Uses
AC 55541 is a selective protease-activated receptor 2 agonist.
Biological Activity
ac 55541 is a potent agonist of par2 with pec50 value of 6.7 and functions range from 200 to 1000 nm [1-3].protease-activated receptor 2 (par2) is a member of the large family of 7-transmembrane receptors and plays an important role in modulating inflammatory responses and acting as a sensor for proteolytic enzymes generated during infection [2].ac 55541 is a selective par2 agonist and has no effect on par1. using a cellular proliferation assay (r-sat), it showed that ac 55541 stimulated nih-3t3 cells proliferation by activating par2 and receptor with f240s mutation constitutively active in all functional assays which nearly 30-fold sensitive to ac 55541 than sligrl and 2-furorl ligrlo [1, 2]. when tested with human corneal epithelial (hce) cells, administration of ac 55541 significantly induced the expression of par2 and inhibited acanthamoeba plasminogen activator (apa) [3].in male sprague-dawley rat model with acute thermal nociception and edema in paw induced by sligrl-nh2 or trypsin, intrapaw administration of ac 55541 induced hind paw edema and thermal hyperalgesia at the doses as low as 30 ng and showed dose-dependent pronociceptive effects [1].

Check Digit Verification of cas no
The CAS Registry Mumber 916170-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,1,7 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 916170-19:
(8*9)+(7*1)+(6*6)+(5*1)+(4*7)+(3*0)+(2*1)+(1*9)=159
159 % 10 = 9
So 916170-19-9 is a valid CAS Registry Number.
