Vinblastine is an anti-mitotic drug used as an antineoplastic drug to treat certain kinds of cancer, including Hodgkin's lymphoma, non-small cell lung cancer, breast cancer, head and neck cancer, and testicular cancer.
History[]
Vinblastine was first isolated by Robert Noble and Charles Thomas Beer from the Madagascar periwinkle plant. Vinblastine's utility as a chemotherapeutic agent was first discovered when it was crushed into a tea. Consumption of the tea led to a decreased number of white blood cells; therefore, it was hypothesized that vinblastine might be effective against cancers of the white blood cells such as lymphoma.
Pharmacology[]
Vinblastine is a vinca alkaloid and a chemical analogue of vincristine. It binds tubulin, thereby inhibiting the assembly of microtubules. It is M phase cell cycle specific since microtubules are a component of the mitotic spindle and the kinetochore which are necessary for the separation of chromosomes during anaphase of mitosis. Toxicities include bone marrow suppression (which is dose-limiting), gastrointestinal toxicity, potent vesicant (blister-forming) activity, and extravasation injury (forms deep ulcers).
Vinblastine paracrystals may be composed of tightly-packed unpolymerized tubulin or microtubules.[1]
Indications[]
Vinblastine is a component of a number of chemotherapy regimens, including ABVD for Hodgkin lymphoma. It is also used to treat histiocytosis according to the established protocols of the Histiocytosis Association of America.
