In order to study the effect of steric hindrance on competition between two kinds of beta-hydroxylation, a compound bearing on a pyrimidinetrione nucleus both a branched side chain with a tertiary carbon atom in position beta (isobutyl group) and a linear side chain (ethyl group), was selected and administered to rats. Urine and faeces were collected and extracted. Hydroxymetabolites and their derivatives
为了研究空间位阻对两种β-羟基化之间竞争的影响,在嘧啶三酮核上带有一个化合物,该化合物同时具有在β位(异丁基)上带有叔碳原子的支链侧链和一个线性侧链(乙基)组),并选择对大鼠给药。收集并提取尿液和粪便。分离并鉴定了羟基代谢物及其衍生物。直链的β-羟基化比支链的β-羟基化更重要。立体位阻在该区域选择性中起决定性作用。
