This paper deals with the application of a Monte-Carlo (MC)-based conformational analysis carried out in water an a set of known beta (3)-adrenergic ligands. On the basis of their conformation at the global minimum, the molecules under study can be grouped into two clusters: the `extended' and the `folded' cluster. Each cluster is identified by well-defined values of torsion angles and distances between the pharmacophoric groups. It is worth noting that a ligand included in the cluster characterized by an extended conformation invariably shows a higher affinity for the human beta (3)-adrenoreceptor with respect to the corresponding rodent receptor.

Abstract
This paper deals with the application of a Monte-Carlo (MC)-based conformational analysis carried out in water an a set of known beta (3)-adrenergic ligands. On the basis of their conformation at the global minimum, the molecules under study can be grouped into two clusters: the `extended' and the `folded' cluster. Each cluster is identified by well-defined values of torsion angles and distances between the pharmacophoric groups. It is worth noting that a ligand included in the cluster characterized by an extended conformation invariably shows a higher affinity for the human beta (3)-adrenoreceptor with respect to the corresponding rodent receptor.
