Synthesis and Anti-Vibrio Activity of Gallic Acid Derivatives Containing Acyl Thiourea Phenol
摘要
A series of gallic acid derivatives containing acyl thiourea phenol were designed and synthesized with gallic acid as a raw material, and their antibacterial activities were evaluated: the synthesized acyl thiourea phenol derivatives of gallic acid had certain anti-Vibrio activity at 1 mg/mL; compounds 4a and 4c showed good inhibitory activity against Vibrio harveyi, MIC was 0.0156 mg/mL; compound 4f also showed certain anti-Vibrio cholerae activity, MIC was 0.0313 mg/mL; compound 4g showed anti-Vibrio parahaemolyticus activity, MIC was 0.0156 mg/mL; this series of compounds has poor inhibitory activity against Vibrio vulnificus. Only compounds 4a, 4c, 4e, 4g, and 4j have weak inhibitory activity against Vibrio vulnificus, with MIC of 0.125 mg/mL.
