G protein-coupled receptor (GPCR) kinases (GRKs) regulate the desensitization and internalization of GPCRs. Two of these, GRK2 and GRK5, are upregulated in heart failure and are promising targets for heart failure treatment. Although there have been several reports of potent and selective inhibitors of GRK2 there are few for GRK5. Herein, we describe a ligand docking approach utilizing the crystal
G蛋白偶联受体(GPCR)激酶(GRKs)调节GPCR的脱敏和内在化。其中两个GRK2和GRK5在心力衰竭中被上调,并有望成为心力衰竭治疗的靶标。尽管有几篇关于GRK2的有效和选择性抑制剂的报道,但关于GRK5的报道却很少。在本文中,我们描述了利用GRK2-Gβγ·GSK180736A和GRK5·CCG215022配合物的晶体结构进行配体对接的方法,以寻找预计可赋予GRK2和/或GRK5效力和选择性的酰胺取代基。通过这项活动,我们成功地产生了两种新的强效GRK5抑制剂,尽管它们都没有表现出对GRK2的选择性。
