concerns the synthesis of new histone deacetylase inhibitors (HDACi) characterized by a 1,4-benzodiazepine ring used as the cap, joined through an amide function or a triple bond as connection units, to a linear alkyl chain bearing the hydroxamate function as Zn2+-chelating group. Biological tests performed in human acute promyelocytic leukemia NB4 cells showed that new hybrids can induce histone H3/H4
这项研究涉及新的组蛋白脱乙酰基酶抑制剂(HDACi)的合成,其特征是将1,4-苯并二氮杂环用作帽,通过酰胺功能或三键作为连接单元连接到带有异羟肟酸酯功能的线性烷基链上。 Zn2 +-螯合基团。在人类急性早幼粒细胞白血病NB4细胞中进行的生物学测试表明,新的杂种可以诱导组蛋白H3 / H4乙酰化,生长停滞以及细胞凋亡。值得注意的是,手性化合物表现出立体选择性活性。
