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-CH(3) showed the highest affinity (K(i)mu=7.45 nM) equal to that of morphine, partial mu-opioid agonism (E(max)=66.6%) in vitro and a moderate antinociception in mice.
