Abstract
Taking in account the increased prevalence of metronidazole-resistant infections, alternative drugs are necessary for the treatment of trichomonosis. We report in this work the preparation and the in vitro anti-trichomonads activity of two diamines 1 and 2, and three different lipophilic amino alcohol derivatives 3, 4 and 5. These compounds were tested for in vitro activity against two isolates of Trichomonas vaginalis and displayed inhibition of the parasite growth. Five concentrations of each compound were tested. The butanediamine derivative 1, at a final concentration of 5.85 μM, presented a cytotoxic effect against 47% of T. vaginalis trophozoites. Furthermore, the cytotoxicity of 1 did not present statistically significant difference when compared to metronidazole in the same range of concentration (0.1–1.5 μg/mL).
