Ergoline Derivatives as a Probe for Featuring the 5-HT 1A Receptor Pharmacophore


A 5-HT1A pharmacophore has been obtained employing a set of rigid templates encompassing the 5-HT structure. The use of rigid templates allowed us to overcome the discrepancy found when flexible structures where the energy of the active conformers are sometimes higher than the global minimum energy are used. On the basis of the results herein reported the three-dimensional requirements necessary for the binding interaction have been defined within this set of molecules. In this study forbidden zones of the receptor have been characterised. The pharmacophore model derived places some agonist/antagonist pharmacophore models appeared in the literature in question
