The CDK8–cyclinCcomplex is an important anti-tumor target, but unlike CDK8, cyclin C remains undruggable. Modulators regulating cyclin C activity directly are still under development. Here, a series of hydrophobic tagging-based degraders of the CDK8–cyclinCcomplex were designed, synthesized, and evaluated to identify the first dual degrader, LL-K8-22, which induced selective and synchronous degradation
CDK8-细胞周期蛋白 C 复合物是重要的抗肿瘤靶点,但与 CDK8 不同,细胞周期蛋白 C 仍然不可成药。直接调节细胞周期蛋白 C 活性的调节剂仍在开发中。在这里,设计、合成和评估了一系列基于疏水标记的 CDK8-细胞周期蛋白 C 复合物降解剂,以确定第一个双降解剂LL-K8-22 ,它诱导 CDK8 和细胞周期蛋白 C 的选择性和同步降解。免疫印迹研究表明, LL-K8-22显着降解 CDK8,而不降低 CDK19,并且不降解除细胞周期蛋白 C 之外的其他细胞周期蛋白。此外, LL-K8-22比其亲本分子BI-1347表现出增强的抗增殖作用, MDA-MB-468 细胞中的效力增加了 5 倍。 LL-K8-22对 CDK8-细胞周期蛋白 C 下游信号传导的影响比BI-1347更显着,更持久地抑制 STAT1 磷酸化。 RNA 测序分析表明, LL-K8-22抑制 E2F 和 MYC 驱动的致癌转录程序。总体而言,
