Determination of the gauche effect of 3-acetamido- and 3-acetoxy-piperidine and -tetrahydropyran by 1H-n.m.r. spectroscopy

The A-values of the acetamido and the acetoxy group were determined by low-temperature 1H-n.m.r. spectroscopy.The limiting values for the relevant vicinal coupling constants of the newly prepared trans- (22) and cis-5-acetoxy-2-(1-hydroxy-1-methylethyl)tetrahydropyran (24) were obtained at room temperature.The attractive gauche effect of AcNH-3 and AcO-3 in piperidines, piperidinium trifluoroacetates, and tetrahydropyrans was investigated by 1H-n.m.r. spectroscopy both at low temperature (integrals) and at room temperature (band widths and coupling constants).The results obtained at low temperature are more reliable.The position of the conformational equilibrium of N-(3-piperidyl)acetamide (11), N-(1-methyl-3-piperidyl)acetamide (12), and N-(tetrahydropyran-3-yl)acetamide (17) depends strongly upon the nature of the solvent and, in apolar solvents, upon the concentration.

Synthesis and biological evaluation of some furanones as putative chitinase inhibitors

Analogs of naturally occurring furanones that were reported to be weak inhibitors of Serratia marcescens chitinases were prepared and tested towards various chitinases. Some of these compounds – but not the natural products – were found to be weak but selective inhibitors; all glycosylated analogs tested were inactive. Activation of the plant enzyme hevamine was observed in one case, which is unusual. Georg Thieme Verlag Stuttgart.

Stereospecific Synthesis of E-Alkenes through Anti-Markovnikov Hydroalkylation of Terminal Alkynes

We have developed a method for stereospecific synthesis of E-alkenes from terminal alkynes and alkyl iodides. The hydroalkylation reaction is enabled by a cooperative action of copper and nickel catalysts and proceeds with excellent anti-Markovnikov selectivity. We demonstrate the broad scope of the reaction, which can be accomplished in the presence of esters, nitriles, aryl bromides, ethers, alkyl chlorides, anilines, and a wide range of nitrogen-containing heteroaromatic compounds. Mechanistic studies provide evidence that the copper catalyst activates the alkyne by hydrocupration, which controls both the regio- and diastereoselectivity of the overall reaction. The nickel catalyst activates the alkyl iodide and promotes cross coupling with the alkenyl copper intermediate.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2081-44-9 is helpful to your research., Electric Literature of 2081-44-9

Enzymatic characterization and molecular modeling of an evolutionarily interesting fungal beta-N-acetylhexosaminidase

Fungal beta-N-acetylhexosaminidases are inducible extracellular enzymes with many biotechnological applications. The enzyme from Penicillium oxalicum has unique enzymatic properties despite its close evolutionary relationship with other fungal hexosaminidases. It has high GalNAcase activity, tolerates substrates with the modified N-acyl group better and has some other unusual catalytic properties. In order to understand these features, we performed isolation, biochemical and enzymological characterization, molecular cloning and molecular modelling. The native enzyme is composed of two catalytic units (65 kDa each) and two propeptides (15 kDa each), yielding a molecular weight of 160 kDa. Enzyme deglycosylated by endoglycosidase H had comparable activity, but reduced stability. We have cloned and sequenced the gene coding for the entire hexosaminidase from P. oxalicum. Sufficient sequence identity of this hexosaminidase with the structurally solved enzymes from bacteria and humans with complete conservation of all catalytic residues allowed us to construct a molecular model of the enzyme. Results from molecular dynamics simulations and substrate docking supported the experimental kinetic and substrate specificity data and provided a molecular explanation for why the hexosaminidase from P. oxalicum is unique among the family of fungal hexosaminidases.

Extra Sugar on Vancomycin: New Analogues for Combating Multidrug-Resistant Staphylococcus aureus and Vancomycin-Resistant Enterococci

Lipophilic substitution on vancomycin is an effective strategy for the development of novel vancomycin analogues against drug-resistant bacteria by enhancing bacterial cell wall interactions. However, hydrophobic structures usually lead to long elimination half-life and accumulative toxicity; therefore, hydrophilic fragments were also introduced to the lipo-vancomycin to regulate their pharmacokinetic/pharmacodynamic properties. Here, we synthesized a series of new vancomycin analogues carrying various sugar moieties on the seventh-amino acid phenyl ring and lipophilic substitutions on vancosamine with extensive structure-activity relationship analysis. The optimal analogues indicated 128-1024-fold higher activity against methicillin-susceptible S. aureus, vancomycin-intermediate resistant S. aureus (VISA), and vancomycin-resistant Enterococci (VRE) compared with that of vancomycin. In vivo pharmacokinetics studies demonstrated the effective regulation of extra sugar motifs, which shortened the half-life and addressed concerns of accumulative toxicity of lipo-vancomycin. This work presents an effective strategy for lipo-vancomycin derivative design by introducing extra sugars, which leads to better antibiotic-like properties of enhanced efficacy, optimal pharmacokinetics, and lower toxicity.

A Combined Chemical and Enzymatic Strategy for the Construction of Carbohydrate-Containing Antigen Core Units

Glycosidase-mediated coupling of glycal acceptors with galactose donors affords beta-1,3-linked dissacharides that are versatile intermediates for further chemical and enzymatic manipulation.The utility of these disaccharides is demonstrated by the elaboration of these compounds into type I and type IV core disaccharides of carbohydrate-containing antigens.Further conversion of the type IV dissacharide to a mucin-type trisaccharide (Galbeta1,3(GlcNAcbeta1,6)GalNAc) was accomplished with the use of a beta-1,6-N-acetylglucosaminyltransferase.This combined use of enzymatic andchemical methodologies allows for the rapid assembly, with high regio- and stereoselectivity, of core oligosaccharides of biologically important glycoconjugates.

Azetidine and Piperidine Carbamates as Efficient, Covalent Inhibitors of Monoacylglycerol Lipase

Monoacylglycerol lipase (MAGL) is the main enzyme responsible for degradation of the endocannabinoid 2-arachidonoylglycerol (2-AG) in the CNS. MAGL catalyzes the conversion of 2-AG to arachidonic acid (AA), a precursor to the proinflammatory eicosannoids such as prostaglandins. Herein we describe highly efficient MAGL inhibitors, identified through a parallel medicinal chemistry approach that highlighted the improved efficiency of azetidine and piperidine-derived carbamates. The discovery and optimization of 3-substituted azetidine carbamate irreversible inhibitors of MAGL were aided by the generation of inhibitor-bound MAGL crystal structures. Compound 6, a highly efficient and selective MAGL inhibitor against recombinant enzyme and in a cellular context, was tested in vivo and shown to elevate central 2-AG levels at a 10 mg/kg dose.
