Efficient nitroso group transfer from N-nitrosoindoles to nucleotides and 2'-deoxyguanosine at physiological pH. A new pathway for N-nitrosocompounds to exert genotoxicity. (1/350)

The endogenous formation of N-nitrosoindoles is of concern since humans are exposed to a variety of naturally occurring and synthetic indolic compounds. As part of a study to evaluate the genotoxicity of N-nitrosoindoles, the reactions of three model compounds with purine nucleotides and 2'-deoxyguanosine at physiological pH were investigated. The profiles of reaction products were identical for each of the N-nitrosoindoles and three distinct pathways of reaction could be discerned. These pathways were: (i) depurination to the corresponding purine bases, (ii) deamination, coupled with depurination, to give hypoxanthine and xanthine, and (iii) formation of the novel nucleotide 2'-deoxyoxanosine monophosphate and its corresponding depurination product oxanine in reactions with 2'-deoxyguanosine monophosphate. 2'-Deoxyoxanosine and oxanine were observed in reactions with 2'-deoxyguanosine. Further studies showed that formation of all of these products could be rationalized by an initial transnitrosation step. These results suggest that, in contrast to many other genotoxic N-nitrosocompounds which are known to alkylate DNA, the genotoxicity of N-nitrosoindoles is likely to arise through transfer of the nitroso group to nucleophilic sites on the purine bases. All of the products resulting from transnitrosation by N-nitrosoindoles are potentially mutagenic. These findings reveal a new pathway for N-nitrosocompounds to exert genotoxicity.  (+info)

Studies of structure and mechanism in acetonitrile chemical ionization tandem mass spectrometry of polyunsaturated fatty acid methyl esters. (2/350)

Recently it has been shown that acetonitrile chemical ionization tandem mass spectrometry (CI-MS/MS) is a rapid, on-line means to determine double bond position in fatty acid methyl esters (FAME). The mechanism of this gas phase condensation reaction has been studied. Evidence of the (1-methyleneimino)-1-ethenylium ion (m/z 54), formed upon the reaction of acetonitrile with itself, adding across the double bond in a [2 + 2] cycloaddition reaction is observed. When this nascent complex undergoes collision-induced dissociation, two diagnostic ions emerge. One of these ions results from loss of the hydrocarbon end of the FAME, whereas the other ion results from loss of the methyl ester end, and when considered together, the diagnostic ions localize the positions of the double bonds in the FAME. Several labeling and MS/MS/MS experiments on the two diagnostic ions were performed to determine a plausible fragmentation mechanism of the stable (1-methyleneimino)-1-ethenylium-FAME complex. The first generation product ions, or diagnostic ions, appear to be formed though a charge-driven mechanism, whereas the second generation product ions are formed via charge-remote fragmentations. Plausible mechanisms for the formation and subsequent dissociation of the diagnostic ions are presented for the monounsaturated, diunsaturated, and polyunsaturated (3 or more double bonds) FAME.  (+info)

Stimulation of tolbutamide hydroxylation by acetone and acetonitrile in human liver microsomes and in a cytochrome P-450 2C9-reconstituted system. (3/350)

