A new method is reported for the separation of aluminum ions [Al(III)] from interfering elements in parenteral and pharmaceutical solutions (PS) and bottled mineral water (BMW) samples, through solid-phase extraction with 2-methyl-8-hydroxyquinoline (quinaldine) adsorbed onto activated silica gel. While the

Transmissible spongiform encephalopathies (TSEs) are thought to arise from aggregation of a protease resistant protein denoted PrP(Sc), which is a misfolded isoform of the normal cellular prion protein PrP(C). Using virtual high-throughput screening we have selected structures analogous to acridine

We report a novel fluorometric end-point assay for the determination of 1-deoxy-d-xylulose 5-phosphate synthase (DXS) activity based on the reaction of 1-deoxy-D-xylulose 5-phosphate (DX5P) with 3,5-diaminobenzoic acid in an acidic medium to form a highly fluorescent quinaldine derivative. The assay

Type A monoamine oxidase (MAO-A) in human placental mitochondria was competitively inhibited by naturally occurring substances, quinoline and quinaldine, using kynuramine as substrate. Quinoline had a higher affinity for MAO than kynuramine. MAO-A in human brain synaptosomal mitochondria was also
