Description
本发明涉及(1-氧代-1,2,3,4-四氢化萘-2-基)-链烷酸羟基酰胺,或其药物可接受盐。已经发现这些化合物具有抗细胞增殖活性,例如抗癌活性,因此在人或动物体的治疗方法中有用。本发明还涉及所述(1-氧代-1,2,3,4-四氢化萘-2-基)-链烷酸羟基酰胺的制备方法,含有所述化合物的药物组合物,以及所述化合物在制备用于在温血动物例如人中产生抗细胞增殖作用的药物中的应用。
发明背景
转录调控是细胞分化、增殖、和凋亡中的主要事件。一组基因转录的激活决定了细胞的目标,基于此,转录被多种因子严密调控。涉及该过程的调节机制中的一种是DNA三级结构的改变,它是通过调节转录因子到其目的DNA片段的可达性而影响转录。核心组蛋白的乙酰化状况调节核小体的完整性。在低乙酰化状态,核小体紧密堆积,因此无法转录。另一方面,随着核心组蛋白的乙酰化,核小体变得松散,导致转录得以进行。组蛋白的乙酰化状况由组蛋白乙酰转移酶(HAT)和组蛋白脱乙酰酶(HDAC)之间活性的平衡来控制。最近,发现HDAC抑制剂阻止几种类型的癌细胞的生长和凋亡,包括结肠癌、T-细胞淋巴瘤、和红白血病细胞。假设细胞凋亡是癌症进展的关键因素,HDAC抑制剂有希望成为癌症治疗中的细胞凋亡的有效诱导剂。
几种结构类型的HDAC抑制剂在现有技术中已有报道,Marks,P.M.,等,J.Natl.Cancer Inst.15(2000)1210-1216作了综述。WO 98/55449和U.S.Pat.No.5,369,108中也公开了具有HDAC抑制活性的异羟肟酸化合物。
已发现(1-氧代-1,2,3,4-四氢化萘-2-基)-链烷酸羟基酰胺基于其HDAC抑制活性而具有抗细胞增殖性质。本申请描述的几种(1-氧代-1,2,3,4-四氢化萘-2-基)-链烷酸羟基酰胺的HDAC抑制活性优于SAHA(辛二酰基苯胺异羟肟酸,已经表明其具有HDAC抑制活性(U.S.Pat.No.5,369,108)。
