Purified compounds were characterized by UV, NMR, and mass spectrometry, by color reactions, and by chemical interconversions. Both species excreted 6- and 7-hydroxy-CPT besides the sulfoxide and demethylated analogues. In urine, the phenols were largely present as conjugates. The major metabolites in dog feces were 5-hydroxy-CPT and its demethylated derivative, whereas 5-hydroxylation was not detected in man. Dog excrete also contained 6-hydroxy-7-methoxy (or 7-hydroxy-6-methoxy)-CPT; further, a 5-hydroxy compound was detected in which the exocyclic double bond was hydrated. In the other metabolites, the Z-configuration of CPT had been retained, but small quantities of E-isomers were formed during isolation. According to preliminary quantitative data, phenols accounted for a small part of extractable metabolites in human urine, whereas they predominated in dog feces.
