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[1][2].

In Vitro	NF449 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].
In Vivo	At a dose of 10 mg/kg, NF449 inhibits the ex vivo aggregation triggered by 5 g/ml collagen in WT mouse platelets without affecting that induced by 5 μM ADP. At a higher dose (50 mg/kg), NF449 inhibits ex vivo platelet aggregation in response to not only 10 g/ml collagen but also 5 M ADP, indicating nonselective inhibition of the P2Y1 and/or P2Y12 receptor[3].
