N-heterocyclic olefins as dative carbon donor ligands for diaminoplumbylenes: Syntheses and crystal structures of adducts with 1,3,4,5-tetramethyl-2-methyleneimidazoline

The aim of this study was to shed more light on the potential of N-heterocyclic olefins as carbon donor ligands for the coordination/stabilization of divalent Group 14 element compounds. Stable adducts of the N-heterocyclic olefin 1,3,4,5-tetramethyl-2-methyleneimidazoline (MeIMeCH2) were isolated with the cyclic diaminoplumbylenes ph(NSiMe3)(2)Pb (ph = 1,2-phenylene) and fc(NSiRMe2)(2)Pb (fc = 1,10-ferrocenylene; R = Me, tBu) as well as with the acyclic congener [(Me3Si)(2)N](2)Pb. In contrast, the cyclic (alkyl)(amino)carbene 1-(2,6-diisopropylphenyl)-3,3-diethyl-5,5-dimethylpyrrolidin-2-ylidene (CAAC(Et)) gave rise to a stable adduct only with ph(NSiMe3)(2)Pb. The ferrocene-based N-heterocyclic olefin fc (NCH(2)tBu)(2)CCH2 was synthesised. It afforded a stable adduct with triphenylborane, but not with the diaminoplumbylenes of this study. All stable adducts were structurally characterized by single-crystal X-ray diffraction. An essentially perpendicular orientation of the Pb-C bond vector with respect to the PbN2 plane was found for the diaminoplumbylene adducts. Pb-207 NMR spectroscopic data suggest, but do not prove, that the strength of the donor-acceptor interaction of the (IMeCH2)-I-Me adducts is lower than that of adducts with the related N-heterocyclic carbene 1,3,4,5-tetramethylimidazolin-2-ylidene, but higher than that of adducts with the popular N-donor 4-(dimethylamino)pyridine.

mGluR5 Allosteric Modulation Promotes Neurorecovery in a 6-OHDA-Toxicant Model of Parkinson’s Disease

Parkinson’s disease is a neurodegenerative disease characterized by a loss of dopaminergic substantia nigra neurons and depletion of dopamine. To date, current therapeutic approaches focus on managing motor symptoms and trying to slow neurodegeneration, with minimal capacity to promote neurorecovery. mGluR5 plays a key role in neuroplasticity, and altered mGluR5 signaling contributes to synucleinopathy and dyskinesia in patients with Parkinson’s disease. Here, we tested whether the mGluR5-negative allosteric modulator, (2-chloro-4-[2[2,5-dimethyl-1-[4-(trifluoromethoxy) phenyl] imidazol-4-yl] ethynyl] pyridine (CTEP), would be effective in improving motor deficits and promoting neural recovery in a 6-hydroxydopamine (6-OHDA) mouse model. Lesions were induced by 6-ODHA striatal infusion, and 30 days later treatment with CTEP (2 mg/kg) or vehicle commenced for either 1 or 12 weeks. Animals were subjected to behavioral, pathological, and molecular analyses. We also assessed how long the effects of CTEP persisted, and finally, using rapamycin, determined the role of the mTOR pathway. CTEP treatment induced a duration-dependent improvement in apomorphine-induced rotation and performance on rotarod in lesioned mice. Moreover, CTEP promoted a recovery of striatal tyrosine hydroxylase-positive fibers and normalized FosB levels in lesioned mice. The beneficial effects of CTEP were paralleled by an activation of mammalian target of rapamycin (mTOR) pathway and elevated brain-derived neurotrophic factor levels in the striatum of lesioned mice. The mTOR inhibitor, rapamycin (sirolimus), abolished CTEP-induced neurorecovery and rescue of motor deficits. Our findings indicate that mTOR pathway is a useful target to promote recovery and that mGluR5 allosteric regulators may potentially be repurposed to selectively target this pathway to enhance neuroplasticity in patients with Parkinson’s disease.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 503615-03-0, you can contact me at any time and look forward to more communication. COA of Formula: C15H17N3O4.

Stable and Bright Pyridine Manganese Halides for Efficient White Light-Emitting Diodes

Highly efficient lead halide perovskites with tunable emission performance have become new candidate materials for light-emitting devices and displays; however, the toxicity of lead and instability of halide perovskites greatly limits their application. Herein, rapid and large-scale synthesis of highly emissive organic-inorganic manganese halide perovskites, (C5H6N)(2)MnBr4 and C5H6NMnCl3, are presented by a one-pot solution-based method, of which (C5H6N)(2)MnBr4 displays a high absolute photoluminescence quantum yield (95%) in the solid-state. The developed (C5H6N)(2)MnBr4 perovskite noticeably exhibits high stability. Therefore both as-synthesized green and red emissive manganese-based phosphors with superior optical properties are used to fabricate blue light pumped white light-emitting diodes (WLEDs), displaying excellent quality white light with a high color rendering index value of 91 and a correlated color temperature of 5331 K. This study not only presents the robust large-scale production synthetic approach for organic-inorganic manganese halide perovskites, but also facilitates the development of high-performance phosphors for future lighting and display technologies.

