Crystal structure of human muscle aldolase complexed with fructose 1,6-bisphosphate: mechanistic implications. (1/466)

Fructose 1,6-bisphosphate aldolase catalyzes the reversible cleavage of fructose 1,6-bisphosphate and fructose 1-phosphate to dihydroxyacetone phosphate and either glyceraldehyde 3-phosphate or glyceraldehyde, respectively. Catalysis involves the formation of a Schiff's base intermediate formed at the epsilon-amino group of Lys229. The existing apo-enzyme structure was refined using the crystallographic free-R-factor and maximum likelihood methods that have been shown to give improved structural results that are less subject to model bias. Crystals were also soaked with the natural substrate (fructose 1,6-bisphosphate), and the crystal structure of this complex has been determined to 2.8 A. The apo structure differs from the previous Brookhaven-deposited structure (1ald) in the flexible C-terminal region. This is also the region where the native and complex structures exhibit differences. The conformational changes between native and complex structure are not large, but the observed complex does not involve the full formation of the Schiff's base intermediate, and suggests a preliminary hydrogen-bonded Michaelis complex before the formation of the covalent complex.  (+info)

Serine transhydroxymethylase from rabbit liver. Sequence of anonapeptide at the pyridoxal-5'-phosphate-binding site. (2/466)

The amino acid sequence of the coenzyme-binding site of serine transhydroxymethylase from rabbit liver has been determined. After reduction with NaBH4 and aminoethylation, a first sample of enzyme was digested with thermolysin and a single phosphopyridoxyl peptide was isolated. A second sample of similarly treated enzyme was digested with chymotrypsin and three phosphopyridoxyl peptides clearly originating from a unique coenzyme-binding site were isolated. Sequence analysis of these peptides indicate the following structure: Val-Val-Thr-Thr-His(Pxy)-Thr-Leu. Sequence homologies of the active site of various pyridoxalphosphate enzymes are discussed in terms of a possible catalytic role and of evolution of this class of proteins.  (+info)

Radioactive labelling of ribosomal proteins with reductive alkylation and its use in studying ribosome-cytosol interactions. (3/466)

Mouse brain ribosomes were radioactively labelled by a cell-free reductive alkylation reaction with NaBH4 and [14C]formaldehyde. The radioactivity was largely associated with ribosomal proteins, but little, if any, of the rRNA was radioactive after the alkylation procedure. Both ribosomal structural proteins and loosely associated components were successfully labelled by this procedure. The sedimentation properties of the ribosomes were unaltered and their ability to carry out poly(U)-directed protein synthesis, although decreased, was largely retained. Incubation of 14C-labelled ribosomes with brain cytosol resulted in a 17% loss of radioactivity, although treatment of the ribosomes with 1.0 m-KCl to remove the loosely associated factors rendered the ribonucleoprotein particles resistant to cytosol effects. The ribosome-cytosol interactions did not appear to be related to an exchange process, since the released radioactivity was largely degraded to acid-soluble material. In addition, the incubation of native ribosomes with brain cytosol resulted in an almost complete loss in the ability of the ribosomes to participate in cell-free protein synthesis.  (+info)

The iron sulfur protein AtsB is required for posttranslational formation of formylglycine in the Klebsiella sulfatase. (4/466)

The catalytic residue of eukaryotic and prokaryotic sulfatases is a alpha-formylglycine. In the sulfatase of Klebsiella pneumoniae the formylglycine is generated by posttranslational oxidation of serine 72. We cloned the atsBA operon of K. pneumoniae and found that the sulfatase was expressed in inactive form in Escherichia coli transformed with the structural gene (atsA). Coexpression of the atsB gene, however, led to production of high sulfatase activity, indicating that the atsB gene product plays a posttranslational role that is essential for the sulfatase to gain its catalytic activity. This was verified after purification of the sulfatase from the periplasm of the cells. Peptide analysis of the protein expressed in the presence of AtsB revealed that half of the polypeptides carried the formylglycine at position 72, while the remaining polypeptides carried the encoded serine. The inactive sulfatase expressed in the absence of AtsB carried exclusively serine 72, demonstrating that the atsB gene is required for formylglycine modification. This gene encodes a 395-amino acid residue iron sulfur protein that has a cytosolic localization and is supposed to directly or indirectly catalyze the oxidation of the serine to formylglycine.  (+info)

Reaction centers of photosystem II with a chemically-modified pigment composition: exchange of pheophytins with 13(1)-deoxo-13(1)-hydroxy-pheophytin a. (5/466)

Isolated reaction centers of photosystem II with an altered pigment content were obtained by chemical exchange of the native pheophytin a molecules with externally added 13(1)-deoxo-13(1)-hydroxy-pheophytin a. Judged from a comparison of the absorption spectra and photochemical activities of exchanged and control reaction centers, 70-80% of the pheophytin molecules active in charge separation are replaced by 13(1)-deoxo-13(1)-hydroxy-pheophytin a after double application of the exchange procedure. The new molecule at the active branch was not active photochemically. This appears to be the first stable preparation in which a redox active chromophore of the reaction center of photosystem II was modified by chemical substitution. The data are compatible with the presence of an active and inactive branch of cofactors, as in bacterial reaction centers. Possible applications of the 13(1)-deoxo-13(1)-hydroxy-pheophytin a-exchanged preparation to the spectral and functional analysis of native reaction centers of photosystem II are discussed.  (+info)

