Research progress on evodiamine, a bioactive alkaloid of Evodiae fructus: Focus on its anti-cancer activity and bioavailability (Review)

Immobilized cells on microcarriers for efficient and biomimetic screening of active compounds acting on FGFR4 from Fructus evodiae

Cell membrane coating strategies have been increasingly researched in new drug discovery from complex herb extracts. However, these systems failed to maintain the functionality of the coated cells because cell membranes, not whole cells were used. Original source cells can be used as a vector for active compound screening in a manner that mimics in vivo processes. In this study, we established a novel approach to fabricate high-density fibroblast growth factor receptor 4 (FGFR4)-HEK293 cells on microcarriers covered with collagen through cell culture and covalent immobilization between proteins. This method enables the efficient screening of active compounds from herbs. Two compounds, evodiamine and limonin, were obtained from Fructus evodiae, which were proven to inhibit the FGFR4 target. Enhanced immobilization effects and negligible damage to FGFR4-HEK293 cells treated with paraformaldehyde were successfully confirmed by immunofluorescence assays and transmission electron microscopy. A column was prepared and used to analyze different compounds. The results showed that the method was selective, specific, and reproducible. Overall, the high density of cells immobilized on microcarriers achieved through cell culture and covalent immobilization represents a promising strategy for affinity screening. This approach highlights the potential of the affinity screening method to identify active compounds from an herbal matrix against designed targets and its prospects for use in drug discovery from herbs.

Maintaining calcium homeostasis as a strategy to alleviate nephrotoxicity caused by evodiamine

Evodiamine (EVO), the main active alkaloid in Evodia rutaecarpa, was shown to exert various pharmacological activities, especially anti-tumor. Currently, it is considered a potential anti-cancer drug due to its excellent anti-tumor activity, which unfortunately has adverse reactions, such as the risk of liver and kidney injury, when Evodia rutaecarpa containing EVO is used clinically. In the present study, we aim to clarify the potential toxic target organs and toxicity mechanism of EVO, an active monomer in Evodia rutaecarpa, and to develop mitigation strategies for its toxicity mechanism. Transcriptome analysis and related experiments showed that the PI3K/Akt pathway induced by calcium overload was an important step in EVO-induced apoptosis of renal cells. Specifically, intracellular calcium ions were increased, and mitochondrial calcium ions were decreased. In addition, EVO-induced calcium overload was associated with TRPV1 receptor activation. In vivo TRPV1 antagonist and calcium chelator effects were observed to significantly reduce body weight loss and renal damage in mice due to EVO toxicity. The potential nephrotoxicity of EVO was further confirmed by an in vivo test. In conclusion, TRPV1-mediated calcium overload-induced apoptosis is one of the mechanisms contributing to the nephrotoxicity of EVO due to its toxicity, whereas maintaining body calcium homeostasis is an effective measure to reduce toxicity. These studies suggest that the clinical use of EVO-containing herbal medicines should pay due attention to the changes in renal function of patients as well as the off-target effects of the drugs.

BACKGROUND

Evodiamine (EVO) is one of the primary components of Evodia rutaecarpa and has been found to have a positive therapeutic effect on various digestive system diseases. However, no systematic review has been conducted on the research progress and mechanisms of EVO in relation to digestive system diseases, and its toxicity.

PURPOSE

This study aimed to provide a reference for future research in this field.

STUDY DESIGN

A systematic review and meta-analysis of the research progress, mechanisms, and toxicity of EVO in the treatment of digestive system diseases.

METHODS

Five electronic databases were utilized to search for relevant experiments. We conducted a comprehensive review and meta-analysis of the pertinent literature following the guidelines of Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA).

