new series of indenoisoquinoline derivatives was designed and synthesized. The in vitro anti-proliferative activity of these novel compounds was evaluated in HepG2, A549 and HCT-116 cell lines. Compounds 9a, 9b, 10a, 10c, 10e, 18a and 18b manifested potent inhibitory activity against the three tested cancer cell lines. Nineteen compounds were also tested for Top I inhibition at 50 μM. Almost all the
