The protein arginine deiminases (PADs) are a family of enzymes that catalyze the post-translational hydrolytic deimination of arginine residues. Four different enzymologically active PAD subtypes have been characterized and exhibit tissue-specific expression and association with a number of different diseases. In this Article we describe the development of an approach for the reliable discovery of low molecular weight, nonpeptidic fragment substrates of the PADs that then can be optimized and converted to mechanism-based irreversible PAD inhibitors. The approach is demonstrated by the development of potent and selective inhibitors of PAD3, a PAD subtype implicated in the neurodegenerative response to spinal cord injury. Multiple structurally distinct inhibitors were identified with the most potent inhibitors having >10,000 min(-1) M-1 k(inact)/K-I values and >= 10-fold selectivity for PAD3 over PADs 1, 2, and 4.

We have worked out the synthesis of two bifunctional photochemically active peptide derivatives based on a side chain ruthenium labeled amino acid. The ruthenium modified amino acid [H-OrnRu(bipy)(2)m}-OH](PF6)(3) (Orn = ornithine, in = 4-carbonyl-4'-methyl-2,2'-bipyridyl) was used as a module for the synthesis of a [Ru(bipy)(3)]-(Fc-CONHR) (Fc-CONHR = ferrocene-1-carboxamide), and a [Ru(bipy)(3)]-Tyr (Tyr = tyrosine) chromophore-quencher conjugate. The complex [Fc-OrnRu(bipy)(2)m}-OMe](PF6)(2) shows efficient luminescence quenching by energy transfer. Electron transfer from phenolate to ruthenium occurs in the dipeptide [Boc-Tyr-OrnRu(bipy)(2)m}-O](PF6) above pH 9. Implications for the development of cooperative sensing devices and light energy converting peptides are discussed. (C) 2002 Elsevier Science B.V. All rights reserved.