RESULTS

EVO's animal experiments in digestive system diseases primarily focus on colorectal cancer, gastric ulcers, liver cancer, liver fibrosis, ulcerative colitis, colitis-associated cancer, and functional gastrointestinal disorders. EVO also has positive effects on pancreatic cancer, radiation enteritis, gastric cancer, tongue squamous cancer, hepatitis B, oral cancer, and esophageal cancer in vivo. EVO's in cellular experiments primarily focus on SGC7901, HT29, HCT-116, and HepG2 cells. EVO also exhibits positive effects on SW480, LoVo, BGC-823, AGS, COLO-205, MKN45, SMMC-7721, Bel-7402, QGY7-701, PANC-1, SW1990, BxPC-3, HSC4, MC3, HONE1, and CNE1 cells in vitro. The potential common pathways include TGF-β, PI3K-AKT, Wnt, ErbB, mTOR, MAPK, HIF-1, NOD-like receptor, NF-κB, VEGF, JAK-STAT, AMPK, Toll-like receptor, EGFR, Ras, TNF, AGE-RAGE, Relaxin, FoxO, IL-17, Hippo, and cAMP. The mechanisms of EVO on ulcerative colitis, gastric cancer, and HCT116 cells are still controversial in vivo. EVO may have a bidirectional regulatory effect on functional gastrointestinal disorders through calcium signaling. The mechanisms of EVO on HCT116, HT29, SW480, AGS, COLO-205, and SW1990 cells are still controversial in vitro. The question of whether EVO has obvious toxicity is controversial.

CONCLUSION

In both cellular and animal experiments, EVO has demonstrated positive impacts on digestive system diseases. Nevertheless, additional in vivo and in vitro research is required to confirm the beneficial effects and mechanisms of EVO on digestive system diseases, as well as its potential toxicity.

Serum and urine metabolomics based on UPLC-QTOF/MS reveal the effect and potential mechanism of "schisandra-evodia" herb pair in the treatment of Alzheimer's disease

The "schisandra-evodia" herb pair (S-E) is a herbal preparation to treat Alzheimer's disease (AD). This study aims to investigate the therapeutic efficacy and potential mechanism of S-E in AD rats, utilizing pharmacodynamic assessments and serum- and urine-based metabolomic analyses. Pharmacodynamic assessments included Morris water maze test, hematoxylin-eosin staining and immunohistochemistry experiments. The results of the study showed that the AD model was successful; the S-E significantly enhanced long-term memory and spatial learning in AD rats. Meanwhile, S-E notably ameliorated Aβ25-35-induced cognitive impairment, improved hippocampal neuron morphology, decreased Aβ deposition in the hippocampus and mitigated inflammatory damage. We then analyzed serum and urine samples using UPLC-MS/MS to identify potential biomarkers and metabolic pathways. Metabolomic analysis revealed alterations in 40 serum metabolites and 38 urine metabolites following S-E treatment, predominantly affecting pathways related to taurine and hypotaurine metabolism, linoleic acid metabolism, α-linolenic acid metabolism, glycerophospholipid metabolism and arachidonic acid metabolism. This study elucidates the biochemical mechanism underlying AD and the metabolic pathway influenced by S-E, laying the groundwork for future clinical applications.

Evodiamine and its nano-based approaches for enhanced cancer therapy: recent advances and challenges

Evodiamine is a bioactive alkaloid extracted from the Evodia rutaecarpa plant. It has various pharmacological effects including anti-cancer, anti-bacterial, anti-obesity, anti-neurodegenerative, anti-depressant, and cardiac protective properties. Evodiamine demonstrates potent anti-cancer activity by inhibiting the proliferation of cancer cells in vitro and in vivo. Despite the health-promoting properties of evodiamine, its clinical use is hindered by low water solubility, poor bioavailability, and toxicity. Thus, there is a need to develop alternative drug delivery systems for evodiamine to enhance its solubility, permeability, and stability, as well as to facilitate targeted, prolonged, and controlled drug release. Nanocarriers can increase the therapeutic potential of evodiamine in cancer therapy while reducing adverse side effects. To date, numerous attempts have been made through the development of smart nanocarriers to overcome the drawbacks of evodiamine. This review focuses on the pharmacological applications, anti-cancer mechanisms, and limitations of evodiamine. Various nanocarriers, including lipid-based nanoparticles, polymeric nanoparticles, cyclodextrins, and so forth, have been discussed extensively for evodiamine delivery. Nano-drug delivery systems could increase the solubility, bioavailability, stability, and therapeutic efficacy of evodiamine. This review aims to present a comprehensive and critical evaluation of several nano-formulations of evodiamine for cancer therapy. © 2024 Society of Chemical Industry.

