Synthesis and biological activity of enantiomeric pairs of 5-[(E)-cycloalk-2-enylidenemethyl]thiolactomycin congeners

The title congeners were synthesized by employing our efficient synthetic route previously explored for preparing enantiomeric pairs of thiolactomycin and its 3-demethyl derivative. While all the synthesized congeners lacked in vitro antibacterial activity, some of the congeners bearing an (E)-cyclohept-2-enylidenemethyl or an (E)-cyclooct-2-enylidenemethyl group were found to exhibit more potent type I FAS inhibitory activity than (S)-3-demethylthiolactomycin having an unnatural configuration.

Effects of NOx in the flue gas degradation of MEA

Post combustion CO2 capture using amine absorbents is the most mature process and therefore the most relevant choice for realising full-scale capture within the next few years. The health and environmental impact of emissions to air is, however, a potential risk. Amines may react in the process or in the atmosphere post emission to form new substances that may be more harmful than the parent amine itself. The main objective of the current work was to investigate the flue gas degradation of monoethanolamine (MEA) in the process with special emphasis on the NOx induced chemical reactions. Degradation experiments have been carried out at absorber like conditions in the Aminox rig, followed by further degradation of the used solvent at higher temperature in a lab scale autoclave. Liquid samples were analysed by a range of methods to identify the formation of degradation by-products, with special focus on potential harmful compounds like nitrosamines and nitramines. On-line FT-IR and MS instruments were used for qualitative detection of volatile degradation products and to measure amine slip. MEA is a primary amine which in itself is unable to form a stable nitrosamine. However, experiments show that under the influence of NOx, MEA degrades to the secondary amine diethanolamine (DEA) which is then nitrosated. This work shows that some nitrosamine formation in the process must be expected from any amine. Based on data from real emission measurements, health and environmental risk assessment should be investigated in further studies.

N-thiolated 2-oxazolidinones: A new family of antibacterial agents for methicillin-resistant Staphylococcus aureus and Bacillus anthracis

In this report, we describe a new family of N-thiolated 2-oxazolidinones having antibacterial activity against methicillin-resistant Staphylococcus aureus and Bacillus anthracis. The effect of ring substituents and stereochemistry on antibacterial activity of these oxazolidinones closely parallels that previously reported for N-thiolated beta-lactam antibiotics.

Bismuth-catalyzed direct substitution of the hydroxy group in alcohols with sulfonamides, carbamates, and carboxamides

(Figure Presented) No preactivation of the alcohol substrates is required in allylic, propargylic, and benzylic aminations catalyzed by a combination of commercially available Bi(OTf)3 and KPF6, mostly at room temperature (see scheme). The substitution reactions of readily accessible allylic, propargylic, and benzylic alcohols with sulfonamides, carbamates, and carboxamides give the desired amine products in up to 99% yield.

Racemic auxiliaries: Applications to asymmetric synthesis

Racemic auxiliaries have been successfully used to achieve asymmetric synthesis. Racemic Evans aldol products were obtained from racemic acyl oxazolidinones with good diastereocontrol. The enantiomers of the racemic aldol products were resolved by a lipase-catalysed acylation reaction. Hydrolysis afforded enantiomerically enriched oxazolidinones and enantiomerically enriched beta-hydroxy acids.

The alpha-effect in cyclic secondary amines: new scaffolds for iminium ion accelerated transformations

Five-membered secondary amine heterocycles containing an alpha-heteroatom were prepared and shown to be ineffective as catalysts for the iminium ion catalysed Diels-Alder reaction between cinnamaldehyde and cyclopentadiene. Their six-membered counterparts proved to be highly active catalysts. In stark contrast, the catalytic activity observed when comparing the non alpha-heteroatom cyclic amines proline methyl ester and methyl pipecolinate showed the five-membered ring amine was significantly more active. Concurrent density functional theoretical calculations suggest a rationale for the observed trends in reactivity, highlighting that LUMO activation through an iminium ion intermediate plays a key role in catalytic activity.

Fenfluramine hydrochloride for the treatment of Dravet syndrome

Introduction: Fenfluramine (3?trifluoromethyl?N?ethylamphetamine), a former anorectic agent, has been successfully repurposed for Dravet syndrome (DS). Area covered: A systematic review of data on fenfluramine in the treatment of patients with DS has been conducted, with 11 published papers on the use of fenfluramine for DS (six clinical trials, of which two were randomized controlled trials (RCTs), and five preclinical studies). Following clinical observations suggesting the efficacy of fenfluramine, the effect on convulsive seizures has been confirmed by two RCTs. The first RCT demonstrated the efficacy of the two tested doses of 0.2 mg/kg/day and 0.7 mg/kg/day, while the second RCT showed the efficacy of 0.4 mg/kg/day fenfluramine in patients with DS treated with stiripentol. Expert opinion: Preclinical studies provide insights into the mechanisms of action of fenfluramine. There are still no large real-life studies. Fenfluramine is under investigation for the treatment of other epilepsy syndromes.
