Novel small molecule protein arginine deiminase 4 (PAD4) inhibitors

Protein arginin deaminase 4 (PAD4) is a calcium dependent enzyme which catalyses the conversion of peptidyl-arginine into peptidyl-citrulline and is implicated in several diseases such as rheumatoid arthritis (RA) and cancer. Herein we report the discovery of novel small-molecule, non peptidic PAD4 inhibitors incorporating primary/secondary guanidine moieties.
