Cyclosporin A is used for immunosuppressive studies .

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.

Cyclosporin A (CsA) blocks T cell activation by interfering with the Ca2+-dependent phosphatase, calcineurin. Proinflammatory responses to bacteria that are activated by Ca2+-fluxes in airway cells are a potential target for CsA. Although local immunosuppression may be advantageous to control...

The effects of cyclosporin A (CY) and cyclophosphamide (CPS) on Peyer's patches (PP) were studied in Wistar rats, exposed in utero and neonatally or during adult age. In one study, pregnant dams received 5 or 15 mg/kg bw/day CY from...

A series of A-ring variously methoxylated 4-(3-hydroxy-4-methoxyphenyl)coumarins related to combretastatin A-4 was prepared by cross-coupling reactions. Cytotoxicity studies indicated a potent activity against HBL100 cell line. Substitution patterns on A-ring had only a slight effect on antiproliferative activity. For most...

Debio-025 is a synthetic cyclosporine with no immunosuppressive capacity but a high inhibitory potency against cyclophilin A (CypA)-associated cis-trans prolyl isomerase (PPIase) activity. A lack of immunosuppressive effects compared to that of cyclosporine was demonstrated both in vitro and in...
