Tozasertib (VX-680, MK-0457, VX6) (Cat No.:I004416) is a potent small molecule inhibitor of multiple protein kinases, including Aurora kinases A, B, and C. It disrupts the function of these kinases, which are involved in regulating cell division and mitosis. By inhibiting Aurora kinases, tozasertib interferes with the proper alignment and segregation of chromosomes during cell division, leading to cell cycle arrest and cell death. Tozasertib has demonstrated promising anti-tumor activity in preclinical studies and has been investigated in clinical trials for the treatment of various cancers, including hematological malignancies and solid tumors.
