    The search for compounds with new structural scaffolds is an important tool to the discovery of new drugs against Chagas disease. We report herein the synthesis of 1,2,3‐triazoles obtained from eugenol and di‐hydroeugenol and their in vitro and in vivo trypanocidal activity. These derivatives were obtained by a three‐step objective route and were suitably characterized by 1H and 13C nuclear magnetic resonance spectroscopy and high‐resolution mass spectrometry. Two compounds (9 and 10 ) showed activity against epimastigote forms of Trypanosoma cruzi (Y strain) in the range 42.8–88.4 μM and were weakly toxic to cardiomyoblast cells (H9c2 cells). The triazole 10 was the most active derivative and could reduce more than 50% of parasitemia after a 100‐mg/kg oral treatment of mice infected with T. cruzi . Molecular docking studies suggested this compound could act as a trypanocidal agent by inhibiting cruzain, an essential enzyme for T. cruzi metabolism, usually inhibited by triazole compounds.
