The characteristics and mechanism of NO formation during pyridine oxidation in O-2/N-2 and O-2/CO2 atmospheres

The characteristics and mechanism of NO formation during pyridine oxidation in O-2/CO2 atmospheres are investigated both experimentally and numerically. Comparison experiments in O-2/N-2 and O-2/CO2 atmospheres are performed in a flow reactor at atmospheric pressure covering fuel-rich to fuel-lean equivalence ratios with temperature ranging from 773 K to 1573 K. Experimental results indicated that HCN is completely consumed in CO2 atmospheres, whereas significant amounts remain in N-2 atmospheres under fuel-rich conditions. Compared with O-2/N-2 atmospheres, the formation of NO in O-2/CO2 atmospheres is reduced by 8.85% and 5.8% under stoichiometric and fuel-lean conditions respectively, whereas it is 5.15% greater under fuel-rich conditions. A newly developed chemical kinetic mechanism based on our previous studies satisfactorily reproduced the main features of CO, HCN, and NO formation. The conversion differences of pyridine to NO between O-2/CO2 and O-2/N-2 atmospheres are mainly due to the differences of conversion of HCN to NO. The conversion ratio discrepancies of pyridine to HCN are all less than 2%. The conversion ratios of HCN to NO in O-2/N-2 and O-2/CO2 atmospheres are 7.2% and 15.6% under fuel-rich conditions, 65.3% and 57.4% under stoichiometric conditions, and 83.5% and 76.3% under fuel-lean conditions, respectively.

Cu-Mediated Amination of (Hetero)Aryl C-H bonds with NH Azaheterocycles

Direct synthesis of N-(hetero)arylated heteroarenes has been realized through Cu-mediated C-N coupling of NH azaheterocycles with aryl C-H bonds under aerobic conditions. This method features a broad scope of both heterocyclic arenes (pyridine, quinoline, pyrazole, imidazole, furan, thiophene, benzofuran, and indole) and NH azaheterocycles (imidazole, pyrazole, indole, azindole, purine, indazole, benzimidazole, pyridone, carbazole), providing a versatile method for the synthesis of pharmaceutically important N-(hetero)arylated heteroarenes. The versatility of this reaction was further demonstrated through late-stage modification of marketed drugs and the synthesis of a key intermediate for accessing a class of angiotensin II receptor 1 antagonists.

Flow hydrodynamics in a gas-solid fluidized bed reactor with two reaction zones

A novel reactor with two reaction zones is proposed for pyridine synthesis. The flow hydrodynamics were investigated in experiments. Pressure taps and a PV-6D optical fiber were used to measure the pressure fluctuation and particle concentration, respectively. Hilbert-Huang analysis was adopted to distinguish the flow patterns through pressure fluctuation. Results show that the flow patterns are bubbling fluidization and fast fluidization in the regions below (reaction zone I) and above (reaction zone II) the nozzles, respectively. The radial distribution of the cluster time fraction was obtained through signal waves of the particle concentration. Analysis of the cluster time fraction revealed two radial distributions. In the region around the nozzles, the cluster time fraction ranged from 0 to 0.2 and concentrated at radial positions r/R= 0-1, which resulted from unsymmetrical catalyst feeding. In reaction zone II, the cluster time fraction ranged from 0 to 0.2, and the radial distribution indicated a core-annulus structure.

Template-Free Synthesis of a Macrocyclic Bis(pyridine-dienamine) Proligand and Metal Complexes of Its Bis(pyridine-diimine) and Bis(pyridine-dienamido) Forms

