| 摘要 |
<p>The present invention is related to single-chain insulin having insulin activity comprising a B- and an A-chain or a modified B- and A-chain connected by a connecting peptide of from 6-11 amino acids. The single-chain insulins will have biological insulin activity and an IGF-1 receptor affinity similar to or lower than that of human insulin and a high physical stability. The single-chain insulin may contain at least one basic amino acid residues in the connecting peptide. The single-chain insulins may also be acylated in one or more Lys residues.</p> |
