Front Cover: Synthesis and Structural Characterization of Macrocyclic Plasmin Inhibitors (ChemMedChem 6/2023)

The Front Cover shows new macrocyclic plasmin inhibitors containing a C-terminal P1 benzylamine group. Their N-terminal substitution provided analogues with sub-nanomolar Ki values. Additional inhibitors containing an asymmetric linker possess Ki values close to 2 nM. For the first time, crystal structures of these macrocyclic inhibitors in complex with a Ser195Ala microplasmin mutant were determined, which explain their excellent potency and selectivity.
