Aim of the study
This study was conducted to elucidate the molecular mechanisms of SH21B, a traditional Korean herbal medicine commonly used for the treatment of obesity.Materials and methods
3T3-L1 preadipocytes were differentiated into adipocytes in the presence or absence of SH21B. Changes in mRNA or protein levels were analyzed using microarray, real-time polymerase chain reaction and western blotting analyses. Small interference (si)RNA transfection experiments were conducted to elucidate the essential role of β-catenin.Results
Microarray analyses showed that components of the WNT/β-catenin pathway including β-catenin, cyclin D1 and dishevelled 2 were up-regulated more than two-fold as a result of SH21B treatment during adipogenesis, which were confirmed by real-time PCR and western blotting. Modulation of the WNT/β-catenin pathway by SH21B resulted in the nuclear accumulation of β-catenin. Both intracellular lipid droplet formation and expressions of adipogenic genes including PPARγ, C/EBPα, FABP4 and LPL, which were inhibited by SH21B, were significantly recovered by β-catenin siRNA transfection.Conclusions
SH21B modulates components of the WNT/β-catenin pathway during adipogenesis, and β-catenin plays a crucial role in the anti-adipogenic mechanism of SH21B. 相似文献3.

The shrub Phyllanthus piscatorum Kunth (Euphorbiaceae) is cultivated by various ethnic groups of the Amazon because of its piscicidal properties. During ethnobotanical fieldwork among the Yanomam? Amerindians in Venezuela we observed that Phyllanthus piscatorum was exclusively cultivated and used by the women. Aerial parts of this herbaceous shrub are employed as fish poison and medicine to treat wounds and fungal infections. In addition, the leaves are used as tobacco substitute. Ethnobotanical data regarding the context of the use of this plant are presented. To validate ethnobotanical information related to its medicinal indications, antimicrobial, and antiprotozoal properties of water, methanol (MeOH) and dichloromethane (DCM) extracts were studied. No activity against Gram-positive bacterial strains but significant activity against the fungi Aspergillus fumigatus, Aspergillus flavus and the yeast Candida albicans were found. All extracts showed weak in vitro activity against Plasmodium falciparum and Trypanosoma brucei rhodesiense. The extracts were further investigated for cytotoxic effects in an in vitro test system with leukemia Jurkat T, HeLa, and human peripheral mononuclear blood cells (PBMCs). During the first 48 h the extracts did not exhibit any cytotoxicity. After 72 h the DCM extract potently inhibited viability of HeLa cells. Although in several communities along the upper Orinoco the cultivation and use of Phyllanthus piscatorum is being lost because of the ongoing acculturation, the traditional medicinal use of Phyllanthus piscatorum might provide an effective and cheap remedy against dermatological diseases linked with Candida albicans infections. 相似文献

Aims of the study
Extracts of Schisandra chinensis have been used as an anti-fatigue and tonic agent. Because chronic fatigue syndrome is related to inflammatory and oxidative stress, we assessed whether Schisandra chinensis has anti-inflammatory constituents and studied the effect of a novel α-cubebenoate isolated from Schisandra chinensis.Materials and methods
α-Cubebenoate was isolated from an extract of Schisandra chinensis fruits. The inductions of inducible nitric oxide synthase (iNOS) and cyclooxygenase 2 (COX-2) by lipopolysaccharide (LPS) were quantified by RT-PCR and Western blotting in mouse peritoneal macrophages. Nitric oxide (NO) and prostaglandin E2 (PGE2) were also measured in the media by Griess reagent and EIA method. A mouse model of LPS-induced peritonitis was used to test the in vivo efficacy of α-cubebenoate.Results
α-Cubebenoate (5–10 μg/ml) inhibited the inductions of iNOS and COX-2 in mouse peritoneal macrophages at the mRNA and protein levels. LPS-induced productions of NO and PGE2 were inhibited by α-cubebenoate (5–10 μg/ml). In addition, α-cubebenoate inhibited the LPS-induced activation of JNK, but not those of ERK and p38 MAPK in mouse peritoneal macrophages. Furthermore, in the LPS-induced in vivo peritonitis model, α-cubebenoate (1 mg/kg) strongly inhibited the accumulation of polymorph nuclear lymphocytes in the peritoneal cavity.Conclusion
α-Cubebenoate inhibited LPS-induced expression of iNOS and COX-2 in a concentration-dependent manner, thereby suppressing productions of NO and PGE2 in vitro in peritoneal macrophages. α-Cubebenoate also inhibited LPS-induced accumulation of polymorph nuclear lymphocytes in LPS-induced peritonitis model in vivo. α-Cubebenoate may act as an anti-fatigue constituent of Schisandra chinensis through anti-inflammation and could be of therapeutic use as a treatment for inflammatory diseases. 相似文献7.

