Abstract
Cancer, a complex and multifactorial disease, presents a significant challenge to global health. Despite significant advances in surgical, radiotherapeutic and immunological approaches, which have improved cancer treatment outcomes, drug therapy continues to serve as a key therapeutic strategy. However, the clinical efficacy of drug therapy is often constrained by drug resistance and severe toxic side effects, and thus there remains a critical need to develop novel cancer therapeutics. One promising strategy that has received widespread attention in recent years is drug repurposing: the identification of new applications for existing, clinically approved drugs. Drug repurposing possesses several inherent advantages in the context of cancer treatment since repurposed drugs are typically cost-effective, proven to be safe, and can significantly expedite the drug development process due to their already established safety profiles. In light of this, the present review offers a comprehensive overview of the various methods employed in drug repurposing, specifically focusing on the repurposing of drugs to treat cancer. We describe the antitumor properties of candidate drugs, and discuss in detail how they target both the hallmarks of cancer in tumor cells and the surrounding tumor microenvironment. In addition, we examine the innovative strategy of integrating drug repurposing with nanotechnology to enhance topical drug delivery. We also emphasize the critical role that repurposed drugs can play when used as part of a combination therapy regimen. To conclude, we outline the challenges associated with repurposing drugs and consider the future prospects of these repurposed drugs transitioning into clinical application.

Ren K, Zhang X, Wang R, Ren S, Hua H, Wang D, Pan Y, Liu X. The inhibitory effect of licorice on the hepatotoxicity induced by the metabolic activation of Euodiae Fructus. JOURNAL OF ETHNOPHARMACOLOGY 2024; 319:117233. [PMID: 37793580 DOI: 10.1016/j.jep.2023.117233] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Revised: 09/12/2023] [Accepted: 09/25/2023] [Indexed: 10/06/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Euodiae Fructus (EF), the dried, unripe, scented fruit of Tetradium ruticarpum (A. Juss, T.G.Hartley), is a traditional food and herb with mild toxicity. In Asia, it is processed with licorice (EFP), which has been used for centuries to alleviate pain and suppress cough. Pharmacological studies have reported that this herb could cause liver injury by activating the P450 3A enzyme, thus carrying the risk of clinical application. Processing with licorice is an effective method to reduce EF toxicity. It is urgent to explore the toxic components of EF and the attenuation mechanism of licorice. AIM OF THE STUDY This study aimed to indicate the specific pathway of EF-induced damage and identify the mechanism of action of licorice in reducing P450 activation and resulting in reduced liver damage. MATERIALS AND METHODS Male C57BL-6 mice were used to investigate the toxicity of EF to the liver and determine the attenuation effect on P450 from licorice ingestion. Glutathione (GSH) was used to capture the metabolic activation intermediates of EF. The key component reducing the EF toxicity of licorice was investigated by comparing the differences in chemical components and inhibition on the EF metabolism of licorice from different habitats. RESULTS The intermediate product of evodiamine (EVO) in EF was found to be activated by the P450 enzyme during metabolism, causing liver injury and inflammation. Isoliquiritigenin and liquiritigenin in licorice produced by intestinal bacterial metabolism and glycyrrhizin inhibited the metabolic activation of EF. Glycosides in licorice are metabolized into aglycones by intestinal bacteria, inhibiting the metabolic activation of EF and alleviating hepatotoxicity. CONCLUSIONS By combining with GSH, the electrophilic intermediates produced by the P450 enzyme's metabolic activation of the indole ring of EVO might cause hepatotoxicity. Glycyrrhizin from licorice and the liquiritigenin and isoliquiritigenin generated by intestinal bacterial metabolism play an attenuated function by inhibiting the P450 enzyme and preventing the metabolic activation of EF.

Elucidation of the relationship between evodiamine-induced liver injury and CYP3A4-mediated metabolic activation by UPLC-MS/MS analysis. Anal Bioanal Chem 2023; 415:5619-5635. [PMID: 37433953 DOI: 10.1007/s00216-023-04831-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 06/03/2023] [Accepted: 06/27/2023] [Indexed: 07/13/2023]
Abstract
Evodiamine (EVD), which has been reported to cause liver damage, is the main constituent of Evodia rutaecarpa (Juss.) Benth and may be bioactivated into reactive metabolites mediated by cytochrome P450. However, the relationships between bioactivation and EVD-induced hepatotoxicity remain unknown. In this study, comprehensive hepatotoxicity evaluation was explored, which demonstrated that EVD caused hepatotoxicity in both time- and dose-dependent manners in mice. By application of UPLC-Q/TOF-MS/MS, two GSH conjugates (GM1 and GM2) derived from reactive metabolites of EVD were identified, in microsomal incubation systems exposed to EVD with glutathione (GSH) as trapping agents. CYP3A4 was proved to be the main metabolic enzyme. Correspondingly, the N-acetyl-L-cysteine conjugate derived from the degradation of GM2 was detected in the urine of mice after exposure to EVD. For the first time, the iminoquinone intermediate was found in EVD-pretreated rat bile by the high-resolution MS platform. Pretreatment with ketoconazole protected the animals from hepatotoxicity, decreased the protein expression of cleaved caspase-1 and -3, but increased the area under the serum-concentration-time curve of EVD in blood determined by UPLC-QQQ-MS/MS. Depletion of GSH by buthionine sulfoximine exacerbated EVD-induced hepatotoxicity. These results implicated that the CYP3A4-mediated metabolic activation was responsible for the observed hepatotoxicity induced by EVD.

