  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.

  A novel RhCl(PPh3)(3)/BF3 center dot OEt2 co-promoted direct C-C cross-coupling of primary and secondary alcohols at beta-position with aldehyde was developed. This reaction could provide an efficient synthesis of a series of alpha, beta-unsaturated aldehydes and diarylidene ketones, just from simple and easily available alcohols and aldehydes.

  Abstract An efficient methodological approach for the synthesis of a novel series of 4-aryl-8-arylidene-2-cyanoimino-1,2,3,4,5,6,7,8-octahydroquinazolines (aryl-CIOHQs) was presented via one-pot four-component reaction of cyclohexanone, two-folds of various aromatic aldehydes and cyanoguanidine in the presence of sodium ethoxide as basic catalyst. The same target products (aryl-CIOHQs) were also reproduced
