A series of 3-acetyl-2,5-disubstituted-2,3-dihydro-1,3,4-oxadiazole derivatives was synthesized and their activity screened in vitro against Staphylococcus aureus, Trypanosoma cruzi, and Candida albicans. The bioactivity was expressed as minimum inhibitory concentration (MIC) for S. aureus strains, and as fifty-percent inhibitory concentration (IC50) of parasite population growth for T. cruzi. A molecular modeling approach was performed to establish qualitative relationships regarding the biological data and the compounds' physicochemical properties. The 5-(4-OC4H9Ph, 5μ), and 5-(4-CO2CH3Ph, 5o) derivatives were the most active compounds for S. aureus ATCC 25923 (MIC = 1.95 -1.25 μg/mL) and T. cruzi (IC50 = 7.91 μM), respectively. Also, a preliminary evaluation against C. albicans involving some compounds was performed and the 5-(4-CH 3Ph, 5e) derivative was the most active compound (MIC = 3.28-2.95 μg/mL). In this preliminary study, all synthesized 3-acetyl-2,5- disubstituted-2,3-dihydro-1,3,4-oxadiazole derivatives were active against all microorganisms tested.