The Sishen Pill, a common Chinese patented drug used to treat abdominal pain and diarrhea, consists mainly of Psoraleae Fructus, Myristicae Semen, Euodiae Fructus, and Schisandra Chinensis. Modern research has confirmed that Sishen Pill and its active secondary metabolites, such as psoralen, myristicin, evodiamine, and schisandrin, can improve intestinal inflammation and exert antitumor pharmacological effects. Common mechanisms in treating IBD and colon cancer mainly include regulating inflammation-related signaling pathways such as nuclear factor-kappa B, mitogen-activated protein kinase, phosphatidylinositol 3-kinase, NOD-like receptor heat protein domain-related protein 3, and wingless-type MMTV integration site family; NF-E2-related factor 2 and hypoxia-inducible factor 1α to inhibit oxidative stress; mitochondrial autophagy and endoplasmic reticulum stress; intestinal immune cell differentiation and function through the Janus kinase/signal transducer and activator of transcription pathway; and improving the gut microbiota and intestinal barrier. Overall, existing evidence suggests the potential of the Sishen pill to improve IBD and suppress inflammation-to-cancer transformation. However, large-scale randomized controlled clinical studies and research on the safety of these clinical applications are urgently required.

Evodiamine Inhibits Colorectal Cancer Growth via RTKs Mediated PI3K/AKT/p53 Signaling Pathway

Objective: To investigate the inhibitory effect of EVO on colorectal cancer (CRC) growth and further explore the potential mechanism involving the RTKs-mediated PI3K/AKT/p53 signaling pathway. Methods: Firstly, the inhibitory effect of EVO on CRC cells was detected in vitro by cell viability assay and colony formation assay. The effects of EVO on spatial migration and invasion capacity of cells were detected by Transwell assay. The effects of EVO on apoptosis and cycle of cells were detected by flow cytometry. Then, the molecular mechanism of EVO against CRC was revealed by qRT-PCR and Western blot. Finally, the excellent anti-tumour activity of EVO was verified by in vivo experiments. Results: The results demonstrated that EVO exerts inhibitory effects on CRC cell proliferation, invasion, and colony formation. The cell cycle assay revealed that EVO induces G1/S phase arrest. Through RNA seq, we explored the influence of EVO on the transcriptional profile of colon cancer and observed significant activation of RTKs and the PI3K/AKT pathway, along with its downstream signaling pathways. Furthermore, we observed upregulation of p53 proteins by EVO, which led to the inhibition of Bcl-2 expression and an increase in Bax expression. Consistently, EVO exhibited remarkable suppression of tumor xenograft growth in nude mice. Conclusion: This study confirmed that EVO inhibits the proliferation of CRC cells and promotes cell apoptosis. The possible mechanism of action is inhibiting the expression of the RTK protein family, activating the PI3K/AKT/p53 apoptotic signaling pathway, thereby inhibiting Bcl-2 expression and increasing Bax expression, promoting apoptosis of CRC cells. As a natural product, EVO has very high potential application value.

Evodiamine inhibits growth of vemurafenib drug-resistant melanoma via suppressing IRS4/PI3K/AKT signaling pathway

Evodiamine, a novel alkaloid, was isolated from the fruit of tetradium. It exerts a diversity of pharmacological effects and has been used to treat gastropathy, hypertension, and eczema. Several studies reported that evodiamine has various biological effects, including anti-nociceptive, anti-bacterial, anti-obesity, and anti-cancer activities. However, there is no research regarding its effects on drug-resistant cancer. This study aimed to investigate the effect of evodiamine on human vemurafenib-resistant melanoma cells (A375/R cells) proliferation ability and its mechanism. Cell activity was assessed using the cell counting kit-8 (CCK-8) method. Flow cytometry assay was used to assess cell apoptosis and cell cycle. A xenograft model was used to analyze the inhibitory effects of evodiamine on tumor growth. Bioinformatics analyses, network pharmacology, and molecular docking were used to explore the potential mechanism of evodiamine in vemurafenib-resistant melanoma. RT-qPCR and Western blotting were performed to reveal the molecular mechanism. The alkaloid extract of the fruit of tetradium, evodiamine showed the strongest tumor inhibitory effect on vemurafenib-resistant melanoma cells compared to treatment with vemurafenib alone. Evodiamine inhibited vemurafenib-resistant melanoma cell growth, proliferation, and induced apoptosis, conforming to a dose-effect relationship and time-effect relationship. Results from network pharmacology and molecular docking suggested that evodiamine might interact with IRS4 to suppress growth of human vemurafenib-resistant melanoma cells. Interestingly, evodiamine suppressed IRS4 expression and then inhibited PI3K/AKT signaling pathway, and thus had the therapeutic action on vemurafenib-resistant melanoma.