Organic solvents are often used to solubilize lipophilic new chemical entities before their addition to in vitro test systems such as microsomal stability or cytochrome P-450 (CYP) inhibition. However, the effect of these organic solvents on the test systems is not usually characterized. This study was initiated to evaluate the effect of acetonitrile and acetone, in addition to other organic solvents, on the tolbutamide hydroxylation activity of CYP2C9 in both human liver microsomes and a CYP2C9-reconstituted system. Both acetonitrile and acetone significantly stimulated the NADPH-dependent tolbutamide hydroxylation by nearly 2- to 3-fold in human liver microsomes and CYP2C9-reconstituted system when incubated at 2 and 4% final solvent concentrations. When cumene hydroperoxide was used instead of NADPH, both acetone and acetonitrile significantly inhibited tolbutamide hydroxylation. This NADPH-dependent stimulatory effect was further evaluated by examining the effect of a series of other organic solvents with different carbon chain lengths and various functional groups, including hydroxyl, ketone, and aldehyde. Unlike acetone, two other ketone-containing solvents, methyl ethyl ketone (2-butanone) and diethyl ketone (3-pentanone) failed to significantly enhance tolbutamide hydroxylation. Other solvents tested, including methanol, ethanol, propanol, 1-butanol, 2-butanol, 1-pentanol, 2-pentanol, acetaldehyde, and dimethyl sulfoxide significantly inhibited NADPH-dependent tolbutamide hydroxylation. Overall, the stimulatory effect of both acetonitrile and acetone on tolbutamide hydroxylation was found to be primarily due to a consistent increase in V(max), whereas K(m) was unchanged in both human liver microsomes and the reconstituted CYP2C9 system. These data suggest that acetone and acetonitrile stimulate NADPH-mediated tolbutamide hydroxylation via the CYP reductase and not by modifying the affinity of tolbutamide for the CYP2C9 enzyme.  (+info)

Substrate-dependent effect of acetonitrile on human liver microsomal cytochrome P450 2C9 (CYP2C9) activity. (4/350)

Acetonitrile is an organic solvent commonly used to increase the solubility of lipophilic substrates for in vitro studies. In this study, we examined its effect on four reactions (diclofenac hydroxylation, tolbutamide methyl hydroxylation, phenytoin hydroxylation, and celecoxib methyl hydroxylation) catalyzed by human liver microsomes and by the recombinant CYP2C9. In both cases, the effect of acetonitrile on activity was found to be substrate-dependent. Namely, it increased diclofenac 4'-hydroxylase and tolbutamide methyl hydroxylase activities, but decreased celecoxib methyl hydroxylase activity in a concentration-dependent manner. By comparison, hydroxylation of phenytoin was resistant to its effect. The presence of acetonitrile (3%, v/v) gave rise to a lower K(m) and a higher V(max) for diclofenac hydroxylase in both liver microsomes and recombinant CYP2C9 preparations (87 and 52% increase in V(max)/K(m) ratio, respectively). On the other hand, the inhibitory effect of the solvent (1%, v/v) toward celecoxib hydroxylase was characterized by a decrease in V(max) (human liver microsomes) or a change in both K(m) and V(max) (rCYP2C9), leading to 25 and 46% decrease in V(max)/K(m) for both systems. The results of this study underscore the need for careful evaluation of solvent effects before initiation of inhibition or cytochrome P450 reaction phenotyping studies.  (+info)

High-throughput method development approaches for bioanalytical mass spectrometry. (5/350)

A rational approach to the development and optimization of solid-phase extraction (SPE) methods is described. The semiautomated scheme allows for the simultaneous testing of multiple chemistries using a custom multiple-sorbent 96-well method development plate. Optimized extraction conditions for up to five analytes are determined in a single 2.5-h experiment. The experiment can be tailored to determine SPE conditions (including wash protocols) for related analytes. Data obtained by liquid chromatography-atmospheric pressure ionization-mass spectrometry allows the quantitation of absolute recovery and selection of the best extraction conditions for approximately 100 analytes of diverse structure. Optimized extraction protocols yielding at least 80% recovery are determined for 81% of the analytes. For 96% of the analytes screened, extraction conditions resulting in recoveries of > or = 60% are determined. The most generic set of SPE conditions consist of either C8 or C18 sorbent with an eluent composition of acetonitrile with 5mM nitric acid added.  (+info)

High-performance liquid chromatographic determination of amphotericin B in a liposomal pharmaceutical product and validation of the assay. (6/350)

