Mechanism of the formation in vivo of α-phenyl-γ-lactones in the glutethimide series
摘要:
The isolation of gamma-lactones from the urines of humans or animals treated with glutethimide or aminoglutethimide required an explanation. The question was studied on the glutethimide model. Potential metabolites such as beta-hydroxymetabolite, gamma-lactone amide, and gamma-lactone acid were synthesized. Glutethimide was first administered to rats at high and normal doses. The corresponding gamma-lactone amide, resulting from alcoholysis of beta-hydroxyglutethimide, was also administered to rats. The amounts of the various gamma-lactone derivatives isolated from the urine were discussed and it was concluded that the alpha-phenyl-gamma-lactone was formed in vivo via beta-hydroxylation of glutethimide followed by intramolecular alcoholysis. The lactone amide was then oxidized and dealkylated via an intramolecular mechanism leading to the corresponding alpha-phenyl-gamma-lactone.