Advanced application of nanotechnology in active constituents of Traditional Chinese Medicines

Traditional Chinese Medicines (TCMs) have been used for centuries for the treatment and management of various diseases. However, their effective delivery to targeted sites may be a major challenge due to their poor water solubility, low bioavailability, and potential toxicity. Nanocarriers, such as liposomes, polymeric nanoparticles, inorganic nanoparticles and organic/inorganic nanohybrids based on active constituents from TCMs have been extensively studied as a promising strategy to improve the delivery of active constituents from TCMs to achieve a higher therapeutic effect with fewer side effects compared to conventional formulations. This review summarizes the recent advances in nanocarrier-based delivery systems for various types of active constituents of TCMs, including terpenoids, polyphenols, alkaloids, flavonoids, and quinones, from different natural sources. This review covers the design and preparation of nanocarriers, their characterization, and in vitro/vivo evaluations. Additionally, this review highlights the challenges and opportunities in the field and suggests future directions for research. Nanocarrier-based delivery systems have shown great potential in improving the therapeutic efficacy of TCMs, and this review may serve as a comprehensive resource to researchers in this field.

Bioactive phytocompounds for oral cancer prevention and treatment: A comprehensive and critical evaluation

The high incidence of oral cancer combined with excessive treatment cost underscores the need for novel oral cancer preventive and therapeutic options. The value of natural agents, including plant secondary metabolites (phytochemicals), in preventing carcinogenesis and representing expansive source of anticancer drugs have been established. While fragmentary research data are available on antioral cancer effects of phytochemicals, a comprehensive and critical evaluation of the potential of these agents for the prevention and intervention of human oral malignancies has not been conducted according to our knowledge. This study presents a complete and critical analysis of current preclinical and clinical results on the prevention and treatment of oral cancer using phytochemicals. Our in-depth analysis highlights anticancer effects of various phytochemicals, such as phenolics, terpenoids, alkaloids, and sulfur-containing compounds, against numerous oral cancer cells and/or in vivo oral cancer models by antiproliferative, proapoptotic, cell cycle-regulatory, antiinvasive, antiangiogenic, and antimetastatic effects. Bioactive phytochemicals exert their antineoplastic effects by modulating various signaling pathways, specifically involving the epidermal growth factor receptor, cytokine receptors, toll-like receptors, and tumor necrosis factor receptor and consequently alter the expression of downstream genes and proteins. Interestingly, phytochemicals demonstrate encouraging effects in clinical trials, such as reduction of oral lesion size, cell growth, pain score, and development of new lesions. While most phytochemicals displayed minimal toxicity, concerns with bioavailability may limit their clinical application. Future directions for research include more in-depth mechanistic in vivo studies, administration of phytochemicals using novel formulations, investigation of phytocompounds as adjuvants to conventional treatment, and randomized clinical trials.

N(14)-substituted evodiamine derivatives as dual topoisomerase 1/tubulin-Inhibiting anti-gastrointestinal tumor agents

Gastrointestinal tumor is an important factor threatening human health. Natural product-based drug discovery is a popular paradigm for expanding the chemical space and identifying new molecular entities that ameliorate human disease. Evodiamine-inspired medicinal chemistry presents therapeutic potential for treating tumors in different tissues via multi-target inhibition. Here, by focusing on the discovery of anti-gastrointestinal tumor drugs, a series of N(14) alkyl-substituted evodiamine derivatives were designed and synthesized. The structure-activity relationship studies culminated in the identification of the N(14)-propyl-substituted evodiamine analog 6b, which showed low nanomolar inhibitory activity against MGC-803 (IC₅₀ = 0.09 μM) and RKO (IC₅₀ = 0.2 μM) cell lines. Moreover, compound 6b was effective in inducing apoptosis, arresting the cell cycle in the G2/M phase, and inhibiting migration and invasion of MGC-803 and RKO cell lines in a dose-dependent manner in vitro. Further antitumor mechanism studies revealed that compound 6b significantly inhibited topoisomerase 1 (inhibition rate of 58.3% at 50 μM) and tubulin polymerization (IC₅₀ = 5.69 μM). Overall, compound 6b represents a promising dual topoisomerase 1/tubulin-targeting lead structure for the treatment of gastrointestinal tumor.

