Semaglutide

Description of Semaglutide

Semaglutide is a recombinant human glucagon-like peptide-1 (GLP-1) analogue, belonging to the class of GLP-1 receptor agonists (or GLP-1 RAs). Novo Nordisk developed three formulations of semaglutide already available in the market: Ozempic and Wegovy (injection formulation) and Rybelsus (oral tablet).

Ozempic and Rybelsus are indicated for glycemic control in type 2 diabetes mellitus patients, while Wegovy is for weight management in obesity or overweight patients.

Amino Acid Sequence of Semaglutide

Semaglutide is a well-designed long-acting GLP-1 (7-37) analogue based on liraglutide. Semaglutide differs from liraglutide in two sites. Position 8 is replaced by Aib(U)——a modification that significantly protects it from enzymatic degradation by the dipeptidyl-peptidase 4 (DPP-4). In addition, the modified fatty acid chain and two PEG2 intermediates are optimal for prolonged efficacy both in vitro and in vivo.
