Description
FD-IN-1 (Compound 12) is an orally bioavailable and selective factor D (FD) inhibitor with an IC50 of 12 nM. Complement FD, a highly specific S1 serine protease, plays a central role in the alternative complement pathway of the innate immune system. FD-IN-1 also inhibits factor XIa (FXIa) and Tryptase β2 with IC50s of 7.7 and 6.5 µM, respectively.

How to use
In Vitro:
FD-IN-1 (Compound 12) exhibits functional inhibition of AP activation (IC50=0.26 μM) in vitro in a membrane attack complex (MAC) deposition assay using 50% human whole blood (WB).
In Vivo:
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).
