    A series of meta-substituted anilines were designed and synthesized to inhibit the interaction of LFA-1 with ICAM for the treatment of autoimmune disease. Design of these molecules was performed by utilizing a co-crystal structure for structure-based drug design. The resulting molecules were found to be potent and to possess favorable pharmaceutical properties.
