BACKGROUNDAquatic source gelatins are gaining more attention due to the advantages in safety and religion acceptability compared with mammalian sources. For understanding the effects of extracting temperature on gelatins from chum salmon (Oncorhynchus keta) skins (GCSS), gelatins were extracted at temperatures from 40 to 90 degrees C and the physiochemical properties of GCSS were investigated. RESULTSGCSS yield increased while imino acids content declined as the increase of temperature. GCSS40, 50 and 60 showed strong -, 1- and 2-chains but the three faded in GCSS70, 80 and 90, with the presence of low molecular weight fragments. Amides A, I and III were shifted to higher wavenumber in GCSS70, 80 and 90 compared with that of GCSS40, 50 and 60. X-ray diffraction showed lower intensity of peak at 7 degrees in GCSS80 and 90 than in the other GCSS. Gel strength declined while a*, b* and E* value increased as temperature increased. Foam expansion and stability of GCSS40, 50 and 60 were lower than those of GCSS70, 80 and 90. Emulsion activity and stability decreased as temperature increased. CONCLUSIONExtracting temperature greatly affected yield, molecular composition and functionalities of GCSS. A temperature lower than 50 degrees C is recommended for GCSS extraction.

A series of molybdenum pincer complexes has been shown for the first time to be active in the catalytic hydrogenation of amides. Among the tested catalysts, Mo-1a proved to be particularly well suited for the selective C-N hydrogenolysis of N-methylated formanilides. Notably, high chemoselectivity was observed in the presence of certain reducible groups including even other amides. The general catalytic performance as well as selectivity issues could be rationalized taking an anionic Mo(0) as the active species. The interplay between the amide CO reduction and the catalyst poisoning by primary amides accounts for the selective hydrogenation of N-methylated formanilides. The catalyst resting state was found to be a Mo-alkoxo complex formed by reaction with the alcohol product. This species plays two opposed roles – it facilitates the protolytic cleavage of the C-N bond but it encumbers the activation of hydrogen.

The synthesis of four novel, tridentate aminophenolate ligands HL1-HL4, bearing amide functionalities is reported. Reaction of these ligands with a dioxido molybdenum(VI) precursor led, depending on the choice of solvent, to mononuclear complexes of the type [MoO2L(OMe)] (2, 4, 6) or dinuclear complexes [{MoO2L}(2)(mu-O)] (1, 3, 5, 7), containing one facially, tridentate ONO-ligand per metal center. This synthetic discrimination between dinuclear and mononuclear complexes allows for a comparison between structures and reactivity. Complexes 1-7 were found to be highly active catalysts in the epoxidation of several internal and terminal alkenes. With tent-butyl hydroperoxide (TBHP) as oxidant, precatalyst loadings of 0.0005 mol% (5 ppm) could be realized leading to turnover numbers of up to 110000. The pre-catalysts also allowed for the use of hydrogen peroxide (0.1 mol% precatalyst) as oxidant as well as various alcohols as green solvents, such as ethanol or even tert-butanol (usually an inhibitor of epoxidation).

The endocannabinoid (eCB) system plays a significant role in the pathophysiology of depression. The potential participation of this system in the mechanism of action of antidepressants has been highlighted in recent years. The aim of this study was to investigate the expression of cannabinoid (CB) receptors using Western blot and CBI receptor density using autoradiography after acute or chronic administration of antidepressant drugs [imipramine (IMI, 15 mg/kg), escitalopram (ESC, 10 mg/kg) and tianeptine (TIA, 10 mg/kg)]. Antidepressants given chronically elevated CB1 receptor density in the cortical structures and hippocampal areas, while a decrease of CB1 receptor density was observed in the striatum after IMI and ESC treatment. The CB1 receptor expression decreases in the dorsal striatum after chronic administration of IMI and ESC or the receptor rise in the hippocampus after chronic ESC and TIA treatment were confirmed using Western blot analyses. An increase in the CB2 receptor expression was observed in the cortical structures and hippocampus after chronic administration of ESC and TIA, while a decrease in this expression was noted in the striatum and cerebellum after chronic IMI treatment. Our results provide clear evidence that the antidepressant exposures provoke some modulations within the eCB system through CB receptors. (C) 2017 Elsevier B.V. All rights reserved.

Purpose The value of relaxation-compensated amide proton transfer (APT) and relayed nuclear Overhauser effect (rNOE) chemical exchange saturation transfer (CEST)-MRI has already been demonstrated in various neuro-oncological clinical applications. Recently, we translated the approach from 7T to a clinically relevant magnetic field strength of 3T. However, the overall acquisition time was still too long for a broad application in the clinical setting. The aim of this study was to establish a shorter acquisition protocol whilst maintaining the contrast behavior and reproducibility. Methods Ten patients with glioblastoma were examined using the previous state-of-the-art acquisition protocol at 3T. The acquired spectral data were retrospectively reduced to find the minimal amount of required information that allows obtaining the same contrast behavior. To further reduce the acquisition time, also the image readout was accelerated and the pre-saturation parameters were further optimized. Results In total, the overall acquisition time could be reduced from 19 min to under 7 min. One key finding was that, when evaluated by the relaxation-compensated inverse metric, a contrast correction for B-1-field inhomogeneities at 3T can also be achieved reliably with CEST data at only one B-1 value. In contrast, a 1-point B-1-correction was not sufficient for the common linear difference evaluation. The reproducibility of the new clinical routine acquisition protocol was similar to the previous state-of-the-art protocol with limits of agreement below 20%. Conclusions The substantial reduction in acquisition time by about 64% now allows the application of 3D relaxation-compensated APT and rNOE CEST-MRI for examinations of the human brain at 3T in clinical routine.

