Abstract
The intercalation and photocleavage of DNA by N-[β-(N′,N′-dimethylamino)ethyl]dithiono-1,8-naphthalimide (2) were extremely effective compared to the use of the oxygen-containing counterpart (1). Their photocleavage action under 366 nm UV light is proposed to proceed by electron transfer from bases to the triplet state of the naphthalimides. The enhancement of the intercalation of DNA and the photocleavage of DNA were also observed for other compounds possessing a thiono or thio group compared with their oxygen-containing counterparts.
