Zinc Protoporphyrin (Zn(II)-protoporphyrin IX) 是一种具有口服活性的，竞争性的血红素加氧酶-1 (HO-1) 抑制剂，显着减弱间苯三酚 (PG) 对 H2O2的保护作用。Zinc Protoporphyrin 可用作个体孕妇和儿童缺铁的筛查标志物，也用于评估人群铁状态与血红蛋白浓度的组合。Zinc Protoporphyrin 具有抗癌活性。
| 生物活性 | Zinc Protoporphyrin (Zn(II)-protoporphyrin IX) is an orally active and competitiveheme oxygenase-1 (HO-1)inhibitor and markedly attenuates the protective effects of Phloroglucinol (PG) against H2O2[1]. Zinc Protoporphyrin is used as a screening marker of iron deficiency in individual pregnant women and children, but also to assess population iron status in combination with haemoglobin concentration[2]. Zinc Protoporphyrin has anti-cancer activity[3]. |