Resting Metabolic Rate for Diagnosing Tae-Eum Sasang Type and Unraveling the Mechanism of Type-Specific Obesity. Diagnostics (Basel) 2023; 13:diagnostics13040672. [PMID: 36832160 PMCID: PMC9955353 DOI: 10.3390/diagnostics13040672] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2022] [Revised: 02/06/2023] [Accepted: 02/06/2023] [Indexed: 02/17/2023] Open
Abstract
Increased resting metabolic rate (RMR), representing augmented energy expenditure, is a preferred physical characteristic; however, the Tae-Eum Sasang type, with a high incidence of obesity and metabolic diseases, has a higher RMR. This study scrutinized the physical characteristics of Sasang typology, a traditional Korean personalized medicine, to resolve this discrepancy, which can unravel the mechanism of Tae-Eum-type-specific obesity and improve the Tae-Eum Sasang-type diagnosis. A total of 395 healthy participants provided Sasang-type diagnosis using Sasang Constitutional Analysis Tool and physical features, including skeletal muscle mass, body fat mass, and RMR, along with those standardized using body weight. The Tae-Eum-type group showed significantly higher body weight, body mass index, body fat mass, and unstandardized RMR (kcal/day) than others, while their standardized measures of RMR per weigh (RMRw, kcal/day/kg) and percent skeletal muscle (PSM, %) were significantly lower. The logistic regression model revealed that the RMRw is pivotal for discriminating Tae-Eum type from others and explaining the developmental mechanism of Tae-Eum-type obesity. The aforementioned might provide a theoretical framework for Sasang-type diagnosis and Sasang-type-specific health promotion using bodily exercise and medical herbs.

Abstract
Guidelines for preclinical drug development reduce the occurrence of arrhythmia-related side effects. Besides ample evidence for the presence of arrhythmogenic substances in plants, there is no consensus on a research strategy for the evaluation of proarrhythmic effects of herbal products. Here, we propose a cardiac safety assay for the detection of proarrhythmic effects of plant extracts based on the experimental approaches described in the Comprehensive In vitro Proarrhythmia Assay (CiPA). Microelectrode array studies (MEAs) and voltage sensing optical technique on human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) were combined with ionic current measurements in mammalian cell lines, In-silico simulations of cardiac action potentials (APs) and statistic regression analysis. Proarrhythmic effects of 12 Evodia preparations, containing different amounts of the hERG inhibitors dehydroevodiamine (DHE) and hortiamine were analysed. Extracts produced different prolongation of the AP, occurrence of early after depolarisations and triangulation of the AP in hiPSC-CMs depending on the contents of the hERG inhibitors. DHE and hortiamine dose-dependently prolonged the field potential duration in hiPSC-CMs studied with MEAs. In-silico simulations of ventricular AP support a scenario where proarrhythmic effects of Evodia extracts are predominantly caused by the content of the selective hERG inhibitors. Statistic regression analysis revealed a high torsadogenic risk for both compounds that was comparable to drugs assigned to the high-risk category in a CiPA study.

Abstract
Obesity is a chronic metabolic disease caused by excessive body fat and has become a global public health problem. Evidence suggests that obesity and obesity-induced metabolic disorders are closely related to gut microbiota. Bupropion (BP), an antidepressant medicine, and Ephedra sinica Stapf [Ephedraceae; Ephedrae Herba], a herbal medicine, are sympathetic stimulants and have weight loss effects. However, to our best knowledge, no studies have simultaneously assessed the effects of drugs and herbal medicines on obesity and gut microbiota. This study aimed to determine the effects of BP and ES on weight loss and re-modulation of host gut microbiota. To test this hypothesis, we fed C57BL/6J mice with a high-fat diet supplemented with bupropion (BP; 30 mg/kg/day) and Ephedra sinica Stapf extract (ES; 150 mg/kg/day) via oral gavage for eight weeks. Further, we evaluated the effects of BP and ES on body weight and fat accumulation. In addition, we evaluated the effects of BP and ES on gut microbiota using 16S rRNA amplicon sequencing. Our results showed that weight loss was confirmed in both BP and ES; however, it was more pronounced in ES. ES changed the overall composition of the gut microbiota by restoring the relative abundance of Oscillospiraceae, Lachnospiraceae, and the Firmicutes/Bacteroidetes ratio, an indicator of gut microbiota dysbiosis. Nine amplicon sequence variants (ASVs) of the gut microbiome were significantly recovered by BP and ES treatment, of which eight ASVs correlated with body weight and fat accumulation. Additionally, three ASVs were significantly recovered by ES treatment alone. In conclusion, the anti-obesity effects of BP and ES, especially fat accumulation, are related to the regulation of gut microbiota. Moreover, ES had a greater influence on the gut microbiota than BP.

Abstract
Background: The prevalence of obesity is increasing worldwide, causing a global health issue. Traditional Chinese medicine (TCM) used in treating overweight/obesity has been widely implemented in clinical practice, but its overall efficacy and safety remain unclear. This review aims to evaluate the effectiveness and safety of TCM based on randomized controlled trials (RCTs).Methods: A systematic review was conducted by searching PubMed, Cochrane Library, Web of Science, Embase, and Clinical Trails from their inception to March 2021. Two reviewers screened studies, extracted the data, and assessed the risk of bias independently. The data were pooled for meta-analysis or presented narratively.Results: Twenty-five RCTs involving 1,947 participants were included. Compared with placebo or blank control, TCM preparations reduced Body Mass Index (BMI) [MD = −1.16; 95% confidence interval (CI) = −1.44, −0.89; I2 = 34%], reduced weight (MD = −2.53; 95% CI = −3.08, −1.99; I2 = 34%), reduced waist circumference (MD = −2.64; 95% CI = −3.42, −1.87; I2 = 0%), reduced hip circumference (MD = −3.48; 95% CI = −4.13, −2.83; I2 = 0%), reduced total cholesterol (TCHO) (MD = −10.45; 95% CI = −18.92, −1.98; I2 = 63%), reduced triglycerides (TG) (MD = −4.19; 95% CI = −6.35, −2.03; I2 = 25%), increased high-density lipoprotein (HDL) (MD = −3.60; 95% CI = −6.73, −0.47; I2 = 81%), reduced fasting blood glucose (FBG) (MD = −0.77; 95% CI = −1.24, −0.29; I2 = 91%). Glycated hemoglobin (HbA1c)、body fat rate、low-density lipoprotein (LDL) were not statistically significant. For people with hypertension, decreased systolic blood pressure (SBP) (MD = −5.27; 95% CI = −8.35, −2.19; I2 = 58%), decreased diastolic blood pressure (DBP) (MD = −4.30; 95% CI = −5.90, −2.69; I2 = 0%). For people with normal blood pressure, there was no significant change. There was no significant difference in liver function.Conclusion: It has been demonstrated that TCM preparations have good clinical efficacy and safety for overweight/obesity. TCM may be suitable for overweight/obesity in adult populations for its efficacy and safety of long-term treatment.

