Gα-protein inhibitor. Potently inhibits Gq/11 heterotrimeric G protein signaling. Inhibits ATP/UTP-induced Ca2+ increase in HCAE cells expressing P2Y2 receptor (IC50 = 50 nM); carbachol-induced production of IP1 in CHO cells expressing M1 receptor (IC50 = 95 nM); and ADP-induced Ca2+ increase in platelets, in vitro (IC50 = 2 μM). Also inhibits Gs-induced cAMP elevation and G protein-coupled MAPK/ERK signaling.

How to use

In Vitro:

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.
