Hydrogen deuterium exchange (HDX) coupled to mass spectrometry (MS) is a well-established technique employed in the field of structural MS to probe the solvent accessibility, dynamics and hydrogen bonding of backbone amides in proteins. By contrast, fast photochemical oxidation of proteins (FPOP) uses hydroxyl radicals, liberated from the photolysis of hydrogen peroxide, to covalently label solvent accessible amino acid side chains on the microsecond-millisecond timescale. Here, we use these two techniques to study the structural and dynamical differences between the protein beta(2)-microglobulin (beta(2)m) and its amyloidogenic truncation variant, Delta N6. We show that HDX and FPOP highlight structural/dynamical differences in regions of the proteins, localised to the region surrounding the N-terminal truncation. Further, we demonstrate that, with carefully optimised LC-MS conditions, FPOP data can probe solvent accessibility at the sub-amino acid level, and that these data can be interpreted meaningfully to gain more detailed understanding of the local environment and orientation of the side chains in protein structures.

Nitrites are the upstream precursors of the carcinogenic nitrosamines, which are widely found in the natural environment and many food products. It is important to develop a simple and sensitive sensor for detecting nitrites. In this work, a fluorescence probe based on nitrogen-doped carbon quantum dots (N-CQDs) was developed for the sensitive and selective determination of nitrites. At pH 2, the fluorescence of N-CQDs can be selectively quenched by nitrite due to the fact N-nitroso compounds can be formed in the reaction of amide groups with nitrous acid, which results in fluorescence static quenching. Under optimal conditions, fluorescence intensity quenching upon addition of nitrite gives a satisfactory linear relationship covering the linear range of 0.2-20 M, and the limit of detection (LOD) is 40 nM. Moreover, this method has been successfully applied to the determination of nitrites in tap water, which indicates its great potential for monitoring of nitrites in environmental samples.

BACKGROUND AND PURPOSE Gabapentin is commonly prescribed for nerve pain but may also cause dizziness, sedation and gait disturbances. Similarly, inhibition of the endogenous cannabinoid enzyme monoacylglycerol lipase (MAGL) has antinociceptive and anti-inflammatory properties but also induces sedation in mice at high doses. To limit these side effects, the present study investigated the analgesic effects of coadministering a MAGL inhibitor with gabapentin. EXPERIMENTAL APPROACH Mice subjected to the chronic constriction injury model of neuropathic pain were administered the MAGL inhibitor KML29 (1-40 mg.kg(-1), i.p.), gabapentin (1-50 mg.kg(-1), i.p.) or both compounds. Mice were tested for mechanical and cold allodynia. The function and expression of cannabinoid CB1 receptors in whole brain homogenates and lipid profile of spinal cords were assessed after repeated drug administration. KEY RESULTS The combination of low-dose KML29: gabapentin additively attenuated mechanical allodynia and synergistically reduced cold allodynia. The CB1 antagonist, rimonabant, partially reversed the anti-allodynic effects of KML29: gabapentin in mechanical allodynia but not cold allodynia. The anti-allodynic effects of KML29: gabapentin did not undergo tolerance inmechanical allodynia after repeated administration but produced mild tolerance in cold allodynia. High dose KML29 alone reduced CB1 receptor expression and function, but KML29: gabapentin reduced the density of CB1 receptors but did not alter their function. KML29: gabapentin influenced additional signalling pathways (including fatty acids) other than the pathways activated by a higher dose of either drug alone. CONCLUSION AND IMPLICATIONS These data support the strategy of combining MAGL inhibition with a commonly prescribed analgesic as a therapeutic approach for attenuating neuropathic pain.

A potentiometric sensor based on carbon paste electrode impregnated concurrently with molecularly imprinted polymer (MIP) and multi-walled carbon nanotubes (MWCNTs) was fabricated and used to measure stavudine (STV), currently applied as a drug in the treatment of human immuno-deficiency virus (HIV) infection. To synthesize the MIP, methacrylic acid (or acryl amide) and ethylene glycol dimethacrylate were utilized as functional monomer and cross-linker, respectively. The kind of the functional monomer had decisive influence on the response of the MIP-based electrode to target molecule of STV. MWCNTs had positive effect on both sensitivity and detection range of the electrode. The electrode response behavior (Nernstian behavior) was shown to be affected by homoconjugation of STV molecules in the imprinting process. The proposed sensor exhibited Nernstian slope of 27.9 mV per decade for stavudine over a wide concentration range of 1.0 x 10(-6) to 1.0 x 10(-1) mol L-1, with a detection limit of 5.0 x 10(-7) mol L-1. The sensor was used for STV determination in pharmaceutical samples.

The Rh-III-catalyzed allylic C-H alkynylation of non-activated terminal alkenes leads selectively to linear 1,4-enynes at room-temperature. The catalytic system tolerates a wide range of functional groups without competing functionalization at other positions. Similarly, the vinylic C-H alkynylation of alpha,beta- and beta,gamma- unsaturated amides gives conjugated Z-1,3-enynes and E-enediynes.

