Compositions Comprising Glucagon Analogs And Methods Of Making And Using The Same

摘要

This invention relates to novel compositions comprising analogs of glucagon, wherein the analog comprises an α-amino acid and at least one β-amino acid. Administration of the compositions may be used for effecting treatment or prevention of a plurality of disease states caused by dysfunctional biochemical or biological pathways, including diabetes and other metabolic disorders. The compositions and methods of this invention are particularly useful to identify novel therapeutic modulators of in-vivo receptor activity with extended half-lives and relevant bioactivity as compared to the naturally translated polypeptides upon which the analogs are derived.

1. A composition comprising a glucagon analog, wherein said analog comprises a formula of sequential α-amino acids (α) and at least one β-amino acid (β) chosen from: ααααααβ, αααααβα, ααααβαα, αααβααα, ααβαααα, αβααααα, βαααααα, αααααββ, ααααββα, αααββαα, ααββααα, αββαααα, ββααααα, βαααααβ, βααααβα, βαααβαα, βααβααα, βαβαααα, αβααααβ, αβαααβα, αβααβαα, αβαβααα, ααβαααβ, ααβααβα, ααβαβαα, αααβααβ, αααβαβα, and ααααβαβ, wherein the analog is a fusion polypeptide comprising a first and a second amino acid sequence, and wherein the first amino acid sequence is derived from a glucagon amino acid sequence and the second amino acid sequence is derived from glucagon-like peptide-1 (GLP-1).
