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].
