Abstract
To inhibit the HIV-1 protease dimerization necessary to exhibit enzymatic activity, we synthesized and evaluated a new beta-sheet peptide (compound 1), containing 4-(2-aminoethyl)-6-dibenzofuranpropionic acid as a conformationally restricted linker and a non-peptidic beta-strand mimetic, 2-[3-([2-[(9-fluorenylmethoxy)carbonyl]hydrazino]carbonyl)-4-methoxyanilino]-2-oxoacetic acid (Fmoc-Hao-OH, compound 2). Kinetic analysis showed that compound 1 inhibited the dimerization of HIV-1 protease by a dissociative mechanism with a K(id) value of 5.4 microM at 37 degrees C (pH 5.0). However, compound 2 showed a small shift in the slope of the lines in the Zhang-Poorman plot (K(id)=9.1 microM), suggesting that compound 2 inhibits the dimerization of HIV-1 PR not only through a dissociative mechanism but also through an active-site directed mechanism partly. This is the first study of a non-peptidic inhibitor of HIV-1 protease dimerization.

Abstract
In a previous report, Nowick and co-workers described beta-strand mimic A, which duplicates the structure and hydrogen-bonding pattern of one edge of a tetrapeptide in a beta-strand conformation (Nowick, J. S.; Pairish, M.; Lee, I. Q.; Holmes, D. L.; Ziller, J. W. J. Am. Chem. Soc. 1997, 119, 5413). Beta-strand mimic A is composed of a 5-amino-2-methoxybenzoic acid unit linked to a 5-hydrazino-2-methoxybenzamide unit by means of an acylhydrazine group. This paper introduces two related beta-strand mimics (B and C) and reports their comparison to beta-strand mimic A. Beta-strand mimic B is composed of a 5-amino-2-methoxybenzoic acid unit linked by a diacylhydrazine group to a fumaramide unit; beta-strand mimic C is composed of a 5-amino-2-methoxybenzoic acid unit linked by a diacylhydrazine group to a peptide. Beta-strand mimics A-C were connected to tripeptide (Phe-Ile-Leu) groups by means of 1,2-diaminoethane diurea turn units to form artificial beta-sheets 1-3. 1H NMR studies, involving ROESY, chemical shift, coupling constant, and variable temperature experiments, reveal that 1-3 adopt hydrogen-bonded antiparallel beta-sheet conformations and establish that all three templates are viable beta-strand mimics.
