Cyclosporin and azathioprine are immunosuppressive drugs, used widely in kidney transplant patients. A significant association between immunosuppressive therapy and multiple warts was described several years ago. There are also some reports of sebaceous gland hyperplasia in kidney transplant patients receiving cyclosporin. We report herein a 57-year-old woman who developed multiple warts on her...

The Raman spectrum of cyclosporin-A has been recorded in the solid phase. The conformation of the molecule has been discussed on the basis of Raman data. It has been concluded that in agreement with X-ray data, cyclosporin-A molecule has an antiparallel P- pleated sheet conformation. It may have some reverse P- turn structure in what has been assigned to a random coil conformation.

The major side effect of cyclosporin A is severe nephrotoxicity. It is likely that cyclosporin A causes vasoconstriction leading to hypoxia-reperfusion injury; therefore, these experiments were designed to attempt to obtain physical evidence for hypoxia and free radical production in kidney following cyclosporin A. Rats were treated daily with cyclosporin A (25 mg/kg ig) for 5 days, and pimonid...

In a growing number of laboratories the technique of liquid chromatography-tandem mass spectrometry is used for the quantification of cyclosporin A in whole blood, employing cyclosporin D as the internal standard. Cyclosporin A is extensively metabolized in vivo; in liquid chromatography-tandem mass spectrometry respective metabolites can give rise to both parent and product ions that are isoba...

UNLABELLED The widely used immunosuppressant cyclosporin A, a potent calcineurin inhibitor, significantly increases the incidence of cancer in organ transplant patients. Calcineurin signaling is an important mediator of VEGF signaling in endothelial cells. Negative regulation of calcineurin by its endogenous inhibitor, Down Syndrome Candidate Region-1 (DSCR1), suppresses tumor growth and angiog...

microemulsion formulation of cyclosporin a (csa) in autoimmune hepatitis (aih)

Stearic acid nanoparticles were prepared in this study by melt-homogenization to investigate the possibility of them as a new kind of drug carrier system. Some physicochemical properties of stearic acid nanoparticles were studied and morphology examined by transmission electron microscope. Cyclosporin A as a model drug was then encapsulated into stearic acid nanoparticles. Following the establi...

background: recently grapefruit juice is known to enhance the bioavailability of several clinically important drugs such as nifedipine, terfenadine, cyclosporine, ethinylestradiole, midazolam, and triazolam. cyclosporine is an immunosuppressive agent that used in transplantation for preventation of chronic rejection. grapefruit increase in cmax and auc of drug mediated by suppression of cyp3a4 ...

Recent studies have shown that cyclosporin A (CsA) may affect ricin A-chain immunotoxin (RTA-IT) therapy. In this study, we evaluated the ability of CsA and its nonirnmunosuppressive analog. SDZ PSC 833, to enhance anti-CD5 T l O l RTA-ITS in vitro. Both 4 pmol/L CsA and 4 pmol/L SDZ PSC 833 significantly and specifically enhanced the cytotoxic activity of T101 RTA-IT on the human lymphoblastic...
