Wang J, Xue X, Miao X. Antioxidant Effects of Quercetin Nanocrystals in Nanosuspension against Hydrogen Peroxide-Induced Oxidative Stress in a Zebrafish Model. Pharmaceuticals (Basel) 2023; 16:1209. [PMID: 37765017 PMCID: PMC10536595 DOI: 10.3390/ph16091209] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 08/13/2023] [Accepted: 08/23/2023] [Indexed: 09/29/2023] Open
Abstract
Quercetin, a flavonoid compound rich in hydroxyl groups, possesses antioxidant properties, whereas its poor water solubility limits its bioavailability. In pursuit of addressing the water solubility of quercetin and comprehending the impact of nanocrystal particle size on antioxidant efficacy, we prepared three different-sized quercetin nanocrystals, namely small (50 nm), medium (140 nm), and large (360 nm), using a nanosuspension method in this study. Within the in vitro setting, assessments employing solubility and radical scavenging assays revealed that quercetin nanocrystals displayed superior solubility (26, 21, and 13 fold corresponding to small, medium, and large particle sizes) and antioxidant performance compared to the coarse quercetin. Furthermore, quercetin nanocrystals of three particle sizes all demonstrated significant protection effects on the survival rate of H2O2-treated zebrafish at 72 h (77.78%, 73.33%, and 66.67% for small, medium, and large particle sizes, respectively), while the coarse quercetin group exhibited a low survival rate (53.3%) similar to the H2O2-treated group (47.8%). Moreover, all quercetin nanocrystals exhibited potent antioxidant capacity on both the antioxidants and enzymatic antioxidant system in H2O2-treated zebrafish to restore zebrafish to a normal state under oxidative stress. For instance, the levels of reactive oxygen species were reduced to 101.10%, 108.83%, and 109.77% of the normal levels for small, medium, and large particle-sized quercetin nanocrystals, respectively. In conclusion, quercetin nanocrystals demonstrated enhanced solubility, robust antioxidant capacity, and protective effects in zebrafish compared to coarse quercetin.

Abstract
Background Many neurodegenerative such as Alzheimer's disease (AD) are characterized by cholinergic dysfunction and oxidative stress which is a key event in neuronal death process. Thus, anticholinesterase and anti-oxidation compounds are two promising strategies in the development of AD drugs. Beyond their culinary use, spices are today studies for health purpose. In this study, some spices consumed in Cameroon were evaluated for their anticholinesterase and neuroprotective effects. Methods Colorimetric methods were used to determine total flavonoid and alkaloid content of a combinated extract (hydroethanolic + ethanolic extracts) of different selected spices. Aftermaths, anti-cholinesterase activity of spice extract was carried out using Ellman’s method. Finally, neuroprotective effects performed on human SK-N-SH cells stressed with H2O2 by assessing neuronal survival ( resazurin assay) and neuronal death (LDH assay). Results Flavonoid content of spices extract were ranged from 22.94 to 32.01 mg EQ/g DM and alkaloid content were ranged from 320 to 896 mg EQu/g DM. Among the spices studied, Xylopia parviflora presented the greatest acetylcholinesterase inhibition with an IC50 = 14 µg/mL. In Cell culture experiments, pre-incubation of SK-N-SH cell with the selected spices at different concentrations were improved neuronal survival and reduced the percentage of neuronal cells dead. Conclusion The present results reveal that selected spices consumed in Cameroon have good anticholinesterase activity as well as neuroprotective effect on SK-N-SH which may provide new natural compounds that could help in the management of Alzheimer's disease.

Abstract
Oxidative stress is the imbalance between reactive oxygen species (ROS) production, and accumulation and the ability of a biological system to clear these reactive products. This imbalance leads to cell and tissue damage causing several disorders in human body, such as neurodegeneration, metabolic problems, cardiovascular diseases, and cancer. Cucurbitaceae family consists of about 100 genera and 1,000 species of plants including mostly tropical, annual or perennial, monoecious, and dioecious herbs. The plants from Cucurbita species are rich sources of phytochemicals and act as a rich source of antioxidants. The most important phytochemicals present in the cucurbits are cucurbitacins, saponins, carotenoids, phytosterols, and polyphenols. These bioactive phyto-constituents are responsible for the pharmacological effects including antioxidant, antitumor, antidiabetic, hepatoprotective, antimicrobial, anti-obesity, diuretic, anti-ulcer activity, and antigenotoxic. A wide number of in vitro and in vivo studies have ascribed these health-promoting effects of Cucurbita genus. Results of clinical trials suggest that Cucurbita provides health benefits for diabetic patients, patients with benign prostate hyperplasia, infertile women, postmenopausal women, and stress urinary incontinence in women. The intend of the present review is to focus on the protective role of Cucurbita spp. phytochemicals on oxidative stress-related disorders on the basis of preclinical and human studies. The review will also give insights on the in vitro and in vivo antioxidant potential of the Cucurbitaceae family as a whole.

