Vincristine sulfate

Research use only, not for human use.

Vincristine (sulfate) is an inhibitor of polymerization of microtubules by binding to tubulin with IC50 of 32 μM.

Vincristine (sulfate) is an inhibitor of polymerization of microtubules by binding to tubulin with IC50 of 32 μM.(In Vitro):Vincristine inhibits net addition of tubulin dimers at assembly ends of steady-state microtubules with Ki of 85 nM. Vincristine stabilizes the spindle apparatus resulting in failure of the chromosomes to segregate leading to metaphase arrest and inhibition of mitosis at low concentrations. At higher concentrations, Vincristine may disrupt and induce total depolymerization of microtubules. Vincristine induces apoptosis in tumor cells and inhibits SH-SY5Y cell proliferation with IC50 of 0.1 μM. Vincristine induces mitotic arrest and promots the expression of caspase-3 and -9 and cyclin B, while decreasing the expression of cyclin D. Vincristine induced neurotoxicity is caused by interference with microtubule function, which results in blockage of axonal transport and thus in axonal degeneration.(In Vivo):Vincristine (3 mg/kg, i.p.) induces mean growth delay of > 120 and > 52 day, and repopulates fractions of 0.06% and 5%, administrated in mice bearing bilateral subcutaneous xenografts Rh12 or Rh18, respectively.
