  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。

  In the present communication, we report the synthesis, pharmacological evaluation, theoretical evaluation of absorption, distribution, metabolism and excretion properties and structure–activity relationship study of a selected series of 3-arylcoumarins (compounds 1–9). Adenosine receptors (ARs) binding activity and selectivity of the synthesized compounds 1–9 were evaluated in this study. Different substituents were introduced in both benzene rings of the evaluated scaffold, at positions 6 and 3′ or 4′ of the moiety. The lack of data on the 3-arylcoumarin scaffold encouraged us to explore the ARs' binding activity of a selected series of derivatives.

  A new series of coumarins (compounds 1–9) were synthesized and evaluated by radioligand binding studies towards ARs.

  Analysing the experimental data, it can be observed that neither the simple 3-arylcoumarin nor the 4′-nitro derivatives presented detectable binding affinity for the evaluated receptors, although most of the other substituted derivatives have good binding affinity profiles, especially against the hA1/hA3 or only hA3 AR.

  The most remarkable derivative is compound 2, presenting the best affinity for hA3 AR (Ki = 2680 nM) and significant selectivity for this subtype.

  摘要：在这份研究中，我们报告了一系列选定的3-芳基香豆素化合物（化合物1-9）的合成、药理评价、吸收、分布、代谢和排泄性质的理论评价以及构效关系研究。我们对合成的化合物1-9进行了腺苷受体（ARs）结合活性和选择性评估。在评估的骨架的苯环中引入了不同的取代基，分别位于6位和3'或4'位置。对3-芳基香豆素骨架缺乏数据促使我们探索一系列衍生物的ARs结合活性。 方法：合成了一系列新的香豆素化合物（化合物1-9），并通过放射配体结合研究评估其对ARs的结合。 主要发现：分析实验数据，可以观察到简单的3-芳基香豆素和4'-硝基衍生物对评估的受体没有可检测的结合亲和力，尽管大多数其他取代衍生物具有良好的结合亲和力特性，特别是对hA1/hA3或仅hA3 AR。 结论：最显著的衍生物是化合物2，对hA3 AR具有最佳亲和力（Ki = 2680 nM），并对这个亚型具有显著的选择性。
• Highly Regioselective α-Arylation of Coumarins<i>via</i>Palladium-Catalyzed CH Activation/Desulfitative Coupling

  AbstractA novel regioselective α‐arylation of coumarins with readily available arenesulfonyl chlorides and sodium arenesulfinates via palladium‐catalyzed direct CH functionalizations under mild reaction conditions is described. This protocol presents an unexpected and highly regio‐controlled arylation of coumarins at C‐3 to construct interesting 3‐arylcoumarins with fascinating biological and fluorescent properties. The regioselectivity observed is in sharp contrast with that expected for the Heck reactions.magnified image