Reactions of lipid-derived malondialdehyde with collagen. (6/466)

Malondialdehyde is a product of fatty acid oxidation (e.g. from low density lipoprotein) implicated in the damage of proteins such as collagen in the cardiovascular system (Chio, K. J., and Tappel, A. L. (1969) Biochemistry 8, 2821-2827). Its concentration is raised in diabetic subjects probably as a side effect of increased protein glycation. Collagen has enzyme-catalyzed cross-links formed between its individual molecules that are essential for maintaining the structure and flexibility of the collagen fiber. The cross-link dehydro-hydroxylysinonorleucine reacts irreversibly with 10 mM malondialdehyde at least 3 orders of magnitude faster than glucose reactions with lysine or arginine, such that there is little cross-link left after 1 h at 37 degrees C. Other cross-links and glycated elements of collagen are also vulnerable. Several possible products of malondialdehyde with collagen cross-links are proposed, and the potential involvement of collagenous histidine in these reactions is discussed. We have also isolated Ndelta-(2-pyrimidyl)-L-ornithine from collagenous arginine reacted with malondialdehyde. The yields of this product were considerably higher than those from model reactions, being approximately 2 molecules/collagen molecule after 1 day at 37 degrees C in 10 mM malondialdehyde. Collagenous lysine-derived malondialdehyde products may have been present but were not protected from protein acid hydrolysis by standard reduction techniques, thus resulting in a multitude of fragmented products.  (+info)

The immobilization of adenine nucleotides on polysaccharides by using glutaraldehyde coupling and borohydride reduction. (7/466)

Adenine nucleotides were immobilized on modified Sepharose 4B or Dextran T40 with glutaraldehyde and reduced with KBH4. Binding was dependent on pH and the nature of the amino group on the modified polysaccharide. ATP bound to soluble dextran retained coenzyme activity with glycerol kinase. Binding is proposed to occur via a Schiff base.  (+info)

Sodium borohydride is of interest as a source for a hydrogen generation during its catalytic hydrolysis. Various catalysts have been developed for this purpose. In the present study the graphene supported platinum-ruthenium-cobalt catalysts (denoted as PtRuCo/GR) with the different Pt:Ru:Co molar ratios, prepared by means of microwave-assisted synthesis, were used as catalysts towards hydrogen generation via sodium borohydride hydrolysis. The morphology and composition of catalysts were examined using Field Emission Scanning Electron Microscopy and Inductively Coupled Plasma Optical Emission Spectroscopy. Catalytic activity of PtRuCo/GR with the different Pt:Ru:Co molar ratios was determined by measuring the amount of hydrogen generated directly from aqueous alkaline solutions of sodium borohydride and compared with that of Co/GR. The data on hydrogen generation volume with respect to time at different concentrations of sodium borohydride and different temperatures have been presented. It has ...

Authors: MEVLUT SERDAR, NURHAN GÜMRÜKÇÜOĞLU, ŞENGÜL ALPAY KARAOĞLU, NESLİHAN DEMİRBAŞ Abstract: A series of acylhydrazones (2a-d) was synthesized from the reactions of iminoester hydrochlorides (1a-e) with acyl hydrazines. 2,5-Dialkyl 1,3,4-oxadiazoles (3a-d) were obtained in the same reaction media. The treatment of acylhydrazones with hydrazine hydrate afforded 4-amino-3,5-dialkyl-1,2,4-triazoles (4a-c). The acetylation of 4-amino-3-(4-hydroxyphenyl)-5-phenyl-4H-1,2,4-triazole (4a) produced 4-amino-5-(4-acetoxyphenyl)-3-phenyl-4H-1,2,4-triazole (9), while the acetylation of 4-amino-3-(4-tolyl)-5-phenyl-4H-1,2,4-triazole (4b) gave 4-acetylamino-3-phenyl-5-(4-tolyl)-4H-1,2,4-triazole (10). The treatment of compound 4b with various aromatic aldehydes or acetophenone and 4-nitroacetophenone resulted in the formation of 4-arylidenamino-3,5-dialkyl-4H-1,2,4-triazoles (5a-e and 7a,b).

