Vincristine-d3 sulfate is the deuterium labeled Vincristine sulfate. Vincristine sulfate (Leurocristine, NSC-67574, 22-Oxovincaleukoblastine) is a microtubule inhibitor that disrupts microtubule polymerization by binding to beta-tubulin (with a Ki of 85 nM in bovine), arrests the cell cycle and induces apoptosis. Vincristine sulfate inhibits cell replication, tumor blood flow and the proliferation of various cancer cells, while triggering effects such as oxidative stress, inflammation, calcium overload, epithelial-mesenchymal transition and peripheral neuropathic pain. Vincristine sulfate upregulates the expression of various transporters and nuclear receptors, and enriches gastric cancer stem-like cells. Vincristine sulfate is used in research related to various tumors including acute lymphoblastic leukemia, lymphoma, melanoma, gastric cancer, solid tumors and sarcomas[1][2][3][4][5][6][7][8].
