p-Hydroxyphenylacetic acid, also known as 4-hydroxybenzeneacetate, is classified as a member of the 1-hydroxy-2-unsubstituted benzenoids. 1-Hydroxy-2-unsubstituted benzenoids are phenols that are unsubstituted at the 2-position. p-Hydroxyphenylacetic acid is considered to be slightly soluble (in water) and acidic. p-Hydroxyphenylacetic acid can be synthesized from acetic acid. It is also a parent compound for other transformation products, including but not limited to, methyl 2-(4-hydroxyphenyl)acetate, ixerochinolide, and lactucopicrin 15-oxalate. p-Hydroxyphenylacetic acid can be found in numerous foods such as olives, cocoa beans, oats, and mushrooms. p-Hydroxyphenylacetic acid can be found throughout all human tissues and in all biofluids. Within a cell, p-hydroxyphenylacetic acid is primarily located in the cytoplasm and in the extracellular space. p-Hydroxyphenylacetic acid is also a microbial metabolite produced by Acinetobacter, Clostridium, Klebsiella, Pseudomonas, and Proteus. Higher ...

The phenylacetic acid (PA) degradative pathway is the central pathway by which complex aromatic compounds (e.g. styrene) get degraded. Upper pathways for different aromatic compounds converge at common intermediate phenylacetyl-CoA, which is then metabolized to succinyl-CoA and acetyl-CoA. We previously made a link in Burkholderia cenocepacia between phenylacetic acid (PA) degradation and virulence by showing that insertional mutagenesis of paaA and paaE results in PA-conditional growth and an attenuated killing phenotype in the Caenorhabditis elegans model of infection. Insertional mutagenesis of paaK1, which encodes a phenylacetyl-CoA ligase, did not result in a PA-conditional growth probably due to the presence of a second similar gene (paaK2) encoding another phenylacetyl-CoA ligase (PaaK2). Recently published crystallographic and enzyme kinetics studies comparing the two ligases show that PaaK1 is better able to bind hydroxylated PA derived molecules such as 3-hydroxyphenylacetic (3-OHPA) acid and

Styrene is a toxic and potentially carcinogenic alkenylbenzene used extensively in the polymer processing industry. Significant quantities of contaminated liquid waste are generated annually as a consequence. However, styrene is not a true xenobiotic and microbial pathways for its aerobic assimilation, via an intermediate, phenylacetic acid, have been identified in a diverse range of environmental isolates. The potential for microbial bioremediation of styrene waste has received considerable research attention over the last number of years. As a result the structure, organisation and encoded function of the genes responsible for styrene and phenylacetic acid sensing, uptake and catabolism have been elucidated. However, a limited understanding persists in relation to host specific regulatory molecules which may impart additional control over these pathways. In this study the styrene degrader Pseudomonas putida CA-3 was subjected to random mini-Tn5 mutagenesis and mutants screened for altered styrene

A new and sensitive method for the fluorometric determination of homovanillic acid using o-dianisidine-peroxidase system was established. Under the optimum conditions, the calibration curve was linear from 0.5μg/ml to 20μg/ml (0.5-20μg/tube) of homovanillic acid, and coefficients of variation was below 5 percents. Salicylic acid, glucose, urea, p-hydroxyphenylacetic acid, and homogentisic acid did not interfer with the value of homovanillic acid, but the coexistence of uric acid, dopamine, and serotonine caused clearly decreases in the homovanillic acid value by the present method.. ...

Next, we carried out the reaction under the optimized conditions for phenylacetic acid 2p but in the absence of any indole (Scheme 4A). This experiment revealed that our catalytic system is able to hydrogenate the carboxylic acid to the corresponding alcohol in moderate yields (14% of 2-phenylethanol 5 and 17% of 2-phenetyl phenylacetate 8 were detected, Scheme 4A). The experiment at shorter reaction times and using phenylacetaldehyde 9 as starting material, afforded 2-phenylethanol 5 in good yields (76%, Scheme 4B).. At this point it was interesting to compare the reactivity of several possible alkylating agents, all of them being related derivatives of phenylacetic acid 2p. Thus, reactions of indole 1a were performed in the presence of the [Co(acac)3/Triphos (L1)/Al(OTf)3] system at 140 °C and 30 bar of H2, using phenylacetic acid 2p, phenylacetaldehyde 9, phenethyl alcohol 5 and methyl phenylacetate 6 (usually formed from phenylacetic acid and methanol coming from MCPE cleavage) (Scheme ...

The disposition and metabolism of H3-tyramine was investigated in different regions of the central nervous system after the intraventricular injection of the labeled amine. The hypothalamus contained the highest concentration of radioactive amines. The ratio of amines to acidic-neutral metabolites was higher in the hypothalamus than in other analyzed regions of the brain. In all analyzed regions of the central nervous system, with the exception of the striatum, the major part of the radioactivity of the amine fraction was associated with H3-octopamine. In the striatum all the radioactivity of the amine fraction was associated with unchanged H3-tyramine. The deaminated H3-metabolites of tyramine were isolated and identified in different regions of the brain. The major metabolite in all analyzed regions was found to be H3-p-hydroxyphenylacetic acid and the minor was found to be H3-p-hydroxyphenylethanol. Although both H3-phydroxyphenylacetic acid and H3-p-hydroxyphenylethanol were present in the ...

