  靶向靶向嵌合体降解蛋白的CDK6的潜在和优先降解。

  摘要：

  开发了劫持癌症治疗靶标CDK6的重点PROTAC文库。为理解这些PROTAC中的降解曲线差异，提出了一种设计原则，即“匹配/不匹配”。值得注意的是，通过将CDK6抑制剂palbociclib和E3连接酶CRBN募集者pomalidomide连接起来，可产生具有特定且显着的CDK6降解潜能的强效PROTAC。PROTAC强烈抑制包括多发性骨髓瘤在内的造血癌细胞的增殖，并强烈抑制CDK6的拷贝扩增/突变形式的降解，这表明了其未来的潜在临床应用。

  A focused PROTAC library hijacking cancer therapeutic target CDK6 was developed. A design principle as "match/mismatch" was proposed for understanding the degradation profile differences in these PROTACs. Notably, potent PROTACs with specific and remarkable CDK6 degradation potential were generated by linking CDK6 inhibitor palbociclib and E3 ligase CRBN recruiter pomalidomide. The PROTAC strongly inhibited
