Oligodeoxyribonucleotides of different lengths have been prepared and linked to new stabilizing agents related to the coumarin family. These ODNSAs (OligoDeoxyriboNucleotides with Stabilizing Agents) were tested against acridine connected oligomers of the same sequence. Melting temperature experiments demonstrated that all ODNSAs formed complexes of increased stability with complementary sequences
The title compounds were advantageously synthesized from 2-(dialkylamino)chromones and 1,3-diaminopropane (or 1-amino-3-bromopropane) by amine exchange. The 3-cyano derivatives 5 were directly prepared from 2-(dimethylamino)chromones 1 and KCN by nitro displacement.
