Iso-Tacrolimus is a macrolide lactone compound that inhibits T-lymphocyte activation and proliferation by binding to the intracellular protein, FKBP-12. This complex inhibits the activity of calcineurin, which is a key enzyme in the production of interleukin-2, a cytokine that promotes the growth and differentiation of T-cells. By inhibiting this pathway, iso-Tacrolimus effectively suppresses the immune response. Iso-Tacrolimus has anti-inflammatory and anti-proliferative effects, making it valuable in the field of immunosuppression.
