to the kappa opioid receptor (K(i)=21.5 nM). Compound (-)-7b showed good selectivity for the kappa opioid receptor in comparison to the sigma1 and sigma2 sites and to the mu and delta opioid receptors. A correlation of the binding affinities between cis-(-)- and cis-(+)-N-deoxynormetazocine derivatives show that both isomers of the deoxy analogs have similar sigma1 and sigma2 binding profiles as the
描述了顺式(+)-和顺式-(-)-N-亚乙基氨基-N-去甲甲氧嘧啶类似物的合成,并评估了它们与sigma1,sigma2和κ阿片受体的亲和力。顺式(+)-脱氧化合物对sigma1受体的纳摩尔摩尔K(i)值显示出高的sigma / kappa选择性,而在顺式(-)-N-去甲甲唑嗪系列中发现化合物(-)-7b结合对Kappa阿片受体具有纳摩尔亲和力(K(i)= 21.5 nM)。与sigma1和sigma2位点以及mu和delta阿片受体相比,化合物(-)-7b对κ阿片受体表现出良好的选择性。
