  Discovery of a series of selective and cell permeable beta-secretase (BACE1) inhibitors by fragment linking with the assistance of STD-NMR

  摘要：

  Two beta-secreatase (BACE1) inhibitors from natural products (cinnamic acid and flavone) were linked to furnish potent, cell permeable BACE1 inhibitors with noncompetitive mode of inhibition, with the assistance of saturated transfer difference (STD)-NMR technique. Some of these conjugates also exhibited selective BACE1 inhibition over other aspartyl proteases such as BACE-2 and renin, as well as poor cytotoxicity. Taken together, conjugates 4 represent a new series of BACE inhibitors warrants further investigation for their potential in Alzheimier's disease therapy.

  摘要：

  作为我们研究的延伸，旨在发现一种对组胺和慢反应物质 (SRS) 具有双重活性的新型化合物，我们合成了两种类型的吲哚哌啶衍生物，3 和 4-20。体内抗过敏活性和体外抗 SRS 活性测试表明 (2E, 4E) -5- (3,5 - 二甲氧基 - 4 - 羟基苯基) -N- (2- (4- (1H - indole - 3 ‐Yl) 哌啶 ‐ 1 ‐ yl) 乙基) ‐2,4 - 戊二烯酰胺 (11) 表现出有效的双重活性，分别为 ED50 = 0.89 mg / kg 和 IC50 = 1.43 μM。然而，当在豚鼠中口服给药时，未改变的 11 的血浆浓度非常低。这一结果可以通过快速形成葡萄糖醛酸结合物来解释。
