  3-Fluoroazetidinecarboxylic Acids and trans,trans-3,4-Difluoroproline as Peptide Scaffolds: Inhibition of Pancreatic Cancer Cell Growth by a Fluoroazetidine Iminosugar

  摘要：

  Reverse aldol opening tenders amides of 3-hydroxyazetidinecarboxylic acids (3-OH-Aze) unstable above pH 8. Axe, found in sugar beet, is mis-incorporated for proline in peptides in humans and is associated with multiple sclerosis and teratogenesis. Axe-containing peptides may be oxygenated by prolyl hydroxylases resulting in potential damage of the protein by a reverse aldol of the hydroxyazetidine; this, rather than changes in conformation; may account for the deleterious effects of Axe. This paper describes the synthesis of 3-fluoro-Aze amino acids as hydroxy-Aze analogues which are not susceptible to aldol cleavage. 4-(Azidomethyl)-3-fluoro-Aze and 3,4-difluoroproline are new peptide building blocks. trans,trans-2,4-dihydroxy-3-fluoroazetidine, an iminosugar, inhibits the growth of pancreatic cancer cells to a similar degree as gemcitabine.

  L-DMDP and L-homoDMDP, the enantiomers of naturally occurring DMDP and homoDMDP have been synthesized from D-xylose derived cyclic nitrone 9. Their 3-deoxy-3-fluorinated analogues were also obtained from polyhydroxylated fluorinated cyclic nitrone 10, which was prepared from fluorinated sugar 12 in seven steps. Bioactivities of these iminosugars against various glycosidases were evaluated. While L-DMDP and L-homoDMDP are potent inhibitors of α-glucosidases, a sharp decrease of inhibition was found when the C-3 hydroxyl group of these compounds was replaced by fluoride, which showed the great importance of the C-3 hydroxyl in their interaction with enzymes.

  L-DMDP和L-homoDMDP是天然存在的DMDP和homoDMDP的对映体，已通过从D-木糖衍生的环状亚硝酮9合成。它们的3-去氧-3-氟化类似物也通过从氟化糖12经过七步反应制备的多羟基氟化环状亚硝酮10获得。这些亚氨糖对多种糖苷酶的生物活性进行了评估。虽然L-DMDP和L-homoDMDP是α-葡萄糖苷酶的强抑制剂，但当这些化合物的C-3羟基被氟替代时，抑制作用明显下降，这显示了C-3羟基在与酶相互作用中的重要性。

  S-Ribosylhomocysteinase (LuxS) catalyzes the cleavage of the thioether bond of S-ribosylhomocysteine (SRH) to produce homocysteine and 4,5-dihydroxy-2,3-pentanedione (DPD), which is the precursor of type 2 autoinducer for bacterial cell-cell communication. In this work, we have synthesized several SRH analogues modi. ed at the ribose C3 position as potential inhibitors of LuxS. While removal or methylation of the C3-OH resulted in simple competitive inhibitors of moderate potency, inversion of the C3 stereochemistry or substitution of. uorine for C3-OH resulted in slow-binding inhibitors of improved potency. The most potent inhibitor showed a K*(I) value of 0.43 mu M. (C) 2009 Elsevier Ltd. All rights reserved.
