graphicOligonucleotides with novel modifications, 2'-O[2-(methoxy)ethyl]-2-thiothymidine and 2'-deoxy-2'-fluoro-2-thiothymidine, have been synthesized. These modified oligonucleotides exhibited very high thermal stability when hybridized with complementary RNA. 2-O-(2-Methoxy)ethyl-2-thiothymidine modified oligonucleotide phosphodiesters showed enhanced resistance toward nucleases (t(1/2) > 24 h), but 2'-deoxy-2'-fluoro-2-thiothymidine modified oligonucleotide phosphodiesters showed limited stablity to nucleotytic degradation.
