| Hazard Information | Back Directory | [Description]
ODQ (41443-28-1) is a potent and selective inhibitor of soluble guanylyl cyclase (sGC),?IC50?= 20 nM).1 ODQ acts via competition with NO for the heme site of sGC where it binds irreversibly.2?ODQ does not inhibit NO-mediated macrophage toxicity, an activity that is unrelated to cGMP nor does it inhibit particulate GC.1?ODQ is an extremely useful tool to explore the involvement of the NO-cGMP pathway in cellular signaling and physiologic processes.3-5 | [Chemical Properties]
ODQ is off-white to yellow powder
| [Uses]
1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one inhibits neurite outgrowth and causes neurite retraction in PC12 cells independently of soluble guanylyl cyclase. | [Uses]
ODQ is a selective and potent sGC (soluble guanylyl cyclase) inhibitor.
| [Definition]
ChEBI: 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one is a member of the class of oxadiazoloquinoxalines that is 1H-[1,2,4]oxadiazolo[4,3-a]quinoxaline substituted at position 1 by an oxo group. It has a role as an EC 4.6.1.2 (guanylate cyclase) inhibitor. | [Biological Activity]
ODQ is a potent and selective inhibitor of NO-sensitive guanylyl cyclase.
| [Biochem/physiol Actions]
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. | [storage]
