A series of novel naphthalimide-benzimidazoles was designed and synthesized for the first time and studied for their effect on antiproliferative activity. Some of these compounds possessed good antitumor activity towards the tested cancer cell lines. Noticeably, (diethylamino) ethyl 15 and (dimethylamino) ethyl 23 derivatives displayed superior antiproliferative activity towards human cancer cell lines with MG_MID GI(50) values of 1.43 and 1.83 mu M, respectively. Preliminary investigation revealed that compounds 15 and 23 might bind with ct-DNA through the intercalation mode which is responsible for potent bioactivity. Moreover, transportation behaviour indicated that these molecules could efficiently bind to and be carried by bovine albumin, and the hydrogen bonding and hydrophobic interactions played important roles in interaction with serum albumin.
