ligands led to the synthesis of new 1-adamantoyloaminoalkyl derivatives. The impact of substituent variations in the aromatic part of THIQ moiety on 5-HT(1A) and 5-HT(2A) receptor affinities, as well as in vivo functional properties of the investigated compounds were discussed. It was found that those modifications reduced the binding affinity for 5-HT(1A) receptors (in comparison with unsubstituted
1,2,3,4-四氢异喹啉(THIQ)类的5-HT(1A)配体的进一步结构-活性关系(SAR)研究导致了新的1-金刚烷基氨基烷基衍生物的合成。讨论了取代基变化的THIQ部分的芳香部分对5-HT(1A)和5-HT(2A)受体亲和力,以及所研究化合物的体内功能性质的影响。发现这些修饰降低了对5-HT(1A)受体的结合亲和力(与未取代的THIQ衍生物相比)。但是,大多数新化合物仍保持有效的5-HT(1A)配体(K(i)= 4.9-46 nM),并且大多数显示出突触后5-HT(1A)受体的部分激动剂的特征。同时,它们的5-HT(2A)受体亲和力略有增加(K(i)= 40-1475 nM),导致5-HT(2A)/ 5-HT(1A)选择性损失。5-Br,8-OCH3衍生物-最有效的混合5-HT(1A)/ 5-HT(2A)配体产生的突触前5-HT(1A)受体激活并显示5-HT(2A)的性质)受体拮抗剂。
