N-Acylation of Oxazolidinones via Aerobic Oxidative NHC Catalysis

The first N-acylation of synthetically useful oxazolidinones with aldehydes using aerobic oxidative NHC catalysis is reported. The reaction offers a broad scope of functionalized oxazolidinones in good to excellent yields. Careful choice of electron transfer mediators proved pivotal to achieve efficient aerobic N-acylation, which has previously proven difficult using NHC catalysis. The methodology allows a mild entry to acylated oxazolidinones, avoiding the use of hazardous and reactive prefunctionalized substrates.

SYNTHESIS OF N-TRIPEPTIDYL-D-GLUCOSAMINE BY THE STEPWISE REACTION OF N-CARBOXY alpha -AMINO ACID ANHYDRIDE.

N-Peptidyl-D-glucosamines were synthesized by the stepwise reaction of N-carboxy alpha -amino acid anhydrides (4-alkyl-2,5-oxazolidinediones) with D-glucosamine hydrochloride in the presence of equimolar sodium methoxide in a mixture of acetonitrile and methanol, or in methanol, at a low temperature. Polymerization reaction of N-carboxy alpha -amino acid anhydrides (NCAs) did not occur at minus 50 degree C. The mechanism of the reaction was then studied.

Bioisosteric replacement and related analogs in the design, synthesis and evaluation of ligands for muscarinic acetylcholine receptors

Previous structure-activity relationship studies involving a series of lactone-based muscarinic ligands identified a lead compound containing a diphenylmethylpiperazine moiety (4; IC50 = 340 nM). The purpose of the present work is to investigate 1,3-benzodioxoles, 4,4-diethyl substituted tetrahydrofurans, 5-substituted oxazolidinones and chromones as bioisosteric replacements for the lactone ring in a novel series of muscarinic ligands. The approach provided compounds with improved % inhibition values and identified a non-selective muscarinic ligand with an IC50 value of 280 nM. The structure-activity relationship for this new series will be discussed. Selected compounds were evaluated in preliminary assays for subtype selectivity and were found to be non-selective.

In utero exposure to a cardiac teratogen causes reversible deficits in postnatal cardiovascular function, but altered adaptation to the burden of pregnancy

Congenital heart defects (CHD) are the most common birth anomaly and while many resolve spontaneously by 1 year of age, the lifelong burden on survivors is poorly understood. Using a rat model of chemically induced CHD that resolve postnatally, we sought to characterize the postnatal changes in cardiac function, and to investigate whether resolved CHD affects the ability to adapt to the increased the cardiovascular (CV) burden of pregnancy. To generate rats with resolved CHD, pregnant rats were administered distilled water or dimethadione (DMO) [300 mg/kg b.i.d. on gestation day (gd) 9 and 10] and pups delivered naturally. To characterize structural and functional changes in the heart, treated and control offspring were scanned by echocardiography on postnatal day 4, 21, and 10-12 weeks. Radiotelemeters were implanted for continuous monitoring of hemodynamics. Females were mated and scanned by echocardiography on gd12 and gd18 during pregnancy. On gd18, maternal hearts were collected for structural and molecular assessment. Postnatal echocardiography revealed numerous structural and functional differences in treated offspring compared with control; however, these resolved by 10-12 weeks of age. The CV demand of pregnancy revealed differences between treated and control offspring with respect to mean arterial pressure, CV function, cardiac strain, and left ventricular gene expression. In utero exposure to DMO also affected the subsequent generation. Gd18 fetal and placental weights were increased in treated F2 offspring. This study demonstrates that in utero chemical exposure may permanently alter the capacity of the postnatal heart to adapt to pregnancy and this may have transgenerational effects.

