代谢
生物丙烯菊酯在大鼠和人体内的代谢被认为是几乎100%的氧化过程。这是因为生物丙烯菊酯对酯基的水解非常抵抗,尽管可能会发生微不足道的少量水解。在人体内,生物丙烯菊酯主要通过CYP2C19代谢,同时也有一部分通过CYP2C8、CYP3A4和CYP2C9*2代谢。产生的代谢物包括通过环丙烷基团附近的烯丙基氧化生成初级醇,然后进一步氧化成羧酸;通过环丙烷部分的甲基氧化形成初级醇;通过五元环附近的烯丙基氧化形成初级醇,或者在这个位置形成环氧,然后水解成二醇。在大鼠体内,生物丙烯菊酯主要通过CYP2C6、CYP2C11和CYP3A1代谢,CYP1A1、CYP2A1和CYP3A2也有所贡献。大鼠代谢生物丙烯菊酯的速度大约是人类的大约15倍。
Metabolism of bioallethrin in both rats and humans is considered to be virtually 100% oxidative [A32818,A32819]. This is because bioallethrin is very resistant to hydrolysis of its ester group although a negligible amount of hydrolysis may occur. In humans bioallethrin is metabolized primarily by CYP2C19 with some metabolism by CYP2C8, CYP3A4, and CYP2C9*2 [A32818]. The metabolites produced include primary alcohols via allylic oxidation near the cyclopropane group and subsequent oxidation to carboxylic acid, formation of a primary alcohol via oxidation of a methyl group to located on the cyclopropane portion of the molecule, formation of a primary alcohol via allylic oxidation near the 5-membered ring or formation of an epoxide at this location and subsequent hydrolysis to a diol. In rats bioallethrin has been found to be metabolized mainly by CYP2C6, CYP2C11, and CYP3A1 with some contribution from CYP1A1, CYP2A1 and CYP3A2 [A32818]. Rats appear to metabolize bioallethrin at about 15 times the rate of humans.
