Extended Data Fig. 1: Small molecule inhibitors of USP30.

Chemical structures of representative examples of small molecule USP30 inhibitors are given together with characterization data and references. Cyanamides of covalent inhibitors form isothiourea linkages with the active site cysteine of USP30. Non-covalent inhibitors belong either to chemical series which were developed from phenylalanine derivatives (with either a benzenesulfonamide or a naphthylsulfonamide) or are natural product derivatives.
