Synthesis of protected decapeptide (B21--30) of human insulin. 1978

V K Naithani, and J Föhles

The synthesis of the C-terminal decapeptide derivative B21--30 of the B-chain of human insulin (benzyloxycarbonyl-gamma-t-butoxyglutamyl-arginyl-glycyl-phenylalanyl-phenylalanyl-O-t-butyltyrosyl-O-t-butylthreonyl-prolyl-Nepsilon-t-butyl-oxycarbonyllysyl-O-t-butylthreonine t-butyl ester, (XIII) by the fragment condensation of the tripeptide B21--23 with the heptapeptide B24--30 is described. Two new routes for both the tripeptide and the heptapeptide were established. A simplified method for the purification of O-t-butylthreonine t-butyl ester was developed.

UI	MeSH Term	Description	Entries
D007328	Insulin	A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).
