and selective ortho-aminoanilide inhibitors of histone deacetylases (HDACs) 1 and 2 are described. Different kinetic and thermodynamic selectivity profiles were obtained by varying the moiety occupying an 11Å channel leading to the Zn(2+) catalytic pocket of HDACs 1 and 2, two paralogs with a high degree of structural similarity. The design of these novel inhibitors was informed by two ligand-bound
描述了一系列新型和选择性的组蛋白脱乙酰基酶(HDACs)1和2的邻氨基苯胺抑制剂的结构活性和结构动力学关系。通过改变占据HDAC 1和2的Zn(2+)催化口袋的11Å通道所占的部分来获得不同的动力学和热力学选择性分布图,这两个同系物具有高度的结构相似性。这些新型抑制剂的设计是由截短的hHDAC2的两个配体结合晶体结构所决定的。BRD4884和BRD7232对HDAC1对HDAC2具有动力学选择性。我们证明,HDAC抑制剂的结合动力学可以针对单个同工型进行调整,以调节靶标停留时间,同时保留功能活性并增加组蛋白H4K12和H3K9乙酰化,在主要的小鼠神经元细胞培养测定中。这些染色质修饰剂具有可调节的结合动力学特性,可用于定义靶标参与要求与HDAC在不同疾病应用中的药效学响应之间的关系。
