Semaglutide is a once-daily glucagon-like peptide-1 analog that differs to others by the presence of an acyl group with a steric diacid at Lys26 and a large synthetic spacer and modified by the presence of a α-aminobutyric acid in position 8 which gives stability against the dipeptidylpeptidase-4. It was developed by the Danish pharmaceutical company Novo Nordisk and FDA approved on December 5, 2017.
From the structure above,we can see PEG motif(AEEA-AEEA).Because ester protected AEEA is unstable, we usually provide AEEA as acid motif. AEEA-AEEA unit is quite importment, it will bind with albumin in sub-nano mole affinity,which is 500 fold increase from fatty acid alone.
SINOPEG is pleased to offer this C-18 fatty acid for your R&D and clinic research.
