The rapid emergence and spread of multi-resistant bacteria have created an urgent need for new antimicrobial agents. We report here a series of amphipathic alpha,alpha-disubstituted beta-amino amide derivatives with activity against 30 multi-resistant clinical isolates of Gram-positive and Gram-negative bacteria, including isolates with extended spectrum beta-lactamase – carbapenemase (ESBL-CARBA) production. A variety of halogenated aromatic side-chains were investigated to improve antimicrobial potency and minimize formation of Phase I metabolites. Net positive charge and cationic character of the derivatives had an important effect on toxicity against human cell lines. The most potent and selective derivative was the diguanidine derivative 4e with 3,5-di-brominated benzylic side-chains. Derivative 4e displayed minimum inhibitory concentrations (MIC) of 0.25-8 mu g/mL against Gram-positive and Gram-negative reference strains, and 2-32 mu g/mL against multi-resistant clinical isolates. Derivative 4e showed also low toxicity against human red blood cells (EC50 > 200 pg/mL), human hepatocyte carcinoma cells (HepG2: EC50>64 mu g/mL), and human lung fibroblast cells (MRC-5: EC50 > 64 mu g/mL). The broad-spectrum antimicrobial activity and low toxicity of diguanylated derivatives such as 4e make them attractive as lead compounds for development of novel antimicrobial drugs.

N-15 R-2 relaxation measurements are key for the elucidation of the dynamics of both folded and intrinsically disordered proteins (IDPs). Here we show, on the example of the intrinsically disordered protein -synuclein and the folded domain PDZ2, that at physiological pH and near physiological temperatures amidewater exchange can severely skew Hahn-echo based N-15 R-2 relaxation measurements as well as low frequency data points in CPMG relaxation dispersion experiments. The nature thereof is the solvent exchange with deuterium in the sample buffer, which modulates the N-15 chemical shift tensor via the deuterium isotope effect, adding to the apparent relaxation decay which leads to systematic errors in the relaxation data. This results in an artificial increase of the measured apparent N-15 R-2 rate constantswhich should not be mistaken with protein inherent chemical exchange contributions, R-ex, to N-15 R-2. For measurements of N-15 R-2 rate constants of IDPs and folded proteins at physiological temperatures and pH, we recommend therefore the use of a very low D2O molar fraction in the sample buffer, as low as 1%, or the use of an external D2O reference along with a modified N-15 R-2 Hahn-echo based experiment. This combination allows for the measurement of R-ex contributions to N-15 R-2 originating from conformational exchange in a time window from mu s to ms.

Electrolyte solutions are one of the key liquid materials in the development of high-performance lithium-ion batteries (LIBs). Recently, a new concept, superconcentrated electrolyte, i.e., solvent-in-salt in liquid state, was proposed and widely investigated in terms of not only electrochemistry, but also physical chemistry and/or solution chemistry. In this work, we report on a structural study of lithium-ion complexes in highly salt-concentrated electrolytes, lithium bis(trifluoromethanesulfonyl)amide (LiTFSA) salt in N,N-dimethylpropionamide (DMPA), using Raman spectroscopy with the aid of density functional theory (DFT) calculations. In the range of the Li salt concentration, c(Li) = 0 – 3.2 mol dm(-3), the individual solvation numbers of DMPA and TFSA species around Li ions [n((DMPA)) and n((TFSA)), respectively] were quantitatively determined and the relation between the Li ion complex structure and c(Li) was discussed at the molecular level.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. Category: amides-buliding-blocks, 123-39-7, Name is N-Methylformamide, SMILES is O=CNC, in an article , author is Sohail, Amir, once mentioned of 123-39-7.

In this work, a novel phenethylamine-derived protecting group is introduced, which is able to significantly enhance the Grubbs I-catalyzed formation of 9- to 12-membered lactams through charge-induced conformational fixation under acidic conditions. As the new approach is particularly valuable for 10- and 11-membered ring systems, for which no related precedence was available so far, the overall strategy now offers general access to medium-sized lactams via ring closing metathesis. Cleavage of the protecting group can be achieved through a mild sequence combining N-oxidation and Cope elimination or alternatively under standard hydrogenation conditions.

