cdk-4/6-in-2

CDK4 6-IN-2 is a potent inhibitor of CDK4 and CDK6 [IC50s: 2.7 and 16 nM].

LSN3106729 hydrochloride, the metabolite of Abemaciclib , is a CDK inhibitor with antitumor activity. LSN3106729 hydrochloride and a CRBN ligand have been used to design PROTAC CDK4 6 degrader[1].

CDK4 6-IN-14 is a potent, highly selective inhibitor of Cyclin-Dependent Kinases 4 and 6 (CDK4 6), with inhibition concentrations (IC50s) of 10 nM and 16 nM, respectively. It shows over 60-fold selectivity for CDK4 6 compared to CDKs 1, 2, 7, and 9, and exhibits significant selectivity against 205 other kinases.