Abstract
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.

Abstract
BACKGROUND Obesity has become a serious global health problem due to its increasing prevalence. Because of several limitations or adverse events associated with conventional western medicine therapies, there has been an increase in demand for alternative therapies such as traditional East Asian medicine (TEAM). This study aims to provide comprehensive evidence-based information assessing the clinical efficacy and safety of TEAM treatment for obesity as the basis for reliable clinical strategies for patients with obesity. METHODS Electronic searches of the PubMed, Cochrane Library, EMBASE, China National Knowledge Infrastructure, OASIS, and Korea Citation Index will be performed. Methodological quality will be assessed using the "risk of bias" tool. The primary outcome for efficacy will be weight loss. The secondary outcomes will be response rate, body mass index, waist circumference, and blood pressure. We will also evaluate the rates of adverse events and mortality for safety assessment. First, we will conduct a conventional pairwise meta-analysis. Next, we will conduct network meta-analysis using the frequentist approach. We shall verify the assumption of network meta-analysis and provide network geometry, P-score, net league table, and intervention-based forest plot. A subgroup analysis will be conducted to ascertain the factors that affect treatment, such as dosage, treatment duration, and severity of obesity. RESULTS The results of this study will provide high-quality systematic reviews that can assist decision making in obesity management. Our network meta-analysis results can provide direct and indirect comparison evidence on comparative efficacy and safety. CONCLUSION This study will provide fundamental data for prospective research on the application of TEAM in patients with obesity.

Abstract
The natural alkaloid evodiamine enhances cholesterol efflux from cultured THP-1-derived macrophages, but whether it has any impact on blood lipids in vivo remains unknown. In this study, the effect of evodiamine on hyperlipidemia induced by a high-fat diet (HFD) was investigated in mice. Intragastric administrations of evodiamine (10 and 20 mg/kg) for 8 weeks resulted in a significant improvement of metabolic lipid profiles by reducing the plasma levels of triglycerides (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C). Evodiamine also significantly decreased hepatic lipid accumulation and hepatic total bile acids (TBA). Mechanistically, evodiamine increased ATP-binding cassette transporter G1 (ABCG1) mRNA and protein expression and up-regulated peroxisome proliferator-activated receptor gamma (PPARγ) expression in the liver. Taken together, the natural product evodiamine lowers blood lipids in HFD-fed mice likely through promoting the PPARγ-ABCG1 signaling pathway.

Abstract
Obesity is a low-grade systemic inflammatory disease involving adipocytokines. As though Anmyungambi decoction (AMGB) showed significant improvement on obesity in a clinical trial, the molecular mechanism of AMGB in obesity remains unknown. Therefore, we explored the potential mechanisms of action of AMGB on obesity through network pharmacological approaches. We revealed that targets of AMGB are significantly associated with obesity-related and adipocyte-elevated genes. Evodiamine, berberine, genipin, palmitic acid, genistein, and quercetin were shown to regulate adipocytokine signaling pathway proteins which mainly involved tumor necrosis factor receptor 1, leptin receptor. In terms of the regulatory pathway of lipolysis in adipocytes, norephedrine, pseudoephedrine, quercetin, and limonin were shown to affect adrenergic receptor-beta, protein kinase A, etc. We also found that AMGB has the potentials to enhance the insulin signaling pathway thereby preventing type II diabetes mellitus. Additionally, AMGB was discovered to be able to control not only insulin-related proteins but also inflammatory mediators and apoptotic regulators and caspases, hence reducing hepatocyte injury in nonalcoholic fatty liver disease. Our findings help develop a better understanding of how AMGB controls obesity.

Abstract
Euodiae Fructus (EF), the dried unripe scented fruit of Euodia rutaecarpa (Juss.) Benth., was reported to show anti-hypertensive, antitumor, and anti-obesity effects. The main alkaloids of EF were reported as the reason for toxicity of EF by metabolic activation majority through CYP3A. Up till the present moment, the cytotoxicity mechanisms of EF have not yet to be fully clarified. For the purposes of this article, the influence of CYP3A inducer and inhibitor on cytotoxicity of EF and metabolism in L02 cells of five alkaloids related to toxicity of EF were evaluated. The results indicated that CYP3A inducer aggravated the toxicity and CYP3A inhibitor alleviated the toxicity. UPLC-Q-Exactive-MS was used for the identification of five alkaloids of EF in L02 cells. A total of 13 metabolites were detected in L02 cells. In general, five alkaloids were widely metabolized in L02 cells such as oxygenation, demethylation, dehydrogenation, and etc. In addition, oxygenation was the main metabolic pathway. It was inferred that the toxicity of EF was closely related to the CYP3A and the metabolic intermediate might be one of the reasons for the toxicity of EF. Hence, the choice of optimal dose might be critical to avoid the adverse reactions owing to combination of EF and CYP3A inducer.

