Abstract
Compounds which bind to selectin receptors and thus may modulate the course of inflammation, cancer and related processes by intervening with cell-cell adhesion events. Further, such compounds can be used for identification and analysis of such receptors. In this regard the invention is directed to compounds of formula (I). ##STR1## wherein R.sup.1 is independently H, alkyl, aryl, an aryl alkyl, alkenyl or one or more additional saccharide residues; R.sup.2 =H or OH provided that when R.sup.2 is H, R.sup.3 is OH; R.sup.3 =H or OH provided that when R.sup.3 is H, R.sup.2 is OH; X=H, SO.sub.3.sup.- or PO.sub.4.sup.- ; Y is independently H, OH, OR.sup.4 or NHCOR.sup.4, wherein R.sup.4 is alkyl, and Z is an organic acid residue. .alpha.-L-Fucose residue can be modified or replaced with suitable bioisosters or a different saccharide residue such as D-mannose. Modification of L-fucose may include replacement of each or all of the hydroxyl groups with H or OR' wherein R' can be methyl, ethyl or allyl groups.
