Abstract (Summary)

Butyrylcholinesterase (BuChE) is known to show increased activity in patients with Alzheimer’s Disease and likely contributes to the symptomatic decline in cognition. Therefore, it is an attractive goal to develop a synthetic drug that is highly specific for inhibiting BuChE. Herein, we build upon previous organophosphorus inhibitor designs by changing substituents on the phosphorus center in two ways: 1) the addition of substrate features to mimic the cationic-pi interaction, and 2) the substitution of oxygen for sulfur atoms to incorporate a better leaving group. However, for the former, stereochemistry on the phosphorus center was also evaluated for using enantiomerically enriched mixtures. Herein, the synthesis, purification, and biological characterization of a library of inhibitors are detailed. The results of these experiments increase our understanding of the molecular interactions between the potential drug candidate and its target and inform us on how to design more potent, target-specific drugs.
