Identification and photostability of N-alkylamides from Acmella oleracea extract

The identification of N-alkylamides from commercial Acmella oleracea extract, their UV-B photostability in different solvents, and identification of degradation products were the main goals of this study. By UHPLC-DAD-ESI-MS/MS method the presence of nine N-alkylamides was identified. Investigation of UV-B irradiation effect on identified N-alkylamides from Acmella oleracea extract was monitored in various the most commonly used solvents (methanol, ethanol, saline solution, and water) during 120 min. The results obtained indicated that spilanthol and homospilanthol were the most stable N-alkylamides presented in Acmella oleracea extract, while the photostability of identified N-alkylamides in whole in tested extract solutions decreased as follows: methanol>ethanol>saline solution>water. As the main degradation products in all investigated solutions 6,9-dihydroxy-deca-2,7-dienoic acid isobutyl-amide and 8,9-dihydroxy-deca-2,6-dienoic acid isobutyl-amide were identified.

Stereoselective Sulfinyl Aniline-Promoted Pd-Catalyzed C-H Arylation and Acetoxylation of Aliphatic Amides

Stereoselective functionalization of aliphatic C-H bonds presents a great challenge. Following this target, we disclose herein an original strategy towards direct arylation of aliphatic chains at ss-methylene position based on a use of amide-sulfoxide bicoordinating directing group. Although moderate to high chiral induction (up to 9:1d.r.) is achieved, diastereomerically pure compounds may be afforded by simple separation of diastereomeric products by silica gel chromatography. Accordingly, this reaction allows preparation of a large scope of high-value scaffolds in synthetically useful yields while recyclable character of our chiral auxiliary brings an additional benefit. A potential of this methodology to build up original molecules by sequential diarylation and expedient (two step) synthesis of a biologically active compound are further disclosed. Finally a first example of stereoselective direct acetoxylation of aliphatic chains is reported.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 5680-79-5 help many people in the next few years. COA of Formula: C3H8ClNO2.

Discovery of a potent orally bioavailable retinoic acid receptor-related orphan receptor-gamma-t (ROR gamma t) inhibitor, S18-000003

The retinoic acid receptor-related orphan receptor-gamma-t (ROR gamma t) is the master transcription factor responsible for regulating the development and function of T-helper 17 (Th17) cells, which are related to the pathology of several autoimmune disorders. Therefore, ROR(gamma)t is an attractive drug target for such Th17-mediated autoimmune diseases. A structure-activity relationship (SAR) study of lead compound 1 yielded a novel series of ROR(gamma)t inhibitors, represented by compound 6. Detailed SAR optimization, informed by X-ray cocrystal structure analysis, led to the discovery of a potent orally bioavailable ROR(gamma)t inhibitor 25, which inhibited IL-17 production in the skin of IL-23-treated mice by oral administration.

Dendrimer-functionalized electrospun nanofibres as dual-action water treatment membranes

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.

Aza-heterocyclic frameworks through intramolecular pi-system trapping of spiro-N-acyliminiums generated from isoindolinone

Spiro-acetoxylactams as key substrates were obtained straightforwardly by the tandem regioselective reduction/O-acylation of spiro-isoindolinone-imides. The latter were produced in large scale in three steps from homophthalic acid. These imides were useful to provide in one step isoindolinones bearing hydroxymethyl-amide functions, tethered at quaternary carbon centre with promising biological issues. Submitted to Bronsted (TFA neat) and Lewis acid (trimethylsilyltrifluoro-methanesulfonic (TMSOTf) 10 mol%), the spiro-acetoxylactams undergo pi-cyclization of spiro-N-acyliminiums to provide diastereoselectively with pi-aromatic original pyrrolopyrido- and pyrroloazepino-isoindoles fused or not to aromatic systems. With pi-olefins, pyrrolopyridines and pyrrolo-azepines fused to isoindoline or containing amino-acids were isolated. A reaction mechanism producing all these systems is also discussed.

