Substrate specificity of catechol oxidase from Lycopus europaeus and characterization of the bioproducts of enzymic caffeic acid oxidation. (1/401)The substrate specificity of catechol oxidase from Lycopus europaeus towards phenols is examined. The enzyme catalyzes the oxidation of o-diphenols to o-quinones without hydroxylating monophenols, the additional activity of tyrosinase. Substrates containing a -COOH group are inhibitors for catechol oxidase. The products of enzymic oxidation of caffeic acid were analyzed and isolated by HPLC with diode array detection. The neolignans of the 2,3-dihydro-1,4-benzodioxin type (3, 6-8), 6,7-dihydroxy-1-(3,4-dihydroxyphenyl)-2,3-dicarboxy-1,2-dihydro naphthaline (1) 6,7-dihydroxy-1-(3,4-dihydroxyphenyl)-3-carboxynaphthaline (5) and 2,6-bis-(3',4'-dihydroxyphenyl)-1-carboxy-3-oxacyclo-(3,0)-pent an-2-on-1-ene (4) were formed. A reaction mechanism for the formation of (1, 4 and 5) is discussed. (+info)
Dehydrodicaffeic acid dilactone, an inhibitor of catechol-O-methyl transferase. (2/401)In the screening of catechol-O-methyltransferase inhibitors, three compounds were isolated from the culture filtrate of a mushroom, Inonotus sp. One was 3,4-dihydroxycinnamic acid (caffeic acid) which had been reported as an inhibitor of this enzyme. The others were the dextrorotatory 2,6-bis-(3',4'-dihydroxyphenyl)-3,7-dioxabicyclo-[3,3,0]-octane 4,8-dione (dehydrodicaffeic acid dilactone) andits antipode. These new compounds inhibited both dopamine beta-hydroxylase and dopa decarboxylase and showed hypotensive activity in the SH rat. (+info)
Inhibitory effects of caffeic acid phenethyl ester on the activity and expression of cyclooxygenase-2 in human oral epithelial cells and in a rat model of inflammation. (3/401)We investigated the mechanisms by which caffeic acid phenethyl ester (CAPE), a phenolic antioxidant, inhibited the stimulation of prostaglandin (PG) synthesis in cultured human oral epithelial cells and in an animal model of acute inflammation. Treatment of cells with CAPE (2.5 microg/ml) suppressed phorbol ester (12-O-tetradecanoylphorbol-13-acetate; TPA) and calcium ionophore (A23187)-mediated induction of PGE2 synthesis. This relatively low concentration of CAPE did not affect amounts of cyclooxygenase (COX) enzymes. CAPE nonselectively inhibited the activities of baculovirus-expressed hCOX-1 and hCOX-2 enzymes. TPA- and A23187-stimulated release of arachidonic acid from membrane phospholipids was also suppressed by CAPE (4-8 microg/ml). Higher concentrations of CAPE (10-20 microg/ml) suppressed the induction of COX-2 mRNA and protein mediated by TPA. Transient transfections using human COX-2 promoter deletion constructs were performed; the effects of TPA and CAPE were localized to a 124-bp region of the COX-2 promoter. In the rat carrageenan air pouch model of inflammation, CAPE (10-100 mg/kg) caused dose-dependent suppression of PG synthesis. Amounts of COX-2 in the pouch were markedly suppressed by 100 mg/kg CAPE but were unaffected by indomethacin. These data are important for understanding the anticancer and anti-inflammatory properties of CAPE. (+info)
Genetic analysis of a chromosomal region containing vanA and vanB, genes required for conversion of either ferulate or vanillate to protocatechuate in Acinetobacter. (4/401)VanA and VanB form an oxygenative demethylase that converts vanillate to protocatechuate in microorganisms. Ferulate, an abundant phytochemical, had been shown to be metabolized through a vanillate intermediate in several Pseudomonas isolates, and biochemical evidence had indicated that vanillate also is an intermediate in ferulate catabolism by Acinetobacter. Genetic evidence supporting this conclusion was obtained by characterization of mutant Acinetobacter strains blocked in catabolism of both ferulate and vanillate. Cloned Acinetobacter vanA and vanB were shown to be members of a chromosomal segment remote from a supraoperonic cluster containing other genes required for completion of the catabolism of ferulate and its structural analogs, caffeate and coumarate, through protocatechuate. The nucleotide sequence of DNA containing vanA and vanB demonstrated the presence of genes that, on the basis of nucleotide sequence similarity, appeared to be associated with transport of aromatic compounds, metabolism of such compounds, or iron scavenging. Spontaneous deletion of 100 kb of DNA containing this segment does not impede the growth of cells with simple carbon sources other than vanillate or ferulate. Additional spontaneous mutations blocking vanA and vanB expression were shown to be mediated by IS1236, including insertion of the newly discovered composite transposon Tn5613. On the whole, vanA and vanB appear to be located within a nonessential genetic region that exhibits considerable genetic malleability in Acinetobacter. The overall organization of genes neighboring Acinetobacter vanA and vanB, including a putative transcriptional regulatory gene that is convergently transcribed and overlaps vanB, is conserved in Pseudomonas aeruginosa but has undergone radical rearrangement in other Pseudomonas species.

