Four types of β-carbolineânucleoside conjugates were synthesized. The binding affinities of these β-carbolineânucleoside conjugates 4â11, 13 and 15 to TAR RNA were evaluated by affinity capillary electrophoresis. The data of binding affinities to TAR RNA show that conjugates 9 and 13 are stronger binders than the parent compound MC3. Computer modeling indicates that the β-carbolineânucleoside conjugate 13 can fit to the UCU three-nucleotide bulge region of TAR RNA.
我们合成了四种δ-咔啉核苷共轭物。亲和毛细管电泳分析了这些δ-咔啉核苷共轭物 4â11、13 和 15 与 TAR RNA 的结合亲和力。与 TAR RNA 的结合亲和力数据显示,轭合物 9 和 13 的结合力强于母体化合物 MC3。计算机建模表明,δ-咔啉核苷共轭物 13 能与 TAR RNA 的 UCU 三核苷酸隆起区吻合。
