2-Heptyl-4-hydroxyquinoline N-oxide Chemical Properties, Uses, Production

Description

HQNO (341-88-8) is a naturally occurring antagonist of dihydrostreptomycin. Potent inhibitor of the respiratory chain binding to the mitochondrial cytochrome b protein. HQNO inhibits NADH oxidase (NADH) and Na+-dependent NADH-quinone reductase (NQR).

Uses

HQNO is a streptomycin antagonist. A naturally occurring antagonist of dihydrostreptomycin.

Definition

ChEBI: 2-heptyl-4-hydroxyquinoline N-oxide is an inhibitor of the mitochondrial respiratory chain at cytochrome bc1 and of photosynthetic electron flow immediately before cytochrome b559. It is a monohydroxyquinoline and a quinoline N-oxide.
