CDK2 inhibitor 73 is primarily used in research and development for studying cell cycle regulation and cancer biology. It is a potent and selective inhibitor of cyclin-dependent kinase 2 (CDK2), a protein involved in controlling cell division. By inhibiting CDK2, this compound helps researchers understand the mechanisms of cell proliferation and the role of CDK2 in various cancers, particularly those driven by uncontrolled cell growth. It is also explored as a potential therapeutic agent in preclinical studies to evaluate its efficacy in targeting cancer cells. Additionally, CDK2 inhibitor 73 aids in identifying biomarkers and pathways associated with CDK2 activity, contributing to the development of targeted cancer therapies.
