Description and Uses

Epothilone B (152044-54-7) induces microtubule polymerization. Causes cell cycle arrest at the G2-M transition (EC50 = 32 nM for HeLa cells). Induces apoptosis. Cell permeable.

Epothilone B (Epo B) is a macrolide that causes the formation of bundles of intracellular microtubules in non-mitotic cells, induces the formation of hyperstable tubulin polymers, and arrests cell cycling in mitosis. It induces mitotic arrest at the G2-M transition in Hs578T and HeLa cells (IC50 = 3 and 32 nM, respectively) as well as in multidrug resistant KB3-1 and KBV-1 cells (IC50 = 16 and 92 nM, respectively). Epo B causes cell cycle arrest at nanomolar IC50 values in cell lines from ovarian, breast, lung, colon, prostate, and squamous cancer.