Abstract
Ephedra sinica (ES) is a promising medicinal plant with a wide range of pharmacological aspects, including antioxidant and anti-inflammatory properties. Fipronil (FN) is a popularly used systemic insecticide in agriculture and veterinary applications. FN exposure can result in a variety of negative health consequences. The study aimed to explore the prophylactic effects of Ephedra sinica extract (ESE) against hepatotoxicity in FN-treated rats by following the TLR4/ MyD88/ NF-κB pathway. ESE was tested for polyphenolic and antioxidant activity. Forty rats were separated into four groups and given orally by FN (10 mg/kg B.W.) and/or ESE (150 mg/kg B.W.). Blood and tissue samples were collected at the end of the experiment and prepared for pathophysiological, gene expression, and pathological analysis. ESE showed strong antioxidant activity, as well as reduced levels of hepatic MDA and oxidative stress markers (H2O2, NO). Hepatic SOD and CAT activities were increased even further. Furthermore, in FN-treated rats, ESE improved liver functions (ALT, AST, ALP, and LDH) and recovered the lipid profile (Cho, TriG, HDL, and LDL). Moreover, by inhibiting TLR4/ MyD88/ NF-κB induction, ESE alleviated hepatic pathological changes and decreased FN-induced elevations of TNF-α, IL-6, and IL-1β mRNA/protein levels. These findings suggested that ESE mitigated FN-induced hepatotoxicity via combating oxidative stress and relieving inflammation.

Abstract
OBJECTIVE Dietary supplements and alternative therapies are commercialized as a panacea for obesity/weight gain as a result of the minimal regulatory requirements in demonstrating efficacy. These products may indirectly undermine the value of guideline-driven obesity treatments. Included in this study is a systematic review of the literature of purported dietary supplements and alternative therapies for weight loss. METHODS A systematic review was conducted to evaluate the efficacy of dietary supplements and alternative therapies for weight loss in participants aged ≥18 years. Searches of Medline (PubMed), Cochrane Library, Web of Science, CINAHL, and Embase (Ovid) were conducted. Risk of bias and results were summarized qualitatively. RESULTS Of the 20,504 citations retrieved in the database search, 1,743 full-text articles were reviewed, 315 of which were randomized controlled trials evaluating the efficacy of 14 purported dietary supplements, therapies, or a combination thereof. Risk of bias and sufficiency of data varied widely. Few studies (n = 52 [16.5%]) were classified as low risk and sufficient to support efficacy. Of these, only 16 (31%) noted significant pre/post intergroup differences in weight (range: 0.3-4.93 kg). CONCLUSIONS Dietary supplements and alternative therapies for weight loss have a limited high-quality evidence base of efficacy. Practitioners and patients should be aware of the scientific evidence of claims before recommending use.

Involvement of serotonergic pathways in gastric dysmotility induced by fat burning nutritional supplements in mice. CURRENT RESEARCH IN PHARMACOLOGY AND DRUG DISCOVERY 2021; 2:100018. [PMID: 34909653 PMCID: PMC8663933 DOI: 10.1016/j.crphar.2021.100018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2020] [Revised: 01/20/2021] [Accepted: 02/01/2021] [Indexed: 11/30/2022] Open
Abstract
Fat burners are a category of nutritional supplements that are claimed to increase the metabolism and promote greater energy expenditure, leading to weight loss. However, little is known about the side effects on gastrointestinal motility. In this study, we evaluated the effect of ingestion with a fat burner named Thermbuterol® (THERM) on the gastric motility and food behavior of mice. THERM compounds were identified using nuclear magnetic resonance (NMR). Mice received variable doses of THERM (10, 50, 100 or 300 mg/kg, p.o.) or NaCl 0.15 M (control). Gastric emptying (GE) was assessed using the phenol red technique. Another set of mice was pretreated with intraperitoneal administration of hexamethonium (HEXA, 10 mg/kg), prazosin (PRAZ, 0.25 mg/kg), propranolol (PROP, 2 mg/kg), parachlorophenylalanine (PCPA, 300 mg/kg) or ondansetron (ONDA, 50 μg/kg) 30 min before THERM treatment for evaluation of GE. We assessed the gastrointestinal responsiveness in vitro as well as THERM's effects on food behavior. Caffeine was the major compound of THERM, identified by NMR. THERM 100 and 300 mg/kg decreased GE compared to the respective controls. Pretreatment with PRAZ or PROP did not prevent gastric dysmotility induced by THERM 100 mg/kg. However, the pretreatment with HEXA, ONDA or PCPA prevented GE delay induced by THERM. In vitro, THERM relaxed contractions in strips of longitudinal gastric fundus and duodenum. THERM also increased food intake, which was prevented by PCPA and ONDA treatments. THERM decreased GE of a liquid and increased food intake in mice, a phenomenon mediated by the autonomic nicotinic receptors and serotoninergic receptor.

