Chemical Analysis, Biological Activities, and In Silico Approach of Essential Oils from Leaves, Stem Barks, and Roots of Eupatorium clematideum

The current study first describes a chemical analysis of essential oils from Vietnamese Eupatorium clematideum (Wall. Ex DC.) Sch. Bip. Gas chromatography-mass spectrometry/flame ionization detection analysis revealed α-pinene (16.50%), α-humulene (6.71%-19.05%), germacrene D (7.72%-18.92%), α-santalene (5.61%-14.58%), bicyclogermacrene (8.44%-16.69%), β-caryophyllene (5.50%), and cis-β-elemene (5.71%-9.72%) as the main compounds of essential oils from its leaves, stem barks, and roots. The essential oils from the leaves, stem barks, and roots showed strong cytotoxicity with the corresponding half-maximal inhibitory concentration (IC50) values of 8.43 ± 0.51, 8.74 ± 0.29, and 8.65 ± 0.29 µg/mL against SK-LU-1; 9.42 ± 0.32, 7.93 ± 0.28, and 8.65 ± 0.29 µg/mL against HeLa; and 7.16 ± 0.33, 8.11 ± 0.48, and 9.75 ± 0.41 µg/mL against HepG2 cancer cell lines. The essential oils also exhibited strong inhibitory activity against nitric oxide production with IC50 values of 29.68-33.55 µg/mL. Furthermore, the essential oils exerted antioxidant, antidiabetic, and antimicrobial activities. The molecular docking study revealed that α-santalene and α-humulene displayed the strongest binding affinity for two cancer-related protein targets: epidermal growth factor receptor and human epidermal growth factor receptor 2, respectively. The predicted toxicity profiles of the major compounds were also expected to provide insights for further research considerations.

Wild-Grown Romanian Eupatorium cannabinum: Advancing Phyto-Nanocarriers via Maltodextrin Micro-Spray Encapsulation-Metabolite Profiling, Antioxidant, Antimicrobial, and Cytotoxicity Insights

In Romanian ethnopharmacology, Eupatorium cannabinum species is known for its remarkable biological activity. We present an advanced approach to encapsulation using maltodextrin matrices to enhance the stability and efficacy of phytoconstituents and nanoparticles. Two distinct carrier systems were developed: (i) a direct micro-spray encapsulation of E. cannabinum in maltodextrin to produce a maltodextrin-encapsulated carrier (MEC), and (ii) a two-step process involving the preparation of a new phytocarrier system based on gold nanoparticles (EC-AuNPs), followed by micro-spray encapsulation in maltodextrin to create the maltodextrin-encapsulated AuNPs system (MEC-AuNPs system). Comprehensive chemical profiling using GC-MS and ESI-QTOF-MS revealed 80 bioactive molecules, including terpenoids, alkaloids, flavonoids, and phytoecdysteroids. Morpho-structural (XRD, FTIR, Raman spectroscopy, SEM) and thermal analyses confirmed the successful integration of NPs within the matrices. EC-AuNPs and MEC-AuNPs exhibited superior antioxidant activity, significant antimicrobial efficacy against major bacterial pathogens (S. aureus, B. subtilis, B. cereus, P. aeruginosa, S. typhi, and E. coli), and enhanced cytotoxicity against MCF-7 and HT-29 cancer cell lines. This study highlights the potential of combining E. cannabinum with AuNPs and maltodextrin encapsulation to develop multifunctional therapeutic systems. The findings underscore the importance of phytoconstituent stabilization and nanotechnology in addressing global antimicrobial resistance and advancing innovative medical applications.

The role of non-apoptotic cell death in the treatment and drug-resistance of digestive tumors

Tumor cell apoptosis evasion is one of the main reasons for easy metastasis occurrence, chemotherapy resistance, and the low five-year survival rate of digestive system tumors. Current research has shown that non-apoptotic cell death plays an important role in tumors of the digestive system. Therefore, increasing the proportion of non-apoptotic tumor cells is one of the effective methods of improving therapeutic efficacies for digestive system tumors. Non-apoptotic cell death modes mainly include autophagic cell death, pyroptosis, ferroptosis, in addition to other cell death modes. This review covers a systematic review relating to the research progress made into autophagic cell death, pyroptosis, ferroptosis, and other cell death modes in the treatment of digestive system tumors. It also highlights how treatment is a reasonable prospect based on clinical experience and provides reliable guidance for the further development of digestive system tumor treatments.

