Abstract
Thromboxane receptor antagonist activity is exhibited by compounds of the formula ##STR1## wherein: V is --(CH.sub.2).sub.m --, --O--, or ##STR2## but if V is --O--or ##STR3## R.sup.3 and R.sup.4 must complete an aromatic ring; W is --(CH.sub.2).sub.2 --, --CH.dbd.CH-- or phenylene; PA1 X is a single bond, --CH.dbd.CH--, --(CH.sub.2).sub.n --, or --O--(CH.sub.2).sub.n --; or X is branched alkylene or --O--branched alkylene wherein W is linked to Y through a chain n carbon atoms long; PA1 Y is --CO.sub.2 H, --CO.sub.2 alkyl, --CO.sub.2 alkali metal, --CH.sub.2 OH, --CONHSO.sub.2 R.sup.5, --CONHR.sup.6, or --CH.sub.2 -5-tetrazolyl; PA1 Z is O or NH; PA1 R.sup.3 and R.sup.4 are each independently hydrogen or alkyl or R.sup.3 and R.sup.4 together complete a ring optionally substituted through a ring carbon with a halo, lower alkyl, phenyl, halo (lower alkyl), halophenyl, oxo or hydroxyl group; and the remaining symbols are as defined in the specification.
