<p>Bis-aminomethyl-anthraquinone derivs. of formula (I) and their salts with acids are new. R1 and R2 are each H or 1-4C alkyl, or R1 and R2 together form a 4-6C alkylene residue so that N(R1)(R2) is a 5- to 7-membered heterocyclic ring which may contain N, O or S as a further heteroatom and which may be substd. by 1-4C alkyl; and R3 is H or OH). The new cpds. can be used for combatting protozoal diseases, in humans and animals, e.g. amoebiasis due to Entamoeba histolytica. In addn., the cpds. have a direct or (due to interferon-induction) indirect activity against influenza and encephalomyocarditis viruses. On account of their interferon-inducing activity, the cpds. can be used against virus and cancer diseases. In addition, the new cpds. (esp. those in which R3 is OH) are effective against trichomoniasis.</p> |
