General description

KT5823 is a protein kinase inhibitor. It inhibits guanosine monophosphate (GMP)-dependent protein kinase activity (cGK). It is a staurosporine compound, which promotes the thyroid-stimulating hormone and regulates Na+/I− symporter (NIS) expression.

Application

KT 5823 has been used as cyclic guanosine monophosphate (cGMP)-dependent protein kinase (PKG) inhibitor in cortical cultures, cortical neurons and in mouse brain capillary endothelial cells.

Biochem/physiol Actions

Selective inhibitor of PKG.

Nitric oxide synthase (NOS) immunoreactivity is present in goldfish gonadotrophs. The present study investigated whether two native goldfish gonadotrophin-releasing hormones (GnRHs), salmon (s)GnRH and chicken (c)GnRH-II, use NOS/nitric oxide (NO) and soluble guanylate cyclase (sGC)/cyclic (c)GMP/protein kinase G (PKG) signalling

Nitric oxide (NO) plays an important role in acute ischemic preconditioning (IPC). In addition to activating soluble guanylyl cyclase (sGC)/cyclic guanosine monophosphate (cGMP)/protein kinase G (PKG) signaling pathways, NO-mediated protein S-nitros(yl)ation (SNO) has been recently shown to play an essential