Lower amygdala fatty acid amide hydrolase in violent offenders with antisocial personality disorder: an [C-11]CURB positron emission tomography study

Antisocial personality disorder (ASPD) imposes a high societal burden given the repetitive reactive aggression that affected individuals perpetrate. Since the brain endocannabinoid system (ECS) has been implicated in ASPD and aggressive behavior, we utilized [C-11]CURB positron emission tomography to investigate fatty acid amide hydrolase (FAAH), an enzyme of the ECS that degrades anandamide, in 16 individuals with ASPD and 16 control participants. We hypothesized that FAAH density would be lower in the amygdala for several reasons. First, decreased FAAH expression is associated with increased cannabinoid receptor 1 stimulation, which may be responsible for amygdala hyper-reactivity in reactive aggression. Second, the amygdala is the seat of the neural circuit mediating reactive aggression. Third, other PET studies of externalizing populations show reduced brain FAAH density. Conversely, we hypothesized that FAAH expression would be greater in the orbitofrontal cortex. Consistent with our hypothesis, we found that amygdala FAAH density was lower in the amygdala of ASPD (p=0.013). Cerebellar and striatal FAAH expression were inversely related with impulsivity (cerebellum: r=-0.60, p=0.017; dorsal caudate: r=-0.58, p=0.023; dorsal putamen: r=-0.55, p=0.034), while cerebellar FAAH density was also negatively associated with assaultive aggression (r=-0.54, p=0.035). ASPD presents high levels of disruptive behavior with few, if any, efficacious treatment options. Novel therapeutics that increase FAAH brain levels in a region-specific manner could hold promise for attenuating certain symptom clusters of ASPD, although our results require replication.

Peptide Couplings by Reactive Extrusion: Solid-Tolerant and Free from Carcinogenic, Mutagenic and Reprotoxic Chemicals

Industrial peptide synthesis is generally carried out in batches and suffers both from the production of tremendous amounts of toxic waste and the difficulty to handle solids. In this study, peptide couplings were performed at the multigram scale by using reactive extrusion in a CMR-free (CMR = Carcinogenic, Mutagenic or Reprotoxic), solid tolerant, fast, efficient and epimerization-free manner, opening the way for intensified and continuous industrial production of peptides.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 615-05-4. Quality Control of 4-Methoxybenzene-1,3-diamine.

Solvation of Amides in DMSO and CDCl3: An Attempt at Quantitative DFT-Based Interpretation of H-1 and C-13 NMR Chemical Shifts

The study concerns N-methyl-2-pyrrolidinone, N,N-dimethylformamide, 2-pyrrolidinone, N-methylformamide, and formamide in DMSO-d(6) and CDCl3 solutions. It has been shown that the results of DFT calculations [B3LYP and/or PBEO 6-311++G(2d,p), PCM] of molecular geometries and magnetic shielding are able to reproduce very well the amide H-1 NMR and C-13 NMR chemical shifts measured in these solvents provided that the specific solvation of the solute molecules and their association are taken into account and also that comparison of the experimental and theoretical data is carefully done. Analysis of the chemical shift data points out that in CDCl3 solutions primary and secondary amides are partially associated and that their carbonyl oxygen lone electron pairs are specifically solvated by solvent molecules. At the same time, association of the amides seems to be of minor importance in DMSO, while their N-H hydrogens form strong hydrogen bonds with solvent molecules.

Collision-induced dissociation of protonated fentanyl: A DFT study

The fragmentation pathways leading to the major products resulting from collision-induced dissociation of protonated fentanyl are investigated. Starting from a protonated fentanyl in a twist conformation, transfer of the proton from the piperidine to the amide nitrogen allows the lone pair of the piperidine nitrogen to assist in displacement of the amide group and results in ring-opening of the piperidine to yield an ion with m/z 188 (C13H18N+). This is the fragmentation pathway with the lowest energy barrier; the barrier to the loss of the phenethyl group as a phenonium or 1-phenylethyl cation from the nitrogen in the piperidine ring is 64 kJ mol(-1) higher in energy. At even higher collision energies a bicyclic ion, also with nominal m/z 188 but with different elemental composition (C12H14NO+), is formed after sequential losses of ethene and phenethylamine from protonated fentanyl. Possible pathways to ring opening of the piperidine ring of N-protonated fentanyl include nucleophilic attack by the amide oxygen or the phenyl ring on the piperidine ring. The two m/z 188 ions give different dissociation products; minor products in the mass spectrum of protonated fentanyl at m/z 146, 134 and 132 are all generated from the dominant m/z 188 ion, C13H18N+, whereas only a product at m/z 132 is formed from the C12H14NO+ ion.
