Polyphenols 24-35 NEWENTRY Severe acute respiratory syndrome-related coronavirus 86-90 32568613-5 2021 In order to find potent Mpro inhibitors, we have selected eight polyphenols from green tea, as these are already known to exert antiviral activity against many RNA viruses. Polyphenols 64-75 NEWENTRY Severe acute respiratory syndrome-related coronavirus 24-28 32568613-6 2021 We have elucidated the binding affinities and binding modes between these polyphenols including a well-known Mpro inhibitor N3 (having binding affinity -7.0 kcal/mol) and Mpro using molecular docking studies. Polyphenols 74-85 NEWENTRY Severe acute respiratory syndrome-related coronavirus 109-113 32568613-6 2021 We have elucidated the binding affinities and binding modes between these polyphenols including a well-known Mpro inhibitor N3 (having binding affinity -7.0 kcal/mol) and Mpro using molecular docking studies. Polyphenols 74-85 NEWENTRY Severe acute respiratory syndrome-related coronavirus 171-175 32568613-7 2021 All eight polyphenols exhibit good binding affinity toward Mpro (-7.1 to -9.0 kcal/mol). Polyphenols 10-21 NEWENTRY Severe acute respiratory syndrome-related coronavirus 59-63 32568613-8 2021 However, only three polyphenols (epigallocatechin gallate, epicatechingallate and gallocatechin-3-gallate) interact strongly with one or both catalytic residues (His41 and Cys145) of Mpro. Polyphenols 20-31 NEWENTRY Severe acute respiratory syndrome-related coronavirus 183-187 32568613-8 2021 However, only three polyphenols (epigallocatechin gallate, epicatechingallate and gallocatechin-3-gallate) interact strongly with one or both catalytic residues (His41 and Cys145) of Mpro. epigallocatechin gallate 33-57 NEWENTRY Severe acute respiratory syndrome-related coronavirus 183-187 32568613-8 2021 However, only three polyphenols (epigallocatechin gallate, epicatechingallate and gallocatechin-3-gallate) interact strongly with one or both catalytic residues (His41 and Cys145) of Mpro. epicatechin gallate 59-77 NEWENTRY Severe acute respiratory syndrome-related coronavirus 183-187 32568613-8 2021 However, only three polyphenols (epigallocatechin gallate, epicatechingallate and gallocatechin-3-gallate) interact strongly with one or both catalytic residues (His41 and Cys145) of Mpro. gallocatechin gallate 82-105 NEWENTRY Severe acute respiratory syndrome-related coronavirus 183-187 32568613-9 2021 Molecular dynamics simulations (100 ns) on these three Mpro-polyphenol systems further reveal that these complexes are highly stable, experience less conformational fluctuations and share similar degree of compactness. Polyphenols 60-70 NEWENTRY Severe acute respiratory syndrome-related coronavirus 55-59 32568613-10 2021 Estimation of total number of intermolecular H-bond and MM-GBSA analysis affirm the stability of these three Mpro-polyphenol complexes. Polyphenols 114-124 NEWENTRY Severe acute respiratory syndrome-related coronavirus 109-113 32568613-12 2021 Altogether, our study shows that these three polyphenols can be used as potential inhibitors against SARS CoV-2 Mpro and are promising drug candidates for COVID-19 treatment.Communicated by Ramaswamy H.