The development of a multifunctional nanoprobe capable of non-invasive multimodal imaging is crucial for precise tumour diagnosis. Herein, we report a facile polymer-assisted method to produce Au-Fe3O4 nanocomposites (NCPs) for the dual-modal magnetic resonance (MR) and X-ray computed tomography (CT) imaging of tumours. In this approach, amino-functionalized Au nanospheres were first obtained by surface modification of the bifunctional polymer SH-PEG-NH2. Hydrophilic and carboxyl-functionalized Fe3O4 nanoparticles were produced by phase transfer of reverse micelle oxidation in our previous work. The Au nanoparticles were conjugated with hydrophilic Fe3O4 nanoparticles through an amide reaction. The obtained Au-Fe3O4 nanocomposites display a high r(2) relativity (157.92 mM(-1) s(-1)) and a Hounsfield units (HU) value (270 HU) at Au concentration of 8 mg/mL and could be applied as nanoprobes for the dual-modal MR/CT imaging of a xenografted tumour model. Our work provides a facile method to prepare Au-Fe3O4 nanocomposites for dual-modal MR/CT imaging, and this method can be extended to prepare other multifunctional nanoparticles for multimodal bioimaging.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 34381-71-0, Name is (S)-(-)-1-Methyl-2-pyrrolidinemethanol, formurla is C6H13NO.

Reprocessable acrylate vitrimer needs to enhance its strength to expand the application in photo-three-dimensional (photo-3D) printing. However, the methods for improving mechanical properties by the addition of nanofillers or a multifunctional resin into acrylate vitrimers are inappropriate for photo-3D printing due to the low curing speed of photopolymerization induced by weakening light transmittance or reduction of dimensional accuracy caused by large shrinkage. At present, we demonstrate a new strategy for developing a kind of mechanically robust and reprocessable 3D printing thermosets by combining hydrogen bonds and exchangeable beta-hydroxyl esters into acrylate vitrimers. To realize this purpose, diacrylate prepolymer containing beta-hydroxyl esters was first synthesized from glycidyl methacrylate and suberic acid. Then, the resin formulations for 3D printing comprising the synthesized diacrylate prepolymer together with acrylamide generate exchanged beta-hydroxyl ester and pendent amide in cross-linked networks. Here, hydrogen bonds resulting from the amide group as sacrificial bonds dissipate vast mechanical energy under an external load. With the inclusion of 20 wt % acrylamide, the average tensile strength and Young’s modulus are up to 40.1 and 871 MPa, which increased by about 4.4 and 3.85 times, respectively. The network rearrangement of cross-linked vitrimers can be achieved through the dynamic ester exchange reactions with gradual disappearance of hydrogen bonds at elevated temperatures, imparting reprocessability into the printed structures. Various photo-3D printing or UV irradiation shapes were successfully produced, and these dissolved in ethylene glycol could be remolded again.

DECA, A Comprehensive, Automatic Post-processing Program for HDX-MS Data*

The open-source software, DECA, provides comprehensive back-end analysis of HDX-MS data that addresses the recent recommendations for HDX-MS data analysis and presentation. It provides options for back-exchange correction and rigorous statistical analysis of the significance of differences in exchange. Amide hydrogen-deuterium exchange mass spectrometry (HDX-MS) has become widely popular for mapping protein-ligand interfaces, for understanding protein-protein interactions, and for discovering dynamic allostery. Several platforms are now available which provide large data sets of amide hydrogen/deuterium exchange mass spectrometry (HDX-MS) data. Although many of these platforms provide some down-stream processing, a comprehensive software that provides the most commonly used down-stream processing tools such as automatic back-exchange correction options, analysis of overlapping peptides, calculations of relative deuterium uptake into regions of the protein after such corrections, rigorous statistical analysis of the significance of uptake differences, and generation of high quality figures for data presentation is not yet available. Here we describe the Deuterium Exchange Correction and Analysis (DECA) software package, which provides all these downstream processing options for data from the most popular mass spectrometry platforms. The major functions of the software are demonstrated on sample data.

Synthesis and Characterization of Carboxyl-terminated Polyethylene Glycol Functionalized Mesoporous Silica Nanoparticles

Colloidal mesoporous silica nanoparticles functionalized with carboxy-terminated polyethylene glycol (CMS-PEG-COOH) were successfully synthesized by covalently grafting dicarboxy-terminated polyethylene glycol (HOOC-PEG-COOH) on the surface of the amino functionalized CMS nanoparticles with amide bond as a cross linker. Moreover, the structural and particle properties of CMS-PEG-COOH were characterized by nuclear magnetic resonance spectroscopy (H-1-NMR), transmission electron microscopy (TEM), dynamic light scattering (DLS), nitrogen adsorption-desorption measurements, X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FT-IR). The nanomaterials presented a relatively uniform spherical shape morphology with diameters of about 120 nm, and favorable dispersibility in weak acid solution. The CMS-PEG-COOH exhibited no changes in the state of amorphous, while the mesopores sizes of 5.25 nm might provide the nanomaterials with large capacity for the loading and releasing of drugs. So the results indicated that CMS-PEG-COOH might be a critical nanomaterial for drug delivery system in the future.
