Application of molecular topology to the prediction of antiparasitic activity against Giardia intestinalis and Trichomonas vaginalis of 2-Acylamino-nitro-1,3-thiazole products

Abstract

Giardia intestinalis and Trichomonas vaginalis stand out for their clinical importance. G. intestinalis causes giardiasis, a parasitism of great epidemiological and clinical importance due to its high prevalence. T. vaginalis causes trichomoniasis, the non-viral sexually transmitted disease (STD) with the highest incidence in the world. Both parasitisms share the same pharmacological treatment: nitroimidazoles. Molecular topology has been applied in searching for derivatives of 2-Acylamino-nitro-1,3-thiazole with antiparasitic activity against G. intestinalis and T. vaginalis. After using linear discriminant analyses, results show a model that could correctly classify the activity of 92.85 % of the compounds studied in both parasites. To predict antiparasitic activity, a multilinear regression analysis was carried out that could explain 83.2 % of the variance in G. intestinalis, and 89.4 % in T. vaginalis. Finally, a molecular screening was carried out to look for new potentially active compounds against both parasites.
