DNA COMPLEXING AGENTS

摘要

The invention provides a compound of structure (I): wherein X is S, O or NR<SUP>N</SUP>, where R<SUP>N</SUP> is H or alkyl; L is a linker group; Q is a group capable of binding with dsDNA; G and G' are, independently, absent or have between 1 and 20 main chain atoms; FG is a functional moiety comprising at least one O or N atom or a transition metal complex; and R is selected from the group consisting of H, alkyl, alkoxy or OCR<SUP>a</SUP>R<SUP>b</SUP> coupled to an atom in L so as to form a six-membered ring. R<SUP>a</SUP> and R<SUP>b</SUP> are independently H or optionally substituted alkyl.
