Cyclosporin A: A Calcineurin Inhibitor with Immunosuppressive Properties

Cyclosporin A (CsA) is a cyclic polypeptide immunosuppressant, and was initially isolated from the fungus Tolypocladium inflatum Gams in 1970. Cyclosporin A is practically insoluble in water, soluble in diethyl ether, and very soluble in methanol, ethanol and acetonitrile. Cyclosporin A inhibits T-lymphocyte activation, although the exact mechanism of action is not known. Experimental evidence suggests that cyclosporin A is inactive by itself and requires binding to an intracellular protein, cyclophiline D (CypD), for activation in cells. A complex of CsA–CypD, calcium, calmodulin, and calcineurin (a calcium and calmodulin dependent protein phosphatase) is then formed and the phosphatase activity of calcineurin inhibited. This effect may prevent both T-lymphocyte signal transduction and IL-2 transcription. Tacrolimus (FK506) [M2258] is also inhibits calcineurin and is more potent than cyclosporin A. Cyclosporin A is mainly metabolized by cytochrome P 450 IIIA (CYP3A) subfamilies. (The product is for research purpose only.)