JOURNAL OF ETHNOPHARMACOLOGY 2021; 264:113277. [PMID: 32810616 DOI: 10.1016/j.jep.2020.113277] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/19/2020] [Revised: 07/21/2020] [Accepted: 08/10/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Evodiae Fructus (EF), the traditional Chinese medicine, has been typically used to treat headache, abdominal pain, hernias, and menorrhagia for thousands of years. It is a mild toxicity herb-medicine listed in Sheng Nong's Herbal Classic. Recently, EF was reported to have toxicity or no toxicity in some investigations. Toxicity and approaches to reducing toxicity of EF are of great interest. Limonin (LIM), a major triterpenoid component of EF, also had various pharmacological activities such as anti-inflammatory, anticancer, and antioxidant effects. However, little attention was paid to the role of LIM in EF-induced hepatotoxicity. AIM OF STUDY The study aimed to address the problem of controversial hepatotoxicity of EF, evaluate the role of CYP3A4 inducer/inhibitor in EF-induced hepatotoxicity and disclose the effect of LIM in EF-induced hepatotoxicity. MATERIALS AND METHODS The chemical compositions and hepatotoxicity of small flower EF (SEF), medium flower EF (MEF), big flower EF (BEF) and the "organ knock-out" samples (the shell and seed part of BEF) were investigated. Simultaneously, C57BL-6 mice were randomly divided into four groups, which were given orally administered BEF, BEF in combination with dexamethasone (DEX), BEF in combination with ketoconazole (KTC), and BEF in combination with LIM, respectively. RESULTS In this study, more alkaloids and less LIM were detected in BEF compared with the compounds in SEF and MEF. Furthermore, we found that BEF group induced hepatotoxicity whereas no hepatotoxicity was observed in SEF and MEF groups. In addition, no LIM was detected in the shell part of BEF and five alkaloids were not detected in the seed part of BEF. Correspondingly, the shell part of BEF group induced hepatotoxicity whereas no hepatotoxicity was observed in the seed part of BEF group. It was also found that the BEF-induced hepatotoxicity was remarkably exacerbated when the mice were pretreated with DEX whereas the BEF-induced hepatotoxicity could be reversed by pretreatment with KTC or LIM. CONCLUSIONS Based on the results in this study, the misuse of BEF but not SEF and MEF could produce hepatotoxicity. The hepatotoxicity difference of different categories of EF might be associated with the relative contents of alkaloids and LIM. In addition, the results demonstrated that CYP3A4 inducer aggravated BEF-induced hepatotoxicity and LIM attenuated its hepatotoxicity.

Abstract
This review focuses on four new product categories of food supplements: pre-workout, fat burner/thermogenic, brain/cognitive booster, and hormone/testosterone booster. Many food supplements have been shown to be contaminated with unauthorized substances. In some cases, the ingredients in the new categories of dietary supplements were medicinal products or new synthetic compounds added without performing clinical trials. Some of the new ingredients in dietary supplements are plant materials that are registered in the pharmacopoeia as herbal medicines. In other cases, dietary supplements may contain plant materials that have no history of human use and are often used as materials to 'camouflage' stimulants. In the European Union, new ingredients of dietary supplements, according to European Food Safety Authority or unauthorized novel food. Furthermore, selected ingredients in dietary supplements may be prohibited in sports and are recognized as doping agents by World Anti-Doping Agency.

Abstract
AIM To update the available evidence on the efficacy and safety of complementary medicines to assist in weight loss by conducting a systematic review and meta-analysis of herbal medicines for weight loss. METHODS Four electronic databases (Medline, Embase, CINAHL and Web of Science) were searched from inception until August 2018. A total of 54 randomized placebo-controlled trials of healthy overweight or obese adults were identified. Meta-analyses were conducted for herbal medicines with ≥4 studies available. Weight differences of ≥2.5 kg were considered clinically significant. RESULTS As a single agent, only Phaseolus vulgaris resulted in a statistically significant weight loss compared to placebo, although this was not considered clinically significant. No effect was seen for Camellia sinensis or Garcinia cambogia. Statistically, but not clinically, significant differences were observed for combination preparations containing C. sinensis, P. vulgaris or Ephedra sinica. Of the herbal medicines trialled in ≤3 randomized controlled trials, statistically and clinically significant weight loss compared to placebo was reported for Irvingia gabonensis, Cissus quadrangularis, and Sphaeranthus indicus combined with Garcinia mangostana, among others, but these findings should be interpreted cautiously because of the small number of studies, generally poor methodological quality, and poor reporting of the herbal medicine interventions. Most herbal medicines appeared safe for consumption over the short duration of the studies (commonly ≤12 weeks). Some warrant further investigation to determine effect size, dosage and long-term safety. CONCLUSION There is currently insufficient evidence to recommend any of the herbal medicines for weight loss included in the present review.

[PMID: 31905825 PMCID: PMC7020418 DOI: 10.3390/toxins12010016] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2019] [Revised: 12/14/2019] [Accepted: 12/27/2019] [Indexed: 12/26/2022] Open
Abstract
Ephedra sinica Stapf (EH) exert toxic effects, such as excitability, cardiac arrhythmia, and others. On the contrary, in traditional herbal medicine, EH and gypsum (GF) are used most often to treat symptoms caused by external stressors. The hypothalamus plays a crucial role in thermal homeostasis. Inflammatory response in the hypothalamus by thermal stressors may affect thermal and energy homeostasis. This study investigates the effect of EH and GF against heat-induced mouse model. Mice were divided into four groups: saline, saline plus heat, EH plus heat, and GF plus heat treated groups. Heat stress was fixed at 43 °C for 15 min once daily for 3 days. Weight and ear and rectal temperature measurements were made after terminating heat stress. Hypothalamus tissue was collected to evaluate the HSP70, nuclear factor kappa-Β (NF-kB), and interleukin (IL)-1β protein expression levels. EH and GF treatment suppressed the increased body temperature. EH significantly ameliorated heat-induced body weight loss, compared to gypsum. Regulatory effects of EH and GF for body temperature and weight against heat stress were mediated by IL-1β reduction. EH showed significant HSP70 and NF-kB inhibition against heat stress. EH and GF contribute to the inhibition of heat-induced proinflammatory factors and the promotion of hypothalamic homeostasis.

