✦ Synopsis
The synthesis of three novel derivatives [N-acetyl-Clip-Phen relative to the parent complex [Cu(Clip-Phen)] 2+ . However, the acridine-containing complexes [Cu(4)H] 3+ and [Cu(5)H] 3+ (1), Clip-Phen-hexylaminoacridine (4) and Clip-Phenhexylchloromethoxyaminoacridine ( )] of the bis(phen-exhibited significantly enhanced cleavage efficiencies, which has been attributed to increased affinity of the anthroline) ligand "Clip-Phen", are described. Complexation of these ligands with copper(II) afforded the 1:1 complexes complexes for DNA. UV/Vis-spectral data of the complexes in the presence of calf-thymus DNA was consistent with an as hexafluorophosphate salts. The relaxation of φΧ 174 DNA was used as a DNA cleavage assay, with the following intercalative mode of binding. results. [Cu(1)] 2+ was found to show a diminished activity calation of polyaromatic species between adjacent base
