YM 254890 是一种选择性 Gq 信号传导抑制剂。

YM 254890 is a selective Gq signaling inhibitor that strongly inhibits intracellular calcium ion mobilization and serum response element (SRE)-mediated transcription stimulated by several receptors coupled to Gq, but not those coupled to Gi, Gs, or G15; also exhibits antithrombotic and thrombolytic effects in an electrically induced carotid artery thrombosis model in rats; inhibits ADP-induced platelet aggregation in human platelet-rich plasma with an IC50 of <0.6 uM by blocking the P2Y1 receptor-signal transduction pathway.Thrombosis Discontinued.

YM-254890 inhibits platelet aggregation induced by ADP (2, 5 and 20 μM) in human platelet-rich plasma with IC50 values of 0.37, 0.39 and 0.51 μM. ADP mediates platelet aggregation via two G protein-coupled receptors, P2Y1 and P2Y12. The effect of YM-254890 on the P2Y1 and P2Y12 signal transduction pathways using C6-15 cells stably expressing the human P2Y1 or P2Y12 receptors is examined. Stimulation of P2Y1-C6-15 cells by 2MeSADP leads to increases in intracellular calcium mobilization. In this assay, YM-254890 inhibits the increase in [Ca2+]i with an IC50 value of 0.031 μM. In contrast, 2MeSADP-induced inhibition of forskolin-stimulated adenylyl cyclase activity in P2Y12-C6-15 cells is unaffected by YM-254890 at 40 μM.
