Peptidomimetics as protein arginine deiminase 4 (PAD4) inhibitors
摘要:
The protein arginine deiminase 4 (PAD4) is a calcium-dependent enzyme, which catalyses the irreversible conversion of peptidyl-arginines into peptidyl-citrullines and plays an important role in several diseases such as in the rheumatoid arthritis, multiple sclerosis, Alzheimer's disease, Creutzfeldt-Jacob's disease and cancer. In this study, we report the inhibition profiles and computational docking toward the PAD4 enzyme of a series of 1,2,3-triazole peptidomimetic-based derivatives incorporating the beta-phenylalanine and guanidine scaffolds. Several effective, low micromolar PAD4 inhibitors are reported in this study.

carrying latent “click” functionality, followed by a nucleophile-promoted N1-dealkylation of the resulting strongly electrophilic intermediate triazolium salts, provides an efficient route to 1,5-disubstituted 1,2,3-triazoles. The azide and alkyne groups incorporated by N-alkylation can be submitted to further copper-catalyzedazide–alkyne and Huisgen cycloadditions to provide bis(1,2,3-triazoles)
