CDK4-IN-3

CDK4-IN-3 (Compound 389) is a highly selective irreversible inhibitor of cyclin-dependent kinase 4 (CDK4) with an IC50 of 25 nM and exhibits more than 10-fold selectivity over CDK6. It arrests the cell cycle at the G1 phase and induces apoptosis in tumor cells. CDK4-IN-3 holds potential for research in solid tumors such as breast and lung cancer.
