Description

General description

Tofacitinib is a synthetic molecule corresponding to a molecular weight of 312.4 Da and is permeable by transcellular diffusion.

Application

Tofacitinib citrate has been used:

• as a ligand for human serum albumin in fluorescence quenching, dynamic light scattering (DLS) measurements, differential scanning calorimetry and molecular docking studies
• as a medium supplement for full depth articular cartilage (FDC) explants to monitor cytokine-induced proteoglycan loss
• as a Janus kinase inhibitor in MCF7 breast cancer cells

Biochem/physiol Actions

Tofacitinib is a potent inhibitor of Janus kinase 3 (JAK3) with some JAK-1 inhibitory activity as well. It blocks downstream STAT signaling resulting in potent inhibition of inflammatory cytokines with resultant immunosuppressive and anti-inflammatory activity. Tofacitinib is being investigated for for several autoimmune disorders including, rheumatoid arthritis, psoriasis and dry eye.
