Abstract
AbstractCoronavirus disease‐19 (COVID‐19) is the global health emergency caused by SARS‐CoV‐2. Upon infection, antigenic determinants of the virus trigger massive production of proinflammatory/pyroptosis‐associated proteins, resulting in cytokine storm, tissue damage, and multiorgan failure. Therefore, these proinflammatory/pyroptosis‐associated mediators are promising therapeutic targets to combat COVID‐19. Epicatechin gallate (ECG) is a polyphenol found in green tea. It has antioxidative and anti‐inflammatory properties. Hence, in the present study, ECG was selected to explore its binding potential for inflammatory mediators such as interleukins, interferon‐γ (IFNγ), and tumor necrosis factor‐α (TNF‐α), along with their native receptors. In addition, the interacting potential of ECG with pyroptosis‐associated proteins, viz. caspases and BAX has also been investigated. Molecular docking analysis has revealed that ECG interacts with interleukins, IFNγ, TNF‐α, cytokine receptors, caspase‐1/4/11, and BAX with significant binding affinity. Several amino acid residues of these mediators were blocked by ECG through stable hydrogen bonds and hydrophobic contacts. ECG interacted with caspase‐11, BAX, and TNF‐R1 with better binding affinities. Therefore, the present in silico study indicates that ECG could be a potential drug to subvert cytokine storm and pyroptosis during COVID‐19.
