Microwave-assisted synthesis of 5,10,15,20-tetrakis(4-nitrophenyl)porphyrin and zinc derivative and study of their bacterial photoinactivation
Journal Title: Iranian Chemical Communication - Year 2016, Vol 4, Issue 2
Abstract
In this study, 5,10,15,20-tetrakis(4-nitrophenyl)porphyrin (TNPP) and its zinc porphyrin complex (ZnTNPP) were synthesized in situ using the microwave method and identified by UV-Vis, FT-IR and 1H NMR. The photostability and photodynamic antimicrobial activity (PACT) of these compounds were investigated on Pseudomonas aeruginosa and Bacillus subtilis under visible light irradiation. MIC, MBC and inhibition zones produced by these compounds were determined and the number of bacteria counted. The results indicated that both compounds have significant stability when illuminated for various illumination periods in nutrient broth media. Both compounds exhibited more effective activity against P. aeruginosa than B. subtilis in nutrient agar.
