C5aR Antagonist, DF2593A

An orally available, blood-brain barrier permeant piperidinylbutanamide compound that acts as a highly potent, selective, non-competitive and allosteric antagonist of C5a receptor (C5aR). Shown to effectively block C5a-induced human PMN migration (IC₅₀ = 5.0 nM) and is also effective in rat and mouse orthologs (IC₅₀ = 6.0 and 1 nM for rat and mouse, respectively). Exhibits good selectivity against a panel of GPCRs and ion channels screened and is shown to be completely inactive in a prostaglandin E2 production assay (~10 µM). Blocks C5a-induced and carrageenan-induced hyperalgesia in mice without any sedative or central opioid-like effects. Following oral administration, it is rapidly absorbed and displays favorable pharmacokinetic profile (C_max = 100 nM; T_max = 1.2 h at 1 mg/kg in mice).
