Chimeric alpha‐beta oligonucleotides as antisense inhibitors of reverse transcription
Résumé
Alpha‐beta chimeric 17‐mer oligodeoxyribonucleotides containing either 5, 10 or 15 beta nucleotides were synthesized. The stability of the RNA/chimera hybrids was only slightly affected by the alpha stretch and by the alpha‐beta link, as was the affinity of the Moloney Murine Leukemia Virus reverse transcriptase for the duplexes. All chimeras inhibited in vitro cDNA synthesis in a cell‐free system to various extent, via the degradation of the RNA target by RNase H.
