Abstract
A series of novel naphthalimide derivatives with flexible leucine side chains were designed and synthesized. Their antitumor activities were evaluated against HeLa, A549, P388, HL-60, MCF-7, HCT-8 and A375 cancer cell lines in vitro. The preliminary results showed that most of the derivatives had moderate antitumor activities with the IC50 values of 10-6-10-5 M. More importantly, compounds 8a-c exhibited exclusive antitumor activities against MCF-7 cell line. The interaction between compound 8b and BSA was also investigated. DNA binding experiments showed that these derivatives behaved as DNA intercalating agents. This work provided a novel class of naphthalimide-based lead compounds with exclusive antitumor activities against MCF-7 cell line for further optimization.
