Abstract Objectives To develop a precision nutrition knowledge database, with the aim to provide individualized and actionable dietary recommendations to help prevent disease. However presently, dietary phytochemicals are poorly represented in current metabolomic databases. To address this gap, we are building a cloud-based knowledge database (KDB) named “The Metabolome of Food” (MetaboFood®) which focuses on phytochemical compositional, metabolite and pathway data. Methods MetaboFood® features P-MetDB®, a database in static tabular form, of nutritionally relevant phytochemicals and their metabolites derived from systematic literature reviews of 17 commonly consumed phytochemical-rich foods, matched to InChI key, physical and chemical properties (mass, formula) and database identifiers (i.e., PubChem ID, KEGG ID, SMILES etc.). To build MetaboFood®, information about metabolic pathways and diseases associated with these foods have been extracted from various pathway databases using APIs that these databases provide. Information can be searched in MetaboFood® and results are explored in a highly visual and interactive way, in the form of self-organizing maps, node-link diagrams, Sankey diagrams and other visual analytics techniques. Results MetaboFood® captures data on foods, their phytochemical compositions, human and microbial metabolites, and pathway and diseases linkages. Information in MetaboFood® facilitates both hypothesis generation and hypothesis testing relative to food and pathway analysis. Initial use of this database identifies significant interactions between polyphenol rich foods and numerous metabolic networks. Conclusions MetaboFood® builds on traditional food composition databases by integrating biochemical and disease pathway data with diet metabolites. A key to moving forward is building data richness, enabling greater connections between diet and health.

The geographical location of Morocco and the diversity of its topography ensure a high variability of climate conditions, ranging from humid to Saharan, and extending through subhumid, arid, and semi-arid stages. This variability offers a high floristic diversity, while the medical use of these phytochemicals has not been fully explored. Advanced computer-aided drug discovery utilizes chemical biology to accelerate the study of phytochemicals at the molecular level and discover novel therapeutic pathways. Currently, there is no online resource for phytochemicals in Morocco. Therefore, it is of interest to describe the Moroccan Phytochemicals Database (MPDB), accessible, featuring over 600 phytochemicals derived from journal articles and other reports. The web interface of the database, which is simple and easy to use, provides each phytochemical's reference, plant sources, 3D structures, and all related information. Furthermore, we provide direct links to commercially available analogs from Mcule. In addition, we provide the results of the first virtual screening against cardiovascular targets. We present these data to facilitate further exploration and exploitation of Morocco's rich phytochemical resources, and to contribute to the global understanding and application of these compounds in the medical and scientific communities.

Background: Phytochemicals are obtained from various plants and used for the treatment of diseases as both traditional and modern medicines. Poor bioavailability of phytochemicals is a major concern in applying phytochemicals as a therapeutic agent. It is, therefore, necessary to understand the metabolism and pharmacokinetics of phytochemicals for its implication as a therapeutic agent. Methods: Articles on the metabolism of phytochemicals from the PubMed database. The articles were classified into the digestion, absorption, metabolism, excretion, toxicity, and bioavailability of phytochemicals and the effect of gut microbiota on the metabolism of phytochemicals. Results: The metabolism of each phytochemical is largely dependent on the individual's digestive ability, membrane transporters, metabolizing enzymes and gut microbiota. Further, the form of the phytochemical and genetic make-up of the individual greatly influences the metabolism of phytochemicals. Conclusion: The metabolism of phytochemicals is mostly depended on the form of phytochemicals and individualspecific variations in the metabolism of phytochemicals. Understanding the metabolism and pharmacokinetics of phytochemicals might help in applying plant-based medicines for the treatment of various diseases.

Highlights1. Heart failure preserved ejection fraction increases the mortality rate every year.2. Definitive therapy for HFpEF is not well identified.3. Crocus sativus phytochemical has anti-inflammatory and cardioprotective effects due to iNOS and PDE-9 inhibition. AbstractBackground: Heart failure preserved ejection fraction (HFpEF) is a complex disease associated with metabolic disease as a risk factor. A previous study found an association between iNOS and PDE-9 with inflammation and myocardial fibrosis in HFpEF. Objective: This study aimed to identify the potential phytochemicals of Crocus sativus (Saffron) that can inhibit protein iNOS and PDE-9 based on a molecular docking study. Material and Method: A total of fifty phytochemicals were obtained from Dr. Duke’s Phytochemical Database and IJAH IPB. Those phytochemicals were screened by using the PyRx application and followed with Lipinski’s Rule of Five screening by using SWISS Adme. Ten phytochemicals with lowest binding energy for each protein were docked and visually analyzed using Autodock 4.2 and BIOVIA Discovery Studio Visualizer 2016. Results: The best binding energy between protein-phytochemicals were -9.17 kcal/mol and -8.55 kcal/mol for iNOS and -9.17 kcal,/mol and -9.08 kcal/mol for PDE-9. Conclusion: Delphinidine and malvidin are the recommended inhibitors against iNOS and PDE-9 and must be investigated in further research.

