Synthesis and Biological Activity of 3,7-Anhydro-2,4-dideoxy-4-[(R)-3-hydroxytetradecanoylamino]-6-O-phosphono-5-O-[(R)-3-(tetradecanoyloxy)tetradecanoyl]-D-glycero-D-ido-octonic Acid Derivatives

摘要

D-Glucosaminylacetic acid derivatives (10, 11 and 12) of GLA-60 were synthesized to investigate the LPS-antagonistic activity toward human monoblastic U937 cells. Compounds 10 and 11 show weak LPS-antagonistic activity, but 12 shows both LPS-antagonistic and -agonistic activities, depending on the concentration.
