PE 22-28

Description

PE 22-28 is a synthetic peptide derived from neuropeptide Y (NPY), engineered to selectively activate the Y2 receptor subtype. That receptor selectivity is the core research interest: NPY itself binds multiple receptor subtypes with overlapping and sometimes opposing effects on appetite, so PE 22-28 lets researchers isolate Y2-specific signalling from the broader NPY system.

Because Y2 receptor activation is associated with satiety signalling (in contrast to the appetite-stimulating effects of some other NPY receptor subtypes), PE 22-28 is a frequently cited reference compound in comparative appetite-regulation research distinct from the GLP-1/GIP-class compounds elsewhere in this catalogue.
