The interactions of eriodictyol and umbelliferone with TMPRSS2, ACE2, and SARS-CoV-2 S proteins. The predicted binding affinities of TMPRSS2 (PDB ID: 7MEQ) and the interface between ACE2 and S protein (PDB ID: 6M0J) with eriodictyol A and C and umbelliferone B and D were investigated by using BIOVIAÂ Discovery Studio. The rounds with black rings (right of C and D indicated the amino acid residues of S protein interacting with eriodictyol or umbelliferone
