Abstract

Peptidyl-acyloxymethyl ketones (AOMKs) belong to a class of selective, irreversible inhibitors (activity-based probes) widely used as chemical tools of investigating proteins, for example, in activity-based protein profiling. The synthesis of the AOMKs has always been challenging and current methodologies involve both solution and solid-phase synthesis. Herein, the synthesis of a new scaffold useful for the preparation of peptidyl-AOMKs is reported and it is demonstrated that the new synthetic probes bearing a 4-functionalized 2,6-dimethylbenzoate efficiently inhibit cysteine proteases like cathepsin B.