A validated high-performance liquid chromatographic method is presented to quantitate amphotericin B (AB) in a liposomal pharmaceutical formulation. The analysis is based on the chromatographic separation of AB and 1-amino-4-nitronaphthalene (the internal standard) on a C18 muBondapac reversed-phase column with a mobile phase consisting of a mixture of acetonitrile and 0.02 M ethylenediamine tetra-acetic acid disodium salt at pH 5.0 (45:55, v/v). The chromatographic analysis time is less than 10 min, and the validation of the assay shows that it is selective, accurate, and linear for the concentration range of 2.50 to 7.50 microg/mL with a detection limit of 0.00500 microg/mL. The within-day and between-day relative standard deviation values are 1.26% (n = 18) and 1.25% (n = 8), respectively. The method described conforms to the validation of compendial methods used for finished pharmaceutical products in general and offers a reliable, quick, and cost-effective procedure for examining the consistency or quality-control analysis of AB in liposomal products. It can also be applied for the determination of AB in other nonliposomal lipid-based drug delivery systems that are on the market.  (+info)

Simultaneous determination of sweeteners and preservatives in preserved fruits by micellar electrokinetic capillary chromatography. (7/350)

A micellar electrokinetic capillary method for the simultaneous determination of the sweeteners dulcin, aspartame, saccharin, and acesulfame-K and the preservatives sorbic acid; benzoic acid; sodium dehydroacetate; and methyl-, ethyl-, propyl-, isopropyl-, butyl-, and isobutyl-p-hydroxybenzoate in preserved fruits is developed. These additives are ion-paired and extracted using sonication followed by solid-phase extraction from the sample. Separation is achieved using a 57-cm fused-silica capillary with a buffer comprised of 0.05 M sodium deoxycholate, 0.02 M borate-phosphate buffer (pH 8.6), and 5% acetonitrile, and the wavelength for detection is 214 nm. The average recovery rate for all sweeteners and preservatives is approximately 90% with good reproducibility, and the detection limits range from 10 to 25 microg/g. Fifty preserved fruit samples are analyzed for the content of sweeteners and preservatives. The sweeteners found in 28 samples was aspartame (0.17-11.59 g/kg) or saccharin (0.09-5.64 g/kg). Benzoic acid (0.02-1.72 g/kg) and sorbic acid (0.27-1.15 g/kg) were found as preservatives in 29 samples.  (+info)

Lactobacillus arizonensis sp. nov., isolated from jojoba meal. (8/350)

Five strains of simmondsin-degrading, lactic-acid-producing bacteria were isolated from fermented jojoba meal. These isolates were facultatively anaerobic, gram-positive, non-motile, non-spore-forming, homofermentative, rod-shaped organisms. They grew singly and in short chains, produced lactic acid but no gas from glucose, and did not exhibit catalase activity. Growth occurred at 15 and 45 degrees C. All strains fermented cellobiose, D-fructose, D-galactose, D-glucose, lactose, maltose, D-mannitol, D-mannose, melibiose, D-ribose, salicin, D-sorbitol, sucrose and trehalose. Some strains fermented L-(-)-arabinose and L-rhamnose. D-Xylose was not fermented and starch was not hydrolysed. The mean G+C content of the DNA was 48 mol%. Phylogenetic analyses of 16S rDNA established that the isolates were members of the genus Lactobacillus. DNA reassociation of 45% or less was obtained between the new isolates and the reference strains of species with G+C contents of about 48 mol%. The isolates were differentiated from other homofermentative Lactobacillus spp. on the basis of 16S rDNA sequence divergence, DNA relatedness, stereoisomerism of the lactic acid produced, growth temperature and carbohydrate fermentation. The data support the conclusion that these organisms represent strains of a new species, for which the name Lactobacillus arizonensis is proposed. The type strain of L. arizonensis is NRRL B-14768T (= DSM 13273T).  (+info)

N2 - Examination of some trends and differences between acetonitrile/water and methanol/water mixtures has been carried out. These systems are of interest for chromatographers since they are common mobile constituents. Some differences in the molecular arrangement of these solvents were observed from NMR and IR results. These observations might be of use in understanding and developing chromatographic separations. IR studies revealed C-H bond compression in methanol compared with acetonitrile which indicates different molecular arrangement in their aqueous mixtures. NMR and IR results show a clear non-linear behaviour in molecular arrangement. This justifies the deviation of methanol and acetonitrile aqueous solution from the norm. However, both solvents showed similar ionization suppression effects on ...

