Hydroxyquinolones are compounds containing a quinoline moiety bearing a hydroxyl group and a ketone. Quinoline or benzo[b]pyridine is a bicyclic compound that consists of benzene fused to a pyridine. 4,6-Dihydroxyquinoline is possibly soluble (in water) and a moderately basic compound (based on its pKa). 4,6-Dihydroxyquinoline exists in all living organisms, ranging from bacteria to humans. 4,6-Dihydroxyquinoline can be biosynthesized from 5-hydroxykynurenamine through its interaction with the enzyme kynurenine 3-monooxygenase. In cattle, 4,6-dihydroxyquinoline is involved in the metabolic pathway called the tryptophan metabolism pathway. 6-Hydroxy-1H-quinolin-4-one Quinoline-4,6-diol 4,6-Quinolinediol C9H7NO2 161.1574 161.047678473 quinoline-4,6-diol 4,6-dihydroxyquinoline 3517-61-1 OC1=CC2=C(O)C=CN=C2C=C1 InChI=1S/C9H7NO2/c11-6-1-2-8-7(5-6)9(12)3-4-10-8/h1-5,11H,(H,10,12) XFALURCRIGINGT-UHFFFAOYSA-N belongs to the class of organic compounds known as hydroxyquinolones.
