The cascade amination/cyclization ofN-arylacrylamides with alkyl amines under visible-light photoredox catalysis is realized via intermediacy of aminium radicals. The aminium radicals are generated by a two-step sequence which involves N-chlorination of alkyl amines and subsequent reductive N-Cl cleavage. This method provides a convenient access to aminated oxindoles.

The N/N donor-type bromobenzyldiamines (1-3) were successively prepared by reduction of Schiff bases formed as a result of condensation reactions of 4-bromobenzaldehyde with aliphatic diamines. The Cl exchange reactions of hexachlorocyclotriphosphazene (HCCP; trimer; N3P3Cl6; 4) with the bidentate ligands (1-3) produced the new monospiro- (5-7) and dispirocyclotriphosphazenes (8-13) containing 4-bromo-benzyl pendant arm(s). The tetrachloro phosphazenes (5-7) were reacted with pyrrolidine, tetra-1,4-dioxa-8-azaspiro [4.5]decane (DASD) and piperidine to give the tetraamino substituted mono-spirophosphazenes (5a-7c). The spectral analyses of all the phosphazenes were made using appropriate spectroscopic methods; such as FTIR, H-1, C-13, P-31 NMR and ESI-MS. The molecular and crystal structures of 5, 6, 7 and 12 were also determined by X-ray crystallography. On the other hand, the antimicrobial activities of the phosphazenes were evaluated against G (-) and G (+) bacteria and fungi. Some of the tetraaminophosphazenes were found to be very active against several bacteria and fungi. Besides, the interactions of the cyclotriphosphazenes with plasmid DNA were investigated using agarose gel electrophoresis. (C) 2020 Elsevier B.V. All rights reserved.

Aberrant activation of FMS-like tyrosine receptor kinase 3 (FLT3) is implicated in the pathogenesis of acute myeloid leukemia (AML) in 20-30% of patients. In this study we identified a highly selective (phenylethenyl)quinazoline compound family as novel potent inhibitors of the FLT3-ITD and FLT3-D835Y kinases. Their prominent effects were confirmed by biochemical and cellular proliferation assays followed by mice xenograft studies. Our modelling experiments and the chemical structures of the compounds predict the possibility of covalent inhibition. The most effective compounds triggered apoptosis in FLT3-ITD AML cells but had either weak or no effect in FLT3-independent leukemic and non-leukemic cell lines. Our results strongly suggest that our compounds may become therapeutics in relapsing and refractory AML disease harboring various ITD and tyrosine kinase domain mutations, by their ability to overcome drug resistance.

Introduction Pressure support ventilation (PSV) should allow spontaneous breathing with a normal neuro-ventilatory drive. Low neuro-ventilatory drive puts the patient at risk of diaphragmatic atrophy while high neuro-ventilatory drive may causes dyspnea and patient self-inflicted lung injury. We continuously assessed for 12 h the electrical activity of the diaphragm (EAdi), a close surrogate of neuro-ventilatory drive, during PSV. Our aim was to document the EAdi trend and the occurrence of periods of Low and/or High neuro-ventilatory drive during clinical application of PSV. Method In 16 critically ill patients ventilated in the PSV mode for clinical reasons, inspiratory peak EAdi peak (EAdi(PEAK)), pressure time product of the trans-diaphragmatic pressure per breath and per minute (PTPDI/b and PTPDI/min, respectively), breathing pattern and major asynchronies were continuously monitored for 12 h (from 8 a.m. to 8 p.m.). We identified breaths with Normal (EAdi(PEAK) 5-15 mu V), Low (EAdi(PEAK) < 5 mu V) and High (EAdi(PEAK) > 15 mu V) neuro-ventilatory drive. Results Within all the analyzed breaths (177.117), the neuro-ventilatory drive, as expressed by the EAdi(PEAK), was Low in 50.116 breath (28%), Normal in 88.419 breaths (50%) and High in 38.582 breaths (22%). The average times spent in Low, Normal and High class were 1.37, 3.67 and 0.55 h, respectively (p < 0.0001), with wide variations among patients. Eleven patients remained in the Low neuro-ventilatory drive class for more than 1 h, median 6.1 [3.9-8.5] h and 6 in the High neuro-ventilatory drive class, median 3.4 [2.2-7.8] h. The asynchrony index was significantly higher in the Low neuro-ventilatory class, mainly because of a higher number of missed efforts. Conclusions We observed wide variations in EAdi amplitude and unevenly distributed Low and High neuro ventilatory drive periods during 12 h of PSV in critically ill patients. Further studies are needed to assess the possible clinical implications of our physiological findings. Category: piperidines.

