    Samuraciclib purchased from MCE. Usage Cited in: J Cancer Res Clin Oncol. 2022 Nov 18.  [Abstract]

    Colony-formation assay. Samuraciclib (5, 10, 20, 50, 100 nM; 7 days) signifcantly inhibits the colony-formation ability of the two CRPC models (C4-2 and 22RV1).

    生物活性

    Samuraciclib (CT7001) is a potent, selective, ATP-competitive and orally active CDK7 inhibitor, with an IC50 of 41 nM. Samuraciclib displays 45-, 15-, 230- and 30-fold selectivity over CDK1, CDK2 (IC50 of 578 nM), CDK5 and CDK9, respectively. Samuraciclib inhibits the growth of breast cancer cell lines with GI50 values between 0.2-0.3 µM. Samuraciclib has anti-tumor effects[1][2].

    Samuraciclib (ICEC0942; 0-10 µM; 24 hours; HCT116 cells) treatment promotes cell apoptosis[1].
    Samuraciclib (ICEC0942; 0-10 µM; 24 hours; HCT116 cells) treatment induces cell cycle arrest[1].
    Samuraciclib (ICEC0942; 0-10 µM; 0-24 hours; HCT116 cells) treatment inhibits the phosphorylation of PolII CTD in a dose and time dependent manner in HCT116 colon cancer cells. Samuraciclib also inhibits phosphorylation of CDK1, CDK2 and retinoblastoma[1].
    Samuraciclib (ICEC0942) inhibits the growth of MCF7, T47D, MDA-MB-231, HS578T, MDA-MB-468, MCF10A and HMEC cells with GI50 values of 0.18 µM, 0.32 µM, 0. 33 µM, 0.21 µM, 0.22 µM, 0.67 µM and 1.25 µM, respectively[1].

    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.
