NS-2028

Guanylate cyclase

-20

NS-2028 is a highly selective soluble Guanylyl Cyclase (sGC) inhibitor (IC50: 30 nM and 200 nM for basal and NO-stimulated enzyme activity) commonly used in nitric oxide signaling pathway research. It inhibits sGC activity in mouse cerebellum homogenates and neuronal NO synthase (IC50: 17 nM and 20 nM), inhibits 3-morpholino-sydnonimine (SIN-1)-elicited cyclic GMP formation in human cultured umbilical vein endothelial cells (IC50: 30 nM), and completely inhibits NO-dependent relaxant responses in non-vascular smooth muscle (1 μM). NS-2028 also decreases vascular endothelial growth factor-induced angiogenesis and permeability.