Update on novel purinergic P2X3 and P2X2/3 receptor antagonists and their potential therapeutic applications

Introduction: Purinergic P2X3-P2X2/3 receptors are placed in nociceptive neurons’ strategic location and show unique desensitization properties; hence, they represent an attractive target for many pain-related diseases. Therefore, a broad interest from academic and pharmaceutical scientists has focused on the search for P2X3 and P2X2/3 receptor ligands and has led to the discovery of numerous new selective antagonists. Some of them have been studied in clinical trials for the treatment of pathological conditions such as bladder disorders, gastrointestinal and chronic obstructive pulmonary diseases. Areas covered: This review provides a summary of the patents concerning the discovery of P2X3 and/or P2X2/3 receptor antagonists published between 2015 and 2019 and their potential clinical use. Thus, the structures and biological data of the most representative molecules are reported. Expert opinion: The 2016 publication of the crystallographic structure of the human P2X3 receptor subtype gave an improvement of published patents in 2017. Hence, a great number of small molecules with dual antagonist activity on P2X3-P2X2/3 receptors, a favorable pharmacokinetic profile, and reasonable oral bioavailability was discovered. The most promising compounds are the phenoxy-diaminopyrimidines including gefapixant (AF-219), and the imidazo-pyridines like BLU-5937, which are in phase III and phase II clinical trials, respectively, for refractory chronic cough.

Hierarchically Porous Mixed Oxide Sheetlike Copper-Aluminum Nanocatalyzed Synthesis of 2-Alkynyl Pyrrolidines/Piperidines and Their Ideal Green Chemistry Metrics

Design and development of selective and efficient catalysts involving abundantly available transition metal-based nanoparticles for multicomponent reaction in industry and academia have gained much attention in recent years. An efficient catalytic process not only reduces the manufacturing cost but also minimizes the waste disposal. Herein, we report the application of facile fabricated reusable calcinated copper-aluminum mixed oxide nanocomposites (CuAl-MO NCs) for highly efficient and selective one-pot green synthesis of substituted pyrrolidines/piperidines via KA(2) coupling reaction of a ketone, amine, and alkyne. The prepared material was well-characterized by HR-XRD, SEM, HR-TEM, EDX, ICP-OES/MS, BET, and XPS analyses, revealing highly dispersed porous sheetlike CuAL-MO NCs. The prepared CuAl-MO nanomaterial substantially boosted the catalytic efficiency by demonstrating high stability and easy retrievability of catalyst for successive reuses without significant loss in both activity and selectivity. The present methodology is facile, follows green principles, and showed ideal values of green chemistry metrics such as high atom economy (AE), reaction mass efficiency (RME), low E-factor, carbon efficiency (CE), and process mass intensity (PMI).

Investigation of nicotinamide and isonicotinamide derivatives: A quantitative and qualitative structural analysis

An anhydrous nature of benzylidene derivatives of nicotin and isonicotinamides crystal structures is determined and studied for their weak intermolecular interactions. The molecular structure is nonplanar in general with the pyridine ring twisted with respect to the central hydrazone moiety. The crystal structures depict various intermolecular interactions, including N-H center dot center dot center dot O, C-H center dot center dot center dot O, N-H center dot center dot center dot N, and C-H center dot center dot center dot N hydrogen bonding along with weak C-H center dot center dot center dot pi and pi center dot center dot center dot pi contacts. Further, Hirshfeld surface and 2D-fingerprint plot analysis confirm the role of intermolecular interactions in building the crystal packing in these derivatives. The PIXELC energy calculation shows that dispersion energy plays an essential role in stabilizing the crystal packing in all six derivatives. (C) 2019 Elsevier B.V. All rights reserved.

Synthesis and characterization of tridentate phosphine ligands incorporating long methylene chains and ethoxysilane groups for immobilizing molecular rhodium catalysts

The new tridentate phosphine ligands EtOSi((CH2)(n)PPh2)(3) and O[Si((CH2)(n)PPh2)(3)](2) (n = 4, 7, 11), as well as their precursor ethoxysilanes EtOSi((CH2)(m)CH = CH2)(3) and disiloxanes O[Si((CH2)(m)CH = CH2)(3)](2) (m = 2, 5, 9) and EtOSi(CH2)(11)PPh2RhClCOD)(3) (COD = cyclooctadiene) have been synthesized and fully characterized. The ethoxysilane- and disiloxane-containing phosphine ligands have been immobilized on silica via covalent siloxane bonds. The immobilized linkers have been characterized by P-31 and Si-29 CP/MAS and HRMAS NMR spectroscopy. The covalent siloxane bonds between the linkers and the silica surface prevent translational mobility of the phosphines. Immobilized Wilkinson-type Rh hydrogenation catalysts have been obtained by ligand exchange of ClRh(PPh3)(3) and ClRhpyCOD (py = pyridine) with the surface-bound ligands. The single crystal X-ray structure of ClRhpyCOD has been reported. The activities and lifetimes have been studied for the hydrogenation of 1-dodecene. The new catalysts are highly active and they can be recycled up to 15 times without major loss of activity. Within the first hours of the catalytic reaction the initially molecular complexes form Rh nanoparticles with a narrow size ‘distribution on the surface. The nanoparticles do not leach into the supernatant solution and are not air-sensitive.
