Antimicrobial activities of some phthalocyanine derivatives

Abstract

Some phthalocyanine and polymeric phthalocyanine complexes were studied for antimicrobial activity against seven bacteria (Staphylococcus aureus, Bacillus subtilis, Enterococcus faecalis, Moraxella catarrhalis, Escherichia coli, Enterobacter cloacae and Pseudomonas aeruginosa) and two yeast like fungi (Candida albicans and Candida tropicalis). Of these, 15 phthalocyanine complexes showed varied levels of antimicrobial activity against one or more test bacteria. Antimicrobial activity was detected in two phthalocyanine complexes against gram-positive S. aureus, in 15 phthalocyanine complexes against gram-negative M. catarrhalis and in one phthalocyanine complexe against P. aeruginosa. The best antimicrobial activity was observed in the chemical 9, 22, 26, 28 and 32.
