BW A868C is a hydantoin compound that is structurally related to the DP receptor agonist BW 245C.1,2 BW A868C antagonizes the prostaglandin D2 and BW 245C-induced activation of human platelet adenylate cyclase. It reverses the anti-aggregatory effects of DP receptor agonists in a dose-dependent manner. Likewise, BW A868C antagonizes the accumulation of cAMP in rabbit non-pigmented ciliary epithelial cells.3 It has virtually no effect on human TP, IP, EP1, EP2, and FP receptors. The Ki for BW A868C is approximately 1.7 nM.4
