Application
Vinblastine sulfate salt has been used:as a microtubule depolymerizing drug for the synchronization of human cell lines in G2/M phaseas a multidrug resistance screening substrate in human colon cancer cell line (HCT116) cell lineas an antimicrotubule agent in sub perineural glia of Drosophila brain
Biochem/physiol Actions
Plant alkaloid that inhibits microtubule assembly by binding tubulin and inducing self-association in spiral aggregates in a reaction that appears to be regulated by the C-terminus of β-tubulin and is enhanced by GDP and GTP. Depolymerizes microtubules. Arrests the cell cycle in G2/M-phase by blocking mitotic spindle formation. Triggers Raf-1 activation, phosphorylation of bcl-2-family proteins, induction of p53 expression, and apoptosis in several tumor cell lines. Substrate of Pgp and CYP3A4.
