5-HT1B Receptor Antagonist Properties of Novel Arylpiperazide Derivatives of 1-Naphthylpiperazine
Journal of medicinal chemistry, 1997Co-Authors: Catherine Jorand-lebrun, Petrus J. Pauwels, Christiane Palmier, Chantal Moret, Philippe Chopin, Michel Perez, Marc Marien, Serge HalazyAbstract:A new series of arylpiperazide derivatives of 1-naphthylpiperazine of general formula 4 has been prepared and evaluated as 5-HT1B antagonists. Binding experiments at cloned human 5-HT1A, 5-HT1B, and 5-HT1D receptors show that these derivatives are potent and selective ligands for 5-HT1B/1D subtypes with increased binding selectivity versus the 5-HT1A receptor when compared to 1-naphthylpiperazine (1-NP). Studies of inhibition of the forskolin-stimulated cAMP formation mediated by the human 5-HT1B receptor demonstrate that the nature of the arylpiperazide substituent modulates the intrinsic activity of these 1-NP derivatives. Among them, 2-[[8-(4-methylpiperazin-1-yl)naphthalen-2-yl]oxy] -1-(4-o-tolylpiperazin-1-yl)ethanone (4a) was identified as a potent neutral 5-HT1B antagonist able to antagonize the inhibition of 5-HT release induced by 5-CT (5–Carbamoyltryptamine) in guinea pig hypothalamus slices. Moreover, 4a was found to potently antagonize the hypothermia induced by a selective 5-HT1B/1D agonist in vivo in the guinea pig following oral administration (ED50 = 0.13 mg/kg).
