Abstract
This study's main objectives are to evaluate and confirm the effects of the extraction process, operating conditions, solvent type and solvent polarity on the yield and quality of the extracts. Supercritical carbon dioxide (scCO2) and Soxhlet were specially used in this study to extract bioactive chemicals from the seeds of a natural plant known as Plantago ovata. No studies have been published so far regarding the extraction from the seeds of this plant using scCO2.The effects of three operating parameters (pressure, temperature and particle size) on the extraction yield, total phenolic content, total flavonoid content (TFC), total tannin content (TTC) and antioxidant activity were assessed in this study using the Box-Behnken statistical experimental design (BBD). The chemical components in the extracts were separated and identified using gas chromatography mass spectrometry. According to the antioxidant activity results, scCO2 failed to produce bioactive compounds with interesting properties when operated within operating range conditions.

Abstract
The objectives of the study were to conduct phytochemical screening of crude extracts of Cissampelos pareira L. and Lantana camara L. and assessing their biological potentials against protein kinase enzymes, followed by the evaluation of antioxidant and antimicrobial capacities. The n-hexane (A-І, B-І) and ethyl extracts (A-ІІ, B-ІІ) displayed moderate to good antioxidant activity, while the methanol fractions (A-ІІІ, B-ІІІ) showed significant antioxidant activity. Among all the three crude extracts, the ethyl acetate extract (B-II) of L. camara exhibited significant protein kinase inhibitions with remarkable antioxidant potential and was therefore purified through column chromatography. Fraction B-ІІ-2 showed the highest flavonoid contents (735.43), with the most promising protein kinase inhibition exerted by the subtractions B-ІІ-2, B-ІІ-3, B-ІІ-4, and B-ІІ-7. Hence, active fractions were examined through GC-MS for the identification of active constituents, revealing 17 active compounds. In the case of Lantana camara, the ethyl acetate crude extract along with fractions led to the identification of more than thirty compounds, which may be further explored to find a potential lead for drug development.

Abstract
Extracts from Selenicereus monacanthus (synonym: Hylocereus polyrhizus) have received attention due to their potent anti-inflammatory, antioxidant, anticancer, and antidiabetic properties. The current study aims to determine the anti-inflammatory and wound-healing potential of defatted S. monacanthus seed extract (DSMSE). Anti-inflammatory properties of DSMSE on LPS-induced inflammation on THP-1 were determined by measuring the levels of interleukins IL-6, IL-8, and IL-10. Wound healing scratch assay was performed using the human fibroblast (Hs27) cell that assesses the cell migration over 24 h exposure to DSMSE. Administration of DSMSE significantly reduced the LPS-stimulated release levels of IL-6 and IL-8 and significantly increased the levels of IL-10. Treatment with DSMSE showed a significant increase in wound closure with 70% of fibroblast migration. Therefore, the current study showed the anti-inflammatory and wound healing properties of DSMSE reducing inflammatory cytokines (IL-6 and IL-8), increasing IL-10 cytokine, and increasing wound closure at 24 h.

Abstract
Doryopteris raddiana (Presl) Fée, a traditional contraceptive in Mbya culture, lacks scientific scrutiny regarding its chemical composition and contraceptive efficacy. Employing X-ray fluorescence, Fourier-transform infrared spectroscopy, and thermal analysis, we explored the plant's organs. Multielemental analysis excluded toxic elements. Key phytoconstituents identified by gas chromatography-mass spectrometry in the extracts obtained through infusion were glycerine, 1,3-dimethyl propane, and catechol in leaves; glycerine, cis-13-octadecenoic acid methyl ester, and 2-deoxy-D-erythro-pentose in stems and roots. Among these chemicals, glycerine emerged as the sole constituent with contraceptive potential, particularly intravaginally. Extract activity tests conducted on ram spermatozoa exhibited a reduction in the percentage of rapid spermatozoa but no significant impact on total motility, progressive motility, or viability. The reported data would only weakly support the advocated contraceptive action of this fern upon vaginal application, not through the oral administration of its decoction.

