Fig. 5From: Potential inhibitors for blocking the interaction of the coronavirus SARS-CoV-2 spike protein and its host cell receptor ACE2Molecular Docking of TS984 with S protein/ACE2 complex. A 2D Structure of Tannic acid, TS-984, TS-1276 and Emodin. B Predicting the interaction mechanism of the 9-methoxycanthin-6-one and the S protein/ACE2 complex. The yellow sticks represent the ligand 9-methoxycanthin-6-one, the green and blue sticks represent the important residues within 5Â Ã… of the ligand, the red dotted line represents the H-bond interaction located in the 9-methoxycanthin-6-one and the S protein/ACE2 complexBack to article page
