Cat.No. 4517 - NS 2028 | C9H5BrN2O3 | CAS No. 204326-43-2
Description: Potent soluble guanylyl cyclase (sGC) inhibitor
Chemical Name: 8-Bromo-1H,4H-[1,2,4]oxadiazolo[3,4-c][1,4]benzoxazin-1-one
Purity: ≥98% (HPLC)

Biological Activity

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).
