1. NMR structral studies on ruthenium complexes binding to DNA
Sammanfattning : The Ru-complex Λ,Λ-[bidppz(bipy)4Ru2]4+ (Λ,Λ-B) exhibits multiple modes of interactions with the palindromic DNA dodecamer [d(CGCGAATTCGCG)]2, however excluding any type of intercalation as shown by both optical spectroscopy and NMR. NMR observation of Λ,Λ-B titration into a DNA solution results in both a transient binding, with observation of fast exchange for protons located near the ends of the DNA duplex, and a more stable interaction in the DNA minor groove indicated by a slow exchange mechanism and binding sites for G2, G4 and A5 of the same DNA strand.
