Five of thiourea derivatives were prepared using as a starting compound 3-(trifluoromethyl)aniline, 4-chloro-3-nitroaniline, 1,3-thiazol-2-amine, 2H-1,2,3-triazol-4-amine and commercial isothiocyanates. All compounds were evaluated in vitro for antimicrobial activity. Derivatives 2 and 3 showed the highest inhibition against Gram-positive cocci (standard and hospital strains). The observed MIC values were in the range of 0.5–8 μg/ml. The products effectively inhibited the formation of biofilms of methicillin-resistant and standard strains of Staphylococcus epidermidis. Inhibitory activity of thioureas 2 and 3 against Staphylococcus aureus topoisomerase IV was studied. The examined compounds were nongenotoxic.
