New compounds useful in photodynamic therapy are of the formula ##STR1## and their 1,4-diene isomers and the metallated and/or labeled and/or conjugated forms thereof

A method of administering photodynamic therapy begins with administering to an animal an effective amount of a photosensitizing agent which is less than about one half of the usual clinical dose for the photosensitizing agent. Then, following a post injection interval which is less about one quarter of the usual post injection interval, an effective dose of light which is less than about one half of the usual clinical dose of light used in conjunction with the photosensitizing agent is administered to the animal.
