AY-NH2 is a selective agonist of PAR4 with EC50 value of 11 μM .
Protease-activated receptor-4 (PAR4) is a member of PARs and plays an important role in mediating cellular effects of thrombin through acting G-proteins i, 12/13 (Rho and Ras activation) and q (calcium signaling) .
AY-NH2 is a potent PAR4 agonist and has a higher (~10 fold) activity than GYPGKF-NH2. Using rat platelet aggregation assay, it was shown that AY-NH2 had highly platelet aggregation ability than GY-NH2 and GF-NH2 . When tested with platelet-rich plasma harvested from wild-type C57BL6 mice, AY-NH2 treatment exhibited highly agonist activity on PAR4 while had no effect on other PARs .
In male Wistar rats model of paw oedema, i.pl. injection of AY-NH2 markedly reduced the nociceptive score in response to both noxious and non-noxious mechanical stimuli, thus inhibiting carrageenan-induced mechanical hyperalgesia and allodynia .
