Selective effect of 2',6'-dihydroxy-4'-methoxychalcone isolated from Piper aduncum on Leishmania amazonensis. (1/302)

2',6'-Dihydroxy-4'-methoxychalcone (DMC) was purified from the dichloromethane extract of Piper aduncum inflorescences. DMC showed significant activity in vitro against promastigotes and intracellular amastigotes of Leishmania amazonensis, with 50% effective doses of 0.5 and 24 micrograms/ml, respectively. Its inhibitory effect on amastigotes is apparently a direct effect on the parasites and is not due to activation of the nitrogen oxidative metabolism of macrophages, since the production of nitric oxide by both unstimulated and recombinant gamma interferon-stimulated macrophages was decreased rather than increased with DMC. The phagocytic activity of macrophages was functioning normally even with DMC concentrations as high as 80 micrograms/ml, as seen by electron microscopy and by the uptake of fluorescein isothiocyanate-labeled beads. Ultrastructural studies also showed that in the presence of DMC the mitochondria of promastigotes were enlarged and disorganized. Despite destruction of intracellular amastigotes, no disarrangement of macrophage organelles were observed, even at 80 micrograms of DMC/ml. These observations suggest that DMC is selectively toxic to the parasites. Its simple structure may well enable it to serve as a new lead compound for the synthesis of novel antileishmanial drugs.  (+info)

Epoxide hydrolases regulate epoxyeicosatrienoic acid incorporation into coronary endothelial phospholipids. (3/302)

Cytochrome P-450-derived epoxyeicosatrienoic acids (EETs) are avidly incorporated into and released from endothelial phospholipids, a process that results in potentiation of endothelium-dependent relaxation. EETs are also rapidly converted by epoxide hydrolases to dihydroxyeicosatrienoic acid (DHETs), which are incorporated into phospholipids to a lesser extent than EETs. We hypothesized that epoxide hydrolases functionally regulate EET incorporation into endothelial phospholipids. Porcine coronary artery endothelial cells were treated with an epoxide hydrolase inhibitor, 4-phenylchalcone oxide (4-PCO, 20 micromol/l), before being incubated with (3)H-labeled 14,15-EET (14,15-[(3)H]EET). 4-PCO blocked conversion of 14,15-[(3)H]EET to 14,15-[(3)H]DHET and doubled the amount of radiolabeled products incorporated into cell lipids, with >80% contained in phospholipids. Moreover, pretreatment with 4-PCO before incubation with 14,15-[(3)H]EET enhanced A-23187-induced release of radiolabeled products into the medium. In contrast, 4-PCO did not alter uptake, distribution, or release of [(3)H]arachidonic acid. In porcine coronary arteries, 4-PCO augmented 14,15-EET-induced potentiation of endothelium-dependent relaxation to bradykinin. These data suggest that epoxide hydrolases may play a role in regulating EET incorporation into phospholipids, thereby modulating endothelial function in the coronary vasculature.  (+info)

2'-hydroxychalcone inhibits nuclear factor-kappaB and blocks tumor necrosis factor-alpha- and lipopolysaccharide-induced adhesion of neutrophils to human umbilical vein endothelial cells. (4/302)

Inhibition of expression of cell adhesion molecules (CAM), including intercellular CAM-1 (ICAM-1), vascular CAM-1 (VCAM-1), and E-selectin, has been shown to be important in controlling various inflammatory diseases. The cell adhesion proteins are induced by various inflammatory cytokines, such as tumor necrosis factor-alpha, interleukin-1, and bacterial lipopolysaccharide. The induction process primarily takes place at the level of transcription, where nuclear factor-kappaB (NF-kappaB) plays a major role. We demonstrate here that 2'-hydroxychalcone inhibits the adhesion of peripheral neutrophils to the endothelial cell monolayers by inhibiting the expression of ICAM-1, VCAM-1, and E-selectin in a concentration-dependent manner. The inhibition by 2'-hydroxychalcone is reversible. 2'-hydroxychalcone inhibits the induction of steady-state transcript levels of ICAM-1, VCAM-1, and E-selectin by tumor necrosis factor-alpha as determined by reverse transcription-polymerase chain reaction, and therefore it may interfere with the transcription of their genes. Because NF-kappaB is a major transcription factor involved in CAM expression, we studied its status in the 2'-hydroxychalcone treated cells. We demonstrate that 2'-hydroxychalcone inhibits the activation of NF-kappaB. These results have implications for using NF-kappaB inhibitors for the treatment of various inflammatory diseases.  (+info)

