and OH; These compounds can inhibit histone deacetylase and are suitable for use in selectively inducing termin differentiation, and arresting cell growth and/or apoptosis of neoplastic cells, thereby inhibiting proliferation of such cells. Thus, the compounds of the present invention are useful in treating a patient having a tumor characterized by proliferation of neoplastic cells. The compounds of the invention may also be useful in the prevention and treatment of TRX-mediated diseases, such as autoimmune, allergic and inflammatory diseases, and in the prevention and/or treatment of diseases of the central nervous system (CNS), such as neurodegenerative diseases. The present invention further provides pharmaceutical compositions comprising the compounds of the instant invention and safe dosing regimens of these pharmaceutical compositions, which are easy to follow, and which result in a therapeutically effective amount of these compounds in vivo.
本发明涉及一类新颖的取代螺环化合物,其结构式如下:I,其中A、B和D独立地选自CR12、NR1a、C(O)和O;E选自键、CR12、NR1a、C(O)和O;其中至少一个A、B、D或E为CR12;并且当A为O时,E不为O;G为CR12;R选自NH2和OH。这些化合物可以抑制组蛋白去乙酰化酶,并适用于在选择性诱导终止分化、阻止肿瘤细胞生长和/或凋亡,从而抑制这些细胞的增殖。因此,本发明的化合物在治疗具有肿瘤细胞增殖特征的患者中非常有用。本发明的化合物还可以用于预防和治疗TRX介导的疾病,例如自身免疫、过敏和炎症性疾病,以及中枢神经系统(CNS)疾病的预防和/或治疗,例如神经退行性疾病。本发明还提供了包含本发明化合物的药物组合物和这些药物组合物的安全剂量方案,易于遵循,并在体内产生治疗有效量的这些化合物。
