  1,4-Dihydropyridines of the formula ##STR1## in which n is 0,1 or 2, and R.sup.1 to R.sup.7 can have a wide variety of meanings, which possess inotropic action, and many of which are new, are useful in increasing the influx of Ca.sup.++ into cells, particularly in combatting coronary and vascular diseases, hypertension swelling in the mucous membranes and diseases involving increased blood sugar or an incorrect salt and fluid balance.

  公式为##STR1##的1,4-二氢吡啶，其中n为0、1或2，R.sup.1到R.sup.7可以具有各种含义，具有肌力作用，其中许多是新的，对于增加Ca.sup.++进入细胞特别有用，尤其在对抗冠心病和血管疾病、高血压、黏膜肿胀以及涉及血糖增高或盐和液体平衡不正确的疾病方面。

  1,4-Dihydropyridines bearing carbonyl functions in the 3- and 5-positions, being optionally substituted by lower alkyl in the 6-position, being substituted in the 4-position by lower alkyl, phenyl, substituted phenyl or a heterocyclic group, and being fused through the 1- and 2-positions to a five, six or seven membered cycloalkyl ring, one methylene group of which can be replaced by sulfur, oxygen imino or alkylimino, are antihypertensive agents and coronary vessel dilators. The compounds, of which 6-methyl-4-(3-nitrophenyl)-1,2-pentamethylene-1,4-dihydropyridine-3,5-dica rboxylic acid 3,5-diethyl ester is a representative embodiment, are prepared through condensation of an ylideneacetoacetic acid ester and a cyclic enamino carbonyl derivative.

  在3和5位带有羰基功能的1,4-二氢吡啶，可以在6位上选择性地被低碳基取代，在4位被低碳基，苯基，取代苯基或杂环基所取代，并通过1和2位与五，六或七元环烷基环融合，在其中一个亚甲基可以被硫，氧，亚胺或烷基亚胺取代，是抗高血压药和冠状血管扩张剂。这些化合物，其中6-甲基-4-(3-硝基苯基)-1,2-戊亚甲基-1,4-二氢吡啶-3,5-二羧酸3,5-二乙酯是一个代表性实施例，通过一个亚甲基乙酮酸酯和一个环状烯胺羰基衍生物的缩合制备。
