Description
Endomorphin-1 (YPWF-amide) is the most potent and selective endogenous agonist for the mu-opiate receptor so far described (Ki = 360 pM; 4’000- and 15’000-fold preference over the delta and kappa receptors). It may be a natural ligand for this receptor. Endomorphin-1 has been shown to inhibit the aggregation of Aβ in vitro and is effective in vivo.
