Tiivistelmä
{2-Deoxy-3-O-[2-cyanoethoxy(diisopropylamino)phosphino]-5-O-(4,4'-dimethoxytrityl)-alpha-Derythro-pentofuranosyl -N-{2-[4, 7, 10-tris(2,2,2-trifluoroacetyl)-1,4, 7, 10-tetraazacyclododecan-1-yl] ethyl acetamide (I) was prepared and incorporated into a 2'-O-methyl oligoribonucleotide. The hybridization, of this oligonucleotide with complementary 2'-O-methyl oligoribonucleotides incorporating one to five uracil bases opposite to the azacrown structure was studied in the absence and presence of Zn2+ Introduction of Zn2+ moderately stabilized the duplex with U-bulged targets.
