Glucagon-like peptide-1 analogues and uses thereof
Provided is a glucagon-like peptide-1 (GLP-1) analog shown as the following formula, wherein X is selected from glycine and glycinamide. The GLP-1 analog has a non-proteogenic amino acid residue in position 8 relative to the sequence GLP-1, and is acylated with a moiety comprising two acidic groups to the lysine residue in position 26. The GLP-1 analog is resistant to dipeptidyl peptidase IV so as to have an extended half-life in vivo. Also provided is a use of the GLP-1 analog in conquering blood sugar.

or a pharmaceutically acceptable salt thereof, wherein X is glycine or glycinamide.
2. A pharmaceutical composition comprising a therapeutically effective amount of at least one compound of claim 1 and at least one pharmaceutically acceptable excipient.
3. A method of modulating the blood glucose level in a subject in need thereof comprising administering to the subject a compound of claim 1 .
4. A method for treating a disease, disorder, or condition in a subject thereof, comprising administering to the subject in need thereof a therapeutically effective amount of a compound of claim 1 , wherein the disease, disorder, or condition is type diabetes, impaired glucose tolerance, type I diabetes, obesity, hypertension, or syndrome X.
5. A method for treating or delaying a disease, disorder, or condition in a subject thereof; comprising administering to the subject in need thereof a therapeutically effective amount of a compound of claim 1 , wherein the disease, disorder, or condition is type II diabetes.
6.
