title: Synthesis and properties of 2'-O-methyl-4'-thioRNA.
abstract: In this presentation, we will discuss the synthesis and properties of 2'-O-methyl-4'-thioRNA, an RNA molecule consisting of 2'-O-methyl-4'-thionucleosides. We first synthesized 2'-O-methyl-4'-thiouridine and -cytidine derivatives via 2,2'-O-anhydro-4'-thiouridine. The RNA consisting of 2'-O-methyl-4'-thiopyrimidine nucleosides and 2'-O-methylpurine nucleosides, 2'-OMe-4'-thioRNA, was synthesized on a DNA synthesizer according to the standard phosphoramidite protocol.
