the reaction of nucleophilic substitution of 14-bromine derivatives of carminomycin and rubomycin with respective nitrogen-containing heterocycles yielded six novel derivatives of carminomycin and rubomycin : 14-n-imidazolyl-carminomycin , 14-carminomycyl-n-pyridinium bromide , 14-carminomycyl-n- ( 3-aminocarbonyl ) -pyridinium chloride , 14-rubomycyl-n- ( 3-amino-carbonyl ) -pyridinium chloride , 14-n-succinimidocarminomycin and 14-n-succinimidorubomycin .
