Abstract
Lanthanide complexes with N,N,N′,N′-tetrakis[(2-pyridyl)methyl]ethylenediamine (TPEN) efficiently hydrolyze a ribonucleotide dimer, ApA, at 35 °C, pH = 7.2. The activity of La3+-TPEN is greater than that of free La3+ ion. The Ln3+-TPEN complexes are sufficiently stable in neutral aqueous solutions (the formation constants are in the range log K/mol−1 dm3 = 3.9 - 6.2). These complexes are promising for the active site of artificial ribonucleases.
