• Serotonin derivatives as inhibitors of -secretase (BACE 1)
  作者：Takahashi、Miyazawa, Mitsuo

  DOI：10.1691/ph.2011.0789

  日期：——

  All serotonin derivatives described here (1–9) inhibited BACE 1 in a dose dependent manner. The 50% Inhibition Concentration (IC50 ) of N -cinnamoyl serotonin (1) was 86.7 ± 4.0 M. The peptide conjugation of serotonin derivatives influenced the BACE 1 inhibitory activity. Among serotonin derivatives (1–8), introduction of substituents, such as hydroxyl and methoxy groups at the 4 -position decreased the inhibitory activity (N - p -coumaroyl serotonin (2), N - p -methoxy cinnamoyl serotonin (3)). With a hydroxylgroup at the 4 -position, and the meta -hydroxy function being substituted by a hydroxyl group or methoxy group ( N caffeoyl serotonin (4), N -feruloyl serotonin (5)), inhibitory activity was weakened, (IC50 > 400 M). BACE 1 inhibitory activity was effected by the substituents of the cinnamic acid moiety. This is the first report on Structure-Activity-Relationships (SAR) for the BACE 1-inhibiting activity of serotonin derivatives. These serotonin derivatives, which have anti-oxidative effects as well are expected to be useful in the study of the mechanisms of Alzheimer's disease.

  这里描述的所有血清素衍生物 (1-9) 均以剂量依赖性方式抑制 BACE 1。 N-肉桂酰血清素 (1) 的 50% 抑制浓度 (IC50) 为 86.7 ± 4.0 M。血清素衍生物的肽缀合影响 BACE 1 抑制活性。在血清素衍生物 (1–8) 中，4 位羟基和甲氧基等取代基的引入降低了抑制活性（N - 对香豆酰血清素 (2)、N - 对甲氧基肉桂酰血清素 (3)） 。 4位有羟基，间位羟基被羟基或甲氧基取代（N咖啡酰血清素（4）、N-阿魏酰血清素（5）），抑制活性减弱，（IC50>400）米）。 BACE 1 抑制活性受肉桂酸部分的取代基影响。这是第一份关于血清素衍生物 BACE 1 抑制活性的结构-活性-关系 (SAR) 的报告。这些血清素衍生物也具有抗氧化作用，预计可用于阿尔茨海默病机制的研究。
• Synthesis and structure–activity relationships of phenylpropanoid amides of serotonin on tyrosinase inhibition
  作者：Toshiyuki Takahashi、Mitsuo Miyazawa

  DOI：10.1016/j.bmcl.2011.02.028

  日期：2011.4

  In this manuscript, we synthesized a series of phenylpropanoid amide of serotonin 1-9, analyzed their structural importance for two biologic activities (antioxidant activity and tyrosinase inhibitory activity). While the serotonin moiety and the amide linkage of serotonin derivatives affect antioxidant activity strongly, the serotonin moiety, the amide linkage and the cinnamic acid moiety affect tyrosinase inhibitory activity. Among tested compounds, compound 4 which contains cathechol moiety exhibited the most antioxidant activity (EC50 = 19.4 +/- 2.0 mu M), and compound 6 exhibited significant tyrosinase inhibitory activity (IC50 = 5.4 +/- 3.6 mu M). Our data suggests that a useful clue for the design and development of new tyrosinase inhibitors. (C) 2011 Elsevier Ltd. All rights reserved.
