jak3 in 11

JAK3-IN-11 (Compound 12) exhibits potent, noncytotoxic, irreversible, orally active JAK3 inhibitory activity (IC50 = 1.7 nM) with an excellent selectivity profile (>588-fold compared to other JAK isoforms), covalently binds to the ATP-binding pocket in JAK3. JAK3-IN-11 strongly inhibits JAK3-dependent signaling and T-cell proliferation which is a promising tool for studying autoimmune diseases [1].

JAK-IN-39 (compound 11) is a JAK inhibitor with IC50 values of 0.05 nM for JAK1, 1.18 nM for JAK2, and 0.03 nM for JAK3. It reduces cell viability in TF-1 cells and inhibits the production of TNFα and INFγ in lymphocytes in vitro.

Decernotinib (VRT-831509)(VX-509; VRT-831509) is a potent and selective Janus kinase 3 (JAK3) inhibitor with Ki of 2.5 nM; IC50 is 50-170 nM in cellular assays.
