  Redefining the structure–activity relationships of 2,6-methano-3-benzazocines. Part 2: 8-formamidocyclazocine analogues

  摘要：

  High affinity binding for p and K opioid receptors has been observed in analogues of cyclazocine, ethylketocyclazocine and naltrexone where the prototypic (of opiates) phenolic OH group was replaced with a formamide (-NHCHO) group. For the 8-formamide analogue of cyclazocine, binding is highly enantiospecific (eudismic ratios similar to2000 for mu and kappa) with K-i values less than or equal to 1 nM observed for the (2R,6R, 11R)-isomer, (-)-4. A preliminary SAR revealed that affinity is very sensitive to substitution on the formamide appendage. (C) 2003 Elsevier Science Ltd. All rights reserved.

  Syntheses and Opioid Receptor Binding Affinities of 8-Amino-2,6-methano-3-benzazocines

  摘要：

  8-Amino-2,6-methano-3-benzazocine derivatives have been made using Pd-catalyzed amination procedures, and their affinities for opioid receptors were assessed. The 8-amino group was hypothesized to be a replacement for the prototypic 8-OH substituent for 2,6-methano-3-benzazocines and related opiates. This OH group is generally required for binding yet is implicated in unfavorable pharmacokinetic characteristics such as low oral bioavailability and rapid clearance via O-glucuronidation. The core structures in which the 8-OH group was replaced were cyclazocine and its enantiomers, ethylketocyclazocine and its enantiomers, ketocyclazocine, and Mr2034. Many new analogues had high affinity for opioid receptors with several in the subnanomolar range. Highest affinity was seen in analogues with secondary 8-(hetero)arylamino appendages. Binding to opioid receptors was enantioselective with the (2R,6R,11R)-configuration preferred and high selectivity for mu and kappa over delta opioid receptors was observed within the series. Several derivatives were shown to have intrinsic opioid-receptor-mediated activity in [S-35]GTPgammaS assays.

  Opioid binding affinities were assessed for a series of cyclazocine analogues where the prototypic S-OH substituent of cyclazocine was replaced by amino and substituted-amino groups. For mu and kappa opioid receptors, secondary amine derivatives having the (2R,6R,11R)-configuration had the highest affinity. Most targets were efficiently synthesized from the triflate of cyclazocine or its enantiomers using Pd-catalyzed amination procedures. (C) 2000 Elsevier Science Ltd. All rights reserved.
