Abstract
A single-chain insulin analogue comprises a B-chain insulin polypeptide connected to an A-chain insulin polypeptide by a C-domain polypeptide. The B-chain insulin polypeptide contains a Cysteine substitution at position B4. The A-chain insulin polypeptide contains a Cysteine substitution at position A10. The C-domain polypeptide is 4 to 11 amino acids long. The analogue mitigates the unfavorable activity of this 4th disulfide bridge in conventional two-chain insulin analogues resulting in a duration of insulin signaling similar to that of wild-type insulin. A method of treating a patient with diabetes mellitus comprises the administration of a physiologically effective amount of the protein or a physiologically acceptable salt thereof to a patient. Use of a single-chain insulin analogue of the present invention in an insulin delivery device (such as a pump or pen) or as part of a high-temperature polymer-melt manufacturing process.
