  Synthesis of naltrexone-derived .delta.-opioid antagonists. Role of conformation of the .delta. address moiety

  摘要：

  Naltrindole (1) (NTI) is a highly potent and selective delta-opioid receptor antagonist. In an effort to understand the origin of the high potency, affinity, and selectivity of NTI, we have examined the conformational role of its indolic benzene moiety through the synthesis of related naltrexone derivatives 3-8, which contain the benzene moiety in different orientations and at different attachments in the molecule. One of these naltrexone derivatives, 5, whose 7-indanyl benzene moiety is orthogonal to ring C of the morphinan system, is a potent F-opioid receptor antagonist in vitro and in vivo. Computer-assisted molecular overlay studies of the minimized structures (2-8) revealed the importance of the position of the benzene moiety for effective interaction with delta-opioid receptors. In compounds 2, 4, and 5, the aromatic ring falls in the same region of space as that of the indolic benzene moiety of NTI, and all of these ligands possessed significant activity at delta-opioid receptors. Analogues (3 and 6-8) which were shown to have relatively weak delta-opioid receptor antagonist potency have their aromatic groups located in a space that is different from that of the more potent analogues.

  The 7-benzylidenenaltrexone (BNTX) derivatives 2a–v, 3a–c, 13a–c, and 14a were synthesized from naltrexone (1) and evaluated for their antitrichomonal activity. The structure-activity-relationship studies found that 4-iodo-BNTX (2g) showed the highest activity (IC50 = 10.5 µM) and the affinity for the opioid receptor was less important for antitrichomonal activity against Trichomonas vaginalis.

  Derivatives of 7-benzylidenenaltrexone (BNTX), which was recently reported to be an effective chloroquine (CQ)-resistance reverser, were synthesized and evaluated for their CQ-resistance reversing activities. The synthesized derivatives showed CQ-resistance reversing effects. They also reacted with glutathione (GSH) both enzymatically and chemically, and inhibited glutathione reductase activity. 7-Benzyl derivative, which was obtained by reduction of the olefin group in alpha,beta-unsaturated ketone structure of BNTX, also exhibited CQ-resistance reversing effect, but its potency was significantly lower than that of BNTX. These outcomes suggested that the decrease in GSH level could be one of the mechanisms of CQ-resistance reversing effects induced by BNTX derivatives. (c) 2012 Elsevier Ltd. All rights reserved.
