    The synthesis, evaluation, and structure-activity relationships of a class of γ-lactam 1,3-diaminopropan-2-ol transition-state isostere inhibitors of BACE are discussed. Two strategies for optimizing lead compound 1a are presented. Reducing the overall size of the inhibitors resulted in the identification of γ-lactam 1i, whereas the introduction of conformational constraint on the prime-side of the inhibitor generated compounds such as the 3-hydroxypyrrolidine inhibitor 28n. The full in vivo profile of 1i in rats and 28n in Tg 2576 mice is presented.
