The present invention relates to a novel class of substituted spirocyclic compounds. These compounds can inhibit histone deacetylase and are suitable for use in selectively inducing terminal 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.
本发明涉及一种新型的取代
螺环化合物。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末端分化、阻止肿瘤细胞的增殖和/或凋亡,从而抑制这些细胞的增殖中使用。因此,本发明的化合物可用于治疗具有肿瘤细胞增殖特征的患者。本发明的化合物还可用于预防和治疗TRX介导的疾病,例如自身免疫性、过敏性和炎症性疾病,并用于预防和/或治疗中枢神经系统(CNS)疾病,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,这些方案易于遵循,并在体内产生治疗有效量的这些化合物。
