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 R
12
or R
13
on the A group is an amino substituent (R
32
) 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.
本文提供了公式I或其药学上可接受的盐或组合物所组成的抑制补体因子D的化合物、使用方法和制备过程,其中A组上的R12或R13是氨基取代基(R32)。所述抑制剂靶向因子D并在替代性补体途径的早期和关键点上抑制或调节补体级联反应,并减少因子D调节经典和凝集素补体途径的能力。本文所述的因子D抑制剂能够减少过度激活补体,这与某些自身免疫性、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。
