The present invention provides a compound or a pharmaceutically acceptable salt of the Formula:
X1IVX2SLDVPIGLLQILX3EQEKQEKEKQQAK*TNAX4ILAQV-NH2
wherein the X1 denotes that the I residue is modified by either acetylation or methylation at the N-terminus; wherein X2 is L or T; wherein X3 is L or I; wherein X4 is Q or E; and wherein a modified K residue (“K*”) at position 29 is modified through conjugation to the epsilon-amino group of the K-side chain with a group of the formula —X5—X6, wherein X5 is selected from the group consisting of one to four amino acids; one to four ([2-(2-Amino-ethoxy)-ethoxy]-acetyl) moieties; and combinations of one to four amino acids and one to four ([2-(2-Amino-ethoxy)-ethoxy]-acetyl) moieties; and X6 is a C14-C24 fatty acid. In some embodiments, the group of the formula —X5—X6 is ([2-(2-Amino-ethoxy)-ethoxy]-acetyl)2-(γE)2-CO—(CH2)x—CO2H where x is 16 or 18.
本发明提供了式中的化合物或药学上可接受的盐:
X1IVX2SLDVPIGLLQILX3EQEKEKQAK*TNAX4I
LAQV-NH2
其中 X1 表示 I 残基在 N 端通过乙酰化或甲基化被修饰;其中 X2 是 L 或 T;其中 X3 是 L 或 I;其中 X4 是 Q 或 E;其中位于位置 29 的修饰 K 残基("K*")通过与 K 侧链的ε-
氨基与式 -X5-X6 的基团共轭而被修饰,其中 X5 选自由 1 至 4 个
氨基酸组成的组;一至四个([2-(2-
氨基-乙氧基)-乙氧基]-乙酰基)分子;以及一至四个
氨基酸和一至四个([2-(2-
氨基-乙氧基)-乙氧基]-乙酰基)分子的组合;以及 X6 是 C14-C24
脂肪酸。在某些实施方案中,式-X5-X6 的基团是([2-(2-
氨基-乙氧基)-乙氧基]-乙酰基)2-(γE)2-CO-(
CH2)x-CO2H 其中 x 是 16 或 18。
