Amino-substituted imidazo[1,2-a:3,4-a']diquinolin-15-ium salts having the formula I: ##STR1## wherein R.sub.1 is hydrogen, lower alkyl, C.sub.4 -C.sub.6 cycloalkyl, di(lower alkyl)amino, 1-azetidinyl, 1-pyrrolidinyl, 1-piperidinyl, methyl-1-pyrrolidinyl, methyl-1-piperidinyl, 4-morpholinyl or 2,2-dimethylhydrazino; R.sub.2 is hydrogen, lower alkyl, lower alkylamino, di(lower alkyl)amino, C.sub.4 -C.sub.6 cycloalkylamino, lower alkoxy(lower alkyl)amino, 1-azetidinyl, 1-pyrrolidinyl, 1-piperidinyl, methyl-1-pyrrolidinyl, methyl-1-piperidinyl, hexahydro-1H-azepin-1-yl, 4-morpholinyl, benzylamino, N-methylbenzylamino or 2-phenylethylamino; R.sub.3 is hydrogen or methyl; X is an anion; with the proviso that at least one of R.sub.1 and R.sub.2 is other than hydrogen, lower alkyl or C.sub.4 -C.sub.6 cycloalkyl; and with the further proviso that when R.sub.2 is dimethylamino, at least one of R.sub.1 and R.sub.3 is other than hydrogen, and intermediates used in the preparation thereof are disclosed. The compounds of the invention are prepared by amination of the corresponding chloro or fluoro-substituted imidazo [1,2-a:3,4-a']diquinolin-15-ium salts; either the halo substituted intermediates or the amino substituted salts may be further treated, typically using ion exchange techniques to obtain a variety of physiologically acceptable amino-substituted [1,2-a:3,4-a']diquinolin-15-ium salts which exhibit antifungal activity.
