Coupling of the peroxidase and cyclooxygenase reactions of prostaglandin H synthase. (1/535)

Interrelations between peroxidase and cyclooxygenase reactions catalyzed by prostaglandin endoperoxide synthase (prostaglandin H synthase) were analyzed in terms of the mutual influence of these reactions. The original branched-chain mechanism predicts competition between these two reactions for enzyme, so that peroxidase cosubstrate should inhibit the cyclooxygenase reaction and the cyclooxygenase substrate is expected to inhibit the peroxidase reaction. In stark contrast, the peroxidase reducing substrate is well known to strongly stimulate the cyclooxygenase reaction. In the present work the opposite effect, the influence of the cyclooxygenase substrate on the peroxidase reaction was studied. Experiments were conducted on the effect of arachidonic acid on the consumption of p-coumaric acid by prostaglandin H synthase and 5-phenyl-4-pentenyl-1-hydroperoxide. Neither the steady-state rates nor the total extent of p-coumaric acid consumption was affected by the addition of arachidonic acid. This suggests that the cyclooxygenase substrate does not influence observable velocities of the peroxidase reaction, namely oxidation and regeneration of the resting enzyme. The data support coupling of the cyclooxygenase and peroxidase reactions. A combination of the branched-chain and tightly coupled mechanisms is proposed, which includes a tyrosyl radical active enzyme intermediate regenerated through the peroxidase cycle. Numerical integration of the proposed reaction scheme agrees with the observed relations between peroxidase and cyclooxygenase reactions in the steady state.  (+info)

Genetic analysis of a chromosomal region containing vanA and vanB, genes required for conversion of either ferulate or vanillate to protocatechuate in Acinetobacter. (2/535)

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.  (+info)

Bacterial photoreceptor with similarity to photoactive yellow protein and plant phytochromes. (3/535)

A phytochrome-like protein called Ppr was discovered in the purple photosynthetic bacterium Rhodospirillum centenum. Ppr has a photoactive yellow protein (PYP) amino-terminal domain, a central domain with similarity to phytochrome, and a carboxyl-terminal histidine kinase domain. Reconstitution experiments demonstrate that Ppr covalently attaches the blue light-absorbing chromophore p-hydroxycinnamic acid and that it has a photocycle that is spectrally similar to, but kinetically slower than, that of PYP. Ppr also regulates chalcone synthase gene expression in response to blue light with autophosphorylation inhibited in vitro by blue light. Phylogenetic analysis demonstrates that R. centenum Ppr may be ancestral to cyanobacterial and plant phytochromes.  (+info)

Mitochondrial metabolism of pyruvate is required for its enhancement of cardiac function and energetics. (4/535)

Pyruvate augmentation of contractile function and cytosolic free energy of ATP hydrolysis in myocardium could result from pyruvate catabolism in the mitochondria or from increased ratio of the cytosolic NAD-/NADH redox couple via the lactate dehydrogenase equilibrium. OBJECTIVE: To test the hypothesis that cytosolic oxidation by pyruvate is sufficient to increase cardiac function and energetics. METHODS: Isolated working guinea-pig hearts received 0.2 mM octanoate +/- 2.5 mM pyruvate as fuels. alpha-Cyano-3-hydroxycinnamate (COHC, 0.6 mM) was administered to selectively inhibit mitochondrial pyruvate uptake without inhibiting pyruvate's cytosolic redox effects or octanoate oxidation. The effects of pyruvate and COHC on sarcoplasmic reticular- Ca2+ handling were examined in 45Ca-loaded hearts. RESULTS: Pyruvate increased left ventricular stroke work and power 40%, mechanical efficiency 29%, and cytosolic ATP phosphorylation potential nearly fourfold. 14CO2 formation from [1-14C]pyruvate was inhibited 65% by COHC, and octanoate oxidation, i.e. 14CO2 formation from [1-14C]octanoate, concomitantly increased threefold. COHC prevented pyruvate enhancement of left ventricular function, mechanical efficiency and cytosolic phosphorylation potential, but did not alter respective levels in pyruvate-free control hearts and augmented cytosolic oxidation by pyruvate. Pyruvate increased sarcoplasmic reticular Ca2+ turnover, i.e. Ca2+ uptake and release, as indicated by 62% decrease in caffeine-induced 45Ca release following 40 min 45Ca washout (P < 0.01). In presence of COHC, pyruvate did not lower caffeine-induced 45Ca release; thus. COHC abrogated pyruvate enhancement of Ca2+ turnover (P < 0.001). CONCLUSION: Pyruvate oxidation of cytosolic redox state is not sufficient to increase cardiac function, cytosolic energetics and sarcoplasmic reticular Ca2+ turnover when mitochondrial pyruvate transport is disabled; thus, mitochondrial metabolism of pyruvate is essential for its metabolic inotropism.  (+info)

Theoretical elucidation of activity differences of five phenolic antioxidants. (5/535)

