New symmetrical 5,8-di:hydroxy-anthraquinone derivatives

摘要

Symmetrical 1,4-bis-(acylaminoalkylamino)-5,8-dihydroxyanthraquinone derivatives of formula (I) and their acid addition salts are new. Z = alkylene; COR = acyl residue of (i) a monocarboxylic acid present in the human organism (or a derivative of such an acid), where the acid or derivative contains a quaternary ammonium group, (ii) a sugar molecule derivative or (iii) neuraminic acid or its derivative.
