Abstract: The invention relates to novel aminoacridine-.alpha.,.beta.-(D)- and -(L)-N-glycoside derivatives, the salts thereof and to a novel process for the preparation of such compounds and salts. The novel compounds have the formula I ##STR1## wherein R is hydrogen or a group of the formula II ##STR2## wherein n=0 or 1, p=1 or 2, A.sup.-p is an anion, preferably halogenide, R.sup.1 is hydrogen or a methyl group andR.sup.2 is hydrogen or a sugar residue, or R is dimethylamine,and the two substituentsX and X.sup.1 are identical or different and stand for hydrogen, a group of the formula II, dimethylamine, halogen, a C.sub.1-4 alkyl group, a C.sub.1-4 alkoxy group, for a nitro-, cyano-, carbomethoxy-, carbamoyl-, phenyl- or a C.sub.1-4 alkylphenyl group,with the restriction that at least one of the substituents R, X and X.sup.1 represents a group of formula II with R.sup.2 =sugar residue, andR.sup.3 is hydrogen or a C.sub.1-5 alkyl group.
