• Functionalized aurones as inducers of NAD(P)H:quinone oxidoreductase 1 that activate AhR/XRE and Nrf2/ARE signaling pathways: Synthesis, evaluation and SAR

  The chemopreventive potential of functionalized aurones and related compounds as inducers of NAD(P) H:quinone oxidoreductase 1 (NQO1, EC 1.6.99.2) are described. Several 4,6-dimethoxy and 5-hydroxyaurones induced NQO1 activity of Hepa1c1c7 cells by 2-fold at submicromolar concentrations, making these the most potent inducers to be identified from this class. Mechanistically, induction of NQO1 was mediated by the activation of AhR/XRE and Nrf2/ARE pathways, indicating that aurones may be mixed activators of NQO1 induction or agents capable of exploiting the proposed cross-talk between the AhR and Nrf2 gene batteries. QSAR analysis by partial least squares projection to latent structures (PLS) identified size parameters, in particular those associated with non-polar surface areas, as an important determinant of induction activity. These were largely determined by the substitution on rings A and B. A stereoelectronic role for the exocyclic double bond as reflected in the E-LUMO term was also identified. The electrophilicity of the double bond or its effect on the conformation of the target compound are possible key features for induction activity. (c) 2010 Elsevier Masson SAS. All rights reserved.
• Discovery and structure-activity relationship studies of 2-benzylidene-2,3-dihydro-1H-inden-1-one and benzofuran-3(2H)-one derivatives as a novel class of potential therapeutics for inflammatory bowel disease

  To develop effective therapeutics for inflammatory bowel disease (IBD), 2-benzylidene-2,3-dihydro-1-Hinden-1-one and benzofuran-3(2H)-one derivatives, were designed and synthesized and their structure activity relationships (SAR) were investigated. Compounds 7, 25, 26, 32, 39, 41, 52, 54, and 55 showed potent inhibitory effect (>70%) on the TNF-alpha-induced adhesion of monocytes to colon epithelial cells, which is one of the hallmark events leading to IBD. Such inhibitory activity of the compounds correlated with their suppressive activities against the TNF-alpha-induced production of ROS; ICAM-1 and MCP-1 expression, critical molecules involved in monocyte-epithelial adhesion; and NF-kappa B transcriptional activity. In addition, compounds 41 and 55 significantly suppressed the lipopolysaccharide (LPS)-induced expression of the TNF-alpha gene, with compound 55 showing better efficacy. This inhibition of TNF-alpha expression by compounds 41 and 55 corresponded to their additional inhibitory activity against AP-1 transcriptional activity, which is another transcription factor required for high level TNF-alpha expression. The strong inhibitory activity of compound 55 against an in vivo colitis model was confirmed by its dose dependent inhibitory activity in a rat model of 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitis, demonstrating compound 55 as a new potential candidate for the development of therapeutics against IBD.
