  Antitumor agents 287. Substituted 4-amino-2H-pyran-2-one (APO) analogs reveal a new scaffold from neo-tanshinlactone with in vitro anticancer activity

  摘要：

  4-Amino-2H-benzo[h] chromen-2-one (ABO) and 4-amino-7,8,9,10-tetrahydro-2H-benzo[h] chromen-2-one (ATBO) analogs were found to be significant in vitro anticancer agents in our previous research. Our continuing study has now discovered a new simplified (monocyclic rather than tricyclic) class of cytotoxic agents, 4-amino-2H-pyran-2-one (APO) analogs. By incorporating various substituents on the pyranone ring, we have established preliminary structure-activity relationships (SAR). Analogs 19, 20, 23, and 26-30 displayed significant tumor cell growth inhibitory activity in vitro. The most active compound 27 exhibited ED50 values of 0.059-0.090 mu M. (C) 2011 Elsevier Ltd.

  product by an aromatic ring. This design element is general and the synthesis is straightforward, providing ready access to libraries of polyfunctional fluorophores with long Stokes shifts based on the epicocconone core. Our structural modifications resulted in analogues with increased photostability and quantum yields compared with the natural product. Staining proteomic gels with these new analogues

  Epicocconone 是一种天然的潜在荧光团，由于其较大的斯托克斯位移和在未结合状态下缺乏荧光而广泛用于生物技术。然而，epicocconone 的低光稳定性和量子产率限制了其更广泛的应用，并且在没有全合成的情况下，这种限制一直是一个长期存在的问题。在这里，我们报告了一种合成 Epiocconone 类似物的一般策略，该策略依赖于 2-碘氧基苯甲酸介导的脱芳构化和用芳香环替换天然产物的三烯尾。这种设计元素是通用的，合成很简单，可以随时访问基于epicocconone 核心的具有长斯托克斯位移的多功能荧光团库。与天然产物相比，我们的结构修改导致类似物具有更高的光稳定性和量子产率。用这些新类似物对蛋白质组凝胶染色显示检测限显着降低，检测到的低丰度蛋白质数量增加了 30%。这些epiccoconone 类似物将大大提高蛋白质组大海捞针中生物标志物针的发现率。

  The first Pd-catalyzed carbonylative couplings of aryl and vinyl halides with vinylogous enolates are reported generating products derived from C-C bond formation exclusively at the γ-position. Good results were obtained with a dienolate derivative of acetoacetate (1,3-dioxin-4-one). These transformations occurred at room temperature and importantly with only stoichiometric carbon monoxide in a two-chamber

  据报道，第一个 Pd 催化的芳基和乙烯基卤化物与乙烯基烯醇化物的羰基化偶联产生了仅在 γ 位形成 CC 键的产物。使用乙酰乙酸酯的二烯醇衍生物 (1,3-dioxin-4-one) 获得了良好的结果。这些转变发生在室温下，重要的是在两室反应器中仅使用化学计量的一氧化碳。该方法用于合成他汀类的两个成员，通过 γ-选择性羰基化和顺式立体选择性还原 3,5-二羰基酸中间体生成顺式 3,5-二醇酸基序。

  A variety of 2,2-dimethyl-6-(2-oxoalkyl)-1,3-dioxin-4-ones 5a-l and the corresponding 6-substituted 4-hydroxy-2-pyrones 3a-l were prepared in high yields under mild reaction conditions by the reaction of 2,2,6-trimethyl-1,3-dioxin-4-one 4 with 1-acylbenzotriazoles 9 in the presence of LDA followed by thermal cyclization of 5a-l to 3a-1. Synthesis of novel 6-(1-benzoylalkyl)-2,2-dimethyl-1,3-dioxin-4-ones 12a-c was achieved by alkylation of dioxinone 5a and their subsequent cyclization gave 5-alkyl-4-hydroxy-2-pyrones 13a-c.
