  Cyclic Hydroxyamidines as Amide Isosteres: Discovery of Oxadiazolines and Oxadiazines as Potent and Highly Efficacious γ-Secretase Modulators in Vivo

  摘要：

  Cyclic hydroxyamidines were designed and validated as isosteric replacements of the amide functionality. Compounds with these structural motifs were found to be metabolically stable and to possess highly desirable pharmacokinetic profiles. These designs were applied in the identification of gamma-secretase modulators leading to highly efficacious agents for reduction of central nervous system A beta(42) in various animal models.
