A selective copper(I)-catalyzed benzylic C(sp(3))-H geminal difunctionalization reaction of a benzylic-type sp(3) carbon was developed. This novel strategy allowed simultaneous introduction of amide and hydroxyl group in a highly selective and efficient way via successive oxidative intramolecular amidation and hydroxylation. This method was also applied to the synthesis of 3-hydroxy-2,3-dihydro-1H-pyrrolo[3,4-b]quinoxalinones from readily available 3-methyl-N-substituted quinoxaline-2-carboxamides in moderate to good yields. The five-membered cyclic hemiaminal moiety of the pyrrolo[3,4-b]quinoxalinones can serve as an intermediates for subsequent transformations into other useful functional groups. (C) 2018 Elsevier Ltd.

Formation of gas hydrates is a problem in the petroleum industry where the gas hydrates can cause blockage of the flowlines. Kinetic hydrate inhibitors (KHIs) are water-soluble polymers, sometimes used in combination synergistically or with nonpolymeric synergists, that are used to prevent gas hydrate blockages. They have been used in the field successfully since 1995. In this paper, we present the first KHI results for the polymer, poly(3-methylene-2-pyrrolidone) (P(3M2P)), which is structurally similar to poly(N-vinylpyrrolidone) (PVP), one of the first KHIs to be discovered. 3M2P polymers with different molecular weights (5500 and 2500 g/mol) and at different concentrations (2500, 5000, and 7500 ppm) were investigated for their KHI performance on structure II hydrates in high-pressure rocking cells. We also investigated the synergistic effect of P(3M2P) with n-butyl glycol ether (BGE), a known synergist for some KHI polymers. At the lower concentrations, P(3M2P) gives a similar performance to PVP (M-w = 8000-9000 g/mol). However, PVP outperforms both samples of P(3M2P) at 7500 ppm, with and without BGE. We suggest that the reasons for the performance level of P(3M2P) are related to greater resonance stabilization of the amide group in P(3M2P) compared to PVP. Also, the pyrrolidone ring of the PVP repeat unit has a larger hydrophobic sequence of three methylene units compared to the two methylene units in the pyrrolidone ring of P(3M2P). This relates well to previous studies where larger hydrophobic groups are preferable in KHI polymers as long as they are water-soluble at hydrate-forming temperatures.

Preorganization and aggregation in photoredox catalysis can significantly affect reactivities or selectivities but are often neglected in synthetic and mechanistic studies, since the averaging effect of flexible ensembles can effectively hide the key activation signatures. In addition, aggregation effects are often overlooked due to highly diluted samples used in many UV studies. One prominent example is Knowles’s acceleration effect of thiophenol in proton-coupled electron transfer mediated hydroamidations, for which mainly radical properties were discussed. Here, cooperative reactivity enhancements of thiophenol/disulfide mixtures reveal the importance of H-bond networks. For the first time an in-depth NMR spectroscopic aggregation and H-bond analysis of donor and acceptor combined with MD simulations was performed revealing that thiophenol acts also as an acid. The formed phosphate-H+-phosphate dimers provide an extended H-bond network with amides allowing a productive regeneration of the photocatalyst to become effective. The radical and acidic properties of PhSH were substituted by Ph2S2 and phosphoric acid. This provides a handle for optimization of radical and ionic channels and yields accelerations up to 1 order of magnitude under synthetic conditions. Reaction profiles with different light intensities unveil photogenerated amidyl radical reservoirs lasting over minutes, substantiating the positive effect of the H-bond network prior to radical cyclization. We expect the presented concepts of effective activation via H-bond networks and the reactivity improvement via the separation of ionic and radical channels to be generally applicable in photoredox catalysis. In addition, this study shows that control of aggregates and ensembles will be a key to future photocatalysis.

Background: Glycosylation of proteins is the most common, multifaceted co- and post-translational modification responsible for many biological processes and cellular functions. Significant alterations and aberrations of these processes are related to various pathological conditions, and often turn out to be disease biomarkers. Conventional N-glycosylation occurs through the recognition of the consensus sequon, asparagine (Asn)-X-serine (Ser)/threonine (Thr), where X is any amino acid except for proline, with N-acetylglucosamine (GlcNAc) as the first glycosidic linkage. Usually, O-glycosylation adds a glycan to the hydroxyl group of Ser or Thr beginning with N-acetylgalactosamine (GalNAc). Scope of review: Protein glycosylation is further governed by additional diversifications in sequon and structure, which are yet to be fully explored. This review mainly focuses on the occurrence of N-glycosylation in non consensus motifs, where Ser/Thr at the +2 position is substituted by other amino acids. Additionally, N-glycosylation is also observed in other amide/amine group-containing amino acids. Similarly, O-glycosylation occurs at hydroxyl group-containing amino acids other than serine/threonine. The neighbouring amino acids and local structural features around the potential glycosylation site also play a significant role in determining the extent of glycosylation. All of these phenomena that yield glycosylation at the atypical sites are reported in a variety of biological systems, including different pathological conditions. Conclusion and Significance: Therefore, the discovery of more novel sequence patterns for N- and O-glycosylation may help in understanding the functions of complex biological processes and cellular functions. Taken together, all these information provided in this review would be helpful for the biological readers.

