Ethylenediamine and diethylenetriamine, which are active for RNA hydrolysis, are attached to the 5'-ends of synthetic oligonucleotides by urethane linkages. The resultant artificial ribonucleases selectively hydrolyze the substrate RNA at the target phosphodiester linkage. Acid/base cooperation in the oligoamines for the catalysis is confirmed in terms of kinetic evidences.
