title: 9-Acridinylpeptides and 9-acridinyl-4-nitrophenylsulfonylpeptides. Synthesis, binding to DNA, and photoinduced DNA cleavage.
abstract: The preparation of 6-(9-acridinylamino)hexanoic acid DHBT ester and N alpha-Fmoc-N epsilon-(4-nitrophenylsulfonyl)-L-lysine DHBT ester and their application in solid phase peptide synthesis are described. The 9-acridinylamino ligand was shown to confer high DNA affinity, probably by intercalation, to the resulting peptides. The 4-nitrophenylsulfamido ligand furthermore resulted in "photonuclease" activity of some of the modified peptides.
