Vinblastine is M phase specific. It binds to microtubular proteins and arrests mitosis at the metaphase by disrupting mitotic spindle formation. It blocks glutamic acid utilization, thus inhibiting purine synthesis, the citric acid cycle, and the formation of urea. It may also interfere with nucleic acid and protein synthesis.