Lithium-sulfur battery (LSB) is considered as a potential candidate for future energy storage device due to its high specific capacity and energy density as well as the natural abundance of sulfur. However, poor capacity retention, polysulfide shuttle effect, and low electronic conductivity have hindered practical uses of the LSB. The introduction of interlayer has been proven to be a promising strategy to improve the overall performance of the LSB. Herein, the influence of various amine-based functional groups of carbon interlayer on lithium polysulfide (LPS) chemisorption was compared via electrochemical methods and density functional theory (DFT) calculations. The functionalized carbon interlayers with 4-aminobenzoic acid, 1,6-diaminohexane, p-phenylenediamine, 4-nitroaniline, and 4-aminothiophenol prepared by an amide coupling reaction show a strong contribution to reduce the polysulfide migration, resulting in the enhancement of overall LSB performances such as a superior capacity and high Coulombic efficiency along with long cyclability of the cells. The LSB with 4-aminobenzoic acid could achieve an initial specific capacity of 1694 mAh g(-1) (0.1 C) with an extremely low capacity decay of 0.055% per cycle due to the cooperative interaction of H- and Li-bonds between 4-aminobenzoic acid-functionalized interlayer and polysulfides.

The macronutrient potassium (K) has vital physiological functions in plants and its availability can strongly impact quality of crops like tomato. The impact of K nutrition on conventional tomato fruit quality parameters has been described several times, but detailed investigations on the effect of K supply on the fruit metabolite profile are still rare. To fill this gap, we investigated the influence of K fertilization on the metabolite profile of tomato fruits. For this purpose, an outdoor pot experiment with three different cocktail tomato cultivars was performed. A fertilization regimen with five K levels was applied, ranging from deficiency to sufficient supply. Fruit samples were analyzed by untargeted GC x GC-MS to cover the primary metabolite profile as well as some secondary metabolites. As verified using ICP-OES, fruit K content was highly proportional to the supplied amount of K. At the metabolite profile level, the most prominent and cultivar-independent effect of increased K fertilization was the rise of tricarboxylic acid (TCA) cycle intermediates. Further effects were more cultivar-specific, for example an increase of the mobile nitrogen pool (e.g. amines like putrescine and amides like asparagine), changes in the profile of minor sugars (especially disaccharides) as well as higher levels of some secondary metabolites. Pronounced response patterns were mainly observed in the cultivars Primavera and Yellow Submarine that were recently characterized as higher yielding, demanding a stronger consideration of cultivar differences in future studies.

Chemoenzymatic Posttranslational Modification Reactions for the Synthesis of psi[CH2NH]-Containing Peptides

The psi[CH2NH] reduced amide bond is a peptide isostere widely used in the development of bioactive pseudopeptides. Reported here is a method of chemoenzymatic posttranslational modification for the synthesis of psi[CH2NH]-containing peptides converted from ribosomally expressed peptides. The posttranslational conversion composed of an enzymatic cyclodehydration and facile two-step chemical reduction achieves deoxygenation of a specific amide bond present in a nonprotected peptide in water. This method generates the psi[CH2NH] bond in peptides and is applicable to various peptide sequences, potentially enabling the preparation of a library of psi[CH2NH]-containing peptides.

The amino-terminal heptapeptide of the algesic substance P provides analgesic effect in relieving chronic neuropathic pain

Of painful conditions, somatic pain of acute nociceptive origin can be effectively managed clinically, while neuropathic pain of chronic neuropathy origin is difficult to control. For molecules involved in pain sensation, substance P (SP) is algesic, exacerbating painful sensation, while its amino-terminal fragment, heptapeptide SP(1-7), confers biological activities different from its full-length parent neuropeptide precursor. We previously demonstrated SP(1-7) interaction with pain processing to alleviate chronic pain. Here we evaluated SP(1-7) and its C-terminal amidated analogue SP(1-7) amide, together with SP and opioid agonist DAMGO. We tested mouse behaviors of both acute somatic pain in tail-flick latency assay, and neuropathic pain in sciatic nerve injury model of chronic constriction injury (CCI). DAMGO produced dose-dependent analgesia for somatic pain as expected, so did both SP(1-7) and its analogue SP(1-7) amide, while SP yielded the opposite effect of algesia, in a phenomenon we termed `contrintus’, meaning ‘opposite from within’ to denote that two peptides of the same origin (SP and its metabolic fragment SP(1-7)) produced opposite effects. In CCI model, DAMGO showed a general reduction in allodynia sensitivity for both nerve-injured and normal paws, without selective effect for neuropathic pain, consistent with clinical observation that opioids are less effective for chronic neuropathic pain. On the other hand, both SP(1-7) and SP(1-7) amide displayed dose-dependent anti-allodynia effect that is selective for neuropathic pain. These findings suggest that SP(1-7) and its analogue may be useful for developing pharmaceuticals to treat neuropathic pain.
