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 Obenzyloxime 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-1H-imidazole-2-carbaldehyde O-(4-nitrobenzyl) oxime (1) presented moderate trypanocidal activity (IC50 = 12.7 μM) when compared with the standard drug benznidazole, which showed to be a good starting point for the design of more effective trypanocide agents.2030-01-01
