This invention pertains to certain carbamic acid compounds of the formula (I), which inhibit HDAC (histone deacetylase) activity: wherein: J is a linking functional group and is independently:—O —C(═O)— or —C(═O)—O — or —C(═O)—; Cy is a cyclyl group and is independently: C3-20carbocyclyl, C3-20heterocyclyl, or C5-20aryl; and is optionally substituted; Q1 is a cyclyl leader group, and is independently a divalent bidentate group obtained by removing two hydrogen atoms from a ring carbon atom of a saturated monocyclic hydrocarbon having from 4 to 7 ring atoms, or by removing two hydrogen atoms from a ring carbon atom of saturated monocyclic heterocyclic compound having from 4 to 7 ring atoms including 1 nitrogen ring atom or 1 oxygen ring atom; and is optionally substituted; Q2 is an acid leader group, and is independently: C1-8alkylene; and is optionally substituted; or: Q2 is an acid leader group, and is independently: C5-20arylene; C5-20arylene-C1-7alkylene; C1-7alkylene-C5-20arylene; or C1-7alkylene-C5-20aryleneC1-7alkylene; and is optionally substituted; and pharmaceutically acceptable salts, solvates, amides, esters, ethers, chemically protected forms, and prodrugs thereof. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit HDAC,and in the treatment of conditions mediated by HDAC, cancer, proliferative conditions, psoriasis, etc.
本发明涉及一些具有以下化学式(I)的碳酰胺类化合物,其抑制HDAC(组蛋白去乙酰化酶)活性:
其中:J是连接功能基,独立地为:—O—C(═O)—或—C(═O)—O—或—C(═O)—;Cy是环烷基团,独立地为:C3-20碳环烷基、C3-20杂环烷基或C5-20芳基;并且可选择性地被取代;Q1是环烷基团,独立地为由饱和的单环烃类碳环原子上去除两个氢原子或由含有4至7个环原子的饱和单环杂环化合物的环碳原子上去除两个氢原子获得的二价双齿基团;并且可选择性地被取代;Q2是酸性基团,独立地为:C1-8烷基;并且可选择性地被取代;或:Q2是酸性基团,独立地为:C5-20芳基、C5-20芳基-C1-7烷基、C1-7烷基-C5-20芳基或C1-7烷基-C5-20芳基-C1-7烷基;并且可选择性地被取代;以及其药学上可接受的盐、溶剂化合物、酰胺、酯、醚、化学保护形式和前药。本发明还涉及包含这种化合物的制药组合物以及在体内外中使用这种化合物和组合物来抑制HDAC,并用于治疗由HDAC介导的疾病,如癌症、增生性疾病、牛皮癣等。
