title: Biotransformation of trans-sobrerol. III. Metabolites of 8-hydroxycarvotanacetone in the rat.
abstract: The metabolism of 8-hydroxycarvotanacetone (HCA), a major metabolite of trans-sobrerol, was studied in female rats after a single oral dose. The metabolic pathways include hydroxylation, reduction to cis- and trans-sobrerol, glucuronylation and Michael addition with glutathione giving rise to mercapturic acids which then undergo reduction. Biological reduction appears to occur more readily for the alicyclic-saturated ketones (Michael adducts) than for the alpha, beta unsaturated ketones (HCA and hydroxylated metabolites). This is in agreement with the chemical reactivity of the compounds.
