Abstract: A series of polyamine derivatives of naphthalimide(3a~3d) to be used as antitumor agents was synthesized. The biological and spectroscopic evaluations showed that compounds 3a~3d could used as DNA intercalators and had stronger cytotoxic activity and better selectivity than those of amonafide against cancer cells in vitro. The IC50 for antiproliferative activity of compound 3b on four cancer cells were 7.80, 5.08, 9.78 and 9.27 μmol/L, respectively. High content screening(HCS) results revealed that the as-prepared compounds might produce cytotoxicity through apoptosis via mitochondrial pathway.

Key words: Naphthalimide, DNA intercalator, antitumor, High Content Screening
