Prooligonucleotides with alternating S-Acyl-ThioEthyl (SATE) phosphotriester and phosphodiester linkages or a gap were synthesized by elimination of cyanoethyl group with non-nucleophilic base DBU. Their half-lives in the presence of Pig Liver Esterases (PLE) and in total cell extract were determined.
