In vivo anthelmintic effect of Artemisia annua L. on oxyurid nematodes of laboratory mice

Oxyurids are common intestinal parasites of mammals, and they are the cause of recurrent helminthic infections, especially in children Hence natural herbal compounds are necessary for a repeatable cure. This study aimed to investigate the antinematodal effect of Artemisia annua L. n-hexane extract on oxyurids in vivo. In this study, A. annua L. n-hexane extract was applied to mice naturally infected with Syphacia obvelata and Aspiculuris tetraptera species orally at 300, 600, and 1200 mg/kg doses for seven days and the change occurring in the number of oxyurid eggs was investigated by the fecal flotation method. The nematodes in the necropsy were compared on the 8th day in all groups in terms of number, gender, and species. Albendazole (ABZ) was applied at a 5 mg/kg dose for three days as positive drug control, and corn oil was used as solvent control. The arithmetic mean of oxyurid eggs counted in fecal flotation 43.51% decrease in the drug control ABZ group and showed a 21.12% increase in the A. annua 1200 mg/kg group on the last day of application. When compared with the corn oil group, a 34.08%, 34.76% and 36.91% decrease in ABZ 5 mg/kg, A. annua 300 mg/kg and A. annua 1200 mg/kg group respectively were found in their necropsies in terms of nematode number. Non-polar compounds of A. annua L., very low concentration of ABZ and as a dilution solvent corn oil are probably responsible for this result.

Targeting SARS-CoV-2 Spike and Main protease with phytochemicals from Herbs and spices: Molecular Docking and dynamics simulation studies.

Abstract COVID-19, a pandemic disease has affected 480 million people and caused 6 million deaths around the world. Despite the progress made in COVID-19 drug discovery, SARS-CoV-2, the causative agent of this disease continuously mutates and rapidly evolves into new variants. This increases the challenges in drug discovery for COVID-19. As natural products serve as sources of drugs forever, this study applies computational techniques in predicting the natural compounds in herbs and spices of household origin as SARS-CoV-2 spike and protease inhibitors and also verifies the top hits against spike and protease mutants associated with SARS-CoV-2 variants of concern. This study reveals Hesperidin, Diosgenin, Fenugreekine, Epigallocatechin gallate and Quercetin as SARS-CoV-2 spike and protease inhibitors, which acts better than the drug Remdesivir. The efficiency of the top hits was also been verified against the mutants, which reveals Diosgenin and Fenugreekine as the most efficient natural compounds against SARS-CoV-2 spike mutants (N501Y, E484K, K417N and K417T), which are associated with SARS-CoV-2 variants of concern. Additionally, Hesperidin is proven to have better binding efficiency against Mpro mutants (Y54C, A191V, T190I and N142S). Overall, this study concludes that Hesperidin, Diosgenin and Fenugreekine could combat both SARS-CoV-2 and its variants effectively.

S1P Signaling Genes as Prominent Drivers of BCR-ABL1-Independent Imatinib Resistance and Six Herbal Compounds as Potential Drugs for Chronic Myeloid Leukemia.

Imatinib (IM), a breakthrough in chronic myeloid leukemia (CML) treatment, is accompanied by discontinuation challenges owing to drug intolerance. Although BCR-ABL1 mutation is a key cause of CML resistance, understanding mechanisms independent of BCR-ABL1 is also important. This study investigated the sphingosine-1-phosphate (S1P) signaling-associated genes (SphK1 and S1PRs) and their role in BCR-ABL1-independent resistant CML, an area currently lacking investigation. Through comprehensive transcriptomic analysis of IM-sensitive and IM-resistant CML groups, we identified the differentially expressed genes and found a notable upregulation of SphK1, S1PR2, and S1PR5 in IM-resistant CML. Functional annotation revealed their roles in critical cellular processes such as proliferation and GPCR activity. Their network analysis uncovered significant clusters, emphasizing the interconnectedness of the S1P signaling genes. Further, we identified interactors such as BIRC3, TRAF6, and SRC genes, with potential implications for IM resistance. Additionally, receiver operator characteristic curve analysis suggested these genes' potential as biomarkers for predicting IM resistance. Network pharmacology analysis identified six herbal compounds-ampelopsin, ellagic acid, colchicine, epigallocatechin-3-gallate, cucurbitacin B, and evodin-as potential drug candidates targeting the S1P signaling genes. In summary, this study contributes to efforts to better understand the molecular mechanisms underlying BCR-ABL1-independent CML resistance. Moreover, the S1P signaling genes are promising therapeutic targets and plausible new innovation avenues to combat IM resistance in cancer clinical care in the future.

