The present invention relates to a novel class of hydroxamic acid derivatives having at least two aryl containing groups, at least one of which is a quinolinyl, isoquinolinyl or benzyl moiety, linked to the hydroxamic acid group through a methylene chain. The hydroxamic acid compounds can be used to treat cancer, for example, brain cancer. The hydroxamic acid compounds can also 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 are useful in treating a patient having a tumor characterized by proliferation of neoplastic cells. The compounds of the invention are also 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.
本发明涉及一种新型的羟肟酸衍生物类,其至少具有两个含芳基团的基团,其中至少一个是喹啉基团、异喹啉基团或苄基团,通过亚甲基链与羟肟酸基团连接。这些羟肟酸化合物可用于治疗癌症,例如,脑癌。这些羟肟酸化合物还可以抑制组蛋白去乙酰化酶,并适用于选择性诱导终末分化,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、过敏和炎症性疾病,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。
