Two pathways were developed and investigated for the synthesis of the ‘aged’- nonapeptide nerve-agent bioadduct of human butyrylcholinesterase (BuChE). Considering the fast ageing of nerve-agent adducts of BuChE in patients and biomedical samples this target molecule is of paramount relevance for quantitative analysis with respect to the Chemical Weapons Convention. Two approaches using a precursor bearing a hydroxyl on its phosphonyl moiety and a benzyl protected precursor were considered. Several impurities were identified and circumvented during the optimization of the peptide synthesis step. The ‘aged’-nonapeptide adduct was successfully synthesized by solid-phase-peptide-synthesis (SPPS).
