Identity

PE 22-28 is identified in this primary paper as a seven-amino-acid analogue designed from spadin degradation products. The cited paper, rather than a marketplace label, is the basis for this identity description.

Sources: PubMed, National Library of Medicine

Research context

The authors tested channel activity in hTREK-1/HEK cells and examined behavioural, neurogenesis and synaptogenesis measures in mice. These are preclinical experiments.

Sources: PubMed, National Library of Medicine

Evidence boundary

The reported antidepressant-like measures in mice do not demonstrate treatment of depression or any other condition in people. No personal-use, safety or product-quality conclusion follows from this study.

Sources: PubMed, National Library of Medicine

This source-linked record does not establish a diagnosis, treatment effect, product quality, or personal suitability.

Channel and mouse behavioural findings can guide further research, but they do not establish whether the compound reaches the relevant human tissue or has an acceptable risk profile.
