Purified imines of porphyrins, chlorins, bateriochlorins, chlorophylls, bacteriochlorophylls, purpurins, reduced purpurins, verdins, Diels Alder adducts, benzochlorins and metal complexes of the foregoing imines are disclosed. The formulas of the benzochlorinimines and of the benzochlorinimine metal complexes are set forth below: ##STR1## In specific examples, M in the metal complexes is a copper cation that is complexed with two of the nitrogens of the benzochlorinimine R' and R'' are methyl, and R1 through R8 are ethyl.

Method of treating cancer tumors with imine porphyrin compounds

Purified imines of porphyrins, chlorins, bateriochlorins, chlorophylls, bacteriochlorophylls, purpurins, reduced purpurins, verdins, Diels Alder adducts, benzochlorins and metal complexes of the foregoing imines are disclosed for retarding growth of cancer tumors such as bladder tumors. The formulas of the benzochlorinimines and of the benzochlorinimine metal complexes are set forth below: ##STR1## In specific examples, M in the metal complexes is a copper cation that is complexed with two of the nitrogens of the benzochlorinimine R' and R'' are methyl, and R1 through R8 are ethyl.
