ro9021 is a syk inhibitor.spleen tyrosine kinase (syk) is identified as a critical integrator of intracellular signals regulated by activated immunoreceptors, such as fc receptors and bcell receptors (bcr), which are of great importantance for the function and development of lymphoid cells. | [in vitro]
previous study found that in addition to the suppression of bcell receptor signaling in human peripheral blood mononuclear cells and whole blood, fcγr signaling in human monocytes, and fc r signaling in human mast cells, ro9021 could also block the in vitro osteoclastogenesis from mouse bone marrow macrophages. moreover, the toll-like receptor 9 signaling in human bcells could be blocked by ro9021, leading to the decreased levels of plasmablasts, immunoglobulin (ig) g and igm upon b-cell differentiation. in addition, ro9021 could also potently inhibit type i interferon production by human plasmacytoid dendritic cells (pdc) via tlr9 activation, and such effect was found to be specific to tlr9 since ro9021 did not show inhibitary effect on tlr4- or jak-stat-mediated signaling [1]. | [in vivo]
animal study showed that the oral administration of ro9021could significanly inhibit the arthritis progression in the mcia model, with well observed pharmacokinetics-pharmacodynamic correlation [1]. | [IC 50]
