The identification of a series of sulfonyl-amino-acetamides as BACE-1 (β-secretase) inhibitors for the treatment of Alzheimer’s disease is reported. The derivatives were designed based on the docking simulation study, synthesized and assessed for BACE-1 inhibition in vitro. The designed ligands revealed desired binding interactions with the catalytic aspartate dyad and occupance of S1 and S2′ active
据报道,已鉴定出一系列磺酰基-氨基-乙酰胺类药物作为用于治疗阿尔茨海默氏病的BACE-1(β-分泌酶)抑制剂。基于对接模拟研究设计衍生物,合成并评估其对BACE-1的体外抑制作用。设计的配体揭示了与催化天冬氨酸二聚体的理想结合相互作用以及对S1和S2'活性位点区域的占据。这些计算机模拟结果与体外活性密切相关。在合成的33种化合物中,有12种化合物在10μM浓度下显示出明显的抑制作用。活性最高的化合物2.17S对BACE-1的IC 50为7.90μM,这与计算机对接研究的结果相吻合。
