  Synthesis of fluorescent lactosylceramide stereoisomers

  摘要：

  The intracellular distribution of synthetic glycosphingolipids (GSLs) bearing a fluorophore can be monitored in living cells by fluorescence microscopy. We reported previously that variation in the length of the long-chain base and in the structure of the carbohydrate-containing polar head group of (2S,3R) (or D-erythro-)-beta-lactosylceramide (LacCer) did not alter the mechanism of endocytic uptake from the plasma membrane of various mammalian cell types [Singh, R.D., Puri, V., Valiyaveettil, J.T., Marks, D.L., Bittman, R., Pagano, R.E., 2003. Selective caveolin-l-dependent endocytosis of glycosphingolipids. Mol. Biol. Cell 14, 3254-3265]. To extend our examination of the molecular features in LacCer that are responsible for its uptake by the caveolar-requiring endocytic pathway, we have synthesized the three unnatural stereoisomers [(2R,3R)-, (2S,3S)-, and (2R,3S)] of dipyrromethene difluoride (BODIPY (TM))-LacCer. These analogues will be used to probe the role of stereochemistry in the long-chain base of LacCer in the mechanism of endocytic uptake. (c) 2006 Elsevier Ireland Ltd. All rights reserved.

• Concise Synthesis of the Unnatural Sphingosine and Psychosine Enantiomer
  作者：Archana R. Parameswar、Jacqueline A. Hawkins、Laurel K. Mydock、Mark S. Sands、Alexei V. Demchenko

  DOI：10.1002/ejoc.201000024

  accumulation of psychosine (galactosyl sphingosine) has been associated with the pathogenesis of Krabbe disease, however, the exact mechanism of its cytotoxicity remains unclear. Herein, we describe the synthesis of the unnatural enantiomer of erythrosphingosine, psychosine, and related derivatives thereof that would allow for the mechanistic elucidation of the toxicity of psychosine.

  日期：2001.1

  The pyrene and nitrobenzoxadiazole (NBD) labeled derivatives of the natural sialyl Lewis(X) glycosphingolipid 1 were chemically synthesized as targets for investigating microdomain formation in membranes. The fluorescent analogs 2 and 3 were prepared by replacing the natural amide-linked fatty acid with a fluorescent analog. (C) 2001 Elsevier Science Ltd. All rights reserved.
