Reported HA binding modes for arbidol and TBHQ. (A) Vertical view of the crystal structure of H3 HA protein in complex with arbidol (in magenta) and TBHQ (in yellow). The binding pose of TBHQ (from PDB entry: 3EYM) was superimposed onto the arbidol‐H3 HA cocrystal structure (PDB entry:5T6N). (B) Top view of the crystal structure of H3 HA protein in complex with arbidol and TBHQ. (C) The binding mode of TBHQ in PDB 3EYM crystal structure. (D) The binding mode of arbidol in PDB 5T6N crystal structure. The HA1 subunits of protomer 1 and 2 are colored in blue, and the HA2 subunits are in orange. TBHQ is colored in yellow and arbidol is magenta, in structure of ball and stick.
