Description

Benzamide histone deacetylase enzyme inhibitors and medicinal preparations thereof with differentiation and antiproliferative activity
Technical field
The present invention relates to have brand-new micromolecular compound synthetic of therapeutic action and in treatment and differentiation and the clinical application of breeding aspect the relevant disease
Background technology
Abnormal gene expression plays an important role in the pathogeny of numerous disease, and these diseases comprise tumour, endocrine regulation, disease of immune system, inherited disease and nervous system disorders.People's genome exists with DNA, histone and the nonhistones chromatin Structure that is packaged into, and chromatin Structure is determining a specific gene plays an important role when whether expressing.Generally speaking, spissated chromatin suppresses to transcribe, and the gene of transcriptionally active often is arranged in open chromatin.
Forming chromatinic basic repeating unit nucleosome is made of round the histone core that contains 4 kinds of histones the dna double chain.This histone core comprises a H3-H4 tetramer and two H2A-H2B dimers.Histone h1 is attached to the connection portion between nucleosome, and by it be rich in the C-terminal of positive electricity nuclear and the negative charge on the DNA chain to keep the stability of chromatin Structure.The structure of this high-sequential of nucleosome has determined that chromatin is formed and relation (the Ricky W.Johnstone of gene activation, " Histone deacetylase inhibitors:noveldrugs for the treatment of cancer ", Nature Reviews Drug Discovery 2002,1:287).The histone N-terminal can be translated the back and modify, and therefore can change STRUCTURE OF CHROMATIN and function.Wherein a kind of modification is reversible acetylize of histone afterbody lysine residue and deacetylation.The acetylation of histone level be by the acetylation of histone enzyme (Histoneacetylases, HATs) and histon deacetylase (HDAC) (Histone deacetylases, HDACs) common control.The histone N-terminal is modified except being acetylation, can also be by phosphorylation, methylate and the ADP-ribosylation.These modify influence histone electrically and function, and then change STRUCTURE OF CHROMATIN and genetic expression (Current Opinion in Oncology2001,13:477-483).
Research has in recent years disclosed being closely connected between acetylation of histone and chromatin reconstitution and gene regulating.A lot of transcriptional activator complex bodys all have intrinsic acetylation of histone enzymic activity, on the contrary, transcribe and suppress complex body and then have and recruit histon deacetylase (HDAC) (Bioassays 1998,20:615) to the activity of target gene promotor.Some specific transcriptional incitants, as nuclear receptor superfamily, cAMP effector conjugated protein (CREB), signal conduction transcriptional factors 1 (STAT-1) wait can be with various auxilliary activation sub and co-repressor selectively acting in different tissues and gene, constituted the regulated and control network of gene Selection expression.These regulated and control networks are being controlled the balance of our physical function, disturb these networks will cause disease or influence the process of disease.Therefore, regulate these transcription complex interaction between protein and provide new method (E.Korzus for treatment tumour, endocrine regulation, disease of immune system, inherited disease and nervous system disorders, Transcription Factor-specific Requirements for Coactivatorand Their Acetyltransferase Functions.Science 1998,279:703-707; N.J.McKenna and B.W.O ' Malley, Combinatorial Control of GeneExpression by Nuclear Receptors and Coregulators.Cell 2002,108 (4): 465-474; M.J.Pazin and J.T.Kadonaga, What ' s Up and Downwith Histone Deacetylation and Transcription? Cell 1997,89 (3): 325-328; H.Zhong, R.E.Voll and S.Ghosh, Phosphorylation of NF-B p65 byPKA Stimulates Transcriptional Activity by Promoting a Novel BivaleInteraction with the Coactivator CBP/p300.Molecular Cell 1998,1 (5): 661-671; J.S.Steffan, Histone deacetylase inhibitors arrestpolyglutamine-dependent neurodegeneration in Drosophila, Nature 2001,413:691-694; US20020115716 Λ 1, WO0056153 Λ 1).
For instance, cells whose development and differentiation are subjected to the regulation and control that gene program is expressed, and this is the regulation and control on the chromatin Structure level.Heritable variation or sudden change cause constitutive activation oncogene such as RAS, perhaps make the suppressor gene inactivation such as the p53 of tumour, all will influence to comprise a series of minutes subprocess of transcribing.In addition; some cause the heritable variation of acetylation of histone enzyme and the unusual effect of deacetylase; as their target gene is misplaced; or make acetylation of histone enzyme functionally inactive; or overexpression histon deacetylase (HDAC) etc. all can be broken the process of cell normal development and differentiation; cause the generation and the development (Current Opinion Genet.Development 1999,9:40-48 and 175-184) of tumour.Some human tumors produce relevant with the imbalance of deacetylation enzymic activity with the acetylation of histone enzyme; one of them example is in people's acute myelocytic leukemia patient; common to 15 and No. 17 chromosomal dystopys, the ectopic result can produce the fusion rotein of a kind of RAR of comprising α, PML and three kinds of protein moleculars of PLZF.This unusual fusion rotein can combine with the cis-acting elements of RAR; and by recruiting the histon deacetylase (HDAC) that high-affinity is arranged with powerful combination of SMRT co-repressor; make the target gene expression of RAR be subjected to lasting inhibition; and (Oncogene 2001,20:7204-7215) to have lost reaction to retinoic acid.Retinoic acid acceptor (RAR) is a kind of dependence part activated transcription factor, and it has important effect to the differentiation of marrow.The heterodimer that RAR and RXR constitute can be incorporated on the retinoic acid response element of target gene promoter region.When being deficient in vitamin A acid, RAR/RXR can recruit SIN/HDAC by co-repressor NCOR and SMRT and suppress to transcribe; And after adding part, HDAC is released, and RAR/RXR can have the active cofactor combination of HAT and activated transcription with TIF2, CBP etc. immediately.Therefore, activate or the differentiation that suppresses to contain the gene pairs medullary cell of retinoic acid response element plays a very important role.And the inhibitor that adds HDAC can make acute myeloid leukemia cell recover retinoic acid is induced the ability of differentiation, hints that unusual dna methylase inhibitor is a key factor of leukemia pathogenic process.
