It is a vinblastine derivative with antineoplastic activity against cancer. Major side effects are myelosuppression and neurotoxicity. Vindesine is used extensively in chemotherapy protocols (antineoplastic combined chemotherapy protocols). Vindesine acts by causing the arrest of cells in metaphase mitosis through its inhibition tubulin mitotic funcitoning. The drug is cell-cycle specific for the S phase."}]
