The metabolites of 1-allyl-3,5-diethyl-6-chlorouracil in rabbit urine were isolated by preparative thick-layer, liquid-column, and gas chromatography. With the aid of mass and 1H-NMR spectra, and by comparison with an authentic sample, the major metabolite, 1, was identified as 6,8-diethyl-2-hydroxymethyl-tetrahydrooxazolo-[3,2-c]-pyrimidine-5,7(4H,6H)-dione, Metabolite 2 as 1-allyl-3-ethyl-5-(1-h
通过制备型厚层色谱,液柱色谱和气相色谱法分离兔尿中1-烯丙基-3,5-二乙基-6-氯尿嘧啶的代谢产物。借助质谱和1H-NMR谱,并与真实样品进行比较,主要代谢物1被鉴定为6,8-二乙基-2-羟甲基-四氢恶唑基-[3,2-c]-嘧啶- 5,7(4H,6H)-二酮,代谢物2为1-烯丙基-3-乙基-5-(1-羟乙基)-6-甲基硫尿嘧啶,代谢产物3为1-烯丙基-3,5-二乙基-6-甲基硫尿嘧啶,和代谢物4为6,8-二乙基-2-羟甲基-四氢噻唑-[3,2-c]嘧啶-5,7(4H,6H)-二酮。探讨了含硫代谢物的形成机理,并提出了新的甲硫基化合物代谢途径。
