Luminol (5-amino-2,3,-dihydrophthalazine-1,4-dione) is synthesized and its chemiluminescent properties are explored. Both spectral and physical data indicate that the luminol is sufficiently pure, despite a low yield. Chemiluminescence of luminol is observed in the presence of H2O2 and an oxidant enhancer. The quantum yield of the luminol chemiluminescence is determined to be moderate (0.10 ± 0...

a simple and sensitive chemiluminescence-based method was established for the determination of rabeprazole.the proposed method was based on the enhancing effect of rabeprazole on ce(iv)-na2so3 -tb(iii) chemiluminescence reaction. a possible mechanism was discussed for chemiluminescence system by studying uv-vis, fluorescence and chemiluminescence spectra. the effects of various chemical paramet...

We characterized the acid–base properties, electrochemistry, and electrogenerated chemiluminescence (ECL) of neutral red in acetonitrile (MeCN). To determine the acid–base properties, the basic form (NR) of neutral red was prepared and titrated with anhydrous HClO4, yielding pKa = 6.5 in MeCN. NR showed three irreversible electrochemical oxidations and a one-electron reversible reduction. Howev...

BACKGROUND The anti-inflammatory effects of a homeopathic remedy, Traumeel S, have been observed in experimental and clinical studies; however, its antioxidant properties have not been elucidated. The aim of the present study was to evaluate the antioxidant effects of Traumeel S on peripheral blood neutrophils in patients with periodontitis. MATERIAL/METHODS The study was performed using veno...

NO is a free radical with short half-life and high reactivity; due to its physiochemical properties it is very difficult to detect the concentrations precisely. Chemiluminescence is one of the robust methods to quantify NO. Detection of NO by this method is based on reaction of nitric oxide with ozone which leads to emission of light and amount of light is proportional to NO. By this method NO ...

This communication reports the synthesis, chemiluminescence properties, and biological application of KEIO-BODIPY-imidazopyrazine (KBI), a yellow-green chemiluminescent probe for the detection of reactive oxygen species (ROS) generated from living cells.
