Cyclosporin A
Description
Cyclosporin A (CsA) is a cyclic undecapeptide from an extract of soil fungi that binds the cyclophilin D and thus preventing the formation of the mitochondrial permeability transition pore. The interaction of CsA with the cyclophilin D is phosphate mediated but the full mechanism of interaction is not well understood. For example, the deficiency of cyclophilin D in KO models does not prevent mitochondria from permeability transition and from CsA inhibition. Moreover, it is also a is a calcineurin inhibitor and potent immunosuppressive agent used largely as a means of prophylaxis against cellular rejection after solid organ transplantation.
