Biological Activity for AC 55541

AC 55541 is a potent and selective protease-activated receptor 2 (PAR₂) agonist (pEC₅₀ = 6.7) that displays no activity at other PAR subtypes or at over 30 other receptors involved in nociception and inflammation. Stimulates cell proliferation, PI hydrolysis and Ca²⁺ mobilization in vitro (pEC₅₀ values are 6.7, 5.9 and 6.6 respectively) and exhibits pronociceptive activity in vivo.
