Abstract
Background: Hepatitis B virus claims approximately 780000 human lives each year. Inadequate effectiveness and drug resistance has led to the search for more potent antivirals with minimal risk of resistance. Plant extract from Phyllanthus genus have long been used in traditional medicine as effective antiviral and hepatoprotective agents.
Objective: The present study aims to find the active principle of Phyllanthus and their mode of action against Hepatitis B Virus Reverse Transcriptase (HBV RT), a potential drug target of HBV infection. Methods: The 3D structure of HBV RT was modeled and its stability was assessed with a 50ns molecular dynamics simulation. Ninety-three phytochemicals were screened from Phyllanthus and used for docking study taking lamivudine as control drug. Results: Comparison of binding energy suggests that, lupeol acetate, a triterpene of P. niruri, P. reticulatus and P. urinaria showed highest binding energy for both native and M204V mutated HBV RT (-7.95 kcal/mol & -6.16 kcal/mol respectively) than the control drug lamivudine (-4.57 kcal/mol & -3.50 kcal/mol respectively). Subsequently, lupeol acetate was screened for in silico ADME/Tox property and result indicates good bioavailability without toxicity and can be treated as a candidate drug molecule. Conclusion: Further clinical testing may lead to the discovery of a novel HBV RT inhibitor.Keywords: Phyllanthus, lupeol acetate, Hepatitis B virus, molecular docking, molecular dynamics simulation, in silico ADME/Tox and Lamivudine.

Ayurvedic medicinal therapeutic approaches for inflammatory and neurodegenerative disorders
Usually, in our elderly population, neurodegenerative disorders occur due to neuron death. Alzheimer?s disease (AD) is an irreversible and progressive neurodegenerative disease. Dementia is the leading cause of AD, which affects about 30 million people worldwide. According to the World Alzheimer report 2018, a new case of dementia develops every ...read more
Recent Advances in Biotransformation of Bioactive Terpenoids using Aspergillus niger
Biotransformation is the reaction catalyzed by biological catalysts of either isolated enzymes or whole cell cultures of microorganisms. This process has been extensively applied in the conversion of bioactive terpenoids with high regio- and stereospecifity. This process has been also applied in the lead discovery and development. Aspergillus niger has ...read more
