Objective: To evaluate the effect of salidroside on oxygen and glucose deprivation (OGD)-treated NT2 cells and its underlying mechanisms of action. Methods: Retinoic acid was used to induce the differentiation of NT2 cells into neurons. The effects of salidroside on survival, apoptosis, inflammatory response, and oxidative stress of neurons undergoing OGD were evaluated. Using precursor cells as controls, the effect of salidroside on the differentiation progression of OGD-treated cells was evaluated. In addition, the effect of erastin, a ferroptosis inducer, on NT2 cells was examined to investigate the underlying mechanisms of neuroprotective action of salidroside. Results: Salidroside alleviated the effects of OGD on neuronal survival, apoptosis, inflammation, and oxidative stress, and promoted NT2 cell differentiation. Moreover, salidroside prevented ferroptosis of OGD-treated cells, which was abolished following erastin treatment, indicating that ferroptosis mediated the regulatory pathway of salidroside. Conclusions: Salidroside attenuates OGD-induced neuronal injury by inhibiting ferroptosis and promotes neuronal differentiation.

Objective: To investigate the relationship between triterpenoid saponin content and antioxidant, antimicrobial, and α-glucosidase inhibitory activities of 70% ethanolic, butanolic, aqueous, supernate and precipitate extracts of Juglans regia leaves. Methods: Triterpenoid saponins of different Juglans regia leaf extracts were measured by the vanillin method. Antioxidant activity was evaluated against DPPH and ABTS free radicals. We also assessed α-glucosidase inhibitory and antimicrobial activities of the leaf extracts. Pearson′s correlation coefficient was evaluated to determine the correlation between the saponin content and biological activities. Results: The butanolic extract was most effective against DPPH with an IC50 of 6.63 μg/mL, while the aqueous extract showed the highest scavenging activity against ABTS free radical with an IC50 of 42.27 μg/mL. Pearson′s correlation analysis indicated a strong negative correlation (r = -0.956) between DPPH radical scavenging activity (IC50) and the saponin content in the samples examined. In addition, the aqueous extract showed the best α-glucosidase inhibitory activity compared with other extracts. All the extracts had fair antibacterial activity against Bacillus subtilis, Escherichia coli, and Klebsiella pneumoniae except for the aqueous extract. Conclusions: Juglans regia extracts show potent antioxidant, antimicrobial, and α-glucosidase inhibitory activities. There is a correlation between saponin levels in Juglans regia leaf extracts and the studied activities. However, additional research is required to establish these relationships by identifying the specific saponin molecules responsible for these activities and elucidating their mechanisms of action.

Kaempferol, a natural plant-origin flavonoid, exhibits therapeutic anti-inflammatory, antioxidant, anticancer, antidiabetic, and neuroprotective properties. Kaempferol acts within several distinct mechanisms like apoptotic induction in cancer cells, enzymatic inhibition, signalling pathway inhibition, and downregulation in cell viability during the G2/M phase of cell division. This review summarizes the therapeutic effects of kaempferol against several health ailments. The recent progress on kaempferol obtained from fruits and vegetables as an antioxidant, anti-inflammatory, anticancer, antidiabetic, and neuroprotective agent and its mechanisms of action are also discussed. In addition, kaempferol has been reported to be present in wastes and byproducts from post-fruit and vegetable processing. Thus, a paradigm shift towards valorizing fruits and vegetable industrial wastes/byproducts to obtain bioactive kaempferol can support the circular economy pillar for generating wealth from waste and for finding a sustainable alternative source.

