Daidzein is a common isoflavone, having multiple biological effects such as anti-inflammation, anti-allergy, and anti-aging. α-Tocopherol is the tocopherol isoform with the highest vitamin E activity including anti-allergic activity and anti-cancer activity. Hesperetin is a flavone, which shows potent anti-inflammatory effects. These compounds have shortcomings, i.e., water-insolubility and poor absorption after oral administration. The glycosylation of bioactive compounds can enhance their water-solubility, physicochemical stability, intestinal absorption, and biological half-life, and improve their bio- and pharmacological properties. They were transformed by cultured Nicotiana tabacum cells to 7-β-glucoside and 7-β-gentiobioside of daidzein, and 3′- and 7-β-glucosides, 3′,7-β-diglucoside, and 7-β-gentiobioside of hesperetin. Daidzein and α-tocopherol were glycosylated by galactosylation with β-glucosidase to give 4′- and 7-β-galactosides of daidzein, which were new compounds, and α-tocopherol 6-β-galactoside. These nine glycosides showed higher anti-allergic activity, i.e., inhibitory activity toward histamine release from rat peritoneal mast cells, than their respective aglycones. In addition, these glycosides showed higher tyrosinase inhibitory activity than the corresponding aglycones. Glycosylation of daidzein, α-tocopherol, and hesperetin greatly improved their biological activities.

“Hesperetin is a natural flavanone compound, which mainly exists in lemons and oranges, and has potential antiviral and anticancer activities. In this study, hesperetin was used in a crayfish pathogen challenge to discover its effects on the innate immune system of invertebrates. The crayfish Procambarus clarkii was used as an experimental model and challenged with white spot syndrome virus (WSSV). Pathogen challenge experiments showed that hesperetin treatment significantly reduced the mortality caused by WSSV infection, while the VP28 copies of WSSV were also reduced. Quantitative reverse transcriptase polymerase chain reaction revealed that hesperetin increased the expression of several innate immune-related genes, including NF-kappaB and C-type lectin. Further analysis showed that hesperetin treatment plays a positive effects on three immune parameters like total hemocyte count, phenoloxidase and superoxide dismutase activity. Nevertheless, whether or not infected with WSSV, hesperetin treatment would significantly increase the hemocyte apoptosis rates in crayfish. These results indicated that hesperetin could regulate the innate immunity of crayfish, and delaying and reducing the mortality after WSSV challenge. Therefore, the present study provided novel insights into the potential therapeutic or preventive functions associated with hesperetin to regulate crayfish immunity and protect crayfish against WSSV infection, provide certain theoretical basis for production practice.

“A novel restricted access molecularly imprinted polymers (RAMIPs) fiber was developed for solid-phase microextraction (SPME) of hesperetin and its metabolites in livers of live rats in vivo. Hesperetin as the template, N-isopropylacrylamide as the functional monomer, ethylene glycol dimethyl acrylate as the crosslinker, 2,2-azobisisobutyonnitrile as initiator and bovine serum albumin as the restricted access material were applied in the preparation process. Scanning electron microscopy and Fourier transform infrared spectroscopy were applied to characterize the polymers. The adsorption experiments indicated that RAMIPs-SPME fibers performed high selective recognition property to hesperetin. The selectivity experiment indicated that the adsorption capacity and selectivity of RAMIPs-SPME fibers to hesperetin was higher than that of quercetin, luteolin and baicalein. Macromolecules elimination test showed RAMIPs-SPME fibers could eliminate 94.80%-98.96% of macromolecules, which indicated that RAMIPs-SPME fibers can be used to extract analytes directly from complex biological samples. Furthermore, RAMIPs-SPME sampling combined to ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was applied to capture and identify hesperetin and its metabolites in rat livers in vivo. Finally, hesperetin-7-O-glucuronide, hesperetin-3′-O-glucuronide, eriodictyol and homoeriodictyol were identified as the metabolites of hesperetin. In comparison with the MIPs fibers, commercial PDMS and DVB fibers, RAMIPs-SPME fibers possessed better exclusion effect to macromolecules and higher selectivity to hesperetin and its metabolites. The results demonstrated that the prepared RAMIPs-SPME fiber were proven to be effective tool for the selective adsorption and enrichment of hesperetin and its metabolites from the complex biological fluids.
