Butein is a plant polyphenol, tetrahydroxychalcone that inhibits nuclear factor (NF)-κB (Yang et al; Pandey et al. 2007). Butein has been shown to prevent phosphorylation and degradation of TNF-dependent IκBα, an inhibitory subunit of NF-κB (IC₅₀ = 38 μM; Orlikova et al.). Butein also inhibits 5-lipoxygenase (IC₅₀ = 0.01 μM; Sogawa et al.), the enoyl-acyl-carrier protein reductase of Plasmodium falciparum (Ki = 2.97 μM; Sharma et al.), angiotensin-converting enzyme (IC₅₀ = 0.73 mM; Bonesi et al.), and SRC kinase (Pandey et al. 2009).

Natural chalcones as dual inhibitors of HDACs and NF-κB. Oncology reports 2012 SEP
Abstract
Histone deacetylase enzymes (HDACs) are emerging as a promising biological target for cancer and inflammation. Using a fluorescence assay, we tested the in vitro HDAC inhibitory activity of twenty-one natural chalcones, a widespread group of natural products with well-known anti-inflammatory and antitumor effects. Since HDACs regulate the expression of the transcription factor NF-κB, we also evaluated the inhibitory potential of the compounds on NF-κB activation. Only four chalcones, isoliquiritigenin (no. 10), butein (no. 12), homobutein (no. 15) and the glycoside marein (no. 21) showed HDAC inhibitory activity with IC50 values of 60-190 µM, whereas a number of compounds inhibited TNFα-induced NF-κB activation with IC50 values in the range of 8-41 µM. Interestingly, three chalcones (nos. 10, 12 and 15) inhibited both TNFα-induced NF-κB activity and total HDAC activity of classes I, II and IV. Molecular modeling and docking studies were performed to shed light into dual activity and to draw structure-activity relationships among chalcones (nos. 1-21). To the best of our knowledge this is the first study that provides evidence for HDACs as potential drug targets for natural chalcones. The dual inhibitory potential of the selected chalcones on NF-κB and HDACs was investigated for the first time. This study demonstrates that chalcones can serve as lead compounds in the development of dual inhibitors against both targets in the treatment of inflammation and cancer.

The synthesis and angiotensin converting enzyme (ACE) inhibitory activity of chalcones and their pyrazole derivatives. Bioorganic & medicinal chemistry letters 2010 MAR
Abstract
A series of chalcones (1-9) and pyrazoles (10-18) was prepared to investigate their potential activity as Angiotensin I-Converting Enzyme (ACE) inhibitors. Their structures were verified by elemental analysis, UV, IR, MS, (1)H NMR, (13)C NMR, and 2D NMR experiments. Among tested compounds, chalcone 7 exerted the highest activity with an IC(50) value of 0.219 mM, while the most potent pyrazole was 15 (IC(50) value of 0.213 mM).
