  The Effect of Universal Fluorinated Nucleobases on the Catalytic Activity of Ribozymes

  摘要：

  Four fluoro modified universal nucleobases have been synthesized. The universal nucleobases 1 and 2, containing a 2,4-difluorobenzene as nucleobase and a 4,6-difluorobenzimidazole, respectively, were chemically incorporated into a selected hammerhead ribozyme sequence which has already been retrovirally expressed as an anti-HIV ribozyme to investigate their effect on the catalytic activity of the ribozymes. The substitution of the natural nucleosides with either 1 or 2 results only in a small decrease of the catalytic activity. The K-m value for the monosubstituted ribozyme with a 2,4-difluorobenzene is 309 nM(-1), the corresponding k(cat) is 2.91 (.) 10(-3) min(-1). A disubstituted hammerhead ribozyme carrying one of each modification has also been synthesized. For a further stabilization of the ribozyme/substrate complex 2'-(beta-aminoethoxy) modified fluorinated nucleosides 15 and 16 have been developed.
