  Functionalized curcumin analogs as potent modulators of the Wnt/β-catenin signaling pathway

  摘要：

  Osteosarcoma is a primary bone malignancy with aggressive metastatic potential and poor prognosis rates. In our earlier work we have investigated the therapeutic potential of curcumin as an anti-invasive agent in osteosarcoma by its ability to regulate the Wnt/beta-catenin signaling pathway. However, the clinical use of curcumin is limited owing to its low potency and poor pharmacokinetic profile. In this study, an attempt was made to achieve more potent Wnt inhibitory activity in osteosarcoma cells by carrying out synthetic chemical modifications of curcumin. We synthesized a total of five series consisting of 43 curcumin analogs and screened in HEK293T cells for inhibition of beta-catenin transcriptional activity. Six promising analogs, which were 6.5- to 60-fold more potent than curcumin in inhibiting Wnt activity, were further assessed for their anti-invasive activity and Wnt inhibitory mechanisms. Western blot analysis showed disruption of beta-catenin protein nuclear translocation following treatment with analogs 2f, 3c and 4f. Using transwell assays, we also found that these compounds were more potent than la (curcumin) in impeding the invasion of osteosarcoma cells, possibly through suppressing MMP-9 activity. Structure-activity-relationship studies revealed that Wnt inhibitory effects could be enhanced by shortening and restraining the flexibility of the 7-carbon linker moiety connecting the terminal aromatic rings of curcumin and substituting both rings with appropriate substituents. Our results demonstrate that the synthesized curcumin analogs are more potent Wnt inhibitors in osteosarcoma cell lines as compared to parental curcumin and are good lead compounds for further development. Future in vivo tests with these compounds will define their therapeutic potentials as promising drug candidates for clinical treatment of osteosarcoma. (C) 2013 Elsevier Masson SAS.

  Curcumin is a plant diphenylheptanoid and has been investigated for its antibacterial activity. However, the therapeutic uses of this compound are limited due to its chemical instability. In this work, we evaluated the antimicrobial activity of diphenylheptanoids derived from curcumin against Gram-positive and Gram-negative bacteria, and also against Mycobacterium tuberculosis in terms of MIC (Minimum Inhibitory Concentration) and MBC (Minimum Bactericidal Concentration) values. 3,3'-Dihydroxycurcumin (DHC) displayed activity against Enterococcus faecalis, Staphylococcus aureus and M. tuberculosis, demonstrating MIC values of 78 and 156 mu g/mL. In addition, DHC was more stable than curcumin in acetate buffer (pH 5.0) and phosphate buffer (pH 7.4) for 24 h at 37 degrees C. We proposed that membrane and the cell division protein FtsZ could be the targets for DHC due to that fact that curcumin exhibits this mode of antibacterial action. Fluorescence microscopy of Bacillus subtilis stained with SYTO9 and propidium iodide fluorophores indicated that DHC has the ability to perturb the bacterial membrane. On the other hand, DHC showed a weak inhibition of the GTPase activity of B. subtilis FtsZ. Toxicity assay using human cells indicated that DHC has moderate capacity to reduce viability of liver cells (HepG2 line) and lung cells (MRC-5 and A549 lines) when compared with doxorubicin. Alkaline comet assay indicated that DHC was not able to induce DNA damage in A549 cell line. These results indicated that DHC is promising compound with antibacterial and antitubercular activities.