An A-ring substituted evodiamine derivative with potent anticancer activity against human non-small cell lung cancer cells by targeting heat shock protein 70

The heat shock protein (HSP) system is essential for the conformational stability and function of several proteins. Therefore, the development of efficacious HSP-targeting anticancer agents with minimal toxicity is required. We previously demonstrated that evodiamine is an anticancer agent that targets HSP70 in non-small cell lung cancer (NSCLC) cells. In this study, we synthesized a series of evodiamine derivatives with improved efficacy and limited toxicity. Among the 14 evodiamine derivatives, EV408 (10-hydroxy-14-methyl-8,13,13b,14-tetrahydroindolo [2',3':3,4]pyrido[2,1-b]quinazolin-5(7H)-one) exhibited the most potent inhibitory effects on viability and colony formation under anchorage-dependent and -independent culture conditions in various human NSCLC cells, including those that are chemoresistant, by inducing apoptosis. In addition, EV408 suppressed the cancer stem-like cell (CSC) population of NSCLC cells and the expression of stemness-associated markers. Mechanistically, EV408 inhibited HSP70 function by directly binding and destabilizing the HSP70 protein. Furthermore, EV408 significantly inhibited the growth of NSCLC cell line tumor xenografts without overt toxicity. Additionally, EV408 had a negligible effect on the viability of normal cells. These results suggest the potential of EV408 as an efficacious HSP70-targeting evodiamine derivative with limited toxicity that inhibits both non-CSC and CSC populations in NSCLC.

Plant and fungi derived analgesic natural products targeting voltage-gated sodium and calcium channels

Voltage-gated sodium and calcium channels (VGSCs and VGCCs) play an important role in the modulation of physiologically relevant processes in excitable cells that range from action potential generation to neurotransmission. Once their expression and/or function is altered in disease, specific pharmacological approaches become necessary to mitigate the negative consequences of such dysregulation. Several classes of small molecules have been developed with demonstrated effectiveness on VGSCs and VGCCs; however, off-target effects have also been described, limiting their use and spurring efforts to find more specific and safer molecules to target these channels. There are a great number of plants and herbal preparations that have been empirically used for the treatment of diseases in which VGSCs and VGCCs are involved. Some of these natural products have progressed to clinical trials, while others are under investigation for their action mechanisms on signaling pathways, including channels. In this review, we synthesize information from ~30 compounds derived from natural sources like plants and fungi and delineate their effects on VGSCs and VGCCs in human disease, particularly pain. [Figure: see text].

Histone acetylation modifications: A potential targets for the diagnosis and treatment of papillary thyroid cancer

Thyroid cancer is a common malignancy of the endocrine system, with papillary thyroid cancer (PTC) being the most common type of pathology. The incidence of PTC is increasing every year. Histone acetylation modification is an important part of epigenetics, regulating histone acetylation levels through histone acetylases and histone deacetylases, which alters the proliferation and differentiation of PTC cells and affects the treatment and prognosis of PTC patients. Histone deacetylase inhibitors induce histone acetylation, resulting in the relaxation of chromatin structure and activation of gene transcription, thereby promoting differentiation, apoptosis, and growth arrest of PTC cells.

Evodiamine as an anticancer agent: a comprehensive review on its therapeutic application, pharmacokinetic, toxicity, and metabolism in various cancers

Evodiamine is a major alkaloid component found in the fruit of Evodia rutaecarpa. It shows the anti-proliferative potential against a wide range of cancers by suppressing cell growth, invasion, and metastasis and inducing apoptosis both in vitro and in vivo. Evodiamine shows its anticancer potential by modulating aberrant signaling pathways. Additionally, the review focuses on several therapeutic implications of evodiamine, such as epigenetic modification, cancer stem cells, and epithelial to mesenchymal transition. Moreover, combinatory drug therapeutics along with evodiamine enhances the anticancer efficacy of chemotherapeutic drugs in various cancers by overcoming the chemo resistance and radio resistance shown by cancer cells. It has been widely used in preclinical trials in animal models, exhibiting very negligible side effects against normal cells and effective against cancer cells. The pharmacokinetic and pharmacodynamics-based collaborations of evodiamine are also included. Due to its poor bioavailability, synthetic analogs of evodiamine and its nano capsule have been formulated to enhance its bioavailability and reduce toxicity. In addition, this review summarizes the ongoing research on the mechanisms behind the antitumor potential of evodiamine, which proposes an exciting future for such interests in cancer biology.

