[formula: see text] A new benzo[c]phenanthridinealkaloid, 7-hydroxynitidine, was synthesized by a novel synthetic procedure. The cytotoxic activity of this compound against HeLa S3 cells was strong, but not greater than those of its mother compounds, nitidine and NK109. We also synthesized other 9-oxygenated benzo[c]phenanthridinealkaloids, 7-methoxynitidine, 9-demethylnitidine, nitidine, and fagaronine