Abstract
CONTEXT Chard is used as an antidiabetic agent by the diabetic patients in Turkey. OBJECTIVE The effect of chard extract [Beta vulgaris L. var. cicla (Chenopodiaceae)] on the antioxidant system and the expression of surfactant-associated proteins (SP) in the lungs of hyperglycemic rats were examined. MATERIALS AND METHODS Hyperglycemia was induced by a single dose of streptozotocin (60 mg/kg) provided intraperitoneally. Fourteen days after the rats were rendered hyperglycemic, the chard (2 g/kg/d), insulin (6 U/kg/d), and chard plus insulin (as mentioned above) were administered to rats for 45 d. On day 60, rats' lungs were removed. Oxidative stress parameters and SP expression were assayed. RESULTS The lungs of hyperglycemic rats were characterized by the induced lipid and protein oxidation, elevated myeloperoxidase and xanthine oxidase activities, decreased glutathione levels, and reduced tissue factor and antioxidant enzymes activities (catalase, superoxide dismutase, glutathione peroxidase, and glutathione-S-transferase). Chard treatment alone and chard treatment combined with insulin were capable of achieving a regression of pulmonary oxidative stress, by inhibiting lipid and protein oxidation, and restoring the antioxidant system of hyperglycemic rats. SP-A expressions were significantly unchanged in all groups, whereas pro-SP-C and SP-D expressions were reduced in hyperglycemic rats. Pro-SP-C and SP-D levels were increased by chard and insulin administrations alone and combined in hyperglycemic rats. DISCUSSION AND CONCLUSION All treatments have a positive effect on the surfactant and antioxidant systems of the lungs of hyperglycemic rats. The best therapeutic effect was provided by treatment with chard extract alone in the compensation of hyperglycemic symptoms.

Abstract
Herbal and natural products have been used in folk medicine for centuries throughout the world. There has been renewed interest in screening higher plants for novel biologically active compounds, particularly those that effectively intervene in human ailments in the field of chronic diseases. The present study has been taken up to evaluate the free radical scavenging activity and tumor cell suppression potential of Premna serratifolia leaf in various in vitro model systems. The methanolic extract of P. serratifolia leaf was obtained by soxhlet extraction method. The superoxide radical scavenging activity, nitric oxide radical, hydroxyl radical, DPPH radical and ABTS radical scavenging activity and lipid peroxidation were determined. The tumor cell suppression cell potential was determined in three different cancer cell lines MCF7 (breast cancer), HepG2 (liver cancer) and A549 (lung cancer) by SRB assay. The study showed that the methanolic extract of P. serratifolia was having free radical scavenging activity against superoxide radical, nitric oxide radical, hydroxyl radical, DPPH radical, ABTS radical and inhibition of lipid peroxidation. The IC50 value showed the efficacy was dose dependent. The test extract showed cytotoxic activity against MCF7, HepG2 and A549 cells. The GI50, TGI and LC50 values were determined against each cell line and compared with standard drug Adriamycin. The present study proved the free radical scavenging activity and tumor cell suppression potential of P. serratifolia leaf in the selective in vitro model systems. The further study has to be carried out in the aspects of isolation of functional molecules of the extract.

Abstract
CONTEXT Vernonia cinerea (L.) Less [Compositae (Asteraceae)] is used traditionally for several medical purposes such as inflammation, pain, fever, and cancer. OBJECTIVES The present study identified the bioactive constituents in the methanol extract of Vernonia cinerea leaf and evaluated its antioxidant activity and acute toxicity. METHODS The identification of phytochemicals was accomplished by GC-MS and the major antioxidant phenolic compounds in the extract were quantified by HPTLC analysis. To quantify the essential elements, atomic absorption spectrophotometeric analysis was carried out. Total phenol and flavonoid content was measured by Folin-Ciocalteau reagent and 2% aluminium chloride, respectively. RESULTS GC-MS analysis identified the presence of 27 phytoconstituents. The predominant phenolic compound in the extract as quantified by HPTLC was gallic acid (1.92 mg/g) followed by rutin (0.705 mg/g), quercetin (0.173 mg/g), caffeic acid (0.082 mg/g) and ferulic acid (0.033 mg/g). The following elements were quantified: Fe (0.050 ppm), Mn (0.022 ppm), Co (0.0180 ppm), Pb (0.029 ppm), Hg (3.885 ppm) and Se (4.5240 ppm). The antioxidant activity of the extract increased with increasing concentration and the correlation (r²) for all in vitro assays were satisfactory. CONCLUSIONS V. cinerea extract has significant (p < 0.05) antiradical activity. Hence, V. cinerea may have potential medicinal value and can be used in the formulation of pharmacological products for degenerative diseases.

