ABSTRACT:
Novel photosensitizers related to rhodoporphyrins and phylloerythrin methyl ester, their preparation and use as photosensitizers for detection and treatment of tumors by photodynamic therapy. The novel photosensitizers accumulate and concentrate preferentially in tumor tissue, have strong light absorption in the 650 to 700 nm region and have reduced skin phototoxicity.
