Mechanism of Action (MOA) Overview
Both GLP-1 and GIP are enteropancreatins secreted by the human gastrointestinal mucosa. While GLP-1 binds to pancreatic islet cells to stimulate insulin secretion, delay gastric emptying, and suppress appetite, the GIP component acts synergistically to inhibit gastric acid/pepsin secretion and further amplify insulin release. This dual-action mechanism significantly outpaces leading single-target GLP-1 drugs (such as Semaglutide) in comprehensive metabolic regulation.
Core R&D and Manufacturing Advantages
1. Dual Target Innovation
As the world's first GIP/GLP-1 receptor dual agonist API, it offers a revolutionary mechanism that produces synergistic hypoglycemic and weight-regulating effects, providing a superior foundation for next-generation drug formulations.
2. High Biological Activity
Demonstrates significant efficacy and high potency in assay testing, driven by our meticulous SPPS synthesis method that preserves the exact 39-amino acid sequence and C20 lipid chain integrity.
3. Long-Term Formulation Potential
Designed for long-term convenience in downstream formulations, supporting the development of stable, once-weekly administration profiles for chronic metabolic management.
Downstream Formulation Targets (Applications)
Our high-purity Tirzepatide API is strictly supplied for formulation R&D, pilot manufacturing, and generic drug development targeting:
Metabolic Therapeutics
Type 2 Diabetes (T2D) formulation development.
Obesity and severe overweight management drug design.
Research targeting the improvement of metabolic indicators (blood lipids, blood pressure, fatty liver).
Cardiovascular & Academic Research
Development of formulations aimed at reducing cardiovascular risk complications.
In-vitro and in-vivo scientific research on enteropancreatin pathways.
Exploration of potential expanded clinical indications (currently under global development).
