Product Introduction
Introduction
Maytansinol is the common parent of Maytansinoids, which are esters of the former, and generally show anticancer effects. Maytansinol has been obtained in large quantities by Japanese scholars through fermentation and converted into maytansinoids. Maytan Chemicalbook drugs and their derivatives are very strong inhibitors of microtubule assembly. They can exhibit anti-mitotic effects at the sub-nanomolar level, and their ED50 (effective dose) is 10-5 ~ 10-4μg/mL. is an ideal anticancer drug.
