Abstract
The polyphenolic profile of the hydroethanol extract of Asphodelus fistulosis L. roots (HEAFR) was determined using LC-HRMS/MS technique while its antioxidant activity was evaluated using five different methods (DPPH, reducing power, reduction via Fe+2 phenanthroline complex formation, ABTS•+, silver ion reduction capacity). In addition, preliminary toxicity and cytotoxicity of the HEAFR were assessed on larvae. The results revealed the presence of 40 polyphenols, with luteolin (23.89%), luteolin-7-O-β-D-glucoside (15.32%), emodin (13.49%) and feruloyltyramine (10.57%) as major compounds. The highest antioxidant activity was shown in the ABTS•+ assay (IC50: 89.34 ± 5.65 μg/mL) whereas preliminary toxicity and cytotoxicity tests showed that this extract is non-toxic. Moreover, the HEAFR exhibited a good protective effect of erythrocyte membranes at a high concentration of 800 μg/mL and showed comparable stabilisation efficiency to gallic acid at a concentration of 200 μg/mL. These findings highlight the HEAFR potential as a non-toxic antioxidant agent with protective effects on cell membranes.

Abstract
A new glucosyl flavone, 5,7,2',5'-tetrahydroxyflavone 7-O-β-d-glucopyranoside, named loeflingiin, together with apigenin 6-C-glucoside (isovitexin), coumarins citropten and isompinellin, triterpenoids betulin and betulinic acid, and a mixture of phytosterols β-sitosterol, stigmasterol and campesterol were isolated for the first time from the leaves of wild Plantago loeflingii L. (Plantaginaceae) collected in the Iraqi Kurdistan region. The plant is used by local people to treat wounds and as a vulnerary remedy. The structures of isolated compounds were determined by spectroscopic analysis. The activities of isovitexin and loeflingiinon the viability of breast (MCF7), ovarian (BG-1), endometrial (Ishikawa), and mesothelioma (IST-MES1) human cancer cells and two normal cell lines were determined with an MTT assay. Notably, the new 7-O-glucosyl flavone showed effects higher than cisplatin against the Ishikawa and IST-MESI cell lines. The significant biological activities exhibited by all the compounds isolated from P. loeflingii provided scientific evidence to support the use of the plant in the Kurdish traditional medicine.

Antioxidants (Basel) 2023; 12:2092. [PMID: 38136212 PMCID: PMC10740450 DOI: 10.3390/antiox12122092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 11/26/2023] [Accepted: 12/01/2023] [Indexed: 12/24/2023] Open
Abstract
Previous studies detail that different blood groups are associated with incidence of oxidative stress-related diseases such as certain carcinomas. Bioactive compounds represent an alternative for preventing this oxidative stress. The aim of this study was to elucidate the impact of blood groups on the erythroprotective potential of fucoxanthin, β-Carotene, gallic acid, quercetin and ascorbic acid as therapeutic agents against oxidative stress. The impact of ABO blood groups on the erythroprotective potential was evaluated via the antioxidant capacity, blood biocompatibility, blood susceptibility and erythroprotective potential (membrane stabilization, in vitro photostability and antihemolytic activity). All tested antioxidants exhibited a high antioxidant capacity and presented the ability to inhibit ROO•-induced oxidative stress without compromising the cell membrane, providing erythroprotective effects dependent on the blood group, effects that increased in the presence of antigen A. These results are very important, since it has been documented that antigen A is associated with breast and skin cancer. These results revealed a probable relationship between different erythrocyte antigens with erythroprotective potential, highlighting the importance of bio-targeted drugs for groups most susceptible to certain chronic-degenerative pathologies. These compounds could be applied as additive, nutraceutical or encapsulated to improve their bioaccessibility.

