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。