Abstract
The realms of natural products and synthetic compounds exhibit distinct chemical spaces that not only differ but also complement each other. While the convergence of these two domains has been explored through semisynthesis and conventional pharmacomodulation endeavours applied to natural frameworks, a recent and innovative approach has emerged that involves the combinatorial generation of libraries of 'natural product-like compounds' (NPLCs) through the direct synthetic derivatization of natural extracts. This has led to the production of numerous NPLCs that incorporate structural elements from both their natural (multiple saturated rings, oxygen content, chiral centres) and synthetic (aromatic rings, nitrogen and halogen content, drug-like properties) precursors. Through careful selection of extracts and reagents, specific bioactivities have been achieved, and this strategy has been deployed in various ways, showing great promise without reaching its full potential to date. This review seeks to provide an overview of reported examples involving the chemical engineering of extracts, showcasing a spectrum of natural product alterations spanning from simple substitutions to complete scaffold remodelling. It also includes an analysis of the accomplishments, perspectives and technical challenges within this field.

Abstract
In this study, analysis of the chemical constituents and bioactivities of the unpolar fractions [petroleum ether (PE) and chloroform (C)] of fruits and leaves of Alpinia oxyphylla Miq. were carried out, as well as the bioactivities of the main compounds nootkatone and valencene. From PE and C fractions of the fruits, and PE fraction of the leaves, 95.80%, 59.30%, and 82.11% of the chemical constituents respectively were identified by GC-MS. Among these identified compounds, nootkatone was the main compound in all of three fractions, while valencene was the second main compound in the PE fractions of the fruits and leaves. The bioactivities results showed that all of the fractions and the major compound nootkatone showed tyrosinase inhibitory, as well as inhibitory effect on NO production in LPS-stimulated RAW264.7 cells. While valencene only presented inhibitory activity on NO production in RAW264.7 cells. The critical genes involved in nootkatone biosynthesis in A. oxyphylla were identified from the public transcriptome datasets, and protein sequences were preliminarily analyzed. Our studies develop the usage of the unpolar fractions of A. oxyphylla, especially its leaves as the waste during its production, and meanwhile provide the gene resources for nootkatone biosynthesis.

Abstract
The phytochemical study of the fruits of Melia azedarach (Meliaceae) led to the isolation and characterisation of two novel natural limonoids1-deoxy- 3, 20-dicinnamoyl-11-methoxy-meliacarpinin (1) and 12β- O- methyl nimbolinin A (2), along with twelve known limonoids. Its structure was identified by 1D- and 2D-NMR, HR-ESI-MS and comparison with published data. The anti-inflammatory effect of the compounds was measured in vitro in RAW 264.7 cells by evaluating the production of NO stimulated by LPS. Compounds 1, 8 and 14 indicated significant anti-inflammatory effect with inhibition rate of 11.76, 8.45 and 6.59 μM, respectively. Limonoid 1 significantly inhibited the production of NO, TNF-α and IL-1β in RAW 264.7 cells. Therefore, limonoid derivative may be a promising source of bioactive metabolite for inflammatory diseases.

Abstract
The discovery of natural molecules with antimicrobial properties has become an urgent need for the global treatment of bacterium and virus infections. Cistus incanus, a Mediterranean shrub species, represents a valuable source of phytochemicals with an interesting wide-spectrum antimicrobial potential. In this study, we analysed the spectrum of molecules composing a commercial hydroalcoholic extract of C. incanus finding ellagitannins as the most abundant. The effect of the extract and its main constituents (gallic acid, ellagic acid and punicalin) was assessed as co-treatment during viral (HSV-1, HCoV-229E, SARS-CoV-2) and bacterial infection (Staphylococcus aureus and Escherichia coli) of cells and as pre-treatment before virus infections. The results indicated a remarkable antiviral activity of punicalin against SARS-CoV-2 by pre-treating both the viral and the host cells, and a major sensitivity of S. aureus to the C. incanus extract compared to E. coli. The present study highlights broad antimicrobial potential of C. incanus extract.

