Dibenzo[c,h][1,5]naphthyridinediones as topoisomerase I inhibitors: design, synthesis, and biological evaluation.


ABSTRACT: Dibenzo[c,h][1,5]naphthyridinediones were prepared via a novel synthetic pathway. The compounds were designed as topoisomerase I (Top1) inhibitors based on the indenoisoquinoline series of drugs. The results of biological evaluation demonstrate that, unlike very closely related dibenzo[c,h][1,6]naphthyridinediones, dibenzo[c,h][1,5]naphthyridinediones retain the Top1 inhibitory activity of similarly substituted indenoisoquinolines.
