Discovery of a new series of 5-HT1A receptor agonists

Starting from compounds previously identified as alpha(1)-adrenoceptor antagonists that were also found to bind to the 5-HT1A receptor, in an attempt to separate the two activities, a new series of 5-HT1A receptor agonists was identified and shown to have high potency and/or high selectivity. Of these, compound 13, which combines high selectivity (5-HT1A/alpha(1) = 151) and good agonist potency (pD(2) = 7.82; E-max = 76), was found to be the most interesting. (C) 2010 Elsevier Ltd.
