JAK/Stat - JAK3

CYT387 sulfate salt is an ATP-competitive inhibitor of JAK1/JAK2 with IC50 of 11 nM/18 nM, ~10-fold selectivity versus JAK3.

Janex-1 is a cell-permeable, reversible, potent, ATP-competitive, and specific inhibitor of JAK3 (IC50 = 78 uM); has no effect on JAK1, JAK2, or Zap/Syk or SRC tyrosine kinases.

TCS 21311 is a potent JAK3 inhibitor (IC50 = 8 nM). TCS 21311 is selective for JAK3 over JAK1, JAK2 and Tyk 2 (IC50 values are 1017, 2550 and 8055 nM respectively).

JAK3 Inhibitor V is a potent, selective inhibitor of JAK3 (Janus tyrosine kinase 3) which binds competitively to the JAK3 ATP site.
