Biochemical and Physiological Mechanisms
Ixabepilone (BMS-247550) is a bioavailable microtubule inhibitor, which binds to tubulin and promotes tubulin polymerization and microtubule stabilization, thereby arrests cells in the G2-M phase of the cell cycle and induces tumor cell apoptosis.

DescriptionThis compound belongs to the class of organic compounds known as epothilones and analogues. These are macrolides consisting of a 16-member lactone ring conjugated at the carbon 16 with a 1-(2-methyl-1,3-thiazol-4-yl)prop-1-en-2-yl group. Some epothilone analogues containing a lactam ring instead of the lactone ring.
External Descriptors epoxide - 1,3-thiazole - lactam - beta-hydroxy ketone - macrocycle
