H-ALA-TYR-PRO-GLY-LYS-PHE-NH2 Usage And Synthesis

Uses

AY-NH2 is used in the synthetic preparation of PAR4 agonist peptides towards PAR4 receptor activation.

Biological Activity

ay-nh2 is a selective agonist of par4 with ec50 value of 11 μm [1].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) [2].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 [1]. 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 [3].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 [4].
