A new 9,9′-bianthracene-based thiosemicarbazone (D1) has been successfully synthesized and utilized for chemosensors. The properties of D1 were systematically investigated by UV–Vis, fluorescence titration and theoretical calculations. As a result, D1 exhibits a characteristic fluorescence que...

[3H]Spiroxatrine was examined as a potential ligand for the labeling of 5-HT1A sites in the rat hippocampus. Analysis of the binding of [3H]spiroxatrine in the absence and presence of varying concentrations of three monoamine neurotransmitters revealed that serotonin (5-HT) had high affinity (IC...

The present study was undertaken to determine if spiroxatrine, a reported 5-HT1A antagonist, could block the attenuating effects of fluoxetine (a 5-HT uptake inhibitor) on voluntary ethanol intake by the selectively bred alcohol-preferring P line of rats. Fluoxetine (10 mg/kg, IP) significantly ...

This preliminary study has analyzed the potential ability of the 5-HT1A ligand spiroxatrine to interact with vascular α1-adrenoceptors. Norepinephrine and the selective α1-adrenoceptor agonist, methoxamine, elicited concentration-dependent contractions of rat aortic rings. In contrast, (±)-sp...

A simple, efficient and high-yielding process has been developed for the synthesis of unprecedented symmetrical trans-α,α′-bis(diphenylphosphoryl)cycloalkanols (2a-d), through the p-toluenesulfonic acid-catalyzed reduction of trans-α,α′-bis(diphenylphosphoryl)cycloalkanones with sodium bor...

Spectroscopic profiling in terms of FT-IR, FT-Raman, UV–vis and NMR in addition to reactivity study by density functional theory (DFT) and molecular dynamics (MD) simulations of 3-(4-chlorophenyl)-N,N-dimethyl-3-pyridin-2-ylpropan-1-amine (C16H19ClN2) have been discussed. In order to assign pri...

Two novel cis-dioxotungsten (VI) complexes, [WO2(La)2](1) and [WO2(Lb)2R2Pr](2) [La=2-methoxypyridine, Lb=2,3-dihydroxynaphthalene, R=the six-member ring ion (C5H11N2), Pr=1,3-propanediamine] have been synthesized and characterized by X-ray crystallography, 1H, 13C NMR and IR spectra. It is foun...

The standard (po = 0.1 MPa) molar enthalpies of formation, at T = 298.15 K, for the liquids 2-methoxypyridine, 4-methoxypyridine and 2,6-dimethoxypyridine were determined by static bomb combustion calorimetry. The standard molar enthalpies of vaporization, at T = 298.15 K, were measured by Calve...

In this paper, the novel hemicyanine dye–borate pair, e.g. 2-((o, m, or p)-methoxypyridine)-p-pyrrolidinestyrilium methyl sulfates (MeOSp)–tetramethylammonium n-butyltriphenyl borate (TBAB) were evaluated and employed as the photoinitiating pairs of multiacrylate monomer polymerization. The ki...

The ultraviolet absorption spectrum in the region 340–190 nm in the vapour state as well as in solutions and the fluorescence and phosphorescence spectra in ethanol solution at 77 K have been reported for 2-chloro-6-methoxypyridine. Two systems of absorption bands corresponding to π→π* trans...

The electronic absorption spectrum of 2-methoxypyridine in the vapour and solution phases and 2-methoxy-d3-pyridine in the vapour state in the region 3000–2450 Å and the luminescence spectra of 2-methoxypyridine in ethanol at 77 K have been measured and analysed. The oscillator strength of the ...

The ortho lithiation of 2-,3-, and 4-methoxypyridine was effected using mesityllithium as the metalating base.

The synthesis of a series of pyridones, from their 2-hydroxypyridine or 2-methoxypyridine precursors, is described, along with studies into their reductions to saturated heterocycles. A number of 5-acylpyridones were prepared and were evaluated as substrates for asymmetric transfer hydrogenation...

The Fourier transform infrared (FTIR) and FT-Raman spectra of 2-chloro-6-methoxypyridine have been recorded in the range 3700–400 and 3700–100 cm−1, respectively. The complete vibrational assignment and analysis of the fundamental modes of the compound was carried out using the observed FTIR a...

A convenient methodology which can be tailored to incorporate a chalcogen atom at the C-6 or C-3 position of 2-methoxypyridine (1) was developed. This was achieved by the regioselective lithiation of 1 in the presence and absence of BF3⋅Et2O. The reactions of the 2-methoxypyridine-BF3 adduct wit...

The exothermic reaction of BX3 (X = F, Cl, Br) with 1,1,3,3-tetramethyl-1,3disilacyclobutane (I) gave the ring-cleavage product XMe2SiCH2Me2SiCH2BX2 (II) in almost quantitative yield. The order of activity was BBr3 > BCl3 > BF3. Heating compounds of structure II at 180°C for 40 h did not affect...
