    • 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.
    • 本发明涉及一类具有至少两个含芳基基团的异羟肟酸衍生物,其中至少一个是喹啉基,异喹啉基或苄基部分,通过亚甲基链与异羟肟酸基团连接。 异羟肟酸化合物可用于治疗癌症,例如脑癌。 异羟肟酸化合物也可以抑制组蛋白脱乙酰酶,适用于选择性诱导终末分化,阻止肿瘤细胞的细胞生长和/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以肿瘤细胞增殖为特征的肿瘤的患者。 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,过敏性和炎性疾病,以及预防和/或治疗中枢神经系统(CNS)的疾病,例如神经变性 疾病
