Quercetin IC50 and CC50. (A) IC50 of quercetin inhibition of syncytialization of HEK293(S + ACE2) based on decrease of GFP fluorescence. (B) CC50 of quercetin on HEK293 cells as determined using the MTS viability assay. (C) IC50 of quercetin inhibition of in vitro binding of ACE2 to Spike RBD. (D). IC50 of anti-Spike antibody inhibition of in vitro binding of ACE2 to Spike RBD. Results are from 3 separate experiments and are expressed as means ± SD
