one heteroatom (N, O, or S) on the 5-substituent of the indole. This has led to the hypothesis that a 5-substituent capable of participating in hydrogen bonding is critical for conveying high affinity. This article describes the synthesis and biological evaluation of a new series of 5-alkyltryptamine analogues, which does not have a heteroatom in the 5-substituent group. In contrast to the hypothesis
已经观察到报道的5-HT1D受体激动剂在吲哚的5-取代基上具有至少一个杂原子(N,O或S)。这导致了这样的假设:能够参与氢键的5-取代基对于传达高亲和力至关重要。本文介绍了一系列新的5-烷基色胺类似物的合成和生物学评估,这些类似物在5-取代基中没有杂原子。与该假设相反,5-烷基色胺都对人5-HT1D受体表现出高结合亲和力。在吲哚的5-位的亲脂性烷基的大小对5-HT1D结合亲和力具有显着影响。鉴定了在5-位具有叔丁基的化合物,例如9d,10和11。这些类似物显示出高结合亲和力(Ki <
