  Synthesis and Study of a Series of 3-Arylcoumarins as Potent and Selective Monoamine Oxidase B Inhibitors

  摘要：

  New series of 6-substituted-3-arylcoumarins displaying several alkyl, hydroxyl, halogen, and alkoxy groups in the two benzene rings have been designed, synthesized, and evaluated in vitro as human monoamine cuddase A and B (hMAO-A and hMAO-B) inhibitors. Most of the studied compounds showed a high affinity and selectivity to the hMAO-B isoenzyme, with IC50 values on nanomolar and picomolar range. Ten of the 22 described compounds displayed higher MAO-B inhibitory activity and selectivity than selegiline. Coumarin 7 is the most active compound of this series, being 64 times more active than selegiline and also showing the highest hMAO-B specificity. In addition, docking experiments were carried out on hMAO-A and h-MAO-B structures. This study provided new information about the enzyme inhibitor interaction and the potential therapeutic application of this 3-arylcoumarin scaffold.

  halogenated 3‐arylcoumarins were carried out with the aim of finding new structural and biological features. This series displays several alkyl, hydroxy, halogen, and/or alkoxy groups in both benzene rings of the 3‐arylcoumarin scaffold. Most of the compounds studied show high affinity and selectivity for the human monoamine oxidase B (hMAO‐B) isoenzyme, with IC50 values in the low nanomolar and picomolar range

  为了发现新的结构和生物学特征，进行了一系列新的卤代3-芳基香豆素的设计，合成，药理学评价和理论研究。该系列在3-芳基香豆素骨架的两个苯环中都显示几个烷基，羟基，卤素和/或烷氧基。研究的大多数化合物对人单胺氧化酶B（hMAO-B）同工酶显示出高亲和力和选择性，IC 50值在低纳摩尔和皮摩尔范围内。大多数评估的化合物显示出比司来吉兰（参考化合物）更高的MAO-B抑制活性和选择性。香豆素12（3-（3-溴苯基）-6-甲基香豆素）是活性最高的化合物（IC 50 = 134 p M），其活性是司来吉兰的140倍，对hMAO-B的特异性最高。为了更好地理解结构与活性之间的关系，对人单胺氧化酶（A和B）的结构进行了对接实验。最后，基于计算机生成的理化描述符，对被动血脑分区进行了预测。
