Design, synthesis, and SAR analysis of novel selective σ1 ligands
摘要:
A new series of arylalkyl- and alkenylamines was designed, synthesized, and evaluated for binding to sigma(1) and sigma(2) receptors. Many compounds exhibited nanomolar affinity for sigma(1) subtype receptor with good selectivity over sigma(2). A molecular modeling study was conducted in order to rationalize the experimental data, and the structure-receptor affinities are discussed. (c) 2006 Elsevier Ltd. All rights reserved.
二烷基氨基烷基萘的外消旋混合物和对映异构体在本文中被描述为新型镇痛剂,其功效与吗啡相似或更高。报道了纯对映异构体的合成和分离以及对绝对构型的研究。外消旋体的拆分通过使用Chiralpak AD柱的制备型液相色谱来完成。在对(+)-苄基-(3-羟基-3-萘-2-基-丁基)二甲基溴化铵的X射线晶体学分析以及CD和NOESY 1 H NMR的比较研究的基础上进行了构型分配拆分对映体的光谱。描述了通过热板试验对止痛活性的药理学评价。
In order to investigate the molecular features involved in sigma receptors (sigma-Rs) binding, new compounds based on arylalkylaminoalcoholic, arylalkenyl- and arylalkylaminic scaffolds were synthesized and their affinity towards sigma(1)- and sigma(2)-Rs subtypes was evaluated. The most promising compounds were also screened for their affinity at mu-opioid, delta-opioid and kappa-opioid receptors. Biological results are herein presented and discussed. (C) 2009 Elsevier Ltd.