AIM: To verify the effectiveness of structure-activity relationship (SAR) and theoretical calculation methods for antioxidants. METHODS: Preliminary elucidation on the differences of activities of 5 antioxidants was performed by SAR. Then semiempirical quantum chemistry method AM1 was employed to calculate the delta HOF value, the difference between the heat of formation of antioxidant and its free radical, which was used as a theoretical parameter to elucidate the differences of activities of the antioxidants thoroughly. RESULTS: delta HOF values of antioxidants were obtained as follows: ferulic acid, 150.58 kJ.mol-1; anion of ferulic acid, 122.64 kJ.mol-1; modified ferulic acid, 137.70 kJ.mol-1; anion of modified ferulic acid, 118.99 kJ.mol-1; salvianic acid, 134.17 kJ.mol-1; rutin, 137.83 kJ.mol-1, L-EGCG, 124.39 kJ.mol-1; paeonol, 176.79 kJ.mol-1. The differences of the antioxidant activities were elucidated, and how to further enhance the antioxidant activity was investigated as well. CONCLUSION: The SAR and calculation methods are rather effective to elucidate the differences of antioxidant activities, and present some new clues for structural modification of antioxidants to increase their activities.  (+info)

An early salicylic acid-, pathogen- and elicitor-inducible tobacco glucosyltransferase: role in compartmentalization of phenolics and H2O2 metabolism. (6/535)

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.  (+info)

The small intestine can both absorb and glucuronidate luminal flavonoids. (7/535)

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.  (+info)

Biochemical characterization of the suberization-associated anionic peroxidase of potato. (8/535)

The anionic peroxidase associated with the suberization response in potato (Solanum tuberosum L.) tubers during wound healing has been purified and partially characterized at the biochemical level. It is a 45-kD, class III (plant secretory) peroxidase that is localized to suberizing tissues and shows a preference for feruloyl (o-methoxyphenol)-substituted substrates (order of substrate preference: feruloyl > caffeoyl > p-coumaryl approximately syringyl) such as those that accumulate in tubers during wound healing. There was little influence on oxidation by side chain derivatization, although hydroxycinnamates were preferred over the corresponding hydroxycinnamyl alcohols. The substrate specificity pattern is consistent with the natural substrate incorporation into potato wound suberin. In contrast, the cationic peroxidase(s) induced in response to wound healing in potato tubers is present in both suberizing and nonsuberizing tissues and does not discriminate between hydroxycinnamates and hydroxycinnamyl alcohols. A synthetic polymer prepared using E-[8-(13)C]ferulic acid, H(2)O(2), and the purified anionic enzyme contained a significant amount of cross-linking through C-8, albeit with retention of unsaturation.  (+info)

Enzyme-catalyzed synthesis has been widely studied with lipases (EC 3.1.1.3), but feruloyl esterases (FAEs; EC 3.1.1.73) may provide advantages such as higher substrate affinity and regioselectivity in the synthesis of hydroxycinnamate saccharide esters. These compounds are interesting because of their amphiphilicity and antioxidative potential. Synthetic reactions using mono- or disaccharides as one of the substrates may moreover direct new routes for biomass upgrading in the biorefinery. The paper reviews the available data for enzymatic hydroxycinnamate saccharide ester synthesis in organic solvent systems as well as other enzymatic hydroxycinnamate acylations in ionic liquid systems. The choice of solvent system is highly decisive for enzyme stability, selectivity, and reaction yields in these synthesis reactions. To increase the understanding of the reaction environment and to facilitate solvent screening as a crucial part of the reaction design, the review explores the use of activity ...
Ferulic acid (4-hydroxy-3-methoxycinnamic acid) (FA) is a ubiquitous health beneficial phenolic acid. Although FA has shown a diversity of biological activities including anti-inflammatory, antihypercholesterolemic and anticancer bioactivities, studies revealing its adverse effects are accumulating. Recently, 3D-cultures are shown to exhibit uniquely biological behaviors different from that of 2D cultures. To understand whether the cytotoxicity of FA against the T24 cell line (a bladder cancer cell line) in 2D-culture could consistently retain similar bioactivity if cultured in the 3D-systems, we conducted this experiment with 2 mM FA. Much higher cytotoxicity was found for 3D- than 2D-culture, showing (2D vs. 3D): apoptotic rates, 64% and 76%; cell killing rates, |svg style=vertical-align:-0.1638pt;width:68.662498px; id=M1 height=15.9 version=1.1 viewBox=0 0 68.662498 15.9 width=68.662498 xmlns:xlink=http://www.w3.org/1999/xlink xmlns=http://www.w3.org/2000/svg||g transform
Surface-Enhanced Raman Spectroscopy (SERS) is a powerful surface-sensitive technique to study the vibrational properties of analytes at very low levels of concentration. In particular, detection of bioactive molecules, specifically antioxidants, is an area of interest to gain insights into the reproducible and quantitative SERS-determination. In this study, SERS measurements were systematically evaluated for ferulic acid, p-coumaric acid, caffeic acid and sinapic acid. The study objective in this research was to: 1) prepare and characterize SERS-active silver colloids; 2) cluster the as-obtained colloids through Principal Component Analysis on the basis of concentration and nanoparticle size; and 3) develop a highly sensitive SERS-based method for phenolic antioxidant detection. The reliability of the proposed method was demonstrated through detection of the phenolic antioxidants evaluated at low levels of concentration. In particular, sinapic acid was evaluated for the first time, with a limit ...
Catalyzes the insertion of one atom of molecular oxygen into position 2 of the phenyl ring of 3-(3-hydroxyphenyl)propionate (3-HPP) and hydroxycinnamic acid (3HCI).
Lignans are mainly dimers of 4-hydroxycinnamic acids (HCAs) and reduced analogs thereof which are produced in Nature through phenol oxidative coupling (POC) as the primary C-C or C-O bond-forming reaction under the action of the enzymes peroxidases and laccases. They present a large structural variety and particularly interesting biological activities, therefore, significant efforts has been devoted to the development of efficient methodologies for the synthesis of lignans isolated from natural sources, analogs and hybrids with other biologically interesting small molecules. We summarize in the present review those methods which mimic Nature for the assembly of the most common lignan skeleta by using either enzymes or one-electron inorganic oxidants to effect POC of HCAs and derivatives, such as esters and amides, or cross-POC of pairs of HCAs or HCAs with 4-hydrocycinnamyl alcohols. We, furthermore, provide outlines of mechanistic schemes accounting for the formation of the coupled products and, where

