pubmed:abstractText |
We synthesized and evaluated by surface plasmon resonance 64 LNA/2'-O-methyl sequences corresponding to all possible combinations of such residues in a kissing aptamer loop complementary to the 6-nt loop of the TAR element of HIV-1. Three combinations of LNA/2'-O-methyl nucleoside analogues where one or two LNA units are located on the 3' side of the aptamer loop display an affinity for TAR below 1nM, i.e. one order of magnitude higher than the parent RNA aptamer. One of these combinations inhibits the TAR-dependent luciferase expression in a cell assay.
