Competition between two metabolic pathways: oxidation and desulfuration in the thiobarbiturate series
摘要:
In order to study the competition between hepatic hydroxylation and desulfuration in the thiobarbiturate series, two compounds bearing a branched side chain with a tertiary carbon atom in position omega-1 were administered to rats over about one week, Urine and faeces were collected and extracted. The metabolites isolated were identified. It was shown that desulfuration was not the major metabolic pathway, and that, when it took place, it remained a minor process and was accompanied by gamma-hydroxylation into a tertiary alcohol.
