Beschreibung

Anwendung

1H-[1,2,4]Oxadiazolo[4,3-a]quinoxalin-1-one has been used as a oxidising agent for  affinity selection-mass spectrometry (AS-MS) compound binding assay, as a soluble guanylate cyclase (sGC) inhibitor to inhibit S-nitroso-N-acetyl-DL-penicillamine (SNAP)-induced cGMP production.

Biochem./physiol. Wirkung

H-[1,2,4]Oxadiazolo[4,3-a]quinoxalin-1-one (ODQ) non competitively inhibits the action of nitric oxide-sensitive guanylyl cyclase and results in a supposedly irreversible oxidation of the prosthetic heme group. ODQ has been used to study the role of cyclic guanosine monophosphate (cGMP) pathway in nitric oxide (NO) signal transduction.

Selective inhibitor of nitric oxide-sensitive guanylyl cyclase.