Neohesperidin dihydrochalcone is not a taste enhancer in aqueous sucrose solutions. (5/302)

Neohesperidin dihydrochalcone (NHDC) is an intensive sweetener, obtained by alkaline hydrogenation of neohesperidin. In this investigation a supposed taste enhancing effect of this substance was tested. A three-step procedure was used. In the first experiment, using a pool of 31 subjects, NHDC and sucrose detection thresholds were measured. In the second experiment, psychophysical functions for both tastants were determined. Then, 15 participants closest to the group threshold who, in addition, had produced monotonic psychophysical taste functions were selected to participate in the next two experiments. In the third experiment, taste enhancement was tested. Three psychophysical sucrose functions were constructed, one with a near-threshold amount of NHDC added to each of seven sucrose concentrations, one with a near-threshold amount of sucrose added (control 1) and one without any addition (control 2). No difference was found between the NHDC-enriched sucrose function and the sucrose-enriched sucrose function. Finally, in experiment 4, differential threshold functions were constructed with either NHDC or sucrose added. Neither the overall shape of the functions nor a comparison of the points of subjective equality showed enhancement. It was concluded that weak NHDC does not enhance the taste of aqueous sucrose solutions.  (+info)

Flavonoids inhibit cell growth and induce apoptosis in B16 melanoma 4A5 cells. (6/302)

We investigated the growth inhibitory activity of several flavonoids, including apigenin, luteolin, kaempherol, quercetin, butein, isoliquiritigenin, naringenin, genistein, and daizein against B16 mouse melanoma 4A5 cells. Isoliquiritigenin and butein, belonging to the chalcone group, markedly suppressed the growth of B16 melanoma cells and induced cell death. The other flavonoids tested showed little growth inhibitory activity and scarcely caused cell death. In cells treated with isoliquiritigenin or butein, condensation of nuclei and fragmentation of nuclear DNA, which are typical phenomena of apoptosis, were observed by Hoechst 33258 staining and by agarose gel electrophoresis of DNA. Flowcytometric analysis showed that isoliquiritigenin and butein increased the proportion of hypodiploid cells in the population of B16 melanoma cells. These results demonstrate that isoliquiritigenin and butein inhibit cell proliferation and induce apoptosis in B16 melanoma cells. Extracellular glucose decreased the proportion of hypodiploid cells that appeared as a result of isoliquiritigenin treatment. p53 was not detected in cells treated with either of these chalcones, however, protein of the Bcl-2 family were detected. The level of expression of Bax in cells treated with either of these chalcones was markedly elevated and the level of Bcl-XL decreased slightly. Isoliquiritigenin did not affect Bcl-2 expression, but butein down-regulated Bcl-2 expression. From these results, it seems that the pathway by which the chalcones induce apoptosis may be independent of p53 and dependent on proteins of the Bcl-2 family. It was supposed that isoliquiritigenin induces apoptosis in B16 cells by a mechanism involving inhibition of glucose transmembrane transport and promotion of Bax expression. On the other hand, it was suggested that butein induces apoptosis via down-regulation of Bcl-2 expression and promotion of Bax expression. This mechanism differs from the isoliquiritigenin induction pathway.  (+info)

PROP (6-n-Propylthiouracil) tasting and sensory responses to caffeine,sucrose, neohesperidin dihydrochalcone and chocolate. (7/302)

The genetically determined ability to taste 6-n-propylthiouracil (PROP) has been linked with lowered acceptance of some bitter foods. Fifty-four women, aged 18-30 years, tasted and rated PROP-impregnated filter paper and seven solutions of PROP. Summed bitterness intensity ratings for PROP solutions determined PROP taster status. Respondents also tasted five sucrose and seven caffeine solutions, as well as seven solutions each of caffeine and PROP that had been sweetened with 0.3 mmol/l neohesperidin dihydrochalcone (NHDC). Respondents also rated three kinds of chocolate using 9-point category scales. PROP tasters rated caffeine solutions as more bitter than did non-tasters and liked them less. PROP tasters did not rate either sucrose or NHDC as more sweet. The addition of NHDC to PROP and caffeine solutions suppressed bitterness intensity more effectively for tasters than for non-tasters and improved hedonic ratings among both groups. PROP tasters and non-tasters showed the same hedonic response to sweetened caffeine solutions and did not differ in their sensory responses to chocolate. Genetic taste markers may have only a minor impact on the consumption of such foods as sweetened coffee or chocolate.  (+info)

