Antiproliferative agent-57 (compound M2) is a tumor angiogenesis inhibitor. Antiproliferative agent-57 inhibits the secretion of VEGF in SiHa cells under hypoxic conditions (IC50=0.68 µM) without inducing cytotoxicity. Antiproliferative agent-57 can modulate the PI3K/AKT/mTOR and MAPK signaling pathways in tumor cells to inhibit the expression of HIF-1alpha and VEGF in tumor tissues[1].