Background: Sri Lanka offers a huge diversity of flora with a large proportion of those being endemic to the island. Both the endemic and native plants species serve as a rich bank of phytochemicals. Method: In this study, “Sri Lankan Flora” an online web-based information system of phytochemical compounds isolated from the flora of Sri Lanka was proposed. Results: The database contained 3D structures of those compounds, calculated quantitativestructure- activity relationship (QSAR) data and the GROMOS 54a7 force field parameters for each and every compound. The manually curated chemical structures, activities and force field parameters provide a possible direct avenue for computer-aided drug discovery. The present study is a continuing project with a wider goal of building up a database, not only for assisting the computeraided drug designing process, but also for other chemical applications, as the database includes structural, physical, chemical and dynamic properties of chemical compounds of the flora of Sri Lanka. The database is freely accessible at http://science.cmb.ac.lk/tools/slflora.

Infection of extreme acute respiratory syndrome coronavirus 2 triggers Coronavirus disease 2019 (COVID-19). COVID-19 has adverse consequences on persons and is getting worse in all nations. The aim of this research is to investigate the development of in-silico approach of phytochemical inhibitor used to fight COVID-19 pathway inhibition. In medicinal plants, there are many phytochemicals, however the bioactive mechanism remains uncertain. In-silico experiments offer additional evidence to confirm the inhibition of medicinal plants. Molecular docking was used to evaluate phytoconstituents from Allium cepa as COVID-19 M-pro inhibitor, compared to remdesivir (standard drug). STITCH database used to predict the interaction network process of the most potential compound. The most potential compound was oleanolic acid. Oleanolic acid with a docking score of -9.20 kcal/mol was reported as anti-COVID-19 activity. This docking score was higher than remdesivir. Oleanolic acid interacted with GLU166, CYS44, HIS41, and THR25 via the hydrogen bond. From STITCH Database, oleanolic acid interact with CASP-9, XIAP, CASP-3 signalling pathway. Oleanolic acid from Allium cepa has been reported as a possible COVID-19 M-pro inhibitor and should be studied in future studies. The experiment indicates that phytochemical inhibitor can be helpful in the medication of COVID-19.

Salvia mirzayanii Rech. f. & Esfand is an endemic herbaceous plant belonging to the Lamiaceae family. The plant grows in the center and south of Iran and is broadly used in folk medicine. This review focuses on phytochemical and pharmacological data of S mirzayanii. Databases such as PubMed, Scopus, Web of Science, Scientific Information Database (Iranian database involving English and Persian articles), and Google Scholar were searched for terms “ Salvia mirzayanii,” “Iranian sage,” “ Marv-e-Talkh,” and “ Moor-e-Talkh” in both Persian and English up to December 10, 2013. In line with the ethnopharmacological uses, antioxidant, immunomodulatory, anti-inflammatory, antimicrobial, and insecticidal activities of different preparations of S mirzayanii have been shown in recent studies. The antimicrobial activity against human pathogenic strains has mainly been attributed to the essential oil of S mirzayanii, which in numerous analyses has been investigated either in plants of different origin or prepared by differing extraction methods. Despite the studies on antioxidant or antimicrobial activities, profound research on the toxicity or clinical properties of the herb is missing.

