Description

TECHNICAL FIELD

[0001] The present invention relates to novel compounds having histone deacetylase (HDAC) inhibitory activity, optical isomers thereof, pharmaceutically acceptable salts thereof, their use for the preparation of medicaments for the treatment of HDAC-mediated diseases, a pharmaceutical composition comprising the same, a treatment method using the composition, and a preparation method thereof.

BACKGROUND ART

[0002] The cellular transcriptional regulation is a complex biological process. One of the basic principles is the post-translation modification of histone proteins H2A/B, H3 and H4 that form the octameric histone core complex. The complex N-terminal modifications at lysine residues by acetylation or methylation and at serine residues by phosphorylation constitute part of the so-called "histone code" (Stahl & Ellis, Nature 403, 41-45, 2000).

[0003] In a simple model, acetylation of positively charged lysine residues decreases affinity to negatively charged DNA, thus transcription factors may be easily entered.

[0004] Histone acetylation and deacetylation is catalysed by histone acetyltransferases (HATs) and histone deacetylases (HDACs), respectively. The HDAC is associated with transcriptional repressor complexes, switching chromatin to a transcriptionally inactive, silent structure (Marks et al. Nature Cancer Rev 1, 189-202, 2001). The opposite holds true for certain HATs which are associated with transcriptional activator complexes. Three different classes of HDACs, located in the nucleus, have been described so far, namely, class I (HDAC 1-3, 8; Mr=42-55 kDa) sensitive towards inhibition Trichostatin A (TSA), class II (HDAC 4-7, 9, 10; Mr=120-130 kDa) sensitive to TSA, and class III (Sir2) which are quite distinct by their NAD+ dependency and TSA insensitivity.

[0005] Inhibitors of histone deacetylases (HDACs) constitute a new class of anticancer drugs with differentiation and apoptosis activity. By targeting histone deacetylases (HDACs), the HDAC inhibitors affect histone (protein) acetylation and chromatin structure, inducing a complex transcriptional reprogramming, exemplified by reactivation of tumor suppressor genes and repression of oncogenes. In addition to generating acetylation of N-terminal lysine residue in core histone protein, there are non-histone targets important for cancer cell biology, including heat-shock-protein (HSP90), tubulin or p53 tumor suppressor protein. Therefore, the HDAC inhibitors can be used for the treatment of cancers as well as inherited metabolic diseases, autoimmune diseases, etc., since the efficacy in animal models for inflammatory diseases, rheumatoid arthritis, and neurodegeneration has been shown.

[0006] Examples of histone deacetylase-mediated diseases include cell proliferative diseases including malignant tumors such as cancers, etc., autosomal dominant diseases such as Huntington's diseases, etc., inherited metabolic diseases such as cystic fibrosis, hepatic fibrosis, kidney fibrosis, pulmonary fibrosis, skin fibrosis, etc, autoimmune diseases such as rheumatoid arthritis, etc., acute and chronic neurological diseases such as diabetes, stroke, etc., hypertrophy such as cardiac hypertrophy, etc., hemorrhagic heart failure, amyotrophic lateral sclerosis, glaucoma, ocular diseases (associated with angiogenesis), Alzheimer's disease, etc.

[0007] HDAC inhibitors known up to now can be classified into four categories according to their structures: 1) short chain fatty acids (butyric acid, valproic acid); 2) hydroxamic acids (trichostatin A, SAHA, LBH-589); 3) cyclic peptides (desipeptide); and 4)benzamide (MS-275, MGCD-0103) (International Journal of Onocology 33, 637-646, 2008). These many HDAC inhibitors (SAHA, LBH-589, MS-275, etc.) effectively induce growth inhibition, differentiation, and apoptosis of various transformed cells in culture medium as well as in animal models (Marks, P. A et. al., Curr Opin Oncol. 2001. 13. 477-483), and some HDAC inhibitors such as SAHA, LBH-589, MS-275, etc. are clinically evaluated for the treatment of various cancers (Johnstone, R. W Nat. Rev. Drug Discov. 2002 1. 287-299). Typical examples of HDAC inhibitor compounds that are currently known include hydroxamate compounds, such as SAHA (U.S. Pat. No. 771,760, Zolinza, Vorinostat), PXD101 (WO 02/30879, Belinostat), LBH-589 (WO 02/22577, Panobinostat), and benzamide compounds such as MS-275 (EP8799) and MGCD0103 (WO 04/69823). Among these compounds, SAHA was approved on October 2006 and has been used for the treatment of CTCL (cutaneous T-cell lymphoma). Diseases for which medicine is efficacious have been additionally expanded, but it is known that there are drawbacks in terms of effectiveness and side effects (Cancer Res 2006, 66, 5781-5789).

