Scaffold hopping from the amide group of lead compound ONO 7300243 (1) to a secondary alcohol successfully gave a novel chemotype lysophosphatidic acid receptor 1 (LPA(1)) antagonist 4. Wash-out experiments using rat isolated urethra showed that compound 4 possesses a tight binding feature to the LPAI receptor. Further modification of two phenyl groups of 1 to pyrrole and an indane moiety afforded an optimized compound ONO-0300302 (19). Despite its high i.v. clearance, 19 inhibited significantly an LPA-induced increase of intraurethral pressure (IUP) in rat (3 mg/kg, p.o.) and dog (1 mg/kg, p.o.) over 12 h. Binding experiments with [H-3]-ONO-0300302 suggest that the observed long duration action is because of the slow tight binding character of 19.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 302-72-7, Name is DL-Alanine, SMILES is NC(C)C(O)=O, in an article , author is Gupta, Shyam Sunder R., once mentioned of 302-72-7, Name: DL-Alanine.

The first domino aza-Michael/intramolecular-Michael reaction employing acrylamides as key ambivalent partners for the synthesis of delta-lactams is presented. It has been shown that the desired reactivity is contingent to the presence of an N-alkoxy group within the acrylamides. Thus, in a base-catalyzed process that operates under mild conditions, N-alkoxyacrylamides are readily converted into polysubstituted delta-lactams in good yields with good to excellent stereocontrol.

alpha-glucosidase inhibitors (AGIs) are very attractive bioactive compounds due to their therapeutic profile that includes beneficial effects over glycemic control in type 2 diabetes mellitus and viral infections. Its detection and identification in plants and fruits has gained growing attention, and certainly requires efficient screening methodologies. The objective of the present work was to develop a fast methodology to detect and identify AGIs in cherimoya fruit (Annona cherimola Mill.) applying effect-directed analysis via high-performance thin layer-chromatography (HPTLC) linked with bioassay and mass spectrometry (MS). Both, HPTLC and bioassay conditions, were optimized accomplishing 50% and 83% reduction on enzyme concentration and incubation time respectively, compared to the original method. Additionally, the contrast between inhibitory bands and purple background was also enhanced by enzyme substrate impregnation on HPTLC plate. The optimized detection conditions established were the following: 5.0 U mL(-1) of enzyme solution, 1.0 mg mL(-1) of 2-naphthyl-alpha-D-glucopyranoside substrate, 1.0 mg mL(-1) of Fast Blue B salt solution and 10 min as incubation time. Applying this methodology, coupled to HPTLC-MS and ultra-high-performance liquid chromatography (UHPLC)-diode array detector (DAD)-MS/MS, it was possible for the first time to detect and identify three AGIs in cherimoya peel and seeds. Compounds were tentatively assigned as phenolamides (phenylethyl cinnamides): N-trans-feruloyl tyramine (m/z 314 [M+H](+) ; UV lambda(max) 293 and 316 nm), N-trans-p-coumaroyl tyramine (m/z 284 [M+H](+) ; UV lambda(max) 296nm) and N-trans-feruloyl phenethylamine (m/z 298 [M+H](+) ; UV lambda(max) 288 nm). To the best of our knowledge, the presence of latter compound is reported for the first time in cherimoya. (C) 2019 Elsevier B.V. All rights reserved.

Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, 600-21-5, Name is H-N-Me-DL-Ala-OH, SMILES is CC(NC)C(O)=O, in an article , author is Pringouri, Konstantina, once mentioned of 600-21-5, Application In Synthesis of H-N-Me-DL-Ala-OH.

