Previously, we reported a click-chemistry based approach to the synthesis of a novel class of histone deacetylase (HDAC) inhibitors [1]. The lead compound NSC746457 was found to be as potent as SAHA (Vorinostat). Further optimization of NSC746457 by using the HDAC2-TSA crystal structure is described herein. Docking of NSC746457 into HDAC2 binding domain suggested that the hydrophobic residue Phe210 flanking
以前,我们报道了一种基于点击化学的方法来合成一类新型的组蛋白脱乙酰基酶(HDAC)抑制剂[1]。发现前导化合物NSC746457与SAHA(伏立诺他州)一样有效。本文描述了通过使用HDAC2-TSA晶体结构对NSC746457进行的进一步优化。将NSC746457对接至HDAC2结合域表明,可以利用帽基结合基序侧翼的疏水残基Phe210进行结构优化。肉桂酸帽区域的亚甲基取代导致鉴定出更有效的HDAC抑制剂:异丙基衍生物5和叔丁基衍生物6,其IC 50值分别为22 nM和18 nM。
