Ruxolitinib (INCB018424) is a JAK1/2 inhibitor (IC50=3.3/2.8 nM) that is potent and selective. Rixolitinib exhibits antitumor activity and induces autophagy and apoptosis.

Gusacitinib (ASN-002) (ASN-002) is spleen tyrosine kinase (SYK) and janus kinase (JAK) inhibitor (IC50: 5-46 nM).

Deucravacitinib is a highly selective, orally bioavailable, allosteric TYK2 inhibitor for the treatment of autoimmune diseases. It blocks receptor-mediated Tyk2 activation by stabilizing the regulatory JH2 domain, inhibiting IL-12/23 and type I IFN pathways. It selectively binds to the TYK2 pseudokinase (JH2) domain with an IC50 of 1.0 nM.

Fedratinib (TG-101348) (TG101348) is an ATP-competitive inhibitor of JAK2 (IC50: 3 nM) with significantly less potent activity against JAK3.

Baricitinib (INCB028050) is a JAK1 and JAK2 inhibitor (IC50=5.9/5.7 nM) with selective and oral activity. Baricitinib has potential anti-inflammatory, immunomodulatory and anti-tumor activity.

Ruxolitinib phosphate (INCB18424 phosphate) is a JAK1/2 inhibitor with IC50 of 3.3 nM/2.8 nM. Its selectivity for JAK1/2 is more than 130 times that of JAK3.

Itacitinib (INCB039110) is an orally bioavailable Janus-associated kinase 1 (JAK1) inhibitor with potential antineoplastic activity.

Tofacitinib (Tasocitinib) is a Janus kinase inhibitor that inhibits JAK3/2/1 (IC50=1/20/112 nM) and is orally active. Tofacitinib is used for the treatment of moderate to severe rheumatoid arthritis.

Upadacitinib (ABT-494) is a highly potent, selective, and orally active JAK1 inhibitor with an IC₅₀ of 43 nM; its selectivity for JAK1 is approximately 74 times that for JAK2. Upadacitinib is being investigated for the treatment of autoimmune diseases such as rheumatoid arthritis and ankylosing spondylitis.

Abrocitinib (PF-04965842) (PF-04965842) is a potent, specific and orally-active JAK1 inhibitor (IC50s: 29/803 nM for JAK1/2).

JAK-IN-5 is a JAK inhibitor.

FLLL32 is an effective JAK2/STAT3 inhibitor (IC50 of <5 μM).

Tofacitinib Citrate (CP-690550 citrate) is a a potent, cell-permeable inhibitor of JAK1/2/3 (IC50s: 1/20/112 nM).

Ilginatinib maleate (NS-018 maleate) is a highly active, orally bioavailable inhibitor of JAK2.

RO495 (CS-2667), a potent inhibitor of TYK2, inhibits TYK2 with IC50 of 1.5nM as tested in cell-based pharmacological assays

Povorcitinib phosphate is a selective JAK1 inhibitor and can be used in studies about the treatment of cutaneous lupus erythematosus and Lichen planus.

Golidocitinib (AZD4205) is a selective JAK1 inhibitor with an IC50 of 73 nM, while it weakly inhibits JAK2 and JAK3 with IC50 values greater than 14.7 μM and 30 μM, respectively.

Ilginatinib (NS-018) is a highly active, orally bioavailable JAK2 inhibitor.

Ilginatinib hydrochloride (NS-018 hydrochloride) is a highly active, orally bioavailable JAK2 inhibitor.

Brepocitinib P-Tosylate (PF-06700841 P-Tosylate) is a potent dual inhibitor of Janus kinase 1 (JAK1) and TYK2 (IC50s of 17 nM and 23 nM, respectively).

Delgocitinib (JTE-052) is a JAK inhibitor and a specific JAK1/2/3/Tyk2 inhibitor (IC50=2.6-58 nM) that blocks multiple cytokine signaling pathways and inhibits pruritus, used for research on inflammatory and autoimmune diseases.

TCS 21311 (NIBR3049) is an effective and highly selective inhibitor of JAK3 (IC50: 8 nM). TCS 21311 inhibits PKCα, PKCθ, and GSK3β (IC50s: 13, 68, and 3 nM, respectively). It displays >100-fold selectivity over JAK1, JAK2, and TYK2.

Momelotinib (LM-1149) is an orally bioavailable small-molecule inhibitor of Janus kinases 1 and 2 (JAK1/2) with IC50 of 11 nM/18 nM. JAK1/2 inhibitor CYT387 competes with JAK1/2 for ATP binding, which may result in inhibition of JAK1/2 activation, inhibition of the JAK-STAT signaling pathway, and so the induction of apoptosis and a reduction of tumor cell proliferation in JAK1/2-expressing tumor cells.

Filgotinib (GLPG0634) is a selective JAK1 inhibitor with IC50 values of 10 nM for JAK1, 28 nM for JAK2, 810 nM for JAK3, and 116 nM for TYK2.
