GC32753

Taltobulin (HTI-286)

Also known as (E,4S)-4-[[(2S)-3,3-dimethyl-2-[[(2S)-3-methyl-2-(methylamino)-3-phenylbutanoyl]amino]butanoyl]-methylamino]-2,5-dimethylhex-2-enoic acid

Taltobulin (HTI-286) (HTI-286), a synthetic analogue of the tripeptide hemiasterlin, is a potent antimicrotubule agent that circumvents P-glycoprotein-mediated resistance in vitro and in vivo· Taltobulin (HTI-286) inhibits the polymerization of purified tubulin, disrupts microtubule organization in cells, and induces mitotic arrest, as well as apoptosis
