摘要：
The interactions of each of three phenanthroline derivatives 1, 2 and 3 with the human telomeric i-motif DNA were investigated. The results suggest these compounds are potent binders. The compounds could stabilize the structure of i-motif DNA by pi-pi stacking. Moreover, the binding constants of the compounds with i-motif DNA were (2.71-8.12)x10(4) L.mol(-1), and the binding stoichiometry ratio was 1:1. CD studies reveal that the binding by phenanthroline compounds perturbs the conformation of i-motif DNA.
