  Novel benzofuran-3-one indole inhibitors of PI3 kinase-α and the mammalian target of rapamycin: Hit to lead studies

  摘要：

  A series of benzofuran-3-one indole phosphatidylinositol-3-kinases (PI3K) inhibitors identified via HTS has been prepared. The optimized inhibitors possess single digit nanomolar activity against p110 alpha (PI3K-alpha), good pharmaceutical properties, selectivity versus p110 gamma (PI3K-gamma), and tunable selectivity versus the mammalian target of rapamycin ( mTOR). Modeling of compounds 9 and 32 in homology models of PI3K-alpha and mTOR supports the proposed rationale for selectivity. Compounds show activity in multiple cellular proliferation assays with signaling through the PI3K pathway confirmed via phospho-Akt inhibition in PC-3 cells. (C) 2010 Elsevier Ltd.

• The facile synthesis of 2-bromoindoles via Cs₂CO₃-promoted intramolecular cyclization of 2-(gem-dibromovinyl)anilines under transition-metal-free conditions
  作者：Pinhua Li、Yong Ji、Wei Chen、Xiuli Zhang、Lei Wang

  DOI：10.1039/c2ra22172a

  日期：——

  2-Bromoindoles were readily prepared through a facile Cs2CO3-promoted intramolecular cyclization of 2-(gem-bromovinyl)-N-methylsulfonylanilines in excellent yields under transition-metal-free conditions. This methodology could be extended to the synthesis of corresponding 2-chloroindoles. The reaction mechanism suggested that cyclization occurs through a key intermediate, phenylethynyl bromide, followed by cyclization in one-pot.
