2-(4-Methyl-1-piperazinylmethyl) acrylophenone dihydrochloride (MPMAP) is a novel inhibitor of microtubule assembly in vitro and in vivo whose molecular mechanism of action has not been investigated (M. L. Mallevais, A. Delacourte, I. Lesieur, D. Lesieur, M. Cazin, C. Brunet, and M. Luyckx (1984) Biochimie 66, 477-482). We have examined the effect of MPMAP on the alkylation of tubulin by iodo[14C]acetamide and N,N'-ethylenebis(iodoacetamide) (EBI). MPMAP is a very potent inhibitor of tubulin alkylation by iodo[14C]acetamide. MPMAP gives half-maximal inhibition at a concentration of 15 microM. MPMAP also inhibits the alkylation of denatured tubulin and of aldolase, implying that it reacts strongly with sulfhydryl groups. MPMAP does not, however, interfere with formation by EBI of a crosslink between cysteines 239 and 354 in the beta subunit of tubulin, suggesting that these sulfhydryls are located in a cleft in the tubulin molecule.
