The Metabolism of Alicyclic Ketones in the Rabbit and Rat

Abstract
1. Rabbits and rats dosed with cyclopentanone, cyclohexanone or cycloheptanone excrete traces of the corresponding 2-hydroxycycloalkylmercapturic acids. 2. In each case small amounts of a second sulphur-containing metabolite are excreted. Mass spectroscopic evidence suggests that these metabolites are the sulphate esters of 2-hydroxycycloalkylmercapturic acids. 3. Cyclopentyl and cycloheptyl glucuronides are the major metabolites of cyclopentanone and cycloheptanone in the rabbit.
