Description

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
