The present invention relates to a novel class of substituted nicotinamides. 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.
本发明涉及一类新型的替代烟酰胺化合物。这些化合物可以抑制组蛋白去乙酰化酶,适用于选择性诱导终末分化,并阻止肿瘤细胞的生长和/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以肿瘤细胞增殖为特征的患者方面是有用的。本发明的化合物还可能在预防和治疗TRX介导的疾病方面有用,如自身免疫、过敏和炎症性疾病,以及预防和/或治疗中枢神经系统(CNS)疾病,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,以及这些药物组合物的安全用药方案,易于遵循,并在体内产生这些化合物的治疗有效量。
