In Silico study showing vitamin D binding with Mpro of SARS-CoV-2. Among the compounds tested, vitamin D had the highest potential interaction in terms of total H-bond, van der Waal, torsional, and desolvation energy. Authors recommend adding vitamin D to COVID-19 treatment protocols.

In this study, vitamin D has shown greater efficacy of binding with M pro of COVID-19 compared to the recently recommended drugs. The docking study was simulated to streamline interaction effects of Vitamin D, Remdesivir, Chloroquine, Hydroxychloroquine, Aspirin, and Azithromycin complexes with the active site of M pro . Vitamin D is found to have the highest potential interaction in terms of total H-bond, van der Waal, torsional, and desolvation energy which were the lowest among all the selected drugs. The hydroxyl group of vitamin D and the thiol group of M pro cysteine had played a leading role in increasing Vitamin D binding and stability with the M pro pocket by contribution to the inception of three hydrogen bonds. The study recommend that vitamin D can be added to the COVID-19 treatment protocol, which may have the desired effect on viral replication inhibition and decreases mortality.