Traditional plants from Asteraceae family as potential candidates for functional food industry

Traditional plants have been used in the treatment of disease and pain due to their beneficial properties such as antioxidant, antiinflammation, analgesic, and antibiotic activities. The Asteraceae family is one of the most common groups of plants used in folk medicine. The species Achillea millefolium, Arnica montana, Bellis perennis, Calendula officinalis, Chamaemelum nobile, Eupatorium cannabinum, Helichrysum stoechas, and Taraxacum officinale have been used in different remedies in Northwest Spain. Besides health benefits, some of them like C. nobile and H. stoechas are already employed in cooking and culinary uses, including cocktails, desserts, and savory dishes. This study aimed to review the current information on nutritive and beneficial properties and bioactive compounds of these plants, which are not mainly used as foods but are possible candidates for this purpose. The report highlights their current uses and suitability for the development of new functional food industrial applications. Phenolic compounds, essential oils, and sesquiterpene lactones are some of the most important compounds, being related to different bioactivities. Hence, they could be interesting for the development of new functional foods.

Gut microbiome associated with APC gene mutation in patients with intestinal adenomatous polyps

Background: The 'adenoma-carcinoma sequence' is a well-recognized model of colorectal cancer (CRC) development. However, the interaction between gut microbiota and genetic variation in the initiation of CRC is not clear. Our study attempts to demonstrate the relationship between gut microbiota and host genetics in patients with intestinal adenomatous polyps. Method: The entire exon region of the APC gene was sequenced in 35 patients with pathologically diagnosed adenomatous polyps. Patients with highly pathogenic APC mutation were classified as the case group, while the others were classified as the control group. The patients'stool and serum samples were respectively collected for metagenomics and metabolomics measurements. Results: In the analysis of gut microbiome, there were three most important species, in which Fusobacterium_mortiferum was significantly increased while Faecalibacterium_prausnitzii and Bifidobacterium_pseudocatenulatum were significantly decreased in the case group. The significantly low abundance of the Photosynthesis pathway in patients with APC mutation was due to the low abundance of species Faecalibacterium_prausnitzii and Bifidobacterium_pseudocatenulatum. Moreover, there were two clusters of KEGG pathways correlated with two clusters of species characterized by Faecalibacterium_prausnitzii and Fusobacterium_mortiferum. As to serum metabolomics, the abundance of (R)-3-Hydroxybutyric acid and 2-Hydroxyphenethylamine were significantly higher in patients with APC mutation, while the abundance of 1-Aminocyclopropanecarboxylic acid,7-Ketocholesterol, DL-lactate, and L-Pyroglutamic acid were significantly higher in controlgroup. After analyzing the metabolome and microbiome data by sparCCmethod, we found that there was a significantly negative correlation between the abundance of Faecalibacterium_prausnitzii and Fusobacterium_mortiferum, and a significantly positive correlation between Faecalibacterium_prausnitzii abundance and the steroid hormone Hydrocortisone (Cortisol) in serum. Conclusions: Host's APC mutation was closely related to the changes of gut microbiota and serum metabolites, and some species of gut microbiome like Faecalibacterium_prausnitzii and Fusobacterium_mortiferum might have the potential to predict the development of CRC from intestinal adenomatous polyps.

Medicinal Plants in the Prevention and Treatment of Colon Cancer

The standard treatment for cancer is generally based on using cytotoxic drugs, radiotherapy, chemotherapy, and surgery. However, the use of traditional treatments has received attention in recent years. The aim of the present work was to provide an overview of medicinal plants effective on colon cancer with special emphasis on bioactive components and underlying mechanisms of action. Various literature databases, including Web of Science, PubMed, and Scopus, were used and English language articles were considered. Based on literature search, 172 experimental studies and 71 clinical cases on 190 plants were included. The results indicate that grape, soybean, green tea, garlic, olive, and pomegranate are the most effective plants against colon cancer. In these studies, fruits, seeds, leaves, and plant roots were used for in vitro and in vivo models. Various anticolon cancer mechanisms of these medicinal plants include induction of superoxide dismutase, reduction of DNA oxidation, induction of apoptosis by inducing a cell cycle arrest in S phase, reducing the expression of PI3K, P-Akt protein, and MMP as well; reduction of antiapoptotic Bcl-2 and Bcl-xL proteins, and decrease of proliferating cell nuclear antigen (PCNA), cyclin A, cyclin D1, cyclin B1 and cyclin E. Plant compounds also increase both the expression of the cell cycle inhibitors p53, p21, and p27, and the BAD, Bax, caspase 3, caspase 7, caspase 8, and caspase 9 proteins levels. In fact, purification of herbal compounds and demonstration of their efficacy in appropriate in vivo models, as well as clinical studies, may lead to alternative and effective ways of controlling and treating colon cancer.

