Polyaniline which is termed as PANi is chosen as model molecule where substitution with Li, Na, K, Be, Mg and Ca is carried out. Each metal is supposed to interact with PANi throughout the amide group at the terminal and then in the middle of PANi. Quantum mechanical calculations at B3LYP/6-31G (d,p) level are conducted for PANi as well as substituted PANi. Bond distances, bond angles, total dipole moment (TDM), frontier band gap energy (HOMO/LUMO) as well as molecular electrostatic potential (ESP) are calculated. Results indicate that for terminal amide group interaction, PANi-Na has the highest TDM (10.5996 Debye) and the lowest HOMO/LUMO band gap energy (2.0169 eV). Also for PANi-Ca, TDM (6.4356 Debye); HOMO/LUMO (1.1970 eV). For the interaction through the middle NH group, PANi-K and PANi-Mg are the more active sites for interaction as they have the highest TDM, having the the lowest HOMO/LUMO band gap energies of 1.6732 and 1.3168 eV values of 11.5939 and 3.1208 Debye respectively, and respectively. ESP drives a general conclusion that the electronegativity of PANi increases significantly by the presence of alkali metals and increases slightly by the presence of alkaline earth metals. Additionally, there are changes in the geometrical parameters (including both bond lengths and bond angles) for all studied model molecules.

Chronic psychological stress is an important public health issue which generates behavioral changes, anxiety, immunosuppression and oxidative damage. Piracetam is a cognitive enhancer, at cellular level it protects from oxidative stress. The aim of this study was to evaluate the effect of psychological stress and of piracetam on circulating mononuclear cells by analyzing the biochemical spectrome using Synchrotron Radiation Fourier Transform Infrared Microspectroscopy (SR-mu FTIR). Rats were exposed for five days to a stressor (cat odor) under oral administration of piracetam (600 mg/kg). SR-mu FTIR analysis showed a decrease in bands associated to the lipids region (2852 cm(-1), 2923 cm(-1) and 2962 cm(-1)) and an increase absorption of the amide I band (1654 cm(-1)) under stress conditions. The principal component analysis showed increase oxidation of lipids (decrease of 3010 cm(-1), 2923 cm(-1) and 2852 cm(-1) bands) as well as proteins denaturation (increase of 1610 cm-1 and 1690 cm(-1) bands) under stress. Piracetam provided protection to polyunsaturated lipids (p <= 0.001) and lipids/proteins ratio (p <= 0.001). Behaviorally, this drug diminished fear and anxiety in stressed animals by the plus maze test (p <= 0.002). However, this drug induced oxidative stress in mononuclear cells from unstressed animals and altered their behavior. (C) 2018 Elsevier B.V. All rights reserved.

The Friedel Crafts-type reaction between properly functionalized inden-1-ones and 2-naphthols generates a hindered single bond which displays a unique preference for an antiperiplanar conformational diastereoisomer. The steric hindrance and the presence of an enantioenriched stereogenic center control the distribution of the two diastereomeric conformers at equilibrium and increase the energy for the rotation of the C(sp(3))-C(sp(2)) single bond.

Asymmetric 1,4-addition reactions with nitroalkenes are valuable because the resulting chiral nitro compounds can be converted into various useful species often used as chiral building blocks in drug and natural product synthesis. In the present work, asymmetric 1,4-addition reactions of arylboronic acids with nitroalkenes catalyzed by a rhodium complex with a chiral diene bearing a tertiary butyl amide moiety were developed. Just 0.1 mol% of the chiral rhodium complex could catalyze the reactions and give the desired products in high yields with excellent enantioselectivities. The homogeneous catalyst thus developed could be converted to a reusable heterogeneous metal nanoparticle system using the same chiral ligand as a modifier, which was immobilized using a polystyrene-derived polymer with cross-linking moieties, maintaining the same level of enantioselectivity. To our knowledge, this is the first example of asymmetric 1,4-addition reactions of arylboronic acids with nitroalkenes in a heterogeneous system. Wide substrate generality and high catalytic turnover were achieved in the presence of sufficient water without any additives such as KOH or KHF2 in both homogeneous and heterogeneous systems. Various insights relating to a rate-limiting step in the catalytic cycle, the importance of water, role of the secondary amide moiety in the ligand, and active species in the heterogeneous system were obtained through mechanistic studies.

