Infection diseases caused by methicillin-resistant Staphylococcus aureus have been an increasing problem worldwide presenting significant morbidity and mortality rates. Thus, fourteen benzoic acid [(5-nitro-thiophen-2-yl)-methylene]-hydrazides were designed, synthesized and tested against standard (ATCC 25923) and multidrug-resistant strains of Staphylococcus aureus. All compounds exhibited significant bacteriostatic activity and, in such cases, also bactericidal activity, especially the p-COCH3 derivative with MIC = 0.14 mg/mL. The results have demonstrated the potential of synthesized compounds as alternative to the development of selective antimicrobial agents.
