Epothilone B (Cat.No:I014009) is a naturally occurring compound isolated from bacteria. It belongs to the class of microtubule-stabilizing agents, similar to taxanes. Epothilone B exerts its anticancer effects by disrupting the dynamics of microtubules, leading to cell cycle arrest and apoptosis. It holds promise as a potential chemotherapy drug for various malignancies.
