title: Metabolism in rats of several carboxylic acid derivatives containing the 3,4-methylenedioxyphenyl group.
abstract: The metabolism of the 3,4-methylenedioxy derivatives of mandelic acid (1), phenylacetic acid (2), benzoic acid (3), 3-phenylpropionic acid (4) and cinnamic acid (5) was studied in rats. Following intragastric dosage (1 mmol/kg) the compounds and their metabolites were excreted in the urine within 24 hrs. Recoveries of roughly 85% were obtained. Except for compound (1) which was excreted to a large extent unchanged, glycine conjugates were the major urinary metabolites. Compound (2) formed 3,4-methylenedioxyphenylacetylglycine whereas compounds (3), (4) and (5) were converted to 3,4-methylenedioxybenzoylglycine. No evidence was found with any of the compounds for demethylenation and subsequent excretion of catecholic metabolites.
