  • Mini-proinsulin, its preparation and use
    Patent number: 6875589
    Abstract: A mini-proinsulin, in which the amino acid Arg bridges the A and the B chain instead of the C chain, shows insulin activity and is suitable for the preparation of pharmaceuticals for the treatment of diabetes mellitus. It can furthermore be converted into an insulin derivative simply using trypsin, the B chain of which is lengthened by Arg. This can be converted into insulin using carboxypeptidase B. Advantageously, however, the mini-proinsulin can also be converted to insulin directly in a one-pot process.
