Research Abstract

On the basis of our 3D pharmacophore model of kappa agonists, compounds belonging to the binding mode 1, 3, or 4 were synthesized and their binding affinities and agonistic activities for the opioid receptors were evaluated. The test compounds showed selective binding abilities and agonistic activities for the kappa receptor although the strengths of bindings and activities depended on the structures. The binding modes of the compounds were not observed to affect the impedance patterns detected by CellKey SystemTM which was used in the functional assays.
