Description

OXSI-2 is a bioavailable, cell-permeable Syk inhibitor with an EC50 of 313 nM and an IC50 of 14 nM[1][2].

In Vitro

OXSI-2 (2 μM) completely inhibits Convulxin-induced platelet aggregation and shape change. OXSI-2 (2 μM) also completely blocks GPVI-mediated dense granule release. OXSI-2 (100 nM) does not affect the platelet functional responses induced by Convulxin, and modest shape change is still evident at 1 μM[1].
Adaptor protein LAT is a known substrate of Syk Kinase. OXSI-2 completely inhibits LAT Y191 phosphorylation. OXSI-2 inhibits Syk mediated events in platelets[1].
OXSI-2 (2 μM) inhibits inflammasome assembly, caspase-1 activation, IL-1β processing and release, mitochondrial ROS generation, and pyroptotic cell death[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
