英文名称 Fostamatinib (R788)
生化机理 R788 (Fostamatinib) is an important spleen tyrosine kinase (Syk) inhibitor, showing efficacy against kinase-mediated IgG Fc gamma receptor signaling. R788 inhibits the activation of mast cells, macrophages, and B-cells and related inflammatory responses and tissue damage. In one study, inhibition of BCR signaling with R788 affected the growth of certain leukemia cell lines. These leukemia cells express stereotyped BCRs that react with auto-antigens exposed on the surface of senescent or apoptotic cells, sμggesting that they are antigen driven.
