制备了一系列酰胺基丙烯基异羟肟酸衍生物,作为人类组蛋白脱乙酰基酶(HDAC)的新型抑制剂。在HDAC抑制试验中,几种化合物在<100 n M时表现出效价,亚微摩尔IC 50在针对三种肿瘤细胞系的测试中获得了最佳值,并观察到了人类和小鼠微粒体的显着稳定性。选择了三种代表性化合物进行进一步表征,并针对一系列I类和II类HDAC进行了选择性分析,并进行了初步的体内药代动力学(PK)实验。尽管它们具有很高的微粒体稳定性,但它们在体内PK研究以及大鼠和人类肝细胞中均显示出中到高的清除率,这表明非微粒体酶催化了主要的代谢途径。

A series of amidopropenyl hydroxamic acid derivatives were prepared as novel inhibitors of human histone deacetylases (HDACs). Several compounds showed potency at <100 nM in the HDAC inhibition assays, sub‐micromolar IC50 values in tests against three tumor cell lines, and remarkable stability in human and mouse microsomes was observed. Three representative compounds were selected for further characterization
