9,11-Azo-13-oxa-15-hydroxyprostanoic acid (AOHP) is shown to be a potent inhibitor of thromboxane synthetase with an IC50 at about 10(-6)M. It also blocked the agonist actions of 9,11-epoxymethano-PGH2 (IC50 9 x 10(-7) M) and TxA2 (IC50 2.4 x 10(-6) M) on human platelet-rich plasma indicating that it also is a PGH2/TxA2 receptor blocker.