Abstract
Obesity is a medical situation in which excess body fat has gathered because of imbalance between energy intake and energy expenditure. In spite of the fact that the variety of studies are available for obesity treatment and management, its "globesity" still remains a big challenge all over the world. The current systematic review and meta-analysis aimed to evaluate the efficacy, safety, and mechanisms of effective herbal medicines in the management and treatment of obesity and metabolic syndrome in human. We systematically searched all relevant clinical trials via Web of Science, Scopus, PubMed, and the Cochrane database to assess the effects of raw or refined products derived from plants or parts of plants on obesity and metabolic syndrome in overweight and obesity adult subjects. All studies conducted by the end of May 2019 were considered in the systematic review. Data were extracted independently by two experts. The quality assessment was assessed using Consolidated Standards of Reporting Trials checklist. The main outcomes were anthropometric indices and metabolic syndrome components. Pooled effect of herbal medicines on obesity and metabolic syndrome were presented as standardized mean difference (SMD) and 95% confidence interval (CI). A total of 279 relevant clinical trials were included. Herbals containing green tea, Phaseolus vulgaris, Garcinia cambogia, Nigella sativa, puerh tea, Irvingia gabonensis, and Caralluma fimbriata and their active ingredients were found to be effective in the management of obesity and metabolic syndrome. In addition, C. fimbriata, flaxseed, spinach, and fenugreek were able to reduce appetite. Meta-analysis showed that intake of green tea resulted in a significant improvement in weight ([SMD]: -0.75 [-1.18, -0.319]), body mass index ([SMD]: -1.2 [-1.82, -0.57]), waist circumference ([SMD]: -1.71 [-2.66, -0.77]), hip circumference ([SMD]: -0.42 [-1.02, -0.19]), and total cholesterol, ([SMD]: -0.43 [-0.77, -0.09]). In addition, the intake of P. vulgaris and N. sativa resulted in a significant improvement in weight ([SMD]: -0.88, 95 % CI: [-1.13, -0.63]) and triglyceride ([SMD]: -1.67, 95 % CI: [-2.54, -0.79]), respectively. High quality trials are still needed to firmly establish the clinical efficacy of the plants in obesity and metabolic syndrome.

Abstract
OBJECTIVE A retrospective chart review was conducted to explore the effect of Gambisan, a granular extract of novel herbal medicine, for short-term (≤16 weeks) weight loss in adults who are overweight and those with obesity. METHODS Outpatients of Kyung Hee University Korean Medicine Hospital (Seoul, Korea) who took Gambisan and underwent bioelectric impedance analysis were selected (Jan 2011 to Dec 2015); their electronic medical records and clinical charts were retrospectively reviewed. The effectiveness of Gambisan was primarily evaluated by comparing body weight (BW) at baseline and endpoint, using paired t tests; the safety of Gambisan was evaluated on the basis of adverse events (AEs) experienced by patients. RESULTS Two hundred five patients were included in this study. The study population exhibited a significant reduction in BW (73.69 ± 14.49 kg to 69.01 ± 13.20 kg, P < .001) as well as percentage body fat (37.38 ± 5.38% to 34.50 ± 5.83%, P < .001). Moreover, 111 (54.1%) patients achieved modest weight loss (≥5%), while 35 (17.1%) achieved ≥10% weight loss. Furthermore, Gambisan induced significant reduction of BW in all subgroups (body mass index, sex, prescribed duration, and dosage). Among 139 patients with available data, 79 (56.8%) reported loss-of-appetite. In addition, 120 (mostly mild) AEs were reported in 69 (49.6%) patients, and the most frequent AEs were nausea, palpitation, and insomnia. DISCUSSION Despite limitations in interpreting the results of this retrospective medical record review, Gambisan induced statistically and clinically meaningful weight loss with a tolerable level of AEs. Based on the findings of this review, further well-designed clinical trials are warranted.

Abstract
Evodiamine, a bioactive alkaloid from the fruits of the traditional Chinese medicine Evodia rutaecarpa (Juss.) Benth. (Fructus Evodiae, Wuzhuyu), recently gained attention as a dietary supplement for weight loss and optimization of lipid metabolism. In light of its use by patients and consumers, there is an urgent need to elucidate the molecular targets affected by this natural product. Using a novel interactomics approach, the Nematic Protein Organisation Technique (NPOT), we report the identification of ATP-binding cassette transporter A1 (ABCA1), a key membrane transporter contributing to cholesterol efflux (ChE), as a direct binding target of evodiamine. The binding of evodiamine to ABCA1 is confirmed by surface plasmon resonance (SPR) experiments. Examining the functional consequences of ABCA1 binding reveals that evodiamine treatment results in increased ABCA1 stability, elevated cellular ABCA1 protein levels, and ultimately increased ChE from THP-1-derived human macrophages. The protein levels of other relevant cholesterol transporters, ABCG1 and SR-B1, remain unaffected in the presence of evodiamine, and the ABCA1 mRNA level is also not altered.

