The EPR and electronic spectral changes upon titration of systems consisting of (protoporphyrin IX)iron(III) chloride (Fe(PPIX)Cl) or its dimethyl ester (Fe-(PPIXDME)Cl) and imidazole derivatives with tetrabutylammonium hydroxide solution have been measured at 77 and 298 degrees K in various solvents.

Magnetic circular dichroism (MCD) spectra were observed to characterize the nature of the visible bands for high-spin Fe(III) protoheme derivatives with p-nitrothiophenolate, p-nitrophenolate, and methoxy anion as the fifth ligands in several solvents. The visible MCD bands for p-nitrophenolate heme

Transdermal drug delivery is an attractive approach for either local or systemic treatment in medicine. In the last decade, different active transdermal delivery methods have been further investigated such as cationic liposomal delivery and electroporation-enhanced delivery. In light of gaining

5-Aminolevulinic acid (5-ALA) and its esters have been under intense investigation to enhance the endogenous production of protoporphyrin IX (PpIX) in tumour cells for the purpose of photodynamic diagnosis. In this study we have investigated the use of exogenous PpIX

Application of porphyrins as photosensitizers is based on their light-triggered generation of reactive oxygen species (ROS) that may cause oxidative tissue damage and ultimately kill cells. Cellular membranes are the action grounds of many sensitizers due to their hydrophobic or
