Predicting prospective therapeutic targets of Bombyx batryticatus for managing diabetic kidney disease through network pharmacology analysis.

We conducted network pharmacology and molecular docking analyses, and executed in vitro experiments to assess the mechanisms and prospective targets associated with the bioactive components of Bombyx batryticatus in the treatment of diabetic kidney disease (DKD). The bioactive components and potential targets of B batryticatus were sourced from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform. Using 5 disease databases, we conducted a comprehensive screening of potential disease targets specifically associated with DKD. Common targets shared between the bioactive components and disease targets were identified through the use of the R package, and subsequently, a protein-protein interaction network was established using data from the STRING database. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses pertaining to the identified common targets were conducted using the Database for Annotation, Visualization, and Integrated Discovery. Molecular docking simulations involving the bioactive components and their corresponding targets were modeled through AutoDock Vina and Pymol. Finally, to corroborate and validate these findings, experimental assays at the cellular level were conducted. Six bioactive compounds and 142 associated targets were identified for B batryticatus. Among the 796 disease targets associated with DKD, 56 targets were identified. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analyses revealed the involvement of these shared targets in diverse biological processes and signaling pathways, notably the PI3K-Akt signaling pathway. Molecular docking analyses indicated a favorable binding interaction between quercetin, the principal bioactive compound in B batryticatus, and RAC-alpha serine/threonine-protein kinase. Subsequently, in vitro experiments substantiated the inhibitory effect of quercetin on the phosphorylation level of PI3K and Akt. The present study provides theoretical evidence for a comprehensive exploration of the mechanisms and molecular targets by which B batryticatus imparts protective effects against DKD.

Predicting and Validating the Mechanism of Action of the Enema Formula in Treating Colorectal Cancer by Using Network Pharmacology, GEO, and TCGA Databases

Background: The GCF, created by Professor Liu Shenlin, an esteemed expert in traditional Chinese medicine, is rooted in principles to improve blood flow, relieve blood congestion, clear heat, and detoxify the body. Developed as an empirical formula, it holds significance in CRC treatment. Objective: This study aimed to predict and confirm the active elements, possible targets, and molecular mechanisms against colorectal cancer (CRC) in the GCF enema formula. Methods: Using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), we screened active elements and drug targets. Colorectal cancer (CRC)-related targets were collected from the Online Mendelian Inheritance in Man (OMIM) database, Disease Gene Network (DisGeNET) database, and Therapeutic Target Database (TTD). The overlap between action targets of all active elements and CRC-related targets was determined to find common targets. A Protein-Protein Interaction (PPI) network of common targets was built using the String database, and Cytoscape software was used for visual analysis to identify core targets. Simultaneously, the common targets were analyzed using the Metascape database for Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment. Additionally, core targets and active elements were tested using Discovery Studio 2019 for molecular docking. Furthermore, the expression differences and prognostic impacts of core targets were examined across various cancer databases. Results: Screening revealed 90 active elements and 251 drug targets in the GCF. There were 6113 disease targets, with 113 common targets between CRC and the GCF. Core targets identified through PPI analysis included AKT1, STAT3, MYC, SRC, EGFR, and IL6. KEGG enrichment analysis uncovered 101 relevant pathways related to these targets. Molecular docking experiments confirmed favorable interactions between core targets and multiple active elements in the GCF. Additionally, examination of the Human Protein Atlas (HPA) database highlighted differential expression of core targets MYC and EGFR in normal colorectal tissue compared to CRC tissue. Conclusion: The GCF, comprising a combination of three drugs, appears to counteract CRC by influencing core targets, such as AKT1, STAT3, MYC, SRC, EGFR, and IL6. This process involves regulating multiple cancer-related signaling pathways, notably the PI3K-AKT pathway.

Exploration of the potential mechanism of Yiyi Tongfeng Formula in the treatment of acute gouty arthritis based on network pharmacology and molecular docking: A review.

