Abstract
The invention relates to new dihydropyridines which are substituted by an amino group in at least one of the 2- and 6-positions, by a sulphur-containing substituent in the 3-position, by a cyclic substituent in the 4-position and by a carbonyl substituent in the 5-position. The new dihydropyridines are particularly useful as agents which influence the circulatory system. Also included in the invention are procedures for preparation of the new dehydropyridines, compositions containing them and methods for their use.
