Opiate receptor affinity of peptides related to Leu-enkephalin.

Lars Terenius; A. Wahlström; Gunnar Lindeberg; Sune M. Karlsson; Ulf Ragnarsson

Abstract Several analogs of Leu-enkephalin were synthesized by the standard solid phase procedure in order to investigate structural requirements for binding to opiate receptors. Decisive features for receptor interaction seem to be the presence and location of the aromatic side chains of the tyrosine and phenylalanine residues. The terminal amino and carboxyl groups do not contribute significantly to binding affinity.
