  摘要：

  抑制VEGF信号传导途径已成为治疗癌症的有价值的方法。在这项工作中，设计了一系列N-（2-苯基-1 H-苯并[ d ]咪唑-5-基）喹啉-4-胺衍生物并将其鉴定为VEGFR-2（KDR）激酶的有效抑制剂。合成了具有喹啉骨架和苯并咪唑部分的这些化合物，并评估了它们对VEGFR-2和两种人类癌细胞系的生物学活性。其中，化合物7s对VEGFR-2的抑制作用最强，IC 50为0.03μM，对受试癌细胞系的IC 50表现出最高的抗癌活性。针对MCF-7为1.2μM，针对Hep-G2为13.3μM。对接模拟支持最初的药效学假说，并提出了在VEGFR-2 ATP结合位点的共同相互作用方式，这表明化合物7s是潜在的癌症治疗药物，值得进一步研究。

  α-diazo carbonyl compounds via C–H activation/carbene insertion/intramolecular cyclization is explored. The switchable product selectivity is achieved by the use of distinct α-diazo carbonyl compounds. Benzimidazole-fused quinolines are obtained through [4 + 2] annulation exclusively when 2-diazocyclohexane-1,3-diones are used, where they act as a C2 synthon. Alternatively, diazonaphthalen-1(2H)-ones

  探索了 Rh(III) 催化的 2-芳基苯并咪唑与 α-重氮羰基化合物通过 C-H 活化/卡宾插入/分子内环化的成环反应。可切换的产物选择性是通过使用不同的 α-重氮羰基化合物来实现的。仅当使用 2-重氮环己烷-1,3-二酮时，苯并咪唑稠合喹啉才通过 [4 + 2] 环化获得，其中它们充当 C2 合成子。或者，重氮萘-1(2 H )-酮仅充当一碳单元合成子，通过[4 + 1]环化产生季中心，得到螺环苯并咪唑稠合异吲哚萘-2-酮。彻底的机理研究揭示了反应过程。

  Both c-Met and VEGFR-2 are important targets for the treatment of cancers. In this study, a series of N-(2-phenyl-1H-benzo[d]imidazol-5-yl)quinazolin-4-amine derivatives were designed and identified as dual c-Met and VEGFR-2 inhibitors. Among these compounds bearing quinazoline and benzimidazole fragments, compound 7j exhibited the most potent inhibitory activity against c-Met and VEGFR-2 with IC50 of 0.05μM and 0.02μM, respectively. It also showed the highest anticancer activity against the tested cancer cell lines with IC50 of 1.5μM against MCF-7 and 8.7μM against Hep-G2. Docking simulation supported the initial pharmacophoric hypothesis and suggested a common mode of interaction at the ATP-binding site of c-Met and VEGFR-2, which demonstrates that compound 7j is a potential agent for cancer therapy deserving further researching.

  Here, we report the discovery of a new class of NPBWR1 antagonists identified from a fragment-based screen. Compound 1 (cAMP IC₅₀ = 250 µM; LE = 0.29) emerged as an initial hit. Further optimization of 1 by SAR-by-catalogue and chemical modification produced 21a (cAMP IC₅₀ = 30 nM; LE = 0.39) with a 6700-fold increase in potency from fragment 1. Somewhat surprisingly, Schild analysis of compound 21a suggested that in vitro inhibition of NPW-mediated effects on upon cAMP accumulation were saturable, and that compound 21a dose-dependently increased [125I]-hNPW23 dissociation rate constants from NPBWR1 in kinetic binding studies. Collectively, these data are inconsistent with a classic surmountable, orthosteric mechanism of inhibition. The benzimidazole inhibitors reported herein may therefore represent a mechanistically differentiated class of compounds with which to form a better appreciation of the pharmacology and physiological roles of this central neuropeptide system.

  ol-5-yl)quinolin-4-amine derivatives were designed and identified as potent inhibitors of VEGFR-2 (KDR) kinase. These compounds with quinoline scaffold and benzimidazole moiety were synthesized and their biological activities against VEGFR-2 and two human cancer cell lines were evaluated. Among them, compound 7s exhibited the most potent inhibitory activity against VEGFR-2 with IC50 of 0.03 μM and
