摘要：

To increase the DNA cleavage activity and the cell delivery of the bis(phenanthroline) DNA cleaver "3-Clip-Phen", conjugates between 3-Clip-Phen and the intercalators acridine and 6-chloro-2-methoxyacridine, through amino acid linkers of various length, were prepared. After complexation with CuCl2, the ability of these conjugates to cleave PhiX 174 DNA in the presence of a reductant and air was compared. The results indicated that (i) the coupling of 3-Clip-Phen to an acridine derivative increased the DNA cleavage efficiency of the copper complexes, (ii) the acridine derivatives were more active than 6-chloro-2-methoxyacridine derivatives, (iii) the linker length influenced cleavage efficiency, the highest DNA cleavage activity being obtained for an aminocaproic spacer.
