Abstract Three new ring systems, pyrido[2′,3′:3,4]pyrrolo[1,2- a ]quinoxalines, pyrido[3′,2′:3,4]pyrrolo[1,2- a ]quinoxalines and pyrido[2′,3′:5,6]pyrazino[2,1- a ]isoindoles, were synthesized through an aza-substitution on the already active isoindolo-quinoxaline system and in particular in the position 7 or 4 of the isoindole moiety and in position 5 of the quinoxaline portion. All new compounds were screened by the National Cancer Institute (Bethesda, MD) against a panel of 60 human tumor cell lines. Biological results of the most active derivatives, with pGI 50 values between 7.09 and 7.27, confirmed the importance of the presence of methoxy substituents for biological activity. The anti-proliferative effect of selected quinoxalines was associated with apoptosis of the cells and arrest in G2/M phase of the cell cycle. DNA binding properties of the compounds was also assessed to investigate the possible mechanism of action.