The interaction of alkaloids in Coptis chinensis Franch -Tetradium ruticarpum (A. Juss.) T.G. Hartley with hOCT1 and hOCT2

ETHNOPHARMACOLOGICAL RELEVANCE

Zuojin Pill, a traditional poly-herbal drug, comprises Coptis chinensis Franch - Tetradium ruticarpum (A. Juss.) T.G. Hartley (6:1). The significant quantity of alkaloids found in the participating herbs is a key aspect of the Zuojin Pill. According to traditional Chinese medicine (TCM), these numerous alkaloidal compounds within Zuojin Pill have various essential therapeutic effects.

AIM OF THE STUDY

The alkaloids in Tetradium are mainly indole alkaloids, while the alkaloids in Coptis are mostly isoquinoline alkaloids with low bioavailability. Alkaloids and their metabolites are nitrogen-containing compounds or weakly alkaline substances that can be partially ionized under physiological pH conditions. Fortunately, organic cation transporters (OCTs) play a crucial role in the cellular uptake of weakly alkaline compounds. Therefore, we speculated that the alkaloidal compounds might interact with liver cation transporters hOCT1 and kidney cation transporters hOCT2 to alter cell drug disposal. In order to clarify our hypothesis, a series of alkaloids-OCTs interaction experiments were conducted.

MATERIALS AND METHODS

HEK293 cells stably expressing hOCT1 and hOCT2 were modeled and evaluated. Afterward, high-content screening (HCS) was conducted to analyze whether the main alkaloids and their metabolites of Coptis - Tetradium were inhibitors of hOCT1 and hOCT2 transporters. Meanwhile, LC-MS/MS was used to investigate whether the alkaloidal compounds were substrates of hOCT1 and hOCT2 transporters. Finally, drug interactions at the cellular level were assessed by LC-MS/MS after co-administration of berberine and rutacorine.

RESULTS

Berberine, jateorhizine, coptisine, epiberberine, columbamine, demethyleneberberine, and berberrubine could significantly inhibit hOCT1 and hOCT2 activity. Isoquinoline alkaloids, including berberine, jateorhizine, coptisine, epiberberine, columbamine, and palmatine, were substrates of hOCT1 and hOCT2, but not the indole alkaloids evodiamine and rutaecarpine. Furthermore, evodiamine at a concentration of 20 μmol/L had a trivial effect on berberine accumulation in HEK293-hOCT2 cells.

CONCLUSIONS

These results support the idea that alkaloidal compounds within Coptis and Tetradium have hOCT1 and hOCT2 inhibitory activity or be their substrates, and the increased oral bioavailability of berberine in vivo was closely related to the potential interactions of small molecules in Coptis- Tetradium. Overall, our study provides a framework for investigating the potential interactions of small molecules in Coptis- Tetradium.

Evodiamine as the Active Compound of Evodiae fructus to Inhibit Proliferation and Migration of Prostate Cancer through PI3K/AKT/NF-κB Signaling Pathway

Evodiae fructus (EF) is a traditional Chinese medicine which is widely used for the treatment of obesity, inflammation, cardiovascular disease, and diseases of the central nervous system. Recent studies have demonstrated the anticancer property of EF, but the active compounds of EF against prostate cancer and its underlying mechanism remain unknown. In this study, a network pharmacology-based approach was used to explore the multiple ingredients and targets of EF. Through protein-protein interaction (PPI), Gene Ontology (GO) enrichment, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses, the potential targets and corresponding ingredients of EF against prostate cancer cells were obtained. CCK8 and colony formation assays were performed to evaluate the antiproliferative effect of the active compounds on DU145 cells. Cell cycle analysis, Annexin V-FITC/PI staining assay, and Hoechst 33258 staining assay were used to explore the way of evodiamine-induced cell death. The capacities of cell migration after evodiamine treatment were evaluated by wound-healing assay. PharmMapper database was used to predict the potential targets of evodiamine against cancer cell migration. Western blot assay was performed to investigate the signaling pathway through which evodiamine inhibits cell proliferation and migration. The binding of evodiamine to PI3K and AKT was verified by molecular docking. As a consequence, 24 active compounds and 141 corresponding targets were obtained through a network pharmacology-based approach. The results of PPI analysis, GO enrichment, and KEGG pathway enrichment indicated that molecules in the PI3K/AKT/NF-κB signaling pathway were the potential targets of EF against prostate cancer, and evodiamine was the potential active compound. In vitro study demonstrated that evodiamine displays antiproliferative effect on DU145 cells obviously. Evodiamine induces G2/M cell cycle arrest by Cdc25c/CDK1/cyclin B1 signaling. Additionally, evodiamine also promotes mitochondrial apoptosis and inhibits cell migration through PI3K/AKT/NF-κB signaling in DU145 cells. In conclusion, evodiamine is the active compound of EF to inhibit proliferation and migration of prostate cancer through PI3K/AKT/NF-κB signaling pathway, indicating that evodiamine may serve as a potential lead drug for prostate cancer treatment.

