Synthesis and biological evaluation of 14-alkoxymorphinans. 14.1 14-ethoxy-5-methyl substituted indolomorphinans with δ opioid receptor selectivity
摘要:
The 5-methyl and 14-ethoxy substituted analogues (compounds 2-4) of the delta opioid receptor antagonist naltrindole showed similar selectivity when compared with the reference drug. Compound 2 was a delta receptor antagonist in the mouse vas deferens preparation (MVD) exhibiting considerably higher selectivity ratios than naltrindole, while compound 4 was found to be a full and potent delta receptor agonist in the MVD.