kappa opioid receptor (KOR) antagonists are potential pharmacotherapies for the treatment of migraine and stress-related mood disorders including depression, anxiety, and drug abuse, thus the development of novel KOR antagonists with an improved potency/selectivity profile and medication-like duration of action has attracted the interest of the medicinal chemistry community. In this paper, we describe the discovery of 1-(6-ethyl-8-fluoro-4-methyl-3-(3-methyl-1,2,4-oxadiazol-5-yl)quinolin-2-yl)-N-(tetrahydro-2 H-pyran-4-yl)piperidin-4 amine (CYM-53093, BTRX-335140) as a potent and selective KOR antagonist, endowed with favorable in vitro ADMET and in vivo pharmacokinetic profiles and medication-like duration of action in rat pharmacodynamic experiments. Orally administered CYM-53093 showed robust efficacy in antagonizing KOR agonist-induced prolactin secretion and in tail-flick analgesia in mice. CYM-53093 exhibited a broad selectivity over a panel of off-target proteins. This compound is in phase 1 clinical trials for the treatment of neuropsychiatric disorders wherein dynorphin is thought to contribute to the underlying pathophysiology.

Oxidative carbonylation using CO/O-2 is an attractive strategy to construct carbonyl compounds, but the explosive limit of the gas mixture hampers its application. Now, this safety issue is overcome in the aminocarbonylation of alkynes by replacing the external oxidant O-2 by electrochemistry facilitating a mild and safe reaction. Palladium-catalysed oxidative carbonylation using oxygen as the oxidant is an economical approach; however, the gas mixture of CO and air has an explosive limit of 12.5-74.0% that could hamper extensive application of this process. Herein we report an electrochemical aminocarbonylation of alkynes under atmospheric pressure in an undivided cell without an external oxidant. The transformation has a broad substrate scope (83 examples) that involves primary amines and ammonium salts. Furthermore, mechanistic studies through cyclic voltammetry, in situ infrared and quick-scanning X-ray absorption fine structure spectroscopy reveal the reasons for this protocol proceeding smoothly under electrochemical conditions.

Direct reductive N-alkylation of secondary amines with carboxylic acids using molybdenum hexacarbonyl (5 mol %) as catalyst and diethoxymethylsilane as reducing agent generate enamines in a straightforward fashion in high yields. The formed enamines are without the need for isolation or purification further reacted with trimethylsilyl cyanide in the same reaction flask to yield alpha-amino nitriles in good yields. In the optimized reaction conditions equimolar amounts of carboxylic acid and amine are reacted under neat conditions, and a catalytic amount of trifluoroethanol (0.1 mol %) is added along with TMSCN for the cyanation step. The reductive N-alkylation reaction is demonstrated to be highly chemoselective, tolerating a multitude of different functional groups present in the starting carboxylic acids and amines. The reaction is scalable and the generated alpha-amino nitriles are converted to other useful compounds, e.g., alpha-amino acids or amino-tetrazoles. In addition, the intermediate enamines are further transformed into triazolines, sulfonylformamidines, pyrimidinediones, and TMS-propargylamines, respectively, in high yields under mild reaction conditions. Benzoic acids react with secondary amines under similar conditions to give tertiary amines in high yields, and using this methodology, the biologically active compound Piribedil was isolated in 80% yield in a direct one-pot reaction setup.
