(EN) A series of compounds useful in treating cardiovascular disorders due to the combined expression of both B-block and calcium-block activity by these agents. This useful combination of actions is effected by a novel combination of structural subunits forming these compounds. Essentially, B-blocking aryloxypropanolamine moieties are attached via their aryl ring or amino nitrogen at the Z position of the following formula (I) wherein x is oxygen or nitrogen and the remainder of the substituents are defined herein. These compounds are prepared from new 4-ary-1,4-dihydropyridine intermediate compounds.(FR) Série de composants utiles dans le traitement de troubles cardiovasculaires par l'activité combinée de B-blocage et de blocage de calcium de ces agents. Cette combinaison utile d'activités est obtenue grâce à une nouvelle combinaison de sous-unités structurales formant ces composés. Essentiellement, des moitiés d'aryloxypropanolamine B-bloquante sont attachées via leur anneau aryle ou azote amino en position Z de la formule (I), où X est oxygène ou azote et le reste des substituants y est défini. Ces composés sont préparés à partir de nouveaux composés intermédiaires de 4-aryl-1,4-dihydropyridine.

This invention provides compounds useful for treating coronary insufficiency, hypertension, angina pectoris, cardiac arrythmia, heart attack or coronary vasospasm and represented by the general formula: ##STR1## R.sub.1 and R.sub.2 are each independently selected from the group consisting of lower alkyl, N-alkylphthalimido and derivatives of N-alkylphthalimido, wherein said N-alkyl group comprises at least 2 carbon atoms; A is a straight or branched chain hydrocarbon moiety containing from 1 to 12 carbon atoms and from 0 to 2 double bonds; R.sub.3 is selected from the group of radicals consisting of hydrogen, --NH.sub.2 and --NCS; R.sub.4 is an aryl or heteroaryl radical; and R.sub.5 is a lower alkyl radical or A--R.sub.3 ; provided that when R.sub.3 is a hydrogen radical at least one of R.sub.1 and R.sub.2 is not lower alkyl, including both pure enantiomers as well as mixtures thereof; and pharmaceutically-acceptable salts thereof.
