Exploring antimicrobial mechanism of essential oil of Amomum villosum Lour through metabolomics based on gas chromatography-mass spectrometry in methicillin-resistant Staphylococcus aureus. Microbiol Res 2020; 242:126608. [PMID: 33068829 DOI: 10.1016/j.micres.2020.126608] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2020] [Revised: 09/14/2020] [Accepted: 09/19/2020] [Indexed: 12/12/2022]
Abstract
Amomum villosum Lour (A. villosum Lour) has medicinal properties and has been widely used in China for many years. Herein we aimed to investigate the antibacterial mechanism and the metabolome variation caused by A. villosum Lour essential oil (EO) in methicillin-resistant Staphylococcus aureus (MRSA). The metabolite profile of MRSA was acquired, and metabolic pathways were assessed for significant alterations caused upon treating bacterial cells with EO, the antibacterial mechanism of EO was further investigated in combination with multiple experiments. Metabolomics analysis revealed that 72 metabolites and 10 pathways were significantly affected. EO specifically disrupted amino acid metabolism and the tricarboxylic acid (TCA) cycle, and also inhibited adenosine triphosphate (ATP) and reactive oxygen species (ROS) synthesis. Furthermore, the activities of pivotal enzymes involved in the TCA cycle were suppressed. Increased ROS levels could decrease the sensitivity of MRSA to EO, improving the survival of EO-treated MRSA cells. Our data indicate that A. villosum Lour EO causes metabolic dysfunction in MRSA, leading to reduced ROS levels, disruption of the TCA cycle, inhibition of ATP synthesis, and suppression of the activities of key enzymes.

Abstract
1. (S)-MP3950 is the (S)-enantiomer of active metabolite of mosapride, which exhibits higher 5-HT4 receptor agonistic effect than mosapride. It shows promise to become a novel drug candidate for the treatment of gastrointestinal motility disorders (GMDs). However, the pharmacokinetic behavior of (S)-MP3950 in the pathological state of GMDs remains unclear. Herein, we investigated the comparative pharmacokinetics of (S)-MP3950 in normal and GMDs rats. 2. The comparative pharmacokinetics of (S)-MP3950 in normal and atropine-induced GMD rats were studied by ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The validated UPLC-MS/MS method was successfully applied to investigate the pharmacokinetic profiles of (S)-MP3950 in normal and atropine-induced GMDs rats. Results showed that comparing to normal rats, Cmax reduced by 73.8%, AUC0-t decreased by 57.6% and AUC0-∞ declined by 56.8% in model rats. Additionally, the elimination half-life (t1/2) and Tmax were prolonged slightly. 3. The pharmacokinetic results demonstrated that the atropine-induced GMDs reduced the absorption of (S)-MP3950. The pharmacokinetics research in the pathological state might provide more useful information for further study of novel gastric motility candidates.

Abstract
The present study is a comparative study on preliminary characterizations and immunostimulatory activities of water-soluble polysaccharides (WSP) from newly hybrid Amomum villosum and its female parent. First, two kinds of WSP were extracted, respectively from the newly hybrid A. villosum called Spring No.1 (WSPH) and its female parent-Longfruit No.2 (WSPP). Then, the differences of preliminary characterizations and immunostimulatory activities in vivo for these two WSP samples were compared. Experimental results showed that WSPH and WSPP had the same monosaccharide composition, and similar ultraviolet and infrared spectra characteristics of polysaccharides, while their immunostimulatory activities, in terms of the weights of spleen and thymus, pinocytic activity and the level of serum hemolysin, showed no significant differences between the groups treated with WSPH and WSPP, respectively. Combined with the findings from other studies in our research group, these results suggested that this novel hybrid could be an acceptable alternative for cultivation of A. villosum.

Abstract
Activity-guided isolation of compounds from the fruits of Amomum xanthioides resulted in the purification of fourteen phenolic compounds, 4-hydroxy-benzaldehyde (1), 3,4-dihydroxybenzaldehyde (2), 3,5-dimethoxy-4-methylbenzaldehyde (3), syringic aldehyde (4), benzoic acid (5), 3,4-dihydroxy benzoic acid (6), vanillic acid (7), 3-hydroxy-2-methoxybenzoic acid (8), o-vanillic acid (9), phenylacetic acid (10), tyrosol (11), pyrocatechol (12), 1,2,4,5-tetramethoxybenzene (13), and 3,3′,5,5′-tetramethoxybiphenyl-4,4′-diol (14). To evaluate the anti-allergic inflammatory activities of these compounds, we examined the inhibitory effects of the isolates (1-14) on histamine release and on the expressions of tumor necrosis factor (TNF)-α and interleukin (IL)–6 genes by using human mast cells. Of the tested compounds, 9, 11, and 13 suppressed histamine release from mast cells, and all isolates attenuated the expressions of the pro-inflammatory cytokines, TNF-α and IL-6 genes in human mast cells.

