  摘要：

  提出了一种有效的一步合成新的功能化的苯并[ b ] [1,8]萘啶衍生物的策略。苯并[ g ] [1,8]萘啶是通过将取代的2-氯喹啉-3-甲醛与各种2-氯喹啉-4-胺，1 H-吲唑-6-胺在碱性介质中缩合而合成的。一系列苯并[ g ] [1,8]萘啶5（a–d），6（a–d）和2-氯喹啉-4-胺3（a–f）的电致发光和光物理性质为了获得良好的荧光材料而进行了报道和研究。此外，已经研究了电子给体-受体取代基对所有分子的荧光性质的影响以及它们的荧光量子产率。此外，我们通过密度泛函（DFT M06-HF）研究分析了与HOMO-LUMO相关的带隙能量。实验观察与理论计算非常吻合。所有合成的化合物均根据其NMR，质谱数据分析进行鉴定。

  Regioselective Azidation of 2,4-Dichloroquinolines

  摘要：

  Reactions of 2,4-dichloroquinolines (2a-f) with sodium azide in DMF lead either regioselectively to 4-azido-2-chloroquinolines (3a-f) or with excess of sodium azide and catalysts to 5-azido-tetrazolo[1,5-a]quinolines (4a-f). 2,4-Dichloroquinolines (2g-i) having electron donating substituents in 3-position react with sodium azide in DMF to a mixture of 4-azido-2-chloroquinolines (3g-i) and 5-chloro-tetrazolo[1,5-a]quinolines (5g-i). When the reaction of the 2,4-dichloroquinolines (2a-i) with sodium azide is carried out in ethanol with addition of methanesulfonic acid, regioselectively 5-chloro-tetrazolo[1,5-a]quinolines (5a-i) are obtained. Structural assignments of 3 and 5 have been carried out by C-13-NMR spectra, IR spectra and degradation reactions of the azido- and tetrazolo group to aminoquinolines (7 and 10) via iminophosphoranes (8 and 9). It could be shown that in 2-azido/tetrazolo-quinolines (4 and 5) the tetrazole ring structure is the dominant species.

  The insulin-like growth factor receptor (IGF-1R) is a receptor tyrosine kinase (RTK) involved in all stages of the development and propagation of breast and other cancers. The inhibition of IGF-1R by small molecules remains a promising strategy to treat cancer. Herein, we explore SAR around previously characterized lead compound (1), which is an aryl-heteroaryl urea (AHU) consisting of 4-aminoquinaldine and a substituted aromatic ring system. A library of novel AHU compounds was prepared based on derivatives of the 4-aminoquinoline heterocycle (including various 2-substituted derivatives, and naphthyridines). The compounds were screened for in vitro inhibitory activity against IGF-1R, and several compounds with improved activity (3-5 mu M) were identified. Furthermore, a computational docking study was performed, which identifies a fairly consistent lowest energy mode of binding for the more-active set of inhibitors in this series, while the less-active inhibitors do not adopt a consistent mode of binding.
