Abstract
SARS-COV-2 stands as the source of the most catastrophic pandemic of this century, known as COVID-19. In this regard, we explored the effects of five Pistacia sp. active ingredients on the most crucial targets of SARS-COV-2, including 3CLpro, PLpro, RdRp, helicase, NSP15, and E protein. The results of molecular docking determined 1,2,3,4,6-pentagalloyl glucose (PG) as the most effective compound of Pistacia sp, which also confirmed its excellent binding affinities and stable interactions with helicase (−10.76 kcal/mol), RdRp (−10.19 kcal/mol), E protein (−9.51 kcal/mol), and 3CLpro (−9.47 kcal/mol). Furthermore, MD simulation was conducted to investigate the stability of all complexes throughout a 100 ns. In contrast to PLpro and NSP15, the analyses of Lennard-Jones potential, RMSDas, PCA, and SASA verified the ability of PG in forming stable and adequate interactions with RdRp, helicase, 3CLpro, and E protein due to standing as an effective inhibitor among the six targets, these data proposed the capability of PG, the most important compound of Pistacia sp., in inducing antiviral, anti-inflammatory, and antioxidant impacts on RdRp, helicase, 3CLpro, and E protein. Therefore, the possibility of inhibiting the replication and transcription processes and viral pathogenesis of SARS-COV-2 may be facilitated through the application of PG.
