Biological Information

  • Product Name
    Senexin B
  • Note
    Research use only, not for human use.
  • Brief Description
    Senexin B (SNX2-1-165) is a highly potent, selective and orally available CDK8/CDK19 inhibitor with IC50 of 24-50 nM.
  • Description
    Senexin B (SNX2-1-165) is a highly potent, selective and orally available CDK8/CDK19 inhibitor with IC50 of 24-50 nM; exhibits selectivity for CDK8 and CDK19 with Kd of 140 nM and 80 nM, respectively; significantly suppresses tumor growth in ER-positive breast cancer xenografts.
  • In Vitro
    Senexin B inhibits CDK8/19 in low nanomolar range. Senexin B is a newly optimized derivative of Senexin A. It has the same high selectivity for CDK8/19 and is more potent than Senexin A. Senexin B strongly reduces the emergence of estrogen independent cells. Senexin B shows synergy with fulvestrant in MCF7, T47D-ER/Luc and BT474.
  • In Vivo
    Pretreatment of tumor-free mice with Senexin B significantly inhibits the growth of triple-negative breast cancer (TNBC) cells inoculated into mice subsequently to Senexin B administration, indicating a general chemopreventive effect on the normal tissue “soil”. Senexin B potentiates the tumor-suppressive effect of doxorubicin on established TNBC xenografts; this effect is associated with the suppression of NFκB-mediated transcriptional induction of tumor-promoting cytokines. Senexin B inhibits invasive growth into the muscle layer in an orthotopic xenograft model of MDA-MB-468 TNBC cells. In a spleen-to-liver colon cancer metastasis model of syngeneic mouse CT26 tumors, Senexin B treatment of mice have the same effect as CDK8 knockdown in tumor cells: suppression of metastatic growth in the liver without a significant effect on primary tumor growth in the spleen. Senexin B suppresses tumor growth and augmentes the effects of fulvestrant in ER-positive breast cancer xenografts.
