A liquid chromatographic chiral stationary phase, which contains two N-CH3 amide connecting groups, based on (+)-(18-crown-6)-2,3,11,12-tetracarboxylic acid was first applied to the resolution of methoxyphenamine (2-methoxy-Nmethylamphetamine, a beta-adrenergic receptor agonist used as a bronchodilator). The resolution of methoxyphenamine on the chiral stationary phase containing two NCH3 amide connecting groups was quite successful with the separation factor (alpha) of 1.42 and resolution (RS) of 4.22 compared with those (a of 1.09 and RS of 1.55) on the chiral stationary phase containing two N-H amide connecting groups. In addition, the chiral stationary phase containing two N-CH3 amide connecting groups was applied to the resolution of methoxyphenamine analogues. From the comparison of the resolution results of methoxyphenamine with those of methoxyphenamine analogues on the chiral stationary phase containing two N-CH3 amide connecting groups, the Nmethyl group and the 2-methoxyphenyl group of methoxyphenamine were elucidated to be the structurally essential parts for the resolution on the chiral stationary phase.

3184-13-2, Name is H-Orn-OH Hydrochloride, molecular formula is C5H13ClN2O2, belongs to amides-buliding-blocks compound, is a common compound. In a patnet, author is Marinov, Marin, once mentioned the new application about 3184-13-2, Safety of H-Orn-OH Hydrochloride.

In the present study, cuttlefish skin gelatin (CSG) and protein isolate (CSPI) blend films were prepared and their physicochemical and antioxidant properties were characterized. CSG (4%, w/v) was blended with CSPI (3%, w/v) at different ratios in the presence of 15% of glycerol (w/w, plasticizer/polymer dry matter). Results showed that increasing CSPI content induced lower lightness but higher redness, yellowness and color difference values compared to CSG film. In addition, CSPI film had the lowest tensile strength (TS) and elongation at break (EAB) values. The FOR spectra of blend films showed a shift in the position of peaks related to the amide-I group, suggesting that they were involved in the interaction between the biopolymers. The structural properties evaluated by DSC showed a total miscibility between both polymers. This result was also confirmed by the SEM study, revealing a compact and homogenous structure in the blend films. Moreover, the water contact angle decreased in blend films, especially for those having higher proportion of CSPI. On the other side, the antioxidant activity of films was markedly enhanced by the CSPI incorporation. Therefore, CSPI addition into the gelatin matrix allowed to improve the blend films properties, mainly governed by the CSG/CSPI ratio. (C) 2017 Elsevier B.V. All rights reserved.

Orientation analysis of the beta-sheet structure within films of the established recombinant spider silk protein eADF4(C16) was performed using a concept based on dichroic transmission- and attenuated total reflection-Fourier transform infrared spectroscopy, lineshape analysis, assignment of amide I components to specific vibration modes, and transition dipole moment directions of beta-sheet structures. Based on the experimental dichroic ratio R, the order parameter S of beta-sheet structures was calculated with respect to uniaxial orientation. Films of eADF4(C16) were deposited on untexturized (Si) and unidirectionally scratched silicon substrates (Si-sc) and post-treated with MeOH vapor. Freshly cast thin and thick eADF4(C16) films out of hexafluoroisopropanol featured beta-sheet contents of approximate to 6%, which increased to >30% after MeOH post-treatment in dependence of time. Pseudo-first order folding kinetics were obtained, suggesting a transition from an unfolded to a folded state. In MeOH post-treated thin films with diameters in the nanometer range, a significant orientation of beta-sheets was obtained regardless of the texturization of the silicon substrate (Si, Si-sc). This was rationalized by dichroic ratios of the amide I component at 1696 cm(-1) assigned to the (0, pi) mode of antiparallel beta-sheet structures, whose transition dipole moment M is located in parallel to both beta-sheet plane and chain direction. The calculated high molecular order parameter S approximate to 0.40 suggested vertically (out-of-plane) oriented antiparallel beta-sheet stacks with tilt angles of gamma approximate to 39 degrees to the surface normal. Microscale (thick) films, in contrast, revealed low order parameters S approximate to 0. Scanning force microscopy on thin eADF4 films at silicon substrates showed dewetted polymer film structures rather at the micro-scale. These findings give new insights in the role of the beta-sheet crystallite orientation for the mechanical properties of spider silk materials.