Natural sources, biological effects, and pharmacological properties of cynaroside. Biomed Pharmacother 2023; 161:114337. [PMID: 36812715 DOI: 10.1016/j.biopha.2023.114337] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Revised: 01/19/2023] [Accepted: 01/27/2023] [Indexed: 02/22/2023] Open
Abstract
Cynaroside is a flavonoid, isolated from several species belonging to the Apiaceae, Poaceae, Lamiaceae, Solanaceae, Zingiberaceae, Compositae and other families and it can be extracted from seeds, roots, stems, leaves, barks, flowers, fruits, aerial parts, and the whole plant of these species. This paper discloses the current state of knowledge on the biological/pharmacological effects and mode of action to better understand the numerous health benefits of cynaroside. Several research works revealed that cynaroside could have beneficial effects on various human pathologies. Indeed, this flavonoid exerts antibacterial, antifungal, antileishmanial, antioxidant, hepatoprotective, antidiabetic, anti-inflammatory, and anticancer effects. Additionally, cynaroside exhibits its anticancer effects by blocking MET/AKT/mTOR axis by decreasing the phosphorylation level of AKT, mTOR, and P70S6K. For antibacterial activity, cynaroside reduces biofilm development of Pseudomonas aeruginosa and Staphylococcus aureus. Moreover, the incidence of mutations leading to ciprofloxacin resistance in Salmonella typhimurium was reduced after the treatment with cynaroside. In addition, cynaroside inhibited the production of reactive oxygen species (ROS), which reduced the damage to mitochondrial membrane potential caused by hydrogen peroxide (H2O2). It also enhanced the expression of the anti-apoptotic protein Bcl-2 and lowered that of the pro-apoptotic protein Bax. Cynaroside abrogated the up-regulation of c-Jun N-terminal kinase (JNK) and p53 protein expression triggered by H2O2. All these findings suggest that cynaroside could be used to prevent certain human diseases.

Abstract
In the present study, preliminary phytochemical investigations were performed on the fruit essential oil and antioxidant-rich methanolic extracts of the fruits and roots of Ferula drudeana, the putative Anatolian ecotype of the Silphion plant, to corroborate its medicinal plant potential and identify its unique characteristics amongst other Ferula species. The essential oil from the fruits of the endemic species Ferula drudeana collected from Aksaray was analyzed by GC and GC/MS. The main components of the oil were determined as shyobunone (44.2%) and 6-epishyobunone (12.6%). The essential oil of the fruits and various solvent extracts of the fruits and roots of F. drudeana were evaluated for their antibacterial and anticandidal activity using microbroth dilution methods. The essential oil of the fruits, methanol, and methylene chloride extracts of the fruits and roots showed weak to moderate inhibitory activity against all tested microorganisms with MIC values of 78-2000 µg/mL. However, the petroleum ether extract of the roots showed remarkable inhibitory activity against Candida krusei and Candida utilis with MIC values of 19.5 and 9.75 µg/mL, respectively. Furthermore, all the samples were tested for their antioxidant activities using DPPH• TLC spot testing, online HPLC-ABTS screening, and DPPH/ABTS radical scavenging activity assessment assays. Methanolic extracts of the fruits and roots showed strong antioxidant activity in both systems.

Abstract
The horticultural production of bell peppers generates large quantities of residual biomass. Abiotic stress stimulates the production of protective flavonoids, so the deliberate application of stress to the plants after fruit harvest could provide a strategy to valorize horticultural residuals by increasing flavonoid concentrations, facilitating their industrial extraction. Here we exposed two Capsicum cultivars, a chilli and a bell pepper, to cold and salt stress and combinations thereof to determine their valorization potential. Noninvasive image-based phenotyping and multiparametric fluorescence measurements indicated that all stress treatments inhibited plant growth and reduced the leaf chlorophyll fluorescence index, with the chilli cultivar showing greater sensitivity. The fluorescence-based FLAV index allowed the noninvasive assessment of foliar luteolin glycosides. High-performance liquid chromatography-mass spectrometry (HPLC-MS) analysis showed that moderate cold increased the levels of two foliar antioxidant luteolin glycosides in both cultivars, with bell pepper containing the highest amounts (induced to maximum 5.5 mg g-1 DW cynaroside and 37.0 mg g-1 DW graveobioside A) after combined stress treatment. These data confirm the potential of abiotic stress for the valorization of residual leaf biomass to enhance the industrial extraction of antioxidant and bioactive flavonoids.

