摘要

Several terpenylquinones derived from 1,4-anthracenedione (1,4-anthracenequinone, AQ) have been prepared by addition or substitution nucleophilic reactions and further transformed into extended polycyclic systems, which mainly kept the 1,4-quinone moiety fused to different nitrogen-heterocyclic rings (pyrrole, imidazole, pyrazine or quinoxaline) into the structure. The compounds synthesized were evaluated for their antineoplastic, antifungal and antiviral activities. GI(50) antineoplastic values remained under mu M levels for AQs, while the heterocyclic derivatives showed antifungal MIC values in the low mu g mL (1) range against yeasts and filamentous fungi. Only few compounds displayed a discrete non-selective antiherpetic activity in the mu g mL(-1) range.
