The present invention is directed to prodrugs of hydroxamic acid based histone deacetylase (HDAC) inhibitors, e.g., suberoylanilide hydroxamic acid (SAHA). The prodrugs are acylated derivatives having increased aqueous solubility and cellular permeability as compared with the free hydroxamic acid, and are useful for inhibiting HDACs, and for selectively inducing terminal differentiation, cell growth arrest and/or apoptosis of neoplastic cells, thereby inhibiting proliferation of such cells. Thus, the prodrugs of the present invention are useful in treating a patient having a tumor characterized by proliferation of neoplastic cells. The prodrugs of the invention are also useful in the prevention and treatment of thioredoxin (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.
本发明涉及羟基酰胺基的组蛋白去乙酰化酶(HDAC)抑制剂的前药,例如亚麻酰苯胺羟基酸(SAHA)。这些前药是酰化衍生物,与自由羟基酸相比具有增加的水溶性和细胞渗透性,并且可用于抑制HDAC,有选择地诱导肿瘤细胞的终末分化、细胞生长停滞和/或凋亡,从而抑制这些细胞的增殖。因此,本发明的前药可用于治疗具有肿瘤细胞增殖特征的患者。本发明的前药也可用于预防和治疗硫氧还蛋白(TRX)介导的疾病,例如自身免疫性、过敏性和炎症性疾病,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。
