Using chiral amino amide ionic liquids as the ligands, a new chiral ligand exchange capillary electrophoresis method with Cu(II) as the central ion was constructed for enantioseparation of labeled D,L-amino acids. The effects of key parameters, including pH value of the running buffer, the ratio of Cu(II) to chiral amino amide ionic liquids, the concentration of complexes based on Cu(II)-chiral amino amide ionic liquids were investigated. It has been observed that eight pairs of labeled D,L-amino acids could be baseline-separated with a running buffer of 15.0 mM ammonium acetate, 10.0 mM Cu(II) and 20.0 mM L-phenylalaninamide based ionic liquid at pH 5.0. The quantitation of D,L-amino acids was conducted and good linearity (r(2) >= 0.964) was obtained. Furthermore, an assay for determining the enantiomeric purity of D,L-amino acids was developed and the possible enantiorecognition mechanism was discussed briefly. The results indicated that the chiral amino amide ionic liquids could play the role of ligands in chiral ligand exchange capillary electrophoresis system and exhibit great potential in chiral analysis.

The present study explored the protective effects of cannabinoid receptor agonist WIN55,212-2 (WIN) and fatty acid amide hydrolase inhibitor URB597 (URB) against neuroinflammation in rats with chronic cerebral hypoperfusion (CCH). Activated microglia, astrocytes, and nuclear factor kappa B (NF-kappa B) p65-positive cells were measured by immunofluorescence. Reactive oxygen species (ROS) was assessed by dihydroethidium staining. The protein levels of cluster of differentiation molecule 11b (OX-42), glial fibrillary acidic protein (GFAP), NF-kappa B p65, inhibitor of kappa B alpha (I kappa B-a), I kappa B kinase a/beta (IKK a/beta), phosphorylated IKK a/beta (p-IKK a/beta), cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), tumor necrosis factor (TNF)-alpha, and interleukin-1 beta (IL-1 beta) were examined by western blotting or enzyme-linked immunosorbent assay. All the protein levels of OX-42, GFAP, TNF-a, IL-1 beta, COX-2, and iNOS are increased in CCH rats. WIN and URB downregulated the levels of OX-42, GFAP, TNF-alpha, IL-1 beta, COX-2 and iNOS and inhibited CCH-induced ROS accumulation in CCH rats, indicating that WIN and URB might exert their neuroprotective effects by inhibiting the neuroinflammatory response. In addition, the NF-kappa B signaling pathway was activated by CCH in frontal cortex and hippocampus, while the aforementioned changes were reversed by WIN and URB treatment. These findings suggest that WIN and URB treatment ameliorated CCH-induced neuroinflammation through inhibition of the classical pathway of NF-kappa B activation, resulting in mitigation of chronic ischemic injury.

Surface adsorption of a dipeptide L-alanyl-L-tryptophan (Ala-Trp) on gold nanoparticles reduced by citrate (CT) and borohydride (BH) ions was investigated by a surface-enhanced Raman scattering (SERS) technique. Two distinct SERS spectra of Ala-Trp depending on the types of gold nanoparticles were observed, and the vibrational assignments were based on the density functional theory simulations and the previous SERS results of Trp. Ala-Trp mainly adsorbs through the amine group on CT gold nanoparticles with a perpendicular orientation of the indole ring to the surface. In contrast, the adsorption occurs via the pi electrons of the indole ring on the BH gold surfaces while maintaining a flat geometry of the indole ring to the surface. The amide I band of Ala-Trp was observed only with the CT gold colloids in acidic and neutral conditions where partial surface adsorption via the amide group is expected. (C) 2020 Elsevier B.V.

The C-N bond character is dependent directly upon the resonance-contributor structure population driven by the delocalized nitrogen lone-pair of electrons. In the case of N, N-dibenzyl-ortho-toluamide (o-DBET), the molecule adopts subpopulations of conformers with distinct NMR spectral features, particularly at low temperatures. This conformational adaptation is unique to o-DBET, while the corresponding meta- and para- forms do not show such behavior. Variable-temperature (VT) NMR, two-dimensional exchange spectroscopy (EXSY), and qualitative molecular modeling studies are used to demonstrate how multiple competing interactions such as restricted amide rotation and steric hindrance effects can lead to versatile molecular adaptations in the solution state.

Nylon 6 fibers are produced by polymerization of caprolactam obtained after oximation and Beckmann rearrangement of cyclohexanone. For this reason, the purity of cyclohexanone used is an important parameter to control the quality of final nylon 6 products. The poor quality of cyclohexanone is related to the presence of some cyclic ketone impurities, such as 2-methylcyclopentanone, n-methylcyclohexanones (n = 2, 3, and 4), and 2-cyclohexen-1-one, which can remain after the purification process of cyclohexanone. In this study, the first step was to study the products promoted during the oximation of these cyclic impurities. The oximation of each impurity was carried out at T = 80 degrees C and pH = 5, and the reaction products were identified using gas chromatography-mass spectrometry (GC/MS) and NMR Each cyclic oxime promoted a mixture of cis and trans stereoisomers, and the relative production ratio was determined. Additionally, the operating conditions that can affect the oximation step were studied. To do that, cyclohexanone was spiked with the mentioned cyclic impurities, and the oximation reaction was carried out using an aqueous solution of hydroxylammonium sulfate. The effects of experimental conditions, such as temperature (353.15-358.15 K) and pH (3.5-6), were studied. It was found that the higher the temperature, the higher the impurity conversion. However, when the pH was studied, the conversion of impurities presented a maximum due to the oximation mechanism. Additionally, a kinetic model of oximation reaction of cyclohexanone spiked with the cyclic impurities, based on an apparent constant to take into account that the reaction was carried out in two liquid phases, was proposed to explain the experimental results. The apparent kinetic constants obtained for 2-methylcyclohexanone and 2-cyclohexen-1-one were similar but lower than that for 2-methylcyclopentanone. The study was completed promoting the Beckmann rearrangement of the oxime mixtures obtained from the oximation of pure cyclic impurities under mild conditions (sulfuric media at 100 degrees C). The amides produced were identified by gas chromatograph/mass selective detector (GC/MSD). Cis/trans oxime stereoisomers from n-methylcyclohexanones (n = 2 and 3) and 2-methylcydopentanone presented the same reactivity to the corresponding amides, but only(Z)-2-cyclohexen-1-one oxime reacts in the Beckmann rearrangement to produce its cyclic amide.