Abstract
Plantago major root extracts were used for analysis by Gas Chromatography-Mass Spectrometry (GC-MS). The anticancer and antibacterial functions of extracts were also investigated. The dichloromethane extract of P. major had the highest inhibitory effect against Salmonella paratyphi (18.00 ± 1.4 mm) at 100 mg/mL concentration. The lowest MIC was also achieved for S. paratyphi treated with dichloromethane extract of P. major (1.5 mg/mL). The minimum MBC (2 mg/mL) was observed for dichloromethane extract of P. major root against S. paratyphi. IC50 values of dichloromethane extracts of P. major root (184.84 μg/mL) against HCT116 were lower than the ethyl acetate and butanol extracts (212.41 μg/mL and 223.93 μg/mL) at 72h. The butanol extract exhibited the most IC50 value on HEK293 (748.19 μg/mL). The biological properties of P. major extracts may be assigned to the presence of numerous compounds detected in GC/MS analysis including n-Hexadecanoic acid, Linolenic acid, Palmitic acid, methyl ester, Stearic acid.

Abstract
Ayurveda, the traditional Indian medical system, has potential applications in early malaria treatment. In an in silico docking study, 50 phytochemicals from two plants Artocarpus lakoocha Roxb. (AL) And Artocarpus heterophyllus Lam. (AH), were examined for their interactions with anti-malarial proteins (PDB IDs: 3BWK, 3BPF, 1LF3). The nucleotide analogue Artemisinin, a current malaria treatment, served as a positive control. Result showed that phytochemicals from AL and AH exhibited binding affinities as high as -9.6 kcal/mol, respectively. Additionally, molecular dynamics simulation for Artocarpin: 3BPF demonstrated stable complexes over 100 ns. Notably, Artocarpin and Quercetin displayed higher binding affinities (up to -9.6 as well as -9.5 kcal/mol, respectively) compared to Artemisinin (-7.5 up to kcal/mol), have shown. Pharmacokinetic predictions indicated the compounds were likely non-carcinogenic, water-soluble and biologically safe. In-vitro analysis using β-Hematin assay supported these findings, suggesting the phytochemicals as Hemozoin pathway inhibitors.

Abstract
Artemisia lactiflora Wall. ex DC. is a traditional Chinese medicinal plant used in the treatment of menstrual and hepatic disorders due to its antioxidant and anti-inflammatory properties. However, its anti-metastatic activity, which is the clinical challenge of lung cancer treatment, has not yet been reported. From the diethyl ether extract of Artemisia lactiflora, the four terpenoids, including dihydroactinidiolide, megastigmatrienone, alpha-curcumene, and dehydrovomifoliol, were the most intense peaks observed using LC-MS/MS, whereas bis (2-ethylhexyl) phthalate was a contaminant. In a transwell assay, the A. lactiflora diethyl ether extract (32 μg/ml) and dihydroactinidiolide (250 μg/ml) markedly inhibited the migration and invasion of non-small cell lung cancer (NSCLC) cells, similar to the standard anti-metastatic drug (capmatinib). Western blot analysis revealed that mesenchymal N-cadherin is downregulated in NSCLC cells under the treatment conditions. The potential anti-metastatic property of dihydroactinidiolide is promising as a new candidate anti-metastatic agent for lung cancer treatment.

Int J Biol Macromol 2024; 261:129576. [PMID: 38253140 DOI: 10.1016/j.ijbiomac.2024.129576] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Revised: 01/15/2024] [Accepted: 01/16/2024] [Indexed: 01/24/2024]
Abstract
There is a pressing need for affordable, abundant, and sustainable sources of proteins to address the rising nutrient demands of a growing global population. The food and agriculture sectors produce significant quantities of waste and by-products during the growing, harvesting, storing, transporting, and processing of raw materials. These waste and by-products can sometimes be converted into valuable protein-rich ingredients with excellent functional and nutritional attributes, thereby contributing to a more circular economy. This review critically assesses the potential for agro-industrial wastes and by-products to contribute to global protein requirements. Initially, we discuss the origins and molecular characteristics of plant proteins derived from agro-industrial waste and by-products. We then discuss the techno-functional attributes, extraction methods, and modification techniques that are applied to these plant proteins. Finally, challenges linked to the safety, allergenicity, anti-nutritional factors, digestibility, and sensory attributes of plant proteins derived from these sources are highlighted. The utilization of agro-industrial by-products and wastes as an economical, abundant, and sustainable protein source could contribute towards achieving the Sustainable Development Agenda's 2030 goal of a "zero hunger world", as well as mitigating fluctuations in food availability and prices, which have detrimental impacts on global food security and nutrition.