Dibenzoylmethane modulates aryl hydrocarbon receptor function and expression of cytochromes P50 1A1, 1A2, and 1B1. (8/302)

The phytochemical dibenzoylmethane (DBM) has been shown to prevent polycyclic aromatic hydrocarbon (PAH)-induced tumorigenesis in rodents. However, the biochemical basis of this activity is unclear. We have therefore investigated the effects of DBM on the activity and expression of carcinogen-activating enzymes, the cytochromes P450 (CYP) 1A1, 1A2, and 1B1. Oral administration of DBM to female Sprague Dawley rats inhibited the increase in hepatic enzyme activity and mRNA levels of CYP1A1, 1A2, and 1B1 caused by the PAH 7,12-dimethylbenz[a]anthracene (DMBA). However, DBM administration alone caused an increase in both activity and expression in the liver, albeit to levels much lower than that induced by DMBA. To characterize the molecular mechanisms involved in this dual action of DBM, we examined the effects of DBM in vitro. In HepG2 human hepatoma cells, DBM inhibited DMBA- and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)-induced enzyme activity and CYP1A1, 1A2, and 1B1 mRNA levels, whereas DBM itself induced activity and mRNA expression. Modulation of CYP1A1 expression by DBM occurred at the transcriptional level, as transient transfection assays demonstrated. Because the transcription of CYP1A1 is regulated by the aryl hydrocarbon receptor (AhR), we investigated the effect of DBM on AhR activation. DBM inhibited TCCD-induced DNA-binding of the AhR to the xenobiotic-responsive element (XRE) of CYP1A1 as measured by electrophoretic mobility shift assay. These data suggest that the chemopreventive activity of DBM results from its ability to affect Phase 1 enzyme expression by modulation of AhR function.  (+info)

Chalcone or (E)-1,3-diphenyl-2-propene-1-one scaffold has gained considerable scientific interest in medicinal chemistry owing to its simple chemistry, ease in synthesizing a variety of derivatives and exhibiting a broad range of promising pharmacological activities by modulating several molecular targets. A number of natural and (semi-) synthetic chalcone derivatives have demonstrated admirable anti-inflammatory activity due to their inhibitory potential against various therapeutic targets like Cyclooxygenase (COX), Lipooxygenase (LOX), Interleukins (IL), Prostaglandins (PGs), Nitric Oxide Synthase (NOS), Leukotriene D4 (LTD4), Nuclear Factor-κB (NF- κB), Intracellular Cell Adhesion Molecule-1 (ICAM-1), Vascular Cell Adhesion Molecule-1 (VCAM-1), Monocyte Chemoattractant Protein-1 (MCP-1) and TLR4/MD-2, etc ...
Quantum mechanical calculations at B3LYP/6-31G** level of theory were employed to obtain energy (E), ionization potential (IP), bond dissociation enthalpy (O-H BDE) and stabilization energies (DEiso) in order to infer the scavenging activity of dihydrochalcones (DHC) and structurally related compounds. Spin density calculations were also performed for the proposed antioxidant activity mechanism of 2,4,6-trihydroxyacetophenone (2,4,6-THA). The unpaired electron formed by the hydrogen abstraction from the phenolic hydroxyl group of 2,4,6-THA is localized on the phenolic oxygen at 2, 6, and 4 positions, the C3 and C6 carbon atoms at ortho positions, and the C5 carbon atom at para position. The lowest phenolic oxygen contribution corresponded to the highest scavenging activity value. It was found that antioxidant activity depends on the presence of a hydroxyl at the C2 and C4 positions and that there is a correlation between IP and O-H BDE and peroxynitrite scavenging activity and lipid peroxidation.

Nuclear factor (NF)-κB is a mediator of inflammatory diseases and cancer and has been shown to induce resistance to various chemotherapeutic agents. This transcription factor is implicated in immunity, anti-apoptosis, proliferation, and activation of more than 550 target genes involved in tumor promotion, angiogenesis, and metastasis. The canonical NF-κB pathway is characterized by a cascade leading to activation of the functional heterodimer p50/p65. After stimulation by tumor necrosis factor (TNF)α, activation of the Iκ kinase (IKK) complex leads to phosphorylation of the inhibitory subunit IκBα followed by subsequent proteasomal degradation. As a result, NF-κB p50/p65 translocates to the nucleus and transcription is activated.. Besides NF-κB signaling, other pathways are strongly linked to inflammation processes, including extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinases (JNK), and p38 signal transduction pathways. The ERK1/2-mediated signaling pathway is ...