The global prevalence of gout is on the rise. Yiyi Tongfeng Formula (YTF), a traditional herbal compound, has gained recognition for its efficacy in managing acute gouty arthritis (AGA). Despite its widespread use, the underlying mechanisms of YTF in AGA treatment remain largely undefined. This study employed network pharmacology and molecular docking to elucidate these mechanisms. We utilized the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform, SymMap database, and various literature sources to identify active components and corresponding targets of YTF. Relevant AGA-associated targets were identified through the Genecards, Drugbank, Therapeutic Target Database, and Online Mendelian Inheritance in Man databases. A protein-protein interaction network was constructed to delineate interactions between YTF targets and AGA. Key ingredients and central targets were further analyzed using Cytoscape. Functional enrichment analyses, including Gene Ontology and Kyoto Encyclopedia of Genes and Genomes, were conducted via Metascape. Additionally, molecular docking studies were performed using PyMOL and AutoDock4. It was found that quercetin, kaempferol, and luteolin may be the main active components of YTF for AGA treatment. Gene Ontology enrichment analysis shows that the main biological processes involved are cellular responses to lipids, and inflammatory responses. Kyoto Encyclopedia of Genes and Genomes enrichment analysis suggests the involvement of the IL-17 signaling pathway, AGE-RAGE signaling pathway in diabetic complications, TNF signaling pathway, and so on. The findings suggest a multi-faceted therapeutic approach of YTF in treating AGA, involving multiple components, targets, biological processes, and signaling pathways. This comprehensive mechanism offers a foundation for further experimental validation.

Network pharmacology integrated with molecular docking and molecular dynamics simulations to explore the mechanism of Tongxie Yaofang in the treatment of ulcerative colitis.

Tongxie Yaofang (TXYF), a classical traditional Chinese medicine, is commonly used in China to treat ulcerative colitis (UC). The aim of this study was to integrate network pharmacology with molecular docking and molecular dynamics simulations to explore the mechanism of Tongxie Yaofang in the treatment of UC. The traditional Chinese medicine systems pharmacology database was used to retrieve the relevant chemical compositions of the herbs contained in TXYF. The DisGeNET, GeneCards, Online Mendelian Inheritance in Man, and Therapeutic Target Database databases were used to retrieve UC-related targets. To construct protein-protein interaction networks and screen for key targets, gene ontology and Kyoto Encyclopedia of Genes and Genomes analyses of the key targets of TXYF in the treatment of UC were performed using R 4.3.2 software. AutoDock Tools 1.5.7 was used for molecular docking. Molecular dynamics simulations of protein complexes and complexes of proteins with small-molecule ligands and eutectic ligands were carried out with Gromacs 2022 software. Network pharmacology analysis revealed that TXYF could act on UC through multiple targets and pathways. It may exert therapeutic effects mainly through the AGE/RAGE, TOLL, JAK/STAT, and Th17 signaling pathways. The possible targets of TXYF in the treatment of UC could be AKT1, BCL2, EGFR, HMOX1, HSP90AA1, and TGFβ1. Molecular docking analysis revealed that AKT1 had the highest binding energy (-10.55 kcal/mol). Molecular dynamics simulations revealed that the complexes formed by the AKT1 protein and the chemical compounds MOL001910 and MOL00035 had good stability and high binding strength. AKT1 may be the most critical target of TXYF in treating UC, and the key chemical components of TXYF in treating UC may include β-sitosterol (MOL000358) and 11alpha,12alpha-epoxy-3beta-23-dihydroxy-30-norolean-20-en-28,12beta-olide (MOL00 1910). This study revealed that TXYF may exert therapeutic effects on UC through multiple targets, multiple biological functions, and multiple signaling pathways. This study provides a new insight into the pharmacological mechanism of TXYF in treating UC.

New molecular mechanisms of quercetin in improving recurrent spontaneous abortion based on in-depth network pharmacology and molecular docking.

