33847382-4	2021	In this study, we observed that seabuckthorn and its flavonoid compounds quercetin and isorhamnetin were shown strong retention to ACE2 overexpression HEK293 (ACE2h ) cells by CMC analysis.	3-methylquercetin	87-99	angiotensin converting enzyme 2	Homo sapiens	131-135	
33847382-6	2021	Surface plasmon resonance assay proved the effect that isorhamnetin bound to the ACE2, and its affinity (KD value) was at the micromolar level, that was, 2.51 +- 0.68 muM.	3-methylquercetin	55-67	angiotensin converting enzyme 2	Homo sapiens	81-85	
33847382-7	2021	Viral entry studies in vitro indicated that isorhamnetin inhibited SARS-CoV-2 spike pseudotyped virus entering ACE2h cells.	3-methylquercetin	44-56	angiotensin converting enzyme 2	Homo sapiens	111-115
