reported. PROTACs are a novel class of small-molecules that offer the potential for differentiated pharmacology compared to traditional inhibitors by redirecting the cellular ubiquitin-proteasome system to degrade target proteins of interest. We report here the preparation of palbociclib-based PROTACs that incorporate binders for three different E3 ligases, including a novel IAP-binder, which effectively
CDK4和CDK6
抑制剂已成为FDA批准的针对乳腺癌患者的重要治疗选择。CDK4 / 6
抑制剂药物的特性和药理作用已得到广泛介绍,并且还报道了通过PROTAC策略对这些靶标降解的研究。PROTAC是一类新型的小分子,与传统的
抑制剂相比,可通过改变细胞泛素-
蛋白酶体系统的方向来降解目标靶标蛋白,从而为药理差异化提供潜力。我们在这里报告了基于palbociclib的PROTAC的制备,其中结合了三种不同的E3连接酶(包括新型IAP粘合剂)的粘合剂,该粘合剂可有效降解细胞中的CDK4和CDK6。此外,
