NF449 octasodium
Based on 7 publication(s) in Google Scholar
NF449 octasodium is a highly potent P2X1 receptor antagonist, with IC50s of 0.28, 0.69, and 120 nM for rP2X1, rP2X1+5, P2X2+3, respectively. NF449 octasodium is a Gsα-selective G Protein antagonist. NF449 octasodium suppresses the rate of GTP[γS] binding to Gsα-s, inhibits the stimulation of adenylyl cyclase activity, and blocks the coupling of β-adrenergic receptors to Gs.

NF449 octasodium suppressed the rate of GTP[γS] binding to rGsα-s while barely affecting binding to rGiα-1 (IC50=140 nM), inhibits stimulation of adenylyl cyclase activity in S49 cyc membranes (deficient in endogenous Gsα) by exogenously added Gsα-s, and blocks the coupling of β-adrenergic receptors to Gs (EC50=7.9 μM)[2].
