Synthesis and Identification of New 4-Arylidene Curcumin Analogues as Potential Anticancer Agents Targeting Nuclear Factor-κB Signaling Pathway
摘要:
A series of curcumin analogues including new 4-arylidene curcumin analogues (4-arylidene-1,7-bisarylhepta-1,6-diene-3,5-diones) were synthesized. Cell growth inhibition assays revealed that most 4-arylidene curcumin analogues can effectively decrease the growth of a panel of lung cancer cells at submicromolar and low micromolar concentrations. High content analysis technology coupled with biochemical studies showed that this new class of 4-arylidene curcumin analogues exhibits significantly improved NF-kappa B inhibition activity over the parent compound curcumin, at least in part by inhibiting I kappa B phosphorylation and degradation via IKK blockage; selected 4-arylidene curcumin analogues also reduced the tumorigenic potential of cancer cells in a clonogenic assay.
Series of curcumin derivatives were synthesized; the inhibitory activities on thioredoxin reductase (TrxR) of all analogues were evaluated by DTNB assay in vitro. It is found that most of the analogues can inhibit TrxR in the low micromolar range; Structure-activity relationship analysis reveals that analogues with furan moiety have excellent inhibitory effect on TrxR in an irreversible manner, indicating that the furan moiety may serve as a possible pharmacophore during the interaction of curcumin analogues with TrxR. The effect of selected curcuminoids on growth of different TrxR overexpressed cancer cell lines was also investigated and discussed. (C) 2008 Elsevier Ltd. All rights reserved.