Toward the development of selective cyclooxygenase-2 inhibitors, a series of pyrrolidine derivatives is described. All the compounds containing sulfonamide, ester, nitrile, acid, amide and urea functionalities were computationally screened, and binding affinity scores for all synthesized compounds with cyclooxygenase-1 and cyclooxygenase -2 were compared. The computational observations showed three top-ranked compounds (8b, 8d and 10a) having selectively more affinity for cyclooxygenase -2. These were selected for pharmacological evaluation using carrageenan-induced rat paw edema model. Compound 8b showed maximum activity (54.83%) which was closer to standard drug indometacin (57.48%). The safety parameter of the potent compound (8b) was assessed using aspirin induced gastric ulceration animal model. [GRAPHIC].

The composition and the interaction of the suspended particulate matter (SPM) with metal ions, along with the presence and characteristics of microplastics, were analyzed for the first time in the water column of the inner zone of Bahia Blanca Estuary during winter (June, July, and August) 2019. Surface analysis techniques (Scanning Electron Microscopy combined with Energy Dispersive X-ray Spectroscopy, X-ray Photoelectron Spectroscopy, and X-ray Diffraction) were employed to obtain an in-depth characterization of the particulate matter, suggesting the presence of Fe in our samples, with a mixture of Fe3+/Fe2+ oxidation states. Microplastics ranged in concentrations between 3 and 11.5 items L-1, with an average of 6.50 items L-1 (S.E:+/- 4.01), being fibers the most abundant type. Infrared Spectroscopy suggests that these fibers correspond to semi-synthetic cellulose-based and poly(amide) remains. We concluded that the SPM is a significant vehicle for metals which might have adverse effects on marine organisms. (C) 2020 Elsevier B.V. All rights reserved.

Carboxylic acid reductases (CARs) catalyze the reduction of a broad range of carboxylic acids to aldehydes using the cofactors adenosine triphosphate and nicotinamide adenine dinucleotide phosphate, and have become attractive biocatalysts for organic synthesis. Mechanistic understanding of CARs was used to expand reaction scope, generating biocatalysts for amide bond formation from carboxylic acid and amine. CARs demonstrated amidation activity for various acids and amines. Optimization of reaction conditions, with respect to pH and temperature, allowed for the synthesis of the anticonvulsant ilepcimide with up to 96% conversion. Mechanistic studies using site-directed mutagenesis suggest that, following initial enzymatic adenylation of substrates, amidation of the carboxylic acid proceeds by direct reaction of the acyl adenylate with amine nucleophiles.

In a document, author is Hu, Qiyan.

The linear tridentate sp(3)P/sp(3)NH/sp(2)N ligand PN(H)N ((R)-2′-(diphenylphosphino)-N-(pyridin-2-ylmethyl)[1,1′- binaphthalen]-2-amine) exclusively forms fac[Ru(PN(H)N)(dmso)(3)](BF4)(2) over the mer isomer with the help of the three strongly pi-accepting DMSO ligands. The three different ligating atoms exert a divergent effect on the trans-DMSO Ru bond strengths, enabling the stereo selective generation of fac-RuH(CH3O)(PN(H)N)(dmso) (RuNH). RuNH efficiently hydrogenates both nonchelatable t-butyl methyl ketone (BMK) and chelatable t-butyl methoxycarbonylmethyl ketone (BMCK) in the presence of a catalytic amount of CH3OK. The reaction proceeds at the H-sp(3)N-Ru-H bifunctional reaction site of fac-RuH2(PN(H)N)(dmso), and high enantioselectivity is attained in a chiral 3D cavity constructed by the sp(3)N trans DMSO, the conformation of which is fixed by a PyC(6)H-O=S hydrogen bond. We determined the structures of RuNH, the K amide RuNK, Ru dihydride, and Ru amido species by detailed NMR analysis using N-15-labeled PN(H)N and C(3)-Ph-substituted PN(H)N. The rate of BMK hydrogenation is significantly affected by [CH3OK](0), showing a characteristic curve with a peak followed by a pseudo-minus-first-order decay. The RuNH is easily deprotonated by CH3OK to generate RuNK, which is less reactive but has the same enantioface discrimination ability. Increased contribution of the slow RuNK cycle decreases the rate at higher [CH3OK](0). The RuNH- and RuNK-involved dual catalytic cycle is supported by curve-fitting analyses and K+ trapping experiments. In hydrogenation of BMCK, only the RuNH cycle operates because BMCK is preferentially deprotonated over RuNH.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 123-39-7, in my other articles.
