Histone deacetylase is a metallo-enzyme with zinc at the active site. Compounds having a zinc-binding moiety, for example, an alpha-ketoepoxide group, such as an alpha-ketothio group, can inhibit histone deacetylase. Histone deacetylase inhibition can repress gene expression, including expression of genes related to tumor suppression. Accordingly, inhibition of histone deacetylase can provide an alternate route for treating cancer, hematological disorders, e.g., hemoglobinopathies, autosomal dominant disorders, e.g. spinal muscular atrophy and Huntington's disease, genetic related metabolic disorders, e.g., cystic fibrosis and adrenoleukodystrophy, or to stimulate hematopoietic cells ex vivo.
组蛋白去乙酰化酶是一种含锌活性位点的金属酶。具有结合锌的基团的化合物,例如α-酮酰环氧基团,如α-酮硫基团,可以抑制组蛋白去乙酰化酶。组蛋白去乙酰化酶抑制可以抑制基因表达,包括与肿瘤抑制相关的基因表达。因此,抑制组蛋白去乙酰化酶可以提供一种替代途径用于治疗癌症、血液学疾病,例如血红蛋白病、常染色体显性疾病,例如脊髓肌萎缩症和亨廷顿病,遗传相关代谢性疾病,例如囊性纤维化和肾上腺白质病,或刺激外体造血细胞。