Potential target and mechanism exploration from α-mangostin against triple-negative breast cancer: An in silico study.

Triple-negative breast cancer (TNBC) is one of the most common types of serious breast cancer. Due to the absence of therapeutic hormone receptors, TNBC treatment generally involves chemotherapy which results in various side effects and resistance development. Herbal compounds, including α-mangostin, have shown potential anticancer effects against TNBC. However, rigorous screening is needed to uncover its mechanisms and characteristics. The aim of this study was to understand the molecular mechanism of α-mangostin against TNBC and its possible limitations. The study design used is an in si lico study. The study involved database mining and compound characteristic analysis. Network pharmacology and molecular docking were also done to explore potential target and molecular mechanisms against TNBC. There was no statistical analysis conducted as this study relies on predefined algorithms and simulation models. Instead, a parameter threshold was used for each analysis to ensure its reliability. Prediction of Activity Spectra for Substances prediction and Gene Ontology-Kyoto Encyclopedia of Genes and Genomes enrichment predicted potential anticancer effects of α-mangostin through the regulation of enzyme activity and apoptotic pathway. Compound property predictions showed α-mangostin to have promising drug-likeness with sufficient bioavailability and low biodegradability. However, α-mangostin still has some potential limitations in water solubility and toxicity risks. Through network pharmacology, 75 potential target proteins of α-mangostin in TNBC cases were found. The top three most significant of which (AKT1, CTNNB1, and HSPAA91) were proven to bind with α-mangostin through molecular docking. Study results suggested α-mangostin to have a promising anticancer and chemopreventive activity with great drug-likeness and pharmacokinetic properties. It was revealed that α-mangostin can bind to key components in TNBC-related pathways, including AKT1, CTNNB1, and HSP90AA1 proteins. However, further experimental studies may be needed to verify its effectiveness as well as possible solubility and toxicity limitations.

Phylogenetic and spatial patterns of herbal medicine compounds: Which medicinal plants are phytochemically characterized?

ObjectiveThe study of phytometabolites of medicinal plants and their phylogenetic distribution is an important content of pharmacophylogeny. The objectives of this study were to provide an updated estimate of the extent to which the medicinal plants were investigated phytochemically and relate this to the species-level phylogeny and their geographical pattern. MethodsHere, we further characterized 1648 phytometabolites, including terpenoids, steroids, flavonoids, phenylpropanoids, phenolics, alkaloids, etc., reported in journals Chinese Traditional and Herbal Drugs (Zhong Cao Yao) and Chinese Herbal Medicines (CHMs) from the phylogenetic and spatial perspectives. According to the structural characteristics, terpenoids, flavonoids, alkaloids and phenylpropanoids were subdivided into subclasses, and the research effort of phytometabolites was for the first time delineated at both subclass and phylogenetic levels. ResultsThe phytometabolites of 90 families were reported on two journals in three years. It is noted that terpenoids with diverse bioactivities still constitute the primary object of phytochemical research, followed by flavonoids, phenolics, phenylpropanoids and alkaloids. Among the reported species, the family Asteraceae had the most, followed by Lamiaceae, Fabaceae, and Ranunculaceae. In the phylogenetic distribution of the reported phytometabolites, the NRI (net relatedness index) results revealed a clustered structure for triterpene, iridoid, flavone, flavonol, coumarin, indole alkaloid and terpenoid alkaloid, while the NTI (nearest taxon index) metric identified the clustered structure for triterpene, sesquiterpene, indole alkaloid and terpenoid alkaloid. Especially in Ranunculaceae, there were more reports on triterpene and terpenoid alkaloid subclasses. The overdispersion pattern of diterpene and phenolic was suggested by NRI and NTI respectively, albeit more reported diterpenes and phenolics were in Lamiaceae. The geographical distribution hotspots of reported species and compounds thereof highlighted the enormous progress of herbal medicine research and industry, which play a positive role in the future drug discovery and development. ConclusionThese results provide new dimensions and perspectives in the context of pharmacophylogeny for perceiving and evaluating research trends and flashpoints in medicinal phytochemistry.

