    摘要: A pyridine compound of the formula I ##STR1## in which R.sup.1 and R.sup.2 independently of each other represent hydrogen or alkyl having from 1 to 4 carbon atoms,R.sup.3 represents hydrogen or alkyl having up to 2 carbon atoms andA represents alkylene having 2 to 4 carbon atoms, n is O or 1,Z is a group of the formula Za, Zb or Zc ##STR2## in which either R.sup.4 is hydrogen andR.sup.5 is phenyl or cinnamyl orR.sup.4, R.sup.5, R.sup.7 and R.sup.8 independently of each other are pyridyl, phenyl or phenyl which is substituted by up to 2 equal or different substituents from the group halogen and alkoxy having up to 2 carbon atoms,R.sup.6 is hydrogen or hydroxy andX is hydrogen, a cyano, amino or nitro group or the group --CO--R.sup.9, in whcih R.sup.9 is hydroxy or alkoxy having from 1 to 4 carbon atoms,and the physiologically tolerable salts of these compounds. The invention also relates to a process for the manufacture of such compounds and to their use in pharmaceutical compositions.
