Abstract:

Four naphthalimide derivatives 2-5 modified with various alkylenediamines at 4-position have been designed and synthesized. Their anticancer activities were preliminarily evaluated, which showed potent anticancer activities against A549 cell line with IC50 values lower than 5 µM. Furthermore, the DNA binding properties of 2 with calf thymus (Ct) DNA were investigated by UV-Vis, fluorescence, and circular dichroism (CD) spectroscopies and thermal denaturation experiment. The results showed that compound 2 as the DNA intercalator exhibited strong binding affinity with Ct- DNA.

Keywords: Naphthalimide, DNA intercalator, Alkylenediamines, Anticancer, DNA binding, Fluorescence.
