Xanthine oxidase (XO) is a potential target for gout disease experiments on animals and humans. Using molecular docking technique to search anti-XO compounds from Vietnamese medicinal plants, we discovered that numerous Uvaria cordata (Dunal) Alston (Annonaceae family) showed this activity. Among these, cordauvarin A exhibited the strongest binding affinity (−8.8 kcal/mol) XO through interaction with 5 amino acids (eg Gln-1194, Ala-1079, Ser-1080, Met-1038, Arg-912) of protein.
