Distamycin and nitrogenmustard conjugates, in which the nitrogenmustard unit was coupled to the C-terminus of the pyrrole, were synthesized. The switching of the nitrogenmustard unit from the N-terminus to the C-terminus did not compromise the compound's cytotoxicity. Compound 3, bearing three pyrrole units, was highly toxic to human K562 leukemia cells in vitro with an IC(50) value of 0.03 microM
