8-Aminocyclazocine analogues: synthesis and structure–activity relationships
摘要:
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.