Objective: To explore the anti-melanogenic potential of Cyrtomium falcatum. Methods: The effects of Cyrtomium falcatum crude extract and its solvent fractions on tyrosinase activity, melanin content, and the expressions of melanogenesis-related genes and proteins were analyzed in α-melanocyte-stimulating hormone (α-MSH)-stimulated B16F10 cells. Results: α-MSH treatment significantly increased tyrosinase activity, and extracellular and intracellular melanin content, as well as the expression levels of tyrosinase, microphthalmia-associated transcription factor (MITF), tyrosinase-related protein (TRP)-1, and TRP-2 in B16F10 cells. Treatment with Cyrtomium falcatum crude extract and its solvent fractions reduced tyrosinase activity and extracellular and intracellular melanin content and downregulated the expression levels of tyrosinase, MITF, TRP-1, and TRP-2 in a dose-dependent manner. Conclusions: Cyrtomium falcatum has potential anti-melanogenesis effects and can be used as a potential source material in cosmeceutical industry for the research and development of novel lead molecules with whitening properties.

Arsenic toxicity, imposed mainly by arsenic-contaminated groundwater, is considered a critical threat to global communal health, as there is no specific and proven conventional therapy for chronic arsenic toxicity, i.e., arsenicosis, which is an insidious global public health menace affecting 50 countries. Alternative options should, therefore, be explored for the mitigation of arsenicosis. Literature survey reveals several natural compounds from plants possess significant protective efficacy against arsenic toxicity in chiefly preclinical and few clinical investigations. The studies on the ameliorative effects of plant-derived natural compounds against arsenic toxicity published in the last 25 years are collated. Forty-eight plant-based natural compounds possess alleviative effects on experimental arsenic-induced toxicity in animals, six of which have been reported to be clinically effective in humans. A potential nutraceutical or therapeutic candidate against arsenicosis for humans may thus be developed with the help of recent advancements in research in this area, along with the currently available treatments.

Objective: To investigate the cardioprotective effect of beta-glucan against isoproterenol-induced cardiotoxicity in rats, and elucidate the underlying mechanism. Methods: Rats were orally pretreated with beta-glucan (40 mg/kg body weight) for 30 d, and isoproterenol (20 mg/100 g body weight) was administered on days 31 and 32. The effects of beta-glucan on markers of cardiac injury, hemodynamic changes, production of proinflammatory cytokines, and the corresponding mRNA expressions were evaluated. In addition, histological analysis was performed. Results: Pretreatment with beta-glucan prevented isoproterenol-induced cardiac injury by preserving the structural and functional integrity of the plasma membrane and attenuating the production of proinflammatory cytokines (NF-κB, TNF-α, IL-6, IL-Ιβ, and IFN-γ) in the heart. Moreover, beta-glucan significantly downregulated the mRNA expression of ACE, AT1R, TNF-α, IL-6, NF-κB, caspase-3, TLR-4, and Bax, and upregulated Bcl-2 in the heart. At the same time, pretreatment with beta-glucan alleviated myocardial damage as reflected in a reduction in myonecrosis, edema, and erythrocyte extravasation with almost imperceptible inflammation. Conclusions: Beta-glucan can protect against isoproterenol-induced cardiotoxicity by attenuating cardiac inflammation and apoptosis and regulating the ACE-AT1R axis, thereby preventing cardiac remodeling.

Objective: To assess the effect of sericin against pentylenetetrazole (PTZ) kindling epilepsy and its associated comorbidities. Methods: Epilepsy was induced with PTZ at the dose of 30 mg/kg i.p. on alternative days for 25 days in rats. Sericin was administered orally at the doses of 250, 500, and 1000 mg/kg for 35 days. The behavioral activities were performed using an elevated plus maze, forced swim test, and Morris water maze test. A PTZ challenge test was conducted on day 32. On day 35, rats were sacrificed to perform oxidative stress, mitochondrial dysfunction, neuroinflammation, neurotransmitters, GABA-T activity, and histopathological analyses. Results: Sericin at 500 and 1000 mg/kg significantly reduced behavioral changes and neuroinflammatory cytokines, as well as improved oxidative stress, mitochondrial enzyme complex activity, neurotransmitter level, and GABA-T enzymatic activity (P<0.05). Moreover, sericin improved the neuronal survival altered by PTZ kindling in rat hippocampus. Conclusions: Sericin mitigates epilepsy-associated secondary complications possibly by the modulation of mitochondrial enzyme complexes and GABA-T enzymatic activity.
