Abstract

Ruthenium-catalyzed cross metathesis using biseugenol (1) with electron-deficient olefins methyl (2a) and ethyl (2b) acrylates, acrylic acid (2c), acrylonitrile (2d), and methyl methacrylate (2e) derivatives have been conducted to afford respective derivatives 3a-3e with good yields and excellent conversion rates. Activity of prepared compounds against trypomastigote and amastigote forms of Trypanosoma cruzi and mammalian cytotoxicity have been evaluated. The results obtained indicate that the IC50 values for amastigotes of compounds 3b and 3d are quite similar to those of biseugenol (1), but unlike this compound, they show reduced toxicities with SI values similar to those of the standard drug benznidazol.
