摘要
Several fucodipeptides and their liposome-like derivatives were prepared and tested as inhibitors of sialyl Lewis X binding to E-selectin. It has been found that trans-hydroxyproline (D or L) can be used to mimic the galactose residue of sialyl Lewis X, and the mimetic containing 3,4-dihydroxy-D-proline is the most active with IC50 value (50 mu M) 10-fold greater than sialyl Lewis X. Derivatization of a hydroxythreonine-containing fucodipeptides into a covalent liposome-like derivative, however, provides a mimetic with only IC50 similar to 30 mu M.