Abstract
This study aimed to determine the composition and content of polyphenols in the dry extract obtained from the hydrodistilled residue by-product of the wild bergamot (Monarda fistulosa L., Lamiaceae Martinov family) herb (MFDE) and to evaluate its safety and pharmacological properties. The total phenolic content (TPC) in the MFDE was 120.64 mg GAE/g. The high-performance liquid chromatography (HPLC) analysis showed the presence of a plethora of phenolic compounds, including hydroxycinnamic acids and flavone derivatives in the MFDE, with rosmarinic acid and luteolin-7-O-glucoside being the main components. With an IC50 value of 0.285 mg/mL, it was found to be a strong DPPH radical scavenger. The acute toxicity study results indicate that the oral administration of MFDE to rats at the doses of 500–5,000 mg/kg did not produce any side effects or death in animals which indicates its safety. The results of the in vivo assay showed that the MFDE dose-dependently inhibited paw oedema and significantly reduced the number of writings in mice induced by the acetic acid injection suggesting its potent anti-inflammatory and analgesic activities, respectively. The conducted studies revealed that M. fistulosa hydrodistilled residue by-product could be regarded as a new natural source of polyphenols with valuable pharmacological properties.

Extract of Herba Anthrisci cerefolii: Chemical Profiling and Insights into Its Anti-Glioblastoma and Antimicrobial Mechanism of Actions. Pharmaceuticals (Basel) 2021; 14:ph14010055. [PMID: 33445425 PMCID: PMC7827728 DOI: 10.3390/ph14010055] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2020] [Revised: 12/29/2020] [Accepted: 12/29/2020] [Indexed: 12/12/2022] Open
Abstract
Anthriscus cerefolium (L.) Hoffm. is a plant traditionally used around the globe since antiquity. Although widely used in many traditional medicines in different cultures, from the scientific point of view it is poorly investigated. Glioblastoma, a tumor type with poor prognosis, is the most common and lethal brain tumor in adults. Current therapeutic strategies for glioblastoma include surgery, radiation and chemotherapy. On the other hand, it has been revealed that patients with cancers are highly susceptible to microbial infections due to the invasive nature of cancer treatment approaches. This study was designed to investigate the chemical profile of herba Anthriscii cerefoli methanolic extract by applying UHPLC-LTQ OrbiTrap MS4 analysis and to analyze its anti-glioblastoma and antimicrobial activities. This study revealed that methanolic extract of herba Anthrisc cerefolii contained phenolic acids and flavonoids, with 32 compounds being identified. Anti-glioblastoma activity was investigated in vitro using A172 glioblastoma cell line. The cytotoxic effects of the extract on A172 cells were compared to the same effect on primary human gingival fibroblast (HGF-1) cells. Decreased rate of proliferation and changes in cell morphology were detected upon treatment of A172 cells with the extract. The antimicrobial activity of extract was tested against Staphylococcus aureus and Candida species. The extract was active against the tested bacterium and yeasts, inhibiting free floating cells and microbial biofilms. This study is the first one to provide a detailed description of the chemical profile of A. cerefolium extract dealing with scientific insights into its anti-glioblastoma and antimicrobial activities.

Abstract
Despite the intensive research on radical scavenging action of flavonoids, a systematic study of the thermochemistry for their mono-deprotonated species in aqueous solution is still missing. In this work, reaction enthalpies related to Sequential Proton-Loss Electron-Transfer (SPLET) mechanism were theoretically investigated for all mono-deprotonated forms of nine flavonoids: apigenin, luteolin, fisetin, kaempferol, quercetin, taxifolin, tricetin, tricin and cyanidin. Differences in reaction enthalpies of the first and the second deprotonation can be lower than 10 kJ mol-1, when two successive deprotonations occur in different aromatic rings of the molecule. For neutral flavonoids, thermodynamically preferred deprotonation sites are 4'-OH and 7-OH groups. In cyanidin (cation in native form), preferred second deprotonation site is 5-OH group. In the case of the formation of the preferred dianions, reaction enthalpies of the second proton loss are not affected by the structural distinctions between the flavonoids. In aqueous solution, deprotonated flavonoids show higher tendency to enter SPLET mechanism in comparison to Hydrogen Atom Transfer (HAT) or electron transfer.

