A process for synthesizing phosphoramidites by immobilizing a phosphitylating agent on an activated resin to create a loaded resin and then bringing the loaded resin into contact with a suitable substrate. The phosphoramidites are synthesized within minutes from applying the starting materials. Thus, the process makes it possible to create specific phosphoramidites on-demand as they are needed in further applications. The substrates to be applied are mostly nucleosides, thus to create nucleoside phosphoramidites for subsequent oligonucleotide synthesis.

In this study, we used solid phase synthesis to prepare three kinds of peptides and then formulated their peptide–siRNA complexes and peptide–siRNA conjugates. Both the complexation and conjugation systems were nontoxic and allowed the delivery of siRNA into the cytoplasm without the need for any transfection agents and with subsequent inhibition of gene expression.