Optimizing Wall Material Ratios for Enhanced Bioactive Compound in Ficus deltoidea using Freeze Drying

Ficus deltoidea (FD) is well documented for its pharmacological properties, including anticancer, antibacterial, anti-inflammatory, antiviral and anti-aging properties. However, the stability and adsorption of many bioactive compounds in herbs are poor, limiting their bioavailability. This study aimed to investigate the optimal formulation ratios and different wall materials (maltodextrin (MD) and gum Arabic (GA)) for encapsulating FD extract using freeze drying. Physicochemical characterizations of the formulated FD powders included evaluation of marker compound (isovitexin), phenolics (TPC) and flavonoids (TFC) content. The safety of the optimized encapsulated FD (OEFD) powder was assessed through microbiological assay. The optimal conditions, determined through response surface methodology (RSM), were a solid ratio of 20% w/v, a 75% MD: 25%GA and 3:1 of core to wall ratio, which resulted in the highest retention of isovitexin at 1.96 g/g, phenolic content of 1473 GAE mg/ 10 g extract and flavonoids content of 185 CE mg/ 10 g extract. Optimizing the freeze -drying process for FD extract improved its quality by retaining the marker compound. This optimization ensures that the bioactive compounds remain stable and effective, enhancing the therapeutic potential of the extract.

APPLICATION OF MODERN METHODS OF ANALYSIS FOR DETERMINATION OF POLLUTION AND IDENTIFICATION OF PLANT RAW MATERIALS

Quality control of herbal preparations is an important component to ensure the effectiveness and safety of their use. Phytochemical medicines are made from medicinal plant materials that may contain unwanted chemical compounds, so careful quality control must be performed to ensure their safety and efficacy. The success of quality control of herbal materials requires an integrated approach, i.e. a combination of various techniques and methods that allow analyzing the main classes of compounds. Various methods of analysis are used to overcome these difficulties. Today, the main chemical methods for determining the quality of medicinal products are chromatographic, in particular gas chromatography (GC), often combined with mass spectrometry (MS), liquid chromatography (HPLC), thin-layer chromatography (TLC), column chromatography (CC). Besides, HILIC is the optimal method for the analysis of polar and ionized compounds that are too strongly retained on polar stationary phases and/or poorly separated by standard chromatographic methods. TLC/HPTLC methods are traditionally used by the SPhU and the European Pharmacopoeia for identification of herbs and detection of impurities by visual assessment, as well as for semi-quantitative determination of compounds when comparing the intensity of the spot in the zone of the tested solution with spots in the zones of reference compounds. The mentioned methods have still remained the most acceptable for the identification of herbs, which is explained by the unique chromatographic profile of each plant or extract based on it. At the same time, the instrumental method of HPLC has advantages due to the possibility of quantitative determination of substances that fluoresce in UV or visible light. Nowadays, the direction of scientific research devoted to the optimization of the previously described analytical methods and the development of new ones for the identification of both herbs and herbal materials, as well as herbal remedies, becomes relevant. In addition, the development of methods for the quantitative determination of herbal compounds is a relevant scientific and practical direction.

