YM-254890 is a cyclic depsipeptide that acts as a Gα-protein inhibitor. It 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).