Abstract
BACKGROUND Many female breast cancer (FBC) patients take Chinese herbal medicine (CHM) and Western medication (WM) concurrently in Taiwan. Despite the possibility of interactions between the CHM and WM mentioned in previous studies, the pattern of these coprescriptions in FBC patients remains unclear. Hence, the aim of the present study is to investigate the utilization of coprescriptions of CHM and WM among the FBC patients in Taiwan. METHODS The study was a cross-sectional survey using the sampled cohort in 2009 obtained from the National Health Insurance Research Database in Taiwan. There were 3,507 FBC patients identified from the registry for catastrophic illness patients. Ambulatory visit records, corresponding prescriptions, and the data of beneficiaries belonging to the FBC patients were further extracted. A total of 1,086 FBC patients used CHM at least once. CHM and WM prescribed within any overlapping duration were defined as coprescriptions. RESULTS There were 868 (80.0%) patients simultaneously receiving CHM and WM. A total of 4,927 CHM prescriptions and 6,358 WM prescriptions were prescribed concurrently. Among these coprescriptions, the most frequently used CHM was jia-wei-xiao-yao-san (21.2%), and the most frequently coprescribed WM was acetaminophen (38.9%), followed by tamoxifen (25.5%). There were 346 patients using systemic adjuvant therapy and CHM concurrently. The most commonly coprescribed CHM with chemotherapy, endocrine therapy, and trastuzumab was xiang-sha-liu-jun-zi-tang, jia-wei-xiao-yao-san, and zhi-gan-cao-tang, respectively. CONCLUSION The combined use of CHM with WM is prevalent. The main purpose of combining CHM with systemic cancer treatment is to alleviate the treatment-related adverse effects. However, the combination may result in the potential risk of drug-herb interactions. Further clinical studies are needed to evaluate the efficacy and safety of the CHM and WM coprescriptions for FBC patients.

Abstract
IMPORTANCE OF THE FIELD the global increase in the popularity of alternative medicines has raised renewed concerns regarding herb-drug interactions. These interactions are especially important for drugs with narrow therapeutic indices and may either be pharmacodynamic or pharmacokinetic in nature. AREAS COVERED IN THIS REVIEW pharmacokinetic interactions which may exist between herbs and drugs, and the mechanisms of these interactions with appropriate examples based on primary and secondary data in publications are discussed. The mechanisms covered include those that affect oral drug absorption (e.g., modulation of efflux and uptake transporters, complex formation, gastrointestinal motility and pH) and drug biotransformation (e.g., inhibition or induction of enzymes). WHAT THE READER WILL GAIN knowledge on the mechanisms of herb-drug pharmacokinetic interactions supported by an extended list of these types of interactions for quick reference. A critical evaluation of certain herb-drug pharmacokinetic interactions reported in the scientific literature. TAKE HOME MESSAGE as the incidence and severity of herb-drug pharmacokinetic interactions increase due to a worldwide rise in the use of herbal preparations, more clinical data regarding herb-drug pharmacokinetic interactions are needed to make informed decisions regarding patient safety.

Abstract
The protective effect of Amomi semen extract (ASE) on alloxan-induced pancreatic beta-cell damage was investigated in HIT T-15 cells, a Syrian hamster pancreatic beta-cell line. Alloxan caused pancreatic beta-cell damage through the generation of reactive oxygen species (ROS), the elevation of cytosolic free Ca2+, DNA fragmentation and the decrease of cellular NAD+ and ATP levels. All these effects of alloxan were significantly prevented by pretreatment with a water-soluble extract of Amomi semen. Pretreatment with ASE in pancreatic islets isolated from mice, also significantly abolished the inhibition of glucose-stimulated insulin secretion by alloxan. The results of this study provide evidence that ASE may have a protective activity on alloxan-induced beta-cell damage, and that the protective effect is primarily due to the inhibition of ROS generation by alloxan.

Abstract
Dendritic cells (DCs) have a major role in regulating immune responses, including tumor immunity and peripheral tolerance. In the present study, we identified novel functions of herbal medicines in DCs by screening 99 herbal medicines, most of which are among the 210 Chinese medicines approved by the Ministry of Health, Labour, and Welfare, Japan. Ethanol extracts were prepared, and a murine epidermal-derived Langerhans cell line, XS106, was used to screen the 99 extracts by analyzing major histocompatibility complex (MHC) class II expression. Amomi Semen (amomum seed), Polyporus (polyporus sclerotium), and Plantaginis Semen (plantago seed) potently activated XS106 and were selected for further analysis. The effects of these extracts on bone marrow-derived DCs (BM-DCs) generated in vitro were then analyzed using surface phenotype (MHC class II, CD80, and CD86) and interleukin (IL)-12p70 production as indicators. BM-DCs treated with Amomi Semen extract exhibited activated phenotypes and secreted IL-12p70. The activation level was similar to that induced by lipopolysaccharides. Finally, an E.G7-OVA tumor model (E.L4-OVA transfectant) was used to examine the anti-tumor effects of Amomi Semen extract. Vaccination of mice with a subcutaneous injection of BM-DCs treated with Amomi Semen extract and OVA peptide significantly inhibited the growth of tumor cells and prolonged survival time compared to controls. Furthermore, therapeutic effects were observed on established tumors. The inhibition rates for both the prophylactic and therapeutic protocols were comparable to those of lipopolysaccharides. These results indicate that Amomi Semen extract potently activate DCs and is potentially useful for DC vaccination.

