摘要

7-Oxabicycloheptane substituted prostaglandin analogs which are thromboxane A2 (TxA2) receptor antagonists or combined thromboxane A2 receptor antagonists/thromboxane synthase inhibitors useful, for example, in treating thrombotic and vasospastic disease have the structural formula wherein m is 1, 2 or 3; n is 0, 1, 2, 3 or 4; Z is -(CH2)2- or -CH=CH-, with the proviso when Z is -CH=CH-, n is 1, 2, 3 or 4; R is CO2H, CO2lower alkyl, CH2OH, CO2alkali metal, CONHSOR<3>, CONHR<3a> or -CH2-5-tetrazolyl, X is O, S or NH; and where R<1>, R<2>, R<3> and R<3a> are as defined herein.
