Biological Activity for AY 254

AY 254 is a potent PAR2 biased agonist. Selectively activates ERK1/2 signaling (EC50 = 2 nM for ERK1/2 phosphorylation versus 80 nM for Ca2+ release). Reduces cytokine-induced caspase 3/8 activation, promotes scratch-wound healing, and induces IL-8 secretion, in human colorectal cancer (HT29) cells in vitro.
