ABSTRACT Hyperuricemia (HUA) is one of main risk factors for liver injury, and xanthine oxidase (XOD) an important target HUA‐induced injury. As a typical natural active ingredient, naringenin (NAR) has been confirmed the good therapeutic effect on variety diseases. However, studies NAR ameliorating injury have not reported. Therefore, we evaluated bioactivity in investigated related molecular mechanisms. The inhibitory activity type XOD was by enzymatic reactions kinetic analyses, docking showed that able to bind tightly XOD. In vivo ameliorated function while being inhibit activity. alleviated oxidative stress caused excess reactive oxygen species through antioxidant At same time, exerted anti‐inflammatory regulating levels inflammatory factors. results suggested interact with Keap1 AMPK exhibit effects.

Background: Obesity is a multifactorial disease with detrimental effects on health and quality of life; unregulated satiety plays crucial role in food intake obesity development. Naringenin (NAR) has shown beneficial lipid carbohydrate metabolism, although its impact adiposity remains unclear. This study reports Western diet (WD)-induced model rats, wherein 100 mg/kg NAR was administered as an anti-obesity agent for 8 weeks; oxidative stress, profile, biomarkers were then studied, well silico interaction between cholecystokinin (CCK) ghrelin receptors. Results: supplementation resulted significant decrease retroperitoneal adipose tissue liver weight, compared to the untreated WD group (p < 0.05), potentially associated decreased feed efficiency. also inhibited development dyslipidemia, particularly by reducing serum triglycerides 0.05). increased CCK levels basal group, effect that abolished 0.05); likewise, no changes determined > In data shows capable interacting receptors, which suggests potential it modulate hunger/satiety signaling them. Conclusions: We conclude anti-obesogenic may regulate levels, further research still needed.

ABSTRACT Naringenin, a flavonoid widely present in citrus fruits, has garnered considerable attention due to its diverse biological activities and health‐promoting benefits. As research on naringenin advances, the application scope of significantly expanded. This paper provides systematic overview production synthesis methods naringenin, focusing especially green extraction techniques strategies for constructing microbial metabolic engineering. Naringenin not only achieves including antioxidant, antiinflammatory, glucolipid metabolism regulation through multiple mechanisms but also modulates balance gut microbiota, thereby mediating synergistic health effects via host–microbial axis. Given low oral bioavailability various nanodelivery systems have been developed improve bioavailability. Meanwhile, molecular simulation elucidate binding conformation characteristics with receptors at level, providing novel insights into action. In conclusion, this review seeks offer theoretical basis future directions further naringenin.