Abstract
The cytotoxic effects of Cymbopogon schoenanthus L. aerial part ethanol extract were examined against some cancer cell lines, and HUVEC normal cell lines using MTT assay. The ethanolic extract was prepared by ultrasonic-assisted extraction and analyzed by GC-MS and HPLC. The extract was found to be rich in terpene compounds. The extract proved to be highly selective and effective against breast and prostate cancer cell lines (MDA-MB-435, MCF-7, and DU 145) with IC50 as low as 0.7913 ± 0.14, 12.841 ± 0.21, and 30.51 ± 0.18 µg/ml, respectively. In silico modeling was performed to investigate the binding orientation and affinity of the major identified compounds against Polo-like kinase (PLK1 protein) a cancer molecular target using molecular docking and molecular dynamic whereas eudesm-5-en-11-ol, piperitone, and 2,3-dihydrobenzofuran displayed better binding affinity and stability against PLK1 compared to the reference drug. These findings encourage further in vivo studies to assess the anti-cancer effects of C. schoenanthus extract and its components.

Abstract
The question of whether rare 10,11-seco-lathyranes are natural products or artifacts is thoughtfully considered after a Brønsted acid-mediated chemical conversion of naturally abundant 5/11/3 lathyrane type diterpenes into 10,11-seco-lathyranes was developed. Benefiting from this concise route, a series of 10,11-seco-lathyrane products (1-14) were smoothly synthesized. The conversion may involve an acid promoted cyclopropane ring opening accompanied by a double bond shift with final trapping of carbocation. The ease of this chemical conversion under mildly acidic conditions may imply that the 10,11-seco-lathyranes isolated to date are artifacts. This work not only develops a new modular synthetic strategy for efficient constructing rare 10,11-seco-lathyranes, but also provides a promising bioactive diterpene with excellent effect against the NO production on LPS-induced BV-2 cells.

Abstract
Inhibitory effect of the tested plant oils and their nanoformulation against trypsin and chymotrypsin enzyme extracted from Rhynchophorus ferrugineus, was studies in in vivo and in vitro. In vivo inhibition, the reduction in the trypsin specific activity caused by the bulk oils was greater than that of chymotrypsin enzyme. Compared to control nanoformulation caused significant reduction in the specific activity of trypsin enzyme; however, there were no inhibition effect observed on chymotrypsin enzyme. In vitro bulk oils showed very low inhibitory effect against trypsin enzyme, while they showed strong inhibition activity against chymotrypsin with recording for ginger nanoformulation (half-maximal inhibitory concentration (IC50) =6.83 μg/ml), purple nutsedge (7.632 μg/ml), garden cress (11.52 μg/ml) and castor (16.82 μg/ml), nanoformulation of these oils showed uncompetitive type of inhibition as the Vmax and Km values changed compared to control. In conclusion, nanoformulation of the tested plant oils could be used in the integrated pest management (IPM) programs of the red palm weevil (RPW).

Abstract
This study investigated a wide range of bioactive compounds in bulb and shoot of Allium longisepalum Bertol. from Iran. The organs were first extracted with methanol, followed by hexane, dichloromethane, chloroform, ethyl acetate, and butanol, and phytochemicals in fractions were analysed using GC/MS. Butanol exhibited the highest yield percentages in both organs. Palmitic and oleic acid were found in all fractions, while heptadecene-(8)-carboxylic acid, stearic acid, and myristic acid were detected in at least three fractions. Each fraction contained exclusively unique metabolites found only in itself. Hexane, dichloromethane, and chloroform fractions contained specific metabolites with potential antioxidant, allelopathic, antibacterial, and anti-inflammatory effects. Ethyl acetate and butanol fractions revealed significant compounds that have potential in terms of their anticarcinogenic, anti-inflammatory, hair growth-enhancing, and antimicrobial properties, in addition to containing compounds not previously identified in plants. The study analyzes bioactive compound profiles in A. longisepalum, highlighting its chemical diversity and therapeutic potential.

