Compounds, methods of use, and processes for making inhibitors of complement factor D comprising Formula I, or a pharmaceutically acceptable salt or composition thereof wherein R12 or R13 on the A group is an ether (R32) are provided. The inhibitors described herein target factor D and inhibit or regulate the complement cascade at an early and essential point in the alternative complement pathway, and reduce factor D's ability to modulate the classical and lectin complement pathways. The inhibitors of factor D described herein are capable of reducing the excessive activation of complement, which has been linked to certain autoimmune, inflammatory, and neurodegenerative diseases, as well as ischemia-reperfusion injury and cancer.
本发明提供了包含式 I 或其药学上可接受的盐或组合物(其中 A 基上的 R12 或 R13 是醚(R32))的补体因子 D 抑制剂的化合物、使用方法和制造工艺。本文所述的抑制剂以因子 D 为靶点,在替代补体途径的早期和关键点抑制或调节补体级联,并降低因子 D 调节经典和凝集素补体途径的能力。本文所述的因子 D 抑制剂能够减少补体的过度活化,而补体的过度活化与某些自身免疫性、炎症性和神经退行性疾病以及缺血再灌注损伤和癌症有关。
