  Heck cross-coupling reaction of 3-iodoindazoles with methyl acrylate: a mild and flexible strategy to design 2-aza tryptamines

  摘要：

  In order to design 2-azabioisosteres of tryptamine, serotonin or melatonin, the conditions of the Heck coupling reaction of 3-iodoindazoles with methyl acrylate are studied. This reaction authorizes the synthesis of 3-indazolylpropenoates as key intermediates to prepare 3-indazolylpropionic acids and 3-indazolylethyl-amines. The flexible synthetic strategy allows molecular diversity. (C) 2000 Elsevier Science Ltd. All rights reserved.

  未保护的3-碘吲唑与频哪醇乙烯基硼酸酯的Suzuki型交叉偶联反应：在微波辐射下吲唑的C-3乙烯基化。

  摘要：

  本文中，我们报告了微波辐射下未保护的3-碘吲唑的便捷C-3乙烯基化。通过这种方法合成了十种C-5取代的3-乙烯基吲唑衍生物，其中九种是新颖的，从C-5取代的3-碘吲唑衍生物开始，以中等至优异的产率进行。在所有情况下，C-3乙烯基化衍生物都是唯一的分离产物。这种方法可以选择性地和直接地获得3-乙烯基化的吲唑，而无需N-保护。3-乙烯基吲唑可能是有趣的合成中间体，可以接触生物活性分子。

• ML212: A small-molecule probe for investigating fluconazole resistance mechanisms in <i>Candida albicans</i>

  日期：——

  The National Institutes of Health Molecular Libraries and Probe Production Centers Network (NIH-MLPCN) screened >300,000 compounds to evaluate their ability to restore fluconazole susceptibility in resistant Candida albicans isolates. Additional counter screens were incorporated to remove substances inherently toxic to either mammalian or fungal cells. A substituted indazole possessing the desired bioactivity profile was selected for further development, and initial investigation of structure–activity relationships led to the discovery of ML212.

  国家卫生研究院分子图书馆和探针生产中心网络（NIH-MLPCN）筛选了超过300,000种化合物，以评估它们恢复对耐药念珠菌的氟康唑敏感性的能力。还加入了额外的对照筛选，以去除对哺乳动物或真菌细胞有毒的物质。选择了具有所需生物活性特征的取代吲唑化合物进行进一步开发，并初步研究结构-活性关系导致了ML212的发现。
