  Synthesis and biological properties of Pachastrissamine (jaspine B) and diastereoisomeric jaspines

  摘要：

  The synthesis of isomeric jaspines (anhydro phytosphingosines), arising from intramolecular cyclization of the corresponding phytosphingosines with different con. gurations at C3 and C4 positions of the sphingoid backbone, is reported. Natural jaspine B is the most cytotoxic isomer on A549 cells and it induces cell death in a dose-dependent manner. The cytotoxicity of jaspine B has been correlated with a significant increase of intracellular dihydroceramides, which seem to play an active role in autophagy. (c) 2008 Elsevier Ltd.

  effort to understand the structure–activity relationships, we have carried out syntheses of 26 new KRN7000 analogues incorporating aromatic residues in either or both side chains. Structural variations of the phytosphingosine moiety also include varying stereochemistry at C3 and C4, and 4-deoxy and 3,4-dideoxy versions. Their biological activities are described.

  日期：——

  A library of 64 phytosphingolipid analogues resulting from the systematic variation of the C1, C3, C4, and the N-acyl moiety of phytosphingosine (PHS) has been prepared from common scaffolds derived from the chiral pool and Sharpless asymmetric dihydroxylation reactions. Library members have been evaluated as growth inhibitors of the yeast Saccaromyces cerevisiae. In addition, 1-amino-N-pivaloyl PHS analogues were also tested as IPC synthase inhibitors, in comparison with the natural product khafrefungin.

• Stereoselective Divergent Synthesis of Four Diastereomers of Pachastrissamine (Jaspine B)

  A divergent short synthesis of four diastereomers of pachastrissamine was achieved. Natural pachastrissamine was synthesized through bis-tosylation of the common intermediate and cyclization. 2-epi-Pachastrissamine was obtained by monotosylation and spontaneous cyclization of D-ribo-phytosphingosine derivative. By use of regio- and stereospecific ring-opening reaction of the orthoester assisted by a Bee group as a key step, 3-epi- and 2,3-epi-pachastrissamines were synthesized. The three stereogenic centers of all the diastereomers were constructed by using Garner's aldehyde as the sole chiral source.
