Compounds of the formula:
wherein
R is alkyl of 1 to 12 carbon atoms, cyclopentyl, cyclohexyl, cyclopentylloweralkyl or cyclohexylloweralkyl;
Z is ethylene or propylene, optionally substituted with a single substituent which is lower alkyl;
A is the integer 1, 2, or 3; and the pharmaceutically acceptable acid addition salts thereof, said compounds being useful as spermicidal, antimicrobial and anticonvulsant agents and thromboxane synthetase inhibitors.
A new class of compounds combining thromboxane-A2 (TxA2) receptor antagonism and thromboxane synthase inhibition is described. A first series of (E)- and (Z)-[[[2-(1H-imidazol-1-yl)ethylidene]amino]oxy]pentanoic acids showed relevant thromboxane synthase inhibition associated with weak TxA2 receptor antagonism, while a series of (+/-)-(E)-[[[2-(1H-imidazol-1-yl)-3-phenylpropylidene]amino]oxy] pentanoic
