  BACE1 inhibitors: A head group scan on a series of amides

  摘要：

  A series of amides bearing a variety of amidine head groups was investigated as BACE1 inhibitors with respect to inhibitory activity in a BACE1 enzyme as well as a cell-based assay. Determination of their basicity as well as their properties as substrates of P-glycoprotein revealed that a 2-amino-1,3-oxazine head group would be a suitable starting point for further development of brain penetrating compounds for potential Alzheimer's disease treatment.

  cis-(1S,2R) isomer 6 exhibited the most potent BACE1 inhibitory activity among them. X-ray structure analysis of the complex of 6 and BACE1 revealed that its unique binding mode is due to the apparent CH−π interaction between the rigid cyclopropane ring and the Tyr71 side chain. A derivatization study using 6 as a lead molecule led to the development of highly potent inhibitors in which the structure–activity

  使用具有sp 3杂化碳的构象限制方法来改善药物的结合活性正成为药物发现中的关键策略。我们将这种方法应用于BACE1抑制剂，并设计了四种立体异构体的环丙烷化合物，其中已知的am型抑制剂2的乙烯连接基被手性环丙烷环取代。这些化合物的合成和生物学评估表明，顺式-（1 S，2 R）异构体6在其中具有最强的BACE1抑制活性。配合物的X射线结构分析6BACE1揭示其独特的结合模式是由于刚性环丙烷环与Tyr71侧链之间存在明显的CH-π相互作用。使用6作为先导分子的衍生化研究导致开发了高效抑制剂，其中化合物的结构活性关系和结合方式与已知的am型抑制剂明显不同。
