Abstract
BACKGROUND The P2X7 receptor (P2X7R) is known to play a significant role in regulating various pathological processes associated with immune regulation, neuroprotection, and inflammatory responses. It has emerged as a potential target for the treatment of diseases. In addition to chemically synthesized small molecule compounds, natural products have gained attention as an important source for discovering compounds that act on the P2X7R. PURPOSE To explore the research progress made in the field of natural product-derived compounds that act on the P2X7R. METHODS The methods employed in this review involved conducting a thorough search of databases, include PubMed, Web of Science and WIKTROP, to identify studies on natural product-derived compounds that interact with P2X7R. The selected studies were then analyzed to categorize the compounds based on their action on the receptor and to evaluate their therapeutic applications, chemical properties, and pharmacological actions. RESULTS The natural product-derived compounds acting on P2X7R can be classified into three categories: P2X7R antagonists, compounds inhibiting P2X7R expression, and compounds regulating the signaling pathway associated with P2X7R. Moreover, highlight the therapeutic applications, chemical properties and pharmacological actions of these compounds, and indicate areas that require further in-depth study. Finally, discuss the challenges of the natural products-derived compounds exploration, although utilizing compounds from natural products for new drug research offers unique advantages, problems related to solubility, content, and extraction processes still exist. CONCLUSION The detailed information in this review will facilitate further development of P2X7R antagonists and potential therapeutic strategies for P2X7R-associated disorders.

Abstract
The application of microwave-assisted drying is a promising technique due to the features of process sustainability that are usable for responsible productions. It is largely applied for the stabilization of food products, especially in the agro-food sector. In this study, the weed Portulaca oleracea L. (purslane), with its richness in antioxidant components in addition to its recognized pharmacological properties, has been considered due to its potential to be a natural, well-accepted future food. Attention was focused on the role of the heat and mass transfer rates involved in the drying processes on the nutritional profile of the dried products. For this purpose, different drying protocols (convective, microwave irradiation, microwave-vacuum irradiation) were applied to different parts of purslane herb (apical, twigs, entire structures) and chemical characterizations were performed by a GC/MS analysis of the extracts of the dried products. The results show that microwave treatments can assure a better preservation of fatty acids such as SFAs, MUFAs, and PUFAs (which constitute over 90% of the total components in the apical part, 65% in twigs, and 85% in microwave-vacuum-dried entire purslane samples) and phytosterols (their highest preservation was found in microwave-dried twigs) compared with convective treatments. The chemical composition variability as well as treatment times depend on the drying rates (in microwave treatments, the times are on a minute scale and the rates are up to three orders of magnitude greater than convective ones), which in turn depend on the heating transport phenomena. This variability can lead towards products that are diversified by properties that transform a weed into a valorized food source.

Abstract
Soil is an essential resource, and its degradation is challenging modern agriculture, while its impact is expected to increase in the near future. One of the strategies to address this issue is to incorporate new alternative crops able to tolerate arduous conditions, as well as for the use of sustainable agricultural practices in order to recover and/or improve soil health. Additionally, the increasing market for new functional/healthy natural foods promotes the search for potential alternative crop species with promising bioactive compounds content. For this purpose, wild edible plants are a key option because they have already been consumed for hundreds of years in traditional gastronomy and there is well-established evidence of their health-promoting effects. Moreover, since they are not a cultivated species, they are able to grow under natural conditions without human intervention. Among them, common purslane is an interesting wild edible species and a good candidate for integration in commercial farming systems. With worldwide spread, it is able to tolerate drought, salinity and heat stress and is already used in traditional dishes, while it is highly appreciated for its high nutritional value due to its bioactive compound content, especially omega-3 fatty acids. In this review, we aim to present the breeding and cultivation practices of purslane, as well as the effects of abiotic stressors on yield and chemical composition of the edible parts. Finally, we present information that helps to optimize purslane cultivation and facilitate its management in degraded soils for their exploitation in the existing farming systems.

Abstract
One potential avenue to increase the production of valuable protein ingredients for the food industry is developing vegetable proteins from non-traditional plant sources. In the present study, the composition, structure and techno-functional characteristics of defatted purslane flour (DF), protein concentrate (PC), and protein isolate (AP) were investigated. The results revealed that DF, PC, and PI contained low levels of moisture, ash, and fat. However, there were significant differences (P < 0.05) in protein content between DF, PC, and PI (32.9, 60.8 and 90.9%, respectively). The techno-functional characteristics of purslane proteins were enhanced by processing purslane flour into PC and PI products. Furthermore, the ratios of total essential amino acids to total amino acids in purslane protein samples were well above that stated for ideal food proteins. SDS-PAGE analysis indicated three subunits of protein in DF, PC, and PI. Scanning electron microscopy revealed that DF exhibited a compact-like structure; PC had a small, flaky, but porous type of particle, and PI had an intact flake-like structure. The FTIR analysis revealed that some alterations in the secondary structure of protein were occurred. In summary, purslane proteins can be considered new functional food ingredients with different nutritional and technological characteristics.

