Resum

The surface activity and opioid potency of peptide analogues of enkephalins are described. The molecules under study have as a general formula: Tyr-D · Met-Gly-Phe-Pro-NH-(CH₂)_n-CH₃, n being 5, 9 or 13. The interaction of these peptide-alkylamides with PC, PS, PI and GM₁ monolayers and their opioid activity measured by the GPI (guinea pig ileum) test are highly dependent on the hydrophobicity of the molecule. Moreover, the GPI muscle contraction records show a strong hydrophobic interaction between the peptides and the bilayer components, that holds the molecules anchored to the membrane and increases the duration of the effect.
