This invention concerns novel aminopyridinium compounds of the formula I wherein R.sup.1, R.sup.2, R.sup.3, R.sup.5 and R.sup.6 are selected from the following combinations: ##STR1## (a) one of R.sup.2 and R.sup.6 is a basic group selected from amino, alkylamino, dialkylamino of up to eight carbon atoms, pyrrolidino, piperidino and morpholino, or is alkyl, alkenyl, alkoxyalkyl, alkoxy, alkylthio, phenyl, phenylalkyl, cycloalkyl or cycloalkylalkyl; and the other of R.sup.2 and R.sup.6 is hydrogen, alkyl or one of the above defined basic groups; R.sup.1 is alkyl, alkenyl, cycloalkyl, phenyl, phenylalkyl, cycloalkylalkyl; and R.sup.3 and R.sup.5 are independently hydrogen, alkyl or alkenyl; (b) R.sup.2 is a basic group as defined above, R.sup.5 and R.sup.6 together form alkylene or, together with the appendant carbon atoms of the pyridine ring, complete a benzene ring; has any of the meanings defined in (a) above; and R.sup.3 is hydrogen, alkyl or alkenyl; and (c) R2 has any of the meanings defined above and R.sup.6 is a group of the formula --NR.sup.7.A-- in which A together with R.sup.1 forms an ethylene, trimethylene or tetramethylene link and R.sup.7 is hydrogen or alkyl; and R.sup.3 and R.sup.5 have, independently, any of the meanings defined in (a) above; and wherein R.sup.4 is hydrogen, cycloalkylalkyl, alkyl, alkenyl, alkynyl or phenylalkyl; and Q is phenyl; or the group Q.N(R.sup.4)-- together constitutes an azaheterocyclic moietyo; Y is a physiologically acceptable anion; and any one or more of said phenyl or benzene moieties may optionally be unsubstituted or bear one or more selected substituents. The invention also includes certain closely related anhydro-base derivatives which, like the formula I compounds, possess beneficial effects on the cardiovascular system. Also included are pharmaceutical compositions and processes for the manufacture of the various novel compounds.
