Janex-1 is a cell-permeable, reversible, potent, ATP-competitive, and specific inhibitor of JAK3 (Janus family kinase 3; IC50 = 78 μM). Janex-1 has no effect on JAK1, JAK2, or Zap/Syk or SRC tyrosine kinases. Janex-1 acts as a potent inhibitor of glioblastoma cell adhesion and migration and is also reported to block thrombin-induced platelet aggregation.