The increasing prevalence of recurrent spontaneous abortion (RSA) poses significant physical and psychological challenges for affected individuals. Quercetin, a natural plant flavonoid, shows promise in reducing miscarriage rates, yet its precise mechanism remains elusive. This study uses network pharmacology, molecular docking, and experimental validation to explore the molecular pathways through which quercetin mitigates RSA. Quercetin-related target genes were sourced from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), and RSA target genes were retrieved from the Comparative Toxicogenomics Database (CTD), with overlapping targets identified using Venn diagrams. All genes were visualized using the STRING database, and core targets were selected with Cytoscape 3.7.3. Gene ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were conducted using the DAVID and Reactome online resources. Subsequently, HTR-8/SVneo cells were stimulated with lipopolysaccharide (LPS) and treated with varying concentrations of quercetin (1, 5, and 10μM), then subjected to CCK-8, wound healing, transwell, and annexin V-FITC/PI apoptosis assays. Reverse-transcription quantitative PCR was used to determine the mRNA expression levels of IL-1β, TNF-α, and IL-6 in LPS-induced cells post-quercetin intervention, and western blotting was used to measure AKT1, MMP9, and caspase-3 protein levels. A total of 139 quercetin-associated target genes were identified from the TCMSP database, and 98 disease-associated target genes were obtained from the CTD, resulting in 25 shared target genes. Gene ontology enrichment highlighted the involvement of these targets in positive regulation of apoptosis, response to hypoxia, and intrinsic apoptotic signaling pathway in response to DNA damage. KEGG pathway analysis indicated enrichment in pathways related to interleukin-4 and interleukin-13 signaling, cytokine signaling in the immune system, and apoptosis. Molecular docking studies revealed robust binding of quercetin with MMP9, AKT1, IL-1β, TNF, and caspase-3. In vitro experiments demonstrated that quercetin enhanced LPS-induced cell activity, fostering proliferation, migration, and invasion, and reducing apoptosis. Moreover, quercetin reduced IL-1β, TNF-α, and IL-6 mRNA expression, increased AKT1 and MMP9 protein levels, and reduced caspase-3 expression. Quercetin could mitigate the incidence of RSA by modulating inflammatory responses and apoptotic processes, through upregulation of AKT1 and MMP9, and downregulation of caspase-3, IL-1β, TNF-α, and IL-6. Quercetin opens up a new way of thinking about treating RSA.

Scientific exploration and hypotheses concerning the meridian system in traditional Chinese medicine

The meridian theory is an important component of traditional Chinese medicine, playing a crucial role in disease diagnosis, treatment, and health preservation. Serving as the media for the effects of acupuncture, moxibustion, herbal medicine, and acupressure massage, meridians exert undeniable impact on the human body. However, the essence of meridians remains a topic of debate. Recent research has primarily focused on their anatomical structures, leading to numerous hypotheses. Simultaneously, other researchers have approached this subject from an energetic perspective, discovering information interactions within the meridian system. These findings suggest that meridians possess both physical and information dimensions, indicating that a singular approach to their study is insufficient. To bridge this gap, a shift from purely structural research toward an exploration of the information aspects of meridians is necessary. By integrating this information approach with traditional meridian theory, it may be possible to develop a new, modernized meridian theory that is aligned with contemporary concepts, making it more accessible and applicable in clinical settings.

Background Er-Miao-San (EMS) is a classic prescription in Traditional Chinese Medicine (TCM) for the treatment of colorectal cancer (CRC) and has shown promising therapeutic effects in clinical practice. However, the specific components and molecular mechanisms of EMS remain unclear. Purpose The aim of this study was to analyze the effective components and molecular mechanisms of EMS in treating CRC through network pharmacology techniques and experimental validation. Materials and Methods The Traditional Chinese Medicine Systems Pharmacology database was used to screen the main active chemical components and targets of the EMS formula. The compound structures were verified using the PubChem database, which is an organic small-molecule bioactivity database. GeneCards and OMIM databases were utilized to predict target genes related to CRC. The Cytoscape 3.8 software was used to construct a “Drug-Active Ingredient-Target-Disease” intersection network. The STRING database was employed to analyze the core target protein–protein interaction network shared by EMS and CRC. The core targets were further subjected to Gene Ontology enrichment analysis and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis using the R language. Molecular docking between the core targets and the major active chemical components of EMS was performed using AutoDock software. The impact of the core targets on the prognosis of CRC patients was analyzed using the R language. Subsequently, we validated the potential mechanisms predicted by network pharmacology for the inhibition of CRC cell proliferation by the key proteins in the relevant pathways through CCK8 cell proliferation assays and Western blot experiments. Results Molecular docking results showed good docking affinity between the key active components, such as quercetin and baicalein, of EMS and the core targets. Kaplan–Meier survival analysis demonstrated a close correlation between the core targets and the survival prognosis of CRC patients. Cellular experiments showed that EMS significantly inhibited the proliferation of CRC cells and may promote apoptosis and autophagy of CRC cells by suppressing the expression of key proteins in the PI3K/AKT pathway. Conclusion The TCM formula EMS exerts anti-CRC effects through multiple pathways and targets, improving the prognosis and extending the survival period of CRC patients. This study provides preliminary insights into the effective components and molecular mechanisms of EMS in the treatment of CRC, which were preliminarily validated through molecular docking and experimental approaches.

