Abstract
A series of novel positively-charged porphyrins is disclosed which exhibit a markedly increased efficiency in photosensitizing both Gram-positive and Gram-negative bacteria to the action of visible light, causing death to such bacteria when present at much lower concentrations and much shorter irradiation times than those porphyrins taught in the prior art. These porphyrins are characterized by the presence of up to four positive charges in the peripheral substituents and at least one hydrophobic tail comprising between 6 and 22 carbons inclusive, originating at one or more of the charged sites.
