title: Synthesis of locked S-type and locked N-type uridine monomer units for incorporation in 2'-5' RNA:3'-5'RNA duplexes.
abstract: To delineate the structural requirements of 2'-5' RNA:3'-5' RNA duplexes, we report the synthesis of N-type locked, S-type locked and 3'-fluoro-2'-phosphoramidite building blocks. The consequent incorporation of these three novel monomers into 2'-5' linked oligomers and their biophysical implications on the stability of the said duplexes will have explicit importance towards development into therapeutic oligomers. The intrinsic stability of 2'-5' phosphodiester linkage as opposed to 3'-5' linked oligomers will be an added advantage.