Withania somnifera has been used for a long time in traditional medicine. Its crude extract, dried powder, and purified metabolites from mature plants have shown promising therapeutic potential. To further investigate its potential, the detection of phytochemicals with anticancer and antimicrobial properties in the vegetative stage is essential. Hence, this study was done to identify phytochemical constituents using GC-MS analysis for anticancer and antimicrobial activities in the vegetative stage from methanolic extracts of stem, leaf, and root in W. somnifera. The air-dried plant parts were extracted with methanol at low pressure to concentrate using a rotary evaporator at 40°C. To identify phytochemicals, Shimadzu GCMSQP2010, Japan, was used with the NIST107.LIB database. The GC-MS identified 35 unique phytochemical peaks at the vegetative stage in W. somnifera. In leaves, the antibacterial phytochemicals included cyclotrisiloxane, hexamethyl, with a high abundance, and cyclohexasiloxane, dodecamethyl, with the least abundance. In roots, the phytochemicals 2,2-dimethoxybutane, with high abundance, and cathinone, with least abundance, were found to have antibacterial properties, whereas trans-2,3-epoxyoctane, with high abundance, and 2,2-dimethoxybutane, with least abundance, were found to have anticancer properties. In stem, the antibacterial phytoconstituents octasiloxane, 1,1,3,3,5,5,7,7,9,9,11,11,13,13,15,15-hexadecamethyl, and benzenemethanol, alpha.-(1-aminoethyl), were found to be the most abundant and least abundant, respectively, while arabinitol and pentaacetate had both anticancer and antibacterial activities. At the vegetative stage, GC-MS studies of stem, leaf, and root parts revealed the occurrence of potential phytochemicals for antibacterial and anticancer activities in W. somnifera.

Aim: Phytocompounds are important due to their uniqueness, however, only few reach the development phase due to their poor pharmacokinetics. Therefore, preassessing the absorption, distribution, metabolism, excretion and toxicity (ADMET) properties is essential in drug discovery. Methodology: Biologically diverse databases (Phytochemica, SerpentinaDB, SANCDB and NuBBEDB) covering the region of India, Brazil and South Africa were considered to predict the ADMET using chemoinformatic tools (Qikprop, pkCSM and DataWarrior). Results: Screening through each of pharmacokinetic criteria resulted in identification of 24 compounds that adhere to all the ADMET properties. Furthermore, assessment revealed that five have potent anticancer biological activity against cancer cell lines. Conclusion: We have established an open-access database (ADMET-BIS) to enable identification of promising molecules that follow ADMET properties and can be considered for drug development.

Withanias omnifera also known as Indian ginseng is commonly found in India and other Southeast Asian countries. Various parts of this plant have been used as herbal medicine to treat a variety of diseases. However, there is a lacuna in the profiling of phytochemical constituents present in the different parts of the plant at reproductive stage. To identify phytochemicals present in the methanolic extracts of leaf, root, and stem parts of W. somnifera at reproductive stage using GC-MS analysis. Methods: The airdried parts of plant (leaf, stem and root) were extracted with methanol and concentrated under reduced pressure at 40°C using a rotary evaporator. The GCMSQP2010, Shimadzu, Kyoto, Japan with headspace sampler (AOC-20s) and autoinjector (AOC-20i), was used for sample analysis. The phytochemicals were identified with the database provided by National Institute Standard and Technology (NIST11LIB). The GC-MS analysis of leaf, root, and stem methanolic extracts of W. somnifera, revealed a total of eighty-two unique phytochemical peaks in the reproductive stage of the plant. Phytochemicals with antimicrobial and anticancer properties were identified in all the parts. In leaf, 2-pentanone, 5-chloro- was found to be most abundant and 2,5-dimethoxy-4-propoxy-. beta.-methyl-.beta.-nitrostyrene least abundant with antimicrobial nature, whereas, benzene, 1,1'-(1,2-ethenediyl)bis[2-methyl- was found to be most abundant and dibenzo[a,e]cyclooctene, 5,6,11,12-tetrahydro- least with anticancer property. In roots, the most abundant was benzoic acid, 3-methyl-2-trimethylsilyloxy-, trimethylsilyl ester and tris(trimethylsilyl)hydroxylamine the least abundant were identified to be antimicrobial, whereas high abundance uleine and low abundance 2-{4-[2-(4-methoxymethylphenyl)vinyl]phenyl}propan-2-olwere identified to be anticancer. In stem, acetohydroxamic acid was found to be most abundant and trans2,3,6-trimethoxy-b-methyl-b-nitrostyrene least abundant for antimicrobial nature, whereas 3-acetoxy-2,3'-bibenzo[b]thiophene was found to be anticancer phytochemical. In this study, phytochemicals with antimicrobial and anticancer properties were identified in leaf, root and stem parts of W. somnifera at reproductive stage.

