Information Vincristine (NSC-67574) sulfate Vincristine sulfate (NSC-67574, Leurocristine, Oncovin, 22-Oxovincaleukoblastine) is an inhibitor of polymerization of microtubules by binding to tubulin with IC50 of 32 μM in a cell-free assay. Vincristine sulfate induce Vincristine inhibits net addition of tubulin dimers at assembly ends of steady-state microtubules with Ki of 85 nM. At low concentrations, Vincristine stabilizes the spindle apparatus resulting in failure of the chromosomes to segregate leading to metaphase arrest and inhibition of mitosis. 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) administrated by a single i.p. injection to mice bearing bilateral subcutaneous xenografts Rh12 or Rh18, induces mean growth delay of >120 and >52 day, and repopulating fractions of 0.06% and 5%, respectively. Vincristine acts on subcutaneous colon 38 tumors in mice by host cell-mediated vascular effects as well as by direct tubulin-mediated cytotoxicity. Vincristine (5 mg/kg) reduces tumor blood flow of tumors by nearly 75% . cell?lines： Concentrations：10 nM Incubation?Time：3 days Powder?Purity:≥98% |
