A composition for therapy of tumors having high tyrosinase activity contains the reaction product of penicillamine with a cytotoxic aldehyde, or pharmaceutically acceptable salts or esters thereof, and a pharmaceutically acceptable vehicle. The preferred compounds are 5,5-dimethyl-2-phenyl-4-thiazolidine carboxylic acid or 5,5-dimethyl-2-(2-hydroxyphenyl)-4-thiazolidine carboxylic acid, or pharmaceutically acceptable salts or esters thereof. Treatment preferably comprises an intra-arterial drip. Diagnosis of tumors suitable for treatment by means of these compositions may be accomplished by administering a radioactive copper salt and scanning for accumulations of radioactivity. This will indicate sites of high tyrosinase activity. |
