A 286982 is a selective inhibitor of LFA-1/ICAM-1 binding and LFA-1 with IC50 value of 44 nM and 35 nM, respectively .
Lymphocyte function-associated antigen-1 (LFA-1) is a member of leukocyte intergrins family and involves in T cells binding to antigen presenting cells. Intracellular adhension molecule-1 (ICAM-1) is a type of intercellular adhesion molecule and plays a pivotal role in cell-cell interactions. LFA-1/ICAM-1 interaction plays an important role in the pathogenesis of inflammatory disease .
A 286982 is a potent LFA-1/ICAM-1 inhibitor and has a different effect on the binding of compound 2B. When tested with LFA-1/ICAM-1 binding assay and LFA-1-mediated cellular adhesion assays, A-286982 treatment for 28h exhibited inhibition on LFA-1/ICAM-1interaction . Using the LFA-1/ICAM-1 ELISA assay, it was shown that A 286982 exhibited inhibition on the binding of ICAM-1-Ig to LFA-1 by reducing both ligands affinity and binding capacity .
