Effect of hesperidin on blood pressure and lipid profile: A systematic review and meta-analysis of randomized controlled trials

An updated and comprehensive review of the health benefits and pharmacological activities of hesperidin

OBJECTIVES

This review aims to comprehensively assess the health benefits and pharmacological activities of hesperidin, a flavonoid commonly found in citrus fruits. It consolidates recent research findings to provide insights into hesperidin's diverse health-promoting effects.

KEY FINDINGS

Hesperidin has gained significant attention recently for its notable pharmacological activities and potential health benefits. Studies reveal its antioxidant properties, protecting cells from oxidative damage, and its anti-inflammatory effects, inhibiting pro-inflammatory cytokines and enzymes. Also, hesperidin shows promise in cardiovascular health by reducing blood pressure and cholesterol levels and enhancing endothelial function. It also exhibits anticancer potential by hindering cell proliferation, inducing apoptosis, and suppressing tumour growth. Moreover, hesperidin demonstrates neuroprotective effects, potentially mitigating neuroinflammation and oxidative stress associated with neurodegenerative diseases. Furthermore, it displays beneficial effects in metabolic disorders such as diabetes, obesity, and fatty liver disease by influencing glucose metabolism, lipid profile, and insulin sensitivity.

SUMMARY

Hesperidin exhibits a wide range of health benefits and pharmacological activities, making it a promising candidate for therapeutic interventions in various diseases. Its antioxidant, anti-inflammatory, cardiovascular, anticancer, neuroprotective, and metabolic effects underscore its potential as a valuable natural compound for promoting health and preventing chronic diseases.

Radiosynthesis of [131I]I-Hesperidin: Optimization, physicochemical profiling, and computational insights for targeted radiopharmaceuticals

Hesperidin, a citrus flavonoid, has been investigated for its potential health benefits, including anticancer. However, the study of hesperidin as a theranostic agent and its cancer cellular uptake is still lacking. Therefore, in this research, we developed radiolabeling methods of hesperidin with Iodine-131 (131I) for radiotracing and investigating its potential theranostic application. Here, we showed that the radiochemical purity of [131I]I-hesperidin prepared with chloramine-T in methanol or DMSO, iodogen, and iodobeads as a catalyst were 97.75, 79.08, 78.13, and 49.91 %, respectively. The LogP and plasma protein-binding after 24 h of [131I]I-hesperidin prepared by chloramine-T in methanol were 0.54 ± 0.02 and 51.01 %, respectively. It was also stable in PBS for up to two days (RCP>90 %). The cellular uptake assay demonstrated the high and rapid uptake of [131I]I- hesperidin in A549 cells (92.03 % in 30 min), relatively low uptake in MCF-7 (21.30 % in 1 h), and deficient uptake in MDA-MB-231 (3.64 %). Interaction and binding energies of [131I]I-hesperidin-b toward EGFR, HER2, ERα, and ERβ, were -169.910; -131.574; -152.623, and -184.844 kJ/mol, respectively. Considering that the cellular uptake was the highest in A549 cells among the tested cells, the cellular uptake may be related to both EGFR and HER2 receptors. In addition, the interaction and binding energy of [131I]I-hesperidin-b toward AKT1 was -150.939 kJ/mol, indicating the potential [131I]I-hesperidin-b intervention in EGFR/HER2 signaling. Our data suggest that [131I]I-hesperidin-b is a potential radiopharmaceutical, especially for lung cancers with EGFR and HER2 expression. However, further studies are still needed to evaluate the uptake mechanism of [131I]I-hesperidin at the molecular level. Hopefully, [131I]I-hesperidin will provide an opportunity to investigate the biodistribution, pharmacokinetics, and its potential as a targeted therapeutic-diagnostic agent supported with beta decay for cancer cell eradication.

Human Supplementation with AM3, Spermidine, and Hesperidin Enhances Immune Function, Decreases Biological Age, and Improves Oxidative-Inflammatory State: A Randomized Controlled Trial

The positive effect of AM3, spermidine, and hesperidin, which have antioxidant and anti-inflammatory properties, on immunity is known, but their effect on the rate of aging, known as biological age (BA), is unclear. This work aims to test if the intake of a blend of AM3 (150 mg), spermidine (0.6 mg), and hesperidin (50 mg) for 2 months could decrease BA and improve immunity, redox, and inflammatory states. For this, 41 participants (30-63 years) were randomly divided into placebo and supplement groups. The supplement group took two capsules daily with AM3, spermidine, and hesperidin for two months, while the placebo group took capsules containing only calcium phosphate and talcum powder. Before and after the treatment, peripheral blood was collected. Immune function was assessed in leukocytes, redox state in whole-blood cells, erythrocytes, and plasma, and cytokine concentration in both mononuclear cell cultures and plasma. Finally, the Immunity Clock model was applied to determine BA. The results show that the intake of this blend improves the immune functions that constitute the Immunity Clock, decreasing BA by 11 years and reducing the oxidative-inflammatory state of the participants. Therefore, this supplement can be proposed as a strategy to rejuvenate BA and achieve healthy aging.
