Histone deacetylase (HDAC) inhibition causes hyperacetylation of histones leading to differentiation, growth arrest and apoptosis of malignant cells, representing a new strategy in cancer therapy. Many of the known HDAC inhibitors (HDACi) that are in clinical trials possess a hydroxamic acid, that is a strong Zn2+ binding group, thereby inhibiting some of the class I and class II isoforms. Herein we
抑制组蛋白脱乙酰基酶(HDAC)会导致组蛋白过度乙酰化,从而导致分化,生长停滞和恶性细胞凋亡,这代表了癌症治疗的新策略。在临床试验中,许多已知的HDAC抑制剂(HDACi)具有异羟肟酸,它是一个强Zn 2+结合基团,从而抑制了一些I类和II类同工型。本文中,我们描述了鉴定具有一级羧酰胺部分作为锌结合基团的选择性I类HDAC抑制剂的鉴定。该HDACi对多种癌细胞系表现出良好的抗增殖活性,并在与伏立诺他相当的异种移植模型中显示出功效。
