  Synthesis and evaluation of new coumarin derivatives as potential atypical antipsychotics

  摘要：

  In this paper, we report the synthesis of novel, potential antipsychotic coumarin derivatives combining potent dopamine D-2, D-3 and serotonin 5-HT1A 5-HT(2)A receptors properties. We describe the structure activity relationship that leads us to the promising derivative: 7-(4-(4-(6-fluorobenzo[d]isoxazol-3-yl) piperidin-1-yl)butoxy)-6-methyl-2,3-dihydrocyclopenta[c]chromen-4(1H)-one 27. The unique pharmacological features of compound 27 are a high affinity for dopamine D-2, D-3 and serotonin 5-HT1A, 5-HT2A receptors, together with a low affinity for H-1 receptor (to reduce the risk of obesity under chronic treatment). In animal models, compound 27 inhibited apomorphine-induced climbing and MK-801-induced hyperactivity without observable catalepsy at the highest dose tested. In particular, compound 27 was more potent than clozapine. (C) 2014 Elsevier Masson SAS. All rights reserved.

  There is a continued need to develop new selective human monoamine oxidase (hMAO) inhibitors that could be beneficial for the treatment of neurological diseases. However, hMAOs are closely related with high sequence identity and structural similarity, which hinders the development of selective MAO inhibitors. “Three-Dimensional Biologically Relevant Spectrum (BRS-3D)” method developed by our group

  持续需要开发新的选择性人单胺氧化酶 (hMAO) 抑制剂，其可能有益于治疗神经系统疾病。然而，hMAOs 与高序列同一性和结构相似性密切相关，这阻碍了选择性 MAO 抑制剂的发展。我们团队开发的“三维生物相关光谱（BRS-3D）”方法在受体和酶配体的亚型选择性研究中证明了其有效性。在这里，我们报告了一系列新的 C7 取代香豆素，无论是合成的还是商业购买的，它们被确定为选择性 hMAO 抑制剂。大多数化合物表现出很强的活性，IC50 值（半抑制浓度）范围从亚微摩尔到纳摩尔。化合物，FR1 和 SP1，被鉴定为最具选择性的 hMAO-A 抑制剂，IC50 值分别为 1.5 nM（选择性指数 (SI) < -2.82）和 19 nM（SI < -2.42）。FR4 和 FR5 显示出最有效的 hMAO-B 抑制活性，IC50 为 18 nM 和 15 nM（SI > 2.74 和 SI > 2.

  A series of coumarin derivatives bearing a pyrrole scaffold were designed, prepared, and assessed for their in vitro antifungal activities against six phytopathogenic fungi. The antifungal activity screening results suggest that some synthesized hybrids exhibited potential fungicidal activities against the tested fungi. In particular, compounds 6j, 6k, 6o, 6p, and 6r displayed significant antifungal

  The work provides a new model for the prediction of the MAO-A and -B inhibitor activity by the use of combined complex networks and QSAR methodologies. On the basis of the obtained model, we prepared and assayed 33 coumarin derivatives, and the theoretical prediction was compared with the experimental activity data. The model correctly predicted 27 compounds, and most of the active derivatives showed

  这项工作通过使用复杂的网络和QSAR方法，为预测MAO-A和-B抑制剂的活性提供了一个新模型。在获得的模型的基础上，我们制备并测定了33种香豆素衍生物，并将理论预测值与实验活性数据进行了比较。该模型可以正确预测27种化合物，并且大多数活性衍生物对MAO-A和MAO-B同种型的IC 50值均在muM-nM范围内。化合物14显示出与用作参照抑制剂的盐酸高粱碱相同的MAO-A抑制活性（IC 50 = 7.2 nM），并且具有最高的MAO-A特异性（比MAO-B高1000倍）。另一方面，化合物24（IC 50 = 1.2 nM）和28（IC 50 = 1.5 nM）的活性高于司来吉兰（IC 50 = 19）。
