Glycosylated insulin derivatives
First Claim
1. A glycosylated insulin having the formula ##STR21## wherein Z and X are different and are selected from the group consisting of -H and -OH, and m is an integer of 1 to 3 and wherein each glycosyl group is attached to the insulin by a thioamide linkage through one or more of the α
- -amino groups of the A-1 glycine, B-1 phenylalanine or ε
-amino group of the B-29 lysine moieties of the insulin molecule.

Abstract
Synthesized succinyl and glutaryl glucosamines, p-(succinylamido)-phenyl-α-D-gluco- and mannopyranosides, p-(glutarylamido)-phenyl-α-D-gluco- and mannopyranosides and p-(isothiocyanotophenyl)-α-D-gluco- and mannopyranosides are reacted with insulin to form corresponding glycosylated insulins containing from 1 to 3 glycosyl groups per insulin molecule. The novel glycosylated insulins resist aggregation and show significant activity in depressing blood sugar levels.
