Abstract
The piperazine-substituted pyrroloanthracenes are prepared by reacting either furanoanthracenes with piperazinalkylamines or reacting unsubstituted pyrroloanthracenes first with dihalogenoalkyl compounds and then with appropriately substituted piperazines or by reacting furan derivatives first with piperazinalkylamines and then condensing with anthracenes. The new compounds can be employed as active ingredients in medicaments, in particular in immunomodulators.
