Background: Traditionally, the bark of Pavetta Indica Linn., in decoction or pulverized, is administered, especially to children, to correct visceral obstructions. The decocted leaves are used externally to alleviate the pains caused by hemorrhoids. The root, pulverized and mixed with the ginger and rice-water, is given in dropsy. A local fomentation with the leaves is useful in relieving the pain of piles. Paracetamol (PCM) toxicity generates free radicals and raised serum enzyme levels-SGPT, SGOT, Alkaline Phosphatase and S. Albumin. It causes necrosis, congested vessels, multifocal area of fatty changes nuclear disintegration, sinusoidal dilation, kuffer cell hyperplasia. The reverse is considered as the index of hepatoprotective activity. The present study is being taken up to screen hepatoprotective action of P. Indica Linn.Methods: The acute liver damage in albino rats was induced by per oral administration of a single dose of 2000mg/kg b.w. PCM suspension in 0.5% Carboxy methyl cellulose (CMC) and chronic liver damage by giving the same dose of PCM on the 7th day. The hepatoprotective activity was monitored biochemically by estimating S. transaminase, S. bilirubin and S. Protein on the 8th day of experiment.Results: Ethanol extract of P. Indica inhibited PCM induced liver toxicity in albino rats at 100mg/kg and 200mg/kg b.w as assessed by the biochemical values.Conclusions: Ethanol extract of “P. Indica” exhibited significant hepatoprotective activity.

Context: Quinazolines are a common class of nitrogen-containing heterocyclic scaffolds exhibiting a broad spectrum of pharmacological activities. Objective: In the present study, quinazoline and quinazolin-4-one derivatives were prepared, characterized to evaluate their biological which may pave the way for possible therapeutic applications. Materials amp; Methods: A new derivative of quinazoline and quinazolin-4-one derivatives was prepared and tested for antiulcerogenic, anti-inflammatory and hepatoprotective activity. Results: The synthesized compounds were characterized by elemental analysis and spectral data. Also, the median lethal doses (LD50s) of compounds 1-3 in rats were 1125, 835 and 1785 mg/kg b.w., respectively. IC50 values of compounds (1-3) as measured by ABTS+ radical method was 0.8, 0.92 and 0.08 mg/mL, respectively. Antiulcerogenic activities at dose 1/20 LD50 in albino rats were 47.94, 24.60 and 56.45%, respectively. Anti-inflammatory effect at dose 1/20 LD50 of compounds (1-3) induced edema model after 120 min. The prepared compounds possess hepato gastric mucosa protective activity against ibuprofen-induced ulceration and LPS-induced liver toxicity, respectively in rats via normalization of oxidative stress biomarkers and inflammatory mediators were inhibited in peritoneal macrophage cells at concentration of 100 µg/L. Molecular docking suggested that the most active compounds 1 and 2 can be positioned within the active sites of COX-2 at Arg121 & Tyr356 similar to ibuprofen (Arg-120, Glu-524, and Tyr-355). The compound 3–COX-2 complex generated by docking revealed intricate interactions with a COX-2 channel. Conclusion: These findings suggest that compounds 1-3 exhibited good antioxidant, antiulcer, anti-inflammatory activity and safe on liver enzymes in rats.

Objective: The present study was conducted to determine the hepatoprotective potentials of methanol s extracts of Tephrosia villosa leaves against thioacetamide (TAA) induced liver damage in rats. Methodology: The acute oral toxicity study was conducted as per OECD guidelines, and the extract was proved to be safe up to the dose of 2000 mg/kg. The total duration of the study was 21 days, and animals were divided into six groups. Hepatotoxicity was induced in the animals of all groups except normal control by single dose administration of TAA (100 mg/kg) at 1st day of the study followed by animals were treated daily with standard drug silymarin and methanol extract of T. villosa (100 mg/kg, 200 mg/kg and 400 mg/kg) to respective groups for 21 days. Variations in biochemical parameters such as alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, total bilirubin, direct bilirubin, albumin, total protein, ions and others parameters such as clotting time and weight of the liver were considered to determine beneficial effect of the extract. At the end of the study liver samples were collected and subjected to histopathological evaluation. Results: In control animals treated with TAA alone, there were variations in the above mentioned parameters. However in the animals treated with methanol extract and standard drug silymarin, all the parameters were normal possibly due to their beneficial property in protecting the liver against TAA induced hepatotoxicity. Conclusion: The results obtained in the above study suggesting that, the methanol extract of T. villosa possess significant hepatoprotective activity.

Liver plays an important role in maintaining the biological equilibrium of vertebrates. Liver diseases are a major worldwide health problem with high endemicity in developing countries. They are mainly caused by chemicals and some drugs when taken in very high doses. Despite advances in modern medicine, there is no effective drug available that stimulates liver function, offer protection to the liver from damage or help to regenerate hepatic cells. There is urgent need, therefore, for effective drugs to replace/supplement those in current use. The plant kingdom is undoubtedly valuable as a source of new medicinal agents. The main aim of any medication in the treatment of liver disorders is to prevent degeneration of hepatocytes and associated metabolic abnormalities and promote regeneration of hepatic cells. In present study the hepatoprotective activity of Cynodon dactylon extracts was evaluated in rifampicin induced liver toxicity by biochemical parameters like SGPT, SGOT, ALP, BIT and by histopathological study. Acute administration of rifampicin produced marked elevation of the serum levels of the above parameters compared to that of the control group. Treatment with ethanolic and aqueous extracts of Cynodon dactylon leaves at doses of 200 and 400 mg/kg produces significant prevention in rifampicin induced rise of the above parameters. Silymarin at 100 mg/kg body weight significantly prevented such rise in study. The effect of Cynodon dactylon leaves extracts was found possess promising hepatoprotective activity. Further studies in other species and on other parameter would throw more light on this plant.