Abstract
Insecticide resistance is a threat to vector control worldwide. In the Philippines, dengue burden remains significant, thus prioritizing the need to develop eco-friendly control strategies and tools against mosquito vectors. Various Allium species have been found to possess larvicidal activity against dengue-carrying mosquitoes. In this study, the larvicidal activity of the crude extract of Allium ampeloprasum L. (Asparagales: Amaryllidaceae) was studied in concentrations ranging from 1 to 10,000 mg/L against the third (L3) and fourth (L4) larval instars of Aedes aegypti L. Larval mortality at 48 h were subjected to probit analysis and Kruskal-Wallis H test to estimate lethal concentrations and to determine significant means among the groups, respectively. Results show that the crude extract of A. ampeloprasum L. demonstrated larvicidal activity against the L3 and L4 Ae. aegypti L. Concentrations corresponding to 50% mortality (Lethal Concentration 50 [LC50]) among L3 and L4 larvae were estimated at 2,829.16 and 13,014.06 mg/L, respectively. Moreover, 90% mortality (LC90) in the L3 and L4 larvae were estimated at 9,749.75 and 57,836.58 mg/L, respectively. Only 1,000 and 10,000 mg/L for L3, and the 10,000 mg/L for L4, had comparable larvicidal action to the commercial larvicide used as a positive control. The results support the presence of bioactive compounds with larvicidal properties, thus suggesting A. ampeloprasum L. as a potential source of active ingredients for the development of a plant-based larvicide.

Abstract
This study aimed to investigate the chemical composition and toxicity of methanolic extracts of three Algerian propolis collected from Oum el Bouaghi (MEPO), El Harrouch (MEPH) and Collo (MEPC) regions. The chemical profile was characterised by GC-MS. The toxicity of the extracts was tested using brine shrimp model. The GC-MS analysis revealed the presence of ferulic acid (23.8%), pinostrobin chalcone (15.8%) and α-eudesmol (11.3%) as major compounds in MEPO, pinostrobin chalcone (22.2%), 9-octadecenoic acid, methyl ester, (E)- (17.4%), and γ-gurjunenepoxide-(2) (11.7%) were the most abundant components in MEPH, whereas MEPC was dominated by 1-heptatriacotanol (17.8%), pinostrobin chalcone (14.7%), totarol (13.7%) and 9-octadecenoic acid, methyl ester, (E)- (13.0%). The brine shrimp lethality test indicated that the extracts had moderate toxicity in which MEPC exhibited the highest activity with LC50 of 201.61 ± 7.27 µg/mL. All extracts showed no toxicity at 25 µg/mL concentration and below.

Abstract
Endophytic fungi are essential sources of various bioactive natural compounds. The present study is aimed to investigate the chemical composition and antioxidant compounds of the root endophytic aquatic hyphomycetous fungi Tetracladium setigerum isolated from the roots of Barberries aristata growing in the riparian area of Nainital, Kumaun Himalaya. The chemical profiling was done by GC-MS analysis. The presence of 32 compounds characterised the fungal extract. 1, 2-Benzenedicarboxylic acid, diethyl ester; Bis(2-ethylhexyl) phthalate; and Bicyclo [3.2.1]octan-4-on-1-carbonsaeure,6-(6,10dimethyl-1,5,9-undecatrien-2-yl)-8-methyl-, ethyl ester were reported as major compounds in the ethyl acetate extract of T. setigerum. The antioxidant capacity of the extract was assessed by DPPH, MCA, and FRAP assay. In antioxidant analysis, the ethyl acetate extract of T. setigerum presents IC50, 42.34 µg/ml, and 46.90 µg/ml using DPPH and MCA, respectively. The tested extract also showed effective antioxidant activity 436.71 ± 9.3 mg AAE/g of the dry extract using FRAP assay.

