Biological Activity for AMG 333

AMG 333 is a potent and selective TRPM8 antagonist (IC50 values are 13 and 20 nM for hTRPM8 and rTRPM8, respectively). Displays high selectivity over other TRP channels (IC50 >20 μM, TRPV1/V3/V4/A1). Inhibits icilin-induced wet-dog shake in rats and suppresses cold-induced increases in blood pressure in the rat cold-pressor test.
