It has been observed that reported 5-HT(1D) receptor agonists have at least 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, 5-alkyltryptamines all exhibit high binding affinities for the human 5-HT(1D) receptor. The size of the lipophilic alkyl group at the 5-position of the indole has significant impact on the 5-HT(1D) binding affinity. Compounds with a tert-butyl group at the 5-position such as 9d, 10, and 11 were identified. These analogues display high binding affinity (K(i) 1 nM) and moderate receptor selectivity in comparison with known antimigraine agents such as sumatriptan, naratriptan, rizatriptan, and VML-251.
