PSB-1114 tetrasodium is a potent, enzymatically stable, and subtype-selective P2Y2 receptor agonist with an EC50 of 134 nM. PSB-1114 tetrasodium displays >50-fold selectivity versus the P2Y4 (EC50 of 9.3 μM) and P2Y6 (EC50 of 7.0 μM) receptors[1].

Target	EC50: 134 nM (P2Y2 receptor), 9.3 μM (P2Y4 receptor); 7.0 μM (P2Y6 receptor)[1]
In Vitro	PSB-1114 (4-Thio-β,γ-difluoromethylene-UTP; compound 14g) displays >60-fold selectivity versus P2Y4 and P2Y6 receptors. Because of its high potency, selectivity, and expected metabolic stability toward ectonucleotidases, in particular NTPDases, PSB-1114 may be a useful pharmacological tool for studying P2Y2 receptors[1].