Silver nanoparticles (AgNPs) were successfully synthesized through a simple green route using the Nelumbo nucifera leaf, stem and flower extracts. These nanoparticles showed characteristic UV-Vis absorption peaks between 410-450 nm which arises due to the plasmon resonance of silver nanoparticles. The Fourier transform infrared spectroscopy (FT-IR) confirmed the presence of amides and which acted as the stabilizing agent. X-ray diffraction spectrum of the nanoparticles confirmed the Face centered cubic (FCC) structure of the formed AgNPs. Dynamic light scattering technique was used to measure hydrodynamic diameter (68.6 nm to 88.1 nm) and zeta potential (-55.4 mV, -57.9 mV and 98.9 mV) of prepared AgNPs. The scanning electron micrographs of dislodged nanoparticles in aqueous solution showed the production of reasonably monodispersed silver nanoparticles (1-100 nm). The antimicrobial activity of prepared AgNPs was evaluated against fungi, Gram-positive and Gram-negative bacteria using disc diffusion method. Anti-corrosion studies were carried out using coupon method (mild steel and iron) and dye degradation studies were carried out by assessing photo-catalytic activity of Nelumbo nucifera extracts mediated AgNPs.

The fluorinated Nafion is replaceable by the non-fluorinated clean sulfonated poly (ether ether ketone) for hydrogen-based fuel cell. The acid-base blending of PAI to clean sulfonated poly ether ether ketone (SPEEK) increased the thermal, mechanical, and oxidative properties and decreased the conductivity. It interpreted that higher stability properties appeared on the blended membrane. The loading of BaCeO3 nanoparticles in the SPEEK/poly (amide-imide) (PAI) matrices was done via solution casting process. This outcome provides improved conductivity, ion-exchange property, water uptake (WU) with controlled stability due to the good interfacial interplay among nanoparticles and polymer. The high conductivity (14.98 x 10(-3) S cm(-1) at 80 degrees C) was reached by SPEEK/PAI /BaCeO3 (90/10/06 wt%) membrane (B3) measured in the electrochemical four-probe impedance spectroscopy. Its current density and power density values are 269 mA cm(-2) and 66 mW cm(-2), respectively. The voltage retention of the B3 membrane was maintained almost at 0.92 V and degradation of voltage after 20 hours in the durability study was about 0.01 V.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 57-13-6, Name is Urea, formurla is CH4N2O.

Chicken meat is rich in unsaturated fatty acids. Therefore, it is more susceptible to lipid oxidation and production of volatile organic compounds (VOC). In this study, we evaluated the fatty acids, antioxidants, and VOC profiles of raw and cooked meat samples derived from 4 strains of chicken differing in their growth rates, which were as follows: slow-growing (SG, Leghorn), medium-growing (MG, Hubbard and Naked Neck), and fast-growing (FG, Ross). The VOC profile of meat was measured using proton-transfer reaction-mass spectrometry (PTR-MS). The VOC were identified using PTR-time of flight-MS (PTR-ToF-MS). The data were analyzed using both univariate and multivariate models. Twenty main VOC were identified, which were classified into the following chemical categories: aldehydes, alka dienes, alkenes, furans, amides, alcohols, and other compounds. Our results revealed that the chicken genotype and the method of cooking strongly influenced the VOC profile of the meat. Identifying the relationships between these traits allowed us to highlight the trade-off of the main substrates such as n-3 and n-6 polyunsaturated fatty acids (PUFA), protective substances (antioxidants), and degradation products (VOC) of the poultry meat produced during cooking. The extent of VOC production and n-3 loss was found to be higher for the SG genotype. Reduction of n-6 was higher in MG, whereas small losses in antioxidants and PUFA were observed in the FG genotype, consequently, resulting in the lowest production of VOC. The SG and MG are genotypes more active from a kinetic point of view respect to the FG ones. For this reason, in the FG genotypes, the antioxidants are less involved in the oxidative stress induced by the movement; thus, they were available to protect the lipid of the meat during the cooking process. These results suggested that the use of SG and MG genotypes requires a specific dietary protocol (i.e., increasing the antioxidants content) to counteract the lipid oxidations in all the phases: in vivo, postmortem, and during/after cooking.