Abstract
Chemical investigation of the antimalarial medicinal plant Clerodendrum polycephalum led to the isolation of five new diterpenoids, including ajugarins VII-X (1-4) and teuvincenone K (5), along with four known compounds, namely, 12,16-epoxy-6,11,14,17-tetrahydroxy-17(15 → 16)-abeo-5,8,11,13,15-abietapentaen-7-one (6), methyl pheophorbide A (7), loliolide (8), and acacetin (9). The chemical structures of the new compounds were elucidated using NMR spectroscopy, mass spectrometry, circular dichroism, as well as density functional theory calculations. All compounds were evaluated for in vitro activity against Plasmodium falciparum 3D7 malaria parasites with methyl pheophorbide A (7) showing the strongest activity (IC50 4.49 μM). Subsequent in vivo testing in a Plasmodium berghei chemosuppression model showed that compound 7 significantly attenuated peripheral blood parasitemia, leading to 79% and 87% chemosuppression following oral doses at 10 and 20 mg/kg, respectively.

Abstract
A rapid untargeted UHPLC-Q-TOF-ESI-MS/MS-Based metabolomic profiling of the medicinal plant Entada abyssinica was performed. A total of 18 metabolites were detected, of which 10 could not be identified. Based on this result, an extensive chemical investigation of the CH2Cl2-MeOH (1:1) extract of this plant was carried out, leading to the isolation of a new ceramide, named entadamide (1), together with nine known compounds: monomethyl kolavate (2), 24-hydroxytormentic acid (3) chondrillasterol (4), 3-O-β-D glucopyranosylstigmasterol (5), 3-O-β-D glucopyranosylsitosterol (6), quercetin 3'-methylether (7), 2,3-dihydroxypropyl icosanoate (8), 2,3-dihydroxy-propyl 23-hydroxytricosanoate (9) and 2,3-dihydroxy-propyl 24-hydroxytetracosanoate (10). Their structures were elucidated by the analyses of their spectroscopic and spectrometric data (1D and 2D NMR, and HRESI-MS) in comparison with those reported in the literature. Furthermore, the crude extract and some isolated compounds were tested against non-ciprofloxacin resistant strains viz, Pseudomonas aeruginosa (ATCC 27853), Escherichia coli (ATCC 25922), Samonella thyphi (ATCC 19430) and Samonella enterica (NR4294). The tested samples demonstrated significant activity against all the tested bacteria (MIC values: 3.12-12.5 μg/mL).

Abstract
Plumbago europaea L. belongs to the family Plumbaginaceae, which has many medicinal and nutritional applications. It is among the significant medicinal herbs used widely in folk medicine in Syria to treat skin diseases such as eczema and psoriasis. There are no previous studies of the aerial parts' essential oils of this plant. So, herein we report on determining the chemical composition of essential oils extracted from the aerial parts of P. europaea L., which were collected from a mountainous area in Latakia Province, Syria, by utilising the GC-MS technique. The major compounds identified in the flower's essential oils were: plumbagin (32.4%), hexadecanoic acid (13.79%), heneicosane (9.03%) and 2,6-di-tert-butyl-4-ethylphenol (8.40%). While in the leaves' essential oils were phytol (17.97%), dibutyl phthalate (15.45%), heneicosane (6.91%) and hexahydrofarnesyl acetone (6.72%). In addition, according to the published literature, most of the identified compounds have been reported to exhibit significant biological activities.

Abstract
Salvia dumetorum essential oil (SDEO) was obtained using a Clevenger apparatus by hydrodistillation approach. The chemical composition of the essential oil was determined by GC-MS analysis. In this study SDEO was screened for its antibacterial activity against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Candida albicans and the amount of biofilm formed by Streptococcus mutans bacteria. For the first time the chemical composition of SDEO growing in Central Kazakhstan was established. The results obtained from GC-MS showed the predominance of sesquiterpenoids (54.15%). The antibacterial study results showed that SDEO exhibited strong antibacterial activity against B. subtilis and S. aureus in vitro and also demonstrated an inhibitory effect on S. mutans biofilm formation on 1% sucrose medium. During the study, no antibacterial activity was detected against E. coli and C. albicans. These results demonstrated that SDEO can be used in the development of new antibacterial and anti-caries therapeutic dental products.