Five new farnesyl-α-nitropyrroles, nitropyrrolins A-E (1-5), were isolated from the saline culture of the marine actinomycete strain CNQ-509. This strain belongs to the "MAR4" group of marine actinomycetes, which have been demonstrated to be a rich source of hybrid isoprenoid secondary metabolites. The structures of the nitropyrrolins are composed of α-nitropyrroles with functionalized farnesyl groups at the C-4 position. These compounds are the first examples of naturally occurring terpenyl-α-nitropyrroles. Chemical modifications, including one-step acetonide formation from an epoxide, and application of the modified Mosher method provided the full stereostructures and absolute configurations of these compounds. Several of the nitropyrrolins, nitropyrrolin D in particular, are cytotoxic toward HCT-116 human colon carcinoma cells, but show weak to little antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA). 相似文献

Myocardial infarction (MI) is one of the diseases with high fatality rate. Berberine (BBR) is a monomer compound with various biological functions. And some studies have confirmed that BBR plays an important role in alleviating cardiomyocyte injury after MI. However, the specific mechanism is unclear. In this study, we induced a model of MI by ligation of the left anterior descending coronary artery and we surprisingly found that BBR significantly improved ventricular remodeling, with a minor inflammatory and oxidative stress injury, and stronger angiogenesis. Moreover, BBR inhibited the secretion of Wnt5a/β-catenin pathway in macrophages after MI, thus promoting the differentiation of macrophages into M2 type. In summary, BBR effectively improved cardiac function of mice after MI, and the potential protective mechanism was associated with the regulation of inflammatory responses and the inhibition of macrophage Wnt5a/β-catenin pathway in the infarcted heart tissues. Importantly, these findings supported BBR as an effective cardioprotective drug after MI. 相似文献

Qingre Zaoshi Liangxue Fang (QRZSLXF) is a Chinese medicinal herb recipe that is commonly prescribed for the treatment of ulcerative colitis. It includes 5 quality assured herbs: Sophora flavescens Aiton., Baphicacanthus cusia (Nees) Bremek., Bletilla striata Rchb.f., Glycyrrhiza uralensis Fisch. and Coptis chinensis Franch. The main phytochemical ingredient of QRZSLXF includes ammothamnine, sophocarpidine, liquiritin, berberine and indirubin. QRZSLXF has been clinically proven for use in the treatment of ulcerative colitis for over twenty years. In the past ten years, research has confirmed the therapeutic effect of QRZSLXF in ulcerative colitis and partially revealed its mechanism of action. Here, we further reveal the therapeutic mechanism of QRZSLXF in ulcerative colitis. To investigate the role of the DOR-β-arrestin1-Bcl-2 signal transduction pathway in ulcerative colitis and to determine the effects of QRZSLXF on this signal transduction pathway.Materials and methods
Eighty-four Sprague-Dawley rats were randomly divided into six groups: normal control group, model group, mesalazine group, and QRZSLXF high-dose, medium-dose group and low-dose groups (n=14). Experimental colitis was induced by trinitrobenzenesulfonic acid (TNBS) in each group, except the normal control group. After modeling, bloody stool, mental state and diarrhea were observed and recorded. Two rats were randomly selected from the model groups adfnd sacrificed on day 3 to observe pathological changes in the colon tissue by microscopy. The rats in the QRZSLXF-treated groups received intramuscular injections of different concentrations of QRZSLXF for 15 days. The rats in the mesalazine group were treated with mesalazine solution (0.5 g/kg/day) by gastric lavage for 15 days. The rats in the normal control group and the model group were treated with 3 mL water by gastric lavage for 15 days. On the 16th day, after fasting for 24 h, the remaining rats were sacrificed and their colon tissues were used to detect the mRNA and protein expressions of DOR, β-arrestin1 and Bcl-2 by Real-time PCR and immunohistochemistry, respectively. Histological changes in the colon tissues were also examined.Results and conclusions
The expressions of DOR, β-arrestin1 and Bcl-2 were significantly different among the four groups. The expressions of DOR, β-arrestin1 and Bcl-2 protein and mRNA were significantly increased in the model group compared with the other groups (P<0.05). In contrast to the model group, the expressions of DOR, β-arrestin1 and Bcl-2 were significantly decreased in the mesalazine group and the groups that received different doses of QRZSLXF (P<0.05), and there were no statistically significant differences among the mesalazine and QRZSLXF-treated groups (P>0.05). This study indicates that the DOR-beta-arrestin1-Bcl-2 signal transduction pathway may participate in the pathologic course of ulcerative colitis. Moreover, QRZSLXF could attenuate ulcerative colitis by regulating the DOR-β-arrestin1-Bcl-2 signal transduction pathway. 相似文献13.

