ABSTRACT
Using Gallic acid as raw material, 1-(substituted aromatic acyl)-4-(3,4,5-trihydroxybenzoyl) thiosemicarbazone was prepared by a two-step reaction and a series of brand-new gallic acid amide derivatives that contained 1,3,4-thiadiazole were synthesized by cyclic reaction. The newly prepared compounds' Vibrio harveyi inhibition activities were evaluated. The results indicated that all compounds showed different degree of inhibitory activity on Vibrio harveyi. Among them, the best inhibition effect was shown by compound 5b and its minimum inhibitory concentration (MIC) was 0.0313mg/mL.
