Abstract
1,4-dihydropyridine derivatives represented by the following general formula, ##STR1## in which R.sup.3 is a combination of an unsaturated straight chain hydrocarbon group or derivative thereof connected by a single bond with an unsaturated hydrocarbon group or derivative thereof so that the unsaturated carbon atoms of the two groups are in conjugated relationship. These compounds have a hypotensive action the effective time of which is long, which makes the blood pressure descend slowly, and the toxicity of which is low.
