A number of aminoalcohols, diamines and other related cycloanalogues of sphingosine have been synthesized and assayed in vitro against three Leishmania spp. and Trypanosoma cruzi. Most of the compounds were potent parasiticides, with IC50 values in the microM or lower range and potencies higher than those of pentamidine and benznidazol, the common therapeutic agents against these parasitoses.
