    摘要： Novel 1,4-dihydropyridine derivatives or the pharmacologically acceptable salts thereof represented by the following general formula (I), and process for preparing the same.
    where R' is dialkoxyalkyl, formyl, formylalkyl, or hydroxyalkyl; R 2 represents alkoxyalkyl, alkenyloxyalkyl, aryloxyalkyl, or aralkyloxyalkyl; R 3 denotes alkyl, haloalkyl, alkoxyalkyl, alkenyloxyalkyl, aryloxyalkyl, aralkyloxyalkyl, or N,N-di-substituted aminoalkyl (the substituents are the same or different alkyl, aralkyl, or aryl); R 4 is alkyl, dialkoxyalkyl, formyl, formylalkyl, or hydroxyalkyl: and R 5 is ortho-, meta-, or paranitro. The compounds of the present invention possess vaso-dilation activities and hypotensive activities, and are expected to be highly useful medicines for the blood circulatory system.

    摘要： Novel compounds having vasodilation and hypotensive effects are represented by the formula
    where R' is halogen, nitro, cyano or lower alkoxy; each of R 2 and R 3 is lower alkyl, lower haloalkyl, lower alkoxyalkyl, aralkyloxyalkyl, aryloxyalkyl, lower alkenoxyalkyl, N,N-di-lower alkylaminoalkyl, N-lower alkyl-N-aralkylaminoalkyl, piperidylalkyl, 4-lower alkyl piperazinylalkyl, norpholinoalkyl or 1-pyrrolidinylalkyl; R' is lower alkyl; A is lower alkylene; and R 5 is hydrogen, lower alkyl, cycloalkyl of 3 to 7 carbon atoms, or aryl unsubstituted or substituted by one or two substituents selected from halogen, nitro, lower alkyl, lower alkoxy, di-lower alkylamino and cyano.
    Also disclosed are processes for their preparation.
