A range of serotonergic agonists and partial agonists were tested for their capacity to stimulate 5-HT1A receptor mediated GTPg binding in CHO-h5-HT1A membranes. The methoxynaphtylpiperazine ligand, S 14671,was the most potent agonist tested, with virtually full agonist activity, relative to 5-HT Table 1; Fig. 2C consistent with its exceptionally potent and efficacious actions in in vivo functional paradigms. Its analogue, S 14506 was also a highly potent and efficacious ligand (Emax90%) in agreement with previous in vivo studies ( Schreiber et al., 1994 ). (+)UH 301 exhibited partial agonist activity at 5-HT1A receptors |

Together, these data show that (i) [3H]-S 15535 is a highly selective 5-HT1A receptor ligand which labels both G-protein-coupled and uncoupled 5-HT1A receptors, (ii) antagonists, such as WAY 100,635, which yield monophasic isotherms in competition with both [3H]-agonists and [3H]-antagonists, are not sensitive to the G-protein coupling state of the receptor, but (iii) spiperone and methiothepin behaved as inverse agonists, their competition isotherms with [3H]-S 15535 being modulated in an opposite manner to those of agonists. |