Comparative metabolomic profiling of Cupriavidus necator B-4383 revealed production of cupriachelin siderophores, one with activity against Cryptococcus neoformans. Front Chem 2023; 11:1256962. [PMID: 37693169 PMCID: PMC10484230 DOI: 10.3389/fchem.2023.1256962] [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: 07/11/2023] [Accepted: 08/07/2023] [Indexed: 09/12/2023] Open
Abstract
Cupriavidus necator H16 is known to be a rich source of linear lipopeptide siderophores when grown under iron-depleted conditions; prior literature termed these compounds cupriachelins. These small molecules bear β-hydroxyaspartate moieties that contribute to a photoreduction of iron when bound as ferric cupriachelin. Here, we present structural assignment of cupriachelins from C. necator B-4383 grown under iron limitation. The characterization of B-4383 cupriachelins is based on MS/MS fragmentation analysis, which was confirmed by 1D- and 2D-NMR for the most abundant analog (1). The cupriachelin congeners distinguish these two strains with differences in the preferred lipid tail; however, our rigorous metabolomic investigation also revealed minor analogs with changes in the peptide core, hinting at a potential mechanism by which these siderophores may reduce biologically unavailable ferric iron (4-6). Antifungal screening of the C. necator B-4383 supernatant extract and the isolated cupriachelin analog (1) revealed inhibitory activity against Cryptococcus neoformans, with IC50 values of 16.6 and 3.2 μg/mL, respectively. This antifungal activity could be explained by the critical role of the iron acquisition pathway in the growth and pathogenesis of the C. neoformans fungal pathogen.

Sánchez-Hernández E, Martín-Ramos P, Niño-Sánchez J, Diez-Hermano S, Álvarez-Taboada F, Pérez-García R, Santiago-Aliste A, Martín-Gil J, Diez-Casero JJ. Characterization of Leptoglossus occidentalis Eggs and Egg Glue. INSECTS 2023; 14:396. [PMID: 37103211 PMCID: PMC10143709 DOI: 10.3390/insects14040396] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Revised: 04/16/2023] [Accepted: 04/18/2023] [Indexed: 06/19/2023]
Abstract
The western conifer seed bug (Leptoglossus occidentalis Heidemann, 1910, Heteroptera: Coreidae) has a significant economic impact due to the reduction in the quality and viability of conifer seed crops; it can feed on up to 40 different species of conifers, showing a clear predilection for Pinus pinea L. in Europe. Its incidence is especially relevant for the pine nut-producing industry, given that the action of this pest insect can reduce the production of pine nuts by up to 25%. As part of ongoing efforts aimed at the design of control strategies for this insect, this work focuses on the characterization (by scanning electron microscopy-energy-dispersive X-ray spectroscopy, Fourier-transform infrared spectroscopy, and gas chromatography-mass spectroscopy, GC-MS) of the compounds released by these insects during oviposition, with emphasis on the adhesive secretion that holds L. occidentalis eggs together. Elemental analysis pointed to the presence of significant amounts of compounds with high nitrogen content. Functional groups identified by infrared spectroscopy were compatible with the presence of chitin, scleroproteins, LNSP-like and gelatin proteins, shellac wax analogs, and policosanol. Regarding the chemical species identified by GC-MS, eggs and glue hydromethanolic extracts shared constituents such as butyl citrate, dibutyl itaconate, tributyl aconitate, oleic acid, oleamide, erucamide, and palmitic acid, while eggs also showed stearic and linoleic acid-related compounds. Knowledge of this composition may allow advances in new strategies to address the problem caused by L. occidentalis.

