Histone deacetylases (HDACs) are important modulators of epigenetic gene regulation and additionally control the activity of non-histone protein substrates. While for HDACs 1-3 and 6 many potent selective inhibitors have been obtained, for other subtypes much less is known on selective inhibitors and the consequences of their inhibition. The present report describes the development of substituted benzhydroxamic acids as potent and selective HDAC8 inhibitors. Docking studies using available crystal structures have been used for structure-based optimization of this series of compounds. Within this study, we have investigated the role of HDAC8 in the proliferation of cancer cells and optimized hits for potency and selectivity, both in vitro and in cell culture. The combination of structure-based design, synthesis, and in vitro screening to cellular testing resulted in potent and selective HDAC8 inhibitors that showed anti-neuroblastoma activity in cellular testing.

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.
