  Catalysis of Diribonucleoside Monophosphate Cleavage by Water Soluble Copper(II) Complexes of Calix[4]arene Based Nitrogen Ligands

  摘要：

  Calix[4]arenes functionalized at the 1,2-, 1,3-, and 1,2,3-positions of the upper rim with [12]ane-N-3 ligating units were synthesized, and their bi-and trimetallic zinc(II) and copper( II) complexes were investigated as catalysts in the cleavage of phosphodiesters as RNA models. The results of comparative kinetic studies using monometallic controls indicate that the subunits of all of the zinc(II) complexes and of the 1,3-distal bimetallic copper(II) complex 7-Cu-2 act as essentially independent monometallic catalysts. The lack of cooperation between metal ions in the above complexes is in marked contrast with the behavior of the 1,2-vicinal bimetallic copper(II) complex 6-Cu-2, which exhibits high catalytic efficiency and high levels of cooperation between metal ions in the cleavage of HPNP and of diribonucleoside monophosphates NpN'. A third ligated metal ion at the upper rim does not enhance the catalytic efficiency, which excludes the simultaneous cooperation in the catalysis of the three metal ions in 8-Cu-3. Rate accelerations relative to the background brought about by 6-Cu-2 and 8-Cu-3 (1.0 mM catalyst, water solution, pH 7.0, 50 degrees C) are on the order of 10(4)-fold, largely independent of the nucleobase structure, with the exception of the cleavage of diribonucleoside monophosphates in which the nucleobase N is uracil, namely UpU and UpG, for which rate enhancements rise to 10(5)-fold. The rationale for the observed selectivity is discussed in terms of deprotonation of the uracil moiety under the reaction conditions and complexation of the resulting anion with one of the copper(II) centers.

  The highest rate acceleration, brought about in the cleavage of the 5'-pCpA bond in hexanucleotide 9 by 50 muM trinuclear complex 5-Cu3 (water solution, pH 7.4, 50 degrees C), amounts to 5 x 105-fold, as based on the estimated background reactivity of the CpA dimer. Selectivity in the cleavage of oligoribonucleotides by copper(II) complexes closely resembles that experienced by ribonuclease A and by

  Ionization of the internucleotidic 2'-hydroxyl group in RNA facilitates transesterification reactions in Group I and II introns (splicing), hammerhead and hairpin ribozymes, self-cleavage in lariat-RNA, and leadzymes and tRNA processing by RNase P RNA, as well as in some RNA cleavage reactions promoted by ribonucleases. Earlier, the pK(a) of 2'-OH in mono- and diribonucleoside (3'-->5') monophosphates had been measured under various nonuniform conditions, which make their comparison difficult. This work overcomes this limitation by measuring the pK(a) values for internucleotidic 2'-OH of eight different diribonucleoside (3'-5') monophosphates under a set of uniform noninvasive conditions by H-1 NMR. Thus the pK(a) is 12.31 (+/-0.02) for ApG and 12.41 (+/-0.04) for ApA, 12.73 (+/-0.04) for GpG and 12.71 (+/-0.08) for GpA, 12.77 (+/-0.03) for CpG and 12.88 (+/-0.02) for CpA, and 12.76 (+/-0.03) for UpG and 12.70 (+/-0.03) for UpA. By comparing the pK(a)s of the respective 2'-OH of monomeric nucleoside 3'-ethyl phosphates with that of internucleotidic 2'-OH in corresponding diribonucleoside (3'-5') monophosphates, it has been confirmed that the aglycons have no significant effect on the pKa values of their 2'-OH under our measurement condition, except for the internucleotidic 2'-OH of 9-adeninyl nucleotide at the 5'-end (ApA and ApG), which is more acidic by 0.3-0.4 pK(a) units.
