摘要: The present invention provides novel bis-naphthalimides characterized by having a linker containing a heteroatom, their preparation, pharmaceutical compositions thereof, and various methods of using the bis-naphthalimides. Particularly preferred bis-naphthalimides have a linker of about 8-16 atoms where the heteroatom is oxygen, sulfur, sulfur oxide or sulfur dioxide. The bis-naphthalimides provided herein have exceptional DNA binding properties and demonstrate cytotoxicity in both in vitro and in vivo tumor models, in particular, against melanoma. Also provided a novel mono-naphthalimides linked to a DNA alkylating agent. These agents are shown to have conformational effects on double stranded DNA and to form covalent adducts after an extended incubation period.
