Abstract
Oligonucleotides with 1,2-diol grouping were prepared from 2'-O-[2-(2,3-dihydroxypropyl)amino-2-oxo-ethyl]uridine 3'-phosphoramidite. The thermal stability of modified DNA duplexes and their ability to form complexes with the p50 subunit of the NF-kappaB transcription factor and (cytosine-5)-DNA methyltransferase SsoII were studied. The periodate oxidation of the l,2-diol grouping of the oligonucleotides resulted in reactive 2'-aldehyde derivatives. The opportunity of their use for the affinity modification of DNA-recognizing proteins was studied.
