The rationale of repurposing current classes of antiviral small molecule therapeutics against SARS-CoV-2 infection has been expected to accelerate the tedious and expensive drug development approach. Even though Remdesivir has been lately approved to become the first treatment option for certain groups of COVID-19 sufferers, combinatory therapy with possible antiviral drugs might be necessary to enhance the efficacy in different populations. Hence, a extensive list of investigational antimicrobial drug compounds for instance Favipiravir, Fidaxomicin, Galidesivir, GC376, Ribavirin, Rifabutin, and Umifenovir were computationally evaluated in this study. We performed in silico docking and molecular dynamics simulation around the chosen small molecules against RNA-dependent RNA polymerase, that is one of many key target proteins of SARSCoV-2, employing AutoDock and GROMACS. Interestingly, our results revealed that the macrocyclic antibiotic, Fidaxomicin, possesses the highest binding affinity with all the lowest power value of -8.97 kcal/mol binding to the same active web sites of RdRp. GC376, Rifabutin, Umifenovir and Remdesivir have been identified as the subsequent greatest compounds. Thus, the above-mentioned compounds could be deemed good leads for additional preclinical and clinical experimentations as potentially efficient antiviral inhibitors for mixture therapies against SARS-CoV-2. 2022 The Author(s).

Rajajagadeesan et al.Journal of Infection and Public Health 15 (2022) 1180Introduction The COVID-19 pandemic has brought on unprecedented healthcare emergencies all across the globe, which demands the speedy discovery of efficacious and deployable drugs against SARS-CoV-2 virus [1,2]. As of Oct 2020, US FDA has authorized the nucleoside antiviral drug, Remdesivir (also called Veklury), for treating particular groups (adult and pediatric) of COVID-19 individuals, who’re of 12 years of age or older and weighing at the least 40 kg, requiring hospitalization [3].
