Heterocyclic compounds of the formula: ##STR1## wherein A is a direct link, or is alkylene of 1 to 4 carbon atoms or alkenylene of 2 to 4 carbon atoms; wherein either X is --CR.sup.1 R.sup.2 -- and Y is --O--, --S-- or --NR.sup.3 --, wherein R.sup.1, R.sup.2 and R.sup.3, which may be the same or different, each is hydrogen or alkyl of up to 4 carbon atoms; or X is --O--, --S-- or --NH-- and Y is --CR.sup.1 R.sup.2 -- wherein R.sup.1 and R.sup.2 have the meanings stated above; and wherein Het is a 5- or 6- membered heterocyclic ring containing 1, 2 or 3 heteroatoms selected from nitrogen, oxygen or sulphur atoms, which ring may be unsubstituted or may bear one or two substituents as set out in claim 1, provided that when X is --CR.sup.1 R.sup.2 -- and A is a direct link, Het is not unsubstituted 2-furyl; and salts thereof where appropriate; processes for their manufacture and pharmaceutical compositions containing them. The compounds possess cardiotonic and/or antihypertensive activity.
式为:##STR1##其中A是直链,或是1到4个碳原子的烷基或2到4个碳原子的烯基烷基;其中X为--CR.sup.1 R.sup.2 --,Y为--O--,--S--或--NR.sup.3 --,其中R.sup.1,R.sup.2和R.sup.3,可以相同也可以不同,分别为氢或碳数不超过4的烷基;或者X为--O--,--S--或--NH--,Y为--CR.sup.1 R.sup.2 --,其中R.sup.1和R.sup.2的含义如上所述;且Het是一个含有1、2或3个氮、氧或硫原子的5或6元杂环环,该环可以是未取代的或带有一个或两个取代基,如权利要求书所述,但当X为--CR.sup.1 R.sup.2 --且A为直链时,Het不是未取代的2-呋喃基;以及相应的盐;其制备方法和含有它们的药物组合物。这些化合物具有心力学和/或降压活性。
