Oxidative processes catalysed by metalloporphyrins nowadays are gaining importance in the study of various biological systems. One of the main direction of the investigations with synthetic metalloporphyrin catalysts is the development of systems which are capable of reproducing oxidative processes mediated by hem proteins (such as cytochrome P450, lignin peroxidase, nitric oxide synthesize (NOS), etc.). Another possible application is to develop systems containing metalloporphyrin catalyst, which could selectively oxidize organic compounds or detoxicate polluting agents at industrial level. We proved the benefits of the application of pentafluoride iron porphyrin used in three fields:--in the insect selective cytochrome P450 catalysed metabolism of carbamate insecticides [1],--to verify the natural decomposition path of insect selective cytochrome P450 inhibitors (metabolic pathways of lignin peroxidase) [2],--in modelling the H2O2 dependent NOS catalysed oxidation of the N-hydroxyguanidine based NO donors [3].
如今,金属卟啉催化的氧化过程在各种生物系统的研究中变得越来越重要。使用合成金属卟啉催化剂进行研究的一个主要方向是开发能够重现由血红素蛋白介导的氧化过程的系统(如细胞色素P450、木质素过氧化物酶、一氧化氮合酶(NOS)等)。另一个可能的应用是开发含有金属卟啉催化剂的系统,该系统可以在工业层面上选择性地氧化有机化合物或使污染剂解毒。我们证明了五氟铁卟啉在三个领域应用的益处:——在昆虫选择性细胞色素P450催化的氨基甲酸酯类杀虫剂代谢中[1],——验证昆虫选择性细胞色素P450抑制剂的自然分解途径(木质素过氧化物酶的代谢途径)[2],——模拟依赖H2O2的NOS催化的基于N-羟基胍的NO供体的氧化[3]。