Acetonitrile (also called methyl cyanide, ethanenitrile, ethyl nitrile, etc.) is the simplest organic nitrile with the molecular formula of C2H3N. It is a clear, flammable liquid, melting and boiling at -45°C and 82°C respectively. Acetonitrile is miscible with water and with common organic solvents, but immiscible with many saturated hydrocarbons (alkanes).. Acetonitrile is produced by dehydration of acetamide or by the reaction of ethanol and ammonia in the presence of catalyst such as Ag, Cu, MoO3, and ZnS at moderate temperatures as well as a by-product from the manufacture of acrylonitrile. Acetonitrile can also obtained by the reaction of cyanogen chloride with methane, ketones, ethanol, alkylene epoxides, and paraffins.. Acetonitrile finds its greatest use as an extractive distillation solvent in the petrochemical industry for separating olefin-diolefin mixtures and for C4-hydrocarbons.. It is widely used in battery applications because of its relatively high dielectric constant and ...

Absorption Quantitative data are not available for absorption of acetonitrile from the gastrointestinal or respiratory tract, although sufficient absorption can occur to induce systemic toxicity as evidenced by animal and human toxicity data. The dermal absorption of acetonitrile has been studied quantitatively. In a guideline (OECD 428 equivalent) and GLP study conducted by Haskell Laboratories (2005), the in vitro absorption of acetonitrile through human cadaver skin was shown to be low. The permeability coefficient was calculated to be 1.82 x 10-4cm/h. Short-term penetration rates were calculated to be 375.6 μg equiv/cm2/h (10 minute exposure) and 66.0 μg equiv/cm2/h (60 minute exposure). The majority of an infinite dose of acetonitrile was removed from the skin surface at the end of the 8-hour exposure, and only a small portion penetrated the skin and was recovered in the receptor fluid (0.24%). Following a 10- and 60-minute exposure, a major portion of a finite dose was recovered in the ...

TY - JOUR. T1 - Desalting electroeluted proteins with hydrophilic interaction chromatography. AU - Jeno, P.. AU - Scherer, P. E.. AU - Manningkrieg, U.. AU - Horst, M.. PY - 1993/12. Y1 - 1993/12. N2 - We describe a chromatographic procedure for the removal of sodium dodecyl sulfate (SDS) from proteins isolated by electroelution. It involves chromatography of electroeluates on poly(2-hydroxyethyl-aspartamide) silica, a support initially developed for hydrophilic interaction chromatography. The electroeluate, dialyzed against ammonium bicarbonate-SDS buffer, is directly injected onto the column, which is equilibrated in an n-propanol concentration greater than 60%. Bound proteins are eluted with a gradient of decreasing n-propanol. This procedure removes essentially all of the Coomassie blue-related contaminants and separates SDS from the protein. Due to the use of volatile buffer systems, the proteins are recovered in completely salt-free form, which facilitates further protein manipulation. ...
Examination of some trends and differences between acetonitrile/water and methanol/water mixtures has been carried out. These systems are of interest for chromatographers since they are common mobile constituents. Some differences in the molecular arrangement of these solvents were observed from NMR and IR results. These observations might be of use in understanding and developing chromatographic separations. IR studies revealed C-H bond compression in methanol compared with acetonitrile which indicates different molecular arrangement in their aqueous mixtures. NMR and IR results show a clear non-linear behaviour in molecular arrangement. This justifies the deviation of methanol and acetonitrile aqueous solution from the norm. However, both solvents showed similar ionization suppression effects on examples of weak acids and bases.. ...

