Structure of the thromboxane receptor antagonist EP 092.
7-(3-[1-(4-Phenylthiosemicarbazono)ethyl]-bicyclo[2.2.1]hept-2- yl)-5-heptenoic acid, C23H31N3-O2S, Mr = 413.7, monoclinic, P2(1)/a, a = 12.9650 (7), b = 11.2081 (6), c = 16.8941 (12) A, beta = 110.452 (5) degrees, V = 2300.2 A3, Z = 4, Dx = 1.194 g cm-3, Mo K alpha, lambda = 0.71073 A, mu = 1.55 cm-1, F(000) = 888, T = 298 K. Final R = 0.0472 with 2778 independent data. EP 092 is a thromboxane receptor antagonist akin to many other analogues of the thromboxane A2 [Wilson & Jones (1985). Adv. Prostaglandin Thromboxane Leukotriene Res. 14, 393-425].
