Currently, there is no specific treatment to cure COVID-19. Many medicinal plants have antiviral, antioxidant, antibacterial, antifungal, anticancer, wound healing etc. Therefore, the aim of the current study was to screen for potent inhibitors of N-terminal domain (NTD) of nucleocapsid phosphoproteinof SARS-CoV-2. The structure of NTD of RNA binding domain of nucleocapsid phosphoprotein of SARS coronavirus 2 was retrieved from the Protein Data Bank (PDB 6VYO)and the structures of 100 different phytocompoundswere retrieved from Pubchem. The receptor protein and ligands were prepared using Schrodinger’s Protein Preparation Wizard. Molecular docking was done by using the Schrodinger’s maestro 12.0 software. Drug likeness and toxicity of active phytocompounds was predicted by using Swiss adme, admetSAR and protox II online servers. We have identified three potential active sites (named as A, B, C) on receptor protein for efficient binding of the phytocompounds. We found that, among 100 phytocompounds, emodin, aloe-emodin, anthrarufin, alizarine, and dantron of Rheum emodi showed good binding affinity at all the three active sites of RNA binding domain of nucleocapsid phosphoprotein of COVID-19.The binding energies of emodin, aloe-emodin, anthrarufin, alizarine, and dantron were -8.299 , -8.508, -8.456, -8.441, and -8.322 Kcal mol-1 respectively (site A), -7.714, -6.433, -6.354, -6.598, and -6.99 Kcal mol-1 respectively (site B), and -8.299, 8.508, 8.538, 8.841, and 8.322 Kcal mol-1 respectively (site C).All the active phytocompounds follows the drug likeness properties, non-carcinogenic, and non-toxic. Theses phytocompounds (alone or in combination) could be developed into effective therapy against COVID-19.
