Popis: Seven muscarinic antagonists have been studied by the molecular-mechanics method; minimum-energy conformations were analyzed in a search for geometric descriptors correlating with their activity. Two pharmacophore descriptors were found to discriminate between the low-energy conformations of the most and least potent antagonists: the distances between the basic nonaromatic nitrogen atom and (1) the mean plane of the aromatic moiety (NPl) and (2) the centre of the aromatic ring system (NP). Analysis by Classification And Regression Trees ( cart ) confirmed the validity of these descriptors for activity classification.
