title: Sugar modified oligonucleotides: synthesis, nuclease resistance and base pairing of oligodeoxynucleotides containing 1-(4'-thio-beta-D-ribofuranosyl)-thymine.
abstract: XdT12 and dT5XdT6, where X is 1-(4'-thio-beta-d-ribofuranosyl)-thymine, were synthesized. The first oligonucleotide presents a better stability against calf spleen phosphodiesterase than natural dT12. The second one hybridizes with complementary sequence. However the X:A base pairing stability is lower than natural T:A one.
