  P3 cap modified Phe*-Ala series BACE inhibitors

  摘要：

  With the aim of reducing molecular weight and adjusting log D value of BACE inhibitors to more favorable range for BBB penetration and better bioavailability, we synthesized and evaluated several series of P3 cap modified BACE inhibitors obtained via replacement of the P3 NHBoc moiety as seen in 3 with other polar functional groups such as amino, hydroxyl and fluorine. Several promising inhibitors emerging from this P3 cap SAR study (e.g., 15 and 19) demonstrated good enzyme inhibitory potencies (BACE-1 IC50 < 50 nM) and whole cell activities (IC50 similar to 1 muM).

  日期：——

  Syntheses of β,β,β- and γ,γ,γ-trifluoro-α-amino, α-hydroxy and α-mercapto acids using hexafluoroacetone as protecting and activating reagent are described. The key step of the syntheses is the transformation of an ω-carboxy group into a trifluoromethyl group on treatment with sulfur tetrafluoride. The carboxy activated species obtained are suitable for direct incorporation into peptide and depsipeptide fragments. RP-HPLC experiments and Mosher's TMPA method (1H and 19F) demonstrate that the reaction sequence occurs without racemization.
