A family of benzochlorins, a family of verdins, a family of porphyrin derivatives and metal complexes thereof are disclosed. the benzochlorins have the formula of FIG. 3 of the attached drawings; their metal complexes have the formula of FIG. 1. The verdins have the formula of FIG. 4 of the attached drawings; their metal complexes have the formula of FIG. 2. The porphyrin derivatives have the formula of FIG. 9 of the attached drawings; their metal complexes have the formula of FIG. 10. Solutions of the benzochlorins, verdins, porphyrin derivatives and metal complexes which are physiologically acceptable for intravenous administration are also disclosed, as are emulsions or suspensions of the solutions, and compositions which additionally include cyclodextrin, and wherein the molecules of the benzochlorin, verdin, prophyrin derivative or metal complex are encapsulated within the molecules of the cyclodextrin. The solvent for the solutions can be a product of the reaction of ethylene oxide with castor oil. A method for detecting and treating tumors in human and animal patients is also disclosed. The method comprises administering one of the benzochlorins, verdins, porphyrin derivatives or metal complexes to the patient. For detection, the tumor area is then illuminated with ultra violet light; for treatment, the tumor area is illuminated with visible light of a wavelength at which the benzochlorin, verdin, porphyrin derivative or complex administered shows an absorption peak.
本发明揭示了苯并氯菁家族、绿菁家族、卟啉衍生物家族及其金属配合物家族。苯并氯菁的分子式为附图3;其金属配合物的分子式为附图1。绿菁的分子式为附图4;其金属配合物的分子式为附图2。卟啉衍生物的分子式为附图9;其金属配合物的分子式为附图10。本发明还揭示了生理上可接受用于静脉注射的苯并氯菁、绿菁、卟啉衍生物及其金属配合物的溶液,以及这些溶液的乳剂或悬浮液,和还包括环糊精的组成物,其中苯并氯菁、绿菁、卟啉衍生物或金属配合物的分子被封装在环糊精的分子内。溶液的溶剂可以是乙氧基化蓖麻油的反应产物。本发明还揭示了一种检测和治疗人和动物患者肿瘤的方法。该方法包括向患者注射苯并氯菁、绿菁、卟啉衍生物或金属配合物之一。对于检测,肿瘤区域然后用紫外光照明;对于治疗,肿瘤区域则用所注射的苯并氯菁、绿菁、卟啉衍生物或配合物显示吸收峰的可见光波长照明。
