In this study we describe the reactivity of unsaturated N-alkoxyureas in the presence of different combinations of a hypervalent iodine(III) reagent and a bromide source or TEMPO. Three complementary cyclizations can be achieved depending on the reaction conditions. On the one hand, PIFA with pyridinium bromide leads to an oxybromination reaction. On the other hand, bis(tert-butylcarbonyloxy)iodobenzene with tetrabutylammonium bromide or TEMPO triggers aminobromination or aminooxyamination reactions, respectively. Control experiments showed that the three reactions proceed through distinct mechanisms: the first process is ionic while the other two follow a radical manifold.

Thermal treatment during sea cucumber processing might affect the texture of the final product. In the present study, collagen fibers (CFs) extracted from the body wall of sea cucumber Apostichopus japonicus were used to investigate the effects of heating and oxidative conditions on CFs structure. Hydroxyl radicals (center dot OH) were generated in CFs treated at 37 degrees C and the intensity of the signal was comparable to samples under oxidative conditions at 4 degrees C. Release of protein and glycosaminoglycan was observed in CFs heat-treated at 37 degrees C or under oxidative conditions at 4 degrees C, leading to the conversion of alpha-helixes into beta-sheets, red shift of amide band I, decrease in thermostability, and scattered arrangement of collagen fibrils. The degree of damage in CFs structure is different among groups. In particular, in thermally- and oxidative treated group, macromolecular fragments remarkably degraded over time, 10 kDa proteins were abundantly released, amide bands A and III showed redshift, and maximum denaturation temperature and decomposition temperature were the lowest compared to other groups. The findings discussed herein reveal the structural changes induced by thermal treatment in sea cucumber CFs and provide an explanation of the mechanism from the view of protein oxidation.

Three uranyl amide complexes have been isolated from slow evaporation technique from an aqueous solution of nitric acid (0.5 M), in the presence of N’,N-diethylacetamide (noted dam; compound 1), N-ethylacetamide (noted earn; compound 2) and 2-(2-oxopyrrolidino)acetamide (or piracetam, noted pam; compound 3). It results in the formation of crystalline molecular assemblies of UO2(L)(2)(NO3)(2) neutral moieties (L = amide ligand), in which the uranyl center is coordinated to two chelating nitrate groups either in cis positions (1) or trans positions (2 and 3) and two organic ligands, through the amide functionality. The corresponding coordination geometry for uranyl is a hexagonal bipyramid, with the two typical trans U=O bondings. Single-crystal X-ray diffraction analysis revealed the bond lengths of U-O-amide are found to be for 2.362(3), 2.363(3) and 2.374(2) angstrom for 1, 2 and 3, respectively. The three complexes have been further characterized by infrared spectroscopy and their thermal behavior has been evaluated by thermogravimetry. (C) 2017 Elsevier Ltd. All rights reserved.

We report herein that the Ir and Cu-I bis-metal catalyzed reductive alkynylation of amides, a method that we developed previously, can be extended to 6-, 7-, and 8-membered lactams. The catalytic reductive alkynylation of 6-methyl-2-piperidinones and its 3-benzyloxy derivative proceeded with 2.3:1 to 7:1 2,6-trans/cis diastereoselectivities. The resulting piperidines were converted into alkaloids (+/-)-solenopsin, (+/-)-solenopsin A, and (+)-julifloridine all in only one step. This two-step approach to the alkaloids is much shorter and much efficient than the conventional multistep methods.

Application of 146374-27-8, The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 146374-27-8, Name is 2-Methylpropane-2-sulfinamide, SMILES is CC(C)(C)[S](=O)N, belongs to amides-buliding-blocks compound. In a article, author is Rao, Sadu Nageswara, introduce new discover of the category.

The high cost, potential toxicity, and possible enzyme inhibition ability of artificial mediators have limited the large-scale application of laccase (Lac)/mediator systems. Here, sinapic acid (SA), a natural mediator, was covalently attached to amino-functionalized magnetic nanoparticles (MNPs) via amide bond formation. The as-prepared SA@MNPs were characterized by Fourier-transform infrared spectroscopy, scanning electron microscopy, cyclic voltammetry, and thermogravimetric analysis. The SA@MNPs were then applied to evaluate the activity of the immobilized mediator for Lac-catalyzed dye decolorization using indigo carmine (IC) as a model dye. When SA and SA@MNPs were used as Lac mediators, IC decolorization yields of similar to 93% and 96%, respectively, were obtained after 60 min. Moreover, SA@MNPs exhibited an IC decolorization yield of similar to 90% after being reused for 8 cycles. The Lac/SA@MNP system was shown to degrade IC by breaking down the chromophoric group. The easy recyclability, good reusability, nontoxicity, and relatively low cost of SA@MNPs make this immobilized natural mediator a promising tool for dye treatment.

