Synthesis and biological activity of novel sialyl-lewisX conjugates

Abstract Novel sialyl Lewis X conjugates have been synthesized and evaluated as inhibitors of E- and P-selectin mediated cell adhesion in cell culture assays. The most potent conjugate in the static inhibition assays exhibited a significant and dose-dependent pharmacological potency as inhibitor of the edotoxin-induced leukocyte adhesion to the endothelium of postcapillary venules in rats.
