQ-Advantage with methanol as the solvent in the positive ion mode. Analytical HPLC analyses were performed on a Beckman HPLC system using a Vydac C18 column (4.6×150, 5 μm Phenomenex) and isocratic elution (CH3CN: H2O; 60:40) with UV detection set at 305 and 220 nm to verify the purity of tested compounds. Except for compounds 28, 75, and 147 a purity of >95% has been established for all final tested compounds. Compound 28, 75, and 147 achieved 89%, 90%, and 88% purity level, respectively. Except as otherwise indicated, all reactions were magnetically stirred and monitored by analytical thin-layer chromatography using Whatman precoated silica gel flexible plates (0.25 mm) with F254 indicator or Merck precoated silica gel plates with F254 indicator. Visualization was accomplished by UV light (256 nm). Flash column chromatography was performed using silica gel 60 (mesh 230-400) supplied by E. Merck. Yields refer to chromatographically and spectrographically pure compounds, unless otherwise noted. Commercial grade reagents and solvents were used without further purification except as indicated below.
General Chemical Reaction Procedures.

A mixture of 1 (5 g, 40.94 mmol) or 2 (5 g, 32.86 mmol) in chlorosulfonic acid (20 mL) was heated to 65° C. in an oil bath for 4 h, after which time TLC indicated complete conversion of the starting material to the intermediates, 3-(chlorosulfonyl)benzoic acid (3) and 3-(chlorosulfonyl)-4-methoxybenzoic acid (4), respectively. The reaction mixture was slowly poured over ice and filtered. The solid was dried in vacuo to yield intermediates 3 (7.90 g, 87%) and 4 (6.40 g, 86%), which were carried forward without further purification.
(B) Formation of the sulfonamide bonds. Sulfonyl chloride derivative 1 or 2 (3.99 mmol) was added gradually to a mixture of substituted amine (4.39 mmol) and pyridine (2 mL) in EtOAc with stirring at 0° C. The reaction mixture was stirred at room temperature until the TLC indicated complete conversion of sulfonyl chloride to the sulfonamide intermediate. The reaction mixture was dissolved in DCM and extracted (2×) with 10% NaOH. After the aqueous layer was acidified with 2 N HCl, the precipitate was collected by filtration, washed with H2O, and dried in vacuo to give the desired products (5-22), which were carried forward without further purification.