BACKGROUND: There is a strong negative relationship between high-density lipoprotein cholesterol (HDL-C) and the risk of cardiovascular disease (CVD). Cholesterol ester transfer protein (CETP) is a glycoprotein transporter that transfers cholesterol esters to very low-density lipoprotein and low-density lipoprotein cholesterol (LDL-C). The CETP inhibitor is a new strategy against CVD because of its ability to increase HDL-C. Various Indonesian plants have not been optimally used, and in silico phytochemical screening of these plants showing potential as CETP inhibitors is still limited. AIM: This study for exploring Indonesian phytochemicals as CETP inhibitors for new CVD treatments. METHODS: We screened 457 phytochemicals registered in the herbal database and met Lipinski’s rule of five. Their molecular structures were downloaded from the PubChem database. The three-dimensional structures of CETP and dalcetrapib (the CETP inhibitor standard) were obtained from a protein data bank (http://www.rcsb.org/pdb/) with the 4EWS code and ZINC database with the ZINC03976476 code, respectively. CETP–dalcetrapib binding complexes were validated 5 times using AutoDock Vina 1.1.2 software. Interactions between CETP and phytochemicals were molecularly docked with the same software and visualized using Pymol 1.8× software. RESULTS: Dalcetrapib had a docking score of −9.22 kcal/mol and bound to CETP at Ser230 and His232 residues. The 11 phytochemicals had lower binding scores than dalcetrapib, but only L-(+)-tartaric acid, chitranone, and oxoxylopine could interact with CETP at the Ser230 residue. These are commonly found in Tamarindus indica, Plumbago zeylanica, and Annona reticulata, respectively. CONCLUSION: L-(+)-Tartaric acid, chitranone, and oxoxylopine show potential as CETP inhibitors in silico.

The rhizomes of Aglaomorpha coronans is used to cure back pain by the local people of Lamjung district. The medicinal value depends on the presence of biologically active phytochemicals with drug like properties. Phytochemical evaluation of A. coronans of Nepalese origin has not been reported yet. Hence, the present study is focused on the phytochemical analysis, evaluation of antioxidant, antibacterial activities of various extracts and GC-MS profiling of ethyl acetate extract. The rhizomes were extracted with the hexane, chloroform, ethylacetate, methanol and 50% aqueous methanol. Phytochemical screening of ethyl acetate, methanol and 50% aqueous methanol extracts showed the presence of phenolics, flavonoids, tannins and sugar. Their total content as well as antioxidant activity were determined. The highest amounts of phenolics, flavonoids and tannins were detected in the ethyl acetate extract (292.144±1.829 mg GAE/g, 322.904±3.942 mg CE/g, 516.666±0.423 mg TAE/g). The highest amounts of sugars were detected in the methanol extract (205.649±0.169mg GE/g). In DPPH radical scavenging assay, ethyl acetate extract showed the highest activity (IC50 37.545 μg/ml). The chloroform, ethyl acetate and methanol extracts showed antibacterial activity against S. aureus. GC-MS analysis of ethyl acetate extract showed the presence of more than 20 compounds. However, 9 compounds, mainly polyol, low molecular weight phenolic acids and terpenes/sterols were identified by comparing the mass fragmentation pattern of each compound with the standard NIST mass spectral database. The presence of 3,4-dihydroxy benzoic acid, Olean-13(18)-ene and β-sitosterol justifies the anti-inflammatory and analgesic properties of A. coronans in traditional medicine.

Pain in cancer therapy is a common condition and there is a need for new options in therapeutic management. While phytochemicals have been proposed as one pain management solution, knowledge of their utility is limited. The objective of this study was to perform a systematic review of the biomedical literature for the use of phytochemicals for management of cancer therapy pain in human subjects. Of an initial database search of 1,603 abstracts, 32 full-text articles were eligible for further assessment. Only 7 of these articles met all inclusion criteria for this systematic review. The average relative risk of phytochemical versus control was 1.03 [95% CI 0.59 to 2.06]. In other words (although not statistically significant), patients treated with phytochemicals were slightly more likely than patients treated with control to obtain successful management of pain in cancer therapy. We identified a lack of quality research literature on this subject and thus were unable to demonstrate a clear therapeutic benefit for either general or specific use of phytochemicals in the management of cancer pain. This lack of data is especially apparent for psychotropic phytochemicals, such as theCannabisplant (marijuana). Additional implications of our findings are also explored.

