Diphenaldehyde is the major product of phenanthrene ozonized on silica gel. Male Sprague-Dawley rats were treated with a single ip injection of DMSO (3.0 ml/kg) or diphenaldehyde (90 mg/kg) in DMSO. Diphenaldehyde produced significant alterations in levels of serum aspartate aminotransferase, alanine aminotransferase, sorbitol dehydrogenase, gamma-glutamyl transpeptidase, and lactate dehydrogenase relative to DMSO-injected rats 24 hr after injection. These results, as well as gross observations on necropsy, suggest that diphenaldehyde exhibits significant hepatotoxicity.