Abstract
Cisplatin is an effective chemotherapeutic agent that has pronounced adverse effects. Using flavonoids is currently eliciting considerable interest. During extraction and conditioning, they usually undergo several physical treatments such as heat treatment, although it is not known whether thermal treatment might influence the pharmacological effects of flavonoids such as luteolin-7-O-glucoside (L7G). This study was undertaken to explore the protective role of native and heated L7G against DNA damage and oxidative stress induced by cisplatin. Balb/c mice were administered L7G before a single intraperitoneal injection of cisplatin (10 mg/kg). Animals were sacrificed 24 h after treatment with drugs. The geno-protective role of native and heated L7G was evaluated by comet assay. In addition to monitoring the activities of antioxidant enzymes, levels of malondialdehyde and reduced glutathione were assessed in the liver, kidney, brain, and spleen tissues. The results of the present study demonstrate that both heated and native L7G, at a dose of 40 mg/kg b.w, were able to reduce the genotoxicity of cisplatin. They attenuate the oxidative stress (malondialdehyde, catalase, GPx, SOD, and GSH) and tissue damage (creatinine, IFNγ). Heat treatment did not alter the antigenotoxic effect observed for native L7G and showed similar effects to those of native L7G for all of the evaluated parameters. Our study reveals that L7G attenuates the side effects of anticancer drug and heat treatment did not alter his antigenotoxic and antioxidant the potential.

Abstract
AIMS The present study aims to determine the antimicrobial efficacy of Alphonsea madraspatana leaves extract against selected uropathogens. BACKGROUND The plant Alphonsea madraspatana is an endangered species, reported to exhibit high antimicrobial activity due to the presence of phenolic compounds. Prevalence of high UTI infection and increased cases of bacterial resistance directed for alternative approach to meet the challenge of drug resistance. OBJECTIVE Our objective is to determine antimicrobial efficacy of Alphonsea madraspatana leaves extract against selected uropathogens and subsequent in-silico analysis to predict the underlying mechanism. METHODS Phytochemicals extraction from the dried leaves of Alphonsea madraspatana was performed using solvent gradient technique. All the extracts were subjected to preliminary phytochemical screening using liquid chromatography-mass spectrometry. Antimicrobial activity of the prepared extract was determined against the selected uropathogens using agar diffusion method. Finally, molecular docking study of the selected bio-actives was performed against a representative bacterial resistance enzyme ''DNA Gyrase". RESULTS Methanolic extract exhibits relatively higher antimicrobial activity against the selected strains with Minimum Inhibitory Concentration (MIC) and minimum bactericidal concentration (MBC) of 1.56 ± 1 ug/mL and 6.25 ± 2 ug/mL, respectively. Phytochemical screening showed the presence of 3 flavonoids compounds such as Luteolin-7-O-glucoside, Kaempferol-3-O- rotinoside-7-O-rhamnoside and Genestein-7-O-glucoside. The results of molecular docking shows Luteolin-7-O-glucoside has best docking scores of -8.5 kcal/mol than other ligand molecules. Experimental simulation in presence of DNA Gyrase inhibitors showed lowest MIC and MBC value for E. Coli, which was found to be 1.56 ±1 ug/mL and 6.25±2 ug/mL respectively, support the docking outcomes. CONCLUSION Outcomes of this study suggested that the methanolic extract of this plant shows good anti-microbial potential against resistant uropathogens.

Abstract
Phytochemicals extracted from flowers, roots and bark, leaves, and other plant sources have been used extensively throughout human history with varying levels of efficacy in prevention and treatment of disease. Recently, advanced methods for characterization and clinical use of these materials have allowed modern understanding of their properties to be used as immunomodulatory agents that act by enhancement of endogenous cytoprotective mechanisms, avoiding interference with normal physiologic signaling and highly effective medical treatment with minimal adverse side effects. Simple methods have been identified for improving their biological effects, such as thermal conditioning by heating or freezing-prominent example being heat treatment of lycopene and tetrahydrocannabinol. The present investigation shows improvement of the ability of heat to augment splenocyte proliferation, natural killer (NK) cell activities, and antioxidant capacity of the flavonoid luteolin-7-O-β-glucoside (L7G) in comparison with the native (non heat-treated) molecule, while further demonstrating that both the native and the heat-treated variants exhibit comparable antioxidant properties, as evidenced by their effects in macrophages by inhibition of nitric oxide production and lysosomal enzyme activity in experiments that strengthen lysosomal membrane integrity. Outcomes of these studies suggest that heat-treated L7G shows promise for use in immunotherapy, including anti-cancer regimens, as shown by its improvement of NK cell cytotoxicity.

Antiproliferative and Antibacterial Activities of Cirsium scabrum from Tunisia. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2017; 2017:7247016.

