Pyrrolo[3,4-c]-beta-carbolinedione dimers 5-14 were synthesized from furo[3,4-c]-beta-carbolinediones and diamines by solvent-free TaCl5/silica catalyzed reaction under microwave irradiation. The inhibitory property of these target compounds, the starting materials 2, 31, 32, and the N-alkylated pyrrolo[3,4-c]-beta-carbolinediones 16, 17, 20-30 was tested against the relaxation of supercoiled pRB322 DNA by calf thymus topoisomerases I and II. Some of these compounds, especially 7 and 23 proved to be selective inhibitors of topoisomerase I.
