PAR-4 Agonist Peptide, amide TFA (PAR-4-AP (TFA)), is a selective activator of the proteinase-activated receptor-4 (PAR-4) that does not affect PAR-1 or PAR-2, and its activity can be inhibited by a PAR-4 antagonist.

| Description | PAR-4 Agonist Peptide, amide TFA (PAR-4-AP (TFA)), is a selective activator of the proteinase-activated receptor-4 (PAR-4) that does not affect PAR-1 or PAR-2, and its activity can be inhibited by a PAR-4 antagonist. |
| In vivo | SCID mice demonstrate a markedly enhanced abdominal response to colorectal distension (CRD), with distension levels ranging from 0.04 to 0.1 mL amplifying the intensity of the EMG response from 384% to 132%, respectively, as compared to BALB/cBy controls (P<0.01; P<0.01; P<0.01; P<0.001). Activation of PAR-4 significantly mitigates this hypersensitivity (P<0.01, P<0.05; P<0.05; P<0.05)[1]. |
