NCIt definition : An analogue of the naturally occurring tripeptide hemiasterlin, with potential antimitotic
and antineoplastic activities. Taltobulin binds tubulin in a similar manner as colchicine
and inhibits tubulin polymerization. This results in the disruption of the cytoskeleton,
ultimately leading to cell cycle arrest in G2/M phase, blockage of cell division and
apoptosis.;
