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 ...
The spectroscopy, electrochemistry, and electrogenerated chemiluminescence (ECL) of [(q)(qH)Li]x (qH=8-hydroxyquinolinato) and [(Meq)(MeqH)Li]x (MeQH=2-methyl-8-hydroxyquinolinato) have been investigated. In both acetonitrile and aqueous solutions, [(q)(qH)Li]x and [(Meq)(MeqH)Li]x have absorption maxima at 320 and 309 nm, respectively. When excited at these wavelengths, the complexes emit arou...
To establish whether the use of proteinase inhibitors in the routine determination of in vitro plasma renin activity overestimates the potency of renin inhibitors in vivo, we examined the effects of phenylmethylsulfonyl fluoride and 8-hydroxyquinoline sulfate on the binding to plasma proteins and the respective IC50 values (50% inhibiting concentrations) of three renin inhibitors. All three ren...
The detection of nerve agent simulants is achieved by the photoinduced electron transfer (PET) mechanism. A ‘‘turn-on’’ fluorescence response upon phosphorylation at 8-hydroxyquinoline of norbornene-based triazolyl functionalized 8-hydroxyquinoline (NCHQ) followed by intramolecular rearrangement provides very intense green emission. The detection limit of polymer (PNCHQ) coated paper strips is ...
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.
