  Recognition of Guanine−Guanine Mismatches by the Dimeric Form of 2-Amino-1,8-naphthyridine

  摘要：

  Dimeric 2-amino-1,8-naphthyridine selectively binds to a G-G mismatch with hi-h affinity (K-d = 53 nM). We have investigated a binding mechanism of naphthyridine dimer 2 to a G-G mismatch by spectroscopic studies, thermodynamic analysis, and structure-activity studies for the thermal stabilization of the mismatch. H-1 NMR spectra of a complex of 2 with 9-mer duplex d(CATCGGATG)(2) containing a G-G mismatch showed that all hydrogens in two naphthyridine rings of 2 were observed upfield compared to those C of 2 in a free state. The 2D-NOESY experiments showed that each naphthyridine of 2 binds to a guanine in the, G-G mismatch within the pi -stack. In CD spectra, a large conformational change of the G-G mismatch-containing duplex was observed upon complex formation with 2. Isothermal calorimetry titration of 2 binding to the G-G mismatch showed that the stoichiometry for the binding is about 1:1 and that the binding is enthalpy-controlled. It is clarified by structure-activity studies that show (i) the linker connecting two naphthyridine rings was essential for the stabilization of the G-G mismatch, (ii) the binding efficiency was very sensitive to the linker structure, and (iii) the binding of two naphthyridines to each one of two Gs in the G-G pi -dsmatch is essential for a strong stabilization. These results strongly supported the intercalation of both naphthyridine rings of 2 into DNA base pairs and the formation of a hydrogen bonded complex with the G-G mismatch.
