2-Position-selective C-H fluoromethylation of six-membered heteroaryl N-oxides with (fluoromethyl)triphenylphosphonium iodide

A mild and efficient method for the regioselective C-H fluoromethylation of heteroaryl N-oxides with (fluoromethyl)triphenylphosphonium iodide is presented. With LiOt-Bu as the base and HMSO as the solvent, this reaction delivers a series of C2-fluommethylated pyridine and quinoline derivatives in moderate to good yields. This protocol also extends the synthetic applications of (fluommethyl)triphenylphosphonium iodide.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 90-52-8, in my other articles.

Chronic but not acute pharmacological activation of SERCA induces behavioral and neurochemical effects in male and female mice

Intracellular calcium (Ca2+) homeostasis is a vital process to nerve cell survival and function with an intricate regulatory network. It is well established that the endoplasmic reticulum (ER) is a major intraneuronal Ca2+ storage and that the sarco/endoplasmic reticulum (SR/ER) calcium (Ca2+)-ATPase (SERCA) pump is a key regulator of cytosolic Ca2+ levels. SERCA pumps play a critical role in brain pathophysiology, thus SERCA comprises an emerging pharmacological target for the treatment of brain diseases. Interestingly, preclinical studies in rodents suggest that chronic pharmacological activation of SERCA2 by the quinoline derivative CDN1163 comprises a potential pharmacotherapeutic target in Alzheimer’s and Parkinson’s diseases. As little is known about the behavioral and neurochemical consequences of CDN1163 administration, in the current study we investigated the potential effects of acute (i.e., at 1 h) and chronic (i.e., 17 days) CDN1163 administration (i. e., 10 mg/kg and 20 mg/kg; intraperitoneally) on locomotor activity and relevant affective behaviors, as well as on monoaminergic neurotransmission in naive C57BL/6J mice of both sexes. Interestingly, chronic, but not acute, CDN1163 administration induced anxiogenic and depressive-like behavioral effects in mice, as assessed in the open field (OF) test and the forced swim test (FST), respectively. In addition, chronic CDN1163 administration induced sustained sexand brain region-dependent noradrenergic and serotonergic neurochemical effects ex vivo. Taken together, present findings support the critical role of SERCA-dependent Ca2+ handling in regulating behavior and neurochemical activity, and further highlight the need to consider sex in the development of SERCA-targeting pharmacotherapies for the treatment of debilitating brain disorders.

Single-Pot Synthesis of NiMo-Al2O3 Catalyst for Quinoline Hydrodenitrogenation

Mesoporous NiMo-Al2O3 catalysts were synthesized without the structure-directing agent by a single-pot method and were studied for quinoline hydrodenitrogenation (HDN). These catalysts were characterized by N-2 physisorption, X-ray diffraction (XRD), temperature-programmed reduction by hydrogen (H-2-TPR), and UV-vis/diffuse reflection spectroscopy (UV-vis DRS). The Mo sulfidation and morphology structures of (Ni)MoS2 crystallites of sulfided catalysts were analyzed by X-ray photoelectron spectroscopy (XPS) and high-resolution transmission electron microscopy (HRTEM). The NiMo catalysts with different textural properties and metal-support interaction could be controlled by adjusting the hydrolysis process. The catalyst prepared with direct hydrolysis (the NM-dh sample) exhibited the best catalytic performance, with quinoline conversion of 96.9% and the DN products selectivity of 60.5%. The catalytic results highlighted the effect of the metal-support interaction on HDN performance. The incorporation of citric acid as a chelate additive resulted in a decrease in catalytic activity and selectivity, providing evidence that the catalytic HDN performance was very selective to the agglomeration of Mo species.

Catalytic Asymmetric Aza-Diels-Alder Reaction: Pivotal Milestones and Recent Applications to Synthesis of Nitrogen-Containing Heterocycles

In this review, the pivotal achievements and recent advances in catalytic asymmetric aza-DAR reported up to 2020 are retrospectively considered and their potency for enantioselective synthesis of useful chiral piperidine, quinoline, pyridazine, oxazine and oxadiazine derivatives and fused compounds of higher molecular complexity bearing these pharmacology-relevant heterocyclic scaffolds is demonstrated. The reported data are systematized according both to key electron transfer modes (normal or invers electron demand reactions) and to main types of attainable heterocyclic products. Of significant attention are an analysis of activation strategies (complexation, enamine or enolate formation, H-bonding, etc.) applicable to reactions with particular types of dienes and dienophiles and identification of plausible reaction pathways (either concerted or stepwise) over stereoselective cyclization processes. The review contains 310 references and 122 synthetic schemes.

