structure-activity profiles. The preparation of the hetero-disubstituted compounds (1b-e) was accomplished by a sequential introduction of different 3- and 4-aryl groups, obtained by exploiting the different reactivity of the bromineversuschlorinesubstituents on the precursor, 2-bromo-3-chloronitrobenzene (5), in the palladium-catalyzed cross-coupling reactions. The results of the biological tests show that the

601-fold selectivity over FABP3 when maintained nanomolar binding affinity for FABP4. Moreover, C3 also shows good metabolic stability and potent cellular anti-inflammatory activity, making it a promising inhibitor for further development. Therefore, the present study highlights the utility of the structure-based rational design strategy for seeking highly selective and potent inhibitors of FABP4 and
