antimitotics through their covalent binding to the colchicine-binding site on intracellular beta-tubulin. The present communication aimed to evaluate the role of the electrophilic 2-chloroethyl amino moiety of CEU on cell growth inhibition and the specificity of the drugs as irreversible antagonists of the colchicine-binding site. To that end, several N-phenyl-N'-(2-ethyl)urea (EU), N-phenyl-N'-(2-chloroethyl)urea
