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.

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

Deucravacitinib (BMS-986165) 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.

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.

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.

RO8191 (CDM-3008) (CDM-3008) is an agonist of interferon (IFN) receptor.

CEP-33779 is a novel and selective inhibitor of JAK2 with an IC50 of 1.8±0.6 nM.

WHI-P97 is a rationally designed potent inhibitor of JAK-3. IC50 value: Target: JAK3 Treatment of mast cells with WHI-P97 inhibited the translocation of 5-lipoxygenase (5-LO) from the nucleoplasm to the nuclear membrane and consequently 5-LO-dependent leukotriene (LT) synthesis after IgE receptor/FcepsilonRI crosslinking by >90% at low micromolar concentrations. WHI-P97 did not directly inhibit the enzymatic activity of 5-LO, but prevented its translocation to the nuclear membrane without affecting the requisite calcium signal.
