  Unique High-Affinity Synthetic μ-Opioid Receptor Agonists with Central- and Systemic-Mediated Analgesia

  摘要：

  Unique opioid mimetic substances containing identical N-terminal aromatic residues separated by an unbranched alkyl chain containing two to eight methylene groups were developed. Regardless of the length of interposing alkyl chain, the bis-Tyr and bis-Phe compounds were inactive; however, replacement by a single Dint (2',6'-dimethyl-L-tyrosine) residue enhanced activity by orders of magnitude. Moreover, the bis-Dmt compounds were another 10-fold more potent with an optimum intra-aromatic ring distance of about four to six methylene units. 1,4-Bis(Dmt-NH)butane (7) had high mu-opioid receptor affinity (K-i = 0.041 nM) and functional mu-opioid agonist bioactivity (IC50 = 5.3 nM) with in vivo central (intracerebroventricular) and systemic (subcutaneous) analgesia in mice (1.5- to 2.5-fold greater than and 10-12% relative to morphine, respectively); these activities were reversed by naloxone to the same degree. It appears that the bis-Dmt compounds indiscriminately act as both message and address domains.
