protease activities in various neutrophil mediated diseases. We designed and synthesized a series of dipeptidyl cyclopropyl nitrile compounds as putative CatC inhibitors. One compound, IcatCXPZ-01 ((S)-2-amino-N-((1R,2R)-1-cyano-2-(4'-(4-methylpiperazin-1-ylsulfonyl)biphenyl-4-yl)cyclopropyl)butanamide)) was identified as a potent inhibitor of both human and rodent CatC. In mice, pharmacokinetic studies
组织蛋白酶C(CatC)是一种二肽基外肽酶,可通过在嗜中性粒细胞分化的早幼粒细胞阶段去除骨髓细胞中N端前肽来激活中性粒细胞丝氨酸蛋白酶前体(弹性蛋白酶,蛋白酶3,组织蛋白酶G和NSP4)。所得的活性蛋白酶与慢性炎症和自身免疫疾病有关。因此,抑制CatC代表了一种抑制各种嗜中性粒细胞介导的疾病中过量蛋白酶活性的治疗策略。我们设计并合成了一系列二肽基环丙基腈化合物作为推定的CatC抑制剂。一种化合物IcatCXPZ-01((S)-2-氨基-N-((1R,2R)-1-氰基-2-(4'-(4-甲基哌嗪-1-基磺酰基)联苯-4-基)环丙基)丁酰胺))被确定为人类和啮齿类动物CatC的有效抑制剂。在老鼠中 药代动力学研究表明,IcatCXPZ-01在骨髓中积累,达到适合CatC抑制的水平。在单克隆抗胶原抗体诱导的类风湿性关节炎小鼠模型中皮下施用IcatCXPZ-01,具有统计学上显着的抗关节炎活性,且关节炎评分和足爪厚度持续降低。
