Hydrolysis of oleylanilide in the rat

Hydrolysis of oleylanilide in the rat The fate of oleylanilide, administered as a single intragastric dose in rape oil, has been studied in Porton Wistar rats. Following a dose of oleyl[U-14C]anilide approximately 60% of the label was recovered in the faeces over a 3 day period, and identified principally as unchanged anilide. Most of the remainder of the dose was recovered in urine as hydrophilic metabolites,p-hydroxyacetanilide, which is a major metabolite of aniline in the rat was identified in the hydrolysed samples of urine from anilide treated rats. Following administration of [9,10(n)-3H]oleyl[U-14C]-anilide to rats which had been fitted with a cannula in the thoracic lymph duct the [3H] label which was absorbed was recovered principally in triglycerides showing that extensive hydrolysis of the anilide occurs prior to or during uptake from the gut. Oleylanilide was identified in lymph by gas chromatography but amounted to less than 6% of the dose. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Toxicology Springer Journals

Abstract

The fate of oleylanilide, administered as a single intragastric dose in rape oil, has been studied in Porton Wistar rats. Following a dose of oleyl[U-14C]anilide approximately 60% of the label was recovered in the faeces over a 3 day period, and identified principally as unchanged anilide. Most of the remainder of the dose was recovered in urine as hydrophilic metabolites,p-hydroxyacetanilide, which is a major metabolite of aniline in the rat was identified in the hydrolysed samples of urine from anilide treated rats. Following administration of [9,10(n)-3H]oleyl[U-14C]-anilide to rats which had been fitted with a cannula in the thoracic lymph duct the [3H] label which was absorbed was recovered principally in triglycerides showing that extensive hydrolysis of the anilide occurs prior to or during uptake from the gut. Oleylanilide was identified in lymph by gas chromatography but amounted to less than 6% of the dose.
