  (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.

  activated zinc gives the corresponding alkylzinc iodide 14, which reacts under palladium catalysis with a range of electrophiles (aryl iodides and acid chlorides) to give the corresponding adducts 19 and 22. While the reactions with aryl iodides provide acceptable yields in THF as solvent, the corresponding reactions with acid chlorides requires dimethoxyethane or, preferably, a combination of toluene

  Prolyl oligopeptidases cleave peptides on the carboxy side of internal proline residues and their inhibition has potential in the treatment of human brain disorders. Using our docking program FITTED, we have designed a series of constrained covalent inhibitors, built from a series of bicyclic scaffolds, to study the optimal shape required for these small molecules. These structures bear nitrile functional groups that we predicted to covalently bind to the catalytic serine of the enzyme. Synthesis and biological assays using human brain-derived astrocytic cells and endothelial cells and human fibroblasts revealed that these compounds act as selective inhibitors of prolyl oligopeptidase activity compared to prolyl-dipeptidyl-aminopeptidase activity, are able to penetrate the cells and inhibit intracellular activities in intact living cells. This integrated computational and experimental study shed light oil the binding mode of inhibitors in the enzyme active site and will guide the design of future drug-like molecules.