Exploring molecular targets: herbal isolates in cervical cancer therapy

ObjectiveCervical cancer (CxCa) stands as a significant global health challenge, ranking fourth in cancer-related mortality among the female population. While chemotherapy regimens have demonstrated incremental progress in extending overall survival, the outlook for recurrent CxCa patients remains disheartening. An imperative necessity arises to delve into innovative therapeutic avenues, with molecular targeted therapy emerging as a promising candidate. Previous investigations have shed light on the therapeutic effectiveness of five distinct herbal compounds, epicatechin, curcumin, myricetin, jatrorrhizine, and arborinine, within the context of CxCa.MethodsA systems biology approach was employed to discern differentially expressed genes (DEGs) in CxCa tissues relative to healthy cervical epithelial tissues. A protein–protein interaction network (PPIN) was constructed, anchored in the genes related to CxCa. The central genes were discerned within the PPIN, and Kaplan–Meier survival curves explored their prognostic significance. An assessment of the binding affinity of the selected herbal compounds to the master regulator of prognostic markers in CxCa was conducted.ResultsA significant correlation between the overexpression of MYC, IL6, JUN, RRM2, and VEGFA and an adverse prognosis in CxCa was indicated. The regulation of these markers is notably influenced by the transcription factor CEBPD. Molecular docking analysis indicated that the binding affinity between myricetin and the CEBPD DNA binding site was robust.ConclusionThe findings presented herein have unveiled pivotal genes and pathways that play a central role in the malignant transformation of CxCa. CEBPD has emerged as a potential target for harnessing the therapeutic potential of myricetin in this context.

An Innovative HPTLC-based Approach for the Quantification of Withaferin A in Combinations of Herbal Compounds

Withaferin A in herbal mixed dose forms was quantified utilizing a new destructive reagent that is quick, accurate, and economical. Toluene, ethyl acetate, and formic acid were mixed in a mobile phase with a ratio of 5:4:2 v/v/v, and separation was carried out at a detection wavelength of 254 nm. In accordance with ICH guidelines, the procedure was verified. A range of 90 to 630 ng/band was determined for the calibration. The method was validated in three separate experiments with varying concentrations of the standard additive. The limit of detection (LoD) of 2.43 ng and the limit of quantitation (LoQ) of 7.54 ng were noted. During system adaptability testing, %RSD was under 2. Using the same approach, unchanged, on nine different formulations proved the method’s separation and quantification efficiency

Rapid discovery of natural skin-lightening ingredients based on an integrated screening strategy based on molecular docking and zebrafish model.

Natural herbs have been widely considered a reservoir for skin-lightening ingredients, but discovery of the effective ingredients from herbs remains a large challenge. This research aimed to rapidly identify compounds with skin-lightening activity in Chinese herbs. The structure information of herbal compounds was collected and selected from the open-source data. High throughput virtual screening (HTVS) and Extra precision (XP) docking modes were used to screen for compounds that could bind to the mushroom tyrosinase involved in melanin synthesis. Furthermore, molecular dynamics (MD) simulations were introduced to assess the binding stability of those compounds with the key target protein. The candidate compounds found by this kind of multidimensional molecular screening were finally tested for their ability to inhibit pigmentation and potential toxicity using an invivo zebrafish animal model. A Natural Compounds Database was established with 5616 natural compounds. Fourteen compounds with favorable binding capability were screened by the XP docking mode with mushroom tyrosinase and five compounds among them were found to have superior dynamic binding performance through MD simulations. Then the Zebrafish animal experiments revealed that two components, sennoside B (SB) and sennoside C (SC), could significantly inhibit melanogenesis rather than the other three compounds. Meanwhile, there were no obvious side effects observed in SB and SC about the morphology, heart rate, or body length of zebrafish. A strategy for rapid screening of compounds with whitening activity has been established, and two potent skin-lightening compounds, SB and SC, have been identified from a vast library of herbal compounds. This study revealed that SB and SC have potential for topical use in skin lightening for the first time. The findings of this study would provide an important theoretical basis for the application of these two compounds in the cosmetic field in the future.

