Overview
Dulaglutide (LY2189265) is a long-acting glucagon-like peptide-1 (GLP-1) receptor agonist developed by Eli Lilly and Company. It was approved by the FDA in September 2014 and is commercially available as Trulicity® for the treatment of type 2 diabetes mellitus .
Unlike traditional GLP-1 analogs, Dulaglutide is a recombinant fusion protein consisting of a GLP-1 analog (residues 7-37) covalently linked to the Fc domain of human IgG4 via a small peptide linker . This innovative design protects the molecule from DPP-4 degradation and enables once-weekly subcutaneous administration, offering superior patient convenience compared to daily GLP-1 agonists .
Our Dulaglutide API is produced under strict cGMP standards with high purity and comprehensive documentation support for research and development purposes.

GLP-1 Analog Sequence (Active Moiety):
H-HGEGTFTSDVSSYLEEQAAKEFIAWLVKGGG-OH
Structure: GLP-1 analog – (Ser₄Gly)₃ linker – human IgG4 Fc (dimer)
Mechanism of Action
Dulaglutide is a potent and selective GLP-1 receptor agonist. GLP-1 is an incretin hormone secreted by intestinal L-cells in response to nutrient ingestion . Key pharmacological effects include:
-
Glucose-dependent insulin secretion – stimulates insulin release from pancreatic β-cells only when blood glucose is elevated
-
Suppressed glucagon secretion – reduces hepatic glucose output
-
Delayed gastric emptying – slows postprandial glucose absorption
-
Appetite regulation – acts on hypothalamic centers to reduce food intake
The IgG4 Fc fusion provides two critical advantages:
-
Extended half-life (~4-5 days) – supports once-weekly dosing
-
Reduced immunogenicity – IgG4 minimizes unwanted immune responses
The molecule naturally forms a covalent dimer stabilized by disulfide bridges, enhancing its stability and receptor binding affinity .
Clinical Applications
Type 2 Diabetes Mellitus
Dulaglutide is indicated for improving glycemic control in adults with type 2 diabetes mellitus as an adjunct to diet and exercise. It is available in 0.75 mg and 1.5 mg once-weekly doses.
Key clinical outcomes from the AWARD program include:
-
Significant HbA1c reduction (1.1-1.6% from baseline)
-
Moderate weight loss (2-3 kg on average)
-
Low risk of hypoglycemia when used as monotherapy
-
Cardiovascular safety profile
Approved Doses
| Indication | Dose | Administration |
| Type 2 Diabetes (initial) | 0.75 mg | Once weekly |
| Type 2 Diabetes (escalated) | 1.5 mg | Once weekly |
Structural Advantages
Dulaglutide's unique molecular design distinguishes it from other GLP-1 agonists:
| Feature | Dulaglutide | Liraglutide | Semaglutide |
| Dosing frequency | Once weekly | Once daily | Once weekly |
| Molecular type | Fc fusion protein | Fatty acid acylated peptide | Fatty acid acylated peptide |
| Half-life | ~4-5 days | ~13 hours | ~7 days |
| Administration | Subcutaneous | Subcutaneous | Subcutaneous/oral |
The Fc fusion approach eliminates the need for chemical modification or fatty acid acylation, providing a more straightforward manufacturing process while maintaining excellent pharmacokinetic properties .
Biosimilar Development
Dulaglutide is an attractive target for biosimilar development due to:
-
Expiring patents – opening markets for generic versions
-
Well-characterized structure – recombinant protein with established production platforms
-
Growing global demand – increasing diabetes prevalence worldwide
Recent studies have demonstrated successful production of dulaglutide analogs in apoptosis-resistant CHO cell lines, achieving product titers of 1.05 g/L with ≥95% monomer purity and bioactivity comparable to the reference drug .
