NS-2028 is a highly selective soluble Guanylyl Cyclase (sGC) inhibitor with IC50 values of 30 nM and 200 nM for basal and NO-stimulated enzyme activity[1]. NS-2028 inhibits soluble Guanylyl Cyclase activity in homogenates of mouse cerebellum and neuronal NO synthase with IC50 values of 17 nM and 20 nM[1]. NS-2028 inhibits 3-morpholino-sydnonimine (SIN-1)-elicited formation of cyclic GMP in human cultured umbilical vein endothelial cells with an IC50 of 30 nM[1]. NS-2028 is commonly used in the research of nitric oxide signaling pathways, it inhibits NO-dependent relaxant responses in non-vascular smooth muscle completely (1 μM)[1]. NS-2028 reduces vascular endothelial growth factor-induced angiogenesis and permeability[2].

| In Vitro | NS-2028 (10 μM; 24 hours) inhibits 25% cell number in comparation with those grown in the presence of vehicle[2]. NS-2028 (10 μM; 30 mins) attenuates VEGF-induced EC migration by inhibiting p38 MAPK activation[2]. Cell Proliferation Assay[2] Cell Line: HUVEC cells Concentration: 10 μM Incubation Time: 24 hours Result: Decreased cell numbers in culture. Western Blot Analysis[2] Cell Line: HUVEC cells Concentration: 10 μM Incubation Time: 30 mins Result: Attenuated VEGF-enhanced p38 phosphorylation. |
| In Vivo | NS-2028 (Deliver orally; 1 g/L; 8 days) exhibits a significant reduction of new vessel formation in the avascular rabbit cornea in response to VEGF pellet implants[2]. Animal Model: Rabbit[2] Dosage: 1 g/L Administration: Deliver orally; 1g/L; 8 days Result: Inhibits VEGF-induced angiogenesis in vivo. |
