    • PROBLEM TO BE SOLVED: To provide an antitumor agent having high local accumulation ability to a tumor part, excellent in antitumor activity and scarcely having adverse effect in order to solve problems in which a method for administering a metal porphyrin derivative such as Zn-protoporphyrin (ZnPP) effective as an antitumor agent is limited because of slightly water-soluble derivative and it is difficult to locally accumulate the agent in the tumor part.
      SOLUTION: This antitumor agent comprises the metal porphyrin derivative bonded to an amphiphilic or a water-soluble polymer and having hemoxygenase- inhibiting activity, particularly Zn-protoporphyrin (ZnPP) bonded to polyethylene glycol as an active ingredient.

    • 要解决的问题:为了提供对肿瘤部位具有高的局部蓄积能力的抗肿瘤剂,抗肿瘤活性优异且几乎不具有不利影响,以解决其中施用诸如Zn-原卟啉的金属卟啉衍生物的方法( 作为抗肿瘤剂有效的ZnPP)由于轻微的水溶性衍生物而受到限制,并且难以在肿瘤部位局部积聚该药剂。 解决方案:该抗肿瘤剂包含与两亲性或水溶性聚合物结合并具有氧合酶抑制活性的金属卟啉衍生物,特别是与聚乙二醇结合的Zn-原卟啉(ZnPP)作为活性成分。
