Drug induced liver damage remains a prevalent concern in healthcare and may reduce the effectiveness of therapy by compromising therapeutic regimens. Many Commiphora species are known for their medicinal properties, and some of them are used traditionally for hepatoprotective effect. In the course of our drugs discovery from natural sources, phytosterols (lophenol (Lop) and lathosterol (Lat)), isolated from Commiphora kua were studied to evaluate their hepatoprotective effects in acetaminophen (APAP) induced hepatotoxicity in mice.
To evaluate the hepatoprotective effects of phytosterols isolated from C. kua using in vivo experimental model.
Mice of either sex were divided into 7 groups: Vehicle, silymarin (SLY), acetaminophen (APAP), Lop 25, Lop 50, Lat 25, Lat 50 (n = 5). Vehicle group received only vehicle (0.1% DMSO solution) for 7 days, APAP group received single dose of acetaminophen on day 7 and SLY group received silymarin for 7 days. Lop 25 and Lop 50 received low and high doses of Lop (25 μg/kg BW and 50 μg/kg BW), respectively, for 7 days, while Lat 25 and Lat 50 received low and high doses of Lat (25 μg/kg BW and 50 μg/kg BW) for 7 days. On day 7, all animals except Vehicle group kept fasted for 18 h and received APAP i. p. 400 mg/kg BW. After 20 h of APAP administration, the animals anesthetized with light chloroform and scarified by cervical decapitation. The blood serum and liver tissue samples were collected for biochemical and histopathological analysis. Liver function tests (LFTs) including lactate deydrogenase (LDH), alkaline phosphatase (ALP), alanine transaminase (ALT), aspartate transaminase (AST) and direct bilirubin) were used as biochemical parameters. While catalase (CAT), superoxide dismutase (SOD) and reduced glutathione (GSH) were taken as anti-oxidant enzymes.
Significant increase in levels of ALT, AST, ALP, LDH and direct bilirubin, and significant decrease in concentration of anti-oxidant enzymes (SOD, CAT and GSH) was observed in APAP-treated group. Similarly, histological slides showed obvious signs of damage to liver cells, reflecting acetaminophen induced hepatotoxicity. Treatment of test animals with phytosterols resulted in significant recovery of LFTs profile and concentration of anti-oxidant enzymes. Similarly, significant improvement of liver tissues was noted in histological analysis.
Both phytosterols possessed hepatoprotective potential and should be further evaluated for acute toxicity studies and pharmacokinetics/pharmacodynamics profile.
