Factor B-IN-8

Factor B-IN-8 (Compound (3R ,4R )-15) is a potent, selective and orally active factor B inhibitor with an IC₅₀ of 10.2 nM. Factor B-IN-8 can effectively inhibit the binding of factor B to C3b and the subsequent formation of C3 convertase (C3bBb). Factor B-IN-8 can inhibit the deposition of membrane attack complex (MAC) mediated by alternativepathway with an IC₅₀ of 59.3 nM. Factor B-IN-8 can reduce the cleavage of factor B protein and decrease the deposition of complement C3d in the glomeruli and renal tubules. Factor B-IN-8 can be used for researches of arthritis and paroxysmal nocturnal hemoglobinuria (PNH).

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
