hydrazide derivatives, known to inhibit other aspartyl proteases. The derivatives were designed based on the docking study, synthesized and assessed for BACE-1 inhibition in vitro. Docking simulation predicted the binding of prototype acridin-9-yl hydrazide at BACE-1 active site. The enzyme–inhibitor complex was primarily stabilized by hydrogen bonds between the hydrazide part of the inhibitor and side
BACE-1,一种天冬氨酰蛋白酶,与阿尔茨海默氏病有关。在本文中,我们报告了已知可抑制其他天冬氨酰蛋白酶的acridin-9-酰肼衍生物的BACE-1抑制潜力。基于对接研究设计衍生物,合成并评估其对BACE-1的体外抑制作用。对接模拟预测原型Acridin-9-酰肼在BACE-1活性位点的结合。酶-抑制剂复合物主要通过抑制剂的酰肼部分与Gly11的侧链之间的氢键稳定,Gly11是10s环的重要氨基酸。cri啶基部分与Tyr71呈π-π堆积,而苯环则埋在S1腔中。酶抑制实验表明,所合成的化合物对化合物AA-13具有中等活性 在10 µM浓度下具有54.54%的抑制作用。