[0008] That is, although many HDAC inhibitors have been reported to date, most of the HDAC inhibitors have drawbacks in terms of efficacy and side effects. Therefore, in order to overcome these drawbacks, there is a continuous need to develop an effective HDAC inhibitor with high selectivity and less side effects (Mol Cancer Res, 5, 981, 2007).

Determination of Inhibition of HDAC Activities (In Vitro)

[1208] Selective HDAC6 inhibitors are critical for the selectivity of HDAC1 inhibition, which causes side effects, and thus the selectivity of HDAC1/6 enzymes and the cell selectivity (HDAC1: Histone acetylation/HDAC6: Tubulin acetylation) were determined.

[1209] 1. Test of HDAC Activities (HDAC1 and HDAC6)

[1210] The HDAC inhibitory activities of test materials were measured using the HDAC1 Fluorimetric Drug Discovery Assay Kit (Enzolifesciences: BML-AK511) and HDAC6 human recombinant (Calbiochem: 382180). In the HDAC1 assay, the samples were treated with concentrations of 100, 1000, and 10000 nM, and in the HDAC6 assay, the samples were treated with concentrations of 0.1, 1, 10, 100, and 1000 nM. After the treatment of the samples, the samples were reacted at 37.degree. C. for 60 minutes, treated with a developer, and then reacted at 37.degree. C. for 30 minutes. Then, the fluorescence intensity (Ex 390, Em 460) was measured using the FlexStatin 3 (Molecular device).

[1211] The results are shown in Table 14.

[1212] As shown in Table 14, the novel urea derivatives of the present invention exhibit excellent HDAC1/6 enzyme selectivity.

[1213] The inhibitory activities of Compounds 255 and 374 on all HDACs were confirmed (by Reaction Biology Corp.). The results are shown in Table 15:

TABLE-US-00016 TABLE 15 HDAC inhibitory activities of Compounds 255 and 374 uM 255 374 HDAC 1 0.16 2.12 HDAC 2 0.69 4.88 HDAC 3 1.63 10.3 HDAC 4 6.86 16.4 HDAC 5 8.27 ND HDAC 6 0.001 0.005 HDAC 7 1.5 5.25 HDAC 8 0.65 2.07 HDAC 9 3.52 10.3 HDAC 10 1.47 16.2 HDAC 11 0.78 8.42 Selectivity 160 424 (HDAC6/1)

[1214] As shown in Table 15, it was found that Compound 255 had a selectivity of 160 times for HDAC6: 0.001 uM and HDAC1: 0.16 uM and Compound 374 had a selectivity of 424 times for HDAC6: 0.005 uM and HDAC1: 2.12 uM.

[1215] 2. Determination of Acetylation of Tubulin, Histone H3 and Histone H4 in Cells

[1216] To determine the selectivity for HDAC6 in cells, the acetylation levels of Tubulin, Histone H3 and Histone H4 depending on the concentration of compounds were measured by Western blot.

[1217] RPMI8226 (1.0.times.106 cells/well) cells were seeded on six-well plates and treated with drugs (Compounds 255 and 374) at each concentration. After 24 hours, the proteins were extracted with RIPA buffer and quantified by the Bradford method. 25 g of protein was lysed in sample buffer, electrophoresed on a 4-12% gradient gel, and then transferred to nitrocellulose membranes for 50 minutes. Then transferred protein was blocked with 5% skim milk for 1 hour. Anti-acetyl H3 (1:2,000), anti-acetyl H4 (1:5,000), anti-acetyl tubulin (1:5,000), and anti-.beta.-actin antibody (1:10,000) were added into 5% skim milk, and the membranes were immersed in the skim milk, reacted at 4.degree. C. for 16 hours, and then washed three times for 10 minutes each with 1.times.TBS-T. Then, IgG-HRP antibody (1:5,000) was added into 5% skim milk, and then the membranes were immersed in the skim milk, reacted at room temperature for 40 minutes, and then washed three times for -10 minutes each with 1.times.TBS-T. Then, the acetylation levels were determined with a LAS 3000 using ECL solution.

[1218] The results are shown in FIGS. 1 and 2.