Abstract
This work searched for the phyto-therapeutic potential and nutritional value of seeds from the halophyte Cladium mariscus L. (Pohl.), aiming at its use as a source of bioactive ingredients for the food industry. Hence, the nutritional profile, including minerals, of seeds biomass was determined; food-grade samples were prepared, and their phytochemical fingerprinting assessed. Extracts were evaluated for in vitro antioxidant potential, inhibitory capacity towards enzymes related to neuroprotection, diabetes, and hyperpigmentation, and anti-inflammatory properties, along with a toxicological assessment. Sawgrass seeds can be considered a proper nutritional source with a good supply of minerals. All extracts had a high level of total phenolics (65.3−394.4 mg GAE/g DW) and showed a chemically rich and diverse profile of metabolites that have several biological properties described (e.g., antioxidant, anti-inflammatory). Extracts had no significant toxicity (cell viabilities > 80%) and were overall strong antioxidants (particularly at radical scavenging and reducing iron), effective tyrosinase inhibitors (55−71 mg KAE/g DW), showed anti-inflammatory properties (30−60% NO decrease), and had moderate capacity to inhibit enzymes related to neuroprotection (AChE 3.7−4.2, BChE 4.3−6.0 mg GALE/g DW) and diabetes (α-glucosidase 1.0−1.1, α-amylase 0.8−1.1 mmol ACAE/g). Altogether, results suggest that sawgrass seeds have the potential to be exploited as a new food product and are a reservoir of bioactive molecules with prospective applications as ingredients for value-added, functional, and/or preservative food products.

Abstract
This study aimed to determine the association between the seed coat color of two chia seed genotypes for their composition, protein content, amino acid, and fatty acid profiles. The optimal pH for protein isolation for both genotypes (BCPI and WCPI) was 10, based on protein purity and solubility. Fatty acid profiling indicated, overall, 18 different fatty acids higher in BCPI10 with linolenic acid domination (∼66%) followed by linoleic acid (∼19%) and oleic acid (∼6%), contributing PUFAs (∼86%). Optimized protein isolates, black (BCPI10) and white (WCPI10) chia, had shown purity, L*-value, solubility, and yields of 90.65%, 75.86%, 77.75%, 11.30%, and 90.00%, 77.83%, 76.07%, 10.69%, respectively. BCPI10 depicted higher EAA (33.19 g/100 g N) and EEA indices (57.676%) compared to WCPI10 (32.14 g/100 g N) and 56.360%, respectively. Amino acid profiling indicated higher, PER, TAA, TEAA, TNEAA, TAAA, TBA, acidic AA values for BCPI10, and higher leucine/isoleucine ratio for WCPI10 having leucine and sulfur amino acids as limiting amino acids. BCPI10 had higher sulfur-containing amino acid contents, as the main contributor to the albumin a water-soluble fraction, leading to its higher in vitro digestibility (71.97%) than WCPI10 (67.70%). Both isolates exhibited good WHC and OHC of 3.18, 2.39 and 3.00, 2.20, respectively. Both protein isolates had similar ∆Td (°C) values with some variation in FTIR spectrum from 1000 cm-1 to 1651 cm-1 having more peak intensity for BCPI10. SDS-PAGE indicated bands at 150 kDa, representing globulin and mild bands at 25-33 kDa for glutelin and albumin. A significant (p < 0.05) variation reported in this study for protein and lipid profiles of both genotype attributes to genetic differences between the seeds. PRACTICAL APPLICATION: Based on the nutritional profile, both chia seed isolates (black and white) are suitable for consumption with an edge for black seed when supplemented with their limiting amino acids. The high values of the functional properties and structural characteristics combined with high nutritional values make the chia protein isolate an excellent source of raw material for various food formulations. Fatty acid profile of the oils from the genotypes showed the presence of high amounts of unsaturated fatty acids, especially the PUFAs with more number of fatty acids in black chia seed. The excellent lipid profile of chia seed oil indicates the benefit of using chia seed oil as a source of essential fatty acids in the human diet for optimal health.

Abstract
The omega−3 (n−3) polyunsaturated fatty acids (PUFAs) eicosapentaenoic acid (EPA) and docosahexaenoic (DHA) acid are well known to protect against numerous metabolic disorders. In view of the alarming increase in the incidence of chronic diseases, consumer interest and demand are rapidly increasing for natural dietary sources of n−3 PUFAs. Among the plant sources, seed oils from chia (Salvia hispanica), flax (Linum usitatissimum), and garden cress (Lepidium sativum) are now widely considered to increase α-linolenic acid (ALA) in the diet. Moreover, seed oil of Echium plantagineum, Buglossoides arvensis, and Ribes sp. are widely explored as a source of stearidonic acid (SDA), a more effective source than is ALA for increasing the EPA and DHA status in the body. Further, the oil from microalgae and thraustochytrids can also directly supply EPA and DHA. Thus, these microbial sources are currently used for the commercial production of vegan EPA and DHA. Considering the nutritional and commercial importance of n−3 PUFAs, this review critically discusses the nutritional aspects of commercially exploited sources of n−3 PUFAs from plants, microalgae, macroalgae, and thraustochytrids. Moreover, we discuss issues related to oxidative stability and bioavailability of n−3 PUFAs and future prospects in these areas.

