Human 5-lipoxygenase (5-LOX) is a well-validated target for anti-inflammatory therapy. Development of novel 5-LOX inhibitors with higher activities is highly demanded. In previous study, we have built a model for the active conformation of human 5-LOX, and identified naphthalen-1-yl 3,5-dinitrobenzoate (JMC-4) as a 5-LOX inhibitor by virtual screening. In the present work, 3,5-dinitrobenzoate-based 5-lipoxygenase inhibitors were developed. Twenty aryl 3,5-dinitrobenzoates, N-aryl 3,5-dinitrobenzamides and analogues were designed and synthesized. Several of them were found with significantly increased activities according to cell-free assay and human whole blood assay. The structure-activity relationship study may provide useful insights for designing effective 5-LOX inhibitors. (C) 2014 Elsevier Ltd. All rights reserved.
