2’-F-Arabinonucleic Acid (2’-F-ANA)
Arabinonucleosides are epimers of ribonucleosides with the chiral switch being at the 2’ position of the sugar residue. 2’-F-ANA adopts a more DNA-like B-type helix conformation, not through the typical C2’-endo conformation but, rather, through an unusual O4’-endo (east) pucker. However, the presence of the electronegative fluorine leads to a still significant increase (DTm1.2° C/mod) in melting temperature per modification.1 2’-F-ANA-containing oligonucleotides exhibit very high binding specificity to their targets. Indeed, a single mismatch in a 2’-F-ANA – RNA duplex leads to a DTm of -7.2 °C and in a 2’-F-ANA - DNA duplex a DTm of -3.9 °C.2
The presence of fluorine at the 2’ position in 2’-F-ANA leads to increased stability to hydrolysis under basic conditions relative to RNA and even 2’-F-RNA.1,3 The stability of 2’-F-ANA to nucleases also makes this a useful modification for enhancing the stability of oligonucleotides in biological environments.2 2’-F-ANA hybridizes strongly to target RNA and, unlike most 2’ modifications, induces cleavage of the target by RNase H. Phosphorothioate (PS) 2’-F-ANA is routinely used in these applications due to its increased nuclease resistance. Alternating 2’-F-ANA and DNA units provide among the highest potency RNase H-activating oligomers. Both the “altimer” and “gapmer” strand architectures consistently outperform PS-DNA and DNA/RNA gapmers.4
siRNA oligos were found to tolerate the presence of 2’-F-ANA linkages very well. High potency gene silencing was demonstrated5 with siRNA chimeras containing 2’-F-RNA and/or LNA and 2’-F-ANA. The high efficacy of these chimeras was attributed to the combination of the rigid RNA-like properties of 2’-F-RNA and LNA with the DNA-like properties of 2’-F-ANA.
