  Based on the structural analysis of tricyclic scaffolds as butyrylcholinesterase (BuChE) inhibitors, a series of pyrazolo[1,5-c][1,3]benzoxazin-5(5H)-one derivatives were designed, synthesized and evaluated for their acetylcholinesterase (AChE) and BuChE inhibitory activity. Compounds with 5-carbonyl and 7- or/and 9-halogen substitutions showed potential BuChE inhibitory activity, among which compounds

  hMAO-A inhibitors, on which, the intramolecular cyclization led to a very interesting change of isoform selectivity. A series of selective hMAO-B inhibitors (3a–3u) with novel scaffold of tricyclic pyrazolo[1,5-d][1,4]benzoxazepin-5(6H)-one were designed and synthesized. Compound 3u (IC50 = 221 nM) exhibited the best inhibitory activity and isoform selectivity against hMAO-B, superior to selegiline (IC50 = 321 nM)

  基于我们最近报道的选择性hMAO-A抑制剂，分子内环化作用导致异构体选择性发生了非常有趣的变化。设计并合成了一系列具有新型三环吡唑并[1,5- d ] [1,4]苯并恶嗪-5（6 H）-支架的选择性hMAO-B抑制剂（3a - 3u）。化合物3u（IC 50  = 221 nM）表现出最佳的抑制活性和对hMAO-B的同工型选择性，优于司来吉兰（IC 50 ＝ 321nM），其是用于帕金森氏病的商业选择性hMAO-B抑制剂。模型研究表明，我们的化合物对hMAO-B的选择性取决于至少两个残基，即Ile 199和Cys 172（或对应于hMAO-A的Phe 208和Asn 181）。这些数据支持进一步的研究，以评估更有效的选择性hMAO-B抑制剂的合理设计。

  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.
