生物活性

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. 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. 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. 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). NS-2028 reduces vascular endothelial growth factor-induced angiogenesis and permeability.

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