Abstract
Objectives: The objective of this study was to evaluate the antistress activity of Momordica charantia (MC) fruit extract on stress-induced changes in albino rats and also to explore attenuating effects of MC on in vitro lipid peroxidation in rat brain. Materials and Methods: In this study, Wistar albino rats (180–200 g) were used. Plasma corticosterone and monoamines—5-hydroxy tryptamine (5-HT), norepinephrine (NE), epinephrine (E) and dopamine (DA) in cortex, hypothalamus and hippocampus regions of brain were determined in animals under different stressful conditions. Ethanolic fruit extract of MC, at doses of 200 and 400 mg/kg, was used. The oxidative stress paradigms used in in vivo models were acute stress (AS) and chronic unpredictable stress (CUS). Panax quinquefolium (PQ) was used as a standard in in vivo models and ascorbic acid was used as a reference standard in the in vitro method. Results: Subjecting the animals to AS (immobilization for 150 min once only) resulted in significant elevation of plasma corticosterone levels and brain monoamine levels. Pretreatment with MC at doses of 200 and 400 mg/kg p.o. significantly countered AS-induced changes and a similar effect was exhibited by PQ at 100 mg/kg p.o. In the CUS regimen (different stressors for 7 days), plasma corticosterone levels were significantly elevated whereas the levels of 5-HT, NE, E, and DA were depleted significantly. Pretreatment with MC (200 and 400 mg/kg) attenuated the CUS-induced changes in the levels of above monoamines in cortex, hypothalamus, and hippocampus regions of brain and plasma corticosterone in a dose-dependent manner. Furthermore, MC extract (1000–5000 μg/mL) exhibited a significant quenching effect on in vitro lipid peroxidation indicating its strong antioxidant activity which was compared with ascorbic acid. Conclusions: This study reveals the antistress activity of MC as it significantly reverted the stress-induced changes, and the activity might be attributed to its antioxidant activity since stress is known to involve several oxidative mechanisms.

Abstract
The present study describes the antioxidant activities of ethanol extract from Gymnema montanum (GLEt) which is an endemic plant of India. Antioxidant activity of the GLEt was studied in vitro based on scavenging of hydroxyl radicals, superoxide anions, nitric oxide, hydrogen peroxide, peroxynitrite, reducing power and inhibition of lipid peroxidation estimated in terms of thiobarbituric acid reactive substances (TBARS). Further, we examined its protective effect against alloxan-induced oxidative stress in pancreatic beta-cells, HIT-T15 by measuring the free radical generation, malonaldehyde formation and antioxidant levels such as CAT, GPx and GSH. Results showed that G. montanum leaves exhibited significant antioxidant activities measured by various in vitro model systems. The HIT-T15 cell line studies showed the tendency of GLEt to increase antioxidant levels meanwhile decrease the free radical formation and inhibit the lipid peroxidation. The antioxidant activity was found to be well correlated with the phenolic phytochemicals present in the extract. GC-MS analyses revealed the presence of few phenolic compounds in the extract. As this plant has already been demonstrated for a variety of medicinal properties from our laboratory, results of this study suggest that G. montanum is an interesting source for antioxidant compounds and useful for various therapeutic applications.

Abstract
Reactive oxygen species are implicated in various inflammatory disorders. Vitex negundo is mentioned in Ayurveda as useful in treating arthritic disorders. The present work was undertaken to evaluate the antioxidant potential and anti-inflammatory activity of the plant. The total methanol extract of the plant was standardized in terms of total polyphenols. The standardized extract in a dose of 100 mg/kg caused a comparable reduction in edema with that of diclofenac sodium (25 mg/kg) when evaluated for antiinflammatory activity by carrageenan-induced rat paw edema method. The extract also exhibited a strong free radical scavenging activity by 1,1-diphenyl-2-picrylhydrazyl method and caused a significant reduction in the formation of thiobarbituric acid reacting substances when evaluated for its lipid peroxidation inhibitory activity. The results strongly suggest that radical quenching may be one of the mechanisms responsible for its antiinflammatory activity.
