Synthesis and Biological Activities of Analogs of a Lipid A Biosynthetic Precursor: 1-O-Phosphonooxyethyl-4'-O-phosphono-disaccharides with (R)-3-Hydroxytetradecanoyl or Tetradecanoyl Groups at Positions 2, 3, 2' and 3'.
Two novelanalogs of a biosynthetic precursor of lipid A (2) were synthesized. The one analog (3) has acyl groups identical to those of 2, and the other (4) has tetradecanoyl groups in place of the (R)-3-hydroxytetradecanoyl groups of 2. Both 3 and 4 possess an alpha-glycosidically-bound phosphonooxyethyl group in place of the alpha-glycosyl phosphate group of 2. Compounds 3 and 4 exhibited definite
