  Design, biological evaluation and 3D QSAR studies of novel dioxin-containing triaryl pyrazoline derivatives as potential B-Raf inhibitors

  摘要：

  A series of novel dioxin-containing triaryl pyrazoline derivatives C1-C20 have been synthesized. Their B-Raf inhibitory and anti-proliferation activities were evaluated. Compound C6 displayed the most potent biological activity against B-Raf(V600E) and WM266.4 human melanoma cell line with corresponding IC50 value of 0.04 mu M and GI(50) value of 0.87 mu M, being comparable with the positive controls and more potent than our previous best compounds. Moreover, C6 was selective for B-Raf(V600E) from B-Raf(WT), C-Raf and EGFR and low toxic. The docking simulation suggested the potent bioactivity might be caused by breaking the limit of previous binding pattern. A new 3D QSAR model was built with the activity data and binding conformations to conduct visualized SAR discussion as well as to introduce new directions. Stretching the backbone to outer space or totally reversing the backbone are both potential orientations for future researches. (C) 2016 Elsevier Ltd. All rights reserved.

  摘要：

  本研究记录了氧化查尔酮（O1-O26）衍生物的合成及其抑制单胺氧化酶的能力。检查的所有26种衍生物均显示出对MAO-B的有效抑制活性。化合物O23对MAO-B表现出最大的抑制活性，IC 50值为0.0021 µM，其次是化合物O10和O17（IC 50分别 为0.0030和0.0034 µM）。此外，大多数衍生物均能有效抑制MAO-A和O6，是最有效的抑制剂，IC 50值为0.029 µM，其次是O3，O4，O9和O3。O2（IC 50 分别为0.035、0.053、0.072和0.082 µM）。O23对MAO-B的选择性指数（SI）值为138.1，而O20（对于MAO-B的IC 50值为0.010 µM）具有非常高的SI> 4000。在透析实验中，O6和O23对MAO-A和MAO-B的抑制作用分别恢复到了各自的可逆参考水平，表明这两种都是可逆抑制剂。动力学研究表明，O6和O23分别以K

  A method for increasing the rate of phosphine oxide reduction, preferably during a Wittig reaction comprising use of an acid additive is provided. A room temperature catalytic Wittig reaction (CWR) the rate of reduction of the phosphine oxide is increased due to the addition of the acid additive is described. Furthermore, the extension of the CWR to semi-stabilized and non-stabilized ylides has been accomplished by utilization of a masked base and/or ylide-tuning.

  One ring no longer rules them all: Employment of 2.5–10 mol % of 4‐nitrobenzoic acid with phenylsilane led to the development of a room temperature catalytic Wittig reaction (see scheme). Moreover, these enhanced reduction conditions also facilitated the use of acyclic phosphine oxides as catalysts for the first time. A series of alkenes were produced in moderate to high yield and selectivity.

  一个环不再完全统治一切：用2.5-10 mol％的4-硝基苯甲酸与苯基硅烷一起使用导致了室温催化Wittig反应的发展（参见方案）。此外，这些增强的还原条件还促进了首次将无环氧化膦用作催化剂。以中等至高收率和选择性生产了一系列烯烃。
