  Synthesis and preliminary evaluation of curcumin analogues as cytotoxic agents

  摘要：

  A series of curcumin analogues with different substituents at the 4-position of the phenyl group were synthesized and screened for in vitro cytotoxicity against a panel of human cancer cell lines. Several novel curcumin analogues, especially 32 and 34, exhibited selective and potent cytotoxic activity against human epidermoid carcinoma cell line A-431 and human glioblastoma cell line U-251, implying their specific potential in the chemoprevention and chemotherapy of skin cancer and glioma. The preliminary SAR information extracted from the results suggested that introduction of appropriate substituents to the 4'-positions could be a promising approach for the development of new cytotoxic curcumin analogues with special selectivity for A-431 and U-251 cell lines.

• Cation Radical Accelerated Nucleophilic Aromatic Substitution via Organic Photoredox Catalysis

  Nucleophilic aromatic substitution (SNAr) is a direct method for arene functionalization; however, it can be hampered by low reactivity of arene substrates and their availability. Herein we describe a cation radical-accelerated nucleophilic aromatic substitution using methoxy- and benzyloxy-groups as nucleofuges. In particular, lignin-derived aromatics containing guaiacol and veratrole motifs were

  亲核芳香取代（S Ñ AR）是芳烃官能化的直接法; 然而，芳烃底物的低反应性及其可用性可能会阻碍它的发展。在本文中，我们描述了使用甲氧基和苄氧基作为核熔剂的阳离子自由基加速的亲核芳族取代。特别是，含有愈创木酚和藜芦基序的木质素衍生的芳族化合物是功能化的有效底物。我们还证明了用三氟乙醇进行位点选择性取代氧合的例子，以提供所需的三氟甲基芳基醚。