Abstract
Several Cirsium species are known for their uses in traditional medicine and consequently are studied for their phytochemical content and their biological activities. In the framework of a previous study conducted on eight extremophile plants from Tunisia, we highlighted that the crude methanolic extract of C. scabrum, a not investigated thistle, showed moderate but quite selective cytotoxic activity against the cancerous cell line J774 compared to the noncancerous cell line WI38 (IC50 = 11.53 μg/ml on J774, IC50 = 29.89 µg/ml on WI38, and selectivity index = 2.6). In the current study, the partitions of the leaves of C. scabrum were analyzed for their antiproliferative activity on the same cell lines. From the most active petroleum ether partition, we isolated four triterpenoids including lupeol, taraxasterol acetate, and a (1 : 1) mixture of 25-hydroperoxycycloart-23-en-3β-ol and 24-hydroperoxycycloart-25-en-3β-ol. These two cycloartane-type triterpenoids are mostly responsible for this cytotoxic activity. On the other hand, the antimicrobial potential of this plant was also evaluated against 36 microorganisms. The moderate antibacterial activity against 6 Staphylococcus aureus and 2 Dermabacter hominis strains is mainly attributed to the butanol partition whose major compounds are glycosides of flavones.

Abstract
Phloretin-2'-O-glycosyltransferase (P2'GT) catalyzes the last glycosylation step in the biosynthesis of phloridzin that contributes to the flavor, color and health benefits of apples and processed apple products. In this work, a novel P2'GT of Malus x domestica (MdP2'GT) with a specific activity of 46.82 μkat/Kg protein toward phloretin and uridine diphosphate glucose (UDPG) at an optimal temperature of 30 °C and pH 8.0 was purified from the engineered Pichia pastoris broth to homogeneity by anion exchange chromatography, His-Trap affinity chromatography and gel filtration. The purified MdP2'GT was low N-glycosylated and secreted as a stable dimer with a molecular mass of 70.7 kDa in its native form. Importantly, MdP2'GT also exhibited activity towards quercetin and adenosine diphosphate glucose (ADPG), kaempferol and UDPG, quercetin and UDP-galactose, isoliquiritigenin and UDPG, and luteolin and UDPG, producing only one isoquercitrin, astragalin, hyperoside, isoliquiritin, or cynaroside, respectively. This broad spectrum of activities make MdP2'GT a promising biocatalyst for the industrial preparation of the corresponding polyphenol glycosides, preferably for their subsequent isolation and purification. Besides, MdP2'GT displayed the lowest Km and the highest kcat/Km for phloretin and UDPG compared to all previously reported P2'GTs, making MdP2'GT favor phloridzin synthesis the most.

Abstract
According to the World Health Organization, two billion people will be aged 60 years or older by 2050. Aging is a major risk factor for a number of neurodegenerative disorders. These age-related disorders currently represent one of the most important and challenging health problems worldwide. Therefore, much attention has been directed towards the design and development of neuroprotective agents derived from natural sources. These phytochemicals have demonstrated high efficacy and low adverse effects in multiple in vitro and in vivo studies. Among these phytochemicals, dietary flavonoids are an important and common chemical class of bioactive products, found in several fruits and vegetables. Luteolin is an important flavone, which is found in several plant products, including broccoli, pepper, thyme, and celery. Numerous studies have shown that luteolin possesses beneficial neuroprotective effects both in vitro and in vivo. Despite this, an overview of the neuroprotective effects of luteolin has not yet been accomplished. Therefore, the aim of this paper is to provide a review of the available literature regarding the neuroprotective effects of luteolin and its molecular mechanisms of action. Herein, we also review the available literature regarding the chemistry of luteolin, its herbal sources, and bioavailability as a pharmacological agent for the treatment and management of age-related neurodegenerative disorders.

Abstract
Anthriscus sylvestris (L.) Hoffm. is a wild herbaceous plant common in most temperate regions. It has been used traditionally to treat headaches, as a tonic, as antitussive, antipyretic, analgesic and diuretic. The plant contains deoxypodophyllotoxin, which is proven to have antitumor and anti-proliferative effects, anti-platelet aggregation, antiviral, anti-inflammatory and insecticidal activity. Deoxypodophyllotoxin is considered to be the plant’s most important constituent, because of its pharmacological properties and because it can be converted into epipodophyllotoxin, the main raw material for the semisynthesis of the cytostatic agents etoposide and teniposide. This work summarizes for the first time the results related to the botanical description, distribution and habitat, phytochemical and pharmacological properties and emphasizes the aspects for future biotechnological research to establish its utility in the therapeutic arsenal.