Decarboxylative sp 3 C-N coupling via dual copper and photoredox catalysis

Over the past three decades, considerable progress has been made in the development of methods to construct sp 2 carbon-nitrogen (C-N) bonds using palladium, copper or nickel catalysis 1,2 . However, the incorporation of alkyl substrates to form sp 3 C-N bonds remains one of the major challenges in the field of cross-coupling chemistry. Here we demonstrate that the synergistic combination of copper catalysis and photoredox catalysis can provide a general platform from which to address this challenge. This cross-coupling system uses naturally abundant alkyl carboxylic acids and commercially available nitrogen nucleophiles as coupling partners. It is applicable to a wide variety of primary, secondary and tertiary alkyl carboxylic acids (through iodonium activation), as well as a vast array of nitrogen nucleophiles: nitrogen heterocycles, amides, sulfonamides and anilines can undergo C-N coupling to provide N-alkyl products in good to excellent efficiency, at room temperature and on short timescales (five minutes to one hour). We demonstrate that this C-N coupling protocol proceeds with high regioselectivity using substrates that contain several amine groups, and can also be applied to complex drug molecules, enabling the rapid construction of molecular complexity and the late-stage functionalization of bioactive pharmaceuticals.

Bacteria isolated from kidney recipients with urinary tract infections: Epidemiology and susceptibility of the strains

Purpose: The incidence, type, and frequency of antimicrobial resistance of bacteria isolated from kidney recipients with bacterial urinary tract infections (UTIs) was evaluated. Methods: From 2007 to 2015, 1307 consecutive kidney recipients were studied retrospectively for patient demographics, clinical characteristics and urine culture data. Results: A total of 86 (6.6%) patients experienced 102 culture-proved bacterial UTI episodes. Three (3.5%) septic shocks occurred in these 86 patients and 1(1.2%) patients developed UTI-related mortality. The most frequently isolated species were Gramnegative bacteria (68.6%) with E.coli (42.2%) being the most prevalent bacterium. The Gram-negative bacteria were highly resistant to 1st- and 2nd-generation cephalosporin, monocyclic beta lactam and relatively sensitive to meropenem, amikacin and cefoperazone/ sulbactam, with the resistance rates of 85.7%, 85.7%, 81.4%, 21.4%, 21.4% and 28.6%, respectively. More than half (71.4%, 50/70) of Gram-negative bacteria were caused by extended-spectrum beta-lactamase (ESBL) producing strains. All Gram-positive bacteria were susceptible to teicoplanin and linezolid whereas 12.5% of them were resistant to vancomycin. Conclusions: The Gram-negative bacteria were relatively susceptible to meropenem, amikacin and cefoperazone/sulbactam and most of Gram-positive bacteria were susceptible to glycopeptides and oxazolidone. The majority of Gram-negative bacteria were ESBL+ strains and vancomycin-resistant enterococci accounted for 13.6% of all enterococci.

Results from MEA Degradation and Reclaiming Processes at the CO2 Technology Centre Mongstad

In 2015, the CO2 Technology Center Mongstad (TCM DA), operated a test campaign using aqueous monoethanolamine (MEA) solvent at 30 wt%. The main objective was to demonstrate and document the performance of the TCM DA Amine Plant located in Mongstad, Norway. As part of the test campaign, thermal reclaiming was performed in order to eliminate accumulated degradation products and improve the solvent performance. This paper presents results and discussions concerning formation and monitoring of amine degradation products along with experiences related to the thermal reclaiming process and its operational procedure. Evaluations of the efficiency of thermal reclaiming and the solvent improvement after reclaiming are also presented. Published by Elsevier Ltd.

Topological virtual screening: A way to find new anticonvulsant drugs from chemical diversity

A topological virtual screening (tvs) test is presented, which is capable of identifying new drug leaders with anticonvulsant activity. Molecular structures of both anticonvulsant-active and non active compounds, extracted from the Merck Index database, were represented using topological indexes. By means of the application of a linear discriminant analysis to both sets of structures, a topological anticonvulsant model (tam) was obtained, which defines a connectivity function. On the basis of this model, 41 new structures with anticonvulsant activity have been identified by a topological virtual screening.
