  Synthesis and preliminary evaluation of peptidomimetic inhibitors of human β-secretase

  摘要：

  Based on the structure of OM99-2 and the X-ray crystal structure of its complex with beta-secretase, a series of compounds containing the Leu*Ala hydroxyethylene isostere as a scissile bond substitution were designed. 31 compounds were synthesized and their beta-secretase inhibition activities were measured. It was found that isobutyl group was a better R(3) substitution as C-terminus in our target compounds, and 4-nitrobenzyl group was the best R(2) side chain. With the aid of molecular modeling, the binding modes of compounds 9 and 22 with beta-secretase were compared. The result revealed a stronger bonding mode of 22 than 9. This explored that the optimal length of this series of peptidomimetic inhibitors was P3-P2'. The molecular weights of compounds with this length are around 600. (C) 2010 Elsevier Masson SAS.