Flavonoids are a major class of plant secondary metabolites that serves a multitude of functions including pigments and antioxidant activity. Flavonoids are synthesized from phenylpropanoid derivatives by condensation with malonyl-CoA. For example, condensation of p-coumaroyl-CoA (C6-C3) with three malonyl-CoA (C3) molecules results in naringenin chalcone with a diphenylpropane (C6-C3-C6) unit, which is converted to naringenin with the flavone (2-phenylchromen-4-one) backbone by conjugate ring closure. These and further modifications yield a variety of structural forms including chalcones, flavanones, dihyroflavonols, and flavans, anthocyanins, flavones and flavonols, and isoflavonoids ...

Authors: OFENTSE MAZIMBA Abstract: 6$H$-Benzo[$c$]chromen-6-ones serve as core structures of secondary metabolites and are of considerable pharmacological importance. Natural sources produce limited quantities, hence the need for synthetic procedures for 6$H$-benzo[$c$]chromen-6-ones, which are herein reviewed. The literature describes protocols such as the Suzuki coupling reactions for the synthesis of biaryl, which then undergoes lactonization, reactions of 3-formylcoumarin (chromenones) with 1,3-bis(silylenol ethers), radical mediated cyclization of arylbenzoates, metal or base catalyzed cyclization of phenyl-2-halobenzoates and 2-halobenzyloxyphenols, and benzoic acid coupling with benzoquinone using electrophilic metal-based catalyst. The efficient and simple procedures are those involving the reactions of Michael acceptor (chromenones and chalcones) with 1,3- and 1,5-dicarbonyl compounds. Keywords: 6$H$-Benzo[$c$]chromen-6-ones, benzopyranone, biaryls, Suzuki coupling, Michael addition, ...

Flavonoids are synthesized by the phenylpropanoid metabolic pathway in which the amino acid phenylalanine is used to produce 4-coumaroyl-CoA. This can be combined with malonyl-CoA to yield the true backbone of flavonoids, a group of compounds called chalcones, which contain two phenyl rings. Conjugate ring-closure of chalcones results in the familiar form of flavonoids, the three-ringed structure of a flavone. The metabolic pathway continues through a series of enzymatic modifications to yield flavanones → dihydroflavonols → anthocyanins. Along this pathway, many products can be formed, including the flavonols, flavan-3-ols, proanthocyanidins (tannins) and a host of other various polyphenolics. Flavanoids can possess chiral carbons. Methods of analysis should take this element into account especially regarding bioactivity or enzyme stereospecificity. The biosynthesis of flavonoids involves several enzymes. Anthocyanidin reductase Chalcone isomerase Dihydrokaempferol 4-reductase Flavone ...

In recent years, intraarticular inflammation has been recognized to contribute to the symptoms and progression of osteoarthritis (OA). Inflammation in OA is associated with increased levels of catabolic enzymes and inflammatory mediators such as nitric oxide (NO), interleukin-1ß (IL-1ß) and tumor necrosis factor-α (TNF-α). Chondrocytes and infiltrating inflammatory cells, neurtrophils and macrophages, participate in the production of these catabolic mediators [1]. Extract from the heartwood of Caesalpinia sappan and its active components were reported to have antioxidative, antibacterial and anti-inflammatory effects [2]. The present study was designed to investigate whether ethanolic extract of C. sappan possesses anti-inflammatory activities in an in vitro model of joint inflammation comprising primary human osteoarthritic chondrocytes and differentiated THP-1 macrophage cells.

