Trisintercalation in DNA by N-[3-(9-acridinylamino)propyl]-N,N-bis[6-(9-acridinylamino)hexyl]amine
Abstract
Viscometry, u.v. spectroscopy, fluorescence, and flow linear dichroism of N-[3-(9-acridinylamino) propyl]-N,N-bis[6-(9-acridinylamino)hexyl]amine (1) in the presence of DNA indicate that it is trisintercalating, and that it slowly ‘crawls’ along the DNA to find its option binding site.
