NCI Drug Dictionary


batabulin sodium 
A synthetic pentafluorophenylsulfonamide with potential antineoplastic activity. Batabulin sodium covalently binds to and selectively modifies the beta 1, beta 2, beta 3, and beta 4 isotypes of beta tubulin at a conserved cysteine residue, resulting in disruption of microtubule polymerization, collapse of the cytoskeleton, an increase in chromosomal ploidy, cell cycle arrest, and tumor cell apoptosis. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