Soluble epoxide hydrolase (sEH) is an alpha/beta hydrolase fold protein and widely distributed in numerous organs including the liver, kidney, and brain. The inhibition of sEH can effectively maintain endogenous epoxyeicosatrienoic acids (EETs) levels and reduce dihydroxyeicosatrienoic acids (DHETs) levels, resulting in therapeutic potentials for cardiovascular, central nervous system, and metabolic diseases. Therefore, since the beginning of this century, the development of sEH inhibitors is a hot research topic. A variety of potent sEH inhibitors have been developed by chemical synthesis or isolated from natural sources. In this review, we mainly summarized the interconnected aspects of sEH with cardiovascular, central nervous system, and metabolic diseases and then focus on representative inhibitors, which would provide some useful guidance for the future development of potential sEH inhibitors.

The aminohydroxylation of various alkenes using FmocNHCl as a nitrogen source is reported. In general, in the absence of a ligand, the reaction provided racemic Fmoc-protected amino alcohols with excellent regioselectivity but in low to moderate yields. However, in some instances, the yield of an amino alcohol product and the regioselectivity could be altered by the addition of a catalytic amount of triethylamine (TEA). The Sharpless asymmetric variant of this reaction (Sharpless asymmetric aminohydroxylation (SAAH)), using (DHQD)(2)PHAL (DHQD) or (DHQ)(2)PHAL (DHQ) as chiral ligands, proceeded more readily and in higher yield compared to the same reaction in the absence of a chiral ligand. The enantiomeric ratios (er) of all but two examples exceeded 90:10 with many examples giving er values of 95:5 or higher, making FmocNHCl a highly practical reagent for preparing chiral amino alcohols. The SAAH reaction using FmocNHCl was used for the preparation of D-threo-beta-hydroxyasparagine and D-threo-beta-methoxyaspartate, suitably protected for Fmoc solid phase peptide synthesis.

This work reports the preparation of composite electrospun membranes combining antimicrobial action with the capacity of retaining low-molecular weight non-polar pollutants. The membranes were electrospun blends of polyvinyl alcohol (PVA) and poly(acrylic acid) (PAA) stabilized using heat curing. The membranes were functionalized by grafting amino-terminated poly(amidoamine) (PAMAM) G3 dendrimers. The antimicrobial effect was assessed using strains of Escherichia coli and Staphylococcus aureus by tracking their capacity to form new colonies and their metabolic impairment upon contact with membranes. The antimicrobial activity was particularly high to the gram-positive bacterium S. aureus with a 3-log reduction in their capacity to colonize dendrimer-functionalized membranes with respect to neat PVA/PAA fibers. The effect to gram-positive bacteria was attributed to the interaction of dendrimers with the negatively charged bacterial membranes and resulted in membranes essentially free of bacterial colonization after 20 h in contact with cultures at 36 degrees C. The adsorption of toluene on PAA/PVA fibers and on dendrimer-functionalized membranes was assayed using toluene over a broad concentration range. The host-guest encapsulation of toluene inside dendrimer molecules was computed through docking studies, which allowed calculating a maximum capacity of 14 molecules of toluene per molecule of PAMAM G3. The theoretical prediction was in good agreement with the experimental capacity at the higher concentrations assayed. (C) 2017 Elsevier B.V. All rights reserved.

The Ni-catalyzed reaction of ortho-phenoxy-substituted aromatic amides with alkynes in the presence of (LiOBu)-Bu-t as a base results in C-O/N-H annulation with the formation of 1(2H)-isoquinolinones. The use of a base is essential for the reaction to proceed. The reaction proceeds, even in the absence of a ligand, and under mild reaction conditions (40 degrees C). An electron-donating group on the aromatic ring facilitates the reaction. The reaction was also applicable to carbamate (C-O bond activation), methylthio (C-S bond activation), and cyano (C-CN bond activation) groups as leaving groups.

The transamidation reactions of unprotected mono- and disaccharidic carboxamides with various primary and secondary arylic, heterocyclic or aliphatic amines are described. This new method is green and atom efficient and gives good to high yields. Notably, the conditions do not require either a solvent or a catalyst and give ammonia as a single by-product. The described coupling reaction is compatible with a variety of functional groups and was used in the synthesis of various glycosidic derivatives and biologically relevant glycolipids. A plausible reaction mechanism involving an intermolecular H-bond activation of the starting carboxamides is proposed.
