Structure- antimicrobial activity relationship of a series of functionalized arylbenzothiazoles

The antibacterial activity of a series of functionalized arybenzothiazoles was investigated against Gram-positive pathogens including Staphylococcus aureus (ATCC 9144), Micrococcus luteus (LB14110), Salmonella enterica (NCTC 6017) and Gram-negative foodborne Pseudomonas aeruginosa (ATCC 9027), Escherichia coli (ATCC 8739). The antifungal activity was also evaluated against the opportunistic pathogenic yeast Candida albicans (ATCC 2091). The results displayed that these compounds exhibit a good antimicrobial activity compared with fusidic acid. The structure-antimicrobial activity relationships are also discussed
