[Polycationic catalysts for phosphodiester bond cleavage on the basis of 1,4-diazabicyclo[2.2.2]octane].
A number of tetracationic compounds capable of phosphodiester bond cleavage within a 21 -membered ribooligonucleotide were designed and synthesized. The artificial ribonucleases represent two residues of quaternized 1,4-diazabicyclo[2.2.2]octane bearing alkyl substituents of various lengths and connected with a rigid linker. The efficiency of cleavage of phosphodiester bonds in an RNA target depends on the linker structure and the length of alkyl substituent.