The rabbit lens epithelial cell line N/N1003A requires 12-lipoxygenase activity for DNA synthesis in response to EGF. (5/401)PURPOSE: Cultured rat lenses and primary human lens epithelial cells (HLECs) express12-lipoxygenase (12-LOX) and require a 12-LOX metabolite of arachidonic acid for growth in response to EGF and insulin. This study seeks to identify an established cell line with these characteristics. METHODS: Immunoblotting was used to screen eight lens epithelial cell lines for 12-LOX expression: the human line, HLE-B3; mouse lines alphaTN4, 17EM15, 21EM15, and MLE6, and rabbit lines N/N1003A, LEP2 and B3. DNA synthesis was measured as incorporation of 3H-thymidine into DNA. Expression of c-fos mRNA was detected by RT-PCR. The involvement of 12-lipoxygenase metabolites was determined using the lipoxygenase inhibitors baicalein, cinnamyl 3,4-dihydroxy-alpha-cyanocinnamate (CDC), or nordihydroguiairetic acid (NDGA). RESULTS: 12-LOX was detected only in the rabbit lines N/N1003A, LEP2 and B3. N/N1003A cells were chosen for further study. 12-LOX inhibitors blocked DNA synthesis in response to EGF with or without insulin. Inhibition of EGF-stimulated DNA synthesis was reversed by 0.3 microM to 3 microM 12(S)hydroxyeicosatetraenoic acid (HETE), but not by equivalent concentrations of 5(S)HETE, 8(S)HETE, 15(S)HETE, or 12(R)HETE. Baicalein prevented EGF induction of c-fos mRNA. The transformed HLEC line, HLE-B3, showed little stimulation of DNA synthesis in response to EGF and was unaffected by the presence of 12-LOX inhibitors. CONCLUSIONS: N/N1003A cells, like primary cultured human lens epithelial cells or neonatal rat lenses, require 12-LOX activity for EGF dependent growth. This line will be useful for studies of the mechanism of action of 12(S)HETE. (+info)
An early salicylic acid-, pathogen- and elicitor-inducible tobacco glucosyltransferase: role in compartmentalization of phenolics and H2O2 metabolism. (6/401)Treatment of tobacco cell suspension cultures with a fungal elicitor of defense responses resulted in an early accumulation of the phenylpropanoid glucosyltransferase TOGT, along with the rapid synthesis and secretion of scopolin, the glucoside of scopoletin. Elicitor-triggered extracellular accumulation of the aglycone scopoletin and of free caffeic and ferulic acids could only be revealed in the presence of diphenylene iodonium, an inhibitor of extracellular H2O2 production. Our results strongly support a role for TOGT in the elicitor-stimulated production of transportable phenylpropanoid glucosides, followed by the release of free antioxidant phenolics into the extracellular medium and subsequent H2O2 scavenging.

The small intestine can both absorb and glucuronidate luminal flavonoids. (7/401)We have studied the perfusion of the jejunum and ileum in an isolated rat intestine model with flavonoids and hydroxycinnamates and the influence of glycosylation on the subsequent metabolism. Flavone and flavonol glucosides and their corresponding aglycones are glucuronidated during transfer across the rat jejunum and ileum and this glucuronidation occurs without the need for gut microflora. Furthermore, this suggests the presence of glycosidases as well as UDP-glucuronyl transferase in the jejunum. In contrast, quercetin-3-glucoside and rutin are mainly absorbed unmetabolised. The results suggest that the more highly reducing phenolics are absorbed predominantly as glucuronides (96.5%+/-4.6) of the amount absorbed, whereas monophenolic hydroxycinnamates and monophenolic B-ring flavonoids are less predisposed to glucuronidation and higher levels of aglycone (88.1%+/-10.1) are detected on absorption through both the jejunum and ileum.