[1219] As shown in FIGS. 1 and 2, it was found that both Compound 255 (FIG. 1) and Compound 374 (FIG. 2) had excellent activities at low concentrations as tubulin acetylation (HDAC6) was expressed at a low concentration of about 10 nM. On the contrary, it was found that Compound 255 and Compound 374 had little or no activity at low concentrations as histone acetylation (HDAC1) was expressed at a concentration of 1 uM of Compound 255 and 10 uM of Compound 374. Therefore, it was found from the difference in the expressed concentration of tubulin and histone that the novel urea compounds of the present invention have excellent cell selectivity.

Efficacy of Compounds 254, 255 and 374 in Collagen-Induced Arthritis Models

[1220] The efficacy of the novel urea derivatives of the present invention on the treatment of arthritis in collagen-induced arthritis models was determined.

[1221] An emulsion was prepared by mixing bovine collagen type II (Chondrex) and complete Freund's adjuvant (Chondrex) at a ratio of 1:1 until the viscosity was measured using a 1 ml pipette. Each 100 ul of emulsion was intradermally injected into the tail of DBA/1J mice for the first immunization. After 21 days, an emulsion was prepared by mixing bovine collagen type II and incomplete Freund's adjuvant (Chondrex) at a ratio of 1:1 by the same method as above. Each of 100 ul of emulsion was intradermally injected into the upper part of the tail of DBA/1J mice for the second boosting immunization. After the second boosting immunization, the mice were grouped according to body weight, the test drug was administered to each group, and the effects of the test drugs were measured by measuring the clinical score and the body weight. The clinical scores were assigned from 0 to 4, and the total clinical score was determined by evaluating the feet of each mouse and summing up the scores (normal: 0, most severe edema: 16). That is, the efficacy in the arthritis models was evaluated with the severity of edema of the joint, and a higher score was assigned to more severe edema.

[1222] The above experimental results are shown in FIGS. 3 and 4.

[1223] As shown in FIG. 3, the clinical score of the vehicle group was 11.6, and that of the group treated with Compound 254 in an amount of 30 mg/kg twice a day was 6.4, from which it can be seen that the arthritis symptoms were improved by more than 40%. Moreover, the clinical scores of the groups treated with Compound 255 in an amount of 10 and 30 mg/kg twice a day were 5.2 and 6.5, from which it can be seen that the arthritis symptoms were improved by more than 50%. Moreover, as shown in FIG. 4, the clinical score of the vehicle (v) group was 6.7, and those of the group treated with Compound 374 at different concentrations were 2.8 and 2.5, from which it can be seen that the arthritis symptoms were improved by more than 60%. That is, severe edema was observed in the vehicle group untreated with no drugs, while the edema was significantly reduced in the group treated with the novel urea compounds of the present invention, from which it can be seen that the arthritis symptoms were significantly reduced.

Example 171

Efficacy of Compounds 255, 374 and 461 in Adjuvant-Induced Arthritis Models

[1224] The efficacy of the novel urea derivatives of the present invention on the treatment of arthritis in adjuvant-induced arthritis models was determined.

[1225] Complete Freund's Adjuvant (Chondrex) containing 10 mg/mL Heat killed mycobacteria toxin was sufficiently mixed, and then 100 uL was taken and intradermally injected into the upper part of the tail of Lewis rat to induce arthritis. After 10 days, the length of the ankle circumference of rats was measured, and then the rats were grouped and used in the experiment. Each compound was intraperitoneally injected twice a day. The clinical score, the length of the ankle circumference, and the weight were measured twice a week after the administration of the compounds. The clinical scores were assigned from 0 to 4 based on the thesis of Woods, etc. (J. Immunology, 1214-1222, 2001), and the total clinical score was determined by evaluating the feet of each rat and summing up the scores (normal: 0, most severe edema: 16). The length of the ankle circumference was calculated based on the formula of 2.times.3.14( (a2+b2/2)) after measuring top-bottom sides (a) of the foot and lateral sides (b) of the foot. The final value was determined by averaging the calculated values of each foot.

