Description générale

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

Actions biochimiques/physiologiques

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.

Preformulation studies on tofacitinib citrate, a small molecule JAK3 specific inhibitor, have not been previously reported in literature. We therefore conducted several preformulation studies on tofacitinib citrate, and its free base, to better understand factors that affect its solubility, stability

Rational new strategies are needed to treat tumors resistant to kinase inhibitors. Mechanistic studies of resistance provide fertile ground for development of new approaches. Cancer drug addiction is a paradoxical resistance phenomenon, well-described in MEK-ERK-driven solid tumors, in which drug-target
