  Synthesis of functionalized cyclohexenephosphonates and their inhibitory activity towards bacterial sialidases

  摘要：

  We have synthesized a series of cyclohexenephosphonates derived from D- and L-xylose, designed as core structures for the development of high affinity mimics of sialic acid and of the sialidase reaction transition state, Extension of our syntheses to both xylose enantiomers has given us access to two series of cyclohexenephosphonates with regioisomeric double bonds. We have demonstrated the selective functionalization of the hydroxyl groups towards introduction of a glycerol side chain mimic and immobilization via a silyl linker. The inhibitory activity of a selected set of compounds towards three bacterial sialidases has been tested and moderate activity was found. (C) 2002 Elsevier Science Ltd. All rights reserved.

  CHIMERIC RNA WITH MODIFIED BACKBONES: ALTERNATING METHYLENE(METHYLIMINO) LINKED PHOSPHODIESTER BACKBONE OLIGONUCLEOTIDES WITH 2′-OH AND 2′-OMe GROUPS

  摘要：

  Synthesis of a novel ribo-MMI dimer with 2'-OH and 2'-OMe in 5'- and 3'-nucleosides, respectively is presented. The synthesis was accomplished by reductive coupling of 3'-deoxy-3'-C-formyluridine and 2'-O-methyl-5'-O-methylaminouridine via a thioacetal as the key intermediate for the top part of the dimer. Incorporation of ribo-MMI dimers into oligonucleotides increased binding affinity for target RNA.

  A stereoselective synthesis of 3'-deoxy-3'-C-formyl-5-methyluridine 2 is described via the dithiane 4 as the key intermediate. Compound 2 was coupled with 3 into a novel ribo-MMI dimer 1. The dimer was then incorporated into antisense oligonucleotides which were found to have high binding affinity to the target RNA. (C) 2000 Elsevier Science Ltd. All rights reserved.
