Abstract (D-Met 2, Pro 5)-enkephalin-N-(β-D-galactopyranosyl) amide, a glycopeptide containing a galactose residue at the C-terminal position of the μ-selective enkaphalin analogue (D-Met 2, Pro 5)-enkaphalinamide, has been synthesized by the liquid phase procedure according to different strategies. Such analogue exhibited a great antinociceptive potency after intracerebroventricular injection in the “in vivo” tail immersion test when ...