Induction of apoptosis by arachidonic acid in chronic myeloid leukemia cells. (8/401)The hallmark of chronic myeloid leukemia (CML) is the presence of the bcr-abl oncogene, which is associated with transforming ability and an intrinsic resistance to induction of apoptosis by genotoxic agents. Arachidonic acid (AA), a biologically active fatty acid, plays a crucial role as a mediator of signaling pathways involved in cell proliferation and survival. In this study, we investigated the potential role of AA as a proapoptotic agent in CML. Pretreatment of human CML isolated progenitor cells with AA (100 microM for 18 h) induced 71-75% inhibition of in vitro colony formation of granulocyte-macrophage colony-forming units, multilineage colony-forming units, and erythroid burst-forming units. This inhibition was significantly greater than the effect on normal progenitor cells (19-39% growth inhibition of erythroid burst-forming units, multilineage colony-forming units, and granulocyte-macrophage colony-forming units). AA also inhibited growth of the bcr-abl-transformed cell line H7.bcr-abl A54. In contrast, a minimal effect of AA on inhibition of cell growth was observed in the parental nontransformed NSF/N1.H7 cell line. The antiproliferative effect of AA was associated with apoptosis. Gamma-linolenic acid, a precursor of AA, also inhibited cell growth, whereas other unsaturated and saturated fatty acids had no effect. Pharmacological inhibition of cyclooxygenase, lipooxygenase, and cytochrome P450 monooxygenase enzymes prior to exposure to AA did not rescue cells from the inhibitory effect of AA. Moreover, 5,8,11,14-eicosatetraynoic acid, a nonmetabolizable arachidonate analogue, also inhibited cell growth, suggesting that the effect of AA did not require further metabolism. Treatment with antioxidants prior to stimulation with AA was also ineffective in preventing its antiproliferative effect. Thus, AA inhibited proliferation of CML cells by inducing apoptotic cell death. The signaling mechanisms of AA-induced inhibition of cell growth appeared to be independent of its conversion into eicosanoids or free radical generation. (+info)
Synthesis, Evaluation of Anticancer Activity and QSAR Study of Heterocyclic Esters of Caffeic Acid
Caffeic acid phenethyl ester(CAPE) suppresses the growth of transformed cells such as human breast cancer cells, hepatocarcinoma , myeloid leukemia, colorectal cancer cells, fibrosarcoma, glioma and melanoma. A group of heterocyclic esters of caffeic acid was synthesized using Mitsunobu reaction and the esters were subjected to further structural modification by electrooxidation of the catechol ring of caffeic acid esters in the presence of sodium benenesulfinate and sodium toluensulfinate as nucleophiles. Both heterocycle esters of caffeic acid and their arylsulfonyl derivatives were evaluated for their cytotoxic activity against HeLa, SK-OV-3, and HT-29 cancer cell lines. HeLa cells showed the highest sensitivity to the compounds and heterocyclic esters with no substituent on catechol ring showed better activity compared to their substituted counterparts. QSAR studies reemphasized the importance of molecular shape of the compounds for their cytotoxic activity.
Universidade do Minho: Caffeic acid loading wound dressing : physicochemical and biological characterization
AIM: Caffeic acid has been described as active against bacteria commonly isolated from wound infections. However, its low stability and poor solubility reduce caffeic acid applicability as a pharmaceutical product. These parameters can be enhanced by complexation with cyclodextrin. The main goal of the present work was to incorporate caffeic acid on cyclodextrin-based hydrogels capable of controlled delivery, in order to be used as antibacterial wound dressing. MATERIALS & METHODS: Cyclodextrin-based hydrogels were prepared by direct crosslinking of -cyclodextrin or hydroxypropyl--cyclodextrin with 1,4-butanediol diglycidyl ether in the presence of hydroxypropyl methylcellulose. RESULTS: The hydrogels obtained combine good physicochemical properties (viscoelasticity, superabsorbency and high ability to retain and deliver caffeic acid) with the preservation of caffeic acid antibacterial activity and effect on fibroblasts, with gel--cyclodextrin the most suited. CONCLUSION: The hydrogels obtained ...
The protective effect of caffeic acid on global cerebral ischemia-reperfusion injury in rats | Behavioral and Brain Functions |...
Ischemic stroke is a major cause of death and disability all over the world. Ischemic stroke results from a temporary or permanent reduction of cerebral blood flow that leads to functional and structural damage in different brain regions. Despite decades of intense research, the beneficial treatment of stroke remains limited. In light of this, the search for effective means ameliorating cerebral ischemia-reperfusion injury (CIRI) is one of the major problems of experimental medicine and biology. Recently, the 5-Lipoxygenase (5-LO, a key enzyme metabolizing arachidonic acid to produce leukotrienes) inhibitors have been showed to protect brain against ischemic damage in animal model of cerebral ischemia. Caffeic acid, an inhibitor of 5-LO, is a phenolic compound widely distributed in medicinal plants. The aim of this study was to investigate the effect of caffeic acid on global cerebral ischemia-reperfusion injury in rats. The study was carried out on 45 rats that were randomly divided into five groups:

