Background and Objectives: By the end of 2019, a novel human coronavirus outbreak started in Wuhan and spread to the world becoming a global pandemic, patients were diagnosed with severe respiratory syndrome Studies have shown that SARS-CoV2 interact with angiotensin-converting enzyme 2 (ACE2), its host cell receptor, by its Spike Glycoprotein The aim of this study is to prevent this interaction by inhibiting Spike glycoprotein Materials and Methods: The interaction of the Spike Glycoprotein of SARS-COV-2 extracted from protein data bank (PDCode: 6VSand 6LZG) with 10 different ferrocene derivatives ligands were investigated by performing docking studies using Autodock Tools 4 2 software Results: The obtained results showed that N-ferrocenyl-methyl-3-nitroaniline was the best inhibitor ligand interacted with both proteins of coronavirus with the free binding energy equal to -5 38 and -6 65 Kcal/mol for 6VSand 6LZG respectively with binding constant values equal to 8 7 × 10 su3 /suand 72 72× 10 su3 /surespectively Calculations revealed that the dominated mode of interaction for all the studied ligands with COVID-19 was the electrostatic mode via at least one H-bond and more than two hydrophobic Pi-Alkyl Bonds Conclusion: Generally, the results indicated the existence of strong interactions between ligands and spike glycoprotein which prevent the virus to interact to ACE2 receptors
