| Biochem/physiol Actions: | A fungal metabolite possessing potent immunosuppressive properties. It inhibits the T-cell receptor signal transduction pathway via the formation of cyclosporin A−cyclophilin complex that inhibits calcineurin (protein phosphatase 2B). Inhibits nitric oxide synthesis induced by interleukin 1α, lipopolysaccharides and TNFα. Can block cytochrome c release from mitochondria. |