Huangqi-Shanzhuyu (HS), a classic combination of Chinese herbal formulae, has been widely used for the treatment of diabetic nephropathy (DN). However, its pharmacological mechanism of action is still unclear. The active ingredients of HS and their potential targets were identified through the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and the DN-related targets were determined from GeneCards, Online Mendelian Inheritance in Man (OMIM), PharmGkb, and Therapeutic Target Database (TTD). The Cytoscape software was used to construct a herb-disease-target network and screen core genes. STRING was employed to generate a protein-protein interaction (PPI) network. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed to predict the mechanism of action of HS in DN. Animal experiments and molecular docking were used to verify the potential mechanism. In total, 40 active ingredients and 180 effective targets of HS in DN were identified and 1115 DN-related targets were retrieved. From the PPI network, VEGFA, AKT1, IL6, IL1B, TP53, MMP9, PTGS2, CASP3, EGF and EGFR were identified as core genes. The anti-DN mechanism mainly involved multiple signaling pathways such as AGEs-RAGE. Animal experiments and molecular docking analysis confirmed that HS downregulated the expression of IL-1 and IL-6 via kaempferol-mediated inhibition of JNK1 phosphorylation. HS exhibits a therapeutic effect in DN through its multiple ingredients that act on several targets and multiple signaling pathways, including AGEs-RAGE.

An Overview of Pharmaceutical Applications and In vitro Micropropagation Techniques for Rare and Endangered Plant Species

Many rare and endangered plant species possess valuable secondary metabolites with pharmacological applications. These bioactive compounds are often integral to traditional medicine systems, highlighting the cultural significance of these plants. The health benefits of many medicinal species are not fully validated by contemporary scientific research, and some may be facing extinction due to habitat loss, overharvesting or climate change. This situation highlights the urgent need for effective conservation strategies of the species and sustainable cultivation methods. Micropropagation is a valuable technique for producing large numbers of plants from a single explant, significantly aiding in the conservation and commercial cultivation of rare species. Among the various types of explants, shoot tips and nodal segments have been identified as the most effective explants for micropropagation. These explants can be induced to generate multiple shoots in Murashige and Skoog (MS) medium containing Benzyl aminopurine (BAP). Thidiazuron (TDZ), Kinetin (KIN), or 2,4-Dichlorophenoxyacetic acid (2,4-D) are commonly used in MS medium to promote shoot and root development in both direct and indirect organogenesis processes. Rooting of the plantlets was typically achieved using MS medium either supplemented with Indole-3-butyric acid (IBA) or devoid of auxins, depending on the species and the specific requirements for rooting.

Network pharmacology, molecular docking, and molecular dynamics simulations shed light on the mechanism behind Gynostemma pentaphyllum's efficacy against osteosarcoma.

Osteosarcoma (OS) is the most common type of malignant bone tumor, that poses a serious threat to the lives and health of children and adolescents. Traditional Chinese medicines (TCM) have gained attention for treating OS because of their potent anti-cancer effects and fewer side effects. It is commonly understood that Gynostemma pentaphyllum (Thunb.) Makino (GP) exhibits inhibitory effects on most tumors. However, the knowledge of the systematic mechanisms involved is limited. In this study, the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) was searched to screen the effective ingredients and corresponding target genes of GP, and disease target databases were searched to identify relevant targets for OS. Venn analysis was used to visualize overlapping genes, which were further extracted using the protein-protein interaction network. R software was used to conduct gene ontology and Kyoto encyclopedia of genes and genomes pathway enrichment analysis, molecular docking and molecular dynamics simulation further validate the binding efficacy of potential therapeutic targets to compound molecules. In total, 161 and 1981 proteins were identified as target genes of GP and OS, respectively, and 104 overlapping genes were identified. Through analysis of the core subnetwork, 12 hub genes were identified, and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses revealed that the PI3K/Akt signaling pathway was the most significant. Molecular docking and molecular dynamics simulations show that a high affinity between quercetin and these targets, especially with the combination of TNF free energy (Δ Gbind) minimum, MM/PBSA and MM/GBSA is 42.85 kcal/mol, respectively, and 45.29 kcal/mol. The active ingredients Rhamnazin and Quercetin in Gypenoylum play a therapeutic role in OS through several key targets and pathways. This study provides ideas and references for further research on drug development.