Abstract
In the present study, the antimicrobial and cytotoxic activities, as well as the fatty acids composition in vegetable seed oils from linseed, purslane, luffa, and pumpkin were evaluated. For this purpose, two linseed oils and one luffa oil were commercially obtained, while purslane and pumpkin oils were obtained from own cultivated seeds. The results showed a variable fatty acids composition among the tested oils, with α-linolenic, linoleic, oleic, palmitic, and stearic acid being the most abundant compounds. In regards to particular oils, linseed oils were a rich source of α-linolenic acid, luffa and pumpkin oil were abundant in linoleic acid, while purslane oil presented a balanced composition with an almost similar amount of both fatty acids. Luffa oil was the most effective against two of the tested cancer cell lines, namely HeLa (cervical carcinoma) and NCI-H460 (non-small cell lung cancer), while it also showed moderate toxicity against non-tumor cells (PLP2 cell line). Regarding the antibacterial activity, linseed oil 3 and pumpkin oil showed the highest activity against most of the tested bacteria (especially against Enterobacter cloacae and Escherichia coli) with MIC and MBC values similar to the used positive controls (E211 and E224). All the tested oils showed significant antifungal activities, especially luffa and pumpkin oil, and for most of the tested fungi they were more effective than the positive controls, as for example in the case of Aspergillus versicolor, A. niger, and Penicillium verrucosum var. cyclopium. In conclusion, the results of our study showed promising antimicrobial and cytotoxic properties for the studied seed oils which could be partly attributed to their fatty acids composition, especially the long-chain ones with 12–18 carbons.

Abstract
AIM Acrylamide (ACR) is an environmental pollutant with well-demonstrated neurotoxic and neurodegenerative effects in both humans and experimental animals. The present study aimed to investigate the neuroprotective effect of Portulaca oleracea seeds extract (PSE) against ACR-induced neurotoxicity in rats and its possible underlying mechanisms. PSE was subjected to phytochemical investigation using ultra-high-performance liquid chromatography (UPLC) coupled with quantitative time of flight mass spectrometry (qTOF-MS). Multivariate, clustering and correlation data analyses were performed to assess the overall effects of PSE on ACR-challenged rats. Rats were divided into six groups including negative control, ACR-intoxicated group (10 mg/kg/day), PSE treated groups (200 and 400 mg/kg/day), and ACR + PSE treated groups (200 and 400 mg/kg/day, respectively). All treatments were given intragastrically for 60 days. PSE markedly ameliorated brain damage as evidenced by the decreased lactate dehydrogenase (LDL), increased acetylcholinesterase (AchE) activities, as well as the increased brain-derived neurotrophic factor (BDNF) that were altered by the toxic dose of ACR. In addition, PSE markedly attenuated ACR-induced histopathological alterations in the cerebrum, cerebellum, hippocampus and sciatic nerve and downregulated the ACR-inclined GFAP expression. PSE restored the oxidative status in the brain as indicated by glutathione (GSH), lipid peroxidation and increased total antioxidant capacity (TAC). PSE upregulated the mRNA expression of protein kinase B (AKT), which resulted in an upsurge in its downstream cAMP response element-binding protein (CREB)/BDNF mRNA expression in the brain tissue of ACR-intoxicated rats. All exerted PSE beneficial effects were dose-dependent, with the ACR-challenged group received PSE 400 mg/kg dose showed a close clustering to the negative control in both unsupervised principal component analysis (PCA) and supervised orthogonal partial least square discriminant analysis (OPLS-Da) alongside with the hierarchical clustering analysis (HCA). The current investigation confirmed the neuroprotective capacity of PSE against ACR-induced brain injury, and our findings indicate that AKT/CREB pathways and BDNF synthesis may play an important role in the PSE-mediated protective effects against ACR-triggered neurotoxicity.

Abstract
The Mayten tree (Maytenus boaria Mol.), a native plant of Chile that grows under environmentally limiting conditions, was historically harvested to extract an edible oil, and may represent an opportunity to expand current vegetable oil production. Seeds were collected from Mayten trees in north-central Chile, and seed oil was extracted by solvent extraction. The seed oil showed a reddish coloration, with quality parameters similar to those of other vegetable oils. The fatty acid composition revealed high levels of monounsaturated and polyunsaturated fatty acids. Oleic and linoleic acids, which are relevant to the human diet, were well represented in the extracted Mayten tree seed oil. The oil displayed an antioxidant capacity due to the high contents of antioxidant compounds (polyphenols and carotenoids) and may have potential health benefits for diseases associated with oxidative stress.
