==Overview==
==Crystal structure of human beta secretase complexed with inhibitor==
We have synthesized and evaluated a series of conformationally biased P3, amide replacements based on an isophthalamide lead structure. The studies, resulted in the identification of the beta-secretase inhibitor 7m which, has an in vitro IC(50)=35 nM. The synthesis and biological activities of, these compounds are described.

Function

BACE1_HUMAN Responsible for the proteolytic processing of the amyloid precursor protein (APP). Cleaves at the N-terminus of the A-beta peptide sequence, between residues 671 and 672 of APP, leads to the generation and extracellular release of beta-cleaved soluble APP, and a corresponding cell-associated C-terminal fragment which is later released by gamma-secretase.[1] [2]
