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