In this paper, we describe the synthesis and the action against of the trypomastigote form of Trypanosoma cruzi of a new class of nitroimidazole‐2‐carbaldehyde O ‐benzyloximes. These derivatives were designed through the application of molecular hybridization concept between two potent antiprotozoal compounds, the 5‐nitrothiophene‐2‐carbaldehyde O ‐oxime 6 and the trypanocidal piperidinyl‐4‐carbaldehyde O ‐benzyloxime 7 with the intention of reaching two distinct molecular targets of T. cruzi . The activity of these benzyl ether derivatives was tested against the infective trypomastigote forms of T. cruzi , and the derivative ( E )‐1‐methyl‐5‐nitro‐1 H ‐imidazole‐2‐carbaldehyde O ‐(4‐nitrobenzyl) oxime ( 1 ) presented moderate trypanocidal activity (IC 50 = 12.7 μ M ) when compared with the standard drug benznidazole, which showed to be a good starting point for the design of more effective trypanocide agents.
