Nom du produit

STAT3 Inhibitor V, Stattic, STAT3 Inhibitor V, Stattic, CAS 19983-44-9, is a cell-permeable inhibitor of STAT3 cellular function that targets the STAT3-SH2 domain and prevents its association with upstream Kinases.

General description

A cell-permeable vinyl-sulfone compound that acts as an inhibitor of STAT3 cellular function by targeting the STAT3-SH2 domain and preventing its association with upstream kinases. The effect of Stattic towards STAT family members is temperature-dependent and appears to be highly STAT3-selective at 37°C. Shown to inhibit cellular phosphorylation of STAT3 at Tyr705 with little effect towards STAT1 phosphorylation at Tyr701 (in HepG2 cells) or the phosphorylation of JAK1, JAK2, and c-Src (in MDA-MB-231 and MDA-MB-235S cells).

Preparation Note

Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 1 month at -20°C. Note: The use of freshly opened DMSO strongly recommended; the thiol impurities present in DMSO will modify the molecule. Highly recommended to reconstitute just before each use.

Inflammasome activation is of central importance for the process of generation of overwhelming inflammatory response and the pathogenesis of sepsis. The intrinsic molecular mechanism for controlling inflammasome activation is still poorly understood. Here we investigated the role of p120-catenin expression

Pathways and Biomarkers of JAK/STAT Signaling

Pathways and Biomarkers of JAK/STAT Signaling

JAK/STAT Signaling Research Focus

The Janus kinase (JAK)/signal transducers and activators of transcription (STAT) signaling pathway plays an important role in cell proliferation, cell differentiation, cell migration, and cell death. It is the principal signaling mechanism for a variety of cytokines and growth factors. Constitutive activation or dysregulation of JAK/STAT signaling can result in inflammatory disease, erythrocytosis, gigantism, and leukemia.
