irreversible mechanism, which was dependent upon MPO catalysis, consistent with mechanism-based inactivation. N1-Substituted-6-arylthiouracils exhibited low partition ratios and high selectivity for MPO over thyroid peroxidase and cytochrome P450 isoforms. N1-Substituted-6-arylthiouracils also demonstrated inhibition of MPO activity in lipopolysaccharide-stimulated human whole blood. Robust inhibition of plasma
髓过氧化物酶(MPO)是一种血红素过氧化物酶,可催化次氯酸的产生。临床证据表明,MPO在各种自身免疫和炎性疾病(包括血管炎,心血管疾病和帕金森氏病)中具有因果作用,这表明MPO抑制剂可能代表了治疗选择。本文中,我们介绍了N -1取代的6-芳基硫尿嘧啶作为MPO的有效抑制剂和选择性抑制剂的设计,合成和临床前评价。抑制作用是通过时间依赖性的方式通过共价不可逆的机制进行的,该机制依赖于MPO催化,与基于机制的失活相一致。ñ与甲状腺过氧化物酶和细胞色素P450同工型相比,1-取代的6-芳基硫尿嘧啶对MPO的分配率低且选择性高。在脂多糖刺激的人全血中,N 1-取代的6-芳基硫尿嘧啶也显示出MPO活性的抑制作用。铅化合物2-(6-(5-氯-2-甲氧基苯基)-4-氧代-2-硫代氧代-3,4-二氢嘧啶-1(2 H)-基)乙酰胺证明了对血浆MPO活性的强烈抑制作用。(PF-06282999,8)口服给药时,
