Abstract :
The 2′,6′-dimethyl-l-tyrosine (Dmt) enhances receptor affinity, functional bioactivity and in vivo analgesia of opioid peptides. To further investigate its direct influence on these opioid parameters, we developed a series of compounds (H–Dmt–NH–X). Among them, H–Dmt–NH–CH3 showed the highest affinity (Kiμ = 7.45 nM) equal to that of morphine, partial μ-opioid agonism (Emax = 66.6%) in vitro and a moderate antinociception in mice.
