Description

General description

A potent G_sα-selective G-protein antagonist. Suppresses the rate of GTPγS binding to G_sα-s (IC₅₀ = 140 nM) but not in G_iα-1. Inhibits stimulation of adenylate cyclase activity in S49 cyc cells (which lack endogenous G_sα) by exogenously added G_sα-s. Also blocks the coupling of β-adrenergic receptors to G_s (EC₅₀ = 7.9 µM). Acts as a reversible competitive antagonist of the human P2X receptor, exhibiting much higher potency at human P2X(1) than at P2X(7) receptors (IC₅₀ = 50 nM vs 40 µM respectively).

A potent G_sα-subunit-selective G-protein antagonist. Suppresses the rate of GTPγS binding to G_sα-s-subunit (IC₅₀ = 140 nM) but not to G_iα-1-subunit. Inhibits stimulation of adenylate cyclase activity in S49 cyc^- cells (which lack endogenous G_sα-subunit) by exogenously added G_sα-subunit. Also blocks the coupling of β-adrenergic receptors to G_s (EC₅₀ = 7.9 µM).