Oral mucosal lesions have many etiologies, including viral or bacterial infections, local trauma or irritation, systemic disorders, and even excessive alcohol and tobacco consumption. Folk knowledge on medicinal plants and phytochemicals in the treatment of oral mucosal lesions has gained special attention among the scientific community. Thus, this review aims to provide a brief overview on the traditional knowledge of plants in the treatment of oral mucosal lesions. This review was carried out consulting reports between 2008 and 2018 of PubMed (Medline), Web of Science, Embase, Scopus, Cochrane Database, Science Direct, and Google Scholar. The chosen keywords were plant, phytochemical, oral mucosa, leukoplakia, oral lichen planus and oral health. A special emphasis was given to certain plants (e.g., chamomile, Aloe vera, green tea, and coffea) and plant-derived bioactives (e.g., curcumin, lycopene) with anti-oral mucosal lesion activity. Finally, preclinical (in vitro and in vivo) and clinical studies examining both the safety and efficacy of medicinal plants and their derived phytochemicals were also carefully addressed.

Background. Paeoniae Radix Alba (PRA), the root of the plant Paeonia lactiflora Pall., has been suggested to play an important role for the treatment of asthma. A biochemical understanding of the clinical effects of Paeoniae Radix Alba is needed. Here, we explore the phytochemicals and therapeutic mechanisms via a systematic and comprehensive network pharmacology analysis. Methods. Through TCMSP, PubChem, GeneCards database, and SwissTargetPrediction online tools, potential targets of active ingredients from PRA for the treatment of asthma were obtained. Cytoscape 3.7.2 was used to determine the target of active ingredients of PRA. Target protein interaction (PPI) network was constructed through the STRING database. The Gene Ontology (GO) biological process and Kyoto Encyclopedia of Genes and Genes (KEGG) pathway enrichment analysis were analyzed through the biological information annotation database (DAVID). Results. Our results indicate that PRA contains 21 candidate active ingredients with the potential to treat asthma. The enrichment analysis of GO and KEGG pathways found that the treatment of asthma by PRA may be related to the process of TNF (tumor necrosis factor) release, which can regulate and inhibit multiple signaling pathways such as ceramide signaling.

The ethnomedicinal function of several cucurbit species (cucumber, squash, melon, gourd, etc.) on diseases (i.e. diabetes, microbial infections, cancer, etc.), and as free radical scavengers have been reported. However, there remains infinitesimal record on citron watermelon broad use, which reflects the reason for wide oversight of underutilization, from lack of recognition for functional food crop development and commercialization. The objective of this study focus towards identifying the natural phytochemicals of C. lanatus on water melon molecules online database for insilico computational approach to screened for suitable antidiabetic lead, and construction of phylogenetic relatedness of target Type 2 Diabetes Mellitus proteins was conducted to predict reoccurrence of insilico analysis output with other homologous target proteins. The T2DM protein targets, phytochemical and standard inhibitory drugs are mined from different databases. Insilico docking analysis, and adme/toxicity profiling was virtually screened for the best fit. In additionally, phylogenetic relationship of the target proteins was aligned and construction with other homologous protein targets to predict the reoccurrence confidence of results on compounds. Seventeen phytochemicals out of the nineteen potential drug candidates substantially passed the profiling test. Also, homologous protein targets with > 90% bootstrap confidence are likely to produce a reoccurring insilico result. Thus, these phytochemicals fulfil all the enlisted criteria and it is suggestively determined to be suitable for the development of potent antidiabetic drugs. It is evident that phytochemicals from Citrullus lanatus produced satisfactory insilico output, and this reflect it to be a probable reservoir containing other potential therapeutic drug candidates for antidiabetic drug discovery and development.

Background Triple-negative breast cancers are defined as tumors that lack the expression of the estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). It exhibits unique clinical and pathological features, is highly aggressive, and has a relatively poor prognosis and poor clinical outcome. Objective To identify a novel drug target protein against triple-negative breast cancer (TNBC) and potential phytochemical lead molecules against novel drug targets. Methods In this study, we retrieved TNBC samples from NGS and microarray datasets in the Gene Expression Omnibus database and employed a combination of differential gene expression studies, protein-protein interaction analysis, and network topology investigation to identify the target protein. Using molecular docking and molecular dynamics simulation studies, followed by Molecular Mechanics with Generalised Born Surface Area solvation, a potential lead molecule was identified. Result The androgen receptor (AR) was found to be the target protein, and 2-hydroxynaringenin was discovered to be a possible phytochemical lead molecule to combat TNBC. Upregulated genes with LogFC > 1.25 and P-value < 0.05 from the TNBC gene expression dataset were given to STRING tool to investigate the network topology, and androgen receptor (AR) was found to be an appropriate hub gene in the protein-protein interaction network. Phytochemicals that inhibit breast cancer were retrieved from the PubChem database and virtual screening was performed using PyRx against the AR protein. Based on Lipinski’s rule and ADMET properties, molecular interaction studies were analyzed using induced fit docking, wherein significant binding interactions were displayed by 2-hydroxynaringenin. Molecular dynamics studies and MM-GBSA of AR and the 2-hydroxynaringenin complex revealed strong and stable interactions. Conclusion AR was identified as a hub protein that is highly expressed in breast cancer and 2-hydroxynaringenin efficacy of counter TNBC needs to be investigated further in vitro and in vivo.

