The discovery and optimization of a novel series of G9a/GLP (EHMT2/1) inhibitors are described. Starting from known G9a/GLP inhibitor 5, efforts to explore the structure-activity relationship and optimize drug properties led to a novel compound 13, the side chain of which was converted to tetrahydroazepine. Compound 13 showed increased G9a/GLP inhibitory activity compared with compound 5. In addition
描述了新型G9a / GLP(EHMT2 / 1)抑制剂的发现和优化。从已知的G9a / GLP抑制剂5开始,探索结构-活性关系并优化药物性质的努力导致了新化合物13的侧链转化为四氢a庚因。与化合物5相比,化合物13显示出增加的G9a / GLP抑制活性。另外,化合物13表现出改善的人类ether-A-go-go相关基因(hERG的)的抑制活性比化合物5和也改善小鼠的药物动力学曲线(口服利用度:17%至40%)。最后,G9a与化合物13的共晶体结构 为进一步开发基于四氢a庚因的G9a / GLP抑制剂提供了基础。