The effectiveness of antioxidant agents in delaying progression of diabetic nephropathy: A systematic review of randomized controlled trials

Introduction: Oxidative stress plays a central role in the pathophysiology of diabetes mellitus and its complications, including diabetic nephropathy. Excessive production of reactive oxygen species (ROS) alters renal metabolic pathways, leading to inflammation, endothelial dysfunction, and fibrosis, ultimately resulting in end-stage renal disease (ESRD). Studies have shown that exogenous antioxidants can improve the pathophysiological condition of patients with diabetic nephropathy. Objective: This systematic review aims to investigate the types of antioxidant agents that inhibit the development of diabetic nephropathy and the effectiveness of antioxidant agent interventions to repair kidney structure and function. Methods: A systematic review of randomized controlled trials that examined the role of antioxidants in improving diabetic nephropathy was conducted. The literature search was performed on PubMed, ScienceDirect, and EBSCO. The inclusion criteria covered articles on the antioxidant activity of herbal extracts and compounds that inhibit the progression of diabetic nephropathy in humans. In addition, the articles were written in English and published between 2012 and 2022. The reporting of the systematic review followed the Preferred Reporting Elements for Systematic Review and Meta-Analysis (PRISMA) guideline. The full texts of all potentially relevant systematic reviews were assessed for quality using the Risk of Bias 2 (RoB 2) tool. Results: A total of 2,367 articles were identified in the three databases, of which only 15 articles met the inclusion criteria. Antioxidant agents that inhibit diabetic nephropathy can be classified as single antioxidants (silymarin, baicalin, epigallocatechin gallate, vitamin E, selenium, curcumin, α-lipoic acid, and tocotrienol-rich vitamin E) and combined antioxidants (α-lipoic acid with vitamin B6, and resveratrol with losartan). Antioxidant agents have been shown to reduce oxidative stress and inflammation, but their role in the progression of fibrosis remains unclear. The oxidative stress marker MDA was significantly reduced by silymarin, curcumin, vitamin E, tocotrienol-rich vitamin E, selenium, ALA, vitamin B, resveratrol and losartan. Silymarin was found to be the most effective (-3.43 µmol/L; 6.02 to 0.83). Compared to silymarin and epigallocatechin gallate, vitamin E was more effective (at -35.4 ng/L; P < 0.001) in reducing inflammation by decreasing TNF-α levels. In addition, tocotrienol-rich vitamin E, silymarin, baicalin, and selenium showed a decrease TGF-β levels, but did not show statistically significant differences between the placebo and intervention groups. Conclusion: Potential antioxidant agents, such as flavonoids, vitamins, fatty acids, and antioxidant minerals, were examined in this systematic review. These agents contribute to reducing markers of oxidative stress and hyperglycemia-induced inflammation. Although several antioxidants play a role in reducing fibrosis markers, the effect does not appear to be statistically significant.

Bioactive Aqueous Fraction of Edible Trigonella foenum‐graecum, Piper betel, and Lagenaria siceraria Homogenate Downregulate the Inflammatory Mediators: In‐silico and In‐vitro Appraisal

