  3,5-双（2-氟苄叉）-4-哌啶酮诱导活性氧介导的A549细胞凋亡

  摘要：

  芳环的邻位上存在取代基有助于增强生物活性，从而突出了所谓的邻位效应。在本文中，我们合成了六个带有氟基团的单羰基姜黄素类似物，这些类似物赋予某些药物多种特性。然后，通过MTT分析评估针对A549和NCI-H460细胞的细胞毒性。结果表明，相对于姜黄素对A549细胞而言，1d表面上是一种重要的先导化合物，显示出几乎13倍的细胞毒性。更重要的是1d姜黄素比姜黄素更稳定，吸收更大，这可能与其姜黄素的细胞毒性，凋亡活性和活性氧的产生有关。活性氧的产生与氧化还原缓冲系统中的崩解有关，并随后引起脂质过氧化，线粒体膜电位的崩溃并最终导致细胞凋亡。这些数据表明邻位作用和将氟引入药物分子是提高单羰基姜黄素类似物的抗癌活性的成功策略。

  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.

  Fibroblast growth factor receptor 1 (FGFR1) is considered a therapeutic target for multiple cancers, including gastric cancer. FGFR1 inhibitors, being ATP competitors, can prevent the kinase domain and the downstream signaling cascade from phosphorylation and thus have the potential to treat cancers associated with aberrant FGFR1 activation. However, untargeted inhibition may cause numerous side effects

  成纤维细胞生长因子受体1（FGFR1）被认为是多种癌症（包括胃癌）的治疗靶标。作为ATP竞争者的FGFR1抑制剂可以防止激酶结构域和下游信号传导级联的磷酸化，因此具有治疗与异常FGFR1激活相关的癌症的潜力。但是，无针对性的抑制可能会导致许多副作用。因此，应紧急鉴定和探索非ATP竞争性FGFR1抑制剂。在这项研究中，我们设计并合成了17种去甲二氢愈创木酸（NDGA）衍生物，这是一种已知的非ATP依赖性FGFR3抑制剂。在激酶活性测定中，3,5-双（2-氟亚苄基）哌啶-4-酮（1B）在所有衍生物中显示出最高的激酶抑制活性，因此被鉴定为非ATP竞争性FGFR1抑制剂。在生物学效应评估中，1B以剂量依赖的方式抑制了FGFR-FRS2-ERK信号通路，并抑制了两种胃癌细胞的生长。总的来说，1B可被视为治疗胃癌的潜在候选药物，并且是发现新型非ATP竞争性FGFR1抑制剂的杰出先导化合物。

  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.

  almost 13-fold cytotoxicity relative to curcumin against A549 cells. More importantly, 1d was more stable and more massive uptake than curcumin, which may be relationship to their cytotoxicity, apoptotic acitivity and reactive oxygen species generation. The generation of reactive oxygen species is associated with falling apart in the redox buffering system, and subsequently induces lipid peroxidation
