摘要:
The invention relates to new aryl-substituted alkoxycarbonyl-1,4-dihydropyridine-5-carboxylic acid esters, processes for their preparation and their use in medicaments, in particular as agents having a cerebral action.
摘要:
Novel phenyl-substituted 1,4-dihydropyridines, prepared by reacting halogenophenyl-aldehydes with &bgr;-ketoesters, if appropriate with isolation of the ylidene compounds and enamines. The substances can be employed as active compounds in medicaments, in particular in cerebrally active compositions.
摘要:
4-Heterocyclyl-substituted dihydropyridines are prepared by reacting appropriate aldehydes with .beta.-keto esters and aminocrotonic acid esters, or by esterifying 4-hetero-cyclyl-substituted dihydropyridinecarboxylic acids. The 4-heterocyclyl-substituted dihydropyridines can be employed in medicaments, in particular for the treatment of disorders of the central nervous system.

摘要:
4-Phenyl-3-substituted 1,4-dihydropyridine esters are prepared by reaction of benzaldehydes with ketoesters and enamines, if appropriate with isolation of the ylidene intermediate products, or by esterification of corresponding dihydropyridinecarboxylic acids with alcohols. The new 4-phenyl-3-substituted 1,4-dihydropyridine esters can be employed as active compounds in medicaments for the treatment of the central nervous system, in particular as cerebral therapeutics.

摘要:
The present invention relates to the new compound rac-isopropyl 2-methoxyethyl 4-(2-chloro-3-cyano-phenyl)1,4 -dihydro-2,6-dimethylpyridine-3,5-dicarboxylate and its pure enantiomers, processes for their preparation and their use as medicaments, in particular for the treatment of cerebral and neuronal disorders, and a new intermediate for their preparation.
摘要:
4-Heterocyclophenyl-substituted dihydropyridines ##STR1## are prepared either by reacting suitable aldehydes with amino esters and .beta.-keto esters, or preparing the heterocyclic substituents of the 4-phenyl by cyclization of corresponding amidines or hydrazides, or esterifying dihydropyridinecarboxylic acids, which are already substituted by heterocyclic radicals, with corresponding alcohols. The 4-heterocyclophenyl-substituted dihydropyridines can be employed in medicaments, in particular for treatment of diseases of the central nervous system.
