  Synthesis of novel heme-interacting acridone derivatives to prevent free heme-mediated protein oxidation and degradation

  摘要：

  Heme is an important prosthetic molecule for various hemoproteins and serves important function in living aerobic organisms. But degradation of hemoprotein, for example, hemoglobin during different pathological conditions leads to the release of heme, which is very toxic as it induces oxidative stress and inflammation due to its pro-oxidant nature. Thus, synthesis of compound that will detoxify free heme by interacting with it would be fruitful for the management of heme-induced pathogenesis. Here, we report the synthesis of a novel natural product arborinine and some other acridone derivatives, which interact with free heme. These acridones in vitro block heme-mediated protein oxidation and degradation, markers for heme-induced oxidative stress. (C) 2011 Elsevier Ltd. All rights reserved.

  monoamidation of aromatic ketones, chalcone, carbazole, and benzophenones was achieved by employing high‐valent cobalt and rhodium catalysis to access numerous biologically important molecular building blocks. This amidation proceeded smoothly with a variety of ketones and several amidating partners. The application of the products in the synthesis of various heterocycles, including acridones, indoles, quinoline

  芳香族酮，查尔酮，咔唑和二苯甲酮的弱配位，酮定向，区域选择性单酰胺化是通过使用高价钴和铑催化作用来获得许多生物学上重要的分子构件而实现的。该酰胺化反应与各种酮和一些酰胺化伙伴一起进行得很顺利。还研究了产物在各种杂环的合成中的应用，包括including啶，吲哚，喹啉，喹诺酮，喹啉酮和喹唑啉。通过这种方法，也可以完成基于cri啶酮的生物碱的总合成，即托达洛辛A，托达洛辛D和Arborinine，以及正式合成了丙烯醛和诺拉霉素。

  In order to develop an efficient, rapid, and modular cascade strategy for the direct synthesis of acridones, palladium supported on sulfated alumina and microwave activation are employed. Multifunctional heterogeneous palladium catalysts were prepared in order to carry out the sequential annulation via a Buchwald–Hartwig amination followed by an intramolecular annulation in a one-pot process. This
