1) Some of heterocyclic amines (Trp-P-1, Trp-P-2 and 2-amino-alpha-carboline) were degraded by the action of Fe-octacarboxyphthalocyanine-rayon(Fe-ocpc-rayon) in aqueous solutions. The presence of hydrogen peroxide in the solutions accelerated the degradation. Mutagens extracted from tabacco smoke also underwent the degradation by the Fe-ocpc-rayon.2) IQ was converted to red colored dimer by the action of a resin bearing Mn- or Fe-tetrakis (sulfonyl) porphine ligand in the presence of hydrogen peroxide.3) Hemin and chlorophyllin stimulated the degradation of benzo (a) pyrene-7,8-diol-9,10 epoxide, a potent carcinogenic metabolite of benzo(a)pyrene.

1)一些杂环胺(Trp-P-1、Trp-P-2和2-氨基-α-咔啉)在水溶液中被Fe-八羧基酞菁人造丝(Fe-ocpc-rayon)作用降解。溶液中过氧化氢的存在加速了降解。从烟草烟雾中提取的诱变剂也经历了 Fe-ocpc-rayon 的降解。2) 在过氧化氢存在下，通过带有 Mn- 或 Fe-四（磺酰基）卟啉配体的树脂的作用，IQ 转化为红色二聚体.3) 氯高铁血红素和叶绿酸刺激苯并 (a) 芘-7,8-二醇-9,10 环氧化物的降解，这是一种强效致癌代谢物苯并(a)芘。
