  Lipid A-Type Pyrancarboxylic Acid Derivatives, their Synthesis and their Biological Activities

  摘要：

  Synthesis of lipid A-type pyrancarboxylic acid derivatives, which have a carboxylic acid group in the anomeric position of the reducing sugar part of the disaccharide instead of the phosphoric acid group in lipid A, is described. We investigated the influence of the substituents in the 2'- and 6'-position of the molecules synthesized on their activities toward human monoblastic U937 cells. It was revealed that a series of compounds, possessing an acetamido group in the 2'-position showed strong LPS-antagonistic activity. (C) 2000 Elsevier Science Ltd. All rights reserved.

  Synthesis and biological activities of lipid A-type pyrancarboxylic acid derivatives

  摘要：

  The synthesis of lipid A-type pyrancarboxylic acid derivatives, which have a carboxylic acid group in the anomeric position of the reducing part of the disaccharide instead of the phosphate group in lipid A, is described. One of the compounds thus synthesized, which has an acyl substitution pattern similar to that of Escherichia coli lipid A, showed lipopolysaccharide (LPS)-agonistic activity. The other, which contains four lipid chains in the molecule, exhibited strong LPS-antagonistic activity toward human monoblastic U937 cells. (C) 2000 Elsevier Science Ltd. All rights reserved.
