Photoreactive threading agent that specifically binds to abasic sites in DNA.
We report the synthesis and study of a photoreactive nitrobenzamide containing acridine that specifically interacts at abasic site in DNA by threading intercalation and introduces under irradiation a lesion on the opposite strand at the unpaired pyrimidine.
