    • A series of compounds of the 1,4-dihydropyridine class with a 3-carboxylate group linked to an alkyleneaminoalkylene heteroatom have been prepared possessing the general formula ##STR1## wherein R.sup.2, R.sup.5 and R.sup.6 are independently selected from lower (C.sub.1-4)alkyl, hydroxy-lower-alkylene, lower alkoxy-lower-alkylene, lower alkylamino-lower-alkylene or lower dialkyl-amino-lower-alkylene; R.sup.7 is selected from hydrogen, lower alkyl, phenyl-lower-alkylene, or phenylthio-lower-alkylene; n is the integer 2 or 3; X is a chemical bond, --O--, --S--, ##STR2## or --NR.sup.9 -- wherein R.sup.9 is hydrogen, lower alkyl, phenyl, or phenyl-lower-alkylene with the proviso that when X is a chemical bond, Z is a 3-indolyl ring; and Z is selected from the group consisting of phenyl substituted with 1 to 3 substituents independently chosen from among hydrogen, lower alkyl, or lower alkoxy, phenyl-lower-alkylene, or 3-indolyl.Compounds of this series possess calcium channel blocking properties, afford protection against ischemia and inhibit aggregation of blood platelets.
    • 已经制备了一系列具有与亚烷基氨基亚烷基杂原子连接的3-羧酸酯基的1,4-二氢吡啶类的化合物,其具有通式“IMAGE”,其中R 2,R 5和R 6独立地选自低级(C 1-4)烷基 ,羟基 - 低级 - 亚烷基,低级烷氧基 - 低级 - 亚烷基,低级烷基氨基 - 低级 - 亚烷基或低级二烷基 - 氨基 - 低级 - 亚烷基; R 7选自氢,低级烷基,苯基 - 低级亚烷基或苯硫基 - 低级 - 亚烷基; n是整数2或3; 其中R为氢,低级烷基,苯基或苯基 - 低级亚烷基,条件是当X为化学键时,Z为化学键,-O - , - S-, 3-吲哚基环; 并且Z选自被1至3个独立地选自氢,低级烷基或低级烷氧基,苯基 - 低级亚烷基或3-吲哚基的取代基取代的苯基。 该系列化合物具有钙通道阻断性质,提供防止缺血和抑制血小板聚集的保护作用。
