Abstract
Here we present a novel strategy to synthesize O-6 protected morpholino guanosine monomers by trimethylsilylethyl group, 1-(4-azido-phenyl) ethan-1-ol and para methoxy benzyl alcohol, respectively. The introduction of this protecting group increases the solubility of the morpholino nucleoside which is crucial during PMO synthesis. HPLC analysis shows trimethylsilylethyl protected monomer gives better coupling efficiency in PMO synthesis compared to regular one. Moreover the nonpolar nature of the O-6 protected monomer facilitated the guanosine rich PMO block in solution.
