Description

Research Snapshot

What it is:
Mazdutide is a peptide-based dual receptor agonist that activates both the GLP-1 receptor (GLP-1R) and glucagon receptor (GCGR). It has been investigated extensively for its effects on metabolic signaling, glucose regulation, energy balance, and body-weight-related physiology.

Researchers study it for:

• GLP-1 and glucagon signaling
• Glucose and metabolic regulation
• Energy expenditure and energy balance
• Lipid metabolism
• Body composition and weight-related physiology
• Cardiometabolic signaling
• Liver and metabolic physiology

Target pathway(s):
GLP-1 Receptor (GLP-1R) • Glucagon Receptor (GCGR) • Glucose & Insulin Signaling • Energy Metabolism

What Is Mazdutide?

Mazdutide, also known as IBI362 or LY3305677, is a dual GLP-1/glucagon receptor agonist originally derived from an oxyntomodulin-based molecular design. Unlike compounds that selectively activate GLP-1 receptors, mazdutide is designed to engage both GLP-1 and glucagon receptor pathways.

GLP-1 signaling is closely involved in glucose-dependent insulin regulation, gastrointestinal physiology and metabolic signaling, while glucagon receptor signaling influences hepatic glucose metabolism and energy regulation.

The combination of these two receptor activities makes mazdutide particularly interesting for investigating how multiple metabolic pathways interact to regulate energy balance, glucose homeostasis and broader cardiometabolic physiology. Clinical research has evaluated outcomes including body weight, glucose regulation, lipid markers and other metabolic parameters.

Why Are Researchers Interested?

Current scientific research investigates Mazdutide in relation to:

• GLP-1 receptor signaling
• Glucagon receptor signaling
• Glucose homeostasis
• Insulin-related metabolic pathways
• Energy expenditure and metabolism
• Lipid metabolism
• Body composition
• Cardiometabolic physiology
• Liver-related metabolic pathways

Because mazdutide activates two metabolically important receptors within a single molecule, it provides researchers with a model for examining how combined GLP-1 and glucagon signaling differs from selective GLP-1 receptor activation.

Ongoing research continues to expand understanding of dual-receptor signaling and its relationship with metabolic regulation and energy homeostasis.
