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 (NPl) and (2) the centre of the aromatic ring system (NP). Analysis by Classification And Regression Trees ( cart ) confirmed the validity of these descriptors for activity classification. |
