Synthesis of oligonucleotides containing the oxidatively modified kappaB site: unique binding affinity to the NFkappaB p50 homodimer

Nucleic Acids Symp Ser. 1999;(42):33-4. doi: 10.1093/nass/42.1.33.


Synthesis of oligonucleotide 26-mers including single 5-formyl-2'-deoxyuridine (1) or 5-formyl-2'-O-methyluridine (2) in place of thymidine at the kappaB site has been accomplished. One of the 26-mers with 1 was critically discriminated by the NFkappaB p50 homodimer in binding.
