Evaluation of the Pharmacokinetics and Hepatoprotective Effects of Phillygenin in Mouse.

ABSTRACT: Phillygenin is a bioactive intergradient in Osmanthus fragrans, a well-known food additive and Chinese traditional medicine. This study was to investigate the hepatoprotective effects and pharmacokinetics of phillygenin. The hepatoprotective effect of phillygenin was assessed in carbon tetrachloride- (CCl₄-) intoxicated mice by monitoring levels of serum and tissue biomarkers. The pharmacokinetics of phillygenin was evaluated in the mouse after oral (po, 24?mg / kg) or intravenous (iv, 12?mg/kg) administration. Results showed that phillygenin has a great hepatoprotective effect on CCl4-induced liver injury in mice owing to its antioxidant activity and inhibition on cytochrome P450 2E1(CYP2E1). After oral administration, phillygenin was efficiently absorbed with the oral bioavailability of 56.4%. Two metabolites, hydroxylated and dimethylated phillygenin, were identified in mouse urine. These results suggested that phillygenin could be explored as new and potential natural antioxidants and hepatoprotective agents.

Project description:Cardiac and hepatotoxicities are major concerns in the development of new drugs. Better alternatives to other treatments are being sought to protect these vital organs from the toxicities of these pharmaceuticals. In this regard, a preclinical study is designed to investigate the histopathological effects of a new succinimide derivative (Comp-1) on myocardial and liver tissues, and the biochemical effects on selected cardiac biomarkers, hepatic enzymes, and lipid profiles. For this, an initially lethal/toxic dose was determined, followed by a grouping of selected albino rats into five groups (each group had n = 6). The control group received daily oral saline for 8 days. The 5-FU (5-Fluorouracil) group received oral saline daily for 8 days, added with the administration of a single dose of 5-FU (150 mg/kg I.P.) on day 5 of the study. The atenolol group received oral atenolol (20 mg/kg) for 8 days and 5-FU (150 mg/kg I.P.) on day 5 of the protocol. Similarly, two groups of rats treated with test compound (Comp-1) were administered with 5 mg/kg I.P. and 10 mg/kg I.P. for 8 days, followed by 5-FU (150 mg/kg I.P.) on day 5. Toxicity induced by 5-FU was manifested by increases in the serum creatinine kinase myocardial band (CK-MB), troponin I (cTnI) and lactate dehydrogenase (LDH), lipid profile, and selected liver enzymes, including ALP (alkaline phosphatase), ALT (alanine transaminase), AST (aspartate aminotransferase), BT (bilirubin total), and BD (direct bilirubin). These biomarkers were highly significantly decreased after the administration of the mentioned doses of the test compound (5 mg/kg and 10 mg/kg). Similarly, histological examination revealed cardiac and hepatic tissue toxicity by 5-FU. However, those toxic effects were also significantly recovered/improved after the administration of Comp-1 at the said doses. This derivative showed dose-dependent effects and was most effective at a dose of 10 mg/kg body weight. Binding energy data computed via docking simulations revealed that our compound interacts toward the human beta2-adrenergic G protein-coupled receptor (S = -7.89 kcal/mol) with a slight stronger affinity than the calcium channel T-type (S = -7.07 kcal/mol). In conclusion, the histological and biochemical results showed that the test compound (Comp-1) had prominent cardioprotective, hepatoprotective, and lipolytic effects against 5-FU-induced toxicity in the subjected animal model.