Additionally, quantitative structure activity indices and composite maps that visualizing nucleophilicity, electrophilicity, and potential energy surface (PES map) are computed and discussed.
Caffeic Acid Prevented LPS-Induced Injury of Primary Bovine Mammary Epithelial Cells through Inhibiting NF-κB and MAPK...
In our previous study, lipopolysaccharide (LPS) significantly reduced the cell viability of primary bovine mammary epithelial cells (bMEC) leading to cell apoptosis, which were prevented by caffeic acid (CA) through inhibiting NF-|i|κ|/i|B activation and reducing proinflammatory cytokine expression. While the underlying mechanism remains unclear, here, we determined that LPS induced the extensive microstructural damage of bMEC, especially the mitochondria and endoplasmic reticulum. Then, the obvious reduction of mitochondrial membrane potential and expression changes of apoptosis-associated proteins (Bcl-2, Bax, and casepase-3) indicated that apoptosis signaling through the mitochondria should be responsible for the cell viability decrease. Next, the high-throughput cDNA sequencing (RNA-Seq) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were employed to verify that the MAPK and JAK-STAT signaling pathways also were the principal targets of LPS. Following, the

Deoxycholic acid - Wikipedia
A number of factors, including diet, obesity, and exercise, affect the level of deoxycholate in the human colon. When humans were switched from their usual diet to a meat, egg and cheese based diet for five days, deoxycholate in their feces increased by factors of 2 to 10 fold. Rats, fed diets with either 30% beef tallow (high fat) or 5% beef tallow (low fat) had almost 2-fold more deoxycholate in their feces on the high fat compared to the low fat diet. In this study, adding the further dietary elements of curcumin or caffeic acid to the rats high fat (30% beef tallow) diet reduced the deoxycholate in their feces to levels comparable to levels seen in the rats on a low fat diet. Curcumin is a component of the spice turmeric, and caffeic acid is a component high in some fruits and spices. Caffeic acid is also a digestive break-down product of chlorogenic acid, high in coffee and some fruits and vegetables. In addition to fats, the type or amount of protein in the diet may ...

Flavonoids and phenolic acids in lettuce: how can we maximize their concentration? And why should we? | International Society...
Flavonoid glycosides and caffeic acid derivatives are widely distributed in the plant kingdom. Many crops owe their red or blue color to the presence of anthocyanins. Their hue depends on their structure, pH and presence of chelating metal ions. Obviously, they are important for visual plant quality. Furthermore, polyphenolic compounds like flavonoids and phenolic acids are reported to have beneficial effects on our health by providing high antioxidant and radical scavenging activity. Yet, studies on health promoting effects are discussed controversially. Results differ between in vitro and in vivo experiments which were conducted with single or several substances or plant extracts. Some of these differences are probably due to varying bioavailability, synergisms between substances and matrix effects. In plants, foliar flavonoids can serve as photoprotectants and shield the photosystem from excess energy and UV radiation. Additionally, they play important roles in the plants interaction with ...

Our present results establish for the first time that MTI-induced apoptosis and 15-LOX-1 expression are linked mechanistically in colorectal cancer cells. The demethylating agents 5-Azadc, 5-azacytidine, and zebularine can induce 15-LOX-1 expression, indicating that methylation may play a role in 15-LOX-1 regulation. 5-Azadc induced 15-LOX-1 expression in a dose- and time-dependent manner and induced growth arrest and apoptosis in Caco-2 colon cancer cells. Inhibiting 15-LOX-1 with caffeic acid (at the 2.2 μmol/L concentration shown to be specific for 15-LOX-1 inhibition) or siRNA attenuated 5-Azadc-induced growth inhibition and apoptosis, indicating a direct relationship between 15-LOX-1 and these biological effects. These findings identify a molecular mechanism by which MTIs induce apoptosis and other cellular effects and further elucidate the role of 15-LOX-1 in human colorectal carcinogenesis. Our findings are consistent with results of other studies, which showed a 15-LOX-1-apoptosis link ...

