A convenient 'on line' solid-phase synthesis of oligonucleotides conjugated
at the 3'-end with peptides by means of a polymeric support linking the fi
rst nucleoside via the base has been developed. A 17-mer designed for antis
ense experiments against HIV-1, linking at the 3'-terminus the tripeptide G
ly-Gly-His, was prepared in good yields and characterized by MALDI-TOF mass
spectrometry. (C) 1999 Elsevier Science Ltd. All rights reserved.
