Peptidyl arginine deiminases have been shown to be hyperactive in neurodegenerative diseases including multiple sclerosis. An α-amino acid-based core structure, derived from a hydantoin core, with unique heterocycles on the side chains were synthesized as potential noncovalent inhibitors of PAD enzymes. ⋯ At the same dose, compound 23 also reversed physical disability and cleared the brain of T-cell infiltration in an EAE mouse model of multiple sclerosis (MS). This novel series of compounds show promise for further development as disease modifying agents for the potential treatment of MS.
