    Synthesis, cytotoxicity of new 4-arylidene curcumin analogues and their multi-functions in inhibition of both NF-κB and Akt signalling
    摘要:
    A series of new 4-arylidene curcumin analogues (4-arylidene-1,7-bisarylhepta-1,6-diene-3,5-diones) were synthesized and found to be potent antiproliferative agents against a panel of cancer cell lines at submicromolar to low micromolar concentrations by SRB assay. Their inhibitory abilities against NF-kappa B was evaluated by High Content Analysis (HCA) based immunofluorescence assay; and the Akt signalling inhibition was determined by fluorescence polarization assay and western blot respectively. The Structure Activity Relationship was discussed. Our results revealed that 4-arylidene curcumin analogues may work in a multi-targets manner in cancer cell. (C) 2012 Elsevier Masson SAS.

    公开号:US05510326A1
    公开(公告)日:1996-04-23
    Novel odorant compositions which are characterized by a content of one or more compounds selected from the group consisting of tetrahydrofurans of structures 1 or 2, or tetrahydropyrans of structure 3. ##STR1## wherein R can be an acyclic, where acyclic refers to a chain of at least four carbon atoms substituted with at least three methyl groups in the chain, carbocyclic, where carbocyclic refers to a ring of 5-8 carbon atoms, and with at least two methyl groups on the ring, or bicyclic where bicyclic refers to two carbon rings, each ring having between 5-8 carbon atoms fused together, substituted with at least two methyl groups, and where R.sub.1 .dbd.CH.sub.3, or higher alkyl group, R.sub.2 .dbd.H, CH.sub.3, or higher alkyl group, R.sub.3 .dbd.H, or CH.sub.3, R.sub.4 and R.sub.5 .dbd.H, CH.sub.3, or higher alkyl group.

  • 一种奈诺沙星螯合物的制备方法
    申请人:太景生物科技股份有限公司
    公开号:CN103159793B
    公开(公告)日:2016-08-03
    本发明公开了一种从奈诺沙星环合酯直接制备奈诺沙星螯合物的方法。现有方法中,反应步骤偏长、后处理过程偏多,导致制备奈诺沙星的整体时间明显延长;且不利于工业化生产及环保。本发明以羧酸酐或羧酸酐和羧酸的混合溶剂作为反应溶剂,加入硼酸或者硼酐反应;在得到的反应液中加入奈诺沙星环合酯,进行螯合反应,得到奈诺沙星螯合物。本发明的制备方法仅有一步螯合反应,减少了水解反应的过程及其过滤、干燥等复杂的后处理操作,使制备奈诺沙星的整体时间大大缩短,有利于工业化生产;同时又避免了浓盐酸、乙醇等试剂的使用,经济环保。
  • Process for the preparation of quinizarin
    申请人:Bayer Aktiengesellschaft
    公开号:US04387054A1
    公开(公告)日:1983-06-07
    A process, which does not pollute the environment, for the preparation of quinizarin consists in reacting a mixture of phthalic anhydride p-chlorophenol, sulphuric acid and boric acid or boric anhydride at elevated temperatures in such a way that, in the reaction mixture, there is sulphuric acid preferably containing 10-20% of free SO.sub.3 and the weight ratio of p-chlorophenol to the total amount of H.sub.2 SO.sub.4 +SO.sub.3 is 1:1.5 to 4.0. Yields and purity of the product are outstanding, despite the concentrated procedure.
    一种不污染环境的制备奎尼查林的过程包括在高温下反应邻苯二甲酸酐、对氯苯酚、硫酸和硼酸或硼酸酐的混合物,使得在反应混合物中,硫酸最好含有10-20%的游离SO.sub.3,并且对氯苯酚与总H.sub.2 SO.sub.4 + SO.sub.3的重量比为1:1.5至4.0。尽管是浓缩的操作,产物的产率和纯度都非常出色。
