cdk-6/9-in-1

CDK6/9-IN-1 (compound 66) is a potent, orally administered dual inhibitor of CDK6 and CDK9, with IC50 values of 40.5 nM and 39.5 nM, respectively.

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.
