these aggressive cancers. Herein, we describe a covalentfragment screen that identified the chloroacetohydrazidescaffold as a covalent UCHL1 inhibitor. Subsequent optimization provided an improved fragment with single-digit micromolar potency against UCHL1 and selectivity over the closely related UCHL3. The molecule demonstrated efficacy in cellular assays of metastasis. Additionally, we report a ligand-bound
