Abstract
BACKGROUND
Phytochemicals and their derivatives are promising target drugs for various ailments and have served as therapeutic agents for several decades. Using in vivo and in vitro models and molecular docking, this study investigated the pharmacological potential of a flavonoid-rich fraction of the ethanolic extract of Sesbania grandiflora (SG).
OBJECTIVES
This research aimed to determine whether flavonoid-rich whole-plant extracts of SGs have any cytoprotective or in vivo hepatoprotective effects. Additionally, the study was intended to elucidate the molecular connections between the discovered flavonoid flavonols and PPARα target proteins linked to liver problems, for which an in silico molecular docking investigation was performed.
MATERIALS AND METHODS
To separate the flavonoid components, the entire Sesbania grandiflora plant was first extracted using ethanol as a solvent by soxhlet extraction. The resulting ethanolic extract was then fractionated. The cytoprotective and hepatoprotective properties were evaluated via in vitro and in vivo experiments. SGOT, SGPT, triglyceride, bilirubin, and total protein levels were used to evaluate hepatotoxicity in animal models. In vitro studies on Hepatocellular Carcinoma G2 (HepG2) cell lines have examined their cytotoxic effects and antioxidant activity. The most promising flavonoid-flavanol compounds were identified by conducting molecular docking studies against PPARα target protein (PDB ID: 3VI8) using MOE software.
RESULTS
In vivo, the serum levels of SGOT, SGPT, total triglyceride and total bilirubin were measured in experimental animals treated with the flavonoid-rich ethanolic extract of SG. Significant reductions in the levels of these hepatic injury markers were observed, indicating the hepatoprotective potential of the extract. Elevated levels of liver biomarkers in the untreated group indicated liver injury or dysfunction. The treated groups showed significant restoration of these biomarkers, suggesting the hepatoprotective potential of SG. The IC50 value for the total flavonoid content of SG was 190.28 μg/ml, indicating its safety in inhibiting HepG2 cell growth. Flavonoid treatment decreased cell viability but did not affect antioxidant parameters in hepatocytes. In addition, SG restored the damaged hepatocyte architecture. Molecular docking studies revealed the binding affinities of flavonoids for PPARα. These findings suggest that a promising lead candidate for the development of therapeutic medicines against anti-TB drug-induced hepatotoxicity has been identified.
CONCLUSION
Our findings demonstrate the hepatoprotective potential of the flavonoid-rich fraction of Sesbania grandiflora both in vivo and in vitro. This study provides valuable insights into its mechanism of action, highlighting its promising therapeutic application in the management of liver disorders. This study highlights the hepatoprotective and cytoprotective potential of the total flavonoid-rich fraction of SG.
