D-amino acid based protein arginine deiminase inhibitors: Synthesis, pharmacokinetics, and in cellulo efficacy.

ABSTRACT: The protein arginine deiminases (PADs) are known to play a crucial role in the onset and progression of multiple inflammatory diseases, including rheumatoid arthritis, inflammatory bowel disease, and cancer. However, it is not known how each of the five PAD isozymes contributes to disease pathogenesis. As such, potent, selective, and bioavailable PAD inhibitors will be useful chemical probes to elucidate the specific roles of each isozyme. Since D-amino amino acids often possess enhanced in cellulo stability, and perhaps unique selectivities, we synthesized a series of D-amino acid analogs of our pan-PAD inhibitor Cl-amidine, hypothesizing that this change would provide inhibitors with enhanced pharmacokinetic properties. Herein, we demonstrate that d-Cl-amidine and d-o-F-amidine are poten
