A series of aminoguanidine derivatives containing a biphenyl moiety were designed, synthesized, and characterized by spectra methods using chalcone-aminoguanidine derivative as the lead compound. The antibacterial activity of the target compounds was evaluated. The results indicated that most of the target compounds showed potent inhibitory activity with the minimum inhibitory concentration values (MICs) in range of 0.5~8 μg/mL. Among of which, 2-((4'-bromo-[1,1'- biphenyl]-4-yl)methylene)hydrazine-1-carboximidamide (3j) exhibited broad-spectrum antibacterial activity, effective to all the chosen strains including two multidrug-resistant gram-positive strains, showed the most potent inhibitory against S. aureus CMCC(B) 26003, E. faecalis CMCC 29212 and multidrug-resistant S. aureus ATCC 33591 with a MIC value of 0.5 μg/mL. Moreover, low cytotoxicity of compound 3j (HEK 293T, IC50=60.90 µmol/L) was found. These results suggested that the Compound 3j, with high safety, was potential and valuable in the research of novel antibacterial drugs.
