Evaluation of the Dual Effects of Antiviral Drugs on SARS-CoV-2 Receptors and the ACE2 Receptor Using Structure-Based Virtual Screening and Molecular Dynamics Simulation

This study explores the exciting world of drug repurposing, investigating the potential of existing, FDA-approved antiviral drugs to combat the SARS-CoV-2 virus, the cause of COVID-19. The study utilizes in silico medicine, which involves using computer simulations to screen potential drug candidates. The researchers specifically focus on identifying drugs that exhibit dual inhibitory activity, meaning they can target multiple proteins involved in the virus's lifecycle. The study's goal is to identify FDA-approved antiviral drugs that can effectively inhibit the SARS-CoV-2 virus by targeting multiple receptors, potentially leading to more effective treatment strategies.

The researchers employed a combination of molecular docking and molecular dynamics simulation to analyze the interactions of 70 FDA-approved antiviral drugs with various receptors of the SARS-CoV-2 virus, including the main protease, spike glycoprotein, and papain-like protease. They also investigated the interactions of these drugs with the ACE2 receptor of host cells, which the virus utilizes to enter cells. The researchers found that certain antiviral drugs, including Simeprevir, Maraviroc, and Saquinavir, exhibited strong binding affinities to multiple receptors of the SARS-CoV-2 virus and the ACE2 receptor. These drugs were identified as potential dual inhibitors, potentially offering a more effective approach to treating COVID-19.
