The present invention relates to tri-acylated GLP-1 derivatives, acylated at positions corresponding to positions (18, 22, 30), (18, 26, 37), (18, 27, 37), (26, 30, 37), or (27, 30, 37) of the native human glucagon-like peptide 1 (GLP-1 (7-37) (SEQ ID NO: 1); or pharmaceutically acceptable salts, amides, or esters thereof. The acylated side chains comprise a protracting moiety selected from Chem. 1: HOOC—(CH

—CO—*, and the protracting moieties are connected, via a linker, to a Lys residue of the GLP-1 peptide. The GLP-1 peptide has a maximum of seven amino acid changes as compared to GLP-1 (7-37) (SEQ ID NO: 1). The invention also relates to intermediate products in the form of novel GLP-1 analogues, as well as to pharmaceutical compositions and uses of the derivatives and analogues, in particular for the treatment of type 2 diabetes. The derivatives have very long half-lives while maintaining a satisfactory potency, which makes them potentially suitable for once-monthly administration.
本发明涉及三酰化GLP-1衍生物,酰化位置与人源胰高血糖素样肽1(GLP-1(7-37)(序列号:1))的位置(18、22、30)、(18、26、37)、(18、27、37)、(26、30、37)或(27、30、37)相对应,并且其药学上可接受的盐、酰胺或酯。酰化侧链包括从化学1: HOOC—(CH2)16—CO—*、化学1a: HOOC—(CH2)18—CO—*和化学2: HO3S—(CH2)15—CO—*中选择的延长基团,并且通过连接器连接到GLP-1肽的一个赖氨酸残基。与GLP-1(7-37)(序列号:1)相比,GLP-1肽最多有七个氨基酸变化。该发明还涉及作为新GLP-1类似物的中间产物,以及衍生物和类似物的药物组合物和用途,特别是用于治疗2型糖尿病。这些衍生物具有非常长的半衰期,同时保持了令人满意的效力,这使它们有可能适合每月一次的给药。
