  Synthesis and Biological Evaluation of a Novel Series of 1,3-Dicoumarinyl-5-aryl-2-pyrazolines

  摘要：

  In the present paper novel 1,3,5-trisubstituted 2-pyrazolines (4a-q) were synthesized via condensation of different substituted 3-cinnamoyl-2-oxo-2H-chromenes (2a-q) with 2-(4-methyl-2-oxo-2H-chromen-7-yloxy)acetohydrazide (3). Chalcones were prepared via Claisen-Schmidt condensation by refluxing 3-acetyl-2-oxo-2H-chromen (1) with corresponding aldehydes in ethanol, in the presence of piperidine. All of these compounds were characterized by means of their IR, (1)H NMR and LC/MS/MS spectroscopic data and elemental microanalysis. Chalcones and pyrazolines were screened for their antioxidant and iron chelating activity.

  which a radical can act. Electrochemistry is a useful tool for this purpose. In this work, the cyclic voltammetry-based methodology was used to generate superoxide anion radical through oxygen one-electron reduction in a dimethyl sulfoxide solution. Plotting the remaining percentage of initial current against compound concentration we can establish a Reactivity Index (RI50), for comparative purpose

  本研究揭示了对合成香豆素的超氧化物自由基阴离子反应性。自由基在许多疾病中都起着重要作用，并且还具有保护功能。因此，我们必须保持其浓度平衡，这就是香豆素等外源抗氧化剂变得重要的地方。由于自由基可以发挥多种作用机理，因此有多种方法可以量化抗氧化剂的效率。电化学是用于此目的的有用工具。在这项工作中，使用基于循环伏安法的方法通过在二甲亚砜溶液中通过氧单电子还原生成超氧阴离子自由基。将剩余的初始电流百分比与化合物浓度作图，我们可以建立反应活性指数（RI 50），以作比较。该指数是指将初始峰值电流降低50％的浓度值。对电生成的超氧阴离子自由基反应性最高的香豆素是3-乙酰基-7,8-二羟基香豆素（7,8-香豆）。
