AB  - Drug resistance is a critical problem in health care that affects therapy outcomes and requires new approaches to drug
design. SARS-CoV-2 Mpro mutations are of concern as they can potentially reduce therapeutic efficacy. Viral infections are amongst the
many disorders for which nutraceuticals have been employed as an adjunct therapy. The aim of this study was to examine the potential
in vitro activity of L-arginine and vitamin C against SARS-CoV-2 Mpro. Methods: The Mpro inhibition assay was developed by cloning,
expression, purification, and characterization of Mpro. Selected compounds were then screened for protease inhibition. Results: Larginine
was found to be active against SARS-CoV-2 Mpro, while a vitamin C/L-arginine combination had a synergistic antiviral action
against Mpro. These findings confirm the results of our previous in silico repurposing study that showed L-arginine and vitamin C were
potential Mpro inhibitors. Moreover, they suggest a possible molecular mechanism to explain the beneficial effect of arginine in COVID
patients. Conclusions: The findings of the current study are important because they help to identify COVID-19 treatments that are
efficient, inexpensive, and have a favorable safety profile. The results of this study also suggest a possible adjuvant nutritional strategy
for COVID-19 that could be used in conjunction with pharmacological agents.

AB  - Finding an effective drug to prevent or treat COVID-19 is of utmost importance in tcurrent
pandemic. Since developing a new treatment takes a significant amount of time, drug repurposing
can be an effective option for achieving a rapid response. This study used a combined in silico virtual
screening protocol for candidate SARS-CoV-2 PLpro inhibitors. The Drugbank database was searched
first, using the Informational Spectrum Method for Small Molecules, followed by molecular docking.
Gramicidin D was selected as a peptide drug, showing the best in silico interaction profile with PLpro.
After the expression and purification of PLpro, gramicidin D was screened for protease inhibition
in vitro and was found to be active against PLpro. The current study’s findings are significant
because it is critical to identify COVID-19 therapies that are efficient, affordable, and have a favorable
safety profile.
