Abstract

Several 11-substituted benzo[i]phenanthridine derivatives were synthesized, and their TOP1-targeting activity and cytotoxicity were assessed. Comparative data indicate that TOP1-targeting was often the primary molecular target associated with their cytotoxicity. Several 11-aminoalkyl derivatives, 11-aminocarboxy derivatives as well as the 11-[(2-dimethylamino)ethyl]carboxamide of 2,3-dimethoxy-8,9-methylenedioxybenzo[i]phenanthridine were synthesized and did exhibit considerable cytotoxicity with IC₅₀ values ranging from 20 to 120 nM in the human lymphoblast tumor cell line RPMI8402.
