The invention relates to protracted
Glucagon-Like
Peptide-1 (GLP-1) derivatives and therapeutic uses thereof. The GLP-1 derivative of the invention comprises a modified GLP-1(7-37) sequence having a total of 2-12
amino acid modifications, including Glu22 and Arg26, and being derivatised with an
albumin binding residue or pegylated in position 18, 20, 23, 30, 31, 34, 36, 37, or 39. These compounds are useful in the treatment or prevention of diabetes type 2 and related diseases. The compounds are potent, stable, have long half-lives, a high affinity of binding to
albumin, and / or a high affinity of binding to the
extracellular domain of the GLP-1
receptor (GLP-1R), all of which is of potential relevance for the overall aim of achieving long-acting, stable and active GLP-1 derivatives with a potential for
once weekly administration.
