  Identification of novel and potent isoquinoline aminooxazole-Based IMPDH inhibitors

  摘要：

  Screening of our in-house compound collection led to the discovery of 5-bromo-6-amino-2-isoquinoline I as a weak inhibitor of IMPDH. Subsequent optimization of 1 afforded a series of novel 2-isoquinolinoaminooxazole-based inhibitors, represented by 17, with single-digit nanomolar potency against the enzyme.

  A microwave improvement in the synthesis of the quinazoline scaffold

  摘要：

  A rapid and efficient microwave-assisted protocol is described that greatly improves a recent synthetic method developed for quinazoline synthesis. The synthetic protocol is based on the use of cycles of microwave irradiation. The optimization process is reported and the experimental results are compared with those of the conventional synthetic route. (c) 2007 Elsevier Ltd. All rights reserved.

  日期：2006.12

  A new synthetic pathway to quinazolines is described. This new method uses hexamethylenetetramine in TFA and potassium ferricyanide in aqueous ethanolic KOH, starting from simple N-protected anilines. The method affords substituted quinazolines with high selectivities and good yields, reducing reaction-time and work-up operations.

  描述了一种合成喹唑啉的新途径。该新方法从简单的N保护苯胺开始，在TFA中使用六亚甲基四胺，在含水乙醇KOH中使用铁氰化钾。该方法提供了具有高选择性和良好收率的取代的喹唑啉，减少了反应时间和后处理操作。

  (IC50 33 μM). Optimization of hit 3 by SAR studies guided by SBDD identified indazole 38 (IC50 0.032 μM) and isoquinoline 45 (IC50 0.085 μM) as potent inhibitors of NOTUM. The binding of 45 to NOTUM was rationalized through an X-ray co-crystal structure determination which showed a flipped binding orientation compared to 3. However, it was not possible to combine NOTUM inhibition activity with metabolic

  NOTUM 是一种羧酸酯酶，已被证明通过介导 Wnt 蛋白的O-去棕榈油酰化而发挥作用，从而抑制 Wnt 信号传导。在这里，我们描述了 NOTUM 抑制剂的开发，该抑制剂可恢复 Wnt 信号传导，用于在NOTUM 过度活动是潜在原因的体外疾病模型中。用 NOTUM 进行的晶体片段筛选确定 2-苯氧基乙酰胺3与棕榈油酸袋结合，具有适度的抑制活性 (IC 50 33 μM)。由 SBDD 指导的 SAR 研究优化命中3确定了吲唑38 (IC 50 0.032 μM) 和异喹啉45 (IC 500.085 μM) 作为 NOTUM 的有效抑制剂。通过 X 射线共晶体结构测定使45与 NOTUM的结合合理化，该测定显示与3相比翻转的结合方向。然而，不可能将 NOTUM 抑制活性与代谢稳定性结合起来，因为大多数测试的化合物以 NADPH 非依赖性方式快速代谢。
