Heterocyclic compounds of the formula:-
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 -CR1R2- and Y is -0-, -S- or -NR3-, wherein R1, R2 and R3, 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-CR1R2- wherein R1 and R2 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 -CR1R2- 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.
分子式为:- 的杂环化合物
其中 A 为直接连接,或为 1 至 4 个碳原子的亚烷基或 2 至 4 个碳原子的烯基; 其中 X 为-CR1R2-,Y 为-0-、-S- 或-NR3-,其中 R1、R2 和 R3 可以相同或不同,各自为氢或最多 4 个碳原子的烷基;
或 X 是-O-、-S- 或-NH-,Y 是-CR1R2-,其中 R1 和 R2 具有上述含义;
其中Het是含有1、2或3个选自氮、氧或硫原子的杂原子的5-或6-成员杂环,该环可以是未取代的,也可以带有权利要求1所述的一个或两个取代基,条件是当X是-CR1R2-和A是直接连接时,Het不是未取代的2-呋喃基;及其适当的盐类;它们的制造工艺和含有它们的药物组合物。这些化合物具有强心和/或抗高血压活性。
