A 3-cyano-5,4'-bipyridine-1'-oxide of the formula ##STR1## and their pharmaceutically acceptable acid addition salts, wherein R is an amino, alkoxy, oxyalkoxy or chloro residue, have heart stimulating cardiotonic and vasodiolatory properties. They can be preparaed by (a) converting an R-substituted-3-cyano-bipyridine to its corresponding N-oxide, or (b) by substituting an R-residue or an R-unsubstituted precursor of the conpound of fomula (i), and if required, converting the product into its pharmaceutically acceptable acid addition salt.
式子为##STR1##的3-氰基-5,4'-联吡啶-1'-氧化物及其药学上可接受的酸盐,其中R是氨基、烷氧基、氧烷氧基或氯残基,具有心脏兴奋、强心和血管扩张的特性。它们可以通过(a)将R取代的3-氰基联吡啶转化为相应的N-氧化物,或(b)通过取代fomula(i)化合物的R残基或未取代的R前体,并在必要时将产物转化为其药学上可接受的酸盐来制备。
