Biological Activity for YM 254890

YM 254890 is a 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.
