were designed to inactivate humanleukocyteelastase (HLE) in three steps: first acylation of active-site serine; second, creation of a powerful new electrophilic center; third, covalent capture of a nucleophile from the enzyme. Both types do irreversibly inactivate HLE, and structure-activity relationships are in accord with the proposed mechanism. In each series, one molecule of the most active compound
