Tofacitinib is a potent, selective inhibitor of the JAK family. In human cells, tofacitinib preferentially inhibits signalling by heterodimeric cytokine receptors that associate with JAK3 and/or JAK1. Inhibition of JAK1 and JAK3 by tofacitinib attenuates signalling of interleukins and type I and type II interferons, which will result in modulation of the immune and inflammatory response.