ABSTRACT: Alzheimer's disease (AD) is a polygenic, progressive neurodegenerative condition that leads to cognitive and behavioural impairment. The drugs available for AD have been found vital for symptomatic cognitive treatment, but cannot treat or slow down the disease's progression, besides having severe side effects. Plants have been extensively used in traditional medicine, and marine phytochemicals have also been proven as a legitimate solution for several ailments. This study was carried out to screen marine phytochemicals for AD therapy and neuroinflammation by focusing on inhibiting the neuroinflammatory pathway involved in AD progression and nervous system degeneration using IκK as the therapeutic target protein. Virtual screening of 2583 marine phytochemicals retrieved from the Comprehensive Marine Natural Products Database (CMNPD) was performed for Lipinski's rule, ADME/T profiling, Blood-brain permeability and molecular docking studies using IκK as the target receptor and Curcumin as the standard inhibitor of IκK. Seven marine phytochemicals (CMNPD IDs: CMNPD25050, CMNPD793, CMNPD18964, CMNPD14904, CMNPD31514, CMNPD24296) showed better binding affinity when docked against IκK as compared to the standard compound Curcumin and are the potential lead molecules to be further evaluated for AD therapy. Molecular dynamics simulations were also performed to investigate the binding interactions and stability of the top-hit marine phytochemical CMNPD25050 (8,11-dihydro-1-methoxy laurokamuren-12-ol) with the IκK target protein.

AbstractObjective:Increasing recognition of the potential importance of phytochemicals in the aetiology of cancer and heart diseases has highlighted the need for methods to measure individual phytochemical consumption that are sufficiently simple to be used in large epidemiological studies and whose reproducibility and accuracy have been quantified. D-Limonene is a natural component of a variety of foods and beverages and is found mainly in citrus fruits. However, D-limonene is not assessed by any nationally available analysis database.Design:We designed our study to assess the D-limonene content of different citrus juices and beverages and to develop a dietary assessment instrument to measure consumption of citrus foods (fruit, juice and peel) and D-limonene intake and test it for reliability.Subjects and methods:A total of 120 citrus juice samples were analysed and used to develop the preliminary D-limonene database. A self-administered citrus food-frequency questionnaire was developed and administered twice to participants, separated by a 2-month interval. The questionnaire was tested for reproducibility of estimates of citrus food consumption and D-limonene intake among 120 participants.Results:Correlation coefficients between the two administrations of the questionnaire ranged from 0.50 for citrus peel use to 0.82 for orange juice. Mean intakes (range) of D-limonene from citrus juices among consumers were 13.0 (0.24–141.9) mg day−1 and 13.2 (0.07–83.9) mg day−1 (r = 0.60, P < 0.001).Conclusion:The citrus frequency questionnaire developed in this study provided highly reproducible estimates of citrus foods, citrus peel and D-limonene intakes. This instrument may be a useful tool in studies of the associations between citrus peel use, D-limonene intake and risk for chronic disease.

AbstractWe conducted a systematic review of human trials examining the effects of dietary phytochemicals on Nrf2 activation. In accordance with the PRISMA guidelines, Medline, Embase and CAB abstracts were searched for articles from inception until March 2020. Studies in adult humans that measured Nrf2 activation (gene or protein expression changes) following ingestion of a phytochemical, either alone or in combination were included. The study was pre-registered on the Prospero database (Registration Number: CRD42020176121). Twenty-nine full-texts were retrieved and reviewed for analysis; of these, eighteen were included in the systematic review. Most of the included participants were healthy, obese or type 2 diabetics. Study quality was assessed using the Cochrane Collaboration Risk of Bias Assessment tool. Twelve different compounds were examined in the included studies: curcumin, resveratrol and sulforaphane were the most common (n = 3 each). Approximately half of the studies reported increases in Nrf2 activation (n = 10); however, many were of poor quality and had an unclear or high risk of bias. There is currently limited evidence that phytochemicals activate Nrf2 in humans. Well controlled human intervention trials are needed to corroborate the findings from in vitro and animal studies.