Anticancer effects of natural phytochemicals in anaplastic thyroid cancer (Review)

Anaplastic thyroid cancer (ATC) is an aggressive and lethal malignancy having a dismal prognosis. Phytochemicals are bioactive components obtained from plants that have been proven useful to treat numerous diseases. Phytochemicals are also an important source of novel anticancer drugs and an important area of research due to the numerous available candidates that can potentially treat cancers. This review discusses naturally occurring phytochemicals and their derivatives that show promising anticancer effects in anaplastic thyroid cancer. Anticancer effects include cell growth inhibition, induction of apoptosis, promoting cell cycle arrest, suppressing angiogenesis, modulating autophagy, and increasing the production of reactive oxygen species. Phytochemicals are not only prospective candidates in the therapy of anaplastic thyroid cancer but also exhibit potential as adjuvants to improve the anticancer effects of other drugs. Although some phytochemicals have excellent anticancer properties, drug resistance observed during the use of resveratrol and artemisinin in different anaplastic thyroid cancer cell lines is still a problem. Anaplastic thyroid cancer cells have several biological, clinical, and drug-resistance features that differ from differentiated thyroid cancer cells. Phytochemicals such as resveratrol and quercetin exhibit different biological effects in anaplastic thyroid cancer and differentiated thyroid cancer. Tumor cells depend on increased aerobic glycolysis by mitochondrial oxidative phosphorylation to provide energy for their rapid growth, invasiveness, and drug resistance. Phytochemicals can alter signaling cascades, modulate the metabolic properties of cancer cells, and influence the mitochondrial membrane potential of anaplastic thyroid cancer cells. These findings enrich our knowledge of the anticancer effects of phytochemicals and highlight alternative therapies to prevent drug resistance in anaplastic thyroid cancer.

Metabolomics Profiles Associated with the Treatment of Zuojin Pill on Patients with Chronic Nonatrophic Gastritis

Objective: Chronic nonatrophic gastritis (CNG) is the most common digestive disease. In China, Zuojin pill (ZJP) is considered an effective medicine formula for CNG. However, its efficacy and mechanism have never been explored. In order to understand how and why ZJP demonstrates therapeutic effect on CNG, a clinical trial was conducted. Metabolomics was used to explore its deep mechanism.

Methods: A total of 14 patients with CNG were recruited from October 2020 to March 2021 (ChiCTR2000040549). The endoscopy and histopathological changes were evaluated as efficacy. Serum samples were prepared and detected by performing widely targeted metabolome using UPLC. Multivariate statistical analysis was conducted to identify potential differential metabolites and signaling pathways. Last, the signal-related inflammatory factors containing COX-2, IL-4, and IL-17 were confirmed via immunohistochemical staining and enzyme-linked immunosorbent assay.

Results: ZJP was able to alleviate several indexes of mucosal injury under endoscopy and histology. Erosion and bile reflux, but not red plaques and hemorrhage, were downregulated by ZJP. In addition, it could remarkably alleviate active chronic inflammation. A total of 14 potential metabolites, namely, hypoxanthine, adipic acid, D-ribono-1,4-lactone, L-sepiapterin, imidazoleacetic acid, sebacate, ADP-ribose, 4-hydroxybenzyl alcohol, 11,12-EET, 15-OxoETE, 12-OxoETE, (±)8-HETE, glycyrrhizinate, and DL-aminopimelic acid, were discriminated by metabolomics. Moreover, certain amino acid metabolism got significance during the disease progress and treatment. The related inflammatory factors including COX-2, IL-4, and IL-17 were inhibited by ZJP in both mucosa and serum.

Conclusion: All these results indicated that ZJP partially acts as an inflammatory suppressor to regulate comprehensive metabolism disorders. This might be an important mechanism of ZJP in the treatment of CNG.