Activity-guided fractionation of a hop extract led to the isolation of XN and of its cyclization product, the flavanone IX, as potential cancer chemopreventive agents. Although hop constituents have been previously reported to modulate carcinogen metabolism and to act by cytotoxic/cytostatic mechanisms, a demonstration of chemopreventive activity in animal models and of potential value for chemoprevention in humans is missing.. In vivo efficacy of selected chalcones as chemopreventive agents against pulmonary and oral carcinogenesis has been demonstrated in a limited number of studies (49, 50). Interestingly, the chalcone structure of XN is modified by substitution with a prenyl side chain. Prenylation is an important posttranslational modification of proteins, e.g., the Ras oncoprotein, and results in higher lipophilicity and targeting of the modified protein to the cell membrane (51). It is tempting to speculate that likewise, prenylation might also influence solubility, cellular uptake, and ...
There are six major subgroups found in most higher plants: the chalcones, flavones, flavonols, flavandiols, anthocyanins, and condensed tannins (proanthocyanidins); a seventh group, the aurones, are not ubiquitos. Isoflavonoids are found mostly in legumes but also in a small number of non-legume plants and another specialized form of flavonoids, the phlobaphenes (monomers: 3-deoxyanthocyanins), have been detected in only a few species so far. Stilbenes, closely related to flavonoids, are synthesized by yet another group of unrelated species ...

A compound found in liquorice can have adverse effects on follicle growth and sex hormone production in mouse ovaries.. Jodie Flaws, professor in comparative biosciences from the University of Illinois and one of the lead authors on the study, argued that although the study did not demonstrate these effects in humans, it is likely that they could have serious implications for fertility.. The study, published in Reproductive Toxicology, was the first to study the effects of a liquorice compound, isoliquiritigenin, on the ovary. Professor Flaws team exposed mouse ovarian follicles to isoliquiritigenin in vitro, and found that it led to reduced expression of genes involved in sex hormone production. For example, production of aromatase, an enzyme which converts testosterone to oestrogen, was reduced by 50 percent.. Professor Flaws said: In general, when you start to have lower hormone levels, you could start to have problems with reproduction. And because oestrogen is also important for healthy ...

Isoflavonoid signal molecules from soybean (Glycine max (L.) Merr.) seed and root exudate induce the transcription of nodulation (nod) genes in Bradyrhizobium japonicum. In this study, a new compound with symbiotic activity was isolated from soybean root exudate. The isolated 2,4,4-trihydroxychalcone (isoliquiritigenin) is characterized by its strong inducing activity for the nod genes of B. japonicum. These genes are already induced at concentrations 1 order of magnitude below those required of the previously described isoflavonoid inducers genistein and daidzein. Isoliquiritigenin is also a potent inducer of glyceollin resistance in B. japonicum, which renders this bacterium insensitive to potentially bactericidal concentrations of glyceollin, the phytoalexin of G. max. No chemotactic effect of isoliquiritigenin was observed. The highly efficient induction of nod genes and glyceollin resistance by isoliquiritigenin suggests the ecological significance of this compound, although it is not a ...

Introduction. Chagas disease, caused by the protozoan parasite Trypanosoma cruzi, is a major cause of illness, morbidity, long-term disability, and death in Latin America. It is estimated that about 16-18 million people are infected and other 100 million are at risk of infection, with more than 50,000 deaths each year. In spite of the alarming health, economic, and social consequences of this parasitic infection, the limited existing drug therapy (nifurtimox and benznidazole) suffers from a combination of drawbacks including poor efficacy, and serious side effects. Therefore, there is an urgent need for new chemotherapeutic agents with novel mechanisms of action.1-3. Enzymes are extremely attractive targets for small molecule drug intervention in human diseases.1,2 One important drug target is the major cysteine protease from T. cruzi, cruzain (EC 3.4.22.51). This enzyme is implicated in several vital processes of the parasite, playing a pivotal role during the infection of host cells, ...

Several epidemiological studies have investigated the association between the dietary flavonoid intake and gastric cancer (GC) risk; however, the results remain inconclusive. Investigating the relationship between the different classes of flavonoids and the histological types and origin of GC can be of interest to the research community. We used data from a population-based multi-case control study (MCC-Spain) obtained from 12 different regions of Spain. 2700 controls and 329 GC cases were included in this study. Odds ratios (ORs) were calculated using the mixed effects logistic regression considering quartiles of flavonoid intakes and log2. Flavonoid intake was associated with a lower GC risk (ORlog2 = 0.76; 95% CI = 0.65-0.89; ORq4vsq1 = 0.60; 95%CI = 0.40-0.89; ptrend = 0.007). Inverse and statistically significant associations were observed with anthocyanidins, chalcones, dihydroflavonols and flavan-3-ols. The isoflavanoid intake was positively associated with higher cancer risk, but without ...

