Natural chemical entities from Arisaema Genus might be a promising break-through against Japanese encephalitis virus infection: A molecular docking and dynamics approach.

概要
Japanese encephalitis virus (JEV) infection affects millions of population worldwide whose incidence is increasing year by year and currently, no specific drugs are available for its treatment. However, vaccines are available for its prevention but not effective against all the clinical isolates. Thus, there is an urgent need for new chemical entities or exploration of existing molecules for its treatment. In the current study, we have undertaken virtual ligand screening (VLS) method to screen out selected phytoconstituents of Genus Arisaema against various targets (NS5, NS3 helicase, and NS2B-NS3 protease) of JEVs which exhibits vital role in replication, infection cycle and host interaction by using molecular docking followed by molecular dynamics (MD) simulations. Screened natural chemical entities displayed good binding affinity as well as optimum stability towards NS5 and NS3 helicase. Further, the drug likeliness evaluated by Absorption, Distribution, Metabolism, Excretion and Toxicity (ADMET) analysis was found to be in the acceptable range. In conclusion, these natural chemical entities could be considered as promising candidates for the development of anti-JEV drugs. However, further investigation is required to confirm their exact role in JEV infection through in vitro and in vivo experiments.
