Hesperidin, as a flavonone, is recognized as promising anti-inflammatory, antioxidant, and anticancer agent. Its poor bioavailability is crucial bottleneck for therapeutic efficacy. To enhance the stability and bioactive potentials, hesperidin-PLGA-Poloxamer 407 was successfully prepared to minimize or overcome problems associated with hesperidin absorption. The characteristics of nanohesperidin were testing by in vitro dissolution study, XRD, FTIR, PSA and SEM. Antioxidant effects of nanohesperidin were studied. The structure-activity relationship analysis with antioxidant pharmacophore has been performed by using density functional theory method and quantum chemical calculations. The structural properties were investigated using Becke three-parameter hybrid exchange and the Lee-Yang-Parr correction functional methods. Nanohesperidin was found to decrease the H 2 O 2 activity-induced DNA instability. Blood compatibility on human erythrocytes was confirmed by haemolytic and in vitro toxicity assessments. The in vitro anticancer activity of nanohesperidin towards MCF-7 cells using various parameters was carried out. The nanohesperidin was found to exert cell growth arrest, activated DNA fragmentation and induced apoptotic cell death through caspase-3 and p53-dependent pathways. These findings showed that nanohesperidin play an important role in its anticancer effects, suggesting might be used for clinical trials and can represent driving formulation for novel chemotherapeutic agents.
Hesperidin is one of the flavonoids from citrus peels and it recognized to possess various biological activities such as, anti-inflammatory, anti-carcinogenic, antioxidant and antimicrobial potentials. The present investigation studies the immunological adjuvant influence of hesperidin nanoparticles. Hesperidin nanoparticles were prepared by nano-precipitation technique by using Poly (D, L-lactic-co-glycolic acid) (PLGA) polymer and Poloxamer 407 was used as a stabilizer. This method was used because of their advantage of low setup cost and simplicity. Hesperidin nanoparticles were characterized by fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD) and particle size analysis (PSA) analytical methods. The effect of hesperidin nanoparticles was higher than the effect of pure hesperidin, and there was an obvious increase in phagocytosis index (PI 82%) of hesperidin nanoparticles when compared with pure hesperidin (PI 56%) and in comparison with the control samples (PI 22%). In conclusion we need further studies about if nano-hesperidin has therapeutic effects.
