KOS-1584

KOS-1584 is a second-generation epothilone antineoplastic agent that stabilizes microtubules, inducing cell cycle arrest and apoptosis. Its optimized profile offers improved water solubility, tumor penetration, and reduced neurotoxicity compared to earlier analogs, while also demonstrating low susceptibility to P-glycoprotein efflux mechanisms. This profile supports its investigation in both in vitro cytotoxicity assays and in vivo tumor model studies.
