Over the past decade targeted covalent inhibitors have undergone a renaissance due to the clinical validation and regulatory approval of several small molecule therapeutics that are designed to irreversibly modify their target protein. Invariably, these compounds rely on the serendipitous placement of a cysteine residue proximal to the small molecule binding site; while this strategy has afforded numerous successes, it necessarily limits the number of proteins that can be targeted by this approach. This drawback has led several research groups to develop novel methodologies that target non-cysteine residues for covalent modification. Herein, we survey the current literature of warheads that covalently modify non-cysteine amino acids in proteins.