Method of generating hydrogen gas from sodium borohydride (Patent) | SciTech Connect  Method of generating hydrogen gas from sodium borohydride (Patent) | SciTech Connect
A compact solid source of hydrogen gas, where the gas is generated by contacting water with micro-disperse particles of sodium borohydride in the presence of a catalyst, such as cobalt or ruthenium. The micro-disperse particles can have a substantially uniform diameter of 1-10 microns, and preferably about 3-5 microns. Ruthenium or cobalt catalytic nanoparticles can be incorporated in the micro-disperse particles of sodium borohydride, which allows a rapid and complete reaction to occur without the problems associated with caking and scaling of the surface by the reactant product sodium metaborate. A closed loop water management system can be used to recycle wastewater from a PEM fuel cell to supply water for reacting with the micro-disperse particles of sodium borohydride in a compact hydrogen gas generator. Capillary forces can wick water from a water reservoir into a packed bed of micro-disperse fuel particles, eliminating the need for using an active pump. ...

TY - JOUR. T1 - Quantitative Peptidomics with Five-plex Reductive Methylation labels. AU - Tashima, Alexandre K.. AU - Fricker, Lloyd D.. PY - 2018/5/1. Y1 - 2018/5/1. N2 - Quantitative peptidomics and proteomics often use chemical tags to covalently modify peptides with reagents that differ in the number of stable isotopes, allowing for quantitation of the relative peptide levels in the original sample based on the peak height of each isotopic form. Different chemical reagents have been used as tags for quantitative peptidomics and proteomics, and all have strengths and weaknesses. One of the simplest approaches uses formaldehyde and sodium cyanoborohydride to methylate amines, converting primary and secondary amines into tertiary amines. Up to five different isotopic forms can be generated, depending on the isotopic forms of formaldehyde and cyanoborohydride reagents, allowing for five-plex quantitation. However, the mass difference between each of these forms is only 1 Da per methyl group ...

Isomaltose oligosaccharides varying in size from two sugars, isomaltose (IM2), to seven sugars, isomaltohepatose (IM7), were coupled to stearylamine by reductive amination with sodium cyanoborohydride. Each compound was purified by column chromatography to yield a series of glycolipids containing oligosaccharides differing in length. Stearyl-isomaltotriose to stearyl-IM7 could be incorporated into liposomes and could render them agglutinable by specific antibodies to alpha 1 leads to 6 dextran and could be lysed if complement was also added, whereas those containing stearyl-IM2 were not agglutinated or lysed, indicating that stearyl-IM2 may not be protruding from the liposome surface sufficiently to react with the antibody. Stearyl-isomaltosyl oligosaccharides by themselves or incorporated into liposomes were equally antigenic when emulsified in complete Freunds adjuvant. They elicited pauciclonal responses, and the antibodies were alpha 1 leads to 6 specific, cross-reacted with dextran, and ...

Epidemiological studies have shown an association between alcohol (ethanol) consumption and increased cancer risk. The effect of alcohol consumption on the levels and persistence of N(2)-ethylidene-2-deoxyguanosine (N(2)-ethylidene-dG) formed by acetaldehyde, the oxidative metabolite of ethanol, in human leukocyte DNA was investigated. DNA was isolated from venous blood samples obtained from 30 male non-smoking individuals before consumption of alcohol (0h) and subsequently at 3-5h following the consumption of 150mL of vodka (containing 42% pure ethanol). Additional samples were collected 24h and 48h post-alcohol consumption. The levels of N(2)-ethyl-2-deoxyguanosine (N(2)-ethyl-dG) in the DNA were determined following reduction of N(2)-ethylidene-dG with sodium cyanoborohydride using a liquid chromatography-tandem mass spectrometry selected reaction monitoring method. A slight time-dependent trend showing an increase and decrease in the levels of N(2)-ethyl-dG was observed following ...

Recommendations on how to choose sodium borohydride | Linux Journal  Recommendations on how to choose sodium borohydride | Linux Journal
Sodium borohydride is a element that is a normal reducing agent. It is an organic element that has a good number of diverse uses and programs. It is very frequently used in the manufacturing and production sectors to great effect. Its visual aspect is in most cases in the form of a greyish white powder element. It may act as a fairly great reducing agent when it is compounded with water or alcohol. As it is a compound, it constantly has to be handled with great treatment as it can potentially react really in a different way when it comes into contact with distinct kinds of chemical natural ingredients. It is incompatible along with additional elements such as metal salts, and sulphuric acid. Due to the point that it are able to break down quite simply, it can usually generate acidic and serious byproducts such as hydrogen gas and sodium oxide. It definitely necessities to be treated with a right amount of care when being put into use in the producing and construction industrial sectors. As a ...

Thermodynamic stability of alkali-metal-zinc double-cation borohydrides at low temperatures  Thermodynamic stability of alkali-metal-zinc double-cation borohydrides at low temperatures
We study the thermodynamic stability at low temperatures of a series of alkali-metal-zinc double-cation borohydrides, including LiZn(BH4)(3), LiZn2(BH4)(5), NaZn(BH4)(3), NaZn2(BH4)(5), KZn(BH4)(3), and KZn2(BH4)(5). While LiZn2(BH4)(5), NaZn(BH4)(3), NaZn2(BH4)(5), and KZn(BH4)(3) were recently synthesized, LiZn(BH4)(3) and KZn2(BH4)(5) are hypothetical compounds. Using the minima-hopping method, we discover two new lowest-energy structures for NaZn(BH4)(3) and KZn2(BH4)(5) which belong to the C2/c and P2 space groups, respectively. These structures are predicted to be both thermodynamically stable and dynamically stable, implying that their existence may be possible. On the other hand, we predict that the lowest-energy P1 structure of LiZn(BH4)(3) is unstable, suggesting a possible reason elucidating why this compound has not been experimentally identified. In exploring the low-energy structures of these compounds, we find that their energetic ordering is sensitive to the inclusion of the van ...

