Prostaglandin derivatives of the formula ##STR1## in which R.sup.4, R.sup.5, R.sup.6 and R.sup.7 each are hydrogen or lower alkyl, X is hydroxy and Y is hydrogen or X and Y together are oxo, Z is CH.sub.2 CH.sub.2 or trans CH.dbd.CH, m is an integer from one to three and n is an integer from two to five, with the proviso that at least one of R.sup.4, R.sup.5 or R.sup.6 is hydrogen, are disclosed together with a process for their preparation. The compounds in which Z is CH.sub.2 CH.sub.2 and the process are new. The new derivatives possess hypotensive, antihypertensive, bronchospasmolytic, gastric acid secretion inhibiting, abortifacient, estrus synchronizing and ovulation regulating properties. These compounds also inhibit the aggregation of platelets and promote the disaggregation of aggregated platelets. Methods for their use are also disclosed.
公开了式子为##STR1##的前列腺素衍生物,其中R.sup.4、R.sup.5、R.sup.6和R.sup.7分别为氢或低碳基,X为羟基,Y为氢或X和Y一起为氧代,Z为CH.sub.2 CH.sub.2或顺式CH.dbd.CH,m为1到3的整数,n为2到5的整数,但至少R.sup.4、R.sup.5或R.sup.6之一为氢。公开了制备它们的方法。其中Z为CH.sub.2 CH.sub.2的化合物和制备方法是新的。这些新衍生物具有降压、抗高血压、支气管痉挛、抑制胃酸分泌、引产、发情同步和促进排卵的性质。这些化合物也可以抑制血小板聚集并促进聚集的血小板的解聚。公开了它们的使用方法。
