RhCl3-CATALYZED DISULFIDE EXCHANGE REACTION OF INSULIN AND DITHIODIGLYCOLIC ACID

摘要

RhCl3 catalyzed the alkylthio exchange reaction of insulin and dithiodiglycolic acid in water under homogeneous conditions. Insulin was rapidly consumed, and mono- and bis-exchanged insulin were formed along with the disulfide exchanged A and B chain. The disulfide bond at the A7/B7 was initially exchanged, which was followed by the A6/A11 and A20/B19 disulfides.
