Abstract :

A spirin Eugenol Ester (AEE) is a promising drug candidate for treatment of inflammation, pain and fever and prevention of cardiovascular diseases with fewer side effects than its precursor, aspirin. Investigation on its metabolic process in target animal species will help to illustrate its action mechanism and to establish its residual mark compound to formulate its dosage. Six beagle dogs were orally given a dose of 20 mg.kg-1 of AEE and one dog was used to prepare blank liver microsomes. Their liver microsomes were prepared for in vitro study and their plasma and urine were collected for in vivo metabolic analysis using liquid chromatography tandem mass spectrometry (HPLC-MS/MS). In this study we identified 10 metabolites, M1, M2, M3, M4, M5 in phase I and M6, M7, M8, M9, M10 in phase II
