A 286982 is a potent inhibitor known for its ability to block the interaction between leukocyte function-associated antigen-1 (LFA-1) and intercellular adhesion molecule-1 (ICAM-1). It effectively inhibits this integrin-ligand interaction with a measured IC50 value of 35 nM. Furthermore, A 286982 demonstrates its inhibitory properties by significantly reducing the adhesion of JY-8 cells to ICAM-1-coated microtiter plates, with an IC50 value of 44 nM. Its specific role lies in obstructing the interaction between LFA-1 and ICAM-1, making A 286982 a promising inhibitor with potential applications in various contexts related to leukocyte function-associated antigen-1 and intercellular adhesion molecule-1.
