Tirzepatide is a synthetic 39-amino-acid peptide that functions as a dual agonist targeting both the glucose-dependent insulinotropic polypeptide receptor (GIPR) and the glucagon-like peptide-1 receptor (GLP-1R) . Its molecular formula is C225H348N48O68 with a molecular weight of approximately 4813.45 g/mol. When you buy tirzepatide for research, you gain access to a well-characterized tool for advancing studies in metabolism, diabetes, and obesity-related research.

What is Tirzepatide?

Tirzepatide (INN, CAS: 2023788-19-2) is a 39-amino-acid peptide that incorporates several structural features designed to enhance its stability and pharmacokinetic profile. Key features include:

• Aib residues at positions 2 and 13 for improved proteolytic stability 

• A C20 fatty diacid moiety attached to the lysine side chain via a linker, promoting albumin binding and prolonged half-life 

• PEG-like spacer (AEEA) to enhance solubility and stability 

Key identifiers:

• CAS Number: 2023788-19-2

• Molecular Formula: C225H348N48O68

• Molecular Weight: 4813.45 g/mol

• Synonyms: Tirzepatide, 泰瑞帕肽, 替尔泊肽

• Purity: ≥99% verified by HPLC

Mechanism of Action in Research

Tirzepatide exerts its effects through balanced dual receptor engagement:

GIP Receptor Agonism
Tirzepatide is highly selective for the GIP receptor, with similar activity to the native GIP hormone. GIP receptors are widely distributed in pancreatic α and β endocrine cells, adipocytes, heart, vasculature, immune cells, gut, and kidney .

GLP-1 Receptor Agonism
The activity of tirzepatide on the GLP-1 receptor is comparatively lower than native GLP-1 hormone, yet it retains sufficient activity to contribute to its therapeutic effects .

Complementary Signaling Pathways
Research indicates that simultaneous activation of both receptors produces synergistic effects—the GIP component may help reduce nausea while enhancing insulin secretion and improving beta-cell survival .tirzepatide peptide for research

Scientific Research Applications

Metabolic Research

Tirzepatide has demonstrated significant effects in research on obesity and type 2 diabetes. In Phase 2/3 trials, participants achieved substantial weight loss—up to 15-20% at higher doses . This is attributed to complementary effects on appetite suppression (GLP-1R) and metabolic regulation (GIPR).

Neuroprotection and Brain Research

Tirzepatide administration has been shown to attenuate high-fat diet-induced cognitive impairment in murine models. Key mechanisms include suppressing microglia activation, alleviating oxidative stress, and inhibiting NLRP3 expression through SIRT3 upregulation . This suggests potential neuroprotective applications.

Cardiometabolic Research

Tirzepatide has shown improvements in metabolic markers including BMI, waist circumference, HbA1c, lipids, and blood pressure . These effects make it relevant for research into cardiometabolic health and inflammation.

Drug Delivery Research

Tirzepatide has been investigated as a model compound for advanced delivery systems, including milk-derived small extracellular vesicles  and novel fluorescent probes for receptor visualization .

FAQ Section

: What is tirzepatide and how does it work in research?

A: Tirzepatide is a 39-amino-acid peptide that acts as a dual agonist targeting both the GIP and GLP-1 receptors. It is studied for its effects on weight loss, glucose metabolism, and potentially neuroprotection.

: What are the key research applications for tirzepatide?

A: Tirzepatide is used in metabolic research, obesity studies, neuroprotection investigations, cardiometabolic research, and drug delivery studies.

: What is the difference between tirzepatide and semaglutide?

A: Tirzepatide is a dual GIP/GLP-1 receptor agonist, while semaglutide is a selective GLP-1 receptor agonist. This broader receptor activity profile may contribute to tirzepatide’s effects on body weight reduction .

: What purity level can I expect?

A: All batches are tested to ensure ≥99% purity by HPLC analysis. Certificates of Analysis are available upon request.

: Is this product for human use?

A: No. Our tirzepatide is manufactured strictly for research use only (RUO). It is not intended for human consumption or clinical applications.
