Pharmaceutically useful nitrogen containing heterocyclic derivatives

Abstract

Bis-basic substituted aromatic polycyclic compounds of the following structure are useful in treating conditions of delayed hypersensitivity: ##SPC1## Wherein [W] represents an aromatic polycyclic nucleus selected from fluoranthene, fluorene, fluoren-9-ol, fluoren-9-one, dibenzofuran, dibenzothiophene, carbazole, N-(lower)alkyl carbazole, xanthene, xanthone, thioxanthene, phenoxathiin, or anthraquinone; Y represents carbonyloxy, carbonylthio, oxygen, divalent sulfur or carbonyl with the provisos that when Y is carbonyloxy or carbonylthio, [W] is other than thioxanthene, phenoxathiin or anthraquinone, when Y is oxygen or divalent sulfur, [W] is other than thioxanthene or phenoxathiin, and when Y is carbonyl, [W] is other than fluoren-9-ol or anthraquinone; A represents a straight or branched alkylene chain of from 1 to 6 carbon atoms with the proviso that when Y is carbonyloxy or carbonylthio, A contains at least 2 straight chain carbon atoms, that is, an ethylene radical; R represents hydrogen, a straight or branched lower alkyl group of from 1 to 4 carbon atoms, phenyl or benzyl; and pharmaceutically useful acid addition salts.
