  • Patent number: 12065459
    Abstract: 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 aryl, heteroaryl or heterocycle (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.