Depression is a common mental disorder and is the leading cause of suicide globally. Because of the significant diversity in mental disorders, accurate diagnosis is difficult. Hence, the investigation of novel biomarkers is a key research perspective in psychotherapy to enable an individually tailored treatment approach. The prefrontal cortex (PFC) is a vital cortical region whose circuitry has been implicated in the development of depressive disorder. The endocannabinoid system (ECS) has garnered increasing attention because of its involvement in several diverse physiological brain processes including regulation of emotional, motivational and cognitive functions. The current review article explores the function of the key elements of the ECS as a biomarker in depressive disorder. The activity of endocannabinoids is thought to be moderated by the CB1 receptors in the central nervous system (CNS). Variations in the concentration of endocannabinoids and the binding affinity of CB1 receptors and their density have been identified in the PFC of persons with depression. Such discoveries support our theory that alteration in endocannabinoid function leads to the pathophysiological features of depressive disorders. Moreover, evidence from animal and human studies has revealed that dysfunction in endocannabinoid signalling can produce depression-like behaviours; therefore, improvement of endocannabinoid signalling may represent a new therapeutic approach for the management of depressive disorders.

Binary electrolytes of Li salt in ionic liquid (IL) are interesting systems for battery application. Typical for these systems is a strong Li-anion coordination causing vehicular Li+ transport in negatively charged Li-anion clusters and negative Li+ transference numbers. We investigate the influence of the additives tetrahydrofuran, monoglyme and triglyme on the Li+ migration behavior in 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide (EMImTFSA) based mixtures via electrophoretic NMR. When adding coordinating additives, we partly observe a reversal of the lithium migration direction and an electrophoretic drift of the neutral molecule. Using the same O:Li ratio, this effect is strongly depending on the chelating ability of the respective additive. Strongly coordinating additives form a chelate with the Li ion and render its drift velocity and its transference number positive, while the nonchelating additive tetrahydrofuran has a weaker effect on the Li drift. By choice of a suitable additive, it is therefore possible to decompose negatively charged lithium-anion clusters while maintaining ionic liquid-like properties. These findings provide a mechanistic explanation for the beneficial effect of additives on Li+ transport in IL-based battery cells.

The unique electronic reactivity of imidates has been recently exploited for the syntheses of diverse classes of N-heterocycles via C-N annulation reactions under acid/base/metal-catalyzed/radical-mediated reaction conditions. As opposed to amides, the imidate functionality provides both electrophilic and nucleophilic centers and eventually enhances its versatility as an organic synthon. In general, imidate motifs act as the soft nucleophiles that coordinate with transition metals to form stable 5-membered metallacycles to activate the proximal C-H bonds followed by annulation reactions to afford the desired N-heterocycles. The imidate precursor also generates in situ nitrogen radicals under suitable conditions to form C-N bonds via 1,5-HAT. This review highlights the recent application of imidates as building blocks for the synthesis of saturated and un-saturated N-heterocycles like oxazolines, oxazines, quinazolines, isoquinolines, imidazoles, and triazoles among others. Different reaction conditions, coupling partners, and imidate substrates reported in the literature have been addressed herein for the nitrogen-containing mono-, bi- and tricyclic ring systems.

We identified and characterized a series of pyrazole amides as potent, selective Ca(v)3.1-blockers. This series culminated with the identification of pyrazole amides 5a and 12d, with excellent potencies and/or selectivities toward the Ca(v)3.2-and Ca(v)3.3-channels. This compound displays poor DMPK properties, making its use difficult for in vivo applications. Nevertheless, this compound as well as analogous ones are well-suited for in vitro studies.
