1. The in vitro metabolism of the new insecticide flupyrazofos was studied using rat liver microsomes. Two metabolites were produced and identified as O,O-diethyl O-(1-phenyl-3-trifluoromethyl-5-pyrazoyl) phosphoric acid ester (flupyrazofos oxon) and 1-phenyl-3-trifluoromethyl-5-hydroxypyrazole (PTMHP) based on UV and mass spectral analysis. 2. Cytochrome P450 oxidatively converted flupyrazofos to
1.使用大鼠肝脏微粒体研究了新型杀虫剂氟吡唑的体外代谢。产生了两种代谢物,鉴定为基于O,O-二乙基O-(1-苯基-3-三氟甲基-5-吡唑酰基)的磷酸酯(氟吡唑酮)和1-苯基-3-三氟甲基-5-羟基吡唑(PTMHP)进行紫外和质谱分析。2.细胞色素P450将氟吡唑氧化为氧,主要代谢产物和苯巴比妥诱导的微粒体将这种脱硫作用提高了8倍。3. Flupyrazofos oxon通过化学水解转化为PTMHP,半衰期为47.8分钟,并且在我们的微粒体温育条件下,这种转化也以非酶促方式进行。
