A-205804 is a potent and selective inhibitor of E-selectin and ICAM-1 with IC50 value of 20 nM and 25 nM, respectively .
E-selectin is a cell adhesion molecule and plays an important role in recruiting leukocytes to injury site during inflammation process. ICAM-1 (intracellular adhesion molecule 1) is a ligand for LFA-1 and involves in leukocytes binding to endothelial cells process. It has been reported that abnormal expression of E-selectin and ICAM-1 are correlated with a variety of cancers .
A-205804 is a selective E-selectin and ICAM-1 inhibitor over VCAM-1. When tested with primary HUVECs cells, A-205804 treatment reduced cell migration ability by inhibiting the expression of E-selectin and ICAM-1 . In human vascular endothelial cells using whole-cell high-throughput assay, it was shown that A-205804 exhibited potent and selective inhibition to E-selectin and ICAM-1 with low concentrations . Further, it was revealed that A-205804 inhibited E-selectin and ICAM-1 expressions by translocating to cell nucleus and noncovalently associated with macromolecules of molecular weight greater than 650 kDa when tested with human umbilical vein endothelial cells (HUVECs) .