AbstractTraditional nutraceutical therapy is a promising approach in the management of inflammatory disorders. Fenugreek, bottle gourd, and betel leaf are rich sources of polyphenolic secondary metabolites. They are abundantly found in the Indian subcontinent for the preparation of healthy traditional functional food. Traditional evidence recommended that these herbs could control inflammation. The study was conducted with those herbs to validate their protective role against inflammatory mediators of arthritis and asthma through in‐silico and in‐vitro models. Phytochemical tests revealed the presence of flavonoids, amino acids, polyphenols, and saponins. Molecular docking was performed against six potential inflammatory bio‐marker proteins, like, LOX‐5, 15‐LOX, PLA2, IL‐6, TNFR1 & TNF‐α with the phyto‐marker compounds of test herbs and found satisfactory binding scores against inflammatory bio‐markers. Extended studies with Fenugreek and betel leaf aqueous fractions showcased 87 % and 91 % inhibition of protein denaturation at 200 μg/ml. Bottle‐gourd and betel‐leaf demonstrated 96 % and 98 % inhibition against 15‐Lipoxygenase at 100 μg/ml. TNF‐α and IL‐6 were dropped significantly by 49 % and 36 % upon treatment of betel leaf at 200 μg/ml from the LPS‐stimulated PBMC cultured cells. Findings may recommend the development of commercial anti‐inflammatory polyherbal phytopharmaceuticals for controlling polyarthritis and inflammatory complications subject to preclinical in‐vivo and clinical investigation.

Application of network pharmacology in synergistic action of Chinese herbal compounds.

Herbal medicines are frequently blended in the form of multi-drug combinations primarily based on the precept of medicinal compatibility, to achieve the purpose of treating diseases. However, due to the lack of appropriate techniques and the multi-component and multi-target nature of Chinese medicine compounding, it is tough to explain how the drugs interact with each other. As a rising discipline, cyber pharmacology has formed a new approach characterized by using holistic and systematic "network targets" via the cross-fertilization of computer technology, bioinformatics, and different multidisciplinary disciplines. It can broadly screen the active ingredients of traditional Chinese medicine, enhance the effective utilization of drugs, and elucidate the mechanism of drug action. We will overview the principles of Chinese medicine compounding and dispensing, the research methods of network pharmacology, and the software of network pharmacology in the lookup of compounded Chinese medicines, aiming to supply thoughts for the better application of network pharmacology in the research of Chinese medicines.

Impact of herbal treatments for Vitiligo disease

Vitiligo is a common skin disorder resulting from the breakdown of functional epidermal melanocytes. The global prevalence of vitiligo ranges from 0.5% to 2%, with higher rates reported in certain populations. Melanocytes, responsible for skin color, are destroyed in vitiligo condition leading to the appearance of smooth, white patches on the skin. The progression of vitiligo is influenced by various factors, including genetics, autoimmunity, psychosis, melanocyte self-destruction, trace element deficiency, oxidative stress, and other biochemical and environmental variables. Recent research has identified herbal plant extractions as potential agents for re-pigmentation and regeneration of normal skin color. Specific components of these herbal plants, such as furocoumarin, thymoquinone, flavonoids, curcuminoids, and glycyrrhizin, play crucial roles in promoting re-pigmentation. Combination therapies involving these herbal compounds have shown promise in increasing tyrosinase activity and reducing oxidative stress, which are two important aspects of vitiligo treatment. The review aims to comprehensively evaluate the efficacy of herbal plant therapies for melanocyte re-pigmentation in vitiligo patients. By analyzing the effectiveness of various herbal extracts and their active components, this study seeks to advance the understanding and potential application of herbal treatments for vitiligo. The findings from this review may contribute to the current knowledge on therapeutic options available for vitiligo patients.

In Silico Prediction of Potential Inhibitors for Targeting RNA CAG Repeats via Molecular Docking and Dynamics Simulation: A Drug Discovery Approach.

Spinocerebellar ataxia (SCA) is a rare neurological illness inherited dominantly that causes severe impairment and premature mortality. While each rare disease may affect individuals infrequently, collectively they pose a significant healthcare challenge. It is mainly carried out due to the expansion of RNA triplet (CAG) repeats, although missense or point mutations can also be induced. Unfortunately, there is no cure; only symptomatic treatments are available. To date, SCA has about 48 subtypes, the most common of these being SCA 1, 2, 3, 6, 7, 12, and 17 having CAG repeats. Using molecular docking and molecular dynamics (MD) simulation, this study seeks to investigate effective natural herbal neuroprotective compounds against CAG repeats, which are therapeutically significant in treating SCA. Initially, virtual screening followed by molecular docking was used to estimate the binding affinity of neuroprotective natural compounds toward CAG repeats. The compound with the highest binding affinity, somniferine, was then chosen for MD simulation. The structural stability, interaction mechanism, and conformational dynamics of CAG repeats and somniferine were investigated via MD simulation. The MD study revealed that during the simulation period, the interaction between CAG repeats and somniferine stabilizes and results in fewer conformational variations. This in silico study suggests that Somniferine can be used as a therapeutic medication against RNA CAG repeats in SCA.

