Several structural analogues of the polyketide passifloricin lactone were synthesized using asymmetric stereoselective allylations and ring-closing methateses as key reactions. These compounds were active in vitro against intracellular amastigotes of Leishmania panamensis (strain UA 140), trophozoites of Plasinodium falciparum (strain NF54), and Mycobacterium tuberculosis (strain H(37)Rv). However, in spite of the significative antiparasitic activity of some synthetic analogues a high cytotoxicity was also observed. Based on these results a lactam derivative was also synthesized. This compound maintained a good level of activity with less toxicity. (c) 2006 Elsevier Ltd. All fights reserved.
