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].

Check Digit Verification of cas no
The CAS Registry Mumber 352017-71-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,2,0,1 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 352017-71:
(8*3)+(7*5)+(6*2)+(5*0)+(4*1)+(3*7)+(2*7)+(1*1)=111
111 % 10 = 1
So 352017-71-1 is a valid CAS Registry Number.
