    Description

    Cirtociclib (BLU-222) is an orally active and highly selective CDK2 inhibitor. Cirtociclib disrupts Rb signaling and causes G1 arrest and apoptosis in CCNE1-amplified endometrial cancer cells[1][2][3].

    In Vitro

    Cirtociclib (BLU-222) (25-250 nM; 0-288 h) exhibits antiproliferative activity against KLE and HEC-1-B cell lines[2].

    MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