Chalcone and its derivates are group reported to show promising anticancer activity. These compounds are precursor of flavonoids and isoflavonoids abundant in crops. Previous research suggested that Chalcone and its derivatives have anticancer activity in several cancer cells. Chalcone natural and synthetic showed strong antiproliferative effect on ovarian cancer cells and in gastric cancer cells HGC-27 (Achanta, et al., 2006). Hydroxyl Chalcone and isoliquiritigenin showed a strong inhibitor on skin carcinogenesis in vivo. Some research indicates that Chalcone also act as a chemoprevention agent, capable of inhibit carcinogenesis induced by chemical agents through increasing levels of reduced glutathione. However, the exact mechanism of the compound Chalcone in tumor cells is still being revealed. It has been proposed that isoliquiritigenin inhibit the proliferation of lung cancer cells A549 by stopping the cell cycle phase G2/M and induce p21 expression. Research on HepG2 hepatocellular ...

Because of the unsatisfactory treatment options for breast cancer (BC), there is a need to develop novel therapeutic approaches for this malignancy. One such strategy is chemotherapy using non-toxic dietary substances and botanical products. Studies have shown that Panduratin A (PA) possesses many health benefits, including anti-inflammatory, anti-bacterial, anti-oxidant and anticancer activities. In the present study, we provide evidence that PA treatment of MCF-7 BC cells resulted in a time- and dosedependent inhibition of cell growth with an IC50 of 15 μM and no to little effect on normal human MCF-10A breast cells. To define the mechanism of these anti-proliferative effects of PA, we determined its effect critical molecular events known to regulate the cell cycle and apoptotic machinery. Immunofluorescence and flow cytometric analysis of Annexin V-FITC staining provided evidence for the induction of apoptosis. PA treatment of BC cells resulted in increased activity/expression of ...

Tumor-induced angiogenesis is essential for invasive growth and hematogenous metastasis of adenoid cystic carcinoma (ACC), a highly aggressive neoplasm mostly occurring in salivary glands. Previous studies have indicated that strategies directed against angiogenesis will help develop new therapeutics for ACC. The Chinese folk medicine licorice has been used for years as a natural remedy for angiogenesis-related diseases. Here we examined the effects of isoliquiritigenin (ISL), a flavonoid isolated from licorice, on the growth and viability of ACC cells, and observed a concentration-dependent (0-20 μM) inhibition of cell growth without cell death at 24 h. In a further mimic co-culture study, ISL effectively suppressed the ability of ACC cells to induce in vitro proliferation, migration and tube formation of human endothelial hybridoma (EAhy926) cells as well as ex vivo and in vivo angiogenesis, whereas it exerted no effect on EAhy926 cells when added directly or in the presence of vascular ...

According to the research team, both of these licorice root extract components could play a role in preventing and treating tooth decay and periodontal disease. Dried licorice root is commonly used in Chinese traditional medicine to treat digestive and respiratory conditions. Modern research has found evidence that licorice root extract can be effective against development of cavities and gum infections.. Among the more interesting studies are those using licorice lollipops to fight tooth decay. In research conducted at the University of California, Los Angeles (UCLA), for example, investigators found that sugar-free lollipops containing a licorice root extract killed S. mutans and other cavity-causing bacteria. Do all of these findings mean you should start eating licorice candy? The authors pointed out that the licorice in candy in the United States has been replaced with anise oil. You should consult your dentist or other healthcare provider before taking true licorice root in any ...

PMID: 31493544 de Moura Escobar SJ, Simone M, de Oliveira Ribeiro CA, Martinez GR, Winnischofer SMB, Witting PK, Rocha MEM (2019) Toxicol In Vitro Abstract: Neuroblastoma is an aggressive form of cancer with high mortality. Hydroxychalcones have received considerable attention because of their cytotoxic activities on cancer cells. However, the effect of the 4-hydroxychalcone on neuroblastoma cells is unknown. The aim of the present study was to characterize the cytotoxicity of 4HC to neuroblastoma and the importance of mitochondrial effects in its action mechanism using an in vitro model of SH-SY5Y cells. Incubation of cultured SHSY5Y cells with 10-60 μM 4HC (24 h) decreased cell confluency, cellular metabolic activity and depleted intracellular ATP relative to the vehicle-treated control. The mechanism of 4HC-induced cell toxicity likely involves mitochondria dysfunctional as judged by inhibition of mitochondrial respiration, depolarization of mitochondria membrane potential and intracellular ...

