Fifty - three flavonoids were docked to the homology - modeled thioredoxin reductase (TrxR) of Plasmodium faciparum using the AUTODOCK software. Docking energies were calculated and the binding sites of TrxR were located in order to determine the most potent inhibitors. Among the flavonoids, erycristagallin had the most negative free binding energy (-16.54 ± 0.46 kcaVmol) while mucronulatol had the least negative free binding energy (-8.89 '0.15 kcaVmol).

Fifty-one ligands were found to bind to the primary binding site predicted by the Q — site finder. Phaseollidin and isosophoranone bind to sites 1 and 2 predicted by the Q — site finder. The primary binding site contains the redox active center in Cys — 88 and Cys 93.