We describe the template-free synthesis of the bis(pyridine-dienamine) proligand [4,5-(m-xylylenediamine)NH-C=(CH)(9-butyl-octahydroacridine)] 2 (2′), a variant of Burrows’s macrocyclic bis(pyridine-diimine) (bis-PDI) ligand [2,6-(m-xylylenediamine)N=C(py)](2) (A), using octahydroacridine as the ligand backbone. The octahydroacridine backbone favors macrocyclization by constraining the PDI units in the (s-cis)(2) conformation. The template-free synthesis of 2′ enables facile access to a wide array of bis-PDI and bis(pyridine-dienamido) (bis-PDE) metal complexes. Five-coordinate binuclear bis-PDI (2)M2Cl4 complexes {2 = [4,5-(m-xylylenediamine)-N=C(9-butyl-octahydroacridine)](2); M = Zn, Co, or Fe} and a four-coordinate bis-PDI [(2)Pd2Br2][B(3,5-(CF3)(2)-Ph)(4)](2) complex were synthesized and characterized. (2)Zn2Cl4 undergoes macrocyclic ring inversion on the nuclear magnetic resonance (NMR) time scale with a free energy barrier Delta G(double dagger) of 15.5(3) kcal/mol at 295 K. In contrast, (2)Fe2Cl4 and (2)Co2Cl4 undergo slow ring inversion on the NMR chemical shift time scale at 295 K. The amine elimination reaction of 2′ with Zr(NMe2)(4) yields the bis-PDE complex (2′-4H)Zr-2 (NMe2)(4), which was alkylated with AlMe3 and Al(CH2SiMe3)(3) to generate (2′-4H)Zr2Me4 and (2′-4H)Zr-2(CH2SiMe3)(2)(NMe2)(2), respectively.

Non-Nucleoside Agonists of the Adenosine Receptors: An Overview

Potent and selective adenosine receptor (AR) agonists are of pharmacological interest for the treatment of a wide range of diseases and conditions. Among these derivatives, nucleoside-based agonists represent the great majority of molecules developed and reported to date. However, the limited availability of compounds selective for a specific AR subtype (i.e., A(2B)AR) and a generally long and complex synthetic route for largely substituted nucleosides are the main drawbacks of this category of molecules. Non-nucleoside agonists represent an alternative set of compounds able to stimulate the AR function and based on simplified structures. This review provides an updated overview on the structural classes of non-nucleoside AR agonists and their biological activities, with emphasis on the main derivatives reported in the literature. A focus is also given to the synthetic routes employed to develop these derivatives and on molecular modeling studies simulating their interaction with ARs.

Bromide ion-functionalized nanoprobes for sensitive and reliable pH measurement by surface-enhanced Raman spectroscopy

4-Mercaptopyridine (4-Mpy) is a pH reporter molecule commonly used to functionalize nanoprobes for surface-enhanced Raman spectroscopy (SERS) based pH measurements. However, nanoprobes functionalized by 4-Mpy alone have low pH sensitivity and are subject to interference by halide ions in sample media. To improve nanoprobe pH sensitivity and reliability, we functionalized gold nanoparticles (AuNPs) with both 4-Mpy and bromide ion (Br-). Br- electrostatically stabilizes protonated 4-Mpy, thus enabling sensitive SERS detection of the protonation state of 4-Mpy as a function of pH while also reducing variability caused by external halide ions. Through optimization of the functionalization parameters, including suspension pH, [4-Mpy], and [Br-], the developed nanoprobes enable monitoring of pH from 2.1 to 10 with high SERS activity and minimal interference from halide ions within the sample matrix. As a proof of concept, we were able to track nanoprobe location and image the pH distribution inside individual cancer cells. This study provides a novel way to engineer reliable 4-Mpy-functionalized SERS nanoprobes for the sensitive analysis of spatially localized pH features in halide ion-containing microenvironments.

Dynamic Open Coordination Cage from Nonsymmetrical Imidazole-Pyridine Ditopic Ligands for Turn-On/Off Anion Binding

This work demonstrates a new nonconventional ligand design, imidazole/pyridine-based nonsymmetrical ditopic ligands (1 and 1(S)), to construct a dynamic open coordination cage from nonsymmetrical building blocks. Upon complex formation with Pd2+ at a 1:4 molar ratio, 1 and 1(S) initially form mononuclear PdL4 complexes (Pd2+(1)(4) and Pd2+(1(S))(4)) without formation of a cage. The PdL4 complexes undergo a stoichiometrically controlled structural transition to Pd2L4 open cages ((Pd2+)(2)(1)(4) and (Pd2+)(2)(1(S))(4)) capable of anion binding, leading to turn-on anion binding. The structural transitions between the Pd2L4 open cage and the PdL4 complex are reversible. Thus, stoichiometric addition (2 equiv) of free 1(S) to the (Pd2+)(2)(1(S))(4) open cage holding a guest anion ((Pd2+)(2)(1(S))(4).G(-)) enables the structural transition to the Pd2+(1(S))(4) complex, which does not have a cage and thus causes the release of the guest anion (Pd2+(1(S))(4)+G(-)).

