  摘要：

  内脏利什曼病是一种被忽视的寄生虫病，在没有治疗的情况下死亡率很高。廉价，口服活性和有效的新药可能是对抗这种疾病的有用工具。我们以前表明，N 2，N 4-二取代的喹唑啉-2,4-二胺对细胞内利什曼原虫和铅化合物N 4-（呋喃-2-基甲基）-N 2-异丙基-7表现出低至亚微摩尔的效价。-甲基喹唑啉-2,4-二胺（4）在内脏利什曼病的急性小鼠模型中显示适度的功效。在本工作中，31 N 2，N评估了以前未检查过抗霉菌活性的4-二取代喹唑啉-2,4-二胺对内脏利什曼病的致病性寄生虫利什曼原虫的效力和选择性。在N 2和N 4处均具有芳族取代基的喹唑啉2,4-二胺显示出有效的体外抗菌活性，但选择性相对较低，而在N 2或N 4处被小烷基取代的化合物通常显示出较低的抗菌活性，但较少对鼠巨噬细胞系有毒。根据他们的体外抗农杆菌效力，N 4选择-苄基-N 2-（4-氯苄基）喹唑啉-2,4-二胺（15）和N 2-苄基-N

  continuous‐flow microfluidic setup enables in situ generation, extraction, separation, and reaction of foul‐smelling isocyanides with little exposure to the surroundings. Isocyanides were generated by dehydration of the corresponding N‐substituted formamides, and several representative isocyanide‐based organic reactions were successfully performed.

  日期：2014.8.1

  Given the importance of homogeneous catalysts recycling in organic chemistry, we have developed a unique microfluidic loop system for automated continuous recirculation of a soluble polymer supported metal catalyst for novel isocyanide cross-coupling reactions under thermomorphic multicomponent solvent (TMS) conditions. Our system provides an innovative approach for the chemical library synthesis of quinazolinone derivatives as well as an important intermediate of Merck's LTD4 antagonist "Singulair" with efficient continuous homogeneous catalyst recycling.
• Ligand-free palladium assisted insertion of isocyanides to urea derivatives for cascade synthesis of phenylamino-substituted quinazolinones
  作者：Siddharth Sharma、Abhilasha Jain

  DOI：10.1016/j.tetlet.2014.09.027

  日期：2014.10

  Palladium catalyzed cascade coupling of substituted urea derivatives and tert-butyl isocyanide for the efficient synthesis of phenylamino-substituted quinazolinones has been developed in moderate to good yields. This method provides a short and alternative approach for the synthesis of quinazolinones derivatives which are valuable compounds with biological and pharmacological potentials. A plausible mechanistic scheme is proposed. (C) 2014 Elsevier Ltd. All rights reserved.
• Design and synthesis of 2-(arylamino)-4(3H)-quinazolinones as novel inhibitors of rat lens aldose reductase
  作者：Jack DeRuiter、Abram N. Brubaker、Jane Millen、Thomas N. Riley

  DOI：10.1021/jm00155a007

  日期：1986.5

  A number of 2-(arylamino)-4(3H)-quinazolinones (2a-i) that possess several of the pharmacophore moieties necessary for binding to the inhibitor site of the enzyme aldose reductase were synthesized and tested for their ability to inhibit crude aldose reductase obtained from rat lens. Only those quinazolinones that possess an acidic moiety on the 2-(arylamino) substituent were found to display significant inhibitory activity. Of these, the most potent compound is the 4'-CO2H derivative (2i) with an IC50 of 34 microM, while the least potent is the 4'-OH derivative (2c) with an IC50 of 75 microM. All of the 2-(arylamino)-4(3H)-quinazolinones tested are less potent than other known inhibitors of aldose reductase, such as alrestatin and sorbinil, indicating that the pharmacophore moieties present in these compounds may not be positioned optimally relative to one another for maximal interaction with the enzyme.