BACKGROUND:Our aim was to study the effect of caffeic acid phenethyl ester (CAPE) on iNOS and cystathionine gamma-lyase (CSE) of hepatic fibrosis rat, and discuss the anti-hepatic fibrosis mechanism of caffeic acid phenethyl ester. MATERIAL AND METHODS:We observed changes of NO and H2S in serum of hepatic fibrosis rats. Enzyme-linked immunosorbent assay was used to test OD value of iNOS and CSE in serum of each. The expressions of iNOS and CSE protein in the liver were also detected by immunohistochemistry. RESULTS:Compared with the model group, the expression of NO and iNOS was decreased obviously and the level of H2S and CSE was increased in the CAPE group. CONCLUSIONS:CAPE has the effect of anti-hepatic fibrosis, which can be realized through adjusting the expression level of iNOS and CSE.

In vivo and in vitro antıneoplastic actions of caffeic acid phenethyl ester (CAPE): therapeutic perspectives.. Akyol S1, Ozturk G, Ginis Z, Armutcu F, Yigitoglu MR, Akyol O.. Author information. Abstract. Cancer prevention and treatment strategies have attracted increasing interest. Caffeic acid phenethyl ester (CAPE), an active component of propolis extract, specifically inhibits NF-κB at μM concentrations and shows ability to stop 5-lipoxygenase-catalyzed oxygenation of linoleic acid and arachidonic acid. Previous studies have demonstrated that CAPE exhibits antioxidant, antiinflammatory, antiproliferative, cytostatic, antiviral, antibacterial, antifungal, and, most improtantly, antineoplastic properties. The primary goal of the present review is to summarize and critically evaluate the current knowledge regarding the anticancer effect of CAPE in different cancer types..

