The present application provides bifunctional compounds of Formula (I):
or a pharmaceutically acceptable salt, hydrate, solvate, prodrug, stereoisomer, or tautomer thereof, which act as protein degradation inducing moieties for cyclin-dependent kinase 4 (CDK4) and/or cyclin-dependent kinase 6 (CDK6). The present application also relates to methods for the targeted degradation of CDK4 and/or CDK6 through the use of the bifunctional compounds that link a ubiquitin ligase-binding moiety to a ligand that is capable of binding to CDK4 and/or CDK6 which can be utilized in the treatment of disorders modulated by CDK4 and/or CDK6.
本申请提供了式 (I) 的双官能化合物:
或其药学上可接受的盐、
水合物、溶媒、原药、立体异构体或同系物,它们可作为细胞周期蛋白依赖性激酶 4 (CDK4) 和/或细胞周期蛋白依赖性激酶 6 (CDK6) 的蛋白质降解诱导分子。本申请还涉及通过使用双功能化合物靶向降解 CDK4 和/或 CDK6 的方法,该双功能化合物将泛素连接酶结合分子与能够与 CDK4 和/或 CDK6 结合的
配体连接起来,可用于治疗受 CDK4 和/或 CDK6 调节的疾病。
