A novel phosphatidylinositol manno-oligosaccharide (dPIM-8) from Gordonia sputi.
The deacylated phosphatidylinositol manno-oligosaccharides (dPIMs) from the glycosyl phosphatidylinositol (GPI) carbohydrate antigen anchor of Gordonia sputi were the known 2,6-di-O-alpha-mannopyranosyl-myo-inositol glycerophosphate (dPIM-2) and the illustrated novel compound (dPIM-8), which could not be separated from dPIM-7 and dPIM-6, these three compounds being present in the mixture in the molar ratios 1.0:0.65:0.4. dPIM-8 is an analogue of dPIM-2 (and also of dPIM-7 and dPIM-6) in having alpha-mannopyranose and an alpha-mannopyranosyl linked heptasaccharide bonded to O-2 and O-6, respectively, of the inositol. The dPIM-8 species has not been found previously. [structure: see text]
