The chemical structure of semaglutide is that of a modified analog of human glucagon-like peptide-1 (GLP-1)作者：AK Rai·被引用次数：3—DESCRIPTION OF STRUCTURAL CLASS​​ Semaglutide, a fatty-acylated GLP-1 analog [Figure 3], (molecular formula: C187H291N45O59, molecular weight: 4113.67 g/mmol) is .... Specifically, it's described as a modified analogue of glucagon-like peptide 1-(7-37). While human GLP-1 is a peptide hormone composed of 30 amino acids, semaglutide features a more complex arrangement. It contains a linear sequence of 31 amino acids joined together by peptide linkages. This extended chain is a fundamental aspect of its design.

A key modification within the semaglutide sequence involves two amino acid substitutions compared to human GLP-1. These critical changes occur at specific positions: amino acids at positions 8 and 34 are replaced. The amino acid at position 8 is substituted with α-aminobutyric acid (Aib), and the amino acid at position 34 is replaced by arginine (Arg)Semaglutide: An expedition on last approved glucagon-like .... This strategic alteration is pivotal in enhancing the molecule's stability and prolonging its half-life in the body.

Functionally, semaglutide acts as a GLP-1 receptor agonistCAS No : 910463-68-2 | Product Name : Semaglutide - API. By mimicking the action of endogenous GLP-1, it binds to and activates GLP-1 receptors. This activation triggers a cascade of beneficial physiological responses, including increased insulin secretion, reduced glucagon secretion, slowed gastric emptying, and enhanced satiety.Semaglutideis a glucagon-like peptide 1 (GLP-1) analogused to manage type 2 diabetes along with lifestyle changes, such as dietary restrictions and increased ... The molecule's ability to penetrate the blood-brain barrier further contributes to its effects on appetite regulation.

Researchers have made detailed observations regarding specific interactions within the semaglutide molecule and its receptor. For instance, studies indicate that at the receptor level, the Tyr19 of Semaglutide forms a hydrogen bond with Glu138 of the receptor and Gln17 of the peptide, while the Glu21 of Semaglutide forms a hydrogen bond with Ser31 of the receptor. These precise molecular interactions are vital for the drug's binding affinity and subsequent pharmacological activity.

The distinction between different forms of the drug is also relevant. While semaglutide is the active pharmaceutical ingredient, salt forms such as semaglutide sodium and semaglutide acetate are also recognized. These salt forms represent different chemical states of the active compound and are distinct from the active ingredients in approved medications.semaglutide | Ligand page

Overall, the chemical structure of semaglutide – a 31 amino acid peptide with specific substitutions and a fatty acid acylation – is a testament to sophisticated medicinal chemistry. This carefully engineered molecular architecture, represented by its complex formula and defined amino acid sequence, underpins its potent glucose-lowering properties and its role as a leading therapeutic agent in metabolic disease management. The detailed understanding of its chemical structure of semaglutide is paramount for continued research and development in this field.
