Structure-based design and synthesis of a number of potent and selective memapsin2inhibitors are described. These inhibitors were designed based upon the X-ray structure of memapsin 2-bound inhibitor 3 that incorporates methylsulfonyl alanine as the P2-ligand and a substituted pyrazole as the P3-ligand. Of particular importance, we examined the ability of the substituted isophthalic acid amide derivative

Structure-based design, synthesis, and biological evaluation of a series of peptidomimetic beta-secretase inhibitors incorporating hydroxyethylamine isosteres are described. We have identified inhibitor 24 which has shown exceedingly potent activity in memapsin2 enzyme inhibitory (K(i) 1.8 nM) and cellular (IC(50)=1 nM in Chinese hamster ovary cells) assays. Inhibitor 24 has also shown very impressive

This paper introduces a chemical model of a beta-sheet that dimerizes through parallel beta-sheet interactions in CDCl3 solution. The model consists of two C-terminally linked dipeptides connected to a molecular template. H-1 NMR studies establish the beta-sheet folding and dimerization of the model system. This system corroborates that linking two peptide strands and blocking one edge of the assembly creates soluble, easy-to-study systems that participate in the types of interactions that occur widely in peptide and protein aggregates.
