  Design and synthesis of highly active Alzheimer’s β-secretase (BACE1) inhibitors, KMI-420 and KMI-429, with enhanced chemical stability

  摘要：

  Recently, we reported potent and small-sized BACE1 inhibitors KMI-358 and KMI-370 in which the Glu residue is replaced by a beta-N-oxalyl-DAP (L-alpha,beta-diaminopropionyl) residue at the P-4 position. The beta-N-oxalyl-DAP group is important for enhancing BACE1 inhibitory activity, but these inhibitors isomerized to alpha-N-oxalyl-DAP derivatives in solvents. Hence, we used a tetrazole moiety as a bioisostere of the free carboxylic acid of the oxalyl group. KMI-420 and KMI-429, containing a tetrazole ring, showed improved stability and potent enzyme inhibitory activity. (C) 2004 Elsevier Ltd. All rights reserved.