Recently, there has been great interest in plant-derived compounds known as phytochemicals. The pentacyclic oleanane-, ursane-, and lupane-type triterpenes are phytochemicals that exert significant activity against diseases like cancer. Lung cancer is the leading cause of cancer-related death worldwide. Although chemotherapy is the treatment of choice for lung cancer, its effectiveness is hampered by the dose-limiting toxic effects and chemoresistance. Herein, we investigated six pentacyclic triterpenes, oleanolic acid, ursolic acid, asiatic acid, betulinic acid, betulin, and lupeol, on NSCLC A549 cells. These triterpenes have several structural variations that can influence the activation/inactivation of key cellular pathways. From our results, we determined that most of these triterpenes induced apoptosis, S-phase and G2/M-phase cycle arrest, the downregulation of ribonucleotide reductase (RR), reactive oxygen species, and caspase 3 activation. For chemoresistance markers, we found that most triterpenes downregulated the expression of MAPK/PI3K, STAT3, and PDL1. In contrast, UrA and AsA also induced DNA damage and autophagy. Then, we theoretically determined other possible molecular targets of these triterpenes using the online database ChEMBL. The results showed that even slight structural changes in these triterpenes can influence the cellular response. This study opens up promising perspectives for further research on the pharmaceutical role of phytochemical triterpenoids.

The dysregulation of the rat sarcoma (RAS) signaling pathway, particularly the MAPK/ERK cascade, is a hallmark of many cancers, leading to uncontrolled cellular proliferation and resistance to apoptosis-inducing treatments. Dysregulation of the MAPK/ERK pathway is common in various cancers including pancreatic, lung, and colon cancers, making it a critical target for therapeutic intervention. Natural compounds, especially phytochemicals, offer a promising avenue for developing new anticancer therapies due to their potential to interfere with these signaling pathways. This study investigates the potential of anticancer phytochemicals to inhibit the MAPK/ERK pathway through molecular docking and simulation techniques. A total of 26 phytochemicals were screened from an initial set of 340 phytochemicals which were retrieved from Dr. Duke’s database using in silico methods for their binding affinity and stability. Molecular docking was performed to identify key interactions with ERK2, followed by molecular dynamics (MD) simulations to evaluate the stability of these interactions. The study identified several phytochemicals, including luteolin, hispidulin, and isorhamnetin with a binding score of -10.1±0 Kcal/mol, -9.86±0.15 Kcal/mol, -9.76±0.025 Kcal/mol, respectively as promising inhibitors of the ERK2 protein. These compounds demonstrated significant binding affinities and stable interactions with ERK2 in MD simulation studies up to 200ns, particularly at the active site. The radius of gyration analysis confirmed the stability of these phytochemical-protein complexes’ compactness, indicating their potential to inhibit ERK activity. The stability and binding affinity of these compounds suggest that they can effectively inhibit ERK2 activity, potentially leading to more effective and less toxic cancer treatments. The findings underscore the therapeutic promise of these phytochemicals, which could serve as a basis for developing new cancer therapies.

Soybean protein isolate (SPI) and small molecule interactions have drawn more and more attention regarding their benefits for both parts, while research on large-scale investigations and comparisons of different compounds is absent. In this study, a high throughput virtual screening was applied on a phytochemical database with 1130 compounds to pinpoint the potential SPI binder. Pentagalloylglucose, narcissoside, poliumoside, isoginkgetin, and avicurin were selected as the top-five ranking molecules for further validation. Fluorescence quenching assays illustrated that isoginkgetin has a significantly higher apparent binding constant (Ka) of (0.060 ± 0.020) × 106 L·mol−1, followed by avicularin ((0.058 ± 0.010) × 106 L·mol−1), pentagalloylglucose ((0.049 ± 0.010) × 106 L·mol−1), narcissoside ((0.0013 ± 0.0004) × 106 L·mol−1), and poliumoside ((0.0012 ± 0.0006) × 106 L·mol−1). Interface characterization by MD simulation showed that protein residues E172, H173, G202, and V204 are highly involved in hydrogen bonding with the two carbonyl oxygens of isoginketin, which could be the crucial events in SPI binding. Van der Waals force was identified as the major driven force for isoginketin binding. Our study explored SPI–phytochemical interaction through multiple strategies, revealing the molecular binding details of isoginkgetin as a novel SPI binder, which has important implications for the utilization of the SPI–phytochemical complex in food applications.