Abstract
So-Cheong-Ryong-Tang, which is a standardized Korean medicine of the National Health Insurance, is a traditional prescription for the treatment of allergic rhinitis, bronchitis, and bronchial asthma. Simultaneous analysis and development of SCRT is essential for its stability, efficacy, and risk management. In this study, a simple, reliable, and accurate method using ultrahigh-performance liquid chromatography (UPLC) fingerprinting with a diode array detector (DAD) was developed for the simultaneous analysis. The chromatographic separation of the analytes was performed by an ACQUITY UPLC BEH C18 column (1.7 μM, 2.1 × 100 mm, Waters) with a mobile phase of water containing 0.01% (v/v) phosphoric acid and acetonitrile containing 0.01% (v/v) phosphoric acid. The flow rate and detection wavelength were set at 0.4 mL/min and 215, 230, 254, and 280 nm. All calibration curves of the thirteen components showed good linearity (R2 > 0.999). The limit of detection and limit of quantification ranged 0.001-0.360 and 0.004-1.200 µg/mL, respectively. The relative standard deviation (RSD) of intra- and interday was less than 2.60%, and the recoveries were within the range 76.08-103.79% with an RSD value of 0.03-1.50%. The results showed that the developed method was simple, reliable, accurate, sensitive, and precise for the quantification of bioactive components of SCRT.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Gangjihwan (DF), a polyherbal drug composed of Ephedra intermedia Schrenk et C. A. Mayer (Ephedraceae), Lithospermum erythrorhizon Siebold et Zuccarini (Borraginaceae), and Rheum palmatum L. (Polygonaceae), is used to treat obesity in local Korean clinics. The constituents of DF have traditionally been reported to exert anti-obesity and anti-nonalcoholic fatty liver disease (NAFLD) effects. Thus, we investigated the effects of DF on obesity and NAFLD and the underlying mechanisms. MATERIALS AND METHODS DF was extracted with water (DF-FW), 30% ethyl alcohol (DF-GA30), or 70% ethyl alcohol (DF-GA70). The chemical profile of DF was monitored using high performance liquid chromatography (HPLC)-ultraviolet analysis. The effects of DF on indices of obesity and NAFLD in high fat diet (HFD)-fed C57BL/6J mice and HepG2 cells were examined using quantitative real-time polymerase chain reaction, Oil red O staining, hematoxylin-eosin staining, toluidine blue staining, and immunohistochemistry. RESULTS The presence of ephedrine, pseudoephedrine, aloe-emodin, and emodin in DF was determined by 3D chromatography using HPLC. Administration of DF-GA70 to HFD-fed obese mice decreased body weight, epididymal adipose tissue mass, and epididymal adipocyte size. DF-GA70 reduced serum levels of free fatty acids and triglycerides. All three DF extracts lowered serum alanine transaminase levels, hepatic lipid accumulation, and infiltration of macrophages, with the largest effects observed for DF-GA70. DF-GA70 increased mRNA levels of fatty acid oxidation genes and decreased mRNA levels of genes for lipogenesis and inflammation in the liver of obese mice. Treatment of HepG2 cells with a mixture of oleic acid and palmitoleic acid induced significant lipid accumulation, whereas all three DF extracts inhibited lipid accumulation. DF-GA70 also altered the expression of lipolytic and lipogenic genes in HepG2 cells. CONCLUSIONS These results indicate that DF inhibits obesity and obesity-induced severe hepatic steatosis and inflammation without any adverse effects and that these effects may be mediated by regulation of the hepatic expression of lipid metabolism and inflammatory genes. These findings suggest that DF is a safe and efficient anti-obesity and anti-nonalcoholic steatohepatosis drug.

Abstract
Obesity is the state of excessive body fat accumulation and is mainly caused by consuming more calories than are burned through physical activity. Herbal acupuncture (HA), also known as pharmacopuncture, has been increasingly used in clinics of Korean medical to alleviate obesity. This review analyzed four clinical studies and 16 animal studies on the effectiveness of HA as a treatment for obesity. Clinical evidence suggests that various kinds of HA might be beneficial for treating obesity; however, further investigations with well-designed, evidence-based, randomized clinical trials are needed. Animal studies support the idea that HA might be beneficial for the treatment of obesity and provide possible mechanisms, such as anti-inflammation, antioxidation, modulating lipid metabolism and so on, to explain the effect of HA on obesity. This review, based on the evidence collected, suggests that HA could have a beneficial effect for alleviating obesity by modulating inflammation, oxidative stress, lipid metabolism, leptin, and the insulin signal.

Abstract
The development of obesity is related to the regulation of energy intake, energy expenditure, and energy storage in the body. Increasing energy expenditure by inducing lipolysis followed by fat oxidation is one of the alternatives which could help to reverse this increasingly widespread condition. Currently, there is no approved drug targeting on stimulation of energy expenditure available. The use of herbal medicines has become a preferred alternative, supported by the classical consensus on the innocuity of herbal medicine vs synthetic drugs, something that often lacks a scientific basis (ban on Ephedra, for example). The inclusion of functional food in the daily diet has also been promoted although its efficacy requires further investigation. This review summarizes the results of recent work focused on the investigation of edible plant materials targeted at various important pathways related to stimulation of energy expenditure. The aim is to evaluate a number of plants that may be of interest for further studies because of their potential to provide novel lead compounds or functional foods which may be used to combat obesity, but require further studies to evaluate their antiobesity activity in humans.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ephedra sinica (Ma Huang) has been used in traditional Chinese medicine for more than 5000 years for treatment of various conditions, including modern-day obesity. Ephedra has been used as a supplement for weight loss and its effects have been reported. The current study investigated the influence of ephedra on the composition of gut microbiota, and its correlation with weight loss. MATERIALS AND METHODS Clinical data of subjects were measured at pre- and post-intake of ephedra (4g of water extract, roughly equivalent of 24g of crude herb), and analysis of the alteration of gut microbiota was performed simultaneously using 16S rRNA gene based pyrosequencing. RESULTS Body weight (BW), body mass index (BMI), and body fat percentage of subjects were reduced after intake (p<0.05). In correlation analysis, Subdoligranulum, Oscillibacter, and Akkermansia showed an association with changes of BW and BMI (p<0.05). However, the alteration of gut microbiota varied by indigenous microbiota of each subject, and the dissimilarity between microbiota of subjects at pre- and post-intake were different. CONCLUSIONS The influences of gut microbiota are unique according to indigenous microbiota and differences in individual sensitivity to ephedra. Alteration of gut microbiota by ephedra intake showed correlation with loss of BW and BMI.