Analysis of Phytochemical Constituents, Pharmacological and Ethnobotanical Studies of Selected Folk Medicinal Plant, Curcuma amada Roxb. (Mango Zinger)

Curcuma amada, also known as Mango ginger, is a distinctive spice that shares morphological similarities with ginger but imparts a raw mango flavor. The primary use of Curcuma amada rhizome lies in pickle and culinary preparations. In traditional medicinal systems such as Ayurveda and Unani, Curcuma amada is highly valued for its diverse properties, serving as an appetizer, alexteric, antipyretic, aphrodisiac, diuretic, emollient, expectorant, and laxative. It is prescribed to address various conditions, including biliousness, itching, skin diseases, bronchitis, asthma, hiccough, and inflammation from injuries. Despite its extensive traditional use, there is a scarcity of studies exploring the antioxidant, antimicrobial, and cytotoxic activities of Curcuma amada rhizome extract. Antibacterial activity was assessed using the agar well diffusion method against Gram-positive Staphylococcus aureus and three Gram-negative strains- Klebsiella pneumonia, Escherichia coli, and Acetobacter aceti. The study aims to investigate the antimicrobial and cytotoxicity activities, as well as conduct in silico pharmacological analysis of Curcuma amada. In antibacterial tests, a notable zone of inhibition was observed against Acetobacter aceti and Escherichia coli, while none was observed against Klebsiella pneumoniae and Staphylococcus aureus. Cytotoxicity was assessed through a brine shrimp lethality bioassay, revealing results based on mortality numbers and the percentage of affected brine shrimp. In the in silico analysis, which evaluates pharmacological activity through pharmacokinetic analysis and molecular docking, four phytochemicals (E)-.beta.-Farnesene, eupatin, 3-Carene, and coumarin from the plant were selected. These phytochemicals were docked against the Estrogen receptor alpha (ERα), a protein associated with breast cancer. The docking results demonstrated promising binding scores, with E-.beta.-Farnesene, eupatin, 3-Carene, and coumarin scoring -11.3, -6, -6.3, and -8.1, respectively. J. of Sci. and Tech.

Bioactivity Profiling and Phytochemical Analysis of Carissa carandas Extracts: Antioxidant, Anti-Inflammatory, and Anti-Urinary Tract Infection Properties.

Carissa carandas L. (Apocynaceae) is widely distributed in tropical and subtropical regions of Asia including Pakistan, India, Afghanistan, and Sri Lanka. C. carandas is considered as an integral component of traditional medicinal systems to combat several health ailments. The present study aimed to assess this plant's phytochemical contents and biological potential by performing sequential extraction, adopting a bioassay-guided approach. C. carandas powder was extracted with n-hexane to remove fatty substances and then residues were sequentially extracted with dichloromethane, methanol, and 50% methanol. All the sequential crude extracts were evaluated for phytochemical contents (total phenolics, flavonoids, and anthocyanins), in vitro antioxidant activity (FRAP, DPPH), in vitro anti-inflammatory activity (serum and egg albumin denaturation), in vivo anti-inflammatory activity (carrageenan- and formaldehyde-induced paw edema), and in vitro antimicrobial activity. Active crude extract was then partitioned using the liquid-liquid separation method followed by further separation of the active fraction by RP-HPLC. The active fraction was then subjected to LC-ESI-MS/MS analysis for tentative identification of bioactive metabolites responsible for its bioactive properties, followed by HPLC quantification. The analysis revealed methanol extract to have more phytochemical contents, radical scavenging properties, reduced inflammation in both models (in vitro and in vivo), and antimicrobial properties against urinary tract infection-causing agents as compared to dichloromethane and 50% methanol extracts. The ethyl acetate fraction obtained after liquid-liquid partitioning (LLP) of the active methanol extract exhibited more activity as compared to C. carandas methanol extract. RP-HPLC sub-fractionation yielded seven sub-fractions, but a slight decrease in biological potential was recorded. Therefore, LLP fraction B was subjected to further analysis. LC-ESI-MS/MS analysis led to the tentative identification of phenolic acids (chlorogenic acid, quinic acid), flavonoids (quercetin), and anthocyanins (peonidin-3-arabinoside, delphinidin-3-galactoside, delphinidin-3-rutinoside) in the active LLP ethyl acetate fraction. Chlorogenic acid, ellagic acid, and quinic acid were quantified as 17.6 µg/mg, 5.90 µg/mg, and 3.30 µg/mg, respectively, on a dry weight basis by HPLC. C. carandas may be considered a promising therapeutic plant, and the results of the current study provide more evidence to support the assertions made in ancient medical traditions. These findings highlight its promising applications in health, medicine, cosmetics, preservatives, and as a natural coloring agent.

