Abstract:
A rapid and convenient radioligand assay was used to characterise the interaction of several structurally diverse microtubule inhibitors with the colchicine binding domain of tubulin. Values determined for the inhibition of [3H]mebendazole binding to tubulin by colchicine, combretastatin A4, NSC 181928, NSC 321567, podophyllotoxin and tubulozole-C provided an independent measure of the relative potency of these compounds. This methodology has several advantages over the inhibition of [3H]colchicine binding as a technique for investigating the molecular mechanisms involved in determining tubulin-ligand interactions.
