title: Site-selective DNA cleavage by a novel complex of copper-conjugate of Phen and polyamide containing N-methylimidazole rings.
abstract: A novel conjugate of 3-Clip-Phen and polyamide containing three N-methylimidazole (Im) rings was synthesized for the targeting human telomeric repeat of 5'-TTAGGG-3', and the DNA cleaving activity and the sequence selectivity of the complex of copper-conjugate were confirmed by electrospray ionization mass spectrometry.