Propolis Component Shows Anti-Cancer Properties
We found that micromolar concentrations of caffeic acid phenethyl ester blocked voltage-gated sodium channel activity in several invasive cell lines from different cancers, including breast (MDA-MB-231 and MDA-MB-468), colon (SW620) and non-small cell lung cancer (H460). In the MDA-MB-231 cell line, which was adopted as a model, long-term (48h) treatment with 18μM caffeic acid phenethyl ester reduced the peak current density by 91% and shifted steady-state inactivation to more hyperpolarized potentials and slowed recovery from inactivation. The effects of long-term treatment were also dose-dependent, 1μM caffeic acid phenethyl ester reducing current density by only 65%. The effects of caffeic acid phenethyl ester on metastatic cell behaviours were tested on the MDA-MB-231 cell line at a working concentration (1μM) that did not affect proliferative activity. Lateral motility and Matrigel invasion were reduced by up to 14% and 51%, respectively. Co-treatment of caffeic acid phenethyl ester ...
Evaluation of the Effects of Caffeic Acid Phenethyl Ester on Prostaglandin E2 and Two Key Cytokines Involved in Bleomycin...
Objective(s): Pulmonary fibrosis (PF) is the most common outcome of a collection of diverse lung disorders known as interstitial lung diseases. It is proposed that alterations in the levels of fibrogenic mediators and the profibrotic/antifibrotic imbalance play a substantial role in the progression of PF in animal models and possibly in humans. Caffeic acid phenethyl ester (CAPE), an active component of propolis, has numerous biological effects. In the present study, the main objective was to investigate the effects of CAPE on some key mediators including TGF-β1, TNF-α and prostaglandin E2 (PGE2 ) involved in profibrotic/antifibrotic balance and pathogenesis of idiopathic pulmonary fibrosis (IPF). Materials and Methods: In this study, forty male Sprague-Dawley rats were divided into 5 groups (n=8). (1)
Caffeic acid phenethyl ester modulates Helicobacter pylori-induced nuclear factor-kappa B and activator protein-1 expression in...
Caffeic acid phenethyl ester (CAPE), an active component of propolis from honeybee hives (honeybee resin), has anti-inflammatory, anti-carcinogenic and anti-bacterial properties. This study was designed to investigate the anti-inflammatory effects of CAPE on Helicobacter pylori-induced NF-kappaB and AP-1 in the gastric epithelial cell line AGS. Electrophoretic mobility shift assay was used to measure NF-kappaB- and AP-1-DNA binding activity. Western blotting was used to detect IkappaB-alpha and COX-2 expression in AGS cells cocultured with H. pylori. The antiproliferative effect of CAPE was measured by MTT assay. Our results showed that caffeic phenethyl ester inhibits H. pylori-induced NF-kappaB and AP-1 DNA-binding activity in a dose (0.1-25 microg ml(-1) approximately 0.35-88 microM) and time- (15-240 min) dependent manner in AGS cells. Maximum inhibition by CAPE was observed at concentrations of 25 microg ml(-1) ( approximately 88 microM) CAPE prevented H. pylori- and cytokine-induced ...
IJMS | Free Full-Text | Caffeic Acid Phenethyl Ester Suppresses Proliferation and Survival of TW2.6 Human Oral Cancer Cells...
Caffeic acid phenethyl ester (CAPE) is a bioactive component extracted from honeybee hive propolis. Our observations indicated that CAPE treatment suppressed cell proliferation and colony formation of TW2.6 human oral squamous cell carcinoma (OSCC) cells dose-dependently. CAPE treatment decreased G1 phase cell population, increased G2/M phase cell population, and induced apoptosis in TW2.6 cells. Treatment with CAPE decreased protein abundance of Akt, Akt1, Akt2, Akt3, phospho-Akt Ser473, phospho-Akt Thr 308, GSK3β, FOXO1, FOXO3a, phospho-FOXO1 Thr24, phospho-FoxO3a Thr32, NF-κB, phospho-NF-κB Ser536, Rb, phospho-Rb Ser807/811, Skp2, and cyclin D1, but increased cell cycle inhibitor p27Kip. Overexpression of Akt1 or Akt2 in TW2.6 cells rescued growth inhibition caused by CAPE treatment. Co-treating TW2.6 cells with CAPE and 5-fluorouracil, a commonly used chemotherapeutic drug for oral cancers, exhibited additive cell proliferation inhibition. Our study suggested that administration of CAPE is a
Caffeic acid phenethyl ester (CAPE) ameliorates cisplatin-induced hepatotoxicity in rabbit | AVESİS
In this Study, it was aimed to investigate the protective effect of caffeic acid phenethyl ester (CAPE) oil cisplatin hepatotoxicity. Thirty New Zealand rabbits were divided into 5 groups as group 1 (saline-injected control, C), group 2 0% ethanol; vehicle for CAPE, E), group 3 (CAPE), group 4 (cisplatin, CS) and group 5 (cisplatin Plus CAPE, CS + CAPE). Cisplatin caused increased immunoreactivity against inducible nitric oxide synthase (iNOS), but CAPE treatment reduced the immunoreactive hepatocytes. Liver malondialdehide (MDA), nitric oxide (NO(center dot)) levels and xanthine oxidase (XO) activities were higher in CS than in groups C and E. Cisplatin treatment also significantly decreased the tissue reduced glutathione (GSH) concentration compared to groups C and E. CAPE administration normalized the tissue GSH level and XO activity in group CS + CAPE, whereas CAPE treatment did not affect MDA level In group CS + CAPE. In addition, CAPE treatment significantly depressed the cisplatin-induced ...

