= 3-12 carbon atoms), an "RNA-binding domain" B (bisquaternary salt of 1,4-diazabicyclo[2.2.2]octane), a "catalytic domain" C (histidine residue) and a "linker" L that joins the domains B and C. The effect of the alkyl radical on the catalytic properties of the chemical catalyst was studied using three activated phosphate ester substrates: p-nitrophenyl phosphate, bis-p-nitrophenyl phosphate, and
采用固相法合成了A(n)BCL系列的人工核糖核酸。它们由疏水性烷基基团A(n = 3-12个碳原子),“ RNA结合结构域” B(1,4-二氮杂双环[2.2.2]辛烷双季盐),“催化结构域” C(组氨酸残基)和连接域B和C的“连接基”L。使用三种活化的磷酸酯底物:对硝基苯基磷酸酯,双对硝基苯基,研究了烷基自由基对化学催化剂催化性能的影响。磷酸和胸苷3'-对硝基苯基磷酸酯。
