Prostanoids are described of the formulae ##STR1## (and the salts thereof) in which: X is cis or trans--CH.dbd.CH-- or CH.sub.2 CH.sub.2 --; R.sup.1 is C.sub.1-7 alkyl terminated by --COOR.sup.10 where R.sup.10 is H, C.sub.1-6 alkyl or aralkyl; Y is a saturtaed heterocyclic amino group; and R.sup.4 is thienylalkyl or furanylalkyl in which the ring may be substituted. These compounds inhibit blood platelet aggregation and have bronchodilatory action, and may be formulated for use as anti-asthmatics and antithrombotic agents.
ProSTanoids被描述为以下式子:##STR1##(及其盐),其中:X为顺式或反式-CH.dbd.CH-或CH.sub.2 CH.sub.2-; R.sup.1为C.sub.1-7烷基,末端为-COOR.sup.10,其中R.sup.10为H,C.sub.1-6烷基或芳基烷基;Y为饱和的杂环
氨基;R.sup.4为
噻吩基烷基或
呋喃基烷基,其中环可能被取代。这些化合物抑制血小板聚集并具有支气管扩张作用,可制成用于治疗哮喘和抗血栓的药物。
