Abstract
The site-specific synthesis of oligonucleotides containing the C8-deoxyguanosine adduct of the highly mutagenic heterocyclic amine 2-amino-3-methylimidazo[4,5-f]quinoline (IQ) has been achieved, and the oligonucleotides were characterized by UV melting temperature analysis, circular dichroism, and UV absorption spectroscopy. Examination of these data indicated that the IQ-adduct is accommodated in dramatically different environments. This sequence-dependent conformational preference is likely to play a key role in the mutagenicity and repair of IQ-modified oligonucleotides.Entities:
