Biological Activity for NS 2028

NS 2028 is a potent soluble guanylyl cyclase (sGC) inhibitor (Ki = 8 nM). Blocks sGC activity in murine cerebellum induced by S-nitroso-glutathione and NMDA (IC50 values are 17 and 20 nM respectively). Inhibits VEGF-induced cGMP accumulation; abolishes VEGF-induced migration in postcapillary venular endothelial cells (CVEC).
