Background:
HCV has become a leading cause of liver cirrhosis and hepatocellular carcinoma and is a major health concern worldwide. To date, there is no vaccine available in the market to tackle this disease, therefore there is a strong need to develop antiviral compounds that can target all genotypes of HCV with the same efficiency. Medicinal plants have low cost and are less toxic therefore, extracts of medicinal plants can serve as important antiviral agents against HCV. This study was designed to screen phytochemicals of Accacia nilotica to find a potent drug candidate that can inhibit HCV infection effectively.
Results:
Docking of NS3/4A protease and Flavonoids of Accacia nilotica revealed that most of the flavonoids bound deeply with the active site of NS3/4A protease. Compound 01 showed a high ranking on docking score. All other compounds also showed reliable docking scores and had interactions with the binding cavity of NS3/4A protease, suggesting them as a potent drug candidate to block HCV replication.
Conclusion:
To recognize binding interactions of Accacia nilotica phytochemicals with NS3/4A protease, molecular docking was performed to find potential inhibitor against NS3/4A protease of HCV. After post docking analysis, important interactions were found between active compounds and active site of NS3/4A protease. It can be concluded from the study that phytochemicals of Accacia nilotica may serve as a potential drug candidate with relatively simple structural changes against HCV NS3/4A protease.
Insights
Phytochemicals from Acacia nilotica show promise as antiviral agents against Hepatitis C virus (HCV). Molecular docking suggests these compounds can effectively inhibit the NS3/4A protease, a key target for HCV drug development.
Area of Science:
- * Phytochemistry and Molecular Modeling
- * Hepatitis C Virus (HCV) Research
Background:
- * Hepatitis C virus (HCV) is a significant global health issue, causing liver cirrhosis and cancer, with no current vaccine.
- * There is a critical need for broad-spectrum antiviral compounds effective against all HCV genotypes.
- * Medicinal plants, like Acacia nilotica, offer a cost-effective and less toxic source for potential antiviral drug discovery.
Purpose of the Study:
- * To screen Acacia nilotica phytochemicals for potent drug candidates against HCV.
- * To investigate the inhibitory potential of Acacia nilotica compounds against the HCV NS3/4A protease.
Main Methods:
- * Molecular docking simulations were employed to analyze the binding interactions between Acacia nilotica flavonoids and the HCV NS3/4A protease active site.
- * Post-docking analysis was conducted to evaluate binding scores and identify key interactions within the protease's binding cavity.
Main Results:
- * Most screened flavonoids from Acacia nilotica demonstrated deep binding within the active site of the NS3/4A protease.
- * Compound 01 exhibited a high docking score, with other compounds also showing significant binding affinity.
- * These interactions suggest the potential of these flavonoids to effectively block HCV replication.
Conclusions:
- * Phytochemicals from Acacia nilotica show significant potential as inhibitors of the HCV NS3/4A protease.
- * Molecular docking analysis revealed favorable binding interactions between these compounds and the viral protease.
- * Acacia nilotica phytochemicals may serve as valuable lead compounds for developing novel anti-HCV therapeutics with potential for structural modification.
