- Abstract
A series of new arylpiperazide derivatives of serotonin has been prepared and evaluated as 5-HT1D receptor agonists. Binding experiments at cloned human 5-HT1D alpha, 5-HT1D beta, and 5-HT1A receptors show that all the compounds are very potent and selective ligands for 5-HT1D receptor subtypes. Functional activity studies (contraction of the New Zealand white rabbit saphenous vein) demonstrate that most of the derivatives behave as full agonists. Among them, the aryl sulfonamide derivative 5q (pD2 = 8.33 compare to 5.75 for sumatriptan) was also identified as a very potent agonist in inhibiting the forskolin-mediated cyclase coupled to 5-HT1D beta receptors (EC50 = 0.52nM).
