Synthesis and antimicrobial activities of 2,5-substituent hydroquinone derivatives

Abstract

A series of 2,5-substituent hydroquinone derivatives were designed and synthesized. Their structures were identified by elemental analysis, 1H NMR, IR spectra. Their assayed antibacterial (Escherichia coli, Bacillus subtilis) and antifungal (Candida albicans) activities were also evaluated by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) method. The results of biological test showed compounds 1 and 10 have favorable antimicrobial activity with MICs of 20.5, 24.6, 18.9 and 28.6 μg/mL against Escherichia coli and Bacillus subtilis, respectively.
