Fosbretabulin disodium/康普瑞汀磷酸二钠
Fosbretabulin disodium is the water-soluble prodrug of Combretastatin A4 (CA4), which is a microtubule-targeting agent that binds β-tubulin with Kd of 0.4 μM in a cell-free assay. Fosbretabulin disodium inhibits the polymerization of tubulin with IC50 of 2.4 μM, and also disrupts tumor vasculature.
