Biological Activity
Cyclosporin A is an immunosuppressant which binds to the cyclophilin and inhibits phosphatase activity of calcineurin with an IC50 of 5 nM.
In Vitro
Cyclosporin A is able to bind with the cyclophilin in T cells[1]. Cyclosporin A works by forming a Cyclophilin-Cyclosporin A complex to inhibit calcineurin[2]. Cyclosporin A exhibits inhibitory effect on calcineurin with an IC50 of 7 nM[3]. Cyclosporin A suppresses the nuclear translocation of NF-AT[4]. Cyclosporin A shows an effect on mitochondria via preventing the MTP from opening with an IC50 of 39 nM[5].
In Vivo
Cyclosporin A has immunosuppressive activity, and is active via parenteral and p.o. administration in mice, rat and guinea pigs[6]. Cyclosporin A can be used in organ transplantation to prevent rejection[7].
