Notes: 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.{19711,19713} 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).{19711} Epo B causes cell cycle arrest at nanomolar IC50 values in cell lines from ovarian, breast, lung, colon, prostate, and squamous cancer.{19714}
