The present invention relates to protracted human insulin derivatives in which the A21 and the B3 amino acid residues are, independently, any amino acid residue which can be coded for by the genetic code except Lys, Arg and Cys; PheB1 may be deleted; the B30 amino acid residue is
a) a non-codable, lipophilic amino acid having from 10 to 24 carbon atoms, in which case an acyl group of a carboxylic acid with up to 5 carbon atoms is bound to the ∈-amino group of Lys829; or
b) the B30 amino acid residue is deleted or is any amino acid residue which can be coded-for by the genetic code except Lys, Arg and Cys, in any of which cases the ∈-amino group of LysB29 has a lipophilic substituent;
and any Zn2+ complexes thereof with the proviso that when B30 is Thr or Ala and A21 and B3 are both Asn, and PheB1 is present, then the insulin derivative is always present as a Zn2+ complex.
本发明涉及持久人胰岛素衍生物,其中的 A21 和 B3 氨基酸残基分别是除 Lys、Arg 和 Cys 以外的任何可由遗传密码编码的氨基酸残基;PheB1 可被删除;B30 氨基酸残基是
a) 具有 10 至 24 个碳原子的不可编码的亲脂性氨基酸,在这种情况下,具有最多 5 个碳原子的羧酸酰基与 Lys829 的∈-氨基结合;或
b) B30 氨基酸残基被删除或为除 Lys、Arg 和 Cys 以外的任何可被遗传密码编码的氨基酸残基,在上述任何一种情况下,LysB29 的∈-氨基具有亲脂取代基;
及其任何 Zn2+ 复合物,但条件是当 B30 为 Thr 或 Ala,A21 和 B3 均为 Asn,且存在 PheB1 时,胰岛素衍生物总是作为 Zn2+ 复合物存在。
