title: Design and synthesis of novel fluoropeptidomimetics as potential mimics of the transition state during peptide hydrolysis.
abstract: alpha-Fluoroamino acids were targeted in our ongoing efforts to design novel fluoropeptidomimetics (1) as potential protease inhibitors. alpha-Fluoroglycine derivative (2) and alpha-fluoro-beta-aminoethanethiol derivatives (3-9) were synthesized for the first time en route to obtain the peptidomimetic moiety 1. The stability of 2-9 was investigated under organic as well as aqueous conditions. The stability of 3-9 under acidic and basic conditions, the effect of substitution at C-2 position, and potential biological activities are discussed.
