Cyclosporin A is an immunosuppressant that binds to cyclophilin and inhibits calcineurin with an IC50 of 7 nM. cyclosporin A [CsA] binds to the cyclophilin 18 (Cyp18)-CsA complex. the Cyp18-CsA complex recruits calcium-regulated neurophosphatase (CaN), leading to the blocking of cytokine gene transcription in activated T cells. CsA is a highly specific inhibitor of T-cell activation.

Preparation method | Immunosuppressive agents are dissolved in ethanol at concentrations 1000-fold more than the concentration desired for cell treatments. Cells (106) are suspended in 1 ml of complete medium in microcentrifuge tubes; 1 μl of ethanol or of the ethanolic solution of Cyclosporin A is added, and the cells are incubated at 37°C for 1 hr. Cells are washed twice with 1 ml of PBS on ice and lysed in 50μl of hypotonic buffer containing 50 mM Tris (pH 7.5); 0.1 mM EGTA; 1 mM EDTA; 0.5 mM dithiothreitol; and 50 μg of phenylmethylsulfonyl fluoride, 50 μg of soybean trypsin inhibitor, 5 μg of leupeptin, and 5 μg of aprotinin per ml. Lysates are subjected to three cycles of freezing in liquid nitrogen followed by thawing at 30°C and then are centrifuged at 4°C for 10 min at 12,000×g. |

Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
