  (2S,5R/2R,5S)-Aminoethylpipecolyl aepip-aegPNA chimera: synthesis and duplex/triplex stability

  摘要：

  This article reports the design and facile synthesis of novel chiral six-membered PNA analogues (2S,5R/2R,5S)-1-(N-Boc-aminoethyl)-5-(thymin-1-yl)pipecolic acid, aepipPNA IV that upon incorporation into standard aegPNA sequences effected stabilization of complexes with complementary target DNA. Substitution of aegPNA unit by the designed monomer at the C-terminus was more effective than substitution at N-terminus. The stabilizing behaviour improved with degree of substitution and was found to be dependent on their relative positions in the sequence. The six-membered piperidine ring in the design may freeze the rigid chair conformations and the relative stereochemistry of the substituents may in effect direct the complex formation with DNA/RNA by sequence-specific nucleobase recognition. In the present aepipPNA analogues, the L-trans stereochemical disposition of the substituents seems to lead to the favorable pre-organization of the PNA oligomers for complex formation with DNA. The results reported here further expand the repertoire of cyclic PNA analogues. (C) 2004 Published by Elsevier Ltd.
