Prostanoic acid derivatives of the formula ##STR1## wherein R.sub.1 is a hydrogen atom, alkyl of 1-10 carbon atoms, aryl or --CH.sub.2 --U--V wherein U is a direct bond, carbonyl, or carbonyloxy and V is phenyl or substituted phenyl, e.g. substituted by at least one of phenyl, alkoxy of 1-2 carbon atoms or a halogen atom; one of R.sub.2 and R.sub.3 is hydroxy and the other is a hydrogen atom or R.sub.2 and R.sub.3 collectively are an oxygen atom; A is --CH.sub.2 --CH.sub.2 -- or trans--CH.dbd.CH; B is --CH.sub.2 --CH.sub.2 -- or cis--CH.dbd.CH; D and E collectively are a direct bond, or D is alkylene or 1-5 carbon atoms and E is an oxygen or sulfur atom; R.sub.4 is alkyl of 1-10 carbon atoms, alkyl of 1-5 carbon atoms substituted by unsubstituted or substituted aryl, unsubstituted or substituted aryl, or benzodioxol-2-yl-; X--Y is ##STR2## when one of R.sub.2 and R.sub.3 is a hydroxy group and the other is a hydrogen atom or X--Y is ##STR3## or --CH.dbd.CH-- when R.sub.2 and R.sub.3 collectively are an oxygen atom; and when R.sub.1 is a hydrogen atom, the physiologically acceptable salts thereof with bases, have an activity spectrum similar to but stronger and longer lasting activity than the corresponding natural prostaglandins.
化合物的公式为 ##STR1## 其中R.sub.1是氢原子,1-10个碳原子的烷基,芳基或--CH.sub.2 --U--V,其中U是直接键,羰基或羰氧基,而V是苯基或取代苯基,例如被至少一个苯基,1-2个碳原子的烷氧基或卤素原子所取代;R.sub.2 和R.sub.3 中的一个是羟基,另一个是氢原子,或者R.sub.2 和R.sub.3 共同为氧原子;A是--CH.sub.2 --CH.sub.2 --或trans--CH.dbd.CH;B是--CH.sub.2 --CH.sub.2 --或cis--CH.dbd.CH;D和E共同为直接键,或者D是1-5个碳原子的烷基,E是氧原子或硫原子;R.sub.4是1-10个碳原子的烷基,1-5个碳原子的烷基被未取代或取代的芳基所取代,未取代或取代的芳基,或苯并[1,4]二氧杂环-2-基;X--Y是##STR2##当R.sub.2 和R.sub.3 中的一个是羟基,另一个是氢原子,或者X--Y是##STR3##或--CH.dbd.CH--当R.sub.2 和R.sub.3 共同为氧原子;当R.sub.1是氢原子时,与碱的生理可接受盐具有类似但更强和持续时间更长的活性谱,类似于相应的天然前列腺素。
