is provided. The compound or the salt thereof is represented by the following formula (1):
wherein A represents an alkyl group, a cycloalkyl group, an aryl group or a heterocyclic group, the group A may have a substituent; the ring B represents a 5- to 8-membered monocyclic heterocyclic ring or a condensed ring containing the monocyclic heterocyclic ring, the ring B may have a substituent; the ring C represents an aromatic ring, the ring C may have a substituent; L represents a linker comprising a main chain having 3 to 5 atoms selected from the group consisting of a carbon atom, a nitrogen atom, an oxygen atom and a sulfur atom, wherein at least one atom in the main chain is a hetero atom selected from the group consisting of a nitrogen atom, an oxygen atom and a sulfur atom, the linker L may have a substituent; and n is 0 or 1.

of 3 subunits, HOIP, HOIL-1L, and SHARPIN. Herein, we describe the discovery of inhibitors targeting the active site cysteine of the catalytic subunit HOIP usingfragment-based covalent ligand screening. We report the synthesis of a diverse library of electrophilic fragments and demonstrate an integrated use of protein LC–MS, biochemical ubiquitination assays, chemical synthesis, and protein crystallography

Rhodesain, the major cathepsin L-like cysteine protease in the protozoan Trypanosoma brucei rhodesiense, the causative agent of African sleeping sickness, is a well-validated drug target. In this work, we used a fragment-based approach to identify inhibitors of this cysteine protease, and identified inhibitors of T. brucei. To discover inhibitors active against rhodesain and T. brucei, we screened a library of covalent fragments against rhodesain and conducted preliminary SAR studies. We envision that in vitro enzymatic assays will further expand the use of the covalent tethering method, a simple fragment-based drug discovery technique to discover covalent drug leads.
