  The total synthesis of an aurone isolated from Uvaria hamiltonii : aurones and flavones as anticancer agents

  摘要：

  The naturally occurring aurone 1, isolated from Uvaria hamiltonii, and a series of aurones analogues based structurally on known tubulin binding agents were prepared and evaluated for anticancer activity. Aurone 20 was the most active (IC50 K562 50 nM) and caused significant G(2)/M cell-cycle arrest. (C) 2003 Elsevier Ltd. All rights reserved.

  Discrepancies in published work on the alkaline peroxide oxidation of chalcones (AFO reaction) have been examined. It has been found that in addition to flavonols and aurones, 2-benzyl-2-hydroxydihydrobenzofuran-3-ones (IX), and 2-arylbenzofuran-3-carboxylic acids (XV), each new as regards this reaction, appear in the products. A mechanism for the production of these latter compounds is suggested.

  已经检查了有关查尔酮的碱性过氧化物氧化（AFO反应）的已发表工作中的差异。已经发现，除了黄酮醇和金酮之外，在该反应中还出现了2-苄基-2-羟基二氢苯并呋喃-3-酮（IX）和2-芳基苯并呋喃-3-羧酸（XV）。产品。建议了产生这些后面的化合物的机理。
