Hesperetin is a flavanone glycoside compound naturally occurring in the fruit peel of Citrusaurantium L. (Rutaceae). Previous studies revealed that hesperetin possesses various pharmacological effects, including anti-inflammation, anti-tumor, anti-oxidant and neuroprotective properties. Hesperetin derivative-14 (HD-14) is a derivative of hesperetin improved in water solubility and bioavailability. In this study, we indicated that HD-14 (2μM) significantly attenuated inflammation in LPS-treated RAW264.7 cells and had hepato-protective effects and anti-inflammatory effects (100mg/kg) on C57BL/6J mice with CCl4-induced acute liver injury...

Hesperetin has been suggested to be involved in bone strength. We aimed to investigate the effects of hesperetin on the osteogenic differentiation of human mesenchymal stem cells and its related mechanisms. We showed that hesperetin promoted osteogenic differentiation of human mesenchymal stem cells in vitro. It potentially exerts its effects via the ERK and Smad signaling pathways. Using a rat osteotomy model, we showed that human mesenchymal stem cells combined with a hesperetin/gelatin sponge scaffold resulted in accelerated fracture healing in vivo...

Chronic venous insufficiency is characterized by chronic reflux disorder of blood from the peripheral to the central vein, with subsequent venous hypertension and resulting changes in the skin. Traditionally, nonsurgical treatments relied on the use of compression therapy, and more recently a variety of flavonoids have been shown to have positive effects. There have also been developments of more effective drug delivery systems using various textiles and nanotechnology to provide new therapeutic options. Our objective was to use nanotechnology to develop a new formulation containing hesperetin (Hst), a substance not previously used in the treatment of chronic venous insufficiency, impregnated into textile fibers as a possible alternative treatment of venous diseases...

Ethylenediamine-modified β-cyclodextrin (Et-β-CD) was immobilized on aggregated silver nanoparticle (NP)-embedded silica NPs (SiO₂@Ag@Et-β-CD NPs) for the effective detection of flavonoids. Silica NPs were used as the template for embedding silver NPs to create hot spots and enhance surface-enhanced Raman scattering (SERS) signals. Et-β-CD was immobilized on Ag NPs to capture flavonoids via host-guest inclusion complex formation, as indicated by enhanced ultraviolet absorption spectra. The resulting SiO₂@Ag@Et-β-CD NPs were used as the SERS substrate for detecting flavonoids, such as hesperetin, naringenin, quercetin, and luteolin...

The α-glucosidase inhibitor is of interest to researchers due to its association with type-2 diabetes treatment. Hesperetin is a flavonoid with natural antioxidant properties. This paper presents an evaluation on the effects of hesperetin on α-glucosidase via inhibitory kinetics using a Molecular Dynamics (MD) simulation integration method. Due to the antioxidant properties of hesperetin, it reversibly inhibits α-glucosidase in a slope-parabolic mixed-type manner (IC50=0.38±0.05mM; Kslope=0.23±0.01mM), accompanied by tertiary structural changes...
