Photodynamic inactivation of Enterococcus faecalis by non-peripherally substituted magnesium phthalocyanines entrapped in lipid vesicles

Photophysical properties and photodynamic potential of magnesium phthalocyanines bearing 2-propoxy, benzyloxy, 3,5-bis(benzyloxy)benzyloxy at non-peripheral positions was studied. In in vitro antimicrobial photodynamic inactivation study, log reductions of bacterial (Enterococcus faecalis) growth at 3.61, 2.99 were obtained for liposomal formulations containing non-peripherally substituted 2-propoxy and benzyloxy phthalocyanines, respectively.277
