Target IC50: 304 nM inhibiting phenylephrine-induced constriction of rabbit aortic rings; 36 nM in blocking collagen-induced aggregation of human platelets
Cell permeable: yes
Primary TargetSoluble guanylate cyclase
General description
A cell-permeable pyrazolopyridinylpyrimidine compound that acts as a selective and potent stimulator of soluble guanylate cyclase (effective dose ~ 0.1 nM to 100 µM using recombinant soluble guanylate cyclase). The mode of activation is NO-independent and appears to be mediated through direct binding to the A1 and A2 subunits. Shown to be effective in treating numerous cardiovascular conditions in animal models. Inhibits phenylephrine-induced constriction of rabbit aortic rings (IC50 = 304 nM) and blocks collagen-induced aggregation of human platelets (IC50 = 36 nM). Does not inhibit phosphodiesterases.