The hpaB gene encoding an aromatic hydroxylase of Escherichia coli ATCC 11105, a penicillin G acylase-producing strain, has been cloned and expressed in E. coli K-12. This gene was located near the pacA gene coding for penicillin G acylase. The hydroxylase has a molecular mass of 59,000 Da, uses NADH as a cosubstrate, and was tentatively classified as a 4-hydroxyphenylacetic acid hydroxylase, albeit it exhibited a rather broad substrate specificity acting on different monohydric and dihydric phenols. E. coli W, C, and B as well as Klebsiella pneumoniae M5a1 and Kluyvera citrophila ATCC 21285 (a penicillin G acylase-producing strain) but not E. coli K-12 contained sequences homologous to hpaB. Our results support the hypothesis that hpaB is a component of the 4-hydroxyphenylacetic acid degradative pathway of E. coli W. ...

4-hydroxyphenylacetate 3-monooxygenase (EC 1.14.14.9) is an enzyme that catalyzes the chemical reaction 4-hydroxyphenylacetate + FADH2 + O2 ⇌ {\displaystyle \rightleftharpoons } 3,4-dihydroxyphenylacetate + FAD + H2O This reaction is the first step in a pathway found in enteric bacteria such as Escherichia coli and soil bacteria such as Pseudomonas putida which degrades 4-hydroxyphenylacetate (4-HPA), allowing these bacteria to use 4-HPA and other aromatic compounds found in mammalian digestive tracts or in soil as a carbon source. While most known flavin monooxygenases use NADH or NADPH as substrates (and use the flavins FAD or FMN as prosthetic groups ), this enzyme is part of a two-component system, in which a flavin oxidoreductase partner (EC 1.5.1.37) regenerates FADH2 by oxidizing NADH to NAD+. hpaB and hpaC, the 4-HPA oxygenase and reductase partner proteins (respectively) of E. coli strain W, were the first two-component flavin monoxygenase system identified.

Synthesis of penicillinamidohydrolase (penicillin acylase, EC 3.5.1.11) inEscherichia coli is subjected to the absolute catabolite repression by glucose and partial repression by acetate. Both types of catabolite repression of synthesis of the enzyme inEscherichia coli are substantially influenced by cyclic 3,′5′-adenosinemonophosphate (cAMP). Growth diauxie in a mixed medium containing glucose and phenylaoetic acid serving as carbon and energy sources is overcome by cAMP. cAMP does not influence the basal rate of the enzyme synthesis (without the inducer). Derepression of synthesis of penicillinamidohydrolasa by cAMP in a medium with glucose and inducer (phenylacetic acid) is associated with utilization of the inducer, due probably to derepression of other enzymes responsible for degradation of phenylacetic acid. Lactate can serve as a

Objective: To investigate the effects of metabotropic slutamate receptor mGluR5 specific agonist CHPG on the proliferation of human embryonic cortical neural stem cells( NSCs) and the related molecular mechanism. Methods:MTT assay and diameter measuring of neurospheres were used to analyze the effects of mGluR5 agonist CHPG on proliferation of human embryonic NSCs. The effects of mGluR5 agonist CHPG on the cell cycle and apoptosis of human NSCs were analyzed with flow cytometer. The expression of phosphorylated ERK,JNK and p38 MAPKs in human NSCs were examined with Western Blot after mGluR5 agonist CHPG treatment. Results: mGluR5 agonist CHPG promoted proliferation of human embryonic cortical NSCs. The number of cells in S and G2 / M phass significantly increased in CHPG groups compared to that of the control group( P 0. 05),meanwhile the number of cells in G1 / G0 phase remarkably decreased( P 0. 05); the percentage of early and late apoptic cells significantly decreased in CHPG groups( P 0. 05).

Pullulan esters are prepared by the reaction of pullulan with aliphatic or aromatic fatty acids or their derivatives in the presence of suitable solvents and/or catalysers. Said pullulan esters can be shaped by compression molding or extrusion at elevated temperature or by evaporation of solvents from their solutions to form shaped bodies, such as films or coatings which are practically impermeable to atmospheric oxygen in thin layers and unaffected by oils and fats so as to provide valuable packaging materials for food, pharmaceuticals, and other oxygen sensitive materials.

A high concentration of PTH can promote the transformation of preosteoclasts and stromal cells into osteoclasts. Highly active osteoclasts dissolve bone minerals by secreting acid onto the isolated surface, and simultaneously break down the bone matrix by secreting collagenase and hydrolase. Increased levels of glycylproline, the end product of collagen metabolism, were found when bone collagen was disrupted. Glycylproline can be further digested by prolidase to glycine and proline, and we found decreased glycylproline and increased glycine levels in urine collected from the LCG rats. Glycine is involved in the synthesis of collagen. Phenylacetylglycine is a glycine conjugate of phenylacetic acid. Decreased glycylproline and increased glycine and phenylacetylglycine levels in urine suggested disruption of bone collagen. The results of our study suggest that glycylproline, glycine, and phenylacetylglycine could be involved in the metabolic pathway of the degradation and biosynthesis of bone ...

