In Silico Molecular Docking and Molecular Dynamic Simulation Analysis of Phytochemicals From Indian Foods as Potential Inhibitors of SARS-CoV-2 RdRp and 3CLpro

Abstract

With the current pandemic of the novel coronavirus disease 2019 (COVID-19) in hand, researchers around the globe are dexterously working to find the best suitable drug candidates and overcome vaccination-related challenges, to achieve efficient control over the second surge of COVID-19. The medical consultants time and again have been reiterating the need to abide by the precautionary steps to prevent the spread of the coronavirus by maintaining social distancing when outside, sanitizing hands regularly, and wearing masks and gloves. They also suggest taking a good and hygienic meal so as to boost immunity. Indians have an inborn nature of using natural spices, food, and medicines in their daily lives. Indian researchers have paid heed to deploy compounds from natural sources to explore potential antiviral agents against COVID-19 as the chances of acquiring side effects are perceived as less, and the efficacy of phytochemicals from medicinal plants is sometimes greater when compared to their synthetic counterparts. In the present study, we performed an in silico molecular docking and molecular dynamic simulation analysis of screened phytochemicals from a comprehensive list of Ayurvedic herbs/functional foods that are present in natural food products against key receptor proteins of severe acute respiratory syndrome coronavirus 2. We found that Aegle marmelos, Vetiveria zizanoides, Moringaolifera, and Punica granatum have antiviral potential to prevent coronavirus infection in the populace.

RETRACTED: Artemisia Extracts and Artemisinin-Based Antimalarials for COVID-19 Management: Could These Be Effective Antivirals for COVID-19 Treatment?

“…By preventing virus entry and/or its replication or clearing of cells into which the virus has already entered, effective treatments with antivirals can help to slow the spread of a person's infection, potentially reducing the length and severity of symptoms. Thus, safe and effective antivirals responsible for restricting viral entry and/or disruption of the replication process are crucial to the pandemic response [5][6][7][8][9][10][11][12][13].…”

Targeting cyclin-dependent kinase 1 (CDK1) in cancer: molecular docking and dynamic simulations of potential CDK1 inhibitors

“…This mode of the in-silico approach has been utilized by various studies where the Molecular Docking and Molecular Dynamic Simulation analysis of the screened compounds have yielded the compounds having better properties than the already known compound [ 57 – 59 ]. For instance, the study done by Qazi et al used the same approach to analyze potent inhibitors of SARS-CoV-2 RdRp and 3CLpro [ 60 ].…”

Jiedu Huoxue Decoction for Cytokine Storm and Thrombosis in Severe COVID-19: A Combined Bioinformatics and Computational Chemistry Approach

“…At present, the drug targets against SARS-CoV-2 infection mainly include human protein ACE2, transmembrane protease serine 2 (TMPRSS2), and various SARS-CoV-2 proteins such as spike protein (S-protein), 3C-like protease (3CLpro), and papain-like protease (PLpro). 65,66 ACE2 is a crucial receptor for SARS-CoV-2 to invade the human body. 18 Small molecular compounds acting on ACE2 as inhibitors can block the binding of SARS-CoV-2 to ACE2.…”
