NCIt definition : The sulfate salt of a natural alkaloid isolated from the plant Catharanthus roseus
(Vinca rosea L.) with antimitotic and antineoplastic activities. Vincristine binds
irreversibly to microtubules and spindle proteins in S phase of the cell cycle and
interferes with the formation of the mitotic spindle, thereby arresting tumor cells
in metaphase. This agent also depolymerizes microtubules and may also interfere with
amino acid, cyclic AMP, and glutathione metabolism; calmodulin-dependent Ca(2 )-activated
ATPase activity; cellular respiration; and nucleic acid and lipid biosynthesis.;
Alternative definition : NCI-GLOSS: A drug used to treat acute leukemia. It is used in combination with other
drugs to treat Hodgkin disease, non-Hodgkin lymphoma, rhabdomyosarcoma, neuroblastoma,
and Wilms tumor. Oncovin is also being studied in the treatment of other types of
cancer. It blocks cell growth by stopping cell division. It is a type of vinca alkaloid
and a type of antimitotic agent.;
