Prostane derivatives of the formula ##STR1## wherein R.sub.1 is OR.sub.2 or NHR.sub.3 ; R.sub.2 is hydrogen, C.sub.1-10 alkyl, C.sub.4-10 cycloalkyl, C.sub.6-10 aryl, or a 5 or 6 membered heterocyclic ring having 1-3 hetero atoms selected from O, N and S; R.sub.3 is the residue of a hydrocarbon carboxylic or sulfonic acid of 1-15 carbon atoms; W is (a) an OH-substituted methylene group, (b) a ##STR2## wherein the OH-groups in (a) or (b) can be in the .alpha.- or .beta.-position, or (c) such a group wherein the H atom of the OH group is replaced by the residue of a hydrocarbon carboxylic or sulfonic acid of 1-15 carbon atoms or by a conventional etherifying OH-blocking group; R.sub.4 is OH or hydroxy whose H atom is replaced as defined for W; and R.sub.5, R.sub.6, R.sub.7, R.sub.8, R.sub.9, R.sub.10 and R.sub.11 each independently is hydrogen or alkyl of 1-5 carbon atoms; or R.sub.9 and R.sub.10 together represent a direct bond; and, when R.sub.11 is alkyl, R.sub.10 can also be chlorine; and, for a derivative wherein R.sub.2 is hydrogen, the salts thereof with physiologically compatible bases, have improved prostaglandin activity.
公式为##STR1##的前列腺素衍生物,其中R.sub.1为OR.sub.2或NHR.sub.3;R.sub.2为氢、C.sub.1-10烷基、C.sub.4-10环烷基、C.sub.6-10芳基,或者具有1-3个来自O、N和S的杂原子的5或6元杂环的残基;R.sub.3为1-15个碳原子的烃羧酸或磺酸的残基;W为(a)一个带有OH取代的亚甲基基团,(b)一个##STR2##其中(a)或(b)中的OH基可以位于α-或β-位置,或者(c)这样一个基团,其中OH基的H原子被1-15个碳原子的烃羧酸或磺酸的残基或传统的醚化OH阻滞基团所取代;R.sub.4为OH或其H原子被W定义的取代物替换的羟基;R.sub.5、R.sub.6、R.sub.7、R.sub.8、R.sub.9、R.sub.10和R.sub.11中的每一个独立地为氢或1-5个碳原子的烷基;或者R.sub.9和R.sub.10一起代表直接键;当R.sub.11为烷基时,R.sub.10也可以是氯;对于R.sub.2为氢的衍生物,其与生理兼容碱的盐具有改善的前列腺素活性。
