The invention relates to a derivative of a GLP-1 analogue, which analogue comprises a first K residue and a second K residue, at positions corresponding to position 26, and 37, respectively, of GLP-1(7-37) (SEQ ID NO: 1), and a maximum of eight amino acid changes as compared to GLP-1(7-37); which derivative comprises two protracting moieties attached to said first and second K residue, respectively, via a linker, wherein the protracting moiety is selected from Chem. 1: HOOC—(CH2)x—CO—*, and Chem. 2: HOOC—C6H4—O—(CH2)y—CO—*, in which x is an integer in the range of 8-16, and y is an integer in the range of 6-13; and the linker comprises Chem. 3: *—NH—(CH2)q—CH[(CH2)w—NR1R2]—CO—*, which is connected at its CO—* end to the epsilon amino group of the first or the second K residue of the GLP-1 analogue, and wherein q is an integer in the range of 0-5, R1 and R2 independently represent *—H or *—CH3, and w is an integer in the range of 0-5; or a pharmaceutically acceptable salt, amide, or ester thereof.
The invention also relates to the pharmaceutical use thereof, for example in the treatment and/or prevention of all forms of diabetes and related diseases, as well as to corresponding novel peptide and linker intermediates. The derivatives are potent, stable, protracted, and suitable for oral administration.
本发明涉及一种 GLP-1 类似物的衍
生物,该类似物包括一个第一 K 残基和一个第二 K 残基,分别位于与 GLP-1(7-37)(
