  Design, synthesis, mechanistic and histopathological studies of small-molecules of novel indole-2-carboxamides and pyrazino[1,2-a]indol-1(2H)-ones as potential anticancer agents effecting the reactive oxygen species production

  摘要：

  A series of novel compounds carrying pyrazino[1,2-a]indol-1(2H)-one scaffold (5a-g) and their reaction intermediates, indole-2-carboxamides, (3a-g) were synthesized and evaluated for their ability to inhibit reactive oxygen species (ROS) generation, antioxidant activity and anticancer activity against a panel of cancer cell lines using MTT assay. The results showed that these compounds can inhibit ROS generation during the metabolic phase of phagocytosis in a dose-dependent manner where compounds 5d and 5e were the most potent samples with higher inhibitory activities (IC50 values 3.3 and 1.4 mu M, respectively) than that of the reference acetylsalicylic acid (IC50 = 9.7 mu M). Results for the determination of potential antioxidant properties of the synthesized compounds showed that compounds 5d and 5e containing pyrazino[1,2-a]indol-1-one backbone were the most acive and even comparable to Trolox. Compounds 3d-f and 5d-f with the least IC50 values in MTT assay were tested against three known anticancer targets EGFR, BRAF and Tubulin. Histopathological and immunohistochemical study were performed to determine the consequence of exposure to chronic low dose of chlorpyrifos on the testis of male mice and results revealed that these effects can be ameliorated by co-treatment with the most active antioxidant compounds 5d and 5e. Finally, molecular docking studies were performed to explore the binding mode of the most active compounds against EGFR and BRAF kinases. (C) 2018 Elsevier Masson SAS. All rights reserved.

  新型亲电和光亲和共价探针，用于映射大麻素1受体的变构位点

  摘要：

  与大麻素1受体（CB1R）的正构激动剂/拮抗剂相关的不良副作用（治疗多种影响人类的病理学易处理的靶标）极大地限制了其翻译潜力。CB1R负变构调节剂（NAMs）的最新发现通过提供一种可能更安全的治疗途径，重新引起了人们对CB1R的兴趣。为了阐明CB1R变构结合基序，从而促进合理的药物发现，我们报道了设计用于不可逆地结合CB1R变构位点的第一个共价配体的合成和生化特性。在两个经典CB1R NAM的关键位置引入一个亲电子基团或一个可光活化基团：Org27569（1）和PSNCBAM-1（2）。其中20（GAT100）成为功能测定中最有效的NAM，不表现出反向激动作用，并且表现为正构激动剂CP55,940结合的强健的正变构调节剂。这种新颖的共价探针可以用作表征CB1R变构配体结合基序的有用工具。
