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)

Improvement of in vitro and in vivo antileishmanial activities of 2', 6'-dihydroxy-4'-methoxychalcone by entrapment in poly(D,L-lactide) nanoparticles. (2/302)

The inhibition of intracellular Leishmania amazonensis growth by 2', 6'-dihydroxy-4'-methoxychalcone (DMC) isolated from Piper aduncum was further enhanced after encapsulation of DMC in polymeric nanoparticles. Encapsulated DMC also showed increased antileishmanial activity in infected BALB/c mice, as evidenced by significantly smaller lesions and fewer parasites in the lesions.  (+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)

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.

A series of B-ring, halo-substituted chalcones and azachalcones were synthesized to evaluate and compare their anti-inflammatory activity. Mouse BALB/c macrophage RAW 264.7 were pre-treated with 10 μg/mL of each compound for one hour before induction of inflammation by lipopolysaccharide (1 μg/mL) for 6 h. Some halo-chalcones and -azachalcones suppressed expression of pro-inflammatory factors toll-like receptor 4 (TLR4), IκB-α, transcription factor p65, interleukine 1β (IL-1β), IL-6, tumor necrosis factor α (TNF-α), and cyclooxygenase 2 (COX-2). The present results showed that the synthetic halo-azachalcones exhibited more significant inhibition than halo-chalcones. Therefore, the nitrogen atom in this series of azachalcones must play a more crucial role than the corresponding C-2 hydroxyl group of chalcones in biological activity. Our findings will lay the background for the future development of anti-inflammatory nutraceuticals ...

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.

Isoliquiritigenin (ISL) is an emerging natural flavonoid found in the roots of licorice, exhibits antioxidant, anti-cancer, anti-inflammatory, anti-allergic, cardioprotective, hepatoprotective and neuroprotective properties. However, the effect of ISL in embryonic development is yet to be elucidated, and the mechanisms underlying its target-organ toxicity and harmful side effects are still unclear. In the present study, we employed zebrafish embryos to study the developmental toxicity effect of ISL and its underlying mechanisms. Zebrafish embryos upon treatment with either vehicle control (0.1% DMSO) or ISL solutions for 4-96 h post fertilization (hpf) showed that ISL exposure instigated severe developmental toxicity in heart, liver, and nervous system. Mortality and morphological abnormalities were also observed. High concentrations of ISL exposure resulted in abnormal phenotypes and embryonic malformations including pericardial edema, swim bladder defects, yolk retention, curved body shape and ...

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.

Computer-aided Design of Chalcone Derivatives as Lead Compounds Targeting Acetylcholinesterase - E-JURNALComputer-aided Design of Chalcone Derivatives as Lead Compounds Targeting Acetylcholinesterase - E-JURNAL
Abstract: One of well-established biological activities for chalcone derivatives is as acetylcholinesterase inhibitors, which can be developed for the therapy of Alzheimers disease. Assisted byretrospectively validated structure-based virtual screening (SBVS) protocol to identify potent acetylcholinesterase inhibitors, 80chalcone derivatives were designed and virtually screened. The F-measure value as the parameter of the predictive ability of the SBVS protocol developed in the research presented in this article was 0.413, which was considerably better than the original SBVS protocol (F-measure = 0.226). Among the screened chalcone derivatives two were selected as potential lead compounds to designpotent inhibitors for acetylcholinesterase: 3-[4-(benzyloxy)-3-methoxyphenyl]-1-(4-hydroxy-3-methoxyphenyl)prop-2-en-1-one(3k) and 3-[4-(benzyloxy)-3-methoxyphenyl]-1-(4-hydroxyphenyl)prop-2-en-1-one (4k). ...

HPLC of flavanones and chalcones in different species and clones of Salix. - Semantic ScholarHPLC of flavanones and chalcones in different species and clones of Salix. - Semantic Scholar
The SPE-HPLC method was developed to determine an isosalipurposide (5) and its derivative, 6-O-p-coumaroyl ester (6) in the bark of eight taxa (I-VIII) belonging to three species of the genus Salix and originating from a natural habitat or cultivated for pharmaceutical purposes. The chalcones were separated by HPLC under gradient elution with the concentration of ACN increasing from 20% to 50% in 0.1% aqueous H3PO, (tG 15 min). The content of both compounds was determined by an external standardization with the use of isoliquiritigenin (7) as a reference substance - a commercially available chalcone, and also isosalipurposide (5) and its derivative, 6-O-p-coumaroyl ester (6). The latter compound was isolated from the bark of Salix daphnoides (IV) by a CC and semi-preparative HPLC and its structure was elucidated by MS and NMR spectra. It was stated that 6-O-p-coumaroylisosalipurposide (6), in addition to isosalipurposide (5), is a characteristic flavonoid for the S. daphnoides species. Moreover, the

Rhizomes of Boesenbergia pandurata (Roxb.) Schlecht have been reported to contain active compounds with anticancer properties. This research was carried out to examine anti-proliferative and apoptotic induction against HeLa and Vero cells-line. Dried powder of B. pandurata rhizomes was extracted by a maceration method using 90% ethanol. Cytotoxic assays to determine IC50 and anti-proliferative effects were carried out by MTT methods. Observation of apoptosis was achieved with double staining using acridine orange and ethidium bromide. The results showed that ethanolic extract of B. pandurata was more cytotoxic against HeLa cells (IC50 of 60 μg/ mL) than Vero cells (IC50 of 125 μg/mL). The extract had higher anti-proliferative activity as well as apoptotic induction in HeLa than Vero cells. Therefore, it was concluded that the ethanolic extract of B. pandurata had anti-proliferative as well as apoptosis induction activity dependent on the cell type.

