1,4-Dihydropyridine derivatives of the formula: ##STR1## wherein R is aryl or heteroaryl; R.sup.1 and R.sup.2 are each independently C.sub.1 -C.sub.4 alkyl or 2-methoxyethyl; X is a 5 or 6 membered nitrogen-containing heterocyclic ring which is substituted with one or more hydroxyl or oxo groups and which may optionally be fused to a further 5 or 6 membered nitrogen-containing heterocyclic ring, and which may optionally be further substituted in the heterocyclic ring or further fused heterocyclic ring; Y is --(CH.sub.2).sub.n --, --CH.sub.2 CH(CH.sub.3)-- or --CH.sub.2 C(CH.sub.3).sub.2 --; and n is 1 to 3 when X is linked to Y by a ring carbon atom, or 2 or 3 when X is linked to Y by a ring nitrogen atom; and their pharmaceutically acceptable salts, and pharmacuetical preparation containing such compounds, have utility as anti-ischaemic and antihypertensive agents.
1,4-二氢吡啶衍生物的化学式为:##STR1## 其中R为芳基或杂环芳基;R.sup.1和R.sup.2分别独立为C.sub.1 -C.sub.4烷基或2-甲氧基乙基;X为含氮的5或6成员杂环环,其上取代有一个或多个羟基或氧代基,且可能选择性地与另一个含氮的5或6成员杂环环融合,在杂环环中或进一步融合的杂环环中可能进一步取代;Y为--(CH.sub.2).sub.n --,--CH.sub.2 CH(CH.sub.3)--或--CH.sub.2 C(CH.sub.3).sub.2 --;当X由环碳原子与Y连接时,n为1至3,或当X由环氮原子与Y连接时,n为2或3;它们的药学上可接受的盐,以及含有这些化合物的药物制剂,具有作为抗缺血和降压药物的用途。