[1226] The results are shown in FIG. 5. In FIG. 5, (A) shows the experimental results of Compound 255, (B) shows the experimental results of Compound 374, and (C) shows the experimental results of Compound 461. In (A) of FIG. 5, the clinical store of the vehicle group was 4.9, and those of the experimental groups treated with Compound 255 in an amount of 3, 10, and 30 mg/kg twice a day were 3.0, 2.6, and 0.7, from which it can be seen that the arthritis symptoms were improved by 40 to 90%. In (B) of FIG. 5, the clinical store of the vehicle group was 8.1, and those of the experimental groups treated with Compound 374 in an amount of 3, 10, and 30 mg/kg twice a day were 2.5, 0.8, and 1.3, from which it can be seen that the arthritis symptoms were improved by 70 to 90%. In each experiment, the comparison of Compounds 255 and 374 with the control compound Tofacitinib reveals that they have an equivalent efficacy. In (C) of FIG. 5, the clinical store of the vehicle group was 4.2, and those of the experimental groups treated with Compound 461 in an amount of 25 and 50 mg/kg twice a day were 1.9 and 1.3, from which it can be seen that the arthritis symptoms were improved by more than 50 to 70%, which were higher than that of MTX used as the control group.

Example 172

Efficacy of Compound 254 and 255 in Colitis Models

[1227] The efficacy of the novel urea derivatives of the present invention on the treatment of colitis in colitis models was determined.

[1228] 3.0% dextran sulfate sodium (DSS: MP biomedicals) was dissolved in deionized water and supplied to 9-week-old C57BL/6J mice for 5 to 7 days and then water was normally supplied to the mice to induce colitis in animal models. The experimental animals were classified into a solvent control group and each group treated with Compound 254 and Compound 255 as test materials based on the body weight of the experimental animals. The test material was intraperitoneally injected twice a day after 8 days from the supply of DSS. The evaluation of the efficacy in colitis models was made by determining the degree to which the weight, lost due to the disease, was recovered to normal level, and the results are shown in FIG. 6.

[1229] As shown in FIG. 6, the weights of the disease-induced models were lost as 17.5 to 18 g and then recovered to 18.5 to 19.0 g by the administration of Compound 254 and 19 to 19.5 g by the administration of Compound 255, indicating that the efficacy was excellent. As a result, the efficacy of the novel urea derivatives on treatment of colitis was confirmed.

[1232] The acetylation of tubulin, histone H3 and Histone H4 on RPMI8226 cells (1.0.times.106 cells/well) derived from myeloma was determined in the same manner as the cell determination in Example 1.

[1233] The results are shown in FIGS. 1 and 2.

[1234] As shown in FIGS. 1 and 2, it was found that Compounds 255 and 374 have the efficacy on the treatment of multiple myeloma with excellent cell selectivity.

[1235] 2. Determination of Cell Viability

[1236] RPMI 8226 cells were seeded in 96-well U-bottom plate at 3.times.105 cells/ml in 180 .mu.l per well, and 20 .mu.l of test material was added to the plate. The cells were incubated in a 37.degree. C. humidified 5% CO2 incubator for 48 hours, and each 20 .mu.l of 5 mg/ml 2-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) solution dissolved in PBS was added and incubated again for 4 hours.

[1237] 3. Determination of Combination Index (CI) for Combination Treatment

[1238] For the quantitative analysis of drug interaction between the novel urea compounds of the present invention and Velcade (BOZ) well known as a therapeutic agent for multiple myeloma, the combination index (CI) of cell fractions on cytotoxicity caused by the drugs was calculated based on the dose-response curve of single and combination treatments. For the analysis of the interaction between two drugs, the CI was measured using Compusyn software (Combosyn Inc.) according to the method of Chou and Talalay (CompuSyn by Ting-Chao Chou and Nick Martin, 2005). The CI is the dose ratio of two anticancer agents treated with the dose of two anticancers at the point representing the equivalent cytotoxic effects. CI<1, CI=1, and CI>1 are interpreted as synergism, additivity, and antagonism, respectively.

[1239] The results are shown in Table 16 and FIG. 7.

TABLE-US-00017 TABLE 16 Analysis of Combination Index for Combination Treatment Compound BOZ 255 (.mu.M) (nM) CI (1) CI (2) CI (3) 1.0 10.0 0.416 0.518 0.417 1.0 5.0 0.469 0.679 0.475 1.0 2.5 0.940 1.146 0.998 0.5 10.0 0.491 0.529 0.428 0.5 5.0 0.751 0.789 0.727 0.5 2.5 1.120 1.115 1.087 0.25 10.0 0.482 0.309 0.417 0.25 5.0 0.560 0.710 0.737 0.25 2.5 1.182 1.034 1.068

[1240] As shown in Table 16 and FIG. 7, the efficacy of the combination of two drugs can be determined by the combination index (CI), and the combination effect is excellent when this index is not less than 1. In the case of Compound 255, the CI is not less than 1 in most doses, from which it can be seen that the combination effect is excellent.
