TRAP-6 amide is a peptide agonist of proteinase-activated receptor 1 (PAR1).1 It induces platelet aggregation in vitro (EC50 = 0.15 µM). TRAP-6 amide (30 µM) induces relaxation of isolated guinea pig internal anal sphincter strips.2 It also increases cigarette smoke extract-induced IL-8 release from isolated human bronchial epithelial cells when used at a concentration of 50 µM.3