Wearable kinematic sensors can be used to study head injury biomechanics based on kinematics and, more recently, based on tissue strain metrics using kinematics-driven brain models. These sensors require in-situ calibration and there is currently no data conveying wearable ability to estimate tissue strain. We simulated head impact (n = 871) to a 50th percentile Hybrid III (H-III) head wearing a hockey helmet instrumented with wearable GForceTracker (GFT) sensors measuring linear acceleration and angular velocity. A GFT was also fixed within the H-III head to establish a lower boundary on systematic errors. We quantified GFT errors relative to H-III measures based on peak kinematics and cumulative strain damage measure (CSDM). The smallest mean errors were 12% (peak resultant linear acceleration) and 15% (peak resultant angular velocity) for the GFT within the H-III. Errors for GFTs on the helmet were on average 54% (peak resultant linear acceleration) and 21% (peak resultant angular velocity). ...

Glycyrrhizin is a natural sweet substance from the licorice root plant that gives the typical licorice flavor. The amount of glycyrrhizin used in various licorice products, confectionery and beverages varies considerably.. Glycyrrhizin may give negative health effects. Several Finnish studies show long-term adverse effects on the child as a result of high consumption of licorice during pregnancy. The food and health authorities in Finland recommend that pregnant women should avoid large consumption of licorice confectionery. Likewise, the Norwegian Food Safety Authority advises pregnant women against eating large amounts of licorice.. In order to describe the dietary recommendation further and to have a scientific basis for assessing if other measures are necessary, the Norwegian Food Safety Authority requests VKM to identify and characterize potential adverse effects to the fetus and long-term effects to the child that can result from maternal consumption of glycyrrhizin from licorice..

Colorectal cancer is one of the most common lethal cancer types worldwide. In recent years, widespread and large-scale studies have been done on medicinal plants for anti-cancer effects, including Glycyrrhiza glabra. The aim of this study was to evaluate the effects of an ethanol extract Glycyrrhiza glabra on the expression of HSP90, growth and apoptosis in the HT-29 colon cancer cell line. HT-29 cells were treated with different concentrations of extract (50,100,150, and 200 μg/ml). For evaluation of cell proliferation and apoptosis, we used MTT assay and flow cytometry technique, respectively. RT-PCR was also carried out to evaluate the expression levels of HSP90 genes. Results showed that Glycyrrhiza glabra inhibited proliferation of the HT-29 cell line at a concentration of 200 μg/ml and this was confirmed by the highest rate of cell death as measured by trypan blue and MTT assays. RT-PCR results showed down-regulation of HSP90 gene expression which implied an ability of Glycyrrhiza glabra to
BACKGROUND: Protozoan parasites of the genus Trypanosoma cause disease in a wide range of mammalian hosts. Trypanosoma brucei brucei, transmitted by tsetse fly to cattle, causes a disease (Nagana) of great economic importance in parts of Africa. T. b. brucei also serves as a model for related Trypanosoma species, which cause human sleeping sickness. MATERIALS AND METHODS: Chalcone and acyl hydrazide derivatives are known to retard the growth of Plasmodium falciparum in vitro and inhibit the malarial cysteine proteinase, falcipain. We tested the effects of these compounds on the growth of bloodstream forms of T. b. brucei in cell culture and in a murine trypanosomiasis model, and investigated their ability to inhibit trypanopain-Tb, the major cysteine proteinase of T. b. brucei. RESULTS: Several related chalcones, acyl hydrazides, and amides killed cultured bloodstream forms of T. b. brucei, with the most effective compound reducing parasite numbers by 50% relative to control populations at a
Imagine everything happened merely because of a mistake when (around 1750) the French clergyman Pierre dIncarville brought to Paris from faraway China a stock of seeds that he thought were those of the prized lacquer tree (Rhus verniciflua) but were instead ailanthus seeds (Ailanthus altissima, sin. A. glandulosa). Thus begins one of the most important biological invasions of the plant world in the modern times. This neophyte was valued in Europe for its beautiful appearance (it can reach over 20-25 m in height with an elegant straight habit, and a trunk diameter of more than 1 m; its foliage is pleasing to the eye and is reminiscent of walnut and ash trees). Its hardiness is incomparable (it has no acclimatization problems as regards climate or edaphic factors). It is easy to cultivate and grows exceptionally fast. It is perfect for beautifying streets and parks, reinforcing slopes, and colonizing difficult, unstable terrain. One episode that contributed to its dissemination was when the ...
