  Endomorphin-2 with a β-Turn Backbone Constraint Retains the Potent μ-Opioid Receptor Agonist Properties

  摘要：

  The constitutional similarity with different secondary structure preference between the Aba-Gly and the spiro-Aba-Gly scaffolds were exploited to design the novel endomorphin-2 analogs Tyr-spiro-(R/S)-Aba-Gly-Phe-NH2 (1 and 2) and Tyr-(R/S)-Aba-Gly-Phe-NH2 (3 and 4). The (R)-spiro analog 1 was found to be a potent and selective mu-opioid agonist/partial agonist (K-i mu = 29.3 nM, IC50 = 50 nM, K-e = 0.57). NMR experiments and molecular modeling indicated that its backbone adopts mainly a U-turn in aqueous solution.
