DF2593A (DF 2593A) is a potent, selective, noncompetitive allosteric inhibitor of C5aR with IC50 of 5 nM (C5a-induced human PMN migration inhibition), and rat and mouse orthologs (IC50=6.0 nM and IC50=1.0 nM, respectively); dispalys >1,000-fold selective versus other chemoattractants, including CXCL8 and CXCL1 (CI50>10 uM), as well as on a panel of different GPCRs and ion channels; DF2593A demonstrated antinociceptive effects in several models of inflammatory pain and effectively inhibited articular hyperalgesia in CFA-induced mechanical and thermal hyperalgesia and arthritic nociception.
