    Abstract:
    A series of 1,2,3-triazole-derived naphthalimides as a novel type of potential antimicrobial agents were synthesized and characterized by IR, NMR and HRMS spectra. All the new compounds were screened for their antimicrobial activity against four Gram-positive bacteria, four Gram-negative bacteria and three fungi. Bioactive assay manifested that 3,4-dichlorobenzyl compound 9e and its corresponding hydrochloride 11e showed better anti-Escherichia coli activity than Norfloxacin and Chloromycin. Preliminary research revealed that compound 9e could effectively intercalate into calf thymus DNA to form compound 9e-DNA complex which might block DNA replication and thus exert antimicrobial activities. Human serum albumin could effectively store and carry compound 9e by electrostatic interaction.
