antimicrobial host-defense, has been implicated in chronic inflammatory diseases such as coronary artery disease. The design and evaluation of MPO inhibitors for the treatment of cardiovascular disease are reported herein. Starting with the MPO and triazolopyridine 3 crystal structure, novel inhibitors were designed incorporating a substituted pyrazole, which allowed for substituents to interact with hydrophobic
髓过氧化物酶 (MPO) 是抗微生物宿主防御中的一种关键酶,与慢性炎症性疾病(如冠状动脉疾病)有关。本文报道了用于治疗心血管疾病的 MPO 抑制剂的设计和评价。从 MPO 和三唑并吡啶3晶体结构开始,设计了包含取代吡唑的新型抑制剂,这允许取代基与活性位点中的疏水性和亲水性斑块相互作用。对取代吡唑的 SAR 探索导致哌啶17抑制活化中性粒细胞产生 HOCl,IC 50值为 2.4 μM,对甲状腺过氧化物酶 (TPO) 具有选择性。吡唑氮上烷基化化学的优化促进了许多类似物的制备,包括设计用于桥接活性位点的两个疏水区域的大环。寻求多种大环化策略来制备与活性位点最佳结合的类似物,从而产生具有 TPO 选择性的有效大环 MPO 抑制剂,例如化合物30。
