Small molecule LpxC inhibitors against gram-negative bacteria

WebEnzyme inhibitors are classified as reversible or irreversible. An irreversible inhibitor forms a stable complex with the enzyme. As a result, the enzyme is permanently inactivated or, at best, is slowly reactivated (requiring hours or days for reversal). Usually, the irreversible inhibitor forms a covalent bond with the enzyme.
