Novel dinitroaniline sulfonamides based on the herbicide oryzalin 3 were synthesized and evaluated for activity against the parasitic protozoan Leishmania donovani and against leishmanial tubulin, the putative antiparasitic target of oryzalin. A subset of these compounds possess more activity against both Leishmania and the target protein in vitro. Compound 20 displays improved potency against leishmanial tubulin and is 13.4-fold more active against L. donovani axenic amastigotes than oryzalin. (C) 2002 Elsevier Science Ltd. All rights reserved.