A green pigment, viridaphin A? glucoside (1), was isolated from the green aphid Megoura crassicauda. One- and two-dimensional NMR spectrometric analyses of 1 and its aglycone established the structure as an octacyclic compound. Viridaphin A? glucoside exhibited cytotoxicity against HL-60 human tumor cells with an IC?? of 23 μM and antibacterial activity against Bacillus subtilis NBRC 3134 with a minimum inhibitory concentration of 10.0 μg/mL. These results suggested that aphid pigments may protect aphids from invasive species, including viruses and bacteria. 相似文献

Terminalia chebula has an esteemed origin in Indian mythology; its fruits are used to treat many diseases such as digestive, diabetes, colic pain, chronic cough, sore throat, asthma, etc.Aim of the study
The water or ethanolic extracts of the fruits were reported to have anti-oxidant, anti-inflammatory, anti-cancer and radio-protector properties. The present study is to isolate and identify the compounds that inhibit COX and 5-LOX, the key enzymes involved in inflammation and carcinogenesis.Materials and methods
The ethanolic extract of the fruits was fractionated by RP-HPLC and fractions were tested for enzyme inhibition activity against COX and 5-LOX. One of the fractionated compounds showed potent dual inhibition against COX and 5-LOX. It was identified as chebulagic acid by LC–MS, NMR and IR analyses. The chebulagic acid was also tested for anti-proliferative activity.Results
Chebulagic acid showed potent COX–LOX dual inhibition activity with IC50 values of 15 ± 0.288, 0.92 ± 0.011 and 2.1 ± 0.057 μM for COX-1, COX-2 and 5-LOX respectively. It also showed anti-proliferative activity against HCT-15, COLO-205, MDA-MB-231, DU-145 and K562 cell lines. Further mechanistic studies on COLO-205 cells revealed induction of apoptosis by chebulagic acid.Conclusions
Chebulagic acid, a COX-2 and 5-LOX dual inhibitor isolated from the fruits of Terminalia chebula, induces apoptosis in COLO-205 cells. 相似文献16.

