Benznidazole inhibits the synthesis of DNA, RNA, and proteins within the T. cruzi parasite. Studies suggest that benznidazole is reduced by a Type I nitroreductase (NTR) enzyme of T. cruzi producing a series of short-lived intermediates that may promote damage to several macromolecules including DNA. In mammalian cells, however, benznidazole is metabolized by reduction of the nitro group to an amino group by a Type II NTR enzyme. The precise mechanism of action is not known. Benznidazole is active against all three stages, trypomastigotes, amastigotes, and epimastigotes, of T. cruzi. However, the sensitivity of T. cruzi strains to benznidazole, from different geographic regions, may vary.