Butein (3,4,2,4-tetrahydroxychalone), a plant polyphenol, is a major biologically active component of the stems of Rhus verniciflua Stokes. It has long been used as a food additive in Korea and as an herbal medicine throughout Asia. Recently, butein has been shown to suppress the functions of fibroblasts. Because fibroblasts are believed to play an important role in promoting the growth of breast cancer cells, we investigated the ability of butein to inhibit the clonogenic growth of small numbers of breast cancer cells co-cultured with fibroblasts in vitro. We first measured the clonogenic growth of small numbers of the UACC-812 human breast cancer cell line co-cultured on monolayers of serum-activated, human fibroblasts in the presence of butein (2 μg/mL) or various other modulators of fibroblast function (troglitazone-1 μg/mL; GW9662-1 μM; meloxican-1 μM; and 3,4 dehydroproline-10 μg/mL). In a subsequent experiment, we measured the dose-response effect on the clonogenic growth of UACC-812

Second Harmonic Generation in Some Donor-Acceptor Substituted Chalcone DerivativesSecond Harmonic Generation in Some Donor-Acceptor Substituted Chalcone Derivatives
cy [3]. The presence of strong electron donating groups, the parallel head to tail alignment, inter and intra molecular hydrogen bonds are the reasons to get high SHG efficiency. The one of the parameter which controls the molecular orientation and the stability of the crystal structure are the hydrogen bond interactions [17-18]. For efficient SHG the molecules arranged in parallel or zigzag head-to-tail fashion with molecules interlinked by strong hydrogen bond interactions are essential [19]. The D (donor)-H… X (acceptor), π… π type interactions are believed to contribute significantly to the macroscopic NLO properties of organic crystals in the exited state [20]. These hydrogen bond interactions are the virtual roots to extend the molecular charge transfer into supramolecular realm and there by extending the conjugation throughout the interaction length of the crystal. Such an increase in the conjugation via hydrogen bond interacttions leads to the very high SHG efficiency of molecular ...

Flavonoid biosynthesis - WikipediaFlavonoid biosynthesis - Wikipedia
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 ...

A Convergent Approach for the Synthesis of New Pyrazolyl Bipyridinyl Substituted Coumarin Derivatives as AntimicrobialsA Convergent Approach for the Synthesis of New Pyrazolyl Bipyridinyl Substituted Coumarin Derivatives as Antimicrobials
Some new 3-[3-(1-phenyl-3-aryl-1H-pyrazol-4-yl) acryloyl] coumarins 3a-f were synthesized (coumarin chalcones) by the condensation of various 3-acetyl coumarins 1 and appropriate 1-phenyl-3-aryl-1H-pyrazole-4-carbaldehyde 2. These coumarin chalcones 3a-f were then employed for the synthesis of pyrazolyl bipyridinyl substituted coumarins 7a-f, 8a-f, and 9a-f under Krohnkes reaction condition. The characterization of all the synthesized compounds was carried out by elemental analysis, IR, 1H-NMR, 13C-NMR, DEPT-135 and mass spectral analysis. In addition to that, in vitro antimicrobial competency of the title compounds was assessed against selected pathogens. Compounds 3b, 3e, 7b, 8b, 8c and 9b exhibited excellent antimicrobial activity and said to be the most proficient members of the series.

Intracerebral hemorrhage (ICH) induces potently oxidative stress responses and inflammatory processes. Isoliquiritigenin (ILG) is a flavonoid with a chalcone structure and can activate nuclear factor erythroid-2 related factor 2 (Nrf2)-mediated antioxidant system, negatively regulate nuclear factor-κB (NF-κB) and nod-like receptor family, pyrin domain-containing 3 (NLRP3) inflammasome pathways, but its role and potential molecular mechanisms in the pathology following ICH remain unclear. The present study aimed to explore the effects of ILG after ICH and underlying mechanisms. ICH model was induced by collagenase IV (0.2 U in 1 μl sterile normal saline) in male Sprague-Dawley rats weighing 280-320 g. Different doses of ILG (10, 20, or 40 mg/kg) was administrated intraperitoneally at 30 min, 12 h, 24 h, and 48 h after modeling, respectively. Rats were intracerebroventricularly administrated with control scramble small interfering RNA (siRNA) or Nrf2 siRNA at 24 h before ICH induction, and after 24 h,

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 ...

BioNews - Liquorice could lower female fertilityBioNews - Liquorice could lower female fertility
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 ...

Proanthocyanidin - WikipediaProanthocyanidin - Wikipedia
Condensed tannins may be characterised by a number of techniques including depolymerisation, asymmetric flow field flow fractionation or small-angle X-ray scattering. DMACA is a dye that is particularly useful for localization of proanthocyanidin compounds in plant histology. The use of the reagent results in blue staining.[17] It can also be used to titrate proanthocyanidins. Proanthocyanidins from field beans (Vicia faba)[18] or barley[19] have been estimated using the vanillin-HCl method, resulting in a red color of the test in the presence of catechins or proanthocyanidins. Proanthocyanidins can be titrated using the Procyanidolic Index (also called the Bates-Smith Assay). It is a testing method that measures the change in color when the product is mixed with certain chemicals. The greater the color changes, the higher the PCOs content is. However, the Procyanidolic Index is a relative value that can measure well over 100. Unfortunately, a Procyanidolic Index of 95 was erroneously taken to ...
