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.

Application

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 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
