Solid-phase synthesis and evaluation of TAR RNA targeted beta-carboline-nucleoside conjugates.
Four types of beta-carboline-nucleoside conjugates were synthesized. The binding affinities of these beta-carboline-nucleoside conjugates , and to TAR RNA were evaluated by affinity capillary electrophoresis. The data of binding affinities to TAR RNA show that conjugates and are stronger binders than the parent compound . Computer modeling indicates that the beta-carboline-nucleoside conjugate can fit to the UCU three-nucleotide bulge region of TAR RNA.
