生物活性

SKLB06489 is a selective and orally active inhibitor of type I PRMT enzymes, with IC50 values of 64.55 nM (PRMT1), 4.21 nM (PRMT6), and 51.27 nM (PRMT8). SKLB06489 inhibits cell proliferation, colony formation, DNA replication, and DNA damage repair in cancer cells. SKLB06489 induces G0/G1-phase cell cycle arrest and apoptosis in cancer cells. SKLB06489 enhances intracellular cholesterol efflux via ABCA1 and ABCG1 upregulation, disrupts cholesterol metabolic homeostasis, and suppresses tumor growth in subcutaneous xenograft models. SKLB06489 can be used for the research of triple-negative breast cancer (TNBC)[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.
