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

The development of therapies and vaccines for human hepatropic pathogens requires robust model systems that enable the study of host-pathogen interactions. However, in vitro liver models of infection typically use either hepatoma cell lines that exhibit aberrant physiology or primary

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
