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.

PEGylated polyplex micelles from triblock catiomers with spatially ordered layering of condensed pDNA and buffering units for enhanced intracellular gene delivery

An A-B-C type triblock copolymer, tandemly aligning two types of polycations with different pKa values in a single polymer strand, was developed for the construction of novel polyplex micelles, satisfying a high DNA condensing ability as well as a proton buffering activity directed to elevating gene transfection. The micelle might feature the distinctive three-layered structure, where an inner polyplex layer of condensed pDNA with poly(l-lysine) (pKa ?9.4) as the C segment is successively wrapped with an intermediate layer of poly[(3-morpholinopropyl)aspartamide] (B segment) with a comparatively low pKa of?6.2, to provide a buffering effect, and an outer PEG layer (A segment) as a biocompatible palisade.
