    摘要: Anthracycline glycosides of general formula 1 and 2: ##STR1## wherein R.sub.1 is hydrogen or a methoxy group; R.sub.2 is hydrogen, a hydroxy group or represents an acyloxy residue of formula 3 --O--COR.sub.5 wherein R.sub.5 is a linear or branched C.sub.1 -C.sub.8 alkyl, an aryl group or a heterocyclic mono or bicyclic ring, each of which may be unsubstituted or substituted with (a) an amino group NR.sub.6 R.sub.7 in which R.sub.6 and R.sub.7 are independently hydrogen or C.sub.1 -C.sub.4 alkyl or (b) a carboxy group; R.sub.3 and R.sub.4 both represent hydrogen or one of R.sub.3 and R.sub.4 is hydrogen and the other is hydroxy group or a group of formula --OSO.sub.2 R.sub.8 in which R.sub.8 may be a linear or branched alkyl group containing from 1 to 6 carbon atoms or an aryl group unsubstituted or substituted by 1 to 3 substituents each of which may independently be a linear or branched alkyl or alkoxy group of from 1 to 6 carbon atoms, a halogen atom or a nitro group; and pharmaceutically acceptable salts thereof; are active as antitumor agents.
