Summary

Cyclosporine A is a cyclic undecapeptide immunosuppressant used to prevent organ transplant rejection and treat autoimmune conditions; it acts via calcineurin inhibition.

Mechanism of Action

Binds cyclophilin, forming a complex that inhibits calcineurin phosphatase activity, suppressing IL‑2 transcription and T‑cell activation
