✦ Synopsis
Enhancement of Detection Sensitivity of Cyclosporin A by Derivatization with 2‐Napthylselenylchloride
The UV./HPLC. detection sensitivity of cyclosporine A 1, an immunosuppressive cyclic undecapeptide containing one D‐aminoacid and seven N‐methylated aminoacids, is enhanced by a factor of 3‐4 (limit of detection 5 ng) by conversion of the characteristic side chain of amino‐acid‐1 to the β‐naphthylseleno‐substituted tetrahydrofuran derivative 4.
