Description: Verubulin, also known as MPC-6827, is a quinazoline derivative with potential dual antineoplastic activities. Verubulin binds to and inhibits tubulin polymerization and interrupts microtubule formation, resulting in disruption of mitotic spindle assembly, cell cycle arrest in the G2/M phase, and cell death. MPC-6827 appears to disrupt tumor microvasculature specifically, which may result in acute ischemia and massive tumor cell death.