Beehive extract shows potential as prostate cancer treatment - Healthcanal.com : Healthcanal.com
An over-the-counter natural remedy derived from honeybee hives arrests the growth of prostate cancer cells and tumors in mice, according to a new paper from researchers at the University of Chicago Medicine.. Caffeic acid phenethyl ester, or CAPE, is a compound isolated from honeybee hive propolis, the resin used by bees to patch up holes in hives. Propolis has been used for centuries as a natural remedy for conditions ranging from sore throats and allergies to burns and cancer. But the compound has not gained acceptance in the clinic due to scientific questions about its effect on cells.. In a paper published in Cancer Prevention Research, researchers combined traditional cancer research methods with cutting-edge proteomics to find that CAPE arrests early-stage prostate cancer by shutting down the tumor cells system for detecting sources of nutrition.. If you feed CAPE to mice daily, their tumors will stop growing. After several weeks, if you stop the treatment, the tumors will begin to grow ...
Propolis May Help Treat Amyloidosis
Transthyretin (TTR) is a homotetrameric serum protein associated with amyloidoses such as familial amyloid polyneuropathy and senile systemic amyloidosis. The amyloid fibril formation of TTR can be inhibited through stabilization of the TTR tetramer by the binding of small molecules. In this study, we examined the inhibitory potency of caffeic acid phenethyl ester (CAPE) and its derivatives. Thioflavin T assay showed that CAPE suppressed the amyloid fibril formation of TTR. Comparative analysis of the inhibitory potencies revealed that phenethyl ferulate was the most potent among the CAPE derivatives. The binding of phenethyl ferulate and the selected compounds to TTR were confirmed by the 8-anilino-1-naphthalenesulfonic acid displacement and X-ray crystallography. It was also demonstrated that Bio 30, which is a CAPE-rich commercially available New Zealand propolis, inhibited ...
Fluoride Action Network | Fluoride & Oxidative Stress
SOURCE: Guney M, et al. (2007). Protective effect of caffeic acid phenethyl ester (CAPE) on fluoride-induced oxidative stress and apoptosis in rat endometrium. Environ Toxicol Pharmacol. 24(2):86-91.. Fluoride is a strong, hard anion and cumulative toxic agent. The effect of fluoride intoxication on lipid peroxidation in endometrial tissue and the protective effects of combinations of vitamins E and C in rats were studied. Additionally, the apoptotic changes in endometrial tissue were examined. Experimental groups were as follows: control group; a group treated with 100 mg/l fluoride (F group); and a group treated with 100 mg/l fluoride plus vitamins E and C (F+Vit group). The F and F+Vit groups were treated orally with fluoride for 30 days. Vitamins E and C were injected simultaneously at doses of 50 mg/kg day i.m. and 20 mg/kg day body weight i.p. Extensive formation of DNA strand breaks, the typical biochemical feature of apoptosis, was detected with the use of the terminal deoxynucleotidyl ...
The triple-negative breast cancer (TNBC) patients have a high mortality due to paucity of effective treatments. We have utilized human MDA-MB-231 (MDA-231) BC cells, often serving as a model of TNBC, to determine whether CAPE (caffeic acid phenethyl ester), a major medicinal component of propolis, can combat TNBC as a preventive, therapeutic, and/or adjuvant to chemotherapeutic drugs. We found that CAPE inhibits MDA-231 cell growth in vitro and in vivo. In vitro: CAPE dose-dependently inhibits MDA-231 cell growth and has a strong effect on gene and protein expression without affecting non-tumorigenic cells. It inhibits cell proliferation and anti-apoptotic genes, decreases oncogenes, inflammatory cytokines, cyclins, and certain receptors and growth factors (i.e., EGFR, IGFR-like 1&2, RAR, Egr-1, and NF-\#954;B1&2 transcription factors). CAPE also increases p21 and p27. Notably, CAPE down-regulates mdr-1 gene, considered responsible for the resistance of cancer cells to chemotherapeutic agents, ...

Purification of a new peroxidase catalysing the formation of lignan-type compounds | Biochemical Journal
A novel peroxidase that catalyses the dimerization of ferulic acid or caffeic acid via oxidative coupling and formation of beta beta′-linkage to the lignan-type compounds 8,8′-bis(caffeic acid) or 8,8′-bis(ferulic acid) respectively was purified from the leaves of Bupleurum salicifolium. The enzyme, for which the name caffeate peroxidase is proposed, was purified 2700-fold. It is a glycoprotein and has an Mr of 38,000 as determined by gel filtration and SDS/PAGE. The Km values for ferulic acid and caffeic acid were 0.24 mM and for H2O2 0.04 mM with caffeic acid and 0.48 mM with ferulic acid. The purified peroxidase does not exhibit activity on other phenylpropanoids tested and has no detectable phenol oxidase or NADPH oxidase activity. The caffeate peroxidase could be involved in the biosynthesis of lignans. ...
Caffeic Acid Disks
Cryptococcosis, specifically caused by Cryptococcus neoformans, is a subacute or chronic fungal infection with several manifestations. It is commonly observed as a disseminated disease in the immunocompromised patient with approximately two thirds of patients experiencing meningitis.(3,5) Because of the wide spectrum of Cryptococcosis and the opportunistic nature of such infection, rapid laboratory identification of Cryptococcus neoformans is necessary so that therapy can be immediately initiated. The presumptive identification of Cryptococcus neoformans is based on the presence of an encapsulated yeast (using India ink), the absence of pseudohyphae, the failure to utilize an inorganic nitrate substance, and the ability to produce urease. The final identification of C. neoformans is usually based on typical substrate utilization patterns and brown pigment production in the presence of caffeic acid.(2,3,5). The brown pigmented colonies of Cryptococcus neoformans were observed by Staib in 1962 ...