Pt-Ru nanoparticles supported on carbon nanofibers (CNF) were synthesized by the sodium borohydride reduction method, using different generation dendrimers (zero, one, two and three generations). After the synthesis process, these materials were submitted to a heat treatment at 350 °C, in order to clean the nanoparticle surface of organic residues. TEM characterization showed that the Pt-Ru nanoparticles size ranged between 1.9 and 5.5 nm. The use of dendrimers did not totally avoid the formation of aggregates, although monodisperse sizes were observed. The heat treatment produces the desired surface cleaning, although promoted the formation of agglomerates and crystalline Ru oxides. The study of the electrochemical activity towards the methanol oxidation displayed some clues about the influence of both the dendrimer generation and the presence of Ru oxides. Moreover, the apparent activation energy Eap for this reaction was determined. The results showed a beneficial effect of the heat treatment on the

Haem a with denatured proteins in strongly alkaline solutions forms haemochromes whose α-absorption bands lie 15 to 20 mμ more towards shorter wavelengths than those of haemochromes with other nitrogenous ligands. It is found that this is due to the formation of Schiffs bases, the formyl side chain of haem a being condensed with amino groups of the protein. The same reaction is given by other haems and porphyrins with formyl side chains. The Schiffs bases are stable only at high pH and are dissociated at pH 7 to 8. Schiffs bases with methylamine are also obtained with high concentration of methylamine at high pH. These compounds are compared with alkaline indicator yellow (retinal-opsin) and retinylidene methylamine. ...

Glucose can react non-enzymatically with amino groups of, for example, proteins, to yield derivatives termed advanced glycation end products (AGE), which contribute to many chronic progressive diseases associated with microvascular complications. The study aimed to determine the effect of AGE-modified albumin on THP-1 cells and human monocyte-derived macrophages. Bovine serum albumin (BSA) or human serum albumin (HSA), modified by glucose-derived AGE, was prepared by incubation with glucose for differing periods of time. Alternatively, BSA was incubated with sodium cyanoborohydride and glyoxylic acid to produce N(epsilon)-(carboxymethyl)lysine-modified BSA (CML-BSA). Stimulation for 24h of THP-1 cells with BSA, incubated for 6-8 weeks with glucose, induced significant VEGF release. Human monocyte-derived macrophages stimulated with extensively glycated HSA also showed significant VEGF release, as well as upregulation of IL-8 production, incubation for 6h with extensively glycated HSA increased release

Structural investigations on the lignin-carbohydrate complexes of Lolium perenne | Biochemical Journal  Structural investigations on the lignin-carbohydrate complexes of Lolium perenne | Biochemical Journal
1. Lignin-carbohydrate complexes isolated from leaf blade, leaf sheath and stem tissue of ryegrass by extraction with dimethyl sulphoxide were examined by fractionation procedures. Although the complexes are heterogeneous, heterogeneity is shown only in the ratio of the individual monosaccharide residues and not in the ratio of lignin to carbohydrate. 2. The molecular weight of the complexes is high (≥150000), but chemical modification by alkaline hydrolysis, borohydride reduction or lead tetra-acetate oxidation does not drastically decrease it. Low-molecular-weight fragments released by alkaline treatment were shown to contain acetic acid, ferulic acid and p-coumaric acid. 3. On the basis of the chemical stability of the complexes, it is postulated that at least three types of bonding may be present between lignin and carbohydrate, namely one cleaved on borohydride reduction, another cleaved by alkali and a linkage resistant to alkali. 4. The carbohydrate portion of the complexes is composed ...

Reduction of ketones [NaBH4] - ChemistryScore  Reduction of ketones [NaBH4] - ChemistryScore
Reduction, in organic chemistry, means the addition of hydrogen to molecule or removal of electronegative atoms such as halogen or oxygen from the molecule.. Hydride, by itself, is not a good nucleophile because it is not polarizable. But sodium borohydride, NaBH4 function as a delivery agent of nucleophilic hydride anion. And the solvent function as the source of a proton. The solvent can be ethanol, methanol, or water.. In this medium, the reagent donates hydride to the carbonyl carbon with simultaneous protonation of the carbonyl oxygen by the solvent. The intermediate which is obtained by first transferring of the hydride ion can attack three more carbonyl substrates until all the hydride atoms of the original reagent have been used up. Thus one equivalent of borohydride is capable of reducing four equivalents of a ketone to a secondary alcohol.. ...

