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.

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.

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.

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.

Rapid and sensitive detection technology is the key to preventing food-borne disease outbreaks. In this study, a low-field nuclear magnetic resonance (NMR) biosensor based on polyamidoamine dendrimers was prepared for the rapid detection of Salmonella in milk. The polyamidoamine dendrimer was biotinylated by amide reaction and chelated to diethylene triamine pentacetate acid and gadolinium to form magnetic complexes. The antibody and magnetic complexes were combined through a streptavidin-biotin system using streptavidin as an intermediate bridge to obtain the immunoprobe. Salmonella was captured by the irnmunoprobe via antigen-antibody interaction and then separated from the mixture by membrane filtration. Finally, the longitudinal relaxation signal of the filtrate was obtained by NMR. The biosensor had excellent anti-interference capability and could detect Salmonella within 1.5 h at a sensitivity of 10(3) cfu mL(-1). This method based on NMR can realize detection in complex samples and has the potential to be a quick and nondestructive method for detecting target bacteria.

Herein, a divergent synthesis of a variety of 2 alpha- and 5 alpha-substituted furan derivatives from 2-hydroxy-1,4-diones is reported. By using appropriate substrates and an acid catalyst, the reactions occurred selectively through cyclization/1,6-conjugate addition or cyclization/Friedel-Crafts-type cascade reactions. A broad range of nucleophilic reagents (>10 types for the 1,6-conjugate addition for 5 alpha substitution and >20 types for the Friedel-Crafts-type cascade reaction for 2 alpha substitution), including alcohols, amides, furan, thiophene, pyrrole, indole, phenols, and many others, can successfully participate in the reactions, providing a universal strategy for a diversity-oriented synthesis of alpha-substituted furan derivatives. Deuteriation experiments and DFT calculations were carried out to support the proposed reaction mechanisms. Antifungal activity experiments revealed that products with an indole or 4-hydroxycoumarin core substituted at the 2 alpha position showed moderate activities against Rhizoctorzia solani and Botrytis cinerea, respectively.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 127-19-5, Name is N,N-Dimethylacetamide, molecular formula is C4H9NO.

Hydrogen desorption properties of Li-N-H system (composed of LiH + LiNH2) doped with LiBH4 as catalyst and microwave absorber have been investigated under microwave irradiation. The results showed that pure Li-N-H system can not be heated effectively by microwave irradiation, but it can be rapidly heated up to 500 degrees C within 5 min with 7.6 wt.% LiBH4 addition by a microwave heating with a power of 400 W. Further study indicates that it is Li4BN3H10 generated during the ball milling process that acts as the microwave absorber and catalyst. Li-N-H +7.6 wt% LiBH4 by microwave heating desorbed 4.95 wt.% hydrogen which is 3.6 times more than that of Li-N-H +7.6 wt.% graphite by electric resistance heating at 250 degrees C within 30 min, indicating that the desorption kinetics of Li-N-H system is improved by the combination of the catalytic effect of Li4BN3H10 and microwave irradiation. Furthermore, the isothermal kinetics of Li-N-H with 7.6 wt.% LiBH4 under microwave irradiation were well fitted by Johnson-Mehl-Avrami-Kolmogorov (JMAK) model and the activation energy was 43.9 kJ/mol H-2 which is significantly lower than that under electric resistance heating, demonstrating that the desorption kinetics of Li-N-H with LiBH4 addition could be effectively improved by microwave irradiation.

Herein we describe the continued optimization of M-4 positive allosteric modulators (PAMs) within the 5-amino-thieno[2,3-c] pyridazine series of compounds. In this letter, we disclose our studies on tertiary amides derived from substituted azetidines. This series provided excellent CNS penetration, which had been challenging to consistently achieve in other amide series. Efforts to mitigate high clearance, aided by metabolic softspot analysis, were unsuccessful and precluded this series from further consideration as a preclinical candidate. In the course of this study, we found that potassium tetrafluoroborate salts could be engaged in a tosyl hydrazone reductive cross coupling reaction, a previously unreported transformation, which expands the synthetic utility of the methodology.

Water self-association dominates the formation of microsolvated molecular clusters which may give rise to complex structures resembling those of pure water clusters. We present a rotational study of the complex formamide-(H2O)(3) formed in a supersonic jet and several monosubstituted isotopologues. Formamide and water molecules form a four-body sequential cycle through N-H center dot center dot center dot O, O-H center dot center dot center dot O, and O-H center dot center dot center dot O=C hydrogen bonds, resulting in a chiral structure with a nonplanar skeleton that can be overlapped to that of water pentamer. The analysis of the N-nucleus quadrupole coupling effects shows the depletion of the electron density of the N atom lone pair with respect to the bare formamide that affects the amide group C-N and C=O distances. The study of the observed tunneling doublets shows that formamide (H2O)(3) follows a path to invert its structure driven by the flipping of water subunits and passing through successive nonplanar configurations, a motion reminiscent of the pseudorotation of water pentamer.

In the present study, three series of novel celastrol derivatives were designed and synthesised by modifying the carboxylic add at the 20th position with amino acid, amine, and triazole derivatives. All the synthesised compounds were screened for their anticancer activities using MTT assay against AGS, MGC-803, SGC-7901, HCT-116, A549, HeLa, BEL-7402, and HepG-2 cell lines. Most of the synthesised compounds exhibited potent antiproliferative effects. The most promising compound 3-Hydroxy-9 beta,13 alpha-dimethyl-2-oxo-24,25,26-trinoroleana-1(10),3,5,7-tetraen-29-oic amide, N-(R)-methyl-3-(1H-indol-2-yl)propanoate (11) showed considerable high anticancer activity against AGS cell lines, with an IC50 value of 0.44 mu M, and considerably higher activities against HCT-116, BEL-7402, and HepG-2 cell lines, with IC50 values of 0.78, 0.63, and 0.76 mu M, respectively. The results of apoptosis tests and molecular docking study of compound 11 binding to Caspase-3 revealed that its mechanism of action with antiproliferative was possibly involved in inducing apoptosis by inducing the activation of caspase-3.