Bisphenol A co-exposure effects: a key factor in understanding BPA's complex mechanism and health outcomes

Bisphenol A (BPA) is an environmental endocrine disrupting chemical widely used in the production of consumer products, such as polycarbonate plastics, epoxies, and thermal receipt paper. Human exposure to BPA is ubiquitous due to its high-volume production and use. BPA exposure has been associated with obesity, diabetes, reproductive disorders, and cancer. Yet, the molecular mechanisms or modes of action underlying these disease outcomes are poorly understood due to the pleiotropic effects induced by BPA. A further confounding factor in understanding BPA's impact on human health is that co-exposure of BPA with endogenous and exogenous agents occurs during the course of daily life. Studies investigating BPA exposure effects and their relationship to adverse health outcomes often ignore interactions between BPA and other chemicals present in the environment. This review examines BPA co-exposure studies to highlight potentially unexplored mechanisms of action and their possible associations with the adverse health effects attributed to BPA. Importantly, both adverse and beneficial co-exposure effects are observed between BPA and natural chemicals or environmental stressors in in vitro and in vivo models. These interactions clearly influence cellular responses and impact endpoint measures and need to be considered when evaluating BPA exposures and their health effects.

Evaluation of antiproliferative and protective effects of Eupatorium cannabinum L. extracts

Eupatorium cannabinum L. (Asteraceae) has been used for a long time for medicinal purposes due to its various pharmacological effects and richness in active compounds such as phenolics, sesquiterpenes, pyrrolizidine alkaloids, and polysaccharides. Despite the high content of compounds that have important roles in medicinal plants, there are still limited literature data regarding this valuable species. The plant was fractioned using chloroform (EC) and distilled water (EA) and HPLC analysis revealed the presence of eupatorin, eupatilin, and quercetin in EC and caefic acid and rutin in EA. The antiproliferative potential on BT-20, HepG2, Caco-2, and Jurkat cancer cell lines was assessed by MTS test. Jurkat cells were more sensitive to both extracts (IC50 of 7.35 ± 0.35 for EC and 13.77 ± 2.16 µg/mL for EA), while the other lines were susceptible only to EC (IC50 88.27 ± 1.34 on Caco-2 cells and over 100 µg/mL on BT20 and HepG2 cells) after 24 h of exposure. In an LPS-induced damage mouse model of endotoxemia, we showed that preventive administration increases the survival times of mice and leads to inhibition of proinflammatory cytokines. Both polar and nonpolar compounds are involved in exerting these effects, but further analytical studies are needed to identify the key responsible compounds and their biochemical pathways.

Anticancer effect of fermented Insampaedok-san in human colon cancer cells: a pilot study

Insampaedok-san (IPS) is one of the East Asian traditional medicines which have been prescribed for hundreds of years to treat common cold and headache. Although many herbs and prescriptions are known to have significant activities against diseases, only a limited number of reports and scientific evidences on their efficacies are available. To identify anticancer effect against colon cancer, traditional prescription IPS and its fermented IPS (FIPS) were examined by in vitro molecular biological analysis. IPS water extract was fermented, lyophilized, and examined by cytotoxicity, cell cycle, and western blot assays, using cancer cell lines. Resultantly, FIPS showed significant cytotoxicities inducing caspase dependent apoptosis and activation of caspase-3 (CASP3) and poly (ADP-ribose) polymerase (PARP) cleavage in colon cancer cell line SW620. These findings can be useful for development of anticancer functional food or complementary and alternative medicine, with remaining in-depth molecular functional studies.

Combination of Cinobufacini and Doxorubicin Increases Apoptosis of Hepatocellular Carcinoma Cells through the Fas- and Mitochondria-Mediated Pathways

Cinobufacini, a traditional Chinese medicine, has been used widely for cancer treatment, such as hepatocellular carcinoma (HCC), sarcoma, and leukemia. Previous studies done by our lab indicated that cinobufacini could suppress HCC cells through mitochondria-mediated and Fas-mediated apoptotic pathways. Here, we use a combination of cinobufacini and doxorubicin to inhibit the growth of HCC cells. The combination group induced more significant apoptosis by affecting proteins and RNA of apoptosis-related elements, such as Bcl-2, Bax, Bid, and cytochrome c. Furthermore, cinobufacini, as a mixture of a number of components, had stronger apoptosis-inducing activity than particular individual components or a simple mixture of a few components. Overall, these results suggested that the combination of cinobufacini and doxorubicin may provide a new strategy for inhibiting the proliferation of HCC cells.
