log(IC50). Affinities for the 5-HT1A receptors were in the nanomolar range for the best compounds ((+)-11a,23) with a high selectivity versus other 5-HT (5-HT1B, 5-HT2, 5-HT3) or dopamine (D1, D2) receptor subtypes. As for the 3-amino-3,4-dihydro-2H-1-benzopyran series, the dextrorotatory enantiomer (+)-11a showed better affinity and selectivity for 5-HT1A receptors than its levorotatory analogue (-)-11a
在继续研究对5-HT1A受体具有高亲和力的3-氨基-3,4-二氢-2H-1-苯并吡喃衍生物的过程中,我们制备了由Mellin药效团模型设计并通过定量结构选择的刚性螺并苯并吡喃类似物活动关系法主要基于相似度指标。然后合成了一系列在芳香环以及环外螺环氮原子上具有各种取代基的螺[吡咯烷-和哌啶-2,3'(2'H)-苯并吡喃],并评估了它们的血清素能和多巴胺能活性。观察到预测的和实验的结合值之间具有良好的相关性,log(IC50)的平均差为0.2个单位。最佳化合物((+)-11a,23)与其他5-HT(5-HT1B,5-HT2、5-HT3)或多巴胺(D1,D2)受体亚型相比具有较高的选择性。至于3-氨基-3,4-二氢-2H-1-苯并吡喃系列,右旋对映异构体(+)-11a对5-HT1A受体的亲和力和选择性比其左旋类似物(-)-11a更好。化合物(+)-11a在体外被证明是一种完全的激动剂,并且在体内
