acetyl histone H3 in a dose-dependent manner, which is similar to the behavior of suberoylanilide hydroxamic acid (SAHA). Molecular docking study revealed that the conformation of 7m' in the active site of HDAC2 was similar to positive drug SAHA, which were oriented with the hydroxamic acid towards the catalytic center and formed metal binding with zinc ion.
设计,合成和筛选了含有嘌呤支架的新型异羟肟酸酯作为组蛋白脱乙酰基酶(HDAC)抑制剂的生物学活性。其中一些表现出优异的acti-HDACs活性和抗增殖活性,最有希望的化合物是7m'。Western印迹分析表明,化合物7f',7l',7m',7o'可以增加HCT116和K562细胞株中组蛋白H3的乙酰化水平,而7m'则以剂量依赖的方式增加乙酰基组蛋白H3的水平,这相似异戊酰苯胺异羟肟酸(SAHA)的行为。分子对接研究表明,HDAC2活性位点中的7m'构象与阳性药物SAHA相似,后者被异羟肟酸定向至催化中心,并与锌离子形成金属结合。
