The heterodimer of 2-amino-1,8-naphthyridine and 3-aminoisoquinoline binds to the CTG/CTG triad via hydrogen bonding
Myotonic dystrophy type 1 (DM1) is caused by the aberrant expansion of CTG repeats within the DMPK gene. This study investigated the potential binding of “X-linker-Y” type molecules to the CTG/CTG motif present in CTG repeats, using heterocyclic units X and Y capable of forming complementary hydrogen bonds with nucleobases. Among the tested molecules, the heterodimer of 2-amino-1,8-naphthyridine (X) and 3-aminoisoquinoline (Y) showed significant binding to the CTG/CTG motif. NMR analysis suggested hydrogen-bonded interactions between 3-aminoisoquinoline and thymine.
