代谢
在给予大鼠丙纶甘油中50毫克/千克的1,2-二溴-3-氯丙烷(DBCP)后,在尿液中发现了S,S'-(2-羟基丙烷-1,3-二基)双巯基尿酸酸和S-(2,3-二羟基丙基)巯基尿酸酸作为代谢物。DBCP的代谢途径包括氧化和水解成一系列环氧代谢物,以及从环氧化合物形成男性抗生育剂α-氯醇和α-溴醇。后两个化合物的氧化代谢成草酸,可能引起肝脏损害。
Following intraperitoneal admin of 50 mg/kg of 1,2-dibromo-3-chloropropane (DBCP) to rats in propylene glycol, S,S'-(2-hydroxypropane-1,3-diyl)bismercapturic acid & S-(2,3-dihydroxypropyl)mercapturic acid were found as metabolites in urine. The metabolic pathway for DBCP incl oxidation & hydrolysis to a series of epoxide metabolites, and formation of male anti-fertility agents alpha-chlorohydrin & alpha-bromohydrin from epoxides. Subsequent oxidative metabolism of these latter two cmpd to oxalic acid presumably causes liver damage.