Existing report shows, can suppress the expression of some cancer suppressor genes when the histon deacetylase (HDAC) overexpression, as p53.P53 is a crucial regulation and control person of cell proliferation, it signal can be passed to control the cell cycle gene, and when ambient pressure exists cell death inducing.The realization of p53 function is that mainly it can be directly combines and activated transcription with special dna sequence dna, if undergo mutation and make functionally inactive in its DNA land, then regular meeting causes cancer.Evidence suggests that CBP/p300 can raise p53 (W.Gu and R.G.Roeder by making histone and p53 acetylize; Activation of p53 Sequence-Specific DNA Bindingby Acetylation of the p53 C-Terminal Domain.Cell 1997,90 (4): 595-606.).On the contrary; the intravital HDAC-1 of Mammals, HDAC-2 and HDAC-3 can reduce p53 (L.-J.Juan by making histone and p53 deacetylation; et al.; Histone Deacetylases Specifically Down-regulate p53-dependent GeneActivation.The Journal of Biological Chemistry 2000,275 (27): 20436-20443).
Above-mentioned experiment shows that the improper transcripting suppressioning action that is mediated by HDACs can change STRUCTURE OF CHROMATIN, disturbs normal cytodifferentiation, causes the generation of tumour and other proliferative disease.Therefore, the activity of inhibition HDAC may be the effective ways of treatment tumour and other proliferative disease.
Had been found that the inhibitor of several histone deacetylases, comprised (1) short chain fatty acid, as butyric acid and benzenebutanoic acid; (2) organic hydroxamic acid is as suberoylanilidehydroxamic acid (SAHA) and trichostatin A (TSA); (3) contain 2-amino-8-oxygen-9, the cyclic tetrapeptide of 10-epoxy decanoyl is as trapoxin and HC-toxon; (4) do not contain 2-amino-8-oxygen-9, the cyclic tetrapeptide of 10-epoxy decanoyl is as Apicidin and FK228; (5) benzamide compound is as MS-275 (EP0847992A1, US2002/0103192A1, WO 02/26696 Λ 1, WO 01/70675 Λ 2, WO 01/18171 Λ 2).
Butyric acid is as a kind of inhibitor of cell proliferation and the inductor of cytodifferentiation; its activity mainly comes from inhibition (the A.Nudelman and A.Rephaeli to histon deacetylase (HDAC); Novel Mutual Prodrug of Retinoic and Butyric Acids with EnhancedAnticancer Activity.J.Med.Chem.2000,43 (15): 2962-2966.).Benzenebutanoic acid can be used for treating separately diseases such as thalassemia, tokoplasmosis, malaria, also can with retinoic acid combination therapy acute myelocytic leukemia (R.P.Warrcll.ct al., Therapeutictargeting of transcription in acute promyelocytic leukemia by use of aninhibitor of histone deacetylase.J.Natl.Cancer Inst.1998,90 (21): 1621-1625.).Valproic acid is an anticonvulsant drug, also be found to be (the C.J.Phiel et. that works by direct inhibition of histone deacetylase, Histone Deacetylase Is aDirect Target of Valproic Acid, a Potent Anticonvulsant, Mood Stabilizer, and Teratogen.The Journal of Biological Chemistry 2001,276 (39): 36734-36741; EP1170008A1).
Some benzamide compounds just have the NSC 630176 activity under lower micromolar concentrations.Wherein the lead compound MS-275 of Mitsui Chemicals company development is that first is proved to be the NSC 630176 that has oral antitumour activity in animal body, and there is not severe side effect (A.Saito et al., A syntheticinhibitor of histone deacetylase, MS-27-275, with marked in vivoantitumor activity against human tumors.Proceedings of the NationalAcademy of Sciences of the United States of America 1999,96 (8): 4592-4597; EP 0847992 A1).At present, MS-275 just carries out leukemic clinical study in the Grccncbaum of University of Maryland Cancer center, carry out clinical study (E.B.Levit, Clinical Trials in Leukemiafocus on New Treatment Approaches.2001 Release-University ofMaryland Medical News 2001 Maryland of solid tumor simultaneously in American National cancer research institute Http:// www.umm.edu/news/ Releases/karp.html, A Phase I Study of an Oral Histone DeacetylaseInhibitor, MS-275, in Refractory Solid Tumors and Lymphomas.2001, National Cancer Institute).Yet the compound that better performance is arranged that some are new still awaits exploitation, so that can obtain the medicine that stronger HDAC suppresses active and lower side effect.