Abstract
Panchvalkal kwath (PK) is a bark formulation of five pharmacologically important plants, i.e., Ficus benghalensis, Ficus racemosa, Ficus religiosa, Thespesia populnea, and Ficus lacor. The Ayurvedic formulation is being used since ancient times to cure diabetes, bacterial infections and heal wounds. The present study aims to identify the metabolite profiles of PK which could explain its properties and its mode of action against specific diseases and disorders. The aqueous extract of Panchvalkal is prepared through a hot maceration process. The extract is subjected to preliminary identification of phytoconstituents and FTIR spectroscopy to recognize functional groups. GC-MS analysis reveals that the extract is enriched with 24-Norursa-3,12-diene (25.16%); Lup-20(29)-en-3-one (16.76%); 2-methyl-3-(4-propan-2-ylphenyl) propanal (7.04%); 2-(hydroxymethyl)-2-nitropropane-1,3-diol (11.21%) and 3,5-dihydroxy-6-methyl-2,3-dihydropyran-4-one (4.15%). The presence of three new phytocompounds that are 4-(hydroxymethyl)-7-methyl-1,3-dioxepane-5,6-diol; 1-(4-isopropylphenyl)-2-methylpropylacetate and 4,4,6 A,6B,8A,11,11,14B-octamethyl-1,4,4A,5,6,6A,8,8a,910,11,12,12a,12b,13,14,14a,14b-ctadecahydro-3(2H)-picenone are detected in the extract. Metabolite profiles of the extract also constitute isoeugenol, stigmasterol, ergosterol, ocimene, myrcene, squalene, sphingosine, betulin, methyl ferulate and cis-jasmone, which are unraveled by 1 D 1H and 2 D 1H-13C HSQC NMR spectroscopy. This article focuses on the presence of different phytocompounds in PK in order to demonstrate its efficacy as a therapeutic formulation for a variety of diseases.

Abstract
Syzygium aromaticum L. is an aromatic plant with a significant amount of essential oil (EO), which is used in food, medicine, for flavoring, and in the fragrance industry. The purpose of this study was to comparatively evaluate the chemical composition, yield, and antioxidant and antifungal activities of Syzygium aromaticum essential oils extracted by the conventional hydro-distillation, steam distillation, and the emerging superheated steam distillation methods. It was noticed that the extraction methods significantly influenced the yield, chemical composition, and antioxidant and antimicrobial activities of essential oils. The maximum yield was obtained using superheated steam distillation, followed by hydro-distillation and steam distillation. The antioxidant potential of EO extracts was evaluated following the scavenging of 2,2-dipenyl-1-picrylhydrazyl radicals, hydrogen peroxide scavenging activity and ferric reducing power assays. Results revealed that EO extracted superheated steam distillation exhibited the highest antioxidant activity. GC-MS analysis depicted eugenol (47.94–26.50%) and caryophyllene (20.24–9.25%) as the major compounds of Syzygium aromaticum EOs. The antimicrobial activity of EO extracts was evaluated, via the resazurin microtiter plate assay, microdilution broth assay, and disc diffusion methods, against normal and food pathogenic bacterial and fungal strains. After comparative evaluation, it was observed that superheated steam extracted EO exhibited the highest antimicrobial potential. Overall, methodical evaluation disclosed that superheated steam distillation is an effective method to extract EOs from plant sources, with greater yield and promising biological activities.

Abstract
The essential oils from roots, branches, leaves and bark of Magnolia sumatrana var. glauca (Blume) Figlar & Noot and Magnolia hypolampra (Dandy) Figlar were extracted by ultrasonic-assisted extraction and the chemicals were determined by gas chromatography-mass spectroscopy (GC-MS). The major constitutes of M. sumatrana var. glauca were trans-cinnamaldehyde (27.55%), caryophyllene (1.20-10.14%), (+)-bulnesol (9.70%), α-caryophyllene (2.35-6.35%), α-eudesmol (1.08-6.17%). M. hypolampra was characterized by the presence of safrole (0.18-35.01%), (+) cycloisosativene (18.70%), oxirane, hexadecyl- (0.72-12.79%), β-cubebene (1.53-8.90%), (Z)-14-tricosenyl formate (8.65%). This is the first study of the composition of essential oils from the roots, branches and bark of M. sumatrana var. glauca and the roots of M. hypolampra, and some compounds were being described for the first time. Combined with present results and literatures, phytochemicals may be affected by multi-factors such as organs, growing location, and extraction methods, providing more approaches for further exploration of the non-wood resources of forestry species.