Pectin was modified by oxidation with sodium periodate at molar ratios of 2.5, 5, 10, 15 and 20 mol% and reductive amination with tyramine and sodium cyanoborohydride afterwards. Concentration of tyramine groups within modified pectin ranged from 54.5 to 538 μmol/g of dry pectin while concentration of ionizable groups ranged from 3.0 to 4.0 mmol/g of dry polymer compared to 1.5 mmol/g before modification due to the introduction of amino group. All tyramine-pectins showed exceptional gelling properties and could form hydrogel both by cross-linking of carboxyl groups with calcium or by cross-linking phenol groups with peroxidase in the presence of hydrogen peroxide. These hydrogels were tested as carriers for soybean hull peroxidase (SHP) immobilization within microbeads formed in an emulsion based enzymatic polymerization reaction. SHP immobilized within tyramine-pectin microbeads had an increased thermal and organic solvent stability compared to the soluble enzyme. Immobilized SHP was more active in

Reductions with metal alkoxyaluminium hydrides - Wikipedia  Reductions with metal alkoxyaluminium hydrides - Wikipedia
Reductions with metal alkoxyaluminium hydrides are chemical reactions that involve either the net hydrogenation of an unsaturated compound or the replacement of a reducible functional group with hydrogen by metal alkoxyaluminium hydride reagents. Sodium borohydride and lithium aluminium hydride are commonly used for the reduction of organic compounds. These two reagents are on the extremes of reactivity-whereas lithium aluminium hydride reacts with nearly all reducible functional groups, sodium borohydride reacts with a much more limited range of functional groups. Diminished or enhanced reactivity may be realized by the replacement of one or more of the hydrogens in these reagents with alkoxy groups. Additionally, substitution of hydrogen for chiral alkoxy groups in these reagents enables asymmetric reductions. Although methods involving stoichiometric amounts of chiral metal hydrides have been supplanted in modern times by enantioselective catalytic reductions, they are of historical interest ...

Mixed-anion and mixed-cation borohydride KZn(BH4)Cl2: Synthesis, structure and thermal decomposition | DIAL.pr - BOREAL  Mixed-anion and mixed-cation borohydride KZn(BH4)Cl2: Synthesis, structure and thermal decomposition | DIAL.pr - BOREAL
KZn(BH4)Cl2, synthesized for the first time, contains a heteroleptic complex anion [Zn(BH4)Cl2]-, extending the structural diversity of metal borohydrides. In-situ synchrotron powder diffraction, NMR and Raman spectroscopy were used to characterize KZn(BH4)Cl2 and to evaluate the mechanism, for its thermal decomposition. The title compound decomposes at a significantly lower temperature than KBH4 and may be used for inspiration for the design of novel hydrogen storage materials. Combining different ligands in modified metal borohydrides is proposed as a way to adjust stability with respect to hydrogen, desorption. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA. ...

Cell culture and animal studies for intracerebral delivery of borocaptate in liposomal formulation. - Semantic Scholar  Cell culture and animal studies for intracerebral delivery of borocaptate in liposomal formulation. - Semantic Scholar
The efficacy of a liposomal formulation for intracerebral delivery of borocaptate (BSH) to brain tumor cells has been investigated using cell culture to study BSH uptake and persistence and using tumor-bearing rats to determine BSH distribution in the brain. During a 16-hr incubation, cellular uptake of BSH solution or BSH liposomal formulation was similar. However, the cellular persistence of BSH greatly increased when BSH was present in liposome. The differences in cellular persistence for BSH solution and BSH-loaded liposomes were significant both in 12-hr and 24-hr incubation experiments (p | 0.05 and p | 0.01, respectively). For the studies involving tumor-bearing rats, BSH level in tumor tissue was significantly higher than that in normal brain tissue at 2 hr and 6 hr after intracerebral injection of BSH-loaded liposomes (p | 0.01). Our study indicated that the liposomal formulation enhanced cellular persistence of BSH in tumor cells and therefore favored the boron accumulation in the cells. With

This unit describes release of oligosaccharides that are attached to polypeptides through an N-acetylgalactosamine (GalNAc) linkage to the hydroxyl groups of serine or threonine. The b-elimination procedures described here can be used to recover the oligosaccharide chains (also called glycans) and/or identify the serine or threonine residues involved in the linkage. A b-elimination method employing sodium borohydride (NaBH4) and alkaline conditions is described, and an alternative method is also presented in which only alkaline conditions are used without a reducing agent. Another alternative protocol uses sodium sulfite. ...