[PMID: 24384379 DOI: 10.1016/j.jep.2013.12.006] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/07/2013] [Revised: 10/23/2013] [Accepted: 12/03/2013] [Indexed: 06/03/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Evodia, a fruit from Evodia rutaecarpa, has been used in oriental medicine, and since its various pharmaceutical actions, including anti-cancer activity, have become known, evodia has been widely used as a dietary supplement. However, information regarding its toxicity is limited. MATERIALS AND METHODS Evodia fruit from Evodia rutaecarpa (Juss.) Benth. var. officinalis (Dode) Huang (0, 25, 74, 222, 667, and 2000 mg/kg) was administered orally five times per week for 13 weeks. Clinical signs, body weight, food consumption, hematology, serum chemistry, urinalysis, vaginal cytology, sperm morphology, organ weight, and gross and histopathological findings were evaluated. RESULTS Urinary ketone body excretion was detected in males at 667 and 2000 mg/kg and in females at 2000 mg/kg. An increase in absolute/relative liver weight was observed in both sexes at 2000 mg/kg. Although levels of serum alanine aminotransferase, glucose, total cholesterol, and triglycerides were significantly reduced in males and/or females at 200 and/or 667 and 2000 mg/kg, all values were within normal ranges and were considered non-adverse. In addition, no treatment-related differences in body weight, food consumption, hematology, vaginal cytology, sperm morphology, or gross and histopathological examination were detected. CONCLUSIONS The subchronic no-observable-adverse-effect level for evodia fruit powder following oral administration in rats is greater than 2000 mg/kg.

Abstract
The use of herbal medicinal products and supplements has increased tremendously over the past three decades with not less than 80% of people worldwide relying on them for some part of primary healthcare. Although therapies involving these agents have shown promising potential with the efficacy of a good number of herbal products clearly established, many of them remain untested and their use are either poorly monitored or not even monitored at all. The consequence of this is an inadequate knowledge of their mode of action, potential adverse reactions, contraindications, and interactions with existing orthodox pharmaceuticals and functional foods to promote both safe and rational use of these agents. Since safety continues to be a major issue with the use of herbal remedies, it becomes imperative, therefore, that relevant regulatory authorities put in place appropriate measures to protect public health by ensuring that all herbal medicines are safe and of suitable quality. This review discusses toxicity-related issues and major safety concerns arising from the use of herbal medicinal products and also highlights some important challenges associated with effective monitoring of their safety.

Capsaicin and evodiamine ingestion does not augment energy expenditure and fat oxidation at rest or after moderately-intense exercise. Nutr Res 2013; 33:1034-42. [PMID: 24267043 DOI: 10.1016/j.nutres.2013.08.007] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2013] [Revised: 08/12/2013] [Accepted: 08/13/2013] [Indexed: 12/22/2022]
Abstract
Capsaicin and evodiamine are 2 thermogenic agents recognized for their ability to stimulate the sympathetic nervous system. We hypothesized that both capsaicin and evodiamine would be effective at increasing thermogenesis and lipid oxidation during rest and exercise. In a randomized, cross-over design, 11 men ingested 500 mg of cayenne pepper (1.25 mg capsaicin), 500 mg evodiamine, or placebo at rest following 30 minutes of energy expenditure assessment using open-circuit spirometry. Energy expenditure was assessed again prior to commencing approximately 30 minutes of treadmill exercise at 65% peak oxygen consumption. Energy expenditure was assessed for another 30 minutes of the post-exercise period. Heart rate, blood pressure, core temperature, and venous blood samples were obtained 30 minutes before supplement ingestion, 1 hour after supplement ingestion, immediately post-exercise, and 45 minutes post-exercise. Serum markers of lipid oxidation (glycerol, free fatty acids, glucose, epinephrine, and norepinephrine) were determined spectrophotometrically with enzyme-linked immunosorbent assay. Two-way analyses of variance with repeated measures were performed for each dependent variable (P ≤ .05) with Supplement and Test as main effects. Statistical analyses revealed significant main effects for Test for hemodynamics, energy expenditure, serum catecholamines, and markers of fat oxidation immediately post-exercise (P < .05). No significant interactions between Supplement and Test were noted for any criterion variable (P > .05). These results suggest that acute ingestion of 500 mg of cayenne (1.25 mg capsaicin) or evodiamine is not effective at inducing thermogenesis and increasing fat oxidation at rest or during exercise in men.

Evidence-based toxicity evaluation and scheduling of Chinese herbal medicines. JOURNAL OF ETHNOPHARMACOLOGY 2013; 146:40-61. [PMID: 23286904 DOI: 10.1016/j.jep.2012.12.027] [Citation(s) in RCA: 50] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/21/2012] [Revised: 12/19/2012] [Accepted: 12/19/2012] [Indexed: 05/19/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE While there is an increasing number of toxicity report cases and toxicological studies on Chinese herbal medicines, the guidelines for toxicity evaluation and scheduling of Chinese herbal medicines are lacking. AIM The aim of this study was to review the current literature on potentially toxic Chinese herbal medicines, and to develop a scheduling platform which will inform an evidence-based regulatory framework for these medicines in the community. MATERIALS AND METHODS The Australian and Chinese regulations were used as a starting point to compile a list of potentially toxic herbs. Systematic literature searches of botanical and pharmaceutical Latin name, English and Chinese names and suspected toxic chemicals were conducted on Medline, PubMed and Chinese CNKI databases. RESULTS Seventy-four Chinese herbal medicines were identified and five of them were selected for detailed study. Preclinical and clinical data were summarised at six levels. Based on the evaluation criteria, which included risk-benefit analysis, severity of toxic effects and clinical and preclinical data, four regulatory classes were proposed: Prohibited for medicinal usage, which are those with high toxicity and can lead to injury or death, e.g., aristolochia; Restricted for medicinal usage, e.g., aconite, asarum, and ephedra; Required warning label, e.g., coltsfoot; and Over-the-counter herbs for those herbs with a safe toxicity profile. CONCLUSION Chinese herbal medicines should be scheduled based on a set of evaluation criteria, to ensure their safe use and to satisfy the need for access to the herbs. The current Chinese and Australian regulation of Chinese herbal medicines should be updated to restrict the access of some potentially toxic herbs to Chinese medicine practitioners who are qualified through registration.