Ultrasound-Promoted Synthesis of Spirocyclopropanes from Switchable Starting Materials via Azomethine Ylide [3+2]-Cycloaddition

An ultrasound-promoted green protocol to access a new series of spirocyclopropanes from indeno[1,2-b]quinoxaline derivatives and azomethine ylides, generated in situ from the iodine-catalyzed reaction of acetophenones as well as of 2-methylquinoline with pyridine in the presence of a base, is described. These transformations proceed via a spirocyclopropanation reaction followed by elimination of pyridine. Clear evidence for the structure of a spirocyclopropane-linked indenoquinoxaline derivative was obtained from single-crystal X-ray analysis. The most important feature of this reaction is the fact it forms three stereogenic centers, one of which is quaternary, with excellent selectivity.

Lipid-soluble arsenic species identified in the brain of the marine fish skipjack tuna (Katsuwonus pelamis) using a sequential extraction and HPLC/mass spectrometry

Lipid-soluble arsenicals, so called arsenolipids, occur in appreciable quantities in various marine organisms including fish. In this study, arsenolipids as well water-soluble arsenic species were investigated in brain (9.1-17.4 mg As per kg; dry mass) and muscle (4.0-5.8 mg As per kg; dry mass) tissues in five specimens of the marine fish skipjack tuna (Katsuwonus pelamis). For this purpose, we developed a sequential extraction method whereby the freeze-dried tissue was first treated with pyridine (organic extract) followed by aqueous ammonium bicarbonate (water extract) to extract arsenolipids and water-soluble species, respectively. When the method was applied to the tuna tissues, the arsenic distribution for brain was 55% (organic extract), 30% (water extract) and 15% (pellet), whereas for muscle tissue the corresponding values were 20%, 55%, and 25%. Arsenic species in water and organic extracts of muscle and brain tissues were investigated by HPLC/mass spectrometry. For both tissues, the water extracts contained arsenobetaine as the major arsenic species together with small amounts of dimethylarsinate and trimethylarsine oxide; trace amounts of dimethylarsinoyl propionic acid were found only in brain tissues. Arsenic-containing hydrocarbons (AsHCs), were the major arsenolipids in both tuna brain and muscle. The arsenolipid content in brain ranged from 3.8-5.9 mg As per kg, whereas it was substantially lower in muscle (0.3-0.8 mg As per kg) reflecting arsenolipids’ potential to cross the blood brain barrier and accumulate in the fish brain.

Porous Carbon Nitride Thin Strip: Precise Carbon Doping Regulating Delocalized pi-Electron Induces Elevated Photocatalytic Hydrogen Evolution

The photocatalytic efficiency of polymeric carbon nitride is hampered by high carrier recombination rate and low charge transfer. Herein, these issues are addressed by constructing 1D strip-like carbon nitride with a large pi-electron conjugated system from carbon-doping, realizing the synchronization control of its electronic structure and morphology. Nicotinic acid, a monomer with the carboxyl group and pyridine ring, and melamine are selected for assembling the strip-like supramolecular via hydrogen bond under hydrothermal process. Both peripheral pyridine unit and hydrogen bond have significant effect on self-assembly process of nicotinic acid and melamine along one dimension to form a strip-like precursor. Subsequently, 1D thin porous strip-like carbon nitride is obtained by calcination treatment of precursor. The as-prepared 1D strip-like carbon nitride with effective pi delocalization from carbon-doping and porous structure can accelerate charges and mass transfer and provide extra active sites. Both theoretical and experimental results demonstrate that carbon doping (pyridine heterocycle) narrows the bandgap via manipulating the band position and increases the pi electron density. Thus, the 1D porous thin strip-like carbon nitride realizes compelling hydrogen evolution rate (126.2 mu mol h(-1)), far beyond (approximate to 18 fold) the value of polymeric carbon nitride (PCN) (7.2 mu mol h(-1)) under visible light irradiation.