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 ...
Ferulic acid is a highly abundant phenolic phytochemical which is present in plant cell walls. Ferulic acid is a phenolic acid that can be absorbed by the small intestine and excreted through the urine. It is one of the most abundant phenolic acids in plants, varying from 5 g/kg in wheat bran to 9 g/kg in sugar-beet pulp and 50 g/kg in corn kernel. It occurs primarily in seeds and leaves both in its free form (albeit rarely) and covalently linked to lignin and other biopolymers. It is usually found as ester cross-links with polysaccharides in the cell wall, such as arabinoxylans in grasses, pectin in spinach and sugar beet, and xyloglucans in bamboo. It also can cross-link with proteins. Due to its phenolic nucleus and an extended side chain conjugation (carbohydrates and proteins), it readily forms a resonance-stabilized phenoxy radical which accounts for its potent antioxidant potential. Food supplementation with curcumin and ferulic acid is considered a nutritional approach to reducing ...
A molecularly imprinted polymer was synthesized for the purpose of sinapic acid isolation from Egyptian nutraceutical Botrytis italica, L. (broccoli) due to its prominent medicinal and wide pharmacological activities. A computational study was first developed to determine the optimal template to functional monomer molar ratio. Based on the computational results, five polymers were synthesized using a bulk polymerization method with sinapic acid as the template molecule. Evaluation of the synthesized polymers binding performance was carried out using batch rebinding assay, which revealed that the molecularly imprinted polymer of molar ratio (1:4:20), template to functional monomer (4-vinyl pyridine) to crosslinker (ethylene glycol dimethacrylate) was of optimum performance, thus, this polymer was applied for sinapic acid isolation from closely related analogues ...

Phenolic acids are secondary plant compounds widespread in nature, which have potentially anticarcinogenic properties. In this study, the effect of ferulic acid (FA), which is the most common hydroxycinnamic acid in grain, on the mechanisms of colon carcinogenesis and tumor progression was investigated in a human colon carcinoma cell culture model (HT29 clone 19A). Antiproliferative and proapoptotic effects of FA were analysed. By means of proteome analysis (2D-PAGE, 2D-DIGE, LC-ESI-MS/MS) the influence of FA on the protein expression was investigated. It could be shown, that FA caused cytotoxic effects and significantly induced apoptosis only at high concentrations (> 3 mM). Simultaneously, the changes at the proteome level after FA-treatment were relatively small. Only at non-physiological concentrations did FA influence the processes of growth in HT29 clone 19A cells. « ...

Diskolorasi gigi telah menjadi masalah estetik bagi banyak orang. Diskolorasi gigi dapat disebabkan oleh banyak faktor seperti penggunaan tembakau, minuman dan makanan berwarna, maupun trauma pada gigi. Perawatan bleaching merupakan salah satu solusi yang dapat mengatasi masalah diskolorasi pada gigi. Perawatan bleaching dibagi dua, yaitu bleaching ekstrakorona untuk diskolorasi pada gigi vital dan bleaching intrakorona untuk diskolorasi pada gigi nonvital. Bleaching ekstrakorona memiliki berbagai efek samping yang dapat terjadi pada jaringan keras gigi, mukosa mulut, dan restorasi gigi , akan tetapi masalah yang sering dikeluhkan oleh pasien dalam perawatan ekstrakorona bleaching, yaitu hipersensitivitas gigi. Hipersensitivitas pada bleaching ektrakorona dipengaruhi banyak faktor, yaitu pasien yang memiliki riwayat hipersensitivitas, konsentrasi bahan bleaching, lamanya terpapar bahan bleaching, dan kondisi gigi pasien seperti erosi servikal, restorasi besar, dan retak pada email.
