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.
一种用于治疗具有高
酪氨酸酶活性的肿瘤的组合物,包含
青霉胺与细胞毒性醛的反应产物,或其药学上可接受的盐或酯,以及药学上可接受的载体。优选化合物为5,5-二甲基-2-苯基-4-
噻唑烷
羧酸或5,5-二甲基-2-(2-羟基苯基)-4-
噻唑烷
羧酸,或其药学上可接受的盐或酯。治疗最好采用动脉内滴注。通过给予放射性
铜盐并扫描放射性聚集物,可以诊断适合使用这些组合物进行治疗的肿瘤。这将指示高
酪氨酸酶活性的部位。
