SP-6-27 is a tubulin depolymerizing agent that binds to the colchicine site of beta-tubulin. SP-6-27 induces G2/M cell cycle arrest in ovarian cancer cells. SP-6-27 enhances intrinsic apoptosis in ovarian cancer cells through upregulation of Bax, Apaf-1, caspase-6, caspase-9, and caspase-3. SP-6-27 reduces ovarian cancer cell migration. SP-6-27 inhibits capillary tube formation by human umbilical vein endothelial cells. SP-6-27 shows minimum cytotoxicity to normal ovarian epithelia. SP-6-27 shows enhanced cytotoxicity in chemo-sensitive/resistant ovarian cancer cells when combined with Cisplatin (HY-17394). SP-6-27 can be used for the research of ovarian cancer[1].
