Abstract
The invention relates to GLP-1 analogues and derivatives having a Trp at a position corresponding to position 8 of GLP-1(7-37), and their pharmaceutical use e.g. in the treatment of type 2 diabetes. These Trp8 compounds are very stable against degradation by DPP-IV, while maintaining the capability to bind to and activate the GLP-1 receptor. The derivatives have one or two substituents (P-L) attached to a Lys residue of the GLP-1 analogue via an optional Branching group (B), wherein P is a Protracting moiety such as a fatty diacid, and L is a linker consisting of one or more linker elements such as, for example, 8-amino-3,6-dioxaoctanoic acid. Examples of compounds of the invention include the 8W variants of liraglutide and dulaglutide. The invention also relates to a method for the fully recombinant preparation of 8W GLP-1 analogues and derivatives which is more simple and thereby cheaper as compared to the preparation of known GLP-1 analogues that have been DPP-IV stabilised by inclusion of one or more non-coded amino acids.
