fostamatinib disodium
View Patient InformationAn orally available disodium salt of the Syk kinase inhibitor fostamatinib with potential anti-inflammatory and immunomodulating activities. Fostamatinib inhibits Syk kinase-mediated IgG Fc gamma receptor signaling, resulting in inhibition of the activation of mast cells, macrophages, and B-cells and related inflammatory responses and tissue damage.
Syk kinase, widely expressed in hematopoietic cells, is a nonreceptor tyrosine kinase that is involved in coupling activated immunoreceptors to signal downstream events that mediate diverse cellular responses, including proliferation, differentiation, and phagocytosis.
