Long-term effects of evodiamine on expressions of lipogenesis and lipolysis genes in mouse adipose and liver tissues

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.

Folate Functionalized and Evodiamine-Loaded Pluronic Nanomicelles for Augmented Cervical Cancer Cell Killing

Evodiamine (Evo) is a natural, biologically active plant alkaloid with wide range of pharmacological activities. In the present study Evo-loaded folate-conjugated Pluronic F108 nano-micelles (ENM) is synthesized to enhance the therapeutic efficacy of Evo against cervical cancer. ENM are synthesized, physicochemically characterized and in vitro anticancer activity is performed. The study demonstrates that ENM have nanoscale size (50.33 ± 3.09 nm), monodispersity of 0.122 ± 0.072, with high drug encapsulation efficiency (71.30 ± 3.76%) and controlled drug release at the tumor microenvironment. ENM showed dose-dependent and time-dependent cytotoxicity against HeLa human cervical cancer cells. The results of in vitro anticancer studies demonstrated that ENM have significant anticancer effects and greatly induce apoptosis as compared to pure Evo. The cellular uptake study suggests that increased anticancer activity of ENM is due to the improved intracellular delivery of Evo through overexpressed folate receptors. Overall, the designed ENM can be a potential targeted delivery system for hydrophobic anticancer bioactive compound like Evo.

Proteomic analysis of evodiamine-induced cytotoxicity in thyroid cancer cells

Evodiamine is a natural product extracted from herbal plants such as Tetradium which has shown to have anti-fat uptake and anti-proliferation properties. However, the effects of evodiamine on the behavior of thyroid cancers are largely unknown. To determine if evodiamine might be useful in the treatment of thyroid cancer and its cytotoxic mechanism, we analyzed the impact of evodiamine treatment on differential protein expression in human thyroid cancer cell line ARO using lysine-labeling two-dimensional difference gel electrophoresis (2D-DIGE) combined with mass spectrometry (MS). This study demonstrated 77 protein features that were significantly changed in protein expression and revealed evodiamine-induced cytotoxicity in thyroid cancer cells involves dysregulation of protein folding, cytoskeleton, cytoskeleton regulation and transcription control. Our work shows that this combined proteomic strategy provides a rapid method to study the molecular mechanisms of evodiamine-induced cytotoxicity in thyroid cancer cells. The identified targets may be useful for further evaluation as potential targets in thyroid cancer therapy.

Add-on therapy with traditional Chinese medicine: An efficacious approach for lipid metabolism disorders

Add-on therapy with traditional Chinese medicine (TCM) has been extensively researched in the intractable diseases, such as asthma, cancer, and Alzheimer's disease. As an entirely new concept, add-on therapy of TCM has been also used to prevent and treat hyperlipidemia via lowering cholesterol level. However, the efficacy of add-on therapy with TCM for mediating lipid metabolism disorders remains controversial. In this review, we summarize and provide strong evidence that add-on therapy of TCM as a novel approach is efficacious and safe for hyperlipidemia associated diseases based on the mediation of lipid metabolism disorders.

Combination of berberine and evodiamine inhibits intestinal cholesterol absorption in high fat diet induced hyperlipidemic rats

BACKGROUND

Hyperlipidemia characterized of elevated serum lipid levels is a prevalent disease frequently resulting in cardiovascular disease (CVD). Berberine and evodiamine are herbal products of traditional Chinese herb Coptis chinensis and Evodia rutaecarpa, which are indicated to exert regulation of lipid metabolism. Therefore, the objective of this study was to investigate the lipid-lowering effect of berberine and evodiamine combination in hyperlipidemic rats.

METHOD

The rat model of hyperlipidemia was established by providing high-fat-diet (HFD) for 4 weeks. Berberine (BB), evodiamine (EV), and their combination (BB + EV) were orally administered to HFD induced rats for 4 weeks. Body weight, food utilization, histopathology of liver tissues, lipid profiles of serum and liver were measured. Gas chromatography (GC) analysis was applied to examine the level of plasma total cholesterol and ß- Sitosterol (BS) to estimate cholesterol absorption activity. Furthermore, intestinal NPC1L1, ACAT2, and ApoB48 protein expressions were evaluated by immunohistochemical assay.

RESULT

According to the results, decreased levels of serum cholesterol (TC), triglycerides (TG), low density lipoprotein-cholesterol (LDL-C), as well as hepatic TC were showed in hyperlipidemic rats treated by combination of berberine and evodiamine. GC analysis indicated that the elevated plasma BS was significantly ameliorated by BB, EV, and BB + EV. In addition, immunohistochemical analysis revealed that BB + EV treatment down-regulated the expressions of intestinal NPC1L1 and ACAT2, and ApoB48 in HFD induced rats.

CONCLUSION

Based on the above results, combination of berberine and evodiamine exerted a promising preventive effect on hyperlipidemia, partially through inhibiting intestinal absorption of cholesterol.

Evodiamine inhibits invasion and metastasis of human hepatocellular carcinoma HepG2 cells

AIM: To assess the effect of evodiamine on the invasion and metastasis of human hepatocellular carcinoma HepG2 cells and to discuss the underlying mechanism.

METHODS: The effect of evodiamine on the expression levels of ERK1/2 and p-ERK1/2 in HepG2 cells was assessed by Western blot. The invasion and metastasis of HepG2 cells were tested by transwell assays. Colony-forming ability was determined by colony formation assay.

RESULTS: After HepG2 cells were treated with 0, 5, 25, or 50 μmol/L evodiamine, the numbers of invasion cells were 97.6 ± 6.3, 32.3 ± 1.3, 22.3 ± 2.5, and 10.6 ± 3.7, respectively, and the numbers of metastatic cells were 106.3 ± 3.2, 57.7 ± 3.2, 26.8 ± 1.6, and 15.4 ± 3.9, respectively (P < 0.05). Evodiamine had a significant inhibitory effect on HepG2 cell colony-forming ability (P < 0.05). Evodiamine treatment down-regulated the expression of p-ERK1/2, but had no significant impact on ERK1/2 expression.

CONCLUSION: Evodiamine can inhibit the invasion, metastasis and colony-forming ability of human hepatocellular carcinoma HepG2 cells, and the possible mechanism may be related to down-regulation of p-ERK 1/2 protein.
