GLP-3-R
Tri-receptor incretin research analog
How researchers describe GLP-3-R
Multi-receptor incretin analog reported in published preclinical work to engage GLP-1R, GIP-R, and glucagon receptor pathways in cultured cells and rodent models. Investigators studying this compound focus on cAMP/PKA-mediated signaling cascades downstream of these class-B GPCRs and their effects on insulin and glucose-handling endpoints in vitro.
- GLP-1R / GIP-R / GCGR (class-B GPCRs)
- cAMP → PKA → CREB
- PI3K / Akt insulin sensitivity arm
Lyophilized at −20°C. Reconstituted material is reported in literature to remain stable refrigerated for ~4 weeks under sterile handling.
