Protein arginine deiminase 4 (PAD4) is an enzyme that hydrolyzes peptidyl arginine residues to form citrulline and ammonia. This enzyme has been implicated in several disease states, e.g. rheumatoid arthritis, and therefore represents a unique target for the development of a novel therapeutic. A solution-phase synthesis of Cl-amidine, the most potent PAD4 inactivator described to date, has been developed. This synthesis proceeds in 80% yield over 4 steps at a significantly (12-fold) lower cost.
蛋白质精氨酸脱亚氨酶4（PAD4）是一种将肽基精氨酸残基水解以形成瓜氨酸和氨的酶。这种酶与多种疾病状态有关，例如类风湿性关节炎，因此是新型治疗药物开发的独特靶点。已开发出迄今为止描述的最有效的PAD4灭活剂Cl-脒的溶液相合成方法。该合成方法以80%的产率分4步进行，成本显著降低（12倍）。
