Potential and Possible Therapeutic Effects of Melatonin on SARS-CoV-2 Infection.

ABSTRACT: The absence of effective drugs for COVID-19 prevention and treatment requires the search for new candidates among approved medicines. Fundamental studies and clinical observations allow us to approach an understanding of the mechanisms of damage and protection from exposure to SARS-CoV-2, to identify possible points of application for pharmacological interventions. In this review we presented studies on the anti-inflammatory, antioxidant, and immunotropic properties of melatonin. We have attempted to present scientifically proven mechanisms of action for the potential therapeutic use of melatonin during SARS-CoV-2 infection. A wide range of pharmacological properties allows its inclusion as an effective addition to the methods of prevention and treatment of COVID-19.

Project description:BackgroundThe SARS-Cov-2(severe acute respiratory syndrome coronavirus 2) infection affecting human populations worldwide is now a very concerning issue considering the morbidity and mortality rates. Despite several measures followed by the medical fraternity and general public, there is no resolution. Therapeutic measures to tackle the infection have been based on researching new designer drug molecules that could prevent viral entry into the human host. Melatonin has been tried as an adjuvant in the management of COVID 19(coronavirus disease) illness but its specific antiviral role has not been investigated. Objectives: The objectives of the present study were to conduct an in-silico analysis to investigate if melatonin and related drugs namely ramelteon and agomelatine could be used as antiviral agents in SARS-CoV-2 infection based on their binding to the SARS-CoV-2 receptor binding site (RBD) and Angiotensin-converting enzyme 2 (ACE 2).MethodsFor docking studies (Pdb Id 1M0J), the SARS-CoV-2 spike protein receptor-binding domain (RBD) crystal structure which was ACE2 cell receptor bounded was employed. From the PubChem database, the three-dimensional configuration of the ligands melatonin, ramelteon, and agomelatine was retrieved, and conceptual density functional theory (CDFT) was performed to determine molecular descriptors. Charges were added and optimized with the universal force field to prepare the ligands for the process of docking. For facilitation of readability by the AutoDock software conversion to PDBQT(Protein Data Bank, Partial Charge (Q), & Atom Type (T)) format was performed. AutoDock version 4.2.6 docking program and AutoDock Tools (ADT) version 1.5.6 were used for molecular docking. Desmond, a Package of Schrödinger LLC was used to simulate molecular dynamics for hundred nanoseconds using.ResultsData from the present study reveal that melatonin, ramelteon, and agomelatine demonstrate significant binding with SARS-CoV-2 RBD and ACE 2 demonstrating the fact that they can strongly prevent viral entry into the host cells through dual binding effects. However, Ramelteon was found to be the most superior amongst the 3 drugs analyzed in its antiviral properties against SARS-CoV-2.ConclusionResults advocate further research in exploring the potential therapeutic applications of melatonin, ramelteon, and agomelatine for the management of SARS-CoV-2 infection.
