  三环吡唑并[1,5- d ] [1,4]苯并x庚因-5（6H）-一个支架衍生物：选择性BuChE抑制剂的合成及生物学评价

  摘要：

  BuChE抑制剂在晚期阿尔茨海默氏病（AD）患者的治疗中起着重要作用。合成了一系列三环吡唑并[1,5- d ] [1,4]苯并x庚因-5（6H）-一衍生物，并将其评估为乙酰胆碱酯酶（AChE）和丁酰胆碱酯酶（BuChE）抑制剂。一些衍生物表现出选择性的BuChE抑制活性，这受三环支架的C6位取代基的体积和苯环上卤素取代基的体积的影响。其中，具有二卤素和6-乙基取代基的化合物3f和3o表现出最强的活性（IC 50分别 为2.95、2.04μM和对BuChE的混合型，非竞争性抑制）。Eutomer （6 R）-3o比（6 S）-3o表现出更好的BuChE抑制活性。化合物3o显示出无毒，良好的ADMET特性和显着的神经保护活性。对接研究揭示了靶酶活性位点内的相同结合方向。化合物3o通过三个氢键，一个烷基相互作用和三个Pi-烷基相互作用与BuChE很好地结合。选择性BuChE抑制剂在进行性神经退行性疾病中具有潜在用途。

  Eight novel 4,5-tetrahydropyrazolo[1,5-d][1,4] oxazepine derivatives have been synthesized and purified to be screened for anticancer activity. By a modified TRAP assay, some titled compounds were tested against telomerase, and compound 4a showed the most potent inhibitory activity with IC50 value at 0.78 +/- 0.22 mu M. Western blot assays showed that compounds 4a and 4b could inhibit expression of Cyclin D1, TERT, phospho-AKT and PI3K/AKT pathway. (c) 2012 Elsevier Ltd. All rights reserved.

  A series novel 1-(3-substituted-5-pheny1-4,5-dihydropyrazol-1-y1)-2-thio-ethanone derivatives as potential telomerase inhibitors were designed and synthesized. The bioassays demonstrated that compounds 4a, 4f, 4j and 7b, 7d occupied high antiproliferative activity against SGC-7901, MGC-803, Bcap-37 and HEPG-2 cell lines. By a modified TRAP assay, some title compounds were tested against telomerase, and compound 4f showed the most potent inhibitory activity with IC50 value at 0.92 +/- 0.09 mu M. The mechanism of antitumor action indicated that title compounds 4f and 7b could suppress cell proliferation through inducing cell cycle arrest in G0/G1 phase. (C) 2013 Elsevier Masson SAS.

• Design and synthesis of novel 2-pyrazoline-1-ethanone derivatives as selective MAO inhibitors

  Thirty seven novel 2-pyrazoline-1-ethanone derivatives were designed, synthesized and evaluated as selective hMAO inhibitors. Among them, compounds 7h (IC50 = 2.40 mu M) and 12c (IC50 = 2.00 mu M) exhibited best inhibitory activity and selectivity against hMAO-A, surpassing that of the positive control Clorgyline (IC50 = 2.76 mu M). Based on selective activity of hMAO-A, SAR analysis showed that the order of N1 substituent contribution was bromo (3) > piperidinyl (4) > morpholinyl (5) > imidazolyl (6), and compounds with electron-withdrawing substituents (-F, -Cl) at C3 or C5 phenyl ring of 2-pyrazoline nucleus dedicated stronger MAO-A inhibitory activity. Molecular docking showed that compounds 7h and 12c were nicely bound to hMAO-A via two hydrogen bonds (SER209, GLU216), one Pi-Pi interaction and three hydrogen bonds (SER209, GLU216, TYR69), one Sigma-Pi interaction, respectively. In addition, the substituent at C3 position of 2-pyrazoline with the N1 acetyl has little effect on MAO-A inhibitory activity. These data support further studies to assess rational design of more efficiently selective hMAO inhibitors in the future. (C) 2014 Elsevier Ltd. All rights reserved.
