The present application provides bifunctional compounds of Formula (I), or Targeting Ligand, 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)的双功能化合物,或者靶向
配体,或者其药学上可接受的盐、
水合物、溶剂合物、前药、立体异构体或互变异构体,这些化合物作为蛋白质降解诱导基团,用于细胞周期依赖性激酶4(CDK4)和/或细胞周期依赖性激酶6(CDK6)。本申请还涉及通过使用将泛素连接酶结合基团与能够结合到CDK4和/或CDK6的
配体相连接的双功能化合物来实现CDK4和/或CDK6的靶向降解的方法,该方法可用于治疗由CDK4和/或CDK6调节的疾病。
