代谢
活体和离体代谢3-二甲基氨基丙腈(DMAPN)及其对雄性Sprague-Dawley大鼠的泌尿毒性进行了研究。大鼠口服175、350或525毫克/千克DMAPN或DMAPN代谢物5天,并测量尿代谢物和体积。到第5天,44%的DMAPN剂量未改变地被排泄。通过气相色谱鉴定,β-氨基丙腈和氰乙酸是主要的尿代谢物。结论是,DMAPN通过细胞色素P450混合功能氧化酶系统代谢,DMAPN的泌尿毒性可能与它的代谢有关。
... In vivo and in vitro metabolism of 3-dimethylaminopropionitrile (DMAPN) and its urotoxic effect on male Sprague-Dawley rats /were investigated/. Rats were given 175, 350, or 525 mg/kg DMAPN or DMAPN metabolites orally for 5 days, and urinary metabolites and volumes were measured. By day 5, 44% of the DMAPN dose was excreted unchanged. Beta-aminopropionitrile and cyanoacetic acid were the major urinary metabolites, as identified by gas chromatography. /It was/ concluded that DMAPN is metabolized via a cytochrome P450 mixed-function oxidase system and the urotoxic effects of DMAPN may be related to its metabolism.