BackgroundPotentilla fulgens, a highly valued indigenous medicinal herb grown in high altitudes of the Himalayan region with anticancer, hypoglycaemic, antibacterial, anti-inflammatory, and antiulcerogenic properties, are used in traditional systems of medicine. This study was aimed to investigate the effect of P. fulgens root extract, as one of the natural alternatives to chemotherapeutic drugs used in cancer treatment, on proliferation, apoptosis, and autophagy of human non-small cell lung cancer cell line (A549), human ovarian cancer cell line (SKOV-3), and healthy human umbilical vein endothelial cell line (HUVEC). MethodsAnti-proliferative effect was assessed by MTT assay. The expression of autophagy and apoptosis-related proteins was evaluated by western blotting. Total oxidant status (TOS) and total antioxidant capacity (TAC) test were determined using standard kit methods. ResultsOur results showed that the extract inhibited proliferation of HUVEC, A549, and SKOV-3 cells in a dose-dependent manner. MTT assay analysis revealed that the extract significantly (P<0.05) induced mortality in HUVEC, A549, and SKOV-3 cells. Western blot results revealed increased expression of NF-κB after the extract treatment but led to the down-regulation in Beclin-1, Bax, extracellular-signal-related kinase 1 and 2, Sequestosome-1, and cleaved Casp-3 levels. Treatment groups showed an increase in TOS and TAC values in A549 and SKOV-3 cell lines, while HUVEC cell line showed an increase in TAC and a decrease in TOS values, compared to the control group. ConclusionsOur findings indicated that P. fulgens root extract inhibited the proliferation of healthy cells and cancer cells through cell cycle arrest, representing its limited application as therapeutic agent in cancer treatment.

Studies on the Anti-Inflammatory Effect of Xiaoyao Pills in The Treatment of Postmenopausal Osteoporosis in Mice.

Osteoporosis is a common metabolic disease of elderly and postmenopausal women, with no obvious symptoms during its early stages. In the latter stages of this condition, the patients are prone to fractures, and this can seriously affect their health and quality of life. The worldwide increase in life expectancy has made osteoporosis a global concern. The Xiaoyao pills were previously used in the treatment of depression. In addition, the drug appeared to have estrogen-like activity, which affected the expression of ALP, an early osteoblast-specific marker, and COL-1, a major component of bone extracellular matrix. Xiaoyao pills were assessed for their effects on postmenopausal osteoporosis (PMOM) in mice. The target information of each herbal component of Xiaoyao pills was accessed through the Traditional Chinese Medicine Systems Pharmacology (TCMSP) database. Information from GeneCards, OMIM, PharmGkb, TTD, DrugBank, and other websites was used to construct the regulatory network of the herbal complex through Cytoscape and String network to assess the protein interactions. Mice were ovariectomized, and treated with high and low doses of Xiaoyao pills and these were compared to controls. Their symptoms were assessed by immunocytochemistry of bone tissues. The results suggested that Xiaoyao pills had the ability to alleviate the symptoms of PMOM in ovariectomized mice through the IL-17 signaling pathway. This drug has the potential to become a novel therapeutic agent for the treatment of osteoporosis.

Network pharmacology revealed that the main active components of the target of action were kaempferol, beta-sitosterol, ginsenoside rh2, stigmasterol, and fumarine. Core targets of the protein-protein interaction network included TNF, IL-1β, AKT1, PTGS2, BCL2, and JUN. Kyoto Encyclopedia of Genes and Genomes enrichment analysis showed that they were mainly involved in AGE-RAGE signaling pathway in diabetic complications, TNF signaling pathway, Lipid and atherosclerosis. The interactions of core active components and targets were analyzed by molecular docking. Ginseng may play a comprehensive therapeutic role in the treatment of DM-induced ED and asthenospermia through "multicomponent, multi-target, and multi-pathway" biological mechanisms such as inflammation and oxidative stress.
