33479401-10	2021	Protein-protein interaction studies in presence of curcumin or catechin also corroborate the above findings suggesting the efficacy of these two polyphenols in hindering the formation of S Protein-ACE2 complex.	Polyphenols	145-156	surface glycoprotein	Severe acute respiratory syndrome coronavirus 2	187-188	
33149560-8	2020	However, 4 polyphenols such as epigallocatechin gallate (EGCG), homoeriodictyol, isorhamnetin, and curcumin interact, in addition to the Spike protein and its binding sites in GRP78, with the ATPase domain of GRP78.	Polyphenols	11-22	surface glycoprotein	Severe acute respiratory syndrome coronavirus 2	137-142	
34803452-5	2021	The binding energy values of these polyphenols to the SARS-CoV-2 spike and ACE-2 protein were calculated separately with a molecular docking study using the AutoDock 4.2.6 program.	Polyphenols	35-46	surface glycoprotein	Severe acute respiratory syndrome coronavirus 2	65-70	
34138966-5	2021	Here, we provide experimental evidence that, among 56 tested polyphenols, including plant extracts, brazilin, theaflavin-3,3"-digallate, and curcumin displayed the highest binding with the receptor-binding domain of spike protein, inhibiting viral attachment to the human angiotensin-converting enzyme 2 receptor, and thus cellular entry of pseudo-typed SARS-CoV-2 virions.	Polyphenols	61-72	surface glycoprotein	Severe acute respiratory syndrome coronavirus 2	216-221
