Fig. 4. Binding models of the identified inhibitors 7–13 and 5 in the binding pocket of LDHA. (A) Compound 5 was docked into the binding pocket of LDHA. (B–H) Compounds 7–13 were docked into the active site of LDHA. The amino acid residues and the inhibitors were shown as stick models, and H-bonds were shown as yellow dashed lines.