Bioinformatics and Gene Expression Omnibus Analysis of Key Candidate Genes and Pathways Associated with Femoral Head Necrosis

Background: Femoral head necrosis (FHN) is a debilitating bone disease affecting an estimated 8 million people worldwide. Although specific drugs for FHN have limitations, targeted therapies have shown promising results. The significance of this study is underscored by the high prevalence of FHN, the limitations of current treatments, and the potential of targeted drugs and natural compounds for effective therapeutic interventions. Objectives: This study aimed to explore the genetic landscape and associated pathways of FHN through bioinformatics analysis of Gene Expression Omnibus (GEO) data and molecular docking simulations targeting specific enzymes implicated in FHN. Methods: Differentially expressed genes (DEGs) in FHN samples were identified from GEO datasets, specifically accession number GSE123568 (Platform: GPL15207). Functional enrichment analysis was performed using the Database for Annotation, Visualization, and Integrated Discovery (DAVID) to identify enriched pathways and Gene Ontology (GO) terms. Additionally, a protein-protein interaction (PPI) network was constructed using the STITCH (search tool for interaction of chemicals) database, which helped identify top hub genes and proteins. Molecular docking was conducted against key proteins using compounds from the topical chinese herbal medicine (TCHM) database associated with FHN. Results: The study provided a comprehensive bioinformatics analysis of key candidate genes and pathways associated with FHN, which may serve as potential therapeutic targets. It was found that FHN is associated with mitogen-activated protein kinases (MAP4K4/ MAPK8/ MAPK9) and interleukins (IL1b/ IL19/ IL26). Molecular docking results showed strong interactions of traditional Chinese herbal compounds through hydrogen bonding and electrostatic interactions at the active sites of the top ten target proteins associated with FHN. Conclusions: The study confirmed that FHN is linked with enzymes such as mitogen-activated protein kinases (MAPKs), interleukins, tumor necrosis factors (TNFs), and VEGFA (vascular endothelial growth factor A). Molecular docking simulations demonstrated that hesperidin, naringin, and curcumin exhibit potent inhibition against key proteins involved in FHN. Future research will focus on elucidating the specific roles of genes associated with FHN and exploring potential therapeutic targets using natural compounds.

An Investigation into the Effects of Chemical, Pharmaceutical, and Herbal Compounds on Neuroglobin: A Literature Review.

Neuroglobin (Ngb) is an oxygen-binding globin protein that is mainly expressed in the neurons of the central and peripheral nervous system. However, moderate levels of Ngb have also been detected in non-neural tissues. Ngb and Ngb modulating factors have been increasingly studied over the last decade due to their neuroprotective role in neurological disorders and hypoxia. Studies have shown that a number of chemicals, pharmaceuticals, and herbal compounds can modulate the expression of Ngb at different dose levels, indicating a protective role against neurodegenerative diseases. Iron chelators, hormones, antidiabetic drugs, anticoagulants, antidepressants, plant derivatives and short-chain fatty acids are among these compounds. Therefore, this study aimed to review the literature focused on the possible effects and mechanisms of chemical, pharmaceutical, and herbal compounds on Ngbs.

Aromatic Plants as Potential Resources to Combat Osteoarthritis.