Sodium phenylacetate (PA) and sodium phenylbutyrate (PB) are aromatic fatty acids that can effect differentiation in a variety of cell lines at doses that may be clinically attainable. We have studied the impact of these two agents on lineage- and differentiation stage-specific antigen expression, proliferation, apoptosis, and clonogenic cell survival in primary cultures of bone marrow samples from patients with myeloid neoplasms at presentation and in remission and from normal volunteers. PB inhibited the proliferation of primary acute myeloid leukemia cells in suspension culture with an ID50 of 6.6 mM, similar to its ED50 in cell lines. At higher doses (,/=5 mM), PB also induced apoptosis. PB inhibited clonogenic leukemia cell growth with a median ID50 of less than 2 mM; however, colony-forming units-granulocyte/macrophage from patients with myelodysplasia and normal volunteers were inhibited with a similar ID50. In contrast to PB, its metabolite PA had no significant effect on either acute ...

The flavonoid quercetin, or its metabolites, inhibit chemical carcinogenesis in rodents and may have a role in the prevention of human cancers. Quercetin exposure in human populations results from the dietary intake of various plant foods; high concentrations of quercetin are found in apples, onions, tea, and red wine. Determination of the relationship between dietary intake and cancer risk depends on the characterization of quercetin intake. The development and use of biomarkers for quercetin intake may provide a basis for the objective classification of this exposure. One possible biomarker is metabolic products of quercetin. We report the development of a high-performance liquid chromatography (HPLC)-based assay for quantitation of quercetin metabolites in human urine. The metabolites include 3,4-dihydroxyphenylacetic acid (homoprotocatechuic acid), metahydroxyphenylacetic acid, and 4-hydroxy-3-methoxyphenylacetic acid (homovanillic acid). The assay has only two major steps, ether extraction ...

4-Hydroxyphenylacetic acid (4HPAA) is an important building block for synthesizing drugs, agrochemicals, biochemicals, etc. 4HPAA is currently produced exclusively via petrochemical processes and the process is environmentally unfriendly and unsustainable. Microbial cell factory would be an attractive approach for 4HPAA production. In the present study, we established a microbial biosynthetic system for the de novo production of 4HPAA from glucose in Escherichia coli. First, we compared different biosynthetic pathways for the production of 4HPAA. The yeast Ehrlich pathway produced the highest level of 4HPAA among these pathways that were evaluated. To increase the pathway efficiency, the yeast Ehrlich pathway enzymes were directedly evolved via error-prone PCR. Two phenylpyruvate decarboxylase ARO10 and phenylacetaldehyde dehydrogenase FeaB variants that outperformed the wild-type enzymes were obtained. These mutations increased the in vitro and in vivo catalytic efficiency for converting 4

3,4-dihydroxyphenylacetate (DHPA) dioxygenase (DHPAO) from Pseudomonas aeruginosa (PaDHPAO) was overexpressed in Escherichia coli and purified to homogeneity. As the enzyme lost activity over time, a protocol to reactivate and conserve PaDHPAO activity has been developed. Addition of Fe(II), DTT and ascorbic acid or ROS scavenging enzymes (catalase or superoxide dismutase) was required to preserve enzyme stability. Metal content and activity analyses indicated that PaDHPAO uses Fe(II) as a metal cofactor. NMR analysis of the reaction product indicated that PaDHPAO catalyzes the 2,3-extradiol ring-cleavage of DHPA to form 5-carboxymethyl-2-hydroxymuconate semialdehyde (CHMS) which has a molar absorptivity of 32.23 mM-1cm-1 at 380 nm and pH 7.5. Steady-state kinetics under air-saturated conditions at 25°C and pH 7.5 showed a Km for DHPA of 58 ± 8 μM and a kcat of 64 s-1, indicating that the turnover of PaDHPAO is relatively fast compared to other DHPAOs.

Anti-ϑ serum treatment of cells from immunized mice before their transfer to irradiated non-immune recipients decreased the ability of such cells to be stimulated by hapten on both homologous and heterologous carriers over a wide range of antigen doses. The anti-ϑ treatment was shown to affect only thymus-dependent (T) cells, since the number of bone marrow-derived (B) cell precursors was unaltered. Thus, specific T cells contribute significantly, not only to stimulation by the hapten on the homologous carrier, but also when hapten is presented on heterologous and even poorly immunogenic carriers. These results are interpreted as indicating a role for collaborative interactions of hapten-specific T cells with B cells specific for the same determinant. Such interactions were found at low antigen concentration. Results are discussed with relation to the mechanism of B cell stimulation.. ...
