fate of aprophen hydrochloride (2-diethylaminoethyl 2,2-diphenylpropionate) was studied in rats after intravenous administration. Both 14C-labeled and unlabeled aprophen were used in these studies. Blood samples were collected and analyzed to determine the identities of the metabolites formed. Utilizing high-performance liquid chromatography, desethylaprophen was identified as a major metabolite in ether-extracted
在静脉内给药后,在大鼠中研究了盐酸阿布芬(2-diethylaminoethyl 2,2-diphenylpropionate)的代谢命运。这些研究中均使用了14C标记的和未标记的aprophen。收集血样并进行分析以确定所形成代谢物的身份。利用高效液相色谱法,去乙基萘被定为大鼠乙醚提取样品中的主要代谢产物,静脉给药后1分钟可在血液样品中检测到。它最有可能是由细胞色素P-450依赖的单加氧酶将萘丙素N-去乙基化而形成的。发现合成的去乙基萘丙啶具有胆碱分解活性(即,它通过阻断乙酰胆碱刺激的豚鼠回肠的收缩而起毒蕈碱拮抗剂的作用,(α-淀粉酶从卡巴胆碱刺激的胰腺腺泡细胞中释放),也可以通过抑制[3H] N-甲基东pol碱与豚鼠回肠的毒蕈碱受体结合而产生。有趣的是,尽管去乙基萘丙啶的生物学效应比其大约低100倍,但它同样能够竞争豚鼠回肠毒蕈碱受体的结合位点。