Glycosylations range among the most common posttranslational modifications with an estimated 50% of all proteins supposed to be glycosylated. These modifications are required for essential cellular processes including cell-cell recognition, protein structure and activity, e.g., of surface receptors, as well as subcellular localization of proteins. Beside the elucidation of the carbohydrate structures, the annotation of glycosylation sites is of primary interest as a basis for subsequent functional characterization. Although mass spectrometry is the method of choice for large-scale analysis of glycosylation sites, it requires initial enrichment of glycopeptides prior mass spectrometric detection in most cases. In this paper, we present a novel approach for glycopeptide enrichment by electrostatic repulsion hydrophilic interaction chromatography (ERLIC). Glycopeptides were separated from the bulk of non-modified peptides and gradually eluted from the stationary phase with potential for isoform resolution.

Whole blood from the subjects will be drawn 30 minutes, 1 hour, 2 hours, 3 hours and 4 hours post clopidogrel dose. Once the blood is drawn, the metabolite will be derivatized to keep the metabolite stable in blood. Derivatization of the metabolite, involves spiking blood samples with 2-bromo-3methoxyacetophenone contained in an acetonitrile solution. Once derivatization has been done, metabolite levels will be analyzed using liquid chromatography mass spectrometry (LCMS). Once concentration levels of the active metabolite are known, the area under the curve will be calculated under trapezoid rule (linear up, log down ...
Three new compounds, (GuaH)4[W10O32](H2O)4 (1), (ThbH)3(H3O)[(W10O32](H2O)7.5 (2) and (ThbH)2[W6O19](H2O)2 (3) (GuaH = guaninium, thbH = theobrominium) were synthesized in acidified acetonitrile solutions. The polyoxotungstates in all of these compounds are surrounded by an organic matrix consisting of protonated purine bases and water molecules. The distinctive structural arrangement of the aromatic organic cations around the polyoxoanions parallel to their faces is reminiscent of nanosized boxes. The results of IR spectroscopy are consistent with previously reported results for polyoxotungstates and neat organic compounds. The polyoxoanions are reduced to tungsten(IV) oxide upon heating over 400 °C in an intramolecular redox reaction.

A normal-phase Bondapak high performance liquid chromatographic (HPLC) system was compared to two different reversed-phase Bondapak C//1//8 systems for separating and quantifying aldehydes and ketones. In the normal-phase system, isocratic elution with 2-propanol (IPA) and hexane produced the best results. One reversed-phase system consisted of two C//1//8 columns in series. The other reversed-phase system consisted of a single radial compression cartridge (RCC). Both reversed-phase systems employed solvent programming with acetonitrile/water as the mobile phase. Ultraviolet (UV) detection at 340 nm was used in all of the systems.

Biomanufacturers face a conflict between low-cost generic host cell protein (HCP) assays and highly sensitive but more costly process-specific HCP assays that are usually not initiated until the proof-of-concept stage. But drug developers cannot expect sufficient sensitivity from most commercially available generic assays. For some companies, multiproduct HCP assays could offer a solution to the dilemma. Biopharmaceutical manufacture using genetically modified microorganisms and cell lines is typically associated with contamination by process-related impurities. One of the most important…. ...
This chapter familiarizes readers with tempering and refrigeration treatments and their effect on case-carburized parts. It explains how tempering makes such parts easier to machine, more structurally and dimensionally stable, and more durable in certain applications. It identifies key process parameters and provides test data showing how they affect hardness, yield strength, bending and contact fatigue, and fracture toughness. It also addresses potential problems stemming from process-related factors such as the presence of hydrogen and the effects of aging and grinding. In regard to refrigeration, the chapter explains that it is not uncommon for subzero treatments to be included in the production of carburized parts whether as a standard procedure or optional step. Subzero cooling promotes the transformation of retained austenite to martensite, thereby increasing surface hardness and reducing the propensity of quenched carburized steels to burn and crack during surface grinding. The chapter ...