Fast and efficient method for reduction of carbonyl compounds with NaBH4 /wet SiO2 under solvent free condition  Fast and efficient method for reduction of carbonyl compounds with NaBH4 /wet SiO2 under solvent free condition
Synthetic utilities of vicinal diols are well known and their preparations from reduction of a-diketones and acyloins have attracted a great deal of attention. In this context, we decided to examine solid state reduction of a-diketones and acyloins with NaBH4 in the presence of wet SiO2. Reduction of a-diketones to their vicinal diols took place by 1.5 molar equivalents of NaBH4 in the presence of wet SiO2 (30% m/m) under solvent free condition at 75-80 ºC. The product diols were obtained in excellent yields and all attempts to reduce a-diketones into acyloins were unsatisfactory by this reducing system (Table 7). Reduction of acyloins to vicinal diols was also achieved successfully by NaBH4/wet SiO2 (30% m/m) in solid state. Using one molar equivalent of NaBH4 at 75-80 ºC was the requirement for the excellent yields of the corresponding products (Table 7). No assumptions on the simple diastereoselectivity (syn or anti) of the products were made.. The influence of water in wet SiO2 for the ...

Biotage - A Seminal Supported Resin for Reductive Amination  Biotage - A Seminal Supported Resin for Reductive Amination
Sodium triacetoxyborohydride has emerged as one of the reagents used most frequently for carrying out reductive amination of carbonyl compounds, a reaction that is also known as reductive alkylation of amines. A disadvantage of sodium triacetoxyborohydride is its poor solubility, and that product isolation requires an aqueous quench followed by liquid-liquid extraction and column chromatography.. Biotage® MP-Triacetoxyborohydride was developed to perform in a manner similar to that of sodium triacetoxyborohydride, while simplifying reagent handling and product purification. Moreover, for many of these reactions, a scavenger resin may be added for one-pot purification of the product.. ...

Immunocytochemistry. Eleven naive adult male Sprague Dawley rats were anesthetized deeply and perfused transcardially with 10 ml of heparin saline (1000 U/ml), followed by fixative. For 10 rats, the fixative consisted of 50 ml of 3.75% acrolein and 2% paraformaldehyde in 0.1 m phosphate buffer, pH 7.4 (PB), followed by 250 ml of 2% paraformaldehyde. To determine whether the degree of DAT immunostaining was dependent on the fixative that was used, we perfused the remaining animal with 500 ml of 4% paraformaldehyde with 0.2% glutaraldehyde. The brains were removed, post-fixed in the final fixative for 30 min, and sectioned at 50 μm on a vibratome. To improve antigenicity and reduce nonspecific immunolabeling, we subsequently treated the sections for 30 min with 1% sodium borohydride (Leranth and Pickel, 1989) and rinsed them in PB. To reduce further the nonspecific labeling before incubation in primary antibody, we treated sections for 30 min in a blocking solution consisting of 1% bovine serum ...

Parametric study of the influence of heterogeneous boron concentration and coolant density on cross section generation in BWRs  Parametric study of the influence of heterogeneous boron concentration and coolant density on cross section generation in BWRs
In this paper, we investigate the effect of heterogeneous boron concentration and coolant density distribution on nodal macroscopic cross sections, which could potentially arise in an Anticipated Transient Without Control rods of a boiling water reactor. All calculations are made with the 2-D transport code PHOENIX4. Full core simulators, such as POLCA7, often have simple models for handling such heterogeneities with the basic requirement that conservative results are obtained simulating such core conditions. We have found that this is not always the case and that the errors can potentially be quite high.

FAO GIEWS Country Brief on Bangladesh  FAO GIEWS Country Brief on Bangladesh
Harvesting of the 2017 almost entirely irrigated "boro" paddy crop, accounting for some 55 percent of annual output, will be completed in June. Adequate irrigation water supplies and favourable weather conditions benefitted "boro" paddy development this season, although excess precipitation in late March and early April triggered localized flooding over northeastern producing areas. The inundations occurred just before harvest time, impacting crops in Sylhet, Dhaka and Mymensingh divisions in particular.. Planting of the minor "aus" paddy crop, which accounts for 7 percent of annual output, is currently ongoing and will be followed by the June start of "aman" plantings. Assuming normal growing conditions prevail, early prospects for these crops are favourable, on anticipation that attractive paddy prices will stimulate increases in plantings. As a result and pending assessments of "boro" damages incurred, FAO tentatively forecasts aggregate 2017 paddy production at 53.1 million tonnes, 1 percent ...

N-Phenethyl-4-piperidinone - Wikipedia  N-Phenethyl-4-piperidinone - Wikipedia
N-Phenethyl-4-piperidinone (NPP) is a derivative of 4-piperidinone with the molecular formula C13H17NO. 4-Piperidinone is used as an intermediate in the manufacture of chemicals and pharmaceutical drugs such as fentanyl. Because of its possible use in the illicit manufacture of fentanyl, NPP was placed onto the list of controlled chemicals in the USA in 2007, and possession and sales of this compound are now restricted. N-Phenethyl-4-piperidinone can be prepared from 4-piperidinone and phenethyl bromide in biphasic conditions with a variety of phase transfer catalysts.[citation needed] N-Phenethyl-4-piperidinone is useful in the synthesis of pharmaceuticals, primarily fentanyl and its analogs. Paul Janssen (founder of Janssen Pharmaceutica) first synthesized fentanyl in 1960 from NPP. Janssens synthesis involved reacting N-Phenethyl-4-piperidinone with aniline, and then reducing the imine product with sodium borohydride to 4-anilino-N-phenethylpiperidine (ANPP). This product is reacted with ...

