| Summary: | Gout is a metabolic disease that seriously affects people's health. Polydatin, a stilbene compound isolated from Polygonum cuspidatum, has attracted much attention because of its rich biological activity and high safety. This study aimed to investigate the therapeutic effect and mechanism of polydatin on hyperuricemia (HUA) combined with gouty arthritis (GA). The results showed that polydatin reduced the levels of uric acid and inflammatory cytokines, indicating that polydatin had the effect of reducing uric acid and anti-GA. Then the inhibitors of ABCG2, NLRP3 inflammasome and NF-κB pathway (Ko143, MCC950 and QNZ) were used to demonstrate that polydatin played a role in reducing uric acid and anti-GA via regulating urate transporters, NLRP3 inflammasome and NF-κB pathway. Taken together, these results provided evidence that polydatin might be used as a potential functional ingredient for the synchronous treatment of HUA and GA.
