  Development of inhibitors to antagonize the activities of antiapoptotic Bcl-2 family proteins is of particular interest in cancer chemotherapy. We discovered a quinazoline-2(1H)-thione derivative (DCBL55) as a new Bcl-xL, Bcl-2, and Mcl-1 inhibitor by virtual database screening. We systematically modified the structure of compound 1 by chemical synthesis. The interactions of the compounds with Bcl-xL

  拮抗抗凋亡的Bcl-2家族蛋白活性的抑制剂的开发在癌症化学疗法中尤为重要。通过虚拟数据库筛选，我们发现了一种喹唑啉-2（1 H）-硫酮衍生物（DCBL55）作为新的Bcl-x L，Bcl-2和Mcl-1抑制剂。我们通过化学合成系统地修饰了化合物1的结构。通过分子模拟模拟预测了化合物与Bcl-x L的相互作用，并通过结构-活性关系分析和蛋白质突变研究证实了这一点。Bcl-x L疏水槽的三个位置发现被称为P2，P4和P5的P2，P4和P5有助于配体相互作用。尽管该化合物诱导线粒体电位降低，半胱天冬酶激活和ROS产生，但细胞毒性和线粒体外膜的超微结构变化表明该化合物可能靶向Bcl-2家族以外的其他蛋白质。总之，本研究提供了新的先导化合物和重要的结构信息，以进一步开发抗凋亡Bcl-2家族蛋白的更强效和特异性抑制剂。

  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 series of 43 curcumin diarylpentanoid analogues were synthesized and evaluated for their inhibitory effects on the chemiluminescence and chemotactic activity of phagocytes in vitro.

  The effects of the compounds on the respiratory burst of human whole blood and isolated human polymorphonuclear leukocytes (PMNs) were evaluated using a luminol-based chemiluminescence assay and their effect on chemotactic migration of PMNs was investigated using the Boyden chamber technique.

  Compounds 6, 17, 25 and 30 exhibited significant inhibitory activity on the oxidative burst of PMNs. The presence of methoxy groups at positions 2 and 5, and methoxylation and fluorination at positions 4 and 2 of both phenyl rings, respectively, may contribute significantly to their reactive oxygen species inhibition activity. Compounds 7, 17, 18, 24 and 32 showed strong inhibition of the chemotaxis migration of PMNs. Chlorination at various positions of both phenyl rings of cyclohexanone diarylpentanoid resulted in compounds with potent inhibitory effects on PMN migration.

  The results suggest that some of these diarylpentanoid analogues are able to modulate the innate immune response of phagocytes at different steps, emphasizing their potential as a source of new immunomodulatory agents.
