APG-1387, a bivalent SMAC mimetic and an IAP antagonist, blocks the activity of IAPs family proteins (XIAP, cIAP-1, cIAP-2, and ML-IAP). APG-1387 induces degradation of cIAP-1 and XIAP proteins, as well as caspase-3 activation and PARP cleavage, which leads to apoptosis. APG-1387 can be used for the research of hepatocellular carcinoma, ovarian cancer, and nasopharyngeal carcinoma[1][2][3][4][5].
APG-1387 (0.02-20 μM; 24 h) induces rapid degradation of cIAPs in HepG2 and HCCLM3 cells[1].APG-1387 (2 μM; 24 h) enhances TNF-α- and TRAIL-mediated anti-cancer activities in HepG2 and HCCLM3 cells. APG-1387 sensitizes HepG2 and HCCLM3 cells to NK cell-mediated killing in vitro[1].
APG-1387 (20 mg/kg; i.p. every 3 days for 4 weeks) sensitizes HCCLM3 tumors toward NK cell-mediated killing in mice[1].APG-1387 (20 mg/kg; i.p. every 3 days for 4 weeks) monotherapy exhibits some degree of anti-tumor effect and is well tolerated in mice[1].
