R3 vs TZ2

R3 and TZ2 represent successive generations of incretin research compounds, distinguished by how many receptors they engage. This overview describes the mechanistic difference in research framing only.

AttributeR3TZ2
Receptor targetGIP + incretin pathway + glucagon (triple)GIP + incretin pathway (dual)
CAS Number2381089-83-22023788-19-2
Molecular Weight4,731.32 g/mol4,813.45 g/mol
ClassTriple agonistDual agonist
Research focusMulti-incretin + glucagon signalingDual-incretin signaling

The added pathway. R3 adds glucagon-receptor agonism on top of the GIP and incretin pathway activity shared with TZ2. Research models use the pair to study the incremental contribution of glucagon-receptor signaling to metabolic endpoints.

Why they are compared. They share the GIP+incretin pathway base, so the comparison isolates the role of the third (glucagon) receptor in next-generation incretin research.

Frequently asked questions

What is the difference between R3 and TZ2?

R3 is a triple agonist (GIP, incretin pathway, and glucagon receptors); TZ2 is a dual agonist (GIP and incretin pathway). The glucagon-receptor activity is the key distinction. Both are Research Use Only.

Why add glucagon-receptor activity?

In research models the glucagon receptor is studied for its role in energy expenditure and lipid metabolism; R3 lets researchers investigate triple-pathway signaling versus dual.
