The present invention relates to insulin derivatives having a side chain attached either to the -amino group of the N-terminal amino acid residue of the B chain or to the amino group of a Lys residue present in the B chain of the parent insulin via an amide bond which side chain comprises at least one aromatic group; at least one free carboxylic acid group or a group which is negatively charged at neutral pH, a fatty acid moiety with 4 to 22 carbon atoms in the carbon chain; and possible linkers which link the individual components in the side chain together via amide bonds.
本发明涉及胰岛素衍生物,其侧链通过酰胺键连接到B链的N-末端氨基酸残基的-氨基基团或存在于亚基中的Lys残基的氨基基团上,该侧链包括至少一个芳香基团;至少一个自由羧酸基团或在中性pH下带有负电荷的基团,一个碳链中含有4至22个碳原子的脂肪酸亚基;以及可能的连接剂,通过酰胺键将侧链中的各个组分连接在一起。
