Abstract: A series of self-complementary decadeoxynucleotides containing a native or modified HaeIII site GGCC (with one or both guanine residues 6-O-cetylated) have been synthesized by the phosphotriester approach. The nonmodified decanucleotide is normally digested with snake venom phosphodiesterase as well as with HaeIII and Bspl restriction endonucleases, whereas the bulky 6-O-alkyl substitutent strongly inhibits, the VPDE hydrolysis and completely prevents digestion with the endonucleases.