Understanding the origin of the catalytic power of enzymes has both conceptual and practical importance. One of the most important finding from computational studies of enzyme catalysis is that a major part of the catalytic power is due to the preorganization of the enzyme active site. Unfortunately, misunderstanding of the nontrivial preorganization idea lead some to assume that it does not consider the effect of the protein residues. This major confusion reflects a misunderstanding of the statement that the interaction energy of the enzyme group and the transition state (TS) is similar to the corresponding interaction between the water molecules (in the reference system) and the TS, and that the catalysis is due to the reorganization free energy of the water molecules. Obviously, this finding does not mean that we do not consider the enzyme groups. Another problem is the idea that catalysis is due to substrate preorganization. This more traditional idea is based in some cases on inconsistent interpretation of the action of model compounds, which unfortunately, do not reflect the actual situation in the enzyme active site. The present article addresses the above problems, clarifying first the enzyme polar preorganization idea and the current misunderstandings. Next we take a specific model compound that was used to promote the substrate preorganization proposal and establish its irrelevance to enzyme catalysis. Overall, we show that the origin of the catalytic power of enzymes cannot be assessed uniquely without computer simulations, since at present this is the only way of relating structure and energetics.

The present research describes the synthesis, characterization, in vitro biological and docking evaluation of N,N’-(ethane-1,2-diyl)bis(benzamides) (3a-3j). Consequently, in in vitro hRBCs hemolysis assay, only the bis-amide (3d) induced 52.4% hemolysis at higher concentration (1000 mu g/mL) that decreased drastically with concentration (250 mu g/mL) to 27.9% (CC50 = 400.41). Similarly, the tested bis-amide (3j) was found to be the least toxic with 7.8% hemolysis at higher concentration (1000 mu g/mL) that gradually decreases to 6.1% (CC50 = 19,347.83) at lower concentration (250 mu g/mL). Accordingly, the tested bis-amides were found to be highly biocompatible against hRBCs at higher concentrations with much higher CC50 values (> 1000 mu g/mL). The biocompatible bis-amides (3a-3j) were subjected to in vitro DNA ladder assay to analyze their apoptotic potential. The results obtained suggest the tested bis-amides (3a-3j) are highly degradative toward DNA causing the appearance of more than one bands or complete degradation of DNA except (3a), (3c), (3i) and (3 g). Moreover, the synthesized bis-amides (3a-3j) were tested in in vitro antileishmanial assay to unveil their leishmaniacidal potential. The results obtained clearly indicated that some of the tested bis-amides displayed good dose dependent response. The tested bis-amides were highly active at higher concentration (1000 mu g/mL) against the leishmanial promastigotes and their % inhibitory potential decreased drastically with concentration (250 mu g/mL). Consequently, at higher concentration (1000 mu g/mL), the bis-amide (3f) caused 85% inhibition and was ranked as the most effective leishmaniacidal bis-amides followed by the bis-amide (3 g) with 73.54% inhibition of leishmanial promastigotes. However, in terms of their IC50 values, the best leishmaniacidal potential was displayed by the bis-amide (3f) followed by (3b), (3j) and (3 g) with IC50 values increasing in the order of 633.16, 680.22, 680.22 and 712.93 mu g/mL, respectively. Molecular docking studies revealed that bis-amides having electron-donating groups showed good binding potential against antileishmanial target. [GRAPHICS] .

The arylacetonitrilase from the bacterium Pseudomonas fluorescens EBC191 has been intensively studied as a model to understand the molecular basis for the substrate-, reaction-, and enantioselectivity of nitrilases. The nitrilase converts various aromatic and aliphatic nitriles to the corresponding acids and varying amounts of the corresponding amides. The enzyme has been analysed by site-specific mutagenesis and more than 50 different variants have been generated and analysed for the conversion of (R,S)-mandelonitrile and (R,S)-2-phenylpropionitrile. These comparative analyses demonstrated that single point mutations are sufficient to generate enzyme variants which hydrolyse (R,S)-mandelonitrile to (R)-mandelic acid with an enantiomeric excess (ee) of 91% or to (S)-mandelic acid with an ee-value of 47%. The conversion of (R,S)-2-phenylpropionitrile by different nitrilase variants resulted in the formation of either (S)- or (R)-2-phenylpropionic acid with ee-values up to about 80%. Furthermore, the amounts of amides that are produced from (R,S)-mandelonitrile and (R,S)-2-phenylpropionitrile could be changed by single point mutations between 2%-94% and <0.2%-73%, respectively. The present study attempted to collect and compare the results obtained during our previous work, and to obtain additional general information about the relationship of the amide forming capacity of nitrilases and the enantiomeric composition of the products. 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 146374-27-8, in my other articles.
