  摘要：

  β-分泌酶（BACE1）的作用与阿尔茨海默病（AD）的发病密切相关。研究了氨基查尔酮衍生物抑制BACE1的能力。母体氨基查尔酮对BACE1的IC50值为两位数的微摩尔水平。通过将苯磺酰基衍生物引入氨基，活性提高了10倍或更多：1（IC50 = 48.2 μM）与4a（IC50 = 1.44 μM）以及2（IC50 = 17.7 μM）与5a（IC50 = 0.21 μM）。活性受查尔酮B环上羟基的位置和数量显著影响：3,4-二羟基5a（IC50 = 0.21 μM）> 4-羟基4a（IC50 = 1.44 μM）> 2,4-二羟基6（IC50 = 3.60 μM）> 2,5-二羟基7（IC50 = 16.87 μM）> 无羟基4b（IC50 = 168.7 μM）。Lineweaver-Burk和Dixon图及其二次重绘表明化合物5a是一种混合抑制剂，具有可逆和时间依赖性行为。强效的BACE1抑制剂4a、c、f和5a–c对其他两种与AD发病机制相关的酶，即乙酰胆碱酯酶（AChE）和丁酰胆碱酯酶（BChE），表现出中等抑制作用，IC50值分别在56.1 ~ 95.8 μM和19.5 ~ 79.0 μM之间。

  The 4'-(p-toluenesulfonylamino)-4-hydroxychalcone (TSAHC), which bears inhibitory chemotypes for both alpha-glucosidase and tyrosinase, was evaluated for tyrosinase activity and depigmenting ability relative to compounds designed to only target tyrosianse activity. TSAHC emerged to be a competitive reversible inhibitor of mushroom tyrosinase. More importantly, it was also able to return the melanin content of alpha-melanocyte stimulated by alpha-MSH to base levels unlike other inhibitors that only targeted tyrosinase. The Western blot for expression levels of proteins involved in melanogenesis showed that TSAHC significantly decreased three main tyrosinase related protein in melanin biosynthesis, tyrosinase, TRP-1 and TRP-2.

  The action of β-secretase (BACE1) is strongly correlated with the onset of Alzheimer’s disease (AD). Aminochalcone derivatives were examined for their ability to inhibit BACE1. Parent aminochalcones showed two digit micromolar IC50s against BACE1. Potency was enhanced 10-fold or more by introducing benzenesulfonyl derivatives to the amino group: 1 (IC50 = 48.2 μM) versus 4a (IC50 = 1.44 μM) and 2 (IC50 = 17.7 μM) versus 5a (IC50 = 0.21 μM). The activity was significantly influenced by position and number of hydroxyl groups on the chalcone B-ring: 3,4-dihydroxy 5a (IC50 = 0.21 μM) > 4-hydroxy 4a (IC50 = 1.44 μM) > 2,4-dihydroxy 6 (IC50 = 3.60 μM) > 2,5-dihydroxy 7 (IC50 = 16.87 μM) > des hydroxy 4b (IC50 = 168.7 μM). Lineweaver-Burk and Dixon plots and their secondary replots indicate that compound 5a was a mixed inhibitor with reversible and time-dependent behavior. Potent BACE1 inhibitors 4a,c,f, 5a–c showed moderate inhibition against two other enzymes implicated in AD pathogenesis, acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), with IC50s ranging between 56.1 ~ 95.8 μM and 19.5 ~ 79.0 μM, respectively.
