    摘要: The present invention relates to novel dinitroglycerol esters of fatty acids, hydroxy fatty acids and prostaglandins, and methods for producing them. Dinitroglycerol esters provided by this invention have an improved biological specificity and/or a greater specific activity than the parent compound. The novel prostanoids produced herein may be used as vasodilators, antihypertensive cardiovascular agents, bronchodilators, and they may have uses in obstetrics and gynecology. The dinitroglycerol esters of fatty acids and hydroxy fatty acids may be useful as platelet antiaggregating agents.

    摘要: There is provided a new ester of prostaglandin of the formula ##STR1## wherein R.sub.1 denotes an alkyl group having 1 to 20 carbon atoms; R.sub.2 denotes a hydrogen atom or a lower alkyl group having 1 to 4 carbon atoms; and X denotes a group represented by the formula ##STR2## The new ester dissolves in oil easier than prostaglandin I.sub.2 itself and can easily be emulsified in the form of particles of solution in a vegetable oil. The ester in the fat emulsion is more stable than prostaglandin I.sub.2 and its physiological acts which are the same as prostaglandin I.sub.2 are prolonged.
