经临床试验,将与红光(λ=630nm)有协同作用的血卟啉衍生物(HPD)用作肿瘤的光动力学治疗是一种有前途的新的物理疗法。HPD 是血卟啉经化学反应而得到的一种卟啉的复杂混合物,假设该混合物的活性成份是二血卟啉。光动力学治疗取决于癌组织对 HPD 选择性的保留。受光而显色的继发性反应,通过单态氧的光动力学反应杀死癌细胞。红光在 In clinical trials, the use of hematoporphyrin derivatives (HPD) with a synergistic effect of red light (λ=630 nm) as a photodynamic therapy for tumors is a promising new physical therapy. HPD is a complex mixture of porphyrins obtained by chemical reaction of hematoporphyrin. It is assumed that the active ingredient of the mixture is dihematoporphyrin. Photodynamic therapy depends on the preservation of HPD selectivity in cancer tissues. The secondary reaction, which is colored by light, kills cancer cells by the photodynamic reaction of singlet oxygen. Red light
