  使用不含溶剂的取代基增强供体-受体分子的一般策略。

  摘要：

  尽管有机供体-受体（DA）分子广泛应用于多个领域，但由于固有的极性敏感性会抑制光化学过程，因此可能会限制更多DA分子的应用。本文介绍了一种简便的化学修饰方法，可通过添加基于β-羰基的极性取代基来减弱溶剂依赖的激发态猝灭机理。结果揭示了一种机制，其中β-羰基取代基在供体和周围溶剂之间产生结构缓冲。通过计算和实验分析，证明了β-羰基同时减弱了两种不同的溶剂依赖性猝灭机理。使用β-羰基取代基

• Lead optimization of novel p53-MDM2 interaction inhibitors possessing dihydroimidazothiazole scaffold

  With the aim of discovering potent inhibitors of the p53-MDM2 interaction and thus obtaining a potent anticancer drug, we have pursued synthesis and optimization of dihydroimidazothiazole derivatives, which have been discovered via scaffold hopping by mimicing the mode of interaction between MDM2 and Nutlins. Upon the discovery we encountered a problem involving the chemical instability of the scaffold, that is, susceptibility to oxidation which led to imidazothiazole. In order to solve this problem and to obtain further potent compounds, we executed medicinal research and thus furnished the optimal compounds by incorporating the methyl group onto the C-6 position to avoid the oxidation, and by modifying the C-2 moiety of the additional proline motif, which furnished high potency. The incorporation of the pyrrolidine moiety at the C-2 position raised another hydrophobic interaction site with MDM2 protein, which was generated by the induced-fitting observed by co-crystal structure analysis. These optimal molecules showed significant improvement in potency when compared with the early lead (+)-1 or Nutlin-3a. (c) 2012 Elsevier Ltd. All rights reserved.
