摘要：
A method was developed for the synthesis of oligonucleolide-cationic peptide conjugates in solution phase by disulfide bond formation. Precipitation was avoided by the easily removable triethylammonium trifluoroacetate (TEATFAc) salt which served at the same time as a buffer of the reaction mixture. The fast and high yielding disulfide bond formation was due to the Npys thio protecting and activating group of Cys. A solution of the free 5'-thiol modified oligonucleotide obtained from Poly-Pak (TM) purification was used for conjugation.
