General description

A potent inhibitor of Janus Protein tyrosine Kinases (JAKs). Displays potent inhibitory activity against JAK1 (IC50 = 15 nM for murine JAK1), JAK2 IC50 = 1 nM), JAK3 (Ki = 5 nM), and Tyk2 (IC50 = 1 nM). It inhibits other kinases only at much higher concentrations. Also inhibits IL-2- and IL-4-dependent proliferation of CTLL cells and blocks the phosphorylation of STAT5.

Biochem/physiol Actions

Cell permeable: yes
Primary Target
murine JAK1
Product competes with ATP.
Reversible: yes
Target IC50: 15 nM, 1 nM against murine JAK1 and JAK2, respectively; 1 nM against Tyk2
Target Ki: 5 nM against JAK3

Packaging

Packaged under inert gas

Warning

Toxicity: Irritant (B)

Physical form

A 10 mM (500 µg/162 µl) solution of JAK Inhibitor I (Cat. No. 420099) in DMSO.

Reconstitution

Following initial use, aliquot and refrigerate (4°C).

Synthetic cytokine receptors can modulate cellular functions based on an artificial ligand to avoid off-target and/or unspecific effects. However, ligands that can modulate receptor activity so far have not been used clinically because of unknown toxicity and immunity against the

Interleukin (IL)-7 is an essential nonredundant cytokine, and throughout the lifespan of a T-cell signaling via the IL-7 receptor influences cell survival, proliferation and differentiation. It is therefore no surprise that expression of the IL-7 receptor alpha-chain (CD127) is tightly

Signalling downstream of Activin/Nodal (ActA) and Wnt can induce endoderm differentiation and also support self-renewal in pluripotent cells. Here we find that these apparently contradictory activities are fine-tuned by insulin. In the absence of insulin, the combination of these cytokines
