Description
PF 956980 is a JAK3 inhibitor and close analogue of CP 690550 / tofacitinib (Axon 1338). It is used as a tool compound to study JAK3 inhibition in cytokine-dependent immune signaling pathways.
JAK3 associates with the common γ-chain cytokine receptor family and is central to lymphocyte development and immune-cell activation. PF 956980 is relevant for inflammatory disease research, including asthma, COPD and rheumatoid arthritis models.
Key Features
- JAK3 kinase inhibitor
- Close analogue of tofacitinib
- Modulates cytokine receptor-associated immune signaling
- Useful for inflammatory disease pathway studies
Applications
- JAK3 kinase assays
- Cytokine signaling research
- T cell and lymphocyte activation studies
- Asthma, COPD and rheumatoid arthritis model profiling
