Synthetic studies on glycosphingolipids from Protostomia phyla: syntheses and biological activities of amphoteric glycolipids containing a phosphocholine residue from the earthworm Pheretima hilgendorfi.
Two types of amphoteric glycosphingolipid found in the earthworm Pheretima hilgendorfi, PC(-->6)-beta-d-Galp-(1-->6)-beta-d-Galp-(1-->1)Cer (1) and PC(-->6)-beta-d-Galp-(1-->6)-beta-d-Galp-(1-->6)-beta-d-Galp-(1-->1)Cer (2), and their derivatives (4, 5) were synthesized. These were examined for their ability to enhance production of interleukin-8 (IL-8), a potent inflammatory cytokine involved in neutrophil chemotaxis, in a TNFalpha-stimulated granulocytic HL-60 cells. Compounds 1 and 2 were found to be potent enhancers of IL-8 production.
