Binding of the coagonist glycine to the N-methyl-D-aspartate (NMDA) subtype of glutamate receptors is potently antagonized by 2-carboxy-4-hydroxyquinolines. We show that closely related derivatives, 4-hydroxy-quinolines and 4-hydroxquinoline-3-carboxylic acids, antagonize the agonist response of the recombinant inhibitory glycine receptor (GlyR). In Xenopus laevis oocytes expressing the GlyR al...

The first examples of triarylboron-functionalized 8-hydroxyquinoline ligands and their aluminium complexes have been synthesized. These luminescent derivatives of the well-known electron transport material tris(8-hydroxyquinoline)aluminium (Alq(3)) display enhanced electron-accepting ability relative to Alq(3), and can also be used as an indicator for small F(-) and CN(-) anions.

Two tetranuclear [Zn4Cl2(ClQ)6]·2DMF (1) and [Zn4Cl2(ClQ)6(H2O)2]·4DMF (2), as well three dinuclear [Zn2(ClQ)3(HClQ)3]I3 (3), [Zn2(dClQ)2(H2O)6(SO4)] (4) [Zn2(dBrQ)2(H2O)6(SO4)] (5), complexes (HClQ = 5-chloro-8-hydroxyquinoline, HdClQ 5,7-dichloro-8-hydroxyquinoline HdBrQ 5,7-dibromo-8-hydroxyquinoline) were prepared possible anticancer or antimicrobial agents characterized by IR spectroscopy,...

1. Degradation of 125I-labelled [Ile5]-angiotensin I and unlabelled angiotensin I was studied during incubation of rat plasma treated with disodium ethylenediaminetetra-acetate (disodium EDTA) at 37 degrees C, pH 6.5, for 1 h with 8-hydroxyquinoline, phenylmethylsulphonyl fluoride or di-isopropyl fluorophosphate. 2. Isoelectric focusing showed approximately 100, 59--66 and 10--31% preservation ...

Azo dye of quinoline named 5-(3-pyridylazo)-8-hydroxyquinoline (PAHQ) was prepared via coupling reaction diazonium salt 3-aminopyridine and 8-hydroxyquinoline. he PAHQ characterized by elemental analysis, mass spectroscopy 1H-NMR. The complexes were under 2:1 (L:M) mole ratio. infrared spectroscopy, UV-Vis, molar conductance, magnetic susceptibility. IR spectra data indicate that ligand is bid...

in order to study the physiological effects of some of the essential oils in comparison with 8-hydroxyquinoline in cut lisianthus flowers (eustoma grandiflorum l.), an experimental was conducted in a completely randomized design with three replications. traetments included 8-hydroxyquinoline, essential oil of australian cheesewood (pittosporum undudatum) and rosmary oil(rosmarinus officinalis) ...

8-Hydroxyquinoline-based receptors 1-3, containing a trisubstituted triethylbenzene core, were prepared and their binding properties towards glycosides were evaluated. (1)H NMR and fluorescence titrations as well as binding studies in two-phase systems, such as dissolution of solid carbohydrates in apolar media and phase transfer of sugars from aqueous into organic solvents, revealed β- vs.α-an...

The numerous methods for determining magnesium in biological fluids that have been reported in the past have varied from chemical to spectrochemical techniques. Among these various procedures have been included gravimetric, calorimetric, and titrimetric techniques. The gravimetric micromethod based on the precipitation of magnesium B-hydroxyquinoline in hot ammoniacal solution, first utilized b...