Osteoarthritis, which affects an estimated 10% of men and 18% of women over the age of 60 and is increasing in genetic prevalence and incidence, is acknowledged as the condition that degrades the quality of life for older adults in the world. There is currently no known treatment for osteoarthritis. The majority of therapeutic methods slow the progression of arthritis or treat its symptoms, making effective treatment to end the degenerative process of arthritis elusive. When non-pharmacological therapy is ineffective, various pharmacological therapies may be used to treat osteoarthritis. Pharmacological therapy, however, can have major adverse effects and be very expensive. As a result, alternative remedies have been researched. The promise for the safe and efficient management of osteoarthritis has been demonstrated by herbal remedies. Experimental research suggests that herbal extracts and compounds can reduce inflammation, inhibit catabolic processes, and promote anabolic processes that are important for treating osteoarthritis. Due to their therapeutic and innate pharmacological qualities, aromatic herbs are frequently employed as herbal remedies. Recent research has shown that aromatic plants have the potency to treat osteoarthritis. Additionally, complex mixtures of essential oils and their bioactive ingredients, which have anti-inflammatory and antioxidant properties and are obtained from aromatic plants, are frequently utilized as complementary therapies for osteoarthritis. To establish new study avenues, the advantageous anti-osteoarthritic effects of aromatic herbal medicines, including plants, essential oils, and their bioactive components, are extensively discussed.

Targeting ferroptosis using Chinese herbal compounds to treat respiratory diseases

BackgroundRespiratory diseases pose a grave threat to human life. Therefore, understanding their pathogenesis and therapeutic strategy is important. Ferroptosis is a novel type of iron-dependent programmed cell death, distinct from apoptosis, necroptosis, and autophagy, characterised by iron, reactive oxygen species, and lipid peroxide accumulation, as well as glutathione (GSH) depletion and GSH peroxidase 4 (GPX4) inactivation. A close association between ferroptosis and the onset and progression of respiratory diseases, including chronic obstructive pulmonary disease, acute lung injury, bronchial asthma, pulmonary fibrosis, and lung cancer, has been reported. Recent studies have shown that traditional Chinese medicine (TCM) compounds exhibit unique advantages in the treatment of respiratory diseases owing to their natural properties and potential efficacy. These compounds can effectively regulate ferroptosis by modulating several key signalling pathways such as system Xc− -GSH-GPX4, NCOA4-mediated ferritinophagy, Nrf2-GPX4, and Nrf2/HO-1, thus playing a positive role in improving respiratory diseases. PurposeThis comprehensive review systematically outlines the regulatory role of ferroptosis in the onset and progression of respiratory diseases and provides evidence for treating respiratory diseases by targeting ferroptosis with TCM compounds. These insights aim to offer potential remedies for the clinical prevention and treatment of respiratory diseases. Study design and methodsWe searched scientific databases PubMed, Web of Science, Scopus, and CNKI using keywords such as “ferroptosis”,“respiratory diseases”,“chronic obstructive pulmonary disease”,“bronchial asthma”,“acute lung injury”,“pulmonary fibrosis”,“lung cancer”,“traditional Chinese medicine”,“traditional Chinese medicine compound”,“monomer”, and “natural product” to retrieve studies on the therapeutic potential of TCM compounds in ameliorating respiratory diseases by targeting ferroptosis. The retrieved data followed PRISMA criteria (preferred reporting items for systematic review). ResultsTCM compounds possess unique advantages in treating respiratory diseases, stemming from their natural origins and proven clinical effectiveness. TCM compounds can exert therapeutic effects on respiratory diseases by regulating ferroptosis, which mainly involves modulation of pathways such as system Xc− -GSH-GPX4,NCOA4-mediated ferritinophagy, Nrf2-GPX4, and Nrf2/HO-1. ConclusionTCM compounds have demonstrated promising potential in improving respiratory diseases through the regulation of ferroptosis. The identification of specific TCM-related inducers and inhibitors of ferroptosis holds great significance in developing more effective strategies. However, current research remains confined to animal and cellular studies, emphasizing the imperative for further verifications through high-quality clinical data.