Abstract
This study was to investigate the effects of water-soluble carbohydrate concentrate (WSCC) prepared from Chinese jujube ( Zizyphus jujuba) on different intestinal and fecal indices in a hamster model. WSCC contained carbohydrates (771 g kg(-1) of WSCC) including glucose, fructose, pectin polysaccharide, and hemicellulose. The administration of WSCC (5.0 and 15 g kg(-1) of diet) effectively ( P<0.05) shortened gastrointestinal transit time (by 34.2-57.3%), reduced cecal ammonia (by 58.1-60.3%), elevated total short-chain fatty acid concentrations in cecum (3-4-fold), increased fecal moisture (147-170%), reduced daily fecal ammonia output (by 31.9-75.8%), and decreased the activities of beta-D-glucuronidase (by 73.0-73.8%), beta-D-glucosidase (by 58.2-85.7%), mucinase (by 46.2-72.6%), and urease (by 31.9-48.7%) in feces. This study suggested that adequate consumption of jujube WSCC (at least 5.0 g kg(-1) of diet or 40 mg day(-1)) might exert favorable effects on improving the gastrointestinal milieu and reducing the exposure of intestinal mucosa to toxic ammonia and other detrimental compounds.

Abstract
The dose effects of pectic polysaccharide-rich extract from the food spice cardamom (Amomum villosum Lour.) on intestinal environment were investigated. The results showed that pectic polysaccharides and hemicellulose were the major polysaccharides in the cardamom extract. The administration of cardamom extract (0.5 and 1.5 g/100 g diet) effectively (p < 0.05) shortened hamster gastrointestinal transit time by approximately 58%, increased fecal moisture contents (148-174%), increased SCFA concentrations in hindgut (4.0- to 7.8-fold), decreased the activities of beta-D-glucuronidase (by 71.4-85.7%), beta-D-glucosidase (by 24.3-51.5%), mucinase (by 63.6-72.7%), and urease (by 88.8-90.4%) in feces, and reduced the production of toxic ammonia (by 16.1-64.5%). These findings suggested that the consumption of cardamom extract (at least 0.5 g/100 g diet or 40 mg/day) might exert a favorable effect on improving the gastrointestinal milieu, and also provide a clue to substantiate its traditional therapeutic uses and dosage for intestinal health improvement.

Abstract
The effect of an aqueous extract of the dried immature fruit of Poncirus trifoliata Raf. (Rutaceae) (PF-W) on gastrointestinal (GI) motor function was investigated by measuring the intestinal transit rate (ITR) of Evans blue in rats and mice with experimental GI motility dysfunctions (GMDs). GMD was induced by appropriate surgery or by the administration of acetic acid, atropine, L-DOPA, or morphine to the animals. The ITR in these GMD animals was significantly retarded compared to normal animals. The retardation, however, was significantly inhibited by the intragastric administration of PF-W (0.1-1g/kg) in a dose dependent manner for all GMD models except for L-DOPA-induced GMD. The above results suggest that PF-W has the potential for development as a prokinetic agent that may prevent or alleviate GMD in human patients.

Abstract
Hepatocellular carcinoma is one of the most common causes of death from cancer in Taiwan. Treatments for this disease include surgical resection, transcatheter arterial embolization, chemoembolization and systemic chemotherapy. Without treatment, the prognosis of hepatocellular carcinoma is poor, and mortality continues to be significant even in patients with small tumors detected during follow-up. For patients in Taiwan with advanced hepatocellular carcinoma, traditional herbal medicine is frequently used. However, neither the overall prevalence of this therapy nor its efficacy has been studied systematically. Spontaneous regression of cancer, although rare, may occur, but the mechanism leading to regression is still far from understood. Here, we report a case of hepatocellular carcinoma with complete regression after taking herbal medicine. We cannot be certain how significant the herbal preparation was in the regression of the hepatocellular carcinoma, but the regression of the tumor provides us a reason and hope for further research.

[PMID: 15099855 DOI: 10.1016/j.jep.2004.02.003] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/25/2003] [Revised: 10/23/2003] [Accepted: 02/03/2004] [Indexed: 05/24/2023]
Abstract
Amomi Semen has been used as a folk remedy for the treatment of diabetes in Korea. The aim of this study was to examine whether it had an enhancing effect on glucose uptake, an essential process of insulin action. Its aqueous ethanolic extract significantly stimulated glucose uptake in 3T3-L1 adipocytes at the concentration of 0.5 mg/ml. The extract significantly potentiated insulin-stimulated glucose uptake with a dose-dependent manner at a concentration range from 0.02 to 0.5 mg/ml. The results suggest that the antidiabetic action of Amomi may be mediated through the stimulation of glucose uptake and the potentiation of insulin action.
