General description

2,8-Quinolinediol is a quinolone derivative. It has been reported as metabolite of 8-hydroxyquinoline-N-oxide in rabbits. Synthesis of 2,8-quinolinediol has been reported. It is reported as one of the six possible forms of 8-hydroxycarbostyril. It has been detected as new UV-absorbing compound (UAC) in cow milk and its structure was elucidated using HRMS and by 1H, 13C and 1H ×13C NMR.It is also known as 8-hydroxycarbostyril or 8-hydroxyquinolin-2(1H)-one.
8-hydroxyquinolin-2(1H)-one has been reported as the tautomeric form of 2,8-quinolinediol. 2,8-Quinolinediol (2,8-Dihydroxyquinoline) has been identified as one of the metabolite of quinolone formed in the culture medium of gram-negative bacteria, Pseudomonas stutzeri.


2,8-Quinolinediol is suitable for use as standard in a study to identify the urinary metabolites for the toxicity related processes and pathogenesis induced by doxorubicin (DOX) to rats by online and off-line LC-MS techniques. It may be used as starting reagent for the preparation of two powerful β2-adrenergic receptor agonists, used for the treatment of asthma:
  • Procaterol
  • Indacaterol

A metabolomics-based systems toxicology approach was used to profile the urinary metabolites for the toxicity related processes and pathogenesis induced by doxorubicin (DOX) to rats. Endogenous metabolite profiles were obtained with ultra performance liquid chromatography-mass spectrometry (UPLC-MS) for rats receiving...

A Pseudomonas sp. isolated from sewage by enrichment culture on quinoline metabolized this substrate by a novel pathway involving 8-hydroxycoumarin. During early growth of the organism on quinoline, 2-hydroxyquinoline accumulated as the intermediate; 8-hydroxycoumarin accumulated as the major metabolite on...
