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.

Male Sprague-Dawley rats were treated ip with beta-naphthoflavone (40 mg/kg/day) in corn oil or in DMSO for three days. Diphenaldehyde (90 mg/kg in DMSO) was injected ip 24 hr after pretreatment. The increase in the levels of aspartate aminotransferase, alanine aminotransferase, sorbitol dehydrogenase, gamma glutamyl transpeptidase, and lactate dehydrogenase was significantly lower in rats pretreated with BNF. This suggests that the BNF-induced P-450 isozyme systems have a protective effect against the acute hepatotoxicity of diphenaldehyde.
