A novel series of highly potent human 5-HT1D agonists, dimethyl-2-[6-substituted-indol-1-yl]-ethyl}-amine, was synthesized. Structure-activity relationship (SAR) investigation revealed 4-[1-(2-dimethylamino-ethyl)-1H-indol-6-yl]-tetrahydro-thiopyran-4-ol, 11b (ALX-2732), as a potent (K-i = 2.4 nM) agonist at the human 5-HT1D receptor with good selectivity over the other serotonin receptor subtypes. This compound demonstrated favorable in vitro metabolic stability in human and rat liver microsomes and was found to be orally bioavailable in rats (F-po = 51%) (C) 2003 Elsevier Ltd.