In migraine pain, cannabis has a promising analgesic action, which, however, is associated with side psychotropic effects. To overcome these adverse effects of exogenous cannabinoids, we propose migraine pain relief via activation of the endogenous cannabinoid system (ECS) by inhibiting enzymes degrading endocannabinoids. To provide a functional platform for such purpose in the peripheral and central parts of the rat nociceptive system relevant to migraine, we measured by activity-based protein profiling (ABPP) the activity of the main endocannabinoid-hydrolases, monoacylglycerol lipase (MAGL) and fatty acid amide hydrolase (FAAH). We found that in trigeminal ganglia, the MAGL activity was nine-fold higher than that of FAAH. MAGL activity exceeded FAAH activity also in DRG, spinal cord and brainstem. However, activities of MAGL and FAAH were comparably high in the cerebellum and cerebral cortex implicated in migraine aura. MAGL and FAAH activities were identified and blocked by the selective and potent inhibitors JJKK-048/KML29 and JZP327A, respectively. The high MAGL activity in trigeminal ganglia implicated in the generation of nociceptive signals suggests this part of ECS as a priority target for blocking peripheral mechanisms of migraine pain. In the CNS, both MAGL and FAAH represent potential targets for attenuation of migraine-related enhanced cortical excitability and pain transmission.

A series of 7-O-amide hesperetin derivatives were subjected to multi-target biological evaluation of anti-Alzheimer’s disease. Most of the compounds showed good in vitro inhibitory activity against cholinesterase, of which compound 7c (7-O-(4-(morpholinoethyl)-acetamide) hesperetin) was the most effective anti-eqBuChE derivative (IC50 = 0.28 +/- 0.05 mu M) and exerted neuropmtective effects. Further biological evaluation found that compounds 4d, 4e and 7c showed strong antioxidant, anti-A beta self-aggregation and anti-neuroinflammatory activities. Compound 7c could inhibit the expression of iNOS and COX-2 proteins and prevent LPS-induced inflammatory response in BV2 cells. In addition, compound 7c could chelate biometal ions such as Cu2+ and Zn2+. In the vivo study, the MWM test confirmed that compound 7c could improve the cognitive impairment caused by scopolamine. In summary, the above studies have shown that the optimized compound 7c has great development potential as MTDL for the treatment of AD.

Thermo-responsive polymers undergo a reversible coil-to-globule transition in water after which the chains collapse and aggregate into bigger globules when passing to above its lower critical solution temperature (LCST). The hydrogen bonding with the amide groups in the side chains has to be contrasted with the hydration interaction of the hydrophobic main-chain hydrocarbons. In the present investigation we study molecular changes in the polymer poly(N-isopropyl acrylamide) (PNIPAM) and in its monomer N-isopropyl acrylamide (NIPAM) in solution across the LCST transition. Employing Fourier-transform infrared spectroscopy we probe changes in conformation and hydrogen bonding. We observe a nearly discontinuous shift of the peak frequencies and areas of vibrational bands across the LCST transition for PNIPAM whereas NIPAM exhibits a continuous linear change with temperature. This supports the crucial role of the polymer backbone with respect to hydration changes in the amide group in combination with cooperative interactions of bound water along the backbone chain.

The inherent bioinertness and potential bacterial infection risk are the two leading causes for Ti implant failure. To improve osseointegration and antibiosis, in this work, a novel antimicrobial osteogenic growth peptide was first synthesized by conjugating osteogenic growth peptide (OGP) and ciprofloxacin (CIP). Then, the synthetic antimicrobial peptide was immobilized onto Ti implant surface for chemoselective binding via the amide reaction. Thereafter, the capabilities of modified Ti implant on osseointegration and antibiosis were measured with cell experiments and antimicrobial activity in vitro. The results showed that antimicrobial osteogenic growth peptide (OGP-CIP) was successfully prepared and grafted onto Ti implant surface. Moreover, the antimicrobial peptide-modified Ti implants could promote osteoblasts spreading and osteodifferentiation compared with unmodified Ti substrates. Meanwhile, in vitro bacteria studies (Staphylococcus aureus and Escherichia coli) proved that the antibacterial property of antimicrobial peptide functionalized Ti implant was improved obviously. The method used in this work is a feasible and promising strategy to win the race against invading bacteria and accelerate bone integration in orthopedic implantation.
