Synthesis and Antimicrobial Activity of a Pyridine Complex of (Acetato)[5,10,15,20-tetrakis(N-methylpyridin- 4-yl)porphinato]manganese(III) Tetratosylate

Aiming at preparation of new biologically active donor‒acceptor complexes, a water-soluble manganese(III) complex with 5,10,15,20-tetrakis( N -methylpyridin-4-yl)porphine tetratosylate was synthesized and its reaction with pyridine was studied by spectrophotometry using the molar ratio method. In water a 1: 1 donor‒acceptor complex with pyridine is formed. The chemical structure of the compounds was established by spectral methods. (Acetato)[5,10,15,20-tetrakis( N -methylpyridin-4-yl)porphinato]manganese(III) tetratosylate and especially its donor‒acceptor complex with pyridine showed an antifungal activity against Candida albicans .