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.

To get a better understanding on the molecular basis of the cytotoxicity of PEI which has been considered as golden standard for polymeric gene delivery carriers. Dynamic light scattering, fluorescence spectra, zeta. potential measurement and isothermal titration calorimetry were conducted to reveal the mechanism of interaction between PEIs( average molecular weight of 25000, 10000 and 1800) and 1,2-dioleoyl-sn-glycero-3-phosphatidylcholine( DOPC) liposome. The influence on the polarity of microenvironment and the permeability of liposome bilayer were also investigated. The result showed that PEI bound to DOPC vesicles via hydrogen bond or van Waals interactions between the amide groups and the phosphorylcholine heads. The complex formation with PEI induced aggregation and increase in zeta potential of liposomes at low PEI concentration up to 0.075 mg/mL. A further increase in PEI concentration made little change on the sur. face potential, however reduced the aggregation of the vesicle due to the repulsion between the adsorbed PEI chains. PEI binding decreased the packing density of hydrocarbon chain of lipid molecules and the hydropho. bicity in the bilayer membrane, and thus resulted in an enhanced permeability of calcein and quercetin through the membrane. The polymer size played an important role in PEI. DOPC liposome interaction. PEI with higher molecular weight was more favorable to interact with DOPC and more efficient to perturb the structural properties of the membrane.

Under catalyst-free conditions, an efficient method for the synthesis of 2-aminopyridine derivatives through the nucleophilic substitution and hydrolysis of 2-fluoropyridine and acetamidine hydrochloride has been developed. This amination uses inexpensive acetamidine hydrochloride as the ammonia source and has the advantages of a high yield, high chemoselectivity and wide substrate adaptability. The results suggest that other N-heterocycles containing fluorine substituents can also complete the reaction via these reaction conditions and yield the target products.

The incidence of invasive bacterial infections has increased remarkably over the past two decades, which was mainly attributed to the increasing emergence of drug-resistant bacteria especially multidrug-resistant strains, intractable pathogens and newly arising pathogenic organisms. Tetrazoles, the bioisoster of carboxylic acid, possess considerable antibacterial property. Hybridization of tetrazole with other antibacterial pharmacophores has the potential to enhance the efficacy against both drug-sensitive and drug-resistant pathogens. Some tetrazole hybrids such as tetrazole-oxazolidinone hybrid Tedizolid 25 and Tedizolid phosphate 26 have already been marketed for the treatment of acute bacterial skin and skin structure infections caused by various bacteria. DA-7867 (27), the amide analog of Tedizolid, also exhibited promising activities against a panel of clinically important pathogens including drug-resistant organisms, demonstrating the possible utility of the tetrazole scaffolds in the development of new antibacterial agents. Thus, hybridization of tetrazole with other antibacterial pharmacophores represents a promising strategy to develop novel antibacterial candidates. This work is attempted to systematically review the research of tetrazole hybrids in the design and development of antibacterial agents during the past two decades. The structure-activity relationship (SAR) is also discussed to provide an insight for rational design of more effective tetrazole antibacterial candidates. (C) 2019 Elsevier Masson SAS.

Context: Matrix metalloproteinases (MMPs) are a family of proteolytic enzymes, the zinc-dependent endopeptidases involved in the degradation of extracellular matrix (ECM) and releasing growth factors and cytokines residing in ECM. Amongst 23 types of MMPs, an isomer called MMP-9 has been found to play a vital role in angiogenesis, and its overexpression leads to cancer. Inhibition of MMP-9 could be very useful for the treatment of cancer. Objectives: The present work consists of design, synthesis and cell viability assay of a series of caffeic acid derivatives as anticancer agents. Methods: A convergent method was followed in order to synthesize caffeic acid derivatives using microwave assisted synthesis. All the synthesized compounds were studied by docking to determine the binding interactions for the best fit conformations in the binding site of MMP-9 protein and based the docking results, seven compounds were evaluated as anticancer agents by in vitro cell viability assay. Results: Compounds 2, 4, 8, 9, 14, 15 and 21 showed inspiring interactions with MMP-9 enzyme in silico docking studies. In the in vitro cell viability assay, compound 15 was found as the most potent amongst selected caffeic acid derivatives. Conclusion: These newly designed molecules thus can act as starting hits for the design of new and effective inhibitors of MMP-9 for the potential treatment of cancer. (C) 2017 Future University.