The reduction of ketones by SmI2-water has long been thought to proceed through a reversible initial electron transfer with the formation of organosamarium intermediates in a follow-up step. Kinetic experiments on the reduction of two model ketones and structurally similar ketones with a pendant alkene are shown to be consistent with a rate-limiting reduction by SmI2-water through a proton-coupled electron-transfer (PCET). Literature values for the rates of radical cyclizations and reduction of radicals by SmI2 and thermochemical data for radical reduction by SmI2-water further support a rate-limiting initial step for ketone reductions. These data suggest that discrete organosamarium species may not be intermediates in ketone reductions by SmI2-water.

Structural variations of the benzylphenoxyacetamide (BPA) molecular skeleton were explored as a viable starting point for designing new anti-glioblastoma drug candidates. Hand-to-hand computational evaluation, chemical modifications, and cell viability testing were performed to explore the importance of some of the structural properties in order to generate, retain, and improve desired anti-glioblastoma characteristics. It was demonstrated that several structural features are required to retain the anti-glioblastoma activity, including a carbonyl group of the benzophenone moiety, as well as 4′-chloro and 2,2-dimethy substituents. In addition, the structure of the amide moiety can be modified in such a way that desirable anti-glioblastoma and physical properties can be improved. Via these structural modifications, more than 50 compounds were prepared and tested for anti-glioblastoma activity. Four compounds were identified (HR28, HR32, HR37, and HR46) that in addition to HR40 (PP1) from our previous study, have been determined to have desirable physical and biological properties. These include high glioblastoma cytotoxicity at low mu M concentrations, improved water solubility, and the ability to penetrate the blood brain barrier (BBB), which indicate a potential for becoming a new class of anti-glioblastoma drugs.

Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels. 73-32-5, Name is H-Ile-OH, molecular formula is C6H13NO2. In an article, author is Xiao, Yao,once mentioned of 73-32-5, Category: amides-buliding-blocks.

An air-stable Mg salt, [Mg(MIm)(6)][TFSA](2) [MIm = 1-methylimidazole; TFSA = bis(trifluoromethylsulfonyl)amide], was obtained by recrystallization from the MIm solution of Mg[TFSA](2). This compound melts at 481 K under sealed conditions, whereas it loses MIm at elevated temperatures (448 K, 5% weight loss) under unsealed conditions. The crystal structure of [Mg(MIm)(6)][TFSA](2) was determined by X-ray diffraction. The compound crystallizes in the monoclinic system (space group P2(1)/c) with a = 8.2062(7) angstrom, b = 11.3185(10) angstrom, c = 24.454(2) angstrom, = 90.229(2)degrees, V = 2271.3(3) angstrom(3), and Z = 2. The Mg2+ cation is octahedrally surrounded by six non-methylated N atoms of MIm ligands to form the [Mg(MIm)(6)](2+) complex cation, in which three imidazolium rings are crystallographically independent. The interplanar angles between two imidazolium rings, which are close to 90 degrees in an ideal model, are 64.01(14), 72.86(18), and 81.91(17)degrees owing to the interaction of the [Mg(MIm)(6)](2+) cations with the TFSA(-) anions. The TFSA anion is completely isolated from the Mg2+ core and adopts the energetically favorable trans conformation. Raman spectroscopic measurements revealed the octahedral coordination of MIm to Mg2+ in crystalline [Mg(MIm)(6)][TFSA](2) and MIm solutions of Mg[TFSA](2).

The mechanistic investigation of copper-catalysed transformations has been an important and fundamental task. Herein, we report via XAS and EPR spectroscopy that the sodium bis(trimethylsilyl)amide could reduce Cu(ii) to a Cu(i) species serving as an electron donor. XAS spectroscopy demonstrates that the newly formed Cu(i) species is the Cu[N(TMS)(2)](2)Na ate complex, in which the nitrogen atoms coordinate with copper linearly.
