Application Notes

Isocyclosporin A is a rearranged degradation product formed by acid treatment of cyclosporin A under aqueous and non-aqueous conditions. This rearrangement has been used as the basis of a HPLC fluorescence for quantifying cyclosporin A. The pharmacology of isocyclosporin A has received little attention.
