Biological Activity

Description Baricitinib (LY3009104, INCB028050) is a selective inhibitor of JAK1 and JAK2 with IC50 values of 5.9 nM and 5.7 nM,
Targets JAK2 JAK1 TYK2 JAK3 Chk2 c-Met
IC50 5.7 nM 5.9 nM 53 nM >400 nM >1 μM >10 μM

Protocol

Kinase experiment [1]:

Inhibitory activities

Enzyme assays were performed using a homogeneous time-resolved fluorescence assay with recombinant epitope tagged kinase domains (JAK1, 837-1142; JAK2, 828-1132; JAK3, 718-1124; Tyk2, 873-1187) or fulllength enzyme (cMET and Chk2) and peptide substrate. Each enzyme reaction was performed with or without Baricitinib (LY3009104, INCB028050) (11-point dilution), JAK, cMET, or Chk2 enzyme, 500 nM (100 nM for Chk2) peptide, ATP (at the Km specific for each kinase or 1 mM), and 2.0% DMSO in assay buffer. The calculated IC50 value is the Baricitinib (LY3009104, INCB028050) concentration required for inhibition of 50% of the fluorescent signal. Additional kinase assays were performed at Cerep using standard conditions at 200 nM. Enzymes tested included: Abl, Akt1, AurA, AurB, CDC2, CDK2, CDK4, CHK2, c-kit, EGFR, EphB4, ERK1, ERK2, FLT-1, HER2, IGF1R, IKKa, IKKb, JNK1, Lck, MEK1, p38a, p70S6K, PKA, PKCa, Src, and ZAP70.

Cell experiment [1]:

Cell lines

Human PBMCs; PHA-stimulated T cells.

Preparation method

Soluble in DMSO > 10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reaction Conditions

10, 100, 1000, 10000 nM; 48 h.

Applications

In PBMCs, INCB028050 inhibits STAT3 phosphorylation stimulated by IL-6 and the production of chemokine MCP-1 with IC50 values of 44 and 40 nM, respectively. In isolated naive T-cells, INCB028050 inhibits STAT3 phosphorylation with IC50 value of 20 nM and inhibits the production of IL-17 and IL-22 with IC50 value of 50 nM.

Animal experiment [1]:

Animal models

Female rats; adjuvant-induced arthritis rats; DBA/1j arthritis mice induced by bovine type II collagen.

Dosage form

Female rats: 10 mg/kg; 24 h; oral gavage.Adjuvant-induced arthritis rats: 1, 3, or 10 mg/kg; once daily for 2 wk; administrated orally.Collagen-induced arthritis (CIA) model: 1, 3, or 10 mg/kg; twice daily for 15 d; administrated orally.

Preparation method

Suspended in 0.5% methylcellulose and given by oral gavage at 10 ml/kg.

Applications

In female rats, INCB028050 (10 mg/kg) inhibits JAK1/2 signaling by ≥50% for 8 h. In rat adjuvant-induced arthritis, INCB028050 (1, 3, or 10 mg/kg) reduces disease scores by 24%, 57% and 81% respectively and inhibits the increase of hind paw volumes by 50%, >95% and >95%, respectively. Also, INCB028050 reduced bone resorption. In CIA mice model, INCB028050 (1, 3, or 10 mg/kg) reduces clinical scores by 19%, 67% and 61% respectively and inhibits IL-6 and IL-23 signaling and function.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

Baricitinib, formerly named LY3009104 or INCB028050, is a new selective orally bioavailable inhibitor of tyrosine-protein kinase JAK1 or JAK2. Also, it is an ATP competitive kinase inhibitor. In vitro, it is able to inhibit JAK1 and JAK2 in a low nanomolar range with IC50 values of 5.9 and 5.7 nM, respectively, while it demonstrates low inhibitory activity for JAK3 and moderate activity for TYK2. Baricitinib inhibits intracellular signaling of multiple proinflammatory cytokines including IL-6 and IL-23 at concentrations <50 nM. It should also be recognized that JAK signaling is central to a number of fundamental processes, including the generation of RBCs
