Abstract:

With the continuous improvement of living standards, the incidence of gout is increasing rapidly, and it is becoming more common among younger individuals. Xanthine oxidase (XO) is a crucial target for treating gout, as inhibiting XO can effectively reduce the production of uric acid in the body and alleviate gout symptoms. In the present study, three potential XO inhibitors were identified through virtual screening and validated using surface plasmon resonance (SPR). Among these inhibitors, floxuridine exhibited the strongest binding activity at 0.35 μM, compared with 0.76 μM for the positive drug allopurinol. Molecular dynamics simulations were conducted to examine the binding pattern of these compounds with XO. It is noteworthy that all three compounds are already approved as marketed drugs and have established safety profiles, indicating their potential as effective XO inhibitors.