Recent Advances in the Development of Broad-Spectrum Antiprotozoal Agents

Infections caused by Trypanosoma brucei, Trypanosoma cruzi, Leishmania spp., Entamoeba histolytica, Giardia lamblia, Plasmodium spp., and Trichomonas vaginalis, are part of a large list of human parasitic diseases. Together, they cause more than 500 million infections per year. These protozoa parasites affect both low- and high-income countries and their pharmacological treatments are limited. Therefore, new and more effective drugs in preclinical development could improve overall therapy for parasitic infections even when their mechanisms of action are unknown. In this review, a number of heterocyclic compounds (diamidine, guanidine, quinoline, benzimidazole, thiazole, diazanaphthalene, and their derivatives) reported as antiprotozoal agents are discussed as options for developing new pharmacological treatments for parasitic diseases.

Synthesis of Quinoline-4-carboxamides and Quinoline-4-carboxylates via a Modified Pfitzinger Reaction of N-Vinylisatins

A synthetic approach for the accelerated assembly of quinoline-4-carboxamide and quinoline-4-carboxylate nuclei is presented. The methodology is based on the rearrangement of N-vinylisatins promoted by different types of amines (or ethanol) in a Pfitzinger-type mechanism that, in turn, builds the quinoline ring system. The reaction took place only by heating the starting materials in ethanol, without any additive.

Diversification of quinoline-triazole scaffolds with CORMs: Synthesis, in vitro and in silico biological evaluation against Plasmodium falciparum

A discrete series of tricarbonyl manganese and rhenium complexes conjugated to a quinoline-triazole hybrid scaffold were synthesised and their inhibitory activities evaluated against Plasmodium falciparum. In general, the complexes show moderate activity with improved inhibitory activities for the photoactivatable manganese(I) tricarbonyl complexes in the malaria parasite. All complexes are active in the dark against the NF54 CQS (chloroquine-sensitive) and K1 MDR (multidrug-resistant) strains of Plasmodium falciparum, with IC50 values in the low micromolar range. Of significance, the complexes retain their activity in the MDR strain with resistance indices ranging between 1.1 and 2.1. The Mn(I) analogues display photodissociation of all three CO ligands upon irradiation at 365 nm. More importantly, the complexes show increased antimalarial activity in vitro upon photoactivation, something not observed by the clinically used reference drug, chloroquine. As a purported mechanism of action, the compounds were evaluated as beta-haematin inhibitors. To further understand the interactions of the complexes, in silico hemozoin docking simulations were performed, attesting to the fact that CO-release could be vital for blocking the hemozoin formation pathway. These results show that this strategy may be a valuable, novel route to design antimalarial agents with higher efficacy.

A novel chemosensor for the distinguishable detections of Cu2+ and Hg2+ by off-on fluorescence and ratiometric UV-visible absorption

A novel dual-functional chemosensor, derived from the conjugation of rhodamine B with a quinoline derivative (RHQ), was firstly synthesized with high efficiency and cost-effectiveness for the distinguishable detections of Cu2+ and Hg2+ via ring-opening and ring-forming mechanism. The chemosensor exhibits highly selective and distinguishable responses for Cu2+ and Hg2+ in CH3CN-H2O (4:1, v/v) with off-on fluorescence and ratiometric ultraviolet-visible (UV-Vis) absorption changes. Additionally, Cu2+ is identified by opening a rhodamine spirocycle with a UV-Vis absorption band, at around 560 nm and fluorescence turn-on. Interestingly, Hg2+ is discerned by opening the rhodamine spirocycle and by generating a new special cycle for the quinoline unit. Resultantly, there were two UV-Vis absorption bands at around 365 nm and 560 nm, which were accompanied by fluorescence turn-on. Moreover, the chemosensor can quantitatively detect Cu2+ and Hg2+ by off-on fluorescence and ratiometric UV-Vis absorption changes, respectively. Furthermore, the chemosensor with low cytotoxicity could be successfully administered to monitor Cu2+ and Hg2+ in living cells. This work may pay the way for the development of dualfunctional chemosensor for quantificationally detecting metal ions in environmental and biological systems. (C) 2020 Elsevier B.V.

A purine based fluorescent chemosensor for the selective and sole detection of Al3+ and its practical applications in test strips and bio-imaging

A novel purine Schiff base fluorescent probe (WYW), (E)-4-methyl-2-((2-(9-(naphthalen-1-yl)-8-(thiophen-2-yl)-9H-purin-6-yl)hydrazono)methyl)phenol, was designed and prepared as an excellent reversible fluorescent chemosensor for monitoring Al3+. The fluorogenic turn-on sensor WYW exhibited high selectivity towards Al3+ over other coexistent metal ions, accompanying with an obvious visual color change in DMSO/H2O (9/1, v/v, pH = 7.4) media. The enhancement fluorescence of WYW could be attributed to the inhibition of PET and ESIPT process induced by Al3+. Notably, theWYW-Al3+ complex exhibited a fluorescence turn-off response towards F- with exceptional selectivity via the displacement approach. The detection limit of WYWfor Al3+ was calculated to be as low as 82 nM. The formation of complex WYW-Al3+ (1:1 stoichiometry) was confirmed by Job’s methods and further verified by density functional theory (DFT) calculations. Furthermore, the probe WYW with low cytotoxicity and excellent membrane-permeable property has also been successfully applied for detecting low concertation Al3+ in living HeLa cells.
