  Multidimensional optimization of promising antitumor xanthone derivatives

  摘要：

  A promising antitumor xanthone derivative was optimized following a multidimensional approach that involved the synthesis of 17 analogues, the study of their lipophilicity and solubility, and the evaluation of their growth inhibitory activity on four human tumor cell lines. A new synthetic route for the hit xanthone derivative was also developed and applied for the synthesis of its analogues. Among the used cell lines, the HL-60 showed to be in general more sensitive to the compounds tested, with the most potent compound having a GI(50) of 5.1 mu M, lower than the hit compound. Lipophilicity was evaluated by the partition coefficient (K-p) of a solute between buffer and two membrane models, namely liposomes and micelles. The compounds showed a log K-p between 3 and 5 and the two membrane models showed a good correlation (r(2) = 0.916) between each other. Studies concerning relationship between solubility and structure were developed for the hit compound and 5 of its analogues. (C) 2013 Elsevier Ltd. All rights reserved.

• Formation of Furan Derivatives from Phenacyl Bromides and Sodium Telluride; Attempted Extension to Coumarin Synthesis

  The enolates, generated from phenacyl bromides by sodium telluride, yield 2,4-diarylfurans in addition to the expected dehalogenation products. No 1,4-dicarbonyl compounds could be isolated even in the presence of excess oxidizing agent, copper(II) chloride. Condensation of 2-(methoxymethoxy)arenecarbaldehydes with ethyl bromoacetate in the presence of sodium telluride gave the expected α,β-unsaturated

  除了预期的脱卤产物外，由碲化钠从苯甲酰溴生成的烯醇化物还产生 2,4-二芳基呋喃。即使存在过量的氧化剂氯化铜 (II)，也无法分离出 1,4-二羰基化合物。在碲化钠存在下，2-(甲氧基甲氧基)芳烃甲醛与溴乙酸乙酯的缩合得到预期的α,β-不饱和酯，其抵抗环化以产生所需的香豆素衍生物。尝试进行 2-(溴乙酰氧基) 苯甲醛的分子内 Reformatsky 型反应，仅得到 6,12-环氧-6H,12H-二苯并[b,f]-[1,5] 二恶星作为主要产物。

  The first one‐pot synthesis of N‐substituted 2‐H‐4‐benzylidene imidazolones and their subsequent palladium‐catalyzed and copper‐assisted direct C2−H arylation and alkenylation with aryl‐ and alkenylhalides are described. This innovative synthesis is step‐economical, azide‐free, high yielding, highly flexible in the introduction of a variety of electronically different groups, and can be operated on