Prof. Sesha S. Srinivasan of Tuskegee University kindly suggested that we offer Magnesium Borohydride (Aldrich Prod. No. 715247) as a material for alternative energy applications.1 This complex metal hydride, produced by Aldrich Materials Science R&D, is a base-material for advanced energy storage systems with potential for fulfilling the United States Department of Energys hydrogen storage goals.2 Magnesium borohydride crystallizes in a hexagonal phase that is stable at room temperature. At 185 °C, the material converts to an orthorhombic phase, which persists and is stable upon cooling back to room temperature. Both phases consist of complex networks of cornersharing tetrahedra including a central Mg atom and four BH4 units.3. back to top. ...

Another issue that generated fear over the fate of the property is the conflict of interest between the Environmental Commission and the Boros leadership. The chair of the Environmental Commission, Harry Allen, is none other than the husband of the mayor. He has refused to recuse himself on the matter, despite his wifes documented position in favor of building on the property. In accordance with this, the department has objected to repeated attempts from concerned citizens to do their jobs and conduct environmental studies on the property. Fearing the possibility of finding something that would spur development from the area, the commission has elected to ignore this issue entirely. The mayor has gone on record claiming that the boro was denied a grant and therefore cannot do any studies. This is wildly untrue though, as the state environmental commission provides guidelines on how volunteers can conduct the studies themselves. No grant money needed ...

A new target concept termed Discs Incorporating Sector Configured Orbiting Sources (DISCOS), is proposed for spallation applications, including BNCT (Boron Neutron Capture Therapy). In the BNCT application a proton beam impacts a sequence of ultra thin lithium DISCOS targets to generate neutrons by the {sup 7}Li(p,n){sup 7}Be reaction. The proton beam loses only a few keV of its {approximately}MeV energy as it passes through a given target, and is re-accelerated to its initial energy, by a DC electric field between the targets.

Boron neutron capture therapy, or BNCT, is a two-part therapy that enhances the effect of radiation on cancer cells while minimizing the effect on nearby healthy cells.. Inadvertant damage to non-cancerous tissue is a major side effect of conventional radiation therapies, especially in the treatment of brain tumors. Conventional radiation therapy also requires several bouts of treatment, an inconvenience for many patients.. BNCT avoids these pitfalls by using radiation from BNLs medical reactor and a drug containing the element boron. Called BPA for boronophenylalanine, the drug is injected into the patient and travels through the bloodstream, concentrating preferentially in tumor tissue.. By itself BPA is harmless, but when exposed to a beam of neutrons from the reactor, the boron atoms capture neutrons, creating secondary effects that kill cells in the immediate vicinity.. Clinical trials of BNCT have been under way at BNL since 1994. Other locations in the U.S. are conducting related ...

For years, radiotherapy has been an essential mode of noninvasive cancer therapy and advancements have led to life saving treatments for patients. In contrast to other conventional radiotherapies, boron neutron capture therapy (BNCT) is unique in its selective destruction of cancerous cells. BNCT is based on nuclear capture and fission reactions when nonradioactive 10B is irradiated with neutrons to yield excited 11B* which decays into high energy alpha particles and 7Li nuclei. Boron is preferentially accumulated into tumour cells though non-toxic carriers and the short length of the generated neutron beams (5-9 µm) destroys nearby cells leaving the surrounding healthy tissue intact.. The development of carrier systems that deliver sufficient amounts of boron to carry out effective destruction of all vicinal tumour cells has been a significant area of BNCT research for many years. A recent breakthrough made by Professors Atsushi Ikeda of Hiroshima University, Takeshi Nagasaki of Osaka City ...

TY - GEN. T1 - Ammonium borohydride. T2 - Solid hydrogen storage material with highest gravimetric hydrogen content. AU - Karkamkar, Abhi. AU - Heldebrant, David J.. AU - Linehan, John. AU - Autrey, Tom. PY - 2009. Y1 - 2009. N2 - Various options for hydrogen storage are being studied ranging gases (hydrogen), liquids (e.g., methanol) to solids (e.g., lithium borohydride, boranes and amides). However, no single material today meets all the required technical targets. Here we report the synthesis, structure and hydrogen desorption properties of a unique hydrogen storage material, i.e., one that stores hydrogen on both the cation and anion, ammonium borohydride. Further we show the compound releases greater than 20 wt% hydrogen in three steps at temperatures less than 180 °C and provide evidence that NH4BH4 crystallizes at room temperature and standard pressure in a rock-salt structure. The experimental lattice parameters provide an estimate of the volumetric density, ca. 154 g Hydrogen/liter of ...

