The non-exchangeable and imino proton NMR resonances have been assigned of the 1:1 complex of an analogue 2 of Hoechst 33258 1 bound to the decadeoxyribonuycleotide d-[CATGGCCATG]2 by a combination of NOE difference, COSY and NOESYPH techniques. In contrast to Hoechst 33258 which recognizes 5'-AATT sequences exclusively, analogue 2 possesses structural features designed to permit the recognition of GC sites. The NOESY and 1D-NOE experiments place the drug in the minor groove and it is located… CONTINUE READING
