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 ether substituent (R32) are provided. The inhibitors described herein target Factor D and inhibit or regulate the complement cascade. The inhibitors of Factor D described herein reduce the excessive activation of complement.
