  • Hetero-prostaglandin derivatives and processes for preparing them
    Patent number: 4377704
    Abstract: Prostanoic acid derivatives represented by the general formula: ##STR1## in which X represents hydrogen or hydroxy, X.sub.1 represents hydrogen or X and X.sub.1, when they are taken together with the carbon atom to which they are attached, represent a carbonyl group and Z represents hydrogen or hydroxy and pharmaceutically acceptable alkali metal salts thereof.They can be used as bronchodilators and/or inhibitors of blood-platelet aggregation.
    Type: Grant
    Filed: August 3, 1981
    Date of Patent: March 22, 1983
