Human neutrophil elastase (HNE) is a key driver of inflammation in many cardiopulmonary and systemic inflammatory and autoimmune conditions. Overshooting high HNE activity is the consequence of a disrupted protease–antiprotease balance. Accordingly, there has been an intensive search for potent and selective HNE inhibitors with suitable pharmacokinetics that would allowing oral administration in patients
人类中性粒细胞弹性蛋白酶(HNE)是在许多心肺和全身性炎症和自身免疫性疾病中炎症的关键驱动因素。过高的HNE活性过高是蛋白酶-抗蛋白酶平衡被破坏的结果。因此,人们一直在寻找具有合适药代动力学的有效的和选择性的HNE抑制剂,其将允许在患者中口服给药。基于化学探针BAY-678和临床候选物BAY 85-8501,我们沿着亲代嘧啶酮铅系列的赤道探索了进一步的环拓扑。在东部对新型环系统进行环空处理,生成咪唑并,三唑并四唑并嘧啶,以确保除HNE的S1和S2口袋外还存在其他抑制剂-HNE接触。哒嗪的西环化产生了极性的嘧啶并哒嗪BAY‐8040,结合了出色的效价和选择性以及有希望的药代动力学特征。在由一丁香酚碱诱导的肺动脉高压大鼠模型中显示了在减少心脏重塑和改善心功能方面的体内功效。这证明了在动物体内的概念证明。
