Abstract

Development of selective kinase inhibitors that target the ATP binding site continues to be a challenge largely due to similar binding pockets. Palbociclib is a cyclin-dependent kinase inhibitor that targets the ATP binding site of CDK4 and CDK6 with similar potency. The enzymatic function associated with the kinase can be effectively probed using kinase inhibitors however the kinase-independent functions cannot. Herein, we report a palbociclib based PROTAC that selectively degrades CDK6 while sparing the homolog CDK4. We used competition studies to characterize the binding and mechanism of CDK6 degradation.<br /> (Copyright © 2019 Elsevier Ltd. All rights reserved.)
