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.
The invention provides for bifunctional molecules comprising an UchL5 binding partner and a target protein binding partner linked via a flexible linker. A bifunctional molecule according to the invention binds to UchL5 and to the target protein, thereby facilitating degradation of the target protein bound to the target protein binding partner. The invention also provides for use of a bifunctional molecule for preventing or treating disease.