Nelumbo nucifera Gaertn. leaves have been used as medicinal herbs in the past 1300 years, specifically utilized to cure hyperlipidemia, hyperglycemia, and obesity. It has been recorded in the most famous medicinal book in China for more than 400 years. The present study aims to identify the potential therapeutic activities of the flavonoids isolated from Nelumbo nucifera leaves.Materials and methods
Nelumbo nucifera leaf flavonoids (NLF) were tested for the inhibition of lipase, α-glucosidase, and α-amylase activities in vitro. A single dose of NLF was administered by oral gavage in mice for acute toxicity. Wistar rats with high-fat diet-induced hyperlipidemia and two other animal models were used to evaluate the hypolipidemic effects of NLF.Results
Our in vitro biochemistry tests revealed that the NLF showed high inhibitory activity against porcine pancreatic lipase, α-amylase, and α-glucosidase with IC50 values of 0.38±0.022, 2.20±0.18, and 1.86±0.018 mg/mL, respectively. Furthermore, the NLF significantly lowered the lipid components, such as the total cholesterol, triglycerides, low-density lipoprotein cholesterol, and malondialdehyde, in various established in vivo systems and raised the high-density lipoprotein cholesterol. Moreover, the NLF alleviated high-fat diet-induced lipid accumulation in the liver.Conclusions
The results demonstrate that NLFs can effectively ameliorate hyperlipidemia and inhibit the key enzymes related to type 2 diabetes mellitus. Our findings may provide new pharmacological basis for the treatment of hyperlipidemia, hyperglycemia, and obesity using NLFs. 相似文献17.
Previous experience of acupuncture is believed to affect people's expectation of future treatments. Therefore, subjects who have had acupuncture are generally excluded from sham-controlled acupuncture clinical trials. However, this assumption has not been proven, but just accepted because of the lack of evidence to the contrary. To investigate the difference in frequency and intensity of acupuncture sensation between subjects who have had acupuncture and those who have not, 36 acupuncture-experienced subjects were invited to take part in the study. After informed consent was obtained, participants were asked to complete the acupuncture sensation scale (ASS) according to what they expected needling to feel like. The needling was done at the left Hegu (LI 4) point and consisted of insertion, stimulation for 30 seconds and removal. After needling, the subjects were asked to complete the same ASS according to what they actually experienced. Adverse events were monitored. The frequency of each sensation expected and experienced, as well as acupuncture sensation scores were compared. More than 60% of the subjects expected to feel sensations of penetrating (87.6% to 100%), aching (71.2% to 95.5%), tingling (87.6% to 100%), pricking (79.7% to 99.2%) and throbbing (64.2% to 91.4%). In fact, the subjects experienced sharp (60.9% to 89.1%), intense (60.9% to 89.1%), radiating (71.2% to 95.5%) and heavy (74.8% to 97.4%) sensations just as much. The subjects expected more hurting (p = 0.001), tingling (p < 0.001), pricking (p = 0.010), stinging (p = 0.012), burning (p = 0.001) and pulsing (p = 0.009) than they experienced, while more heaviness (p = 0.011) was experienced than expected. The same outcome measures were also compared between experienced and naive groups. Apart from the fact that the acupuncture-experienced participants expected to feel pricking (p = 0.030) and stinging (p = 0.002), and experienced hurting (p = 0.022) and stinging (p = 0.028) significantly less than those who had not had acupuncture before, there was no significant difference between first time and experienced subjects. The results indicate that previous experience does not affect the people's expectation and does not hinder people from experiencing Deqi. In addition, a constellation of Deqi-related acupuncture-specific sensations is more than just a general pain intensity dimension, which requires a biochemical and physiological exploration. 相似文献

Can the aggregation be a new approach for understanding the mechanism of Traditional Chinese Medicine? 总被引:2,自引:0,他引:2
"Frequent hitter" phenomenon emerged in the high-throughput screening; one of the most common mechanisms behind artifactual inhibition is that some organic molecules formed large colloid-like aggregates which are able to sequester and thereby inhibit enzymes. To investigate the situation in Traditional Chinese Medicine (TCM), 60 medicinal herbs and 24 Chinese herbal formulae were detected by dynamic light scattering (DLS), and aggregates were observed in all the 84 solution mixtures. The aggregates of two Chinese herbal formulae, 'Xue-Fu-Zhu-Yu Tang' (XF) and 'Jing-Guan Tang' (JG), were not only able to survive in the gastro-intestinal environment, but also had the ability to pass through the monolayer of the Caco-2 cell. The activities of XF and JG against three cardiovascular targets were also aggregates-related. Based on these findings, a new possible mechanism of the action of Chinese medicine was proposed. 相似文献
