代谢
在代谢研究中,以下代谢物在大鼠尿液中被发现,这些大鼠已经喂食了8000 ppm的丙泊磷13周:M1 = 1,2-二羟基苯(=儿茶酚);M2 = 2-异丙氧基酚;M3 = 2-羟基苯甲基碳酰胺;M4 = 2-异丙氧基苯基碳酰胺酸;M5 = 异丙氧基苯基-羟基甲基碳酰胺;M6 = 2-异丙氧基-5-羟基苯基甲基碳酰胺;M7 = 2-异丙氧基-5-羟基苯基碳酰胺酸;M8 = 2-异丙氧基-5-羟基苯基羟甲基碳酰胺;M9 = 1,5-二羟基-2-异丙氧基苯。在附加研究中,M6(= 2-异丙氧基-5-羟基苯基甲基碳酰胺)被确认为仓鼠、小鼠和人类的主要代谢物。硝化化合物M9A(= 1-羟基-2-异丙氧基-4-硝基苯)已在大鼠、小鼠、猕猴和人类中被确认为代谢物。来自人类研究的证据表明M9A是在胃中合成的。
In a metabolism study, the following metabolites were identified in the urine of rats which had been fed 8000 ppm propoxur for 13 weeks: M1 = 1,2-dihydoxybenzene (= catechol); M2 = 2-isopropoxyphenol; M3 = 2-hydroxyphenyl methylcarbamate; M4 = 2- isopropoxyphenylcarbamic acid; M5 = isopropoxyphenyl-hydroxy(-) methylcarbamate; M6 = 2-isopropoxy-5-hydroxyphenyl-methylcarbamate; M7 = 2-isopropoxy-5-hydroxyphenyl carbamic acid; M8 = 2-isopropoxy-5-hydroxyphenylhydroxymethyl carbamate; M9 = 1,5-dihydroxy-2-isopropoxybenzene. In additional studies, M6 (= 2-isopropoxy-5-hydroxyphenylmethylcarbamate) was identified as a principle metabolite in hamsters, mice, and humans. The nitrosated compound M9A ( = 1-hydroxy-2- isopropoxy-4-nitrobenzene) has been identified as a metabolite in rats and mice, the rhesus monkey, and humans. Evidence from the human study suggests that M9A is synthesized in the stomach.
