BW A868C Chemical Properties,Usage,Production

Uses

BW A868C is a hydantoin compound structurally related to the DP agonist BW245C.

Definition

ChEBI: BW A868C is an imidazolidine-2,4-dione.

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].
