NCIt definition : A third generation, synthetic, water-soluble, pentapeptide analog of the marine depsipeptide
dolastatin 15, with potential antimitotic and antineoplastic activities. Tasidotin
and its metabolite, tasidotin C-carboxylate, suppress the dynamic instability behavior
of the microtubules through a reduction of the shortening rate (disassembly); reduction
of the switching frequency from growth to shortening; and by reducing microtubules
growth time. This may eventually result in a reduction of cell growth.;
