Mechanism-based Inhibitors of Serine Proteases with High Selectivity Through Optimization of S' Subsite Binding

A series of mechanism-based inhibitors designed to interact with the S’ subsites of serine proteases was synthesized and their inhibitory activity toward the closely-related serine proteases human neutrophil elastase (HNE) and proteinase 3 (PR 3) was investigated. The compounds were found to be time-dependent inhibitors of HNE and were devoid of any inhibitory activity toward PR 3.
