A new group of compounds having an enhanced ability to inhibit nucleic acid functions have been prepared. These drugs are bis-anthracyclines wherein two anthracycline molecules are linked through their C-13 carbon atoms by amino and/or hydroxy-dicarboxylic acids and their derivatives to form the bis-compounds. Such bis-anthracyclines may be even more effectively delivered to selected sites in a mammalian organism by incorporating the same within uniformly sized liposomes.
