内容記述タイプ Abstract
内容記述 Previously, we reported our investigations of the interaction between a cyclic naphthalene diimide derivative (cNDI 1) and double stranded DNA (dsDNA) (Bioorg. Med. Chem.2014, 22, 2593). Here, we report the synthesis of the novel cNDI 2, which has shorter linker chains than cNDI 1. We performed comparative investigations of the interactions of both cNDI 1 and cNDI 2 with different types of dsDNA, including analysis of their thermodynamics and kinetics. Interactions between the cNDIs and calf thymus DNA (CT-DNA), poly[d(A-T)]2, or poly[d(G-C)]2 were explored by physicochemical and biochemical methods, including UV–Vis spectroscopy, circular dichroism (CD) spectroscopy, stopped-flow kinetics, and a topoisomerase I assay. Upon addition of cNDIs to CT-DNA, the existence of an induced CD signal at approximately the wavelength of the naphthalene diimide chromophore and unwinding of the DNA duplex, as detected by the topoisomerase I assay, revealed that cNDIs bound to the DNA duplex. As indicated by the steric constraint in the formation of the complex, bis-threading intercalation was the more favorable binding mode. UV–Vis spectroscopic titration of the cNDIs with DNA duplexes showed affinities on the order of 105–106 M−1, with a stoichiometry of one cNDI molecule per four DNA base pairs. Thermodynamic parameters (ΔG, ΔH, and ΔS) based on the van’t Hoff equation indicated that exothermic and entropy-dependent hydrophobic interactions played a major role in the reaction. Stopped-flow association and dissociation analysis showed that cNDI interactions with poly[d(G-C)]2 were more stable and had a slower dissociation rate than their interactions with poly[d(A-T)]2 and CT-DNA. Measurement of ionic strength indicated that electrostatic attraction is also an important component of the interaction between cNDIs and CT-DNA. Because of its longer linker chain, cNDI 1 showed higher binding selectivity, a more entropically favorable interaction, and much slower dissociation from dsDNA than cNDI 2.
