E3 ubiquitin ligases are attractive targets in the ubiquitin–proteasome system, however, the development of small-molecule ligands has been rewarded with limited success. The von Hippel–Lindau protein (pVHL) is the substrate recognition subunit of the VHL E3 ligase that targets HIF-1α for degradation. We recently reported inhibitors of the pVHL:HIF-1α interaction, however they exhibited moderate potency
E3 泛素连接酶是泛素-蛋白酶体系统中有吸引力的靶标,然而,小分子配体的开发却取得了有限的成功。von Hippel-Lindau 蛋白 (pVHL) 是 VHL E3 连接酶的底物识别亚基,可靶向 HIF-1α 进行降解。我们最近报道了 pVHL:HIF-1α 相互作用的抑制剂,但它们表现出中等效力。在此,我们报告了由 X 射线晶体结构引导的具有纳摩尔结合亲和力的配体系列的设计和优化。
