  Chemical Synthesis and Properties of Conformationally Fixed Diuridine Monophosphates as Building Blocks of the RNA Turn Motif

  摘要：

  Two intramolecularly cyclized diuridine monophosphates having an amide and a carbamate linker have been synthesized for fixation of the LT-turn structure found in various tRNAs and hammerhead ribozymes. The structural analysis of these cyclic dimers using CD, H-1 NMR, and P-31 NMR spectroscopy shows that they have ri,sid, unstacked conformations. Detailed computer simulations of their 3D structures based on molecular mechanics calculations suggest that a two-state equilibrium between a stretch and a turn conformation exists in favor of the former. The simulation also suggested that the diuridine mono-phosphate containing the carbamate-linker is better as a mimic of the U-turn structure than the amide-linked dimer. The enzymatic properties of these cyclized dimers are also described.
