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]. Western Blot Analysis[1] Cell Line: Aspirin-treated, washed human platelets Concentration: 2 μM Incubation Time: Result: Completely inhibited Syk-mediated LAT Y191 phosphorylation.