USE OF BORIC ACID IN BORON NEUTRON CAPTURE THERAPY FOR LIVER CANCER - Patent application  USE OF BORIC ACID IN BORON NEUTRON CAPTURE THERAPY FOR LIVER CANCER - Patent application
0030] When the FDA-approved 10B-BPA is used as a boron drug in the BNCT for treating tumors, the ratio of boron concentrations accumulated in the tumor and the adjacent to normal organs must be evaluated by using 18F-BPA Positron Emission Tomography (PET) first. In other words, if a boron drug that is similar to 10B-BPA (high T/N ratio) is developed for use in the BNCT for treating liver cancer, this step of labeling the boron drug with radioisotope (such as 18F) and evaluating the boron drug T/N ratio by PET cannot be avoided. But in the present invention, boric acid is used as a boron drug in the BNCT for treating liver cancer, which does not require the step of labeling the boron drug with radioisotope or evaluating the boron drug T/N ratio by PET. This is due to the fact that boric acid does not result in specific accumulation in the soft tissues of a living creature, so the boron concentrations in a patients blood and in the liver tumor are approximately equal. Consequently, it is not ...

Effect of Low Temperature on Chlorophyll and Carotenoid Content on the Seedlings of Some Selected Boro Rice Varieties  Effect of Low Temperature on Chlorophyll and Carotenoid Content on the Seedlings of Some Selected Boro Rice Varieties
A study was conducted to screen out the low-temperature tolerant Boro rice seedlings from November 2012 to January 2013 for facing the upcoming rice production challenge in Northwest Bangladesh. The experimental time was characterized by a prevailing low environmental temperature of below 15°C. Five rice cultivars (V1: BR-2; V2: BR-16; V3: Pariza; V4: Minicate; V5: BRRI dhan 50) were selected for the study. The leaf proline, chlorophyll content and total carotenoid content were investigated. The V2 (BR-16) seedling synthesized the higher leaf proline (1.228 g·g-1) at a low temperature than those of other tested cultivars. Again, the highest amount of chlorophyll-a (3.957 g·g-1), chlorophyll-b (2.118 g·g-1), chlorophyll-a/b ratio (3.6754 mg·g-1) and total chlorophyll (5.051 g·g-1) was measured in V2 (BR-16). The maximum total carotenoid (1.213 g·g-1) was also observed in V2. In this experiment, the V2 (BR-16) showed comparatively better potentiality to survive at low temperatures (below 15°C)

PtSnCo/C Anode Catalyst for Methanol Oxidation  PtSnCo/C Anode Catalyst for Methanol Oxidation
Abstract: A binary metallic catalyst (PtSn/C) and a ternary metallic catalyst (PtSnCo/C) with a metal mass fraction of 20% were prepared by borohydride reduction and subsequent hydrothermal treatment in a glycol liquid phase. The structure and composition of the as-prepared electrocatalysts were characterized by X-ray diffraction (XRD) and energy-dispersive spectrometry (EDS). Their activity and stability for the catalysis of methanol oxidation were evaluated by anodic linear sweep voltammetry (LSV), cyclic voltammetry (CV), and the anodic stripping of a pre-adsorbed CO monolayer. We found that the PtSnCo/C catalyst gave the best catalytic activity for the methanol oxidation of all the catalysts including the commercial JM-PtRu/C catalyst. After 100 cycles, the peak current of methanol oxidation for the PtSn/C catalyst rapidly decreased to 11% of its initial peak current but PtSnCo/C decreased to only 50%. This result suggests that the PtSnCo/C catalyst has better chemical stability for the ...

  • When the borohydride complex is volatile, this decomposition pathway is the basis of chemical vapor deposition, a way of depositing thin films of metal borides. (wikipedia.org)
  • The decomposition temperature of tetra-n-butylammonium borohydride semiclathrate was measured at 5.7 °C, which is higher than that for pure THF hydrate (4.4 °C). The present results reveal that the BH4− anion is capable of stabilizing tetraalkylammonium hydrates. (mendeley.com)
  • Using \textit{ab-initio} studies based on the density-functional theory, we have calculated binding energies per hydrogen molecule for decomposition reactions of transition metal borohydrides \textit{MH}$_{x}B_{12}H_{12}$ to \textit{MB}$_{12}$ structures, where $M$ corresponds to Sc\textit{, Ti, or V}. Depending on the valence of the transition metal, $x$ can be 1$, 2$, or $3. (aps.org)

  • In metal complexes, the borohydride ion is bound to the metal by means of bridging hydrogen atoms, usually in one of three different ways: monodentate (one hydrogen bridge), bidentate (two hydrogen bridges), and tridentate (three hydrogen bridges) (η1, η2, or η3). (wikipedia.org)
  • Because of their high hydrogen content, borohydride complexes and salts have been of interest in the context of hydrogen storage. (wikipedia.org)
  • The cooperative reducing capability of the two UIII centres now enforced by the large and relatively flexible macrocycle is compared for the two complexes, recognising that the borohydrides can provide additional reducing capability, and that the aryloxide-capped 2-K is constrained to reactions within the cleft.
