Uses
BW A868C is a hydantoin compound structurally related to the DP agonist BW245C.
Biological Activity
bw a868c is a novel, selective and potent competitive antagonist of prostaglandin d2 (pgd2) [1].prostaglandin d2 has been widely distributed in rat brain, spinal cord and pituitary and may act as a neuromodulator in the central nervous system [2]. prostaglandin d2 is critical for the development of allergic diseases such as asthma.
in vitro
in glycerol-lysed human platelets, bw245c activated adenylate cyclase in a biphasic manner. bw a868c showed no effect on carbacyclin, iloprost, prostacyclin, pge1 and pge2 at a concentration 1,000 fold that of its kb against pgd2 and bw245c [1]. bw a868c showed no effect on human tp, ip, ep1, ep2, and fp receptors. the ki value for bw a868c is approximately 1.7 nm[1] .in isolated rings of rabbit saphenous vein (rbsv) pre-contracted with 40 mm kcl, bw245c caused concentration-dependent relaxations with an ec50 of 38 nm [3].

Check Digit Verification of cas no
The CAS Registry Mumber 118675-50-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,6,7 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 118675-50:
(8*1)+(7*1)+(6*8)+(5*6)+(4*7)+(3*5)+(2*5)+(1*0)=146
146 % 10 = 6
So 118675-50-6 is a valid CAS Registry Number.
