FD-IN-1

FD-IN-1 (Compound 12) exhibits functional inhibition of AP activation (IC ₅₀ =0.26 μM) in vitro in a membrane attack complex (MAC) deposition assay using 50% human whole blood (WB).

FD-IN-1 (Compound 12) demonstrates systemic suppression of AP activation in a lipopolysaccharide-induced alternative complement pathway (AP) activation model as well as local ocular suppression in intravitreal injection-induced AP activation model in mice expressing human FD.
FD-IN-1 (Compound 12) exhibits high oral bioavailability (C57BL6 mice 83%, Beagle dogs 70%) following oral administration (mice and dogs 10 mg/kg).
FD -IN-1 (Compound 12) exhibits terminal elimination half-lives (C57BL6 mice 1.6 h and Beagle dogs 3.8 h) following intravenous administration (mice and dogs 1 mg/kg).
