Abstract
We have designed a new type of antisense oligonucleotide, containing two hairpin loop structures with RNA/DNA base pairs (sense (RNA) and antisense (DNA)) in the double helical stem (nicked and circular dumbbell DNA/RNA chimeric oligonucleotides). The reaction of the nicked and circular dumbbell DNA/RNA chimeric oligonucleotides with RNase H gave the corresponding anti-DNA together with the sense RNA cleavage products. These oligonucleotides were more resistant to exonuclease attack. We also describe the anti-Fluv activities of nicked and circular dumbbell DNMA chimeric oligonucleotides.
