WD40 repeat and SOCS box containing 1 (WSB1) consists of seven WD40 repeat structural domains at the -terminal end and one SOCS box structural domain at the -terminal end. WSB1 promotes cancer progression by affecting the Von Hippel-Lindau tumor suppressor protein (pVHL) and upregulating hypoxia inducible factor-1 (HIF-1) target gene expression. However, the crystal structure of WSB1 has not been reported, which is not beneficial to the research on WSB1 inhibitors. Therefore, we focused on specific small molecule inhibitors of WSB1. This study applied virtual screening and molecular dynamics simulations; finally, 20 compounds were obtained. Among them, compound G490-0341 showed the best stable structure and was a promising composite for further development of WSB1 inhibitors.
含WD40重复序列和SOCS盒蛋白1(WSB1)在其N末端由七个WD40重复结构域组成,在其C末端由一个SOCS盒结构域组成。WSB1通过影响冯·希佩尔-林道肿瘤抑制蛋白(pVHL)并上调缺氧诱导因子-1(HIF-1)靶基因表达来促进癌症进展。然而,WSB1的晶体结构尚未见报道,这不利于对WSB1抑制剂的研究。因此,我们专注于WSB1的特异性小分子抑制剂。本研究应用虚拟筛选和分子动力学模拟;最终获得了20种化合物。其中,化合物G490-0341显示出最佳的稳定结构,是进一步开发WSB1抑制剂的有前景的化合物。
