Abstract
Nanoencapsulated bael fruit (Aegle marmelos L. Correa (Family: Rutaceae)) extracts reveal novel prospects in the development of dietary supplements with improved biological activities in the field of the food industry. The main objectives of this study were to prepare and characterize aqueous, ethanol, 50% ethanol, and 50% acetone extracts of bael fruit encapsulated alginate nanoparticles and investigate the effect of encapsulation on in vitro release of polyphenols, antidiabetic, antioxidant, and anti-inflammatory activities, and their stability. Bael fruit extracts encapsulated alginate nanoparticles were prepared using the ionic gelation method. Characterization, in vitro release profiles of polyphenols, determination of antidiabetic, anti-inflammatory, antioxidant activity, and accelerated stability were conducted. The results of the characterization confirmed the successful encapsulation of extracts of bael fruit in the alginate matrix. The aqueous extract of bael fruit encapsulated alginate nanoparticles exhibited a more controlled slow-release profile, accounting for 21.82% ± 1.17% and 48.14% ± 0.52% of polyphenols at solutions of pH 1.2 and pH 6.8, respectively. In general, the results of the bioactivity assessment suggested that nanoencapsulation could facilitate the enhancement of its antidiabetic, antioxidant, and anti-inflammatory properties. The results of thermogravimetric analysis and thin layer chromatography fingerprint showed the stability of aqueous bael fruit extract encapsulated alginate nanoparticles at 27 and 4°C over a month. In summary, the results of this study revealed the potency of nanoencapsulated aqueous extract of bael fruit to develop a dietary supplement with improved antidiabetic, antioxidant, and anti-inflammatory activities. PRACTICAL APPLICATION: The encapsulation of bael fruit extracts into a nanocarrier enhances bioactivities and promotes the controlled release of bioactive compounds. This could be useful in the future food industry, based on scientifically proven data, and inspire the market by means of the development of dietary supplements. Overall, the results would facilitate the formulation of novel commercially elegant nanoencapsulated dietary supplements with improved potential to manage a healthy life.

Front Pharmacol 2022; 13:812594. [PMID: 35370757 PMCID: PMC8971812 DOI: 10.3389/fphar.2022.812594] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Accepted: 02/21/2022] [Indexed: 11/29/2022] Open
Abstract
Adriamycin (ADR) has been utilized to treat cancer for several decades. However, ADR-induced renal injury is one of the most common side effects accompanying ADR therapy. In the present study, we revealed that astragaloside IV (ASIV) was beneficial for renal injury caused by Adriamycin. We demonstrated that ASIV significantly ameliorated kidney injury, improved renal dysfunction, reduced oxidative stress, alleviated iron accumulation, and inhibited the induction of ferroptosis by ADR. ASIV also rescued the intracellular levels of nuclear factor-erythroid-2-related factor 2 (Nrf2) and promoted nuclear translocation of Nrf2. These protective effects of ASIV on renal injury might be attained through the ASIV-induced activation of the Pi3K/Akt signaling pathway. In vitro, the treatment of the HK-2 cells with fer-1 or deferoxamine mesylate obviously improved cell viability during Adriamycin administration. On the other hand, the protective role of ASIV can be abrogated by RSL3 to some extent. Moreover, ASIV lowered the expression of transferrin receptor 1 and divalent metal transporter 1 while enhancing the expression of ferropotin 1 and glutathione peroxidase 4 in ADR administrated cells, the effects of which were akin to those of deferoxamine mesylate. Furthermore, ASIV increased the phosphorylation of Pi3K, Akt, and the expression of Nrf2 and glutathione peroxidase 4 compared to HK-2 cells stimulated by ADR. However, Pi3K inhibitor LY294002 abrogated these activations. In conclusion, ferroptosis may involve in ADR-induced nephrotoxicity, and ASIV might protect nephrocytes against ADR-induced ferroptosis, perhaps via activations of the Pi3K/Akt and Nrf2 signaling pathways.