Authors: A.HAKAN AKTAŞ, GÜLSÜM YAŞAR, GÜLEREN ÖZKAN ALSANCAK, ŞAHİNDE DEMİRCİ Abstract: In this study, four hydroxycinnamic acids, namely 3,4-dihydroxycinnamic acid, 4-hydroxycinnamic acid, 4-hydroxy --3- methoxycinnamic acid and 4-hydroxy-3,5-dimethoxycinnamic acid, were titrated conductimetrically and potentiometrically using triethylamine and tetrabutylammonium hydroxide in acetonitrile, 2-propanol, and pyridine solvents under a nitrogen atmosphere at 25 ^oC. In conductimetric titration with tetrabutylammonium hydroxide all of the compounds exhibited conventional stoichiometric titration curves in 2-propanol . As is evident from the titration curves, all these compounds gave two well-defined end points. The first end point corresponds to exactly one equivalent and the second one to the two equivalents of the base. In conductimetric titration with tetrabutylammonium hydroxide, all of the acids (except caffeic acid) show two end points in pyridine solvent. These compounds were ...

Remarkable enhancement of bacterial inactivation in wastewater through promotion of solar photo-Fenton at near-neutral pH by...
In this work, the near-neutral photo-Fenton process, as a means of wastewater disinfection, was enhanced by the addition of Organic Acids (OAs), namely citric, ascorbic, tartaric and caffeic acid. The addition of OAs exhibited significant bacterial inactivation enhancement, compared to the classic photo-Fenton systems (Fe2+/H2O2/solar and Fe3+/H2O2/solar). The improved disinfection performance was not attributed to pH variations by the addition of OAs, but to the increase of the initial dissolved iron in the system, facilitating the Fe3+/Fe2+ turnover in the catalytic photo-Fenton reaction and consequently, the hydroxyl radicals production. For citric and tartaric acid, increased photo-activity of the complexes was associated with their high capability to complex Fe3+ and to promote ligand-to-metal charge transfer (LMCT), which is of key importance to feed Fe2+ to the Fenton process. On the other hand, for ascorbic and caffeic acid, the acceleration of the homogeneous Fenton reaction was ...

Practical Fragments: Rad fragments revisited
One of the best fragments identified in the previous work was L-tryptophan methyl ester (compound 1), so the researchers naturally tried substituting the methyl group. A phenethyl ester (compound 5c) gave a satisfying 10-fold boost in potency, but this turned out to be the best they could get: shorter or longer linkers were both less active, and modifications around the phenyl ring gave marginal improvements at best. Also, changing the ester to an amide decreased affinity. They were, however, able to improve potency another order of magnitude by acylating the nitrogen (compound 6a ...

A.Vogel Heart Care Hawthorn berry Tincture | Online Store
Hawthorns active components are mostly flavonoids (luteolin, apigenin, vitexin, rutin, and quercetin as glycosides) and procyanidins. Hawthorn is also a source of tannins or polyphenols (oligomeric cathechins and epicathechins), carboxylic acids (caffeic acid), triterpenes and simple amines (choline, acetylcholine and tyramine). Researchers were unable to find one major active ingredient. It would seem that the therapeutic effect of Hawthorn, like that of many other herbs, rests on the synergy of all of its components.(1). The various in vivo and in vitro studies have identified many of Hawthorns therapeutic effects:. Increase of cardiac contractility (positive inotropic effect). As a result, heart efficiency and ejection fraction are increased.(2). Peripheral resistance reduction (post-charge reduction). The lesser the resistance, the lesser the effort needed by the heart. The final effect is a reduction in oxygen consumption. (2). Coronary vasodilator (improves heart irrigation and oxygen ...
Capes On the Couch - Where Comics Get Counseling: Stress and Triplets... You Have NO Idea!
The Stepford Cuckoos episode allowed Anthony and I to discuss a smidgen of what sibling multiples may or may not go through in their lives. As usual, in no way was this a comprehensive discussion, so I figured a few written words could help flesh out the narrative. Unfortunately (fortunately?) I did a bit of reading on the subject, which led to watching something on the subject, which led to confusion, anger, and a willingness to make an apology for my field for something I didnt do... Im a bit off course. Breathe, doc. Your wife always tells you to breathe. I found out about the Dr. Peter Neubauer study involving the Triplets Pizza Brothers. If that sounds like the corny premise for an evening sitcom, its because I didnt mention the intentional separation of families from infants to study their development into adulthood, keeping everyone in secrecy and the ultimate footnote being one of them committing suicide. But hey! At least they learned what type of women they liked and they
Cape May Warblers | The Roger Tory Peterson Institute of Natural History
