摘要
Anxiety is an unpleasant state,which can critically decrease the quality of life is often accompanied by nervous behaviour and rumination.Niranthin is a lignan isolated from various Phyllanthus sources.The literature survey on niranthin highlights wide ranges of the therapeutic potentials.In a present study,based on our previous investigations,we evaluated pure,isolated and characterized niranthin as an anxiolytic agent.The niranthin[6-[(2R,3R)-3-[(3,4-dimethoxyphenyl)methyl]-4-methoxy-2-(methoxymethyl)butyl]-4-methoxy-1,3-benzodioxole]was purchased from commercial source and further subjected for assessment of its anxiolytic potentials using popular animal models including Elevated plus-maze model/test(EPM)and Light&Dark Exploration test(L&D).GABA-A receptor mediation was evaluated by pretreating the mice with the GABA-A receptor antagonist Flumazenil before the EPM task.Molecular docking simulation studies(pdb id:4COF)carried out by Vlife QSAR software showed that niranthin(docking score:−62.1714 kcal/mol)have shown comparatively best docking score compared to the standard drug Diazepam(docking score:−63.1568 kcal/mol).To conclude,Niranthin has probable potential in the management of anxiety disorder.Our in-silico and in-vivo analysis(indirectly)indicated the plausible role of GABA mediation for anxiolytic activity.Although,these studies are preliminary,future in depth experimental explorations will be required to use Niranthin as anti-anxiety drug in near future.
