Vinblastine

[5] Vinblastine is a component of a number of chemotherapy regimens, including ABVD for Hodgkin lymphoma, and along with methotrexate in the treatment of aggressive fibromatosis (desmoid tumor).

[14] Vinblastine treatment causes M phase specific cell cycle arrest by disrupting microtubule assembly and proper formation of the mitotic spindle and the kinetochore, each of which are necessary for the separation of chromosomes during anaphase of mitosis.

The inclusion of vinblastine allows for lower doses of bleomycin and reduced overall toxicity with larger resting periods between chemotherapy cycles.

[19] Vinblastine appears to be a peripherally selective drug due to limited brain uptake caused by binding to P-glycoprotein.

Enantioselective synthesis has been of considerable interest in recent years, as the natural mixture of isomers is not an economical source for the required C16'S, C14'R stereochemistry of biologically active vinblastine.

[23] Stereochemistry is controlled through a mixture of chiral agents (Sharpless catalysts), and reaction conditions (temperature, and selected enantiopure starting materials).

[24] Due to difficulty of stereochemical restraints in total synthetic processes, other semi-synthetic methods from precursors, catharanthine and vindoline, continue to be developed.

[25] Vinblastine was first isolated by Robert Noble and Charles Thomas Beer at the University of Western Ontario from the Madagascar periwinkle plant.
