The metabolism of 2,4-dioxo-3,3-diethyl-5-methyl-piperidine (I) was studied and its oxidation to 4,6-dioxo-5,5-diethyl-tetrahydronicotinic acid (V) demonstrated. In addition, as intermediary products in the transformation of the methyl group into the carboxyl group, 2,4-dioxo-3,3-diethyl-5-methyl-tetrahydro-pyridine (II) and 2,4-dioxo-3,3-diethyl-5-hydroxymethyl-tetrahydro-pyridine (III) were isolated
研究了2,4-二氧代-3,3-二乙基-5-甲基-哌啶(I)的代谢,并证明了其被氧化为4,6-二氧代5,5-二乙基四氢烟酸(V)。此外,作为甲基转化为羧基的中间产物,2,4-二氧代-3,3-二乙基-5-甲基-四氢吡啶(II)和2,4-二氧代-3,3从实验动物的尿液中分离出-二乙基-5-羟甲基-四氢吡啶(III)。喂狗时,这些产物部分不变地排泄,部分转化为V。尿液中,尤其是胆汁中也发现了III和V的葡萄糖醛酸。
