a comparison of the photosensitizing ability of a variety of porphyrins for photohaemolysis gives the following order of activity : protoporphyrin greater than deuteroporphyrin , mesoporphyrin , haematoporphyrin dimethyl ester much greater than haematoporphyrin diacetate , haematoporphyrin greater than haematoporphyrin monoacetate , coproporphyrin iii , haematoporphyrin derivative , coproporphyrin iii tetramethyl ester greater than uroporphyrin i , meso-tetra- ( n-methyl-4-pyridinium ) porphyrin tetratoluene-p-sulphonate , meso-tetra- ( p-carboxyphenyl ) porphyrin , protoporphyrin dimethyl ester , meso-tetra- ( p-hydroxy-sulphonylphenyl ) porphyrin tetrasodium salt , uroporphyrin iii , deuteroporphyrin-3,8-disulphonic acid and protohaemin .