Hexane, dichloromethane, ethyl acetate, methanol and 50 % aqueous methanol extracts of leaf, flower and fruit of Melastoma malabathricum were screened for the presence of different classes of phytochemicals. In phytochemical screening, ethyl acetate, methanol and 50 % aqueous methanol extracts showed the presence of phenolics and flavonoids. Glycosides were found only in the 50 % methanol extract of fruit. Free radical scavenging activity of methanol extract of leaf, flower and fruit was determined using 2,2-Diphenyl-1-picrylhydrazyl (DPPH) free radical. Total phenolic content was measured spectrophotometrically using Folin-Ciocalteu, total flavonoids content by using aluminum chloride and total sugar content by using anthrone reagent. Gallic acid was used as a standard for the calibration of phenolics, catechin for flavonoids and glucose for carbohydrates. The highest amount of phenolic was found in the 50 % methanol extract of leaf (242.88 ± 3.52 mg GAE/g extract), the highest amount of flavonoids was found in the ethyl acetate extract of leaf (127.41 ± 6.33 mg CE/g extract). Total sugar in 50 % methanol extract of fruit was found to be 151.12 ± 8.79 mg GE/g extract. Methanol extracts of flower showed the strongest antioxidant activity with IC50 value of 17.23 μg/ml. Silyl derivative of hexane extracts were prepared by using N-methyl-N-(trimetylsilyl) trifluoroacetamide for gas chromatography-mass spectroscopic (GC-MS) analysis. The GC-MS analysis of hexane extract allowed the identification of 17 phyto-constituents by comparing the fragmentation pattern of each component in mass spectrum with the standard NIST mass spectral database.

Plants synthesize a large number of natural products, many of which are bioactive and have practical values as well as commercial potential. To explore this vast structural diversity, we present PSC-db, a unique plant metabolite database aimed to categorize the diverse phytochemical space by providing 3D-structural information along with physicochemical and pharmaceutical properties of the most relevant natural products. PSC-db may be utilized, for example, in qualitative estimation of biological activities (Quantitative Structure-Activity Relationship, QSAR) or massive docking campaigns to identify new bioactive compounds, as well as potential binding sites in target proteins. PSC-db has been implemented using the open-source PostgreSQL database platform where all compounds with their complementary and calculated information (classification, redundant names, unique IDs, physicochemical properties, etc.) were hierarchically organized. The source organism for each compound, as well as its biological activities against protein targets, cell lines and different organism were also included. PSC-db is freely available for public use and is hosted at the Universidad de Talca.

Common guava (Psidium guajava) and Pelargonium (Pelargonium zonale) have shown in-vitro antibacterial activity against Ralstonia pseudosolanacearum sp. nov. in previous studies. However, their phytochemical constituents and bioactive compounds against the pathogen have not been identified. The present study investigated the phytochemical components of P. guajava and P. zonale leaf extracts by phytochemical screening and gas chromatography-mass spectrometry (GC-MS). Phytochemical screening was done using different solvents while 100 mg of the dried ethanolic extract pastes from each plant sample was subjected to GC-MS analysis. Automated mass spectral deconvolution and identification system software (AMDIS, US) was used to analyze chromatograms and spectra representing individual compounds. Compound identification was performed by comparing each of the mass spectra with the database of NIST 11 (Gaithersburg, MD, USA), Wiley 7N (John Wiley, NY, USA) and by comparing the calculated Kovats linear retention indices using retention times of n-alkane series against the values in the NIST webbook. Flavonoids, phenols, alkaloids, saponins, terpenoids and tannins were detected in both plant samples. GC-MS analysis revealed presence of 35 and 26 compounds from P. zonale and P. guajava respectively. Both P. zonale and P. guajava had 7 similar compounds with antibacterial properties; Fumaric acid, Phytol, Pyrogallol, 4-Hydroxybenzoic acid, Shikimic acid, Protocatechuic acid and 3, 4, 5-Trihydroxybenzoic acid ethyl ester but P. zonale had one additional antibacterial compound; Lactic acid. In both cases, Shikimic acid had the highest percent peak areas of 3.2% for P. zonale and 6.8% P. guajava respectively. Therefore, P. zonale and P. guajava can serve as alternative sources of active ingredients for formulation of commercial botanicals for the management of bacterial wilt of potato.
