complement factor d in 1

Complement factor D-IN-1 is a potent and selective small-molecule reversible Factor D inhibitor, with IC50 values of 0.006 μM in the FD Thioesterolytic Fluorescent Assay and 0.05 μM in the MAC Deposition Assay.

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

N-((Allyloxy)carbonyl)-N-methyl-L-alanine, an alanine derivative, serves as a precursor for synthesizing complement factor D inhibitors, which are essential for researching immune system-related diseases [1].
