A series of Nalpha-acyl-alpha-amino acid-(arylaminoethyl)amides were found to be potent and noncovalent cathepsin S inhibitors. Compound 20 possessed high cathepsin S affinity (Ki=3.3 nM) and showed excellent selectivity over cathepsin K, L, F, and V. Molecular modeling, design, synthesis, and in vitro activity are described.
