Mechanism of action

The principal mechanism of the epothilone class is inhibition of microtubule function. Microtubules are essential to cell division, and epothilones therefore stop cells from properly dividing. Epothilone B possess the same biological effects as taxol both in vitro and in cultured cells. This is because they share the same binding site, as well as binding affinity to the microtubule. Like taxol, epothilone B binds to the αβ-tubulin heterodimer subunit. Once bound, the rate of αβ-tubulin dissociation decreases, thus stabilizing the microtubules. Furthermore, epothilone B has also been shown to induce tubulin polymerization into microtubules without the presence of GTP. This is caused by formation of microtubule bundles throughout the cytoplasm. Finally, epothilone B also causes cell cycle arrest at the G2-M transition phase, thus leading to cytotoxicity and eventually cell apoptosis.

Description
This 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.
